Re: [hyades-dev] Problems with remote launch

Hi Luca,

Sorry to hear things aren't working
out well. Let's try and tackle the issues one by one..

>In external java application panel if I select the
class name with the browse button (works only if the test is on localhost)
then the class name instead to be org.test.Test.class is >filled with
Test ! 
>Not only this but automagically..  the classpath is filled with
/profile/classes/org/test/ 

This one is a known problem - see https://bugs.eclipse.org/bugs/show_bug.cgi?id=70352.
This was missed in the earlier releases of Hyades because most of the developers
were using default package samples to test. It works fine in this case
but it gets it wrong when you're specifying your own package. I've increased
the priority so that it gets quicker attention.

>I correct classname with org.test.Test and classpath
with /profile/classes/ then I start the test and it works but only
for memory profiling no coverage or method timing (and I >have they
selected). 

I've never experienced this one. Could
you give me a bit more details (please email me directly instead of posting
to the newsgroup)? Are you using the default profiling sets or creating
your own and selecting the method coverage and execution time analysis
profiling types? Can you see the profiling types under the agents in the
profiling monitor? One common error is not setting the filters correctly
- click on Edit to edit the profiling set, then click Next to see the filters.
By default, org* is filtered out.

>I'm corious to know HOW it has worked on my linux

>maybe with wine? :-||

As I understand it, it's actually not
trying to use java.exe, but is showing the application id specified in
the RAC configuration. I guess you could say this is a problem in the logging
output (it is saying that it's launching java.exe, which is not actually
true). Perhaps the RAC folks can comment on this.

Do you get any error messages in the UI, or output to
the console or .log file in eclipse? If so, this would help us determine
what is going wrong here.

>on windows is the same but in this case I get in the
console: 
>java.lang.NoClassDefFoundError: org/test/Test 
>Exception in thread "main" 

Is the /testing/profile/classes directory
at the root of the filesystem or in your home directory? We need absolute
paths here. Also, are the classes distributed in the correct directories
under this folder? One thing you might try to confirm this is launching
it from the command line while specifying the same classpath. It should
be /testing/profile/classes/org/test/<classes here>.  In general,
when experiencing problems when launching in profile mode, there's one
thing we usually try: you can start your application in profile mode manually
and attach the profiler to the VM. This is done by adding the -XrunpiAgent:server=controlled
vm argument when launching in the command line. The "controlled"
argument  tells the VM to wait until the profiler attaches until it
starts the application. Then you create a new "Attach - Java Process"
launch configuration and find the agent and process you want to attach
to.

>Note that the log of rac server on nt say that the
process is starter in  C:....\Temp. 

Yes, it currently uses the default directory that the
RAC uses. I agree that this is something we should support with External
Java Application, so I opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=76842
to track this.

>I 'm wondering how different are the behavior of rac
servers (logs are different, windows gives console feedback,..)

I'm not sure about the logs, but the console behavior
should be the same. What you see in the console is stdout and stderr -
there shouldn't be any rac output here that I'm aware of.

>I suppose hyades is developed under windows.

Although many developers use windows,
Hyades is certainly not meant to be for windows only.

>there is a configuration of the rac server log to
see what REALLY happens?? (it is aleady setted with loggingDetail="HIGH"

I'm not aware of any other mechanism to increase logging
levels - perhaps the RAC folks can help out here.

Subject	[hyades-dev] Problems with remote launch

Hi,

following problem:

package org.test;
public class Test
{
    public static void main(String[] args)
    {
        System.out.println("ok");
    }
}


the class is in 
/profile/classes/org/test/Test.class 

Hyades 3.1.0 latest release.
In external java application panel if I select the class name with the
browse button (works only if the test is on localhost) then the class name
instead to be org.test.Test.class is filled with Test ! 
Not only this but automagically..  the classpath is filled with /profile/classes/org/test/

Obvioulsy not works. 

I correct classname with org.test.Test and classpath with /profile/classes/
then I start the test and it works but only for memory profiling no coverage
or method timing (and I have they selected). 

the log on rac server say:

I'm corious to know HOW it has worked on my linux box launching java.exe
 -XrunpiAgent:server=controlled org.test.Test 
maybe with wine? :-||

now I copy the whole /profile directory on my hpux box under /testing 

I duplicate the Remote Profile configuration and substitute /profile/classes/
with /testing/profile/classes/ in classpath, and check the my remote
host. 

Not works, and again follows the log of rac server

Again, java.exe  -XrunpiAgent:server=controlled org.test.Test but
here I don't have wine installed :-))

on windows is the same but in this case I get in the console: 
java.lang.NoClassDefFoundError: org/test/Test

Here I think java.exe can work. 

Note that the log of rac server on nt say that the process is starter in
 C:....\Temp. 
I 'm wondering how different are the behavior of rac servers (logs are
different, windows gives console feedback,..)
I suppose hyades is developed under windows.

Paths of classpath on windows and hpux are doublechecked 

there is a configuration of the rac server log to see what REALLY happens??
(it is aleady setted with loggingDetail="HIGH"


NOTE:

I think that how is now, the hyades newsgroup is not usable if no one can/try
to help users.
Maybe I'm not an advanced user, maybe I'm. Anyway, if you will that other
people uses and appreciate your work, give a chance to do it! Try to help
them. Maybe they find some bugs that you will not able to discovery, or
simple gives you feedbacks on documentation and usability.
Did you make statistics on your newsgroup like how many threads haves a
reply, or in wich time it comes? Or how many threads are closed?

best regards,

Frustrated Luca (going to giving up)
