MyEclipse is not going to support this if the project was compiled without debugging information, unfortunately it has no way to map the information it gets back from the server to source lines in your project. I suppose you could try blindly stepping in the code (if that even works, you would need to be able to hit a break point first which I’m not sure will work) and seeing what the debugger says is the current line is, then looking at your decompiled version to see which line that maps to… which again may not be accurate because of the lack of comments.
