We are facing out of memory : Java heap space error while converting docx to html when the document size goes above 300KB and the server hangs. We don't have control on the server parameters.

Code is given below. Would be helpful if there are any solutions.

// Convert .docx file to html file and return .html file as File Object
public File convertDocxToHtml(File inputFile)

Hi,
I'm trying to find a way to allow a person editing a template to define a table stub surrounded by content controls (somehow) which, when processed, will be expanded by both its dimensions.
As OpenDoPE as well as Office 2013 allow definition of repeating content controls for table rows, what this basically comes down to is to somehow managing to coherently define (and later process) repeating content controls on the table columns (OpenDoPE and ...

I'm using docx4j 3.0.0 with Word 2010 and trying to convert a document to pdf using the following sample code, ConvertPDF

public boolean convert(WordprocessingMLPackage wMLP) throws Docx4JException {

// Font regex (optional)
// Set regex if you want to restrict to some defined subset of fonts
// Here we have to do this before calling createContent,
// since that discovers fonts
// String regex = null;
// Windows:
String regex = ".*(calibri|cour|arial|times|comic|georgia|impact|LSANS|pala|tahoma|trebuc|verdana|symbol|webdings|wingding).*";
PhysicalFonts.setRegex(regex);

I'm using latest docx4j-3.0.0 with fop-1.1
I programatically generate a document using docx4j.
I set the following document defaults when generating the document.

Code: Select all

Styles styles = dleReportMLPackage.getMainDocumentPart().getStyleDefinitionsPart().getJaxbElement();   
        DocDefaults docDefaults = styles.getDocDefaults();
        RFonts defaultRPrRFonts = docDefaults.getRPrDefault().getRPr().getRFonts();
        defaultRPrRFonts.setAscii(TIMES_NEW_ROMAN);
        defaultRPrRFonts.setHAnsi(TIMES_NEW_ROMAN);     
        defaultRPrRFonts.setCs(TIMES_NEW_ROMAN);


I then run the sample ConvertToPDF code to convert the document, I get no errors.
public boolean convert(WordprocessingMLPackage wMLP) throws Docx4JException {

// Font regex (optional)
// Set regex if you want to restrict to some ...

I am able to run docx4j within Eclipse. But when I deploy to WebSphere 7+, along with dependent JAR files, I get the following exception. I noticed there was an article for this for Weblogic 12c indicating updating eclipselink.jar. I don't see this under Websphere. I have spent several hours debugging this and am not sure if I am running into conflicts with including JAR files into this app with existing jar files. Any suggestions ...

Hi, There are 15 default core properties in MS word. Is it possible using docx4j to create new core properties or are there other type of properties to make those visible under insert->Quick Parts->Document Property?

There is nice video on youtube how it is done using MS Sharepoint:

Hope this is not something proprietary from Microsoft?

However we have a requirement to Split the table into two separate tables whenever the table goes into a new page and put some text at the top. Something like Table ABC (continued). I can ...
