Eclipse Profiler Plugin

Was looking for eclipse profile plugin and got this link: http://eclipsecolorer.sourceforge.net/index_profiler.html
Download link is here.

I could not get the plugin working with eclipse-3.2 but I could see the Profiler perspective as described when I tried with eclipse-3.1.

When I tried to run the profiler I got some error like this:
Plug-in unable to load class ru.nlmk.eclipse.profiler was unable to load class
ru.nlmk.eclipse.profiler.launch.ProfilerLaunchConfigurationDelegate.

Check out more discussion on this problem here.

I tried to use the bug fixed plugin for eclipse-3.1, use this link.

After getting this patched version of plugin:
1. Unzip it to eclipse/plugin folder.
2. For windows:
Copy ProfilerDLL.dll to ${JAVA_HOME}/jre/bin folder

For Linux Box:
Get libProfilerDLL.so from native/profiler_linux.tgz and copy it to libProfilerDLL.so in native/profiler_linux.tgz to ${JAVA_HOME}/jre/lib/i386/

[NOTE] I had to recompile a new version of libProfilerDLL.so. Its simple to do. Just set the right path for your java installation in the shell script m [you get it after untaring native/profiler_linux.tgz], execute it (you will need right permission to copy the shared library)

Shell script m (used to recompile and copy libProfilerDLL.so)
#!/bin/sh
export JAVA_HOME=/usr/java/j2sdk1.4.2_06

g++ -O0 -DLINUX -shared -Wall -I. -I${JAVA_HOME}/include -I${JAVA_HOME}/include/linux ProfilerDLL.cpp -o libProfilerDLL.so
cp libProfilerDLL.so ${JAVA_HOME}/jre/lib/i386/libProfilerDLL.so

Enjoy Profiling!

hi there, I also stumbled upon this profiler which looked promising, however I have trouble installing it on my ubuntu box. I have eclipse 3.2, tried with both the patched and the nonpatched versions of the plugin, for both I compiled the .so but I get an error when I want to create an instance of the profiler in the run menu. Yes I see all the new perspectives but I cannot use them, here is the error:
