java integration

Hello.
After working with web.xml, pom.xml e jar files, i could initialize the ConnectorServlet succesfully:
Here is the output:

0 [main] INFO net.fckeditor.handlers.PropertiesLoader - User's properties loaded successfully!
16 [main] INFO net.fckeditor.connector.ConnectorServlet - ConnectorServlet successful initialized!

But I still cannot upload/browse images in the server. I am getting a 404 error (not found) on editor/filemanager/connectors/java/connector.java

Looking into folder connectors, there is no java, only these:
/asp
/aspx
/cfm
/lasso
/perl
/php
/py

And in the fckconfig.js there is no option for java in these variables:
var _FileBrowserLanguage = 'java' ; // asp | aspx | cfm | lasso | perl | php | py
var _QuickUploadLanguage = 'java' ; // asp | aspx | cfm | lasso | perl | php | py

I am trying FCKeditor 2.6.1 and fckeditor-java-core-2.4-beta-1.jar

What I am missing?
