Import problems

Hi all, I hope I can get some help on this as I really don't know what to do... I'm making the last preparations to move my experimental xwiki to another machine for actual use but my Imports don't work. I can make a backup.xar file using the Export tool but as I try to import it again I get a huge error message. I tried attaching it and sending it with this mail but I got it back because it was too large... The first part of it goes like this: Error number 3232 in 3: Exception while saving attachment Backup.xar of document XWiki.Import Wrapped Exception: Error number 3231 in 3: Exception while loading attachment Backup.xar of document XWiki.Import Wrapped Exception: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=3Dfalse for more info) setter of com.xpn.xwiki.doc.XWikiAttachmentArchive.setArchive com.xpn.xwiki.XWikiException: Error number 3232 in 3: Exception while saving attachment Backup.xar of document XWiki.Import Wrapped Exception: Error number 3231 in 3: Exception while loading attachment Backup.xar of document XWiki.Import Wrapped Exception: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=3Dfalse for more info) setter of com.xpn.xwiki.doc.XWikiAttachmentArchive.setArchive After searching the mailinglist archives I've tried the following: - set the -Xms512m to -Xmx521m in catalina.sh - remove documents with Swedish carachters in their names - made a much smaller .xar file by changing the package.xml file and only including what I left in there. - imported old backups that I know worked back then, but it gives me the same error as all the others. I'm using MySQL, Tomcat, XWiki 1.0 and it has all worked before... Please help! Thanks, //Karin
