     AlternativeFormatInputPart afiPart1 =new AlternativeFormatInputPart(new PartName("/hw.html"));

     afiPart1.setBinaryData(content2.getBytes());

     afiPart1.setContentType(new ContentType("text/html"));

     Relationship altChunkRel1 = wordMLPackage1.getMainDocumentPart().addTargetPart(afiPart1);

     CTAltChunk ac1 =Context.getWmlObjectFactory().createCTAltChunk();

     ac1.setId(altChunkRel1.getId());

     wordMLPackage1.getMainDocumentPart().addObject(ac1);

     wordMLPackage1.getContentTypeManager().addDefaultContentType("html", "text/html");

     wordMLPackage1.save(new java.io.File(new StringResourceModel("upload.path", new Model<String>()).getString()+"/ComparedDFA"+"/updatedContent.docx"));Parsed in 0.017 seconds,  using GeSHi 1.0.8.4

The next version of docx4j will include XHTML importing, including from an altChunk. You can expect a nightly with this in early January.

(At present trunk tip includes XHTML importing, but tables are not yet supported, and you'd need to write a bit of glue to parse the altChunk. I guess there'll be a callback to tidy HTML to XHTML)

Once that is implemented, this problem should go away.

Dear jason thankx for updating me about this, i will wait for january,
meanwhile, can you guide me, where to find some expmple to play with altChunk (glue code example) so that i can export the PDF. I gone through some example that has been
posted on plutext but got confused to call and process.
