问题 I have to admin the WS2 BPS (3.6.0) is not very revealing about internal exceptions. There's a small chapter in the documentation about troubleshooting, however this setup logs only messages passed to the endpoints. Questions: is there way to see internal exceptions thrown during the BPEL execution) wether handled or unhandled? (such as errors in the expressions or scripts). Maybe on the Apache-ODE level? is there any way to access the fault caught by the "catchAll" fault handler? Thank you

问题 I'd like to write a axis2 webservice for deploying BPEL Processes on a Apache ODE. At the moment I have two main issues/questions. I wrote a simple WS that creates a file. It works fine in eclipse with a integrated apache tomcat with axis2. But if I run the service on the exact same server without ecplise it won't work and I get 'Unhandled IOException' Errors, although I have the handling implemented (otherwise ecplise would cry about it all the time). EDIT: I solved it by not uploading the

问题 I need to extract the activities and their XPath of a BPEL Process out of the xml file. I'm familiar with the theory behind BPEL but not the fileformat itself. If I read a BPEL file I have difficulties to identify the specific activities. Not to speak of the XPath. How do I parse a BPEL file in a way that I get every activity, no mather what orchestration type, and its XPath? ps: in java EDIT: what I want to extract <name>CallService1Op2</name> <xpath>/process/sequence[1]/invoke[1]</xpath>

问题 My question is that: Is there any method that I can use restful web services such as Google Map or Youtube in BPEL. I know that BPEL works with SOAP web services that have WSDL file. But, I asked to do a project which should contain restful web services work with BPEL. I appreciate any hints,links and tutorials on the inetrnet. Note: I am very new to both web service and bpel concepts. I just implemented some samples from internet. I use eclipse helios, Apache Tomcat 7.0, Apache ODE server,

问题 I'm trying to create and integrate Human Task into BPEL workflow. So far I've found only one sample of human task integrated with WSO2 BPS but it doesn't show how to create it, it's just ready to deploy and execute. Does anyone know if WSO2 has recently released new tools/methods to create and integrate Human Task into BPEL? 回答1: Please refer to the following blog posts and articles they might help with your work http://nandikajayawardana.blogspot.com/2013/05/how-to-implement-your-own-task-ui

问题 I have 40 activities that do not depend on each other. I want to model them in a such way, that execution engine processes them in multiple parallel flows in any order. Execution engine may optimize their execution order (for example take as first the activity, that took the most time at the previous run). Is it possible with BPEL or BPMN 2.0? If yes - how? With a Parallel Gateway I will have to draw 40 edges, as far as I understand. Is there any better way? Thanks! 回答1: Yes, both languages

问题 I'm doing some tests for deploying business processes on WSO2 BPS. I have to make communicate multiple processes with each other (asynchronously). I made a diagram to outline the problem. Process_1 starts an instance of Process_0 and sends 2 messages with data to it. The send and the receive activities are implemented in parallel. On execution, the Process_1 will complete, but not Process_0, which will stay in an active state. The two data messages are received (they are available in the SOAP

问题 I have created WSO2 human task as per the guidelines mentioned in link (http://docs.wso2.org/display/BPS300/Writing+a+Human+Task+Artifact). I am calling human task from Asynchronous BPEL process, once human task get completed it proceeds further with other BPEL Activities and callback client. I am facing an issue i.e. Human task goes to COMPLETED task state but my BPEL Process which is calling that human task is not proceeding further from REMOTE TASK Activity to next BPEL activity and it

问题 From an answer to my previous question, I have this input XML: <?xml version="1.0" encoding="UTF-8"?> <Containers> <Container> <LocalDataContainer> <file>InputFile3</file> </LocalDataContainer> </Container> <Container> <LocalDataContainer> <file>InputFile2</file> </LocalDataContainer> </Container> <Container> <LocalDataContainer> <file>InputFile3</file> </LocalDataContainer> </Container> </Containers> Which when given to this XSLT: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet

问题 I'm using Oracle BPEL 12c to develop a process. I need to call a external service with basic authentication. I need to pass the credentials received on my exposed service endpoint to the external service. When i call, i receive this: <remoteFault xmlns="http://schemas.oracle.com/bpel/extension"> -<part name="summary"> <summary> oracle.fabric.common.FabricException: oracle.fabric.common.FabricException: Error in getting XML input stream:XXXXXX?WSDL: Server Authentication Required: Error in
