Plutext

Hi. I'm using Docx4j in a web application deployed on jboss.

Code: Select all

/* tmp is an hibernate object that loads the docx template from a database */
InputStream fileInputStream = new ByteArrayInputStream(tmp.getFile());
LoadFromZipNG load = new LoadFromZipNG();
OpcPackage pkg = load.get(fileInputStream);
ByteArrayOutputStream out = new ByteArrayOutputStream();
SaveToZipFile save = new SaveToZipFile(pkg);
save.save(out);
byte[] bytes = out.toByteArray();
out.close();
return bytes;

But after the execution of this code, the memory consumption of my application raises, and analyzing the memory dumps of the heap memory, i found a lot of doc4x objects no garbage collected.
For example:

Code: Select all

org.docx4j.wml.STBorder (191 objects)
org.docx4j.dml.STShapeType (187 objects)
org.docx4j.dml.STPresetColorVal (140 objects)

Any ideas of what could be the problem?
i think maybe you need more information, please let me know and i will provide it if i can.

thanks,

regards,

Not sure.. does memory use change if you explicitly set pkg=null, save=null, and then GC?

javax.xml.bind.JAXBContext.Context stores the various JAXBContexts statically, but it doesn't look like that accounts for the objects you are seeing.

thank you very much for your response.

Even if i set the variables to null the objects are still on memory.
i have the memory dump but is a 500mb file.
Any tests i could try?

regards,

It seems the unmarshaller may be holding on to objects after it is done. See http://stackoverflow.com/questions/5186 ... marshaller
