I have flash builder 4.6 and eclipse indigo installed seperately on my window pc.I want to run java code in either flash builder or run flex code in eclipse indigo.Could i use flash builder files to include in eclipse as plugins or use eclipse file in flash builder to fulfill my need.
Either works. Flash Builder 4.6 is built on Eclipse Indigo 32-bit, and there's a utility to install the FB plug-in to an existing Eclipse 32-bit installation (in the Flash Builder's utities directory, Adobe Flash Builder 4.6 Plug-in Utility.exe). So, either add the Java plugins to FB, or run the util to plug into Eclipse. Myself, I ran the utility to plug into an existing Eclipse J2EE installation.
