When running docx4j 3.0.0 on GAE I get this error:

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)
{
//String str=inputFile.getName().replace(".", " ");
String inputfilepath = inputFile.getAbsolutePath();
int ...

I'm using the following codes to convert a docx file to hmtl:

public class DocxToHTML {

// Config for non-command line version
static {
//inputfilepath = System.getProperty("user.dir") + "/sample-docs/word/sample-docxv2.docx;
inputfilepath = "test3.docx";
save = true;
}

static String inputfilepath;
static boolean save;

public static void main(String[] args) throws Exception {
convert(args);
}

public static void convert(String[] args)
throws Exception {

// Document loading (required)
WordprocessingMLPackage wordMLPackage;
wordMLPackage = Docx4J.load(new java.io.File(inputfilepath));

// HTML exporter setup (required) ...

I am trying to convert a docx file to xhtml, but am getting this exception. Any idea how to resolve this?

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:
http://www.youtube.com/watch?v=VJ-h_qPW7YQ

Hope this is not something proprietary from Microsoft?
