Dear Eugene and Navid,
Tomcat was indeed overriding my PATH
variable, therefore the agent controller was removed. It was solved by adding
the environment variable through eclipse as per your suggestions.
The Profiler now works, although it did
cause the eclipse to give an Out Of Memory error. I solved this by running
Eclipse itself with “-vmargs -Xmx512M”.
Many thanks for all your help and patience.

Hi Shiri,
You
can setup the PATH environment variable in profile Apache Tomcat server
configuration by adding an entry under the Environment tab (please see screen
capture) and points to the Integrated Agent Controller folder (ie.
eclipse/plugins/org.eclipse.hyades.execution.win32.x86_%buildID%).

Hi Navid,
Thanks for your responses. The screencast was indeed helpful.
I’ve progressed a few more steps in the right direction
– I’ve reconfigured my server to launch through WTP rather than the
original Tomcat plugin we had. The server itself works OK – not so for
the server profiler. Now, I can click on “profile” for the server
and it attempts to profile, but I get the following error message:
“Error occurred during
initialization of VM
Could
not find agent library on the library path or in the local directory:
piAgent”
This seems to be connected to the JVMPI agent that you
mentioned, but although the piAgent.dll exists in the directory, and the
directory is set as a PATH environment variable, it does not seem to pick it
up.
I also tried manually adding the JVM argument of –Xrun,
etc, but the result remained the same.
Any help would be greatly appreciated. A google search showed
me that someone else ran into this same problem back in July (with Tomcat,
specifically), and asked here, but eventually gave up…
Thanks,
-Shiri

Hi Shiri,
Here's the link to the screencast:
http://www.eclipse.org/tptp/home/documents/tutorials/viewlets/v4.1/WTP/WTP_TPTP_viewlet_viewlet_swf.html
Note that you don't need the JVMTI agent to profile on server. (i.e. You
don't need to download the New Java Profiler under the 'Technology Preview'
section). Instead you can use the JVMPI agent included with the Agent
Controller.
I agree that our download page is a bit confusing. This has been brought
up before and we're working on simplifying it.
Thanks,
Navid Mehregani

RE: [tptp-tracing-profiling-tools-dev] Problems

Hi Navid,
What screencast are you referring to? I did not receive any attachment or link.
I feel silly for asking for more help, but installing EMF/XSD did not end my
troubles with the profiler.
Now, the profiler is willing to profile simple programs, but fails when
launching the server profile on the Tomcat app.
Going back to the installations page I noticed the following plugins listed:
·
Eclipse Web
Tools Platform (WTP) 1.5.1 -
(optional) required by profile on server feature
·
Java EMF
Model (JEM) SDK 1.2 -
(optional) required by profile on server feature
However, even after installing them I get the following error message:
“The JVMTI agent org.eclipse.tptp.jvmti is not available. Make sure that
the agent’s libraries are available and that it is configured
properly.”
However, a closer look at my plugin folder shows that it indeed contains all
the jvmti client files from the zip. But these do not include an
org.eclipse.tptp.jvmti Jar, rather, it contains two other jars -
org.eclipse.tptp.platform.jvmti.client, and org.eclipse.tptp.trace.jvmti.client
. A check on the JVMTI runtime also seems to indicate that it was installed
properly in the agent controller library, as specified.
Phew! Definitely makes me want to get the aforementioned update manager, as
Harm suggested. (Any handy links?)
Thanks once again,
-Shiri

Hi Shiri,
Here's what you need to profile a tomcat server app:
- Under 'TPTP Runtime and SDK' section, download TPTP runtime (All)
[Looks like you already downloaded this]
- Under 'Agent Controller' or 'New technology Agent Controller' section,
download the Agent Controller for Windows IA32 [Looks like you already
downloaded this]
- Under 'Requirements' section, you'll need both Eclipse SDK 3.2.0 and EMF and
XSD packages. [You probably already have Eclipse SDK 3.2.0, I'm not sure
about EMF and XSD though]
> Possible reasons include the duplicity of the agent controller files
– as I mentioned, a close look at the downloads page shows that both old
and new agent controllers point to the same zip file.
Yes, the new Agent Controller replaced the old one for Windows IA32. This
is why their links are the same.
Here's a screencast that gives an introductory overview of how you can profile
a tomcat server application.

Navid Mehregani

[tptp-tracing-profiling-tools-dev] Problems with
Profiler installation
|
|
Hi,
I’m trying to run the Java Profiler in my Eclipse environment (v3.2) to
profile a tomcat server app. I have a WinXP machine.
I’ve followed the instructions on these pages:
http://www.eclipse.org/tptp/platform/documents/tutorials/jvmti/Java_Application_Profiling_using_TPTP-v2.0.html
http://www.eclipse.org/tptp/home/downloads/installguide/agentcontroller_42/win_ia32/getting_started.html
Starting from the TPTP 4.2.0.2 installation page
(http://www.eclipse.org/tptp/home/downloads/drops/TPTP-4.2.0.2.html), I
installed the following components:
-TPTP runtime (“All”)
-New technology Agent Controller (which, for an unexplained reason,
points to the same file as the “old” agent controller). Also ran
the batch file as specified.
-JVMTI client
-JVMTI runtime – in the agent controller folder, as specified.
I also manage to run the agent controller from the command line.
However, when it came to configuring the profiler inside eclipse, I got in
trouble – my preferences do not show a “Profiling and
Logging” option as described on the Profiling page (http://www.eclipse.org/tptp/platform/documents/tutorials/jvmti/Java_Application_Profiling_using_TPTP-v2.0.html).
Possible reasons include the duplicity of the agent controller files – as
I mentioned, a close look at the downloads page shows that both old and new
agent controllers point to the same zip file.
Also, I got a slightly odd log message (included below) in AC, though I’m
not sure if it related.
Any clue on how to get this running would be greatly appreciated.
Thanks,
-Shiri
