connection of java and idl at eclipse

Good morning everybody...
I need help of some experts again:D...
Which plug-in provide connection of .java files and .idl files at eclipse?
There are interface(class declarations with methods) at ".idl" file and definitions at ".java" files.
At eclipse it can't see ".idl" interface so finds some class declaration errors. To handle this situation which plugin may I use ?..
thank you in advance for your help...
