Can someone point me in the right direction?

"on the library path" ... are you using Linux? If so, do you have your
LD_LIBRARY_PATH set to the <RAC_installation_directory>/lib?? For
Windows it would look for piAgent.dll, and that would be in the
<RAC_installation_directory>/bin with the other executables; in Linux
the libs go in the ../lib area, and LD_LIBRARY_PATH is required to find
libpiAgent.so.
If this doesn't help, tell me Platform/OS, and which of the two sites
you got the find/install tool to update from (one is the "standard
Eclipse site" under some name... the one you *want* is the Callisto
Discovery site, as 3.2RC7 is a Callisto development release).

I'm using Sun's JDK 1.6 beta on Linux and I grabbed TDTD from the Callisto
Discovery site. The libpiAgent.so file is in:
eclipse/plugins/org.eclipse.hyades.execution.linux.x86_4.2.0 .v200606131519
I've added this to the LD_LIBRARY_PATH and am still getting the same
results.
Thanks for your help!

Sorry, I'm used to using the agent controller via the separate package
(connecting to the "RAC" via localhost:10002), not as used to the IAC
(integrated agent controller... going through "local direct
connection"). Hmmm, the IAC shouldn't require the LD_LIBRARY_PATH I
didn't think. It "knows" where its agents are!
That makes me think it's the Java 1.6... I think 1.6 is JVMTI-only, and
piAgent is a JVMPI agent. If you're bound to Java 1.6, you'll probably
want to get the JVMTI tech preview (< http://www.eclipse.org/tptp >) =>
Downloads => 4.2.0 => scroll down and find the JVMTI tech preview. If
you can go to Java 1.5 instead, what you have should work.

Well, I reverted to Java 1.5 and freshly installed Eclipse 3.2RC7 with
tptp via the install/update tool. It seems like Eclipse is still giving
me the error:
Error occurred during initialization of VM
Could not find agent library on the library path or in the local
directory: piAgent
Is there anything else that I should try?
Thanks again.

Here's another update. I downloaded the RAC to try starting the agent
directly. When I tried to do this, it gave me an error indicating that
libstdc++-6.2 was missing. I corrected this and have been able to run the
agent and the profiler under Java 1.5. With Java 1.6, I am getting the
following error:
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:620)

This is with the "New Java Profiler" installed (with JVMTI).
While it is encouraging that the profiler is now working with 1.5, I would
be really happy if I could get it to work with 1.6.

You're sure the Eclipse is "seeing" the 1.5 JVM, right?
You're on Linux, but what platform? If we're dealing with Intel IA32,
I'm terribly confused as to what is wrong. If you're on a 64-bit
platform, then we're seeing a mismatch in libraries due to support not
being there!

Jason,
The current TPTP Profiler supports what is the JVMPI interface.
This JVMPI interface is not supported in Java 1.6, it is supported for
compatibility in Java 1.5.
Java 1.5 and 1.6 have a new interface for profiling and is called JVMTI.
The "New Java Profiler" offered as a technology preview supports the
JVMTI interface and has been validated against Java 1.5 based VM's. The
new java profiler has not been validated against Java 1.6 - we plan on
validating the New Java profiler in the upcoming releases.
