[xwiki-users] doctree plugin

hello people i am trying to modify the doctree 1.5 plugin jar to meet my needs. i have imported the files into my new java project (that were consistent into the jar) and added a new library: commons-collections-3.1 the jar contents:  DocumentTree.java  DocumentTreePlugin.java  DocumentTreePluginApi.java the first one was ok, but the 2 and 3rd have loads of errors. it cannot find my imports: import com.xpn.xwiki.XWikiContext; import com.xpn.xwiki.XWikiException; import com.xpn.xwiki.api.Api; import com.xpn.xwiki.doc.XWikiDocument; import com.xpn.xwiki.plugin.XWikiDefaultPlugin; import com.xpn.xwiki.plugin.XWikiPluginInterface; i don't understand how it is ok in the plugin , but still i am asked to create new interfaces or classes. Take care ,     Gabriela Radu :) www.gabrielaradu.com
