Plugins not visible

Question

Hello Guys,

Earlier i had developed a plugin for some image processing. Now I have developed a few more image processing operators and I am trying to develop a plugin for the same. I did followed exactly the same procedure which i had followed the last time. The code gets compiled properly and a jar file is also created. After copying the jar file into the plugin folder of rapidminer on starting rapidminer i dont get any kind of error but i am unable to see my operators in the rapidminer window. Could anyone plz let me the solution or where i could be going wrong?

Thanks and Regards

Thanks you guys for your help. 
Actually i am using Rapidminer version 4.0
And I found the problem. The problem was I was naming the operators.xml file as operator.xml.

But now I came to know about the this latest change and will include in my plugin

Thanks again guys.

@naharvikas:

As Steffen has pointed out: for plugins which should be combined with the latest CVS version (and also with future versions), it is necessary to add another entry in the manifest file. Please follow the instructions given in the link

http://rapid-i.com/rapidforum/index.php/topic,58.0.html

This should do the trick. A complete manifest should then look like this (taken from the Text plugin):
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 10.0-b22 (Sun Microsystems Inc.)
Implementation-Vendor: Rapid-I
Implementation-Title: Text Plugin
Implementation-URL: http://www.rapid-i.com
Implementation-Version: 4.1
RapidMiner-Version: 4.1
RapidMiner-Type: RapidMiner_Plugin

The last line (RapidMiner-Type: RapidMiner_Plugin) is new and indicates that this is a RM plugin. Just put the contents given above in a file MANIFEST.MF and place it in the META-INF folder of your jar file.

Hope that helps,
Ingo
