If your objective is to generate PDF documents only (ie you have no need for docx or HTML output), then you might consider an XSL FO templating approach.

That is, you do variable replacement in the XSL FO document.

This could be faster than generating a docx file first each time.

You could use any of the templating libraries for this. Google “java xml templating -sap -hana”

Using a templating library is probably better than working with a lower level Java XML API so you don’t reinvent the wheel.

For example, https://www.thymeleaf.org/ (especially if you are using Spring).

Below is a quick demo of using a template library called pebble to create an invoice:

  <dependency>
    <groupId>io.pebbletemplates</groupId>
    <artifactId>pebble</artifactId>
    <version>3.1.4</version>
</dependency>

This demo shows simple variable replacement, repeating content, and conditional content. Java and XSL FO template attached.

How do you get the XSL FO in the first place? You can create a docx document using Microsoft Word, then convert that to XSL FO using docx4j.

Then you add the templating commands to the XSL FO file using your favourite text editor.

Java code:

import java.io.IOException;
import java.io.StringWriter;
import java.io.Writer;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import com.mitchellbosecke.pebble.PebbleEngine;
import com.mitchellbosecke.pebble.template.PebbleTemplate;

public class PebbleFoTemplating {

public static void main(String[] args) throws IOException {

PebbleEngine engine = new PebbleEngine.Builder().build();
PebbleTemplate compiledTemplate = engine.getTemplate(System.getProperty("user.dir") + "/invoice_fo.xml");

Map<String, Object> context = new HashMap<>();

context.put("name", "Mitchell");

// repeat demo, see https://pebbletemplates.io/wiki/tag/for/
List<Fruit> repeat_fruit = new ArrayList<Fruit>();
repeat_fruit.add(new Fruit("apples", "$20"));
repeat_fruit.add(new Fruit("oranges", "$40"));
context.put("fruitList", repeat_fruit);

// condition, see https://pebbletemplates.io/wiki/tag/if/
context.put("condition1", Boolean.FALSE);


Writer writer = new StringWriter();
compiledTemplate.evaluate(writer, context);

String output = writer.toString();
System.out.println(output);

}

static class Fruit {

Fruit(String name, String price) {
this.name=name;
this.price=price;
}

public String name;
public String price;
}

}

documents4j can also be used to update the TOC page numbers in your docx file.

For this, there are 2 adjustments to our previous post.

The first is that you convert to(target).as(DocumentType.DOCX), not DocumentType.PDF, so you get docx output.

The second is that you need a customised word_convert.vbs containing, for example:

    ' Update TOC
    wordDocument.TablesOfContents(1).UpdatePageNumbers

This code will update the first TablesOfContents.

See further https://github.com/documents4j/documents4j/blob/master/documents4j-transformer-msoffice/documents4j-transformer-msoffice-word/src/main/resources/word_convert.vbs

word_convert.vbs is typically found in your documents4j-transformer-msoffice-word.jar

Generating high fidelity PDF output from Office documents has always been a challenge, given the “long tail” of features which are possible in docx/pptx/xlsx files.

For Word documents, it is easy enough to output paragraphs of text, tables and images. But add in VML, DrawingML, equations, SmartArt, and fidelity becomes a challenge.

If your documents are constrained, you may be able to find a suitable conversion tool. Plutext’s PDF Converter was a good example of this. It worked well on a growing range of documents.

But ultimately, if you want great fidelity on a unconstrained set of files, you need to be using Microsoft’s own Office layout engine.

There are various ways to do that, for example https://developer.microsoft.com/en-us/graph/examples/document-conversion

For Java developers, a good solution is documents4j.

It uses Office and the Microsoft Scripting Host for VBS on the conversion machine, so that machine must Microsoft Windows.

Documents4j can run either a “LocalConverter” or a “RemoteConverter”.

Using a LocalConverter is as simple as:

import java.io.File;
import java.util.concurrent.Future;
import java.util.concurrent.TimeUnit;

import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;

public class ToPDF {

	public static void main(String[] args) {

		File wordFile = new File( System.getProperty("user.dir")+"/input.docx" ); 
		File target = new File( System.getProperty("user.dir")+"/output.pdf" );
		
		IConverter converter = LocalConverter.builder()
                .baseFolder(new File("C:\\temp"))
                .workerPool(20, 25, 2, TimeUnit.SECONDS)
                .processTimeout(30, TimeUnit.SECONDS)
                .build();		
                
       Future<Boolean> conversion = converter
                                .convert(wordFile).as(DocumentType.MS_WORD)
                                .to(target).as(DocumentType.PDF)
                                .prioritizeWith(1000) // optional
                                .schedule();
               
	}

}

From Maven, you just need these dependencies:

		<dependency>
			<groupId>com.documents4j</groupId>
			<artifactId>documents4j-local</artifactId>
			<version>1.1.1</version>
		</dependency>

		<dependency>
			<groupId>com.documents4j</groupId>
			<artifactId>documents4j-transformer-msoffice-word</artifactId>
			<version>1.1.1</version>
		</dependency>

		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-simple</artifactId>
		</dependency>

For a successful conversion, your logs will contain:

[main] INFO com.documents4j.conversion.msoffice.MicrosoftWordBridge - From-Microsoft-Word-Converter was started successfully
[main] INFO com.documents4j.job.LocalConverter - The documents4j local converter has started successfully
[pool-1-thread-1] INFO com.documents4j.conversion.msoffice.MicrosoftWordBridge - Requested conversion from input.docx (application/vnd.com.documents4j.any-msword) to output.pdf (application/pdf)

I was looking for a way to convert swagger2markup markdown output to docx using Java (as opposed to Pandoc).

I found flexmark-java which describes itself as:

Java Markdown parser with source level AST. CommonMark 0.28, emulation of: pegdown, kramdown, markdown.pl, MultiMarkdown. With HTML to MD, MD to PDF, MD to DOCX conversion modules.

Its MD to DOCX is in flexmark-docx-converter module, which happily, uses docx4j under the covers.

I tried it, and found it works nicely, the exception being table rendering if you open the resulting docx in LibreOffice (Word automatically sets the column widths, but in LibreOffice 5.3 Writer, the column widths are bad and painful to fix).   The underlying issue is that markdown doesn’t specify column widths, and in docx4j, we don’t provide an algorithm to help the user set sensible values.

Development of flexmark-docx-converter was  sponsored by Johner Institut GmbH (medical device documentation)

The documentation for flexmark-docx-converter is at https://github.com/vsch/flexmark-java/wiki/Docx-Renderer-Extension

That page says:

Word does not handle inserted HTML very well.

It would be quite straightforward to use docx4j-ImportHTML to work around that

TLDR

Current 3.3.x Docx4j works with WebSphere versions 8.5.5.9 and 9.0.0.5 in WebSphere’s default configuration (tested with IBM Java 8, which is not the default in WebSphere 8.5.5.9).

docx4j 3.3.7 contains an important fix for errorsCount where XLXP2 is in use with fallback JAXBContext of Sun/Oracle or reference implementation (see below for context).

Scope/Assumptions

Our testing was based around the following assumptions:

• IBM JDK (not Sun/Oracle)
• IBM JAXB (see below)
• Xalan is available for use via System.setProperty(“javax.xml.transform.TransformerFactory”, org.apache.xalan.transformer.TransformerImpl)

Out of Scope of testing: OSGi. Others have done some work on OSGi in the past though; see https://github.com/uncleit/docx4j-osgi/blob/master/pom.xml or https://github.com/kimios

JAXB Background

IBM has their own proprietary JAXB implementation. By default, WebSphere uses com.ibm.xml.xlxp2.jaxb, which has the concept of fallback/ MarshallerProxy. The actual implementation it uses is in com.ibm.jaxb.tools.jar.

It is possible to configure WebSphere to instead use the JAXB implementation in the Sun/Oracle JRE, but usually you would not do this if you are using the IBM JDK.  Alternatively, your application could use MOXy JAXB (by including the relevant jars).

Here we tested with WebSphere’s default, namely:

Primary JAXBContext:
bundleresource://138.fwk797973828/com/ibm/xml/xlxp2/jaxb/JAXBContextImpl.class,
Version: 1.6.2-jaxb,
Fallback JAXBContext:
bundleresource://11.fwk797973828/com/ibm/jtc/jax/xml/bind/v2/runtime/JAXBContextImpl.class Build-Id: null

For more information, see https://stackoverflow.com/questions/48700004/does-webspheres-jaxb-marshallerproxy-use-the-reference-implementation

WebSphere has property: com.ibm.xml.xlxp.jaxb.opti.level (see https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.0.0/com.ibm.websphere.nd.doc/info/ae/ae/xrun_jvm.html#com.ibm.xml.xlxp.jaxb.opti.level ):

• At level=0, optimization methods are not enabled;
• At level=3 (default), both unmarshalling and marshalling optimization methods are enabled.

In our testing, we used values 0 and 3 (or not set).

WebSphere has several other JAXB related properties which we left at their default settings.

ErrorsCount

Docx4j contains a class JaxbValidationEventHandler, which is responsible for handling unexpected content (both mc:AlternateContent which is common, and certain other errors in an incoming docx).

In the JAXB reference implementation, there is a method shouldErrorBeReported(); see https://github.com/javaee/jaxb-v2/blob/master/jaxb-ri/runtime/impl/src/main/java/com/sun/xml/bind/v2/runtime/unmarshaller/UnmarshallingContext.java#L1350

Previously errors (ie unexpected content) were not ignored if UnmarshallingContext.getInstance().parent.hasEventHandler()

Some time around 2015, JAXB was changed so that after unexpected content has been encountered 10 times (ie in 10 docx parts), the error won’t be reported (ie docx4j’s JaxbValidationEventHandler won’t be invoked, so docx4j doesn’t have the opportunity to deal with the content error, with the result that content is silently dropped).

Recent versions of docx4j work around this, by resetting the error counter, and docx4j 3.3.7 builds on this with an important fix for errorsCount where XLXP2 is in use with fallback JAXBContext of Sun/Oracle or reference implementation

Test Results

With environment WebSphere 9.0.0.4, current docx4j/Plutext releases work well.

With environment: WebSphere 8.5.5.13 (WebSphere 8.5.5.9 upgraded in order to run IBM Java 8),  current docx4j/Plutext releases work well.

(Older Java should also be ok, but was outside the scope of testing)

Methodology Notes

In testing, there are several things to be aware of:

1. WebSphere might re-use a jar in multiple webapps. In case of unexpected results, ensure you don’t have different versions of the same jar in other webapps, stop the server, clearClassCache, and restart.
2. If you are looking for JaxbValidationEventHandler log entries but cannot see them, double check that your jar files do not contain another log4j.xml.

Java 2 Security

If you have Java 2 Security enabled in WebSphere, you will need certain permissions enabled in policy settings.

With FarGate, you have to specify a task size:

Load testing with JMeter, I have found that 2 vCPU works well for the Task CPU setting.  The minimum Task Memory you can set for 2 vCPU’s is 4GB.  (The PDF Converter doesn’t use that much RAM, so it would be good to be able to specify just 1GB, particularly since FarGate pricing includes a cost per GB)

For my load testing (32 parallel conversions), served by 2 tasks:

So, an average of 9.8 sec per conversion (based on a range of documents, some short/quick, others long/slow).

With FarGate, you can set a service to auto-scale, under CPU load or based on incoming requests.

So let’s improve on those response times, by auto-scaling the number of tasks available for processing the incoming PDFs.

How to do this? FarGate tells me my CPU utilization was:

So let’s “update” the service to set auto-scaling to happen at 40%:

Re-running the load test, here are the results:

You can see the response time better than halved, and throughput doubled.

At the end of the test, I can see that it auto-scaled to 10 tasks:

Looking at the load balancer target group, you can see it went from 2 tasks to 5 tasks to 10:

(the test sarted at 23:13 and finished at 11:28; scaling in occurred some time after the test concluded).

You can see from the graph below that the average response times drop as these extra tasks become available.

Running the load test one last time, with 8 tasks in place from the start:

we have an average response time of 2.2 seconds, and we’re converting 12.48 documents per second.

In summary, configuring the cluster so that each task has 2 vCPUs, and auto-scaling when CPU utilization hits 40%, looks like a good place to start tweaking your own instance.

This is the second post in a series on scaling the PDF Converter using Amazon’s FarGate service.

In the first post, we got the PDF Converter running across 2 instances behind a load balancer, in under 20 minutes.

Now, we want to use HTTPS.  The Amazon documentation is at https://docs.aws.amazon.com/elasticloadbalancing/latest/application/create-https-listener.html

First, go to the AWS Certificate Manager (ACM): https://console.aws.amazon.com/acm/home?region=us-east-1#/firstrun/ to request a certificate (for your domain).

Now go to your load balancer, and choose “create listener“. Choose HTTPS.  You should see something like:

(here I’ve used plutext.com, but obviously you’ll have substituted your own domain).

If/when you click “create”, you’ll probably get a warning saying your security group doesn’t allow HTTPS, so click on the security group to allow traffic on port 443.

We’re not quite there yet.  If you try converting using your load balancer endpoint (something like https://EC2Co-EcsEl-1GY7BNHSDU1HTH-1150934046.us-east-1.elb.amazonaws.com:443), you’ll get an error saying the certificate subject name does not match target host name.

To overcome this, you need to update your DNS records so you have a host with the right name resolving to the load balancer.

The recommended way to do this is to use Amazon’s Route53 DNS.

But just to prove what we’ve done so far works, its enough to put an entry in your /etc/hosts file mapping a host covered by your certificate, to the load balancer’s IP address.  Then:

$ curl -v -X POST --data-binary @HelloWorld.docx -o out.pdf https://fargate.plutext.com:443/v1/00
000000-0000-0000-0000-000000000000/convert
Note: Unnecessary use of -X or --request, POST is already inferred.

Now we know it works, you can add a CNAME record at your DNS provider, mapping your chosen host name to the load balancer’s host name.

Remove the entry we added to /etc/hosts, give your CNAME entry time to propogate, then verify the curl command works.

Here’s what it looks like:

Its new features:

• code generation from your selection (no need to use the webapp interface)
• generate PDF output using Plutext’s commercial PDF Converter (either a locally installed instance, or http://converter-eval.plutext.com)
• document sanitisation/anonymisation so you can safely publish it for support purposes
• easy docDefaults manipulation

I’ll run through these one by one.

code generation from your selection

With the old version, you launched a local version of the docx4j webapp to generate code.

You can still do that (click the Load Helper button, then Parts List); its a useful way to see all the parts in your docx.

With this version, if you click the “Inspect selection” button, you’ll see the corresponding XML:

What’s new is the “Java” button.  If you click that, it’ll generate corresponding code, and display that in your web browser:

:

generate PDF output

The “PDF” button generates a PDF.  Either of your whole document, or your selection.

It uses our commercial PDF Converter so its probably most useful:

1. if you want to evaluate that, or
2. have found something which doesn’t convert correctly, and want technical support

It can use either a locally installed instance, or http://converter-eval.plutext.com

You configure that with the “Config” button.

The generated PDF will open in whatever Windows opens PDFs with for you.

document sanitisation/anonymisation

The idea of the “anonymise” button is to make it easy for you to email/publish a docx (or PDF) for support purposes, without giving away sensitive info.

Again, if nothing is selected, it’ll do your whole docx.  Otherwise, just your selection.

The results will be saved to a temporary local docx (so your source docx is unaffected), then opened.

If there is anything potentially sensitive the code can’t remove, it’ll let you know.

The code which does this is at https://github.com/plutext/docx4j/tree/master/src/main/java/org/docx4j/anon

easy docDefaults manipulation

Its sometimes useful to see/edit your doc defaults.

Your changes will open in a new temp docx.

For example, try changing font size (w:sz) from 22 to 42.

You can also make changes in Word’s Paragraph and Font dialogs by pressing the “Set as Default” button, then look here to see how that translates into XML.  Without this, its hard to be sure whether you’ve changed your default styles, or docDefaults!
