perfSONAR User Q&A and Other Discussion

[Rodrigo Dlugokenski <>]

Maybe it's this, because I finished all configurations, and when I access the service (http://server:8180/perfsonar-java-sshtelnet-mp/services/TelnetSSH) for the basic test, I got this error msg:

The service cannot be found for the endpoint reference (EPR) /perfsonar-java-sshtelnet-mp/services/TelnetSSH

Comparing the md5sum from common lib files of the 2 releases, the md5 are not the same.

I installed the 1.3.4.2 deb and works fine.

After all, thank you for your attention.

For now I'll test the 1.3, but is more painful to configure than 1.4. Congrats for simplifying in the new release.

Yep, and the md5sum is exactly the same. BUT, the big but, is the libs md5
that are not the same.

I tested the debs, and extracted the tar.gzs from inside the debs and tested
again. The tools i've used returned nothing wrong.

Maybe something wrong with the .deb from 1.4? I redownloaded again, and I
had the same results.

Hmm, I think you're probably right. The fastest way to solve this issue would be to generate the new release candidate package of the service.
I will let you know when the new package will be available in the repository.
Thank you for spotting this issue.

Best regards
Blazej

 Looks like it is some regression.
   

I can run the SSHTELNET_configurator.jar from* **
perfsonar-java-sshtelnet-mp_1.3.4.2_all.deb* just fine.




     

That's weird, because nothing has changed in the configurator since that
release.

Best regards
Blazej

I'm thinking if is not another requisite, a indirect one (ex: jdom needs
another libs?)

Thanks for the quick response!

 Hi all!


         

I'm trying to deploy the telnet/ssh mp, and the service is running fine
in
tomcat.

But my problem is with the SSHTELNET_configurator.jar. When I try to
run
it
quits with message below:

arch-mp1 Configuration_Tool # java -jar SSHTELNET_configurator.jar
sshtelnet.xml
Exception in thread "main" java.lang.NoClassDefFoundError:
org/jdom/IllegalAddException

Trying to "fix" I installed JDOM and Jakarta-Commons libs, but no luck.

Is some another prerequisite that I don't have in my java enviroment?

My system:
ArchLinux
Java JDK +JRE 1.6u20
eXist db 1.2.6
Tomcat 5.5

I have the very same system for other services I already deployed, like
RRD,
SQL, etc, and they're working as expected.
I tried the path with Ubuntu 8 and CentOS 5, but i've found much more
difficult to deploy than with archlinux, I bet that in Ubuntu/CentOS
the
prerequisites are installed all automatically, even the indirect ones,
right?

Thanks for your attention,
Rodrigo

Hi Rodrigo,

Thanks for using SSH/Telnet MP service.
It looks like the libraries that are used by the Configuration Tool are
not found by the JVM. Those libraries are installed together with the
Configuration Tool under the Configuration_Tool/lib directory. At first
I
thought that it is a problem with the working directory path, but it
looks
like it is something else. No matter what working directory I choose it
works on both Ubuntu and CentOS.

In order to solve the problem I need help from your side.
Could you answer to the questions provided below, please?

1. What's under the Configuration_Tool/lib directory (ie. run "ls -al
Configuration_Tool/lib" command)?
2. What's the output of the "java -version" command?
3. Could you provide those libraries in the classpath ie. run the
command
below:
"java -cp
lib/commons-logging-1.0.4.jar:lib/jdom-1.0b8.jar:lib/wss4j-1.5.1.jar
-jar
SSHTELNET_configurator.jar sshtelnet.xml".
Does it work for you?
4. Which package version have you used (e.g. 1.4RC2)?
5. Is it DEB or RPM package?

Best regards
Blazej
