XWiki Servlet Exception

Question

I want to use XWiki for documenting some process, so I downloaded xwiki-enterprise-installer-generic-5.0.1-standard.jar and installed it successfully. When i run the ./start_xwiki.sh file i am able to open xwiki in browser.

The problem what I am facing is when I try to upload any image in the edit page I get this message "There was an error loading the data", when i check logs it says javax.servlet.ServletException: Failed to initialize the XWiki context.

can anyone help me in resolving this exception. Thanks in advance

Here is the stack trace

javax.servlet.ServletException: Failed to initialize the XWiki context.

Answer 1

If the URL that you're using to access the wiki starts with leo, you might be affected by this issue, which will be fixed in the upcoming 5.0.2 release.

Meanwhile, you can work around this by defining the URL for the wiki:

• open /xwiki/bin/edit/XWiki/XWikiServerXwiki?editor=object
• add an object of type XWiki.XWikiServerClass
• put the hostname (leo) in the server field
• save

It should work after that.
