Sometimes after installation new plugins to Netbeans, if plugins are not compatible, Netbeans can’t run.  Unfortunatelly, deleting these new files from Netbeans directory didn’t helps. So what can we do?

One thing is to open configuration file and disable new plugin.

In Windows7, go to location:

{drive}:\Users\{yourUserName}\AppData\Roaming\NetBeans\{versionNumber}\config\Modules

and find this file, for example:

org-netbeans-modules-websvc-axis2.xml

Try to disable this plugin by putting „false” in tags:

<param name="autoload">false</param>
<param name="eager">false</param>
<param name="enabled">false</param>

If disabling plugins didn’t helps, try to delete all Netbeans configuration by deleting directories (before deleting, you can make a copy of these files):

{drive}:\Users\{yourUserName}\AppData\Roaming\NetBeans\{versionNumber}\
{drive}:\Users\{yourUserName}\AppData\Local\NetBeans\Cache\{versionNumber}\

Unfortunatelly, this operation removes all configurations (servers, loaded projects and other).
