Re: [xwiki-users] Error uploading default pages xar in XWiki 2.7. (solved)

19 Jan 2011

Thanks for your assistance.   My JVM memory was fine (-Xms100m -Xmx1024m
-XX:MaxPermSize=512m), however when I attempted to upload the document onto other pages to
see if it worked elsewhere, I got a totally different stack trace which this time
mentioned the infamous MySql "Packet for query is too large" error.

So I upped the max_allowed_packet in my.cnf (again) this time to 64M (was 32M) and the
problem went away, and I can also upload the default pages xar now without the other error
occurring anymore!

Cheers!

What is your java parameters set to for your Xwiki process.

The parse error makes me thin that the server is starving of memory.

What else is running, try running top while you load and see how low the free memory
goes.

Make sure that you have the free memory as real memory to handle the Xmx  value you have
set.

Cheers

  Hi,

 I have a fresh installation of the XWiki Enterprise 2.7 war file, and I can't upload
the "default XWiki Enterprise wiki" pages.

 Each time I try it always fails, and the logfiles contain a stacktrace which appears to
indicate a NPE at "UploadAction.java:96", however I don't know if this is
the real cause or not.  I couldn't find anything in Jira or the mailing list archives
that matched what I'm seeing.

perform all other functions.  I have installed xWiki into the ROOT context on tomcat.

 Do you get the same exception if you attach the XAR to a different page,
 a new page for instance? Are you able to attach other files, try with
 small ones (a few KB).

 Marius

 Please let me know if anyone can suggest a solution for this, or an alternative method
for installing the default wiki pages.  Full details of the error are below.

 Thanks,
