perfsonar development work

[Nicolas Simar <>]

Excellent suggestion! I am suggesting below a wording for the FAQ 
(please check it, I have listed few questions in [...])

(I don't know if it has to go on the perfsonar, on the wiki or on the 
wiki page for the tool) Suggestions?


Q: When installing a service and going through all the steps of the 
installation guide, when testing, I get the following error:

Error in Perfsonar.log:
2006-12-12 15:36:55,683  INFO - RequestHandler: Service received a request
2006-12-12 15:36:55,700 DEBUG - RequestHandler: Calling on parser
to parse the request
2006-12-12 15:36:56,117 DEBUG - RequestHandler: Trying to retrieve
Message object from Handler
2006-12-12 15:36:56,117  INFO - RequestHandler: Message object
constructed from request. Request is of type: MetadataKeyRequest
2006-12-12 15:36:56,120 DEBUG - MessageHandlerFactory: classname
asked for is  org.perfsonar.commons.messages.MetadataKeyReques

[Is it the proper piece of text to have to describe the error?]

A:  This error message appears
(i) when some jars (or maybe just one) are missing in Tomcat after the 
deploy operation. (the deploy operation copies a set of jars into 
Tomcat). The list Jar names you should see in [WHERE?] can be found in 
the following ANT files:
- For SQL MA: axis-deploy-targets.xml and sqlma-axis-deploy-targets.xml 
(see copy targets) [what does "see copy targets" means]
- For RRD MA: [WHICH ONES?]
(ii) or you have all jars but Tomcat wasn't restarted.
