I’m trying to debug a BPEL process. I made it using BPEL Designer for Eclipse (3.7.2), i’m using Ode 1.3 as engine.
I have no idea how to debug my process. I can deploy it on ode in a debug session but I don’t really understand what can i do after that.
You can deploy BPEL processes developed in WS-BPEL 2.0 standard on WSO2 BPS server.
Once you deploy the BPEL process on WSO2 Business Process Server, you can use following mechanisms to debug/troubleshoot failures.
1.Using Message Tracer. This enables you to view the inbound and outbound messages to and from BPS server. To enable message trace logs for BPEL processes;
Add the following entries to the $CARBON-HOME/lib/log4j.properties
log4j.logger.org.apache.ode.bpel.messagetrace=TRACE log4j.logger.org.wso2.carbon.bpel.messagetrace=TRACE
The preferred log4j appender should be configured such that it has a threshold of TRACE level. If CARBON_LOGFILE is the log4j appender, it should be changed as follows. By default this is set to DEBUG.
eg – log4j.appender.CARBON_LOGFILE.threshold=TRACE
Re-start the server.
2.Using the Event table in the ‘Instance Information’ page (Figure 1). Each and every activity should have 3 events upon the successful execution. If an activity only has 2 events or if it has an “ActivityFailureEvent”, then something must have gone wrong within that particular activity. You may need to refer the log file of WSO2 BPS server in-order to further investigate on the issue.
