Plutext

I tried to generate a docx document by using an xml string and unmarshalling it. I referred to a document.xml to generate this. The document.xml was :

Code: Select all

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<w:document xmlns:ve="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing" xmlns:w10="urn:schemas-microsoft-com:office:word" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" xmlns:wne="http://schemas.microsoft.com/office/word/2006/wordml"><w:body><w:p w:rsidR="005517ED" w:rsidRDefault="00B076EB"><w:r><w:t xml:space="preserve">Testing </w:t></w:r><w:r w:rsidR="00214F89"><w:rPr><w:noProof/></w:rPr><w:drawing><wp:inline distT="0" distB="0" distL="0" distR="0"><wp:extent cx="5486400" cy="3200400"/><wp:effectExtent l="19050" t="0" r="19050" b="0"/><wp:docPr id="1" name="Chart 1"/><wp:cNvGraphicFramePr/><a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main"><a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/chart"><c:chart xmlns:c="http://schemas.openxmlformats.org/drawingml/2006/chart" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" r:id="rId4"/></a:graphicData></a:graphic></wp:inline></w:drawing></w:r></w:p><w:sectPr w:rsidR="005517ED" w:rsidSect="00B66653"><w:pgSz w:w="12240" w:h="15840"/><w:pgMar w:top="1440" w:right="1440" w:bottom="1440" w:left="1440" w:header="720" w:footer="720" w:gutter="0"/><w:cols w:space="720"/><w:docGrid w:linePitch="360"/></w:sectPr></w:body></w:document>

I used this code - i wanted to generate a document similar to the above document.

Code: Select all

String stringForChart = "<w:p  xmlns:w=\"http://schemas.openxmlformats.org/wordprocessingml/2006/main\" w:rsidR=\"005517ED\" w:rsidRDefault=\"00B076EB\">";
      stringForChart = stringForChart + "<w:r>";
         stringForChart = stringForChart + "<w:t xml:space=\"preserve\">Testing </w:t>";
      stringForChart = stringForChart + "</w:r>";
      stringForChart = stringForChart + "<w:r xmlns:wp=\"http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing\"  w:rsidR=\"00214F89\">";
      stringForChart = stringForChart + "<w:rPr>";
         stringForChart = stringForChart + "<w:noProof/>";
      stringForChart = stringForChart + "</w:rPr>";
      stringForChart = stringForChart + "<w:drawing>";
      stringForChart = stringForChart + "<wp:inline distT=\"0\" distB=\"0\" distL=\"0\" distR=\"0\">";
      stringForChart = stringForChart + "<wp:extent cx=\"5486400\" cy=\"3200400\"/><wp:effectExtent l=\"19050\" t=\"0\" r=\"19050\" b=\"0\"/>";
      stringForChart = stringForChart + "<wp:docPr id=\"1\" name=\"Chart 1\"/>";
      stringForChart = stringForChart + "<wp:cNvGraphicFramePr/>";
      stringForChart = stringForChart + "<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">";
      stringForChart = stringForChart + "<a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/chart\">";
      stringForChart = stringForChart + "<c:chart xmlns:c=\"http://schemas.openxmlformats.org/drawingml/2006/chart\" ";
      stringForChart = stringForChart + "xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\" ";
      stringForChart = stringForChart + "r:id=\"rId4\"/>";
      stringForChart = stringForChart + "</a:graphicData>";
      stringForChart = stringForChart + "</a:graphic>";
      stringForChart = stringForChart + "</wp:inline>";
      stringForChart = stringForChart + "</w:drawing>";
      stringForChart = stringForChart + "</w:r>";
       stringForChart = stringForChart + "</w:p>";
      
       wordMLPackage.getMainDocumentPart().addObject(
             org.docx4j.XmlUtils.unmarshalString(stringForChart) );

My issue is that the code works fine and generates a docx file. When I open the file using Microsoft word it says that its corrupted , in open office I cannot see the chart which I was intending to create. If I add other objects like paragraphs and tables I am able to see them but not this chart. Can you help me with it?

I checked my generated file (after unzipping ) with the docx I created manually.

I noticed that in the _rels package in the orginal (manul) file there is a xml - document.xml.rels
This xml contains references to the relationships :ex:

<Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/chart" Target="charts/chart1.xml" />


My generated folder does not contain this file. Instead the _rels folder only cntains a .rels the contents of which has :


<Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/theme" Target="word/theme/theme1.xml" />

In my code I have references to both themes and charts in the following way :


in = new FileInputStream(System.getProperty("user.dir") + "/Files/theme/theme1.xml");
attachForeignPart(wordMLPackage, wordMLPackage,
externalCtm, "word/theme/theme1.xml", in);


in = new FileInputStream(System.getProperty("user.dir") + "/Files/charts/chart1.xml");
attachForeignPart(wordMLPackage, wordMLPackage.getMainDocumentPart(),
externalCtm, "word/charts/chart1.xml", in);

If I remove the theme relaetd lines from the code - then the Relationship Id="rId4" lines are not present in the .rels file then.

If your attachForeignPart method (based on the ImportForeignPart sample) is doing what you intend, then it should be adding the chart part as a rel of the main document part. Please have a look again in the unzipped file - it ought to be there.

You'll need to alter your attachForeignPart method to return the relId the part is allocated. You need to include this relId in your stringForChart variable where it currently says rId4.

Thank You. I was using the IMportForeignPart method as u mentioned.

I have changed it as suck :

Code: Select all

public static String attachForeignPart( WordprocessingMLPackage wordMLPackage,
         Base attachmentPoint,
         ContentTypeManager foreignCtm,
         String resolvedPartUri, InputStream is) throws Exception{
      
      
      Part foreignPart = Load.getRawPart(is, foreignCtm,  resolvedPartUri, null);
         // the null means this won't work for an AlternativeFormatInputPart
      Relationship r = attachmentPoint.addTargetPart(foreignPart);
      // Add content type
      ContentTypeManager packageCtm = wordMLPackage.getContentTypeManager();
      packageCtm.addOverrideContentType(foreignPart.getPartName().getURI(), foreignPart.getContentType());
      
      System.out.println("Attached foreign part: " + resolvedPartUri);
      return r.getId();
   }

And I am using it as :

Code: Select all

in = new FileInputStream(System.getProperty("user.dir") + "/Files/charts/chart1.xml");
      String rid = attachForeignPart(wordMLPackage, wordMLPackage.getMainDocumentPart(),
            externalCtm, "word/charts/chart1.xml", in);
               stringForChart = stringForChart + "r:id='"+rid+ "' />";

It still gives me the same issue with rels :


<Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/theme" Target="word/theme/theme1.xml" />

And the file is still corrupt.

I put a few log statements and found that after invoking Load.getRawPart for the chart , it returned rId3 . I was expecting rId4.

The part was recognized as a JaxbXmlPart

In the rels document the mapping was :


<Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml" />
<Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/theme" Target="word/theme/theme1.xml" />

In the original document there is a reference to the charts in the document.xml.rels file :

Code: Select all

  <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/chart" Target="charts/chart1.xml" />

Again as my mentioned before : the _rels folder contains the document.xml.rels in the original docx. But mine has rels file.

This is my whole code. I am not adding relationships explicity , do I need to add the document.xml.rels also

Hi,

Please use this code

P objP = (P) XmlUtils.unmarshalString(stringForChart , Context.jc,P.class);

bean.getDoc().getMainDocumentPart().addObject(objP);

Thanks & Regards,
B.V.Suresh Babu.

I did not get the meaning of the code snippet that you posted. What does P refer to here? and the bean?

I can now get the files and folders including document.xml.rels in the correct folders. The document.xml also looks good and almost similar to the manually created file. But I still cannot render the chart. On opening the created file I get the error stating "Error Reading the File"

The difference I noted in the document.xml between the two files was:
In the original file there was :
xmlns:ve="http://schemas.openxmlformats.org/markup-compatibility/2006"
In the docx4j created file there was
xmlns:ns25="http://schemas.openxmlformats.org/drawingml/2006/compatibility"

Again , in my manual file there was a embedded folder with an xlsx containing chart info. In my file that was created via docx4j this folder was not there but the entire contents were there in the chart1.xml .

I want to know how I can debug the error that is causing the error reading file.
