perfSONAR User Q&A and Other Discussion

[Rodrigo Dlugokenski <>]

I know about the url changes, I installed all the system by hand, by myself, and VERY carefully. ;D ;D

From various jars that you can download easily on internet, most doesn't matched the md5s.

I will work on this again in the next week, and I'll try again the 1.4, even trying to download from another ISP.

Have a nice weekend ;D

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.
 

From 1.4 release the urls have changed from "ps-mdm-sshtelnet-mp" to "perfsonar-java-sshtelnet-mp", so that is the reason why you cannot access the service.
If I may suggest anything it would be better if you use the 1.4 release since it fixes some bugs from 1.3.4.2 release.
The metadata file that you created could be used in 1.4 release as well.

Best regards
Blazej

 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
Caused by: java.lang.ClassNotFoundException:
org.jdom.IllegalAddException

    at java.lang.ClassLoader.loadClass(ClassLoader.java:307)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: ServicePropertiesConfigurator. Program
will
exit.

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
