Error profiling Tomcat: JPIAgent can't load ACCollector [message #115504] Mon, 15 October 2007 13:07 Go to next message

Originally posted by: dittrich.alternate.de

Hi there,

when I try to profile a tomcat application with TPTP I get
the folliwing error message:

[Error: FATAL ERROR: JPIAgent can't load ACCollector]

and tomcat doesn't start.

I searched this list and found another posting about this by
Jim O'Neill - but his solution is not working for me.

I have installed and configured absolutely fresh copies of:

jdk-6u3-linux-i586.bin
apache-tomcat-6.0.14.tar.gz

eclipse-SDK-3.3.1-linux-gtk.tar.gz
wtp-R-2.0.1-20070926042742.zip
birt-report-framework-2_2_1.zip
dtp-sdk_1.5.1.zip
emf-sdo-xsd-SDK-2.3.1.zip
GEF-SDK-3.3.1.zip
tptp.runtime-TPTP-4.4.0.3.zip

Also I started with an empty workspace to make sure no
outdated versions of whatever hang around. I never had any
other TPTP version or so installed.

I configured the tomcat in
Window-Preferences-Server-Runtimes and created a web app to
launch with it. The server starts in normal and debugging
mode without problems.

But when I try to start the server in profiling mode, I get
to choose the profiling options (Execution time analysis
etc.) and after that tomcat fails to start with the error
message above.

Can anyone please help me with this problem?

Many thanks in advance
TD

The error message suggest that the libACCollector.so library is not
specified in the LD_LIBRARY_PATH environment variable. I am quite sure
that this should be configured automatically by the IAC, but you may
want to try to configure this yourself. This file should be located in

eclipse/plugins/org.eclipse.tptp.platform.jvmti.runtime_<version >/agent_files/linux_<architecture>

HTH,
Asaf

I found an email from you about this problem and following
your instructions I have set up the following environment
before starting eclipse:

JAVA_PROFILER_HOME=/usr/local/eclipse/plugins/org.eclipse.tp tp.platform.jvmti.runtime_4.4.1.v200709261752/agent_files/li nux_ia32

TPTP_AC_HOME=/usr/local/eclipse/plugins/org.eclipse.tptp.pla tform.ac.linux_ia32_4.4.1.v200709261752/agent_controller

libJPIBootLoader.so is both in LD_LIBRARY_PATH and
JAVA_PROFILER_HOME...

I'm still very clueless :(

Please check that libJPIBootLoader (et al) are also in the system path
(PATH).

Also, can you please post the Java version you're using (use java -version)?

Thanks,

I made my PATH look like this:
PATH=$JAVA_PROFILER_HOME:$TPTP_AC_HOME/bin:$PATH

Still the same error message :(

My Java version:
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode,
sharing)

This is the one and only jdk installed on my system, I
removed all other java versions to make sure no old version
gets in the way.

Thanks for your patience, Asaf.

Tobias,

> Thanks for your patience, Asaf.

I should thank you. Don't give up on us :)

Can you please enable logging by doing the following and post the
resulting log file to the newsgroup?

To enable logging, define the following environment variables before
starting Tomcat:

export MARTINI_LOGGER_DIRECTORY=<path to an existing directory, e.g.,
/tmp/log))
export MARTINI_LOGGER_LOG_LEVEL=5

Thanks,
Asaf

No way :) This is a really cool piece of software, I'm
longing to see it in action and use all the promising
features :)

Actually this was one of the first things I've tried to find
out what is going wrong. Unfortunately without any result -
no log file is created at all.

I thought this was due to the fact that the error says:
"Error occurred during initialization of VM". The VM is not
started at all, so the logger has no chance to do anything.
But I might be wrong.

Anyway I retried with the same result: no log file created :(

Always nice to get some positive feedback :)

The "error occurred..." error message is quite generic. It indicates
that the JVM has failed to successfully load and initialize the specific
JVMTI agent (the JVMTI Profiler runtime in our case). The fact that no
log file is created suggests that the JVM was simply not able to load
libJPIBootLoader.so.

This failure can be caused by any of the following reasons:
1. libJPIBootLoader.so does not appear in LD_LIBRARY_PATH and PATH. We
know this is not the case with your environment.

2. libJPIBootLoader.so is incompatible with your Linux environment/JVM
and therefore cannot be loaded by the JVM (or maybe the file is corrupted?)

To check the latter, please provide the following information (make sure
to execute the commands after setting the correct environment for
running Tomcat):

- output of "uname -a"

- output of "file $JAVA_PROFILER_HOME/libJPIBootLoader.so"

- output of "file $JAVA_HOME/bin/java"

- output of "ld -d -r $JAVA_PROFILER_HOME/libJPI.so"


Thanks,
Asaf

Just to let you know that I'm experiencing exactly the same problem as
Tobias describes. I'm using the

Tobias,

Have you tried using the standalone Agent Controller instead of IAC?

Hi All,
I'm using standalone Agent, I've tried the 4.4.1, 4.5.0 version on
linux-ia32

I have the same error :
Error: FATAL ERROR: JPIAgent can't load ACCollector.

The ACCollector.so is visible in the LD_LIBRARY_PATH and the PATH and
all dependencies seems to be ok.

Tobias, did you found a solution for your issue ?

Asaf, any suggestions ? which version of the AC has been successfully
used under linux ?

thank by advance for you help and contribution to this great tool.

Regards,
Anis

Hi all,
could you please at least give me the last version successfully used and
tested under Red Hat Enterprise Linux 4.4 ?

I'm very disappointed. I hoped using TPTP in my project (since I'm
eclipse rcp developper), however, this serious and unsolved issue is
blocking me. I have no idea about the problem evoqued below.

Any news, suggestion is welcome !

Regards,
Anis

Re: Error profiling Tomcat: JPIAgent can't load ACCollector [message #123532 is a reply to message #117572] Wed, 20 February 2008 14:13 Go to previous messageGo to next message

Hi,

I am using eclipse and likewise, I believe it is a fabulous product but I
suffer from this very issue and when I get to this point I get the
following results:

kirber@kirk:~$ ldd -d -r $JAVA_PROFILER_HOME/libJPI.so
not a dynamic executable

All of the previous variables seem to work the same as Tobias' with the
exception of this one!

I would appreciate any feedback possible. I am new to Eclipse, TPTP and
Linux(Ubuntu).

Thanks in advance

TPTP runtime launches tomcat with a command line similar to:

-agentlib:JPIBootLoader=JPIAgent:server=enabled;CGProf:execd etails=true
....snip... org.apache.catalina.startup.Bootstrap start

Try it in a shell for any testcase and it will fail with the same error
- can't init JPIBootLoader.

I think the fix is trivial although I'm not sure you can do it without
rebuilding tptp runtime - just add quotes for -agentlib or escape ';', i.e.

" -agentlib:JPIBootLoader=JPIAgent:server=enabled;CGProf:execd etails=true "

I run it on ubuntu.
