Hi,
I'm using a logging and a statistical agent to get data of predefined Web
Services with a JAX-RPC handler within Axis (using Eclipse WTP with Tomcat).
The collected information is gainable via AgentController (NewTec ACServer
4.2). When connecting to the AgentController via an extended version of
org.eclipse.tptp.platform.execution.samples.SampleClientAC (using
org.eclipse.tptp.platform.execution.client.agent.IAgent instead of
org.eclipse.tptp.platform.execution.client.agent.ICollector) all works fine.
But when I'm stopping the extended ClientAC and try to reattach to an agent
I can query the names of agents, but during monitoring the agent I get no
more data (e.g. CBE from the logging agent). To get worse ... after stopping
(or trying to reattach) both agents, Tomcat shuts down.
Any ideas to (at least) avoid Tomcat shutting down?
Thanks in advance,
Martin
(Eclipse 3.2.0 and TPTP 4.2)

I've just added additional code to store specific data from CBE's in a
database.

Szenario 1: I start Tomcat and AC and connect from extended SampleAgentAC to
logging agent
(((IAgent)TCollector).startMonitoring(TPTPDataPath.DATA_PATH _TWO_WAY);) and
from an Eclipse-platform to statistical agent. When I disconnect statistical
(via "pause monitoring") and logging
(((IAgent)TCollector).stopMonitoring();) agents Tomcat shuts down.
Szenario 2: I start Tomcat and AC and connect from extended SampleAgentAC to
logging agent and from an Eclipse-platform to statistical agent. When I
start monitoring the statistical agent I'm able to arbitraily sart/stop
monitoring the logging agent (as long as I'm not stopping the client
program) ... when I'm stopping the client program it is possible to query
the AC for agents (and I'm getting all agents), but I cannot start
monitoring them (in this case the logging agent). If I now disconnect from
statistical agent Tomcat shuts down again.

I can not find any problems here ... AC works fine.
> Are these the agents developed by you or the standard TPTP agents?
Logging agent (section from JAX-RPC-handler):
LoggingAgent loggingAgent = new LoggingAgent("loggingAgent");
.... (create and fill cbe)
cbe.validate();
loggingAgent.write(EventFormatter.toCanonicalXMLString(cbe, false));
Statisitcal agent (starting as own thread) is similar to
DemoStatisticalAgent (eclipsecon.tutorial.demo.agents) from
http://www.eclipse.org/tptp/home/documents/conferences/eclip seCon2006/EclipseCon_2006_Tutorial_22_Source_Code_Paul_Slaue nwhite.zip

If you release the agent from the first client program, yes, you can attach
to the same agent instance from another client if it is still available.
Looks like you are having problem when both the agents are running
simultaneously. Do you see the same problem if you operate these agents
independently (I mean just try to run one agent at a time and issue commands
only to that agent from a client program)?
Thanks

There's no problem with the reattachment of the statistical agent (which =

logging agent (via the client program) ... first I'm querying for =
running agents (... get the logging agent ...) and then I attach to =
logging agent (and start monitoring:=20
< =
(IAgent)agentCollector).startMonitoring(TPTPDataPath.DATA_PA TH_RECEIVE); =
>.
There are no exceptions, but=20
< (IAgent)agentCollector).addDataListener( new IDataProcessor() { ... =
public synchronized void incomingData() ...} >
(here I'm converting the received CBE's) is not invoked any more.
Running (and attaching) to the agents separately or simultaneously makes =
no difference!
Many thanks!

Martin,
My guess is that either the data channel from the first session didn't =
get closed properly or the logging agent didn't get released from the =
first session. I tried similar steps but was not able to reproduce the =
problem. Can you please list the code (if it is fine with you) in the =
client program related to few steps involving the steps - agent =
creation, data path establishment and agent release, etc? Can you also =
please debug and find out after which step it fails or hangs during the =
second run? Do you see any error messages in the AC log file (run AC =
with logging set to DEBUG mode)?
Thanks
Vishnu
