New subject: [xwiki-users] Export from 1.7 and import in 1.8

26 Mar 2009

Hi

I think you have to change JAVA_OPTS in the script to start the server.
In my case i replaced "set JAVA_OPTS=-Xmx300m" with "set
JAVA_OPTS=-Xmx512m" to allocate 512M for the java process

You are right

I get this:

Wrapped Exception:

How can I solve it?

  You are right, I cannot open it (using 7zip). But I
rememeber I was able to import earlier backups in other xwiki 1.7. ¿Is there any way to
send all that I have in xwiki1.7 into 1.8? or to see what is corrupting the compressed
file. Or to make a selective export of spaces? 
Looks like the issue is the export from 1.7 which produce corrupted
xar in your case. Do you have any error/warning in the log when you
try to export xar from 1.7 wiki ?

If you want to do selective export you can use
http://code.xwiki.org/xwiki/bin/view/Applications/ImportExportApplication

...

 Thanks,

 Francisco

 Hi,

 Looks like your xar is invalid, are you able to open it (rename it to *.zip) ?
