Hi all,

I use my own content assist and want to use methods in class files. Is
there a possibility to convert in eclise the binary code in java source
code?

Thanks!

Artur,

I'm pretty sure such a thing isn't built in. If you don't have the
source code for something (you can specify source attachments for jars),
you probably aren't meant to have it...

You can try using a decompiler, such as JAD. There is a plug-in for
JAD, called JADClipse, that will let you view .class files as Java
source, with some limitations.

As Ed suggests, you need to be careful of licensing issues; it is not
always legal to decompile binaries.

Sure that there is no way?
I tried it with
org.eclipse.jdt.internal.compiler.classfmt.ClassFileReader, but i only get
the method names.
I can't find a way to get the method body.

Thanks!
I'm workin on a project which should make it possible to reuse code that a
user already implemented. So there aren't problems with the license. I'm
searching for a way to get the source code without any decompiler. My
problem is, that i have to use eclipse for that, without any usage of
other tools.

Thanks!

Artur,

Making use of source attachments (a jar/zip file with all the
corresponding sources) is the way to go then.
