Hi, As an adept of freemind I was very happy to see that a freemind macro exist for xwiki. Unfotunately I have a ClassNotFoundException when tha applet is invoked by the macro, it seems that the FreeMind java library can not be found by the downloaded applet. Here is the Stack Trace of the exception : /Java Plug-in 1.6.0_15 Utilisation de la version JRE 1.6.0_15-b03 Java HotSpot(TM) Client VM charger : classe freemind.main.FreeMindApplet.class introuvable. java.lang.ClassNotFoundException: freemind.main.FreeMindApplet.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.IOException: open HTTP connection failed:http://code.xwiki.org/xwiki/bin/view/Macros/freemind/main/FreeMindAp… at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception : java.lang.ClassNotFoundException: freemind.main.FreeMindApplet.class/ The exception occurs on my instance of xwiki and on the xwiki web site at this example address : http://code.xwiki.org/xwiki/bin/view/Macros/MindMapMacro My instance of xwiki is XWiki Enterprise 1.9.3.22597 on Windows XP SP3 and as you see in the stack trace I have the last 1.6.0_15 java plugin. Can you give me an advice to resolve this problem. Thanks in advance, Julien

My guess is that the freemind jar was removed at some point from xwiki's core. Someone should add some instructions and we should probably make this macro optional and not part of the core platform.

I have already tried to put the freemind.jar in WEB-INF/lib but I have exactly the same problem.

I've just checked and it seems that there isn't mind map xwiki plugin, it's only available under a macro. Julien

New subject: [xwiki-users] MindMap Macro : ClassNotFoundException freemind.main.FreeMindApplet.class

Hello, I had the very same problem today. The MindMap xar was installed and a MindMap space appeared, but visualization failed with CNFE until I put the jar in WEB-INF/lib. Then... xWiki refused to start anymore. I had to remove the jar in order to fix the tomcat launch. Precisely, what I did was dowloading freemind-browser-0.9.0.zip, unzipping it in a new webapps/freemind directory, then creating a *symbolic link* as webapps/xwiki/WEB-INF/lib/freemind.jar targeting webapps/freemind/freemindbrowser.jar ; then NPE occured related to log4j (log4j-1.2.16.jar is present in xwiki libs, but it might not be sufficient ?) Thanks in advance for any help. -- View this message in context: http://xwiki.475771.n2.nabble.com/MindMap-Macro-ClassNotFoundException-free… Sent from the XWiki- Users mailing list archive at Nabble.com.

Hi, I've just tested the macro in my wiki (latest version 3.2-SNAPSHOT) and it works very well without a glitch. It doesn't require any jar file since it uses flash which is embedded in the FreemindMacro page. It's really nice :) BTW there's no mindmap space since the macro creates a page in the XWiki space. The download to use is http://extensions.xwiki.org/xwiki/bin/view/Extension/Freemind+Macro Thanks -Vincent On Jul 13, 2011, at 12:36 PM, tooms4444 wrote:

The http://extensions.xwiki.org/xwiki/bin/view/Extension/Freemind+Macro FreemindMacro works for me under XWiki Enterprise 3.2-milestone-2. Thank you Fabio! The http://extensions.xwiki.org/xwiki/bin/view/Extension/MindMap+Application MindMap Application and the http://extensions.xwiki.org/xwiki/bin/view/Extension/Mindmap+Sitemap Mindmap Sitemap are not working on XWiki Enterprise 3.2-milestone-2. I like the sitemap feature very much! It seems to me that the http://extensions.xwiki.org/xwiki/bin/view/Extension/Mindmap+Sitemap Mindmap Sitemap is generating wrong code. Is there a working version out there? -- View this message in context: http://xwiki.475771.n2.nabble.com/MindMap-Macro-ClassNotFoundException-free… Sent from the XWiki- Users mailing list archive at Nabble.com.
