IWAT0003E/IWAT0004W when profiling HelloWorld class [message #44698]

Hello everyone,

I'm taking my first steps with TPTP 4.1 and like to do without a
seperate Remote Agent Controller.

I have written a simple HelloWorld class and like to profile this class.

Each time I invoke profiling using "Profile as.../Java Application" I
get the following message:

IWAT0003E Launch Java Process Error
IWAT0004W Problems occurred while launching the Java process.
Reason:
Profiler unable to establish connection with RAC. Possible fix: Add more
memory or reduce dataChannelSize in serviceconfig.xml.

I take it RAC means Remote Agent Controller? I do not know where I have
a remote controller configured? How can I switch to local profiling only?

I have already removed all hosts from Preferences/Profiling and
Logging/Hosts, apart von "Local Direct Connection".

In my DefaultMonitor (ProfileProject), every time a host with the name
of my machine is created (port -1!). Shouldn't that read something like
"Local Direct Connection" instead, without using any ports?

Also, one of the tutorials talks about perfect integration with WTP 1.0.
As WTP 1.0 is not released yet, which of the current integration builds
would be best to test that perfect integration?

Regards,

Andreas

Hi Andreas,

I just tried profiling a simple HelloWorld class using the local direct
connection in 4.1 and it seems to be working fine. Can you try launching
your application using the external launch configuration? Click on the
profile button -> Profile... -> Create a new 'External Java Application'
launch configuration -> Select 'Local Direct Connection' under Host ->
Switch to the main tab -> click on browse and select a HelloWorld class ->
click on the Profile button. See if you still have the same problem. Make
sure you have downloaded the release build posted on our site. TPTP also
doesn't support Java 5 so make sure you're using JDK 1.4.

TPTP 4.1 doesn't support Java5? I can't believe it...

If this is true, there is no point in continuing any further; I have
been using JDK 1.5 for about a year and will never go back.

Strangely, I could get TPTP 4.0 working with JDK 1.5 (using the supplied
Agent Controller). How can that be?

Andreas

TPTP4.1 doesn't officially support Java 5. The Agent Controller and the
profiling agent could still work in Java 5, but we don't officially
support it. Java 5 will most likely be supported for 4.2. There are also
plans for including a JVMTI agent in 4.2. (JVMTI is the replacement for
JVMPI in Java 5).

I decided to give it another try. Following your instructions, I get
exactly the same error message.

I have downloaded and installed the TPTP 4.1 release.

Regarding the JDK: Eclipse is running with J2SE 5.0, I can't change
that. The project in question is switched to JDK 1.4 compliance in the
Compiler settings and includes the JRE 1.4 System Library in the
Classpath. Is this enough to satisfy the need of TPTP for JDK 1.4?

Andreas

Andreas,

I just profiled a simple class using IAC with Java 5 and it seems to work
fine. It's really strange for it to be looking for the RAC when you're
using IAC to profile. At this point I can only think of two things that
can be wrong: 1) the plugins were not installed properly and there are
traces of the old code 2) There could be something wrong with your
environment. You mentioned that you grabbed the latest build so I'll
assume it's not #1. Try out the following:

- Open a new command prompt
- Clear your PATH environment variable (i.e. set PATH="")
- Go to the Eclipse directory
- Start eclipse from the command prompt using the following command: java
-classpath startup.jar org.eclipse.core.launcher.Main
- Select an External Java launch configuration
- Select Local Direct Connection, click on 'Test Connection'. Tell me what
you get
- Hopefully you get a connection success message at this point. Try
profiling your class now.

IAC uses the JDK specified for the workbench so if it has any problems
with Java 5, the above will not fix it. However, as I've stated above, I
did try profiling a simple java app with IAC using Java 5 and it seems to
be working fine.

I followed your instructions. I'm getting a connection success message,
but still the error box.

Regarding old code: I upgraded from TPTP 4.0. Unfortunately, due to an
Eclipse bug it is not possible to uninstall the old version (you can
disable but not uninstall). I deleted every TPTP 4.0 plugin/feature
manually.

Regards,

Andreas

Andreas,

To me this sound like a problem with your environment or the way you've
set up TPTP. Unfortunately, it's really hard for me to say what the
problem is when I don't have access to your machine. At this point, I can
only suggest that you get a clean install of the workbench and TPTP.

If anyone else have any suggestions, please jump in.
