Hi, I don’t know anything about this code snippet provided by a contributor but I can tell you why the NPE happens.
This code seems to be calling Utils.getContextComponentManager() before calling Utils.setComponentManager(…) to set the component manager to use. note that this code is really not clean/nice and it would benefit if someone would develop a Filter Stream converter extension for jspwiki as it’s been done for confluence, see: * http://extensions.xwiki.org/xwiki/bin/view/Extension/Filter+Application * http://extensions.xwiki.org/xwiki/bin/view/Extension/Filter+Confluence+XML+module Hope it helps, -Vincent On 7 May 2015 at 22:21:26, Khjintcorp (khjintc...@gmail.com) wrote: Sent from my iPhone Hi Vincent I am trying to convert JSPwiki pages to Xwiki pages.For that I used the code which is in the link http://extensions.xwiki.org/xwiki/bin/view/Extension/JSPWiki+To+XWiki+Conversion After I fixed all jar issues in classpath then I ran the program, JspWikiImporter I got the null pointer exception. I saw people posted the same messages in this group. I don’t see the answers for this matter.
