error in jopr console

[jbosstcs]

Hi there,
I have 2 queries...

1.)I am using jopr server and agent on my windows machine. I have
jboss service running on my machine which is detected by the server and
shown in the dashboard ( i have imported the resources ). However when I click on a managed resource like a machine or a server or a service to see it's health I get an exception thrown in the logs. The stack trace is attached.
I am running win xp SP2 , and jopr server and agent 2.1.0... jdk
and jre 1.5... jboss 4.2.3 GA
What am I missing here ?

2.) Do I necessarily need to use jboss AS plugin for jopr ?

thanks a lot in advance for the time and help

First, you do not have to use the jboss plugin. I mentioned this earlier in another forum thread, the ONLY plugin you are required to use is the platform plugin. All the others are optional. You only need them if you want to manage the servers those plugins handle - if you do not want to manage JBossAS instances, you don't need the jboss plugin.

There is no way to remove plugins from the system if they have already been deployed (search this forum for the related thread on this - we recently discussed this).

But, if you know you do not want to use the jboss plugin, then after you unzip the distribution, but before you run the server, go into jbossas/server/default/deploy/rhq.ear(.rej)/rhq-downloads/rhq-plugins and remove those plugins you do not want to use. Again, remember you must use the platform plugin - that one is required.

As for this exception, I don't know what's going on. We're getting some people saying they see NoClassDefFoundExceptions - which I can't explain. I wonder if something is wrong with the download site and its corrupting the downloads. Someone on an earlier thread said they redownloaded the distribution and the class-def errors went away.

[jbosstcs]

thanks Mazz for your help... sorry for not seeing the discussion regarding the plugin removal... i have now seen that thread...
as you said, i too think that the download was probably corrupt because of which that class went missing.... i will re-download and see...
one last question i have is that is the jboss AS plugin which comes bundled with jopr 2.1 compliant with jboss 4.2.3 GA ?

thanks again for your help...

[mazz]

Yes, the jboss plugin will work with JBossAS 4.2.3.

Let us know if your download was corrupted - if it turns out it was, we need to figure out what's wrong with the download site.

[jbosstcs]

ya sure i will let you know... but before that i want to confirm that i need to re download the jopr server and not the agent... right ?

[mazz]

Yeah, this is a problem in the server - you want to download that.

[jbosstcs]

before proceeding for a fresh download i just checked my present one and i do find that class which is not being found, in the server... ( at this path
$JOPR_SERVER_HOME\jbossas\server\default\deploy\rhq.ear.rej\rhq-portal.war\WEB-INF\classes\org\rhq\enterprise\gui\legacy\action\resource\common\monitor\visibility)...
do i still go for a fresh download or is the problem somewhere else ?

[mazz]

In "rhq.ear.rej" ???

That rhq.ear.rej should not be there. After you ran the installer webapp, that should have been renamed to rhq.ear.

Do you have two ears in here??? rhq.ear and rhq.ear.rej?

[mazz]

I suspect your install is corrupted somehow. You should have not have a rhq.ear.rej at all if you were able to access the main Jopr UI.

I would uninstall and re-install.

[jbosstcs]

oh... sorry for the confusion... i am currently hooked onto my personal laptop on which i just downloaded the server and agent but haven't installed them... that is why, as you said, it remains .rej... i have installed them on my office pc... but yes i did find one thing... i tried to open that class file with a decompiler and it gave a class corrupt error... could that be the culprit ?
anyways i will confirm the ear part tomorrow from office as well as probably re-download the server....
after downloading the server can i just replace those class files instead of reinstalling the server from scratch ?...
and yes thanks a lot for your help ...

What version of Java are you using?

We only support 1.5 and 1.6. If you have 1.4, that's no good.

Is it a SUN VM or another vendor?

[mazz]

FYI: I just downloaded the binaries and ran them - things work OK here.

[jbosstcs]

i am using java 1.5 and it is the sun jvm... let me re-download the server binaries and see if i can go ahead w/o problems...

[jbosstcs]

found the problem... what happened was that the names of some classes got truncated leading to them not being found... like the one in the stacktrace i attached and others too... this could probably have happened during installation of the server... anyways i renamed them correctly and now the noclassdef error has gone... thanks mazz for your help...

[mazz]

Argh! Are you on Windows?! We've seen this kind of thing. Sorry I didn't think of it earlier.

We even document this in our install docs :-}

In the big red box:

https://docs.jbosson.redhat.com/confluence/display/JON2/d.+JON+Server+Installation+Guide

"Windows Installation

On Windows, do not install the JON Server into a directory with a path longer than 19 characters (e.g. use C:\Program Files\ rather than C:\Documents and Settings\myusername\ ). Excessively long pathnames may result, causing errors during execution of the server."
