About problem of FCKeditor in java error

You must change the servlet url in web.xml

SimpleUploader , Connector

They must be from FCKditor Root!

For exmaple:

I put FCKditor in tomcat_home/FCKditor

The servlet should be:

<servlet-mapping>
<servlet-name>Connector</servlet-name>
<url-pattern>/FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>SimpleUploader</servlet-name>
<url-pattern>/FCKeditor/editor/filemanager/upload/simpleuploader</url-pattern>
</servlet-mapping>
