问题 I am trying to create wso2 human task where the approval has to be given by multiple owners in some sequence. I am calling human task from Asynchronous BPEL process. I am able to upload the Process and task packages successfully. But when I try to create the process instance, i am getting below error in the logs: ERROR {org.wso2.carbon.humantask.core.integration.AxisHumanTaskMessageReceiver} - Task creation failed. java.lang.NullPointerException at org.wso2.carbon.humantask.core.dao.jpa

问题 I have a scenario where a BPEL process with a parallel flow is calling an asynchronous process in parallel and waits for their callbacks. I added two correlation sets one to correlate to the calling BPEL process instance and one to correlate to the Receive in which flow path. But I am receiving a conflictingReceive fault response. And the error: ERROR [PICK] org.apache.ode.bpel.common.FaultException: {Selector plinkInstnace= {PartnerLinkInstance partnerLinkDecl=OPartnerLink#41,scopeInstanceId

问题 I believe netbeans doesn't support BPEL. Is there a workaround for it, or can you please suggest some other IDE, where I can compose web services together? I have two web services, one which churns the data and gives the output as a JSON/string and the other web services which will have the input as the output of the previous webservice and visualize/graph the data. Thanks 回答1: Netbeans supports BPEL. For that please download Glassfish ESB (Open ESB) which includes Netbeans IDE also. You can

问题 I am creating a process in BPEL (say findRules) which has three Java Embeded Activity(A,B,C). and I have one java class(Rule.java) which I need to import on all Java Embed Activity. and when I create an instance of Rule.java A activity, can I use the same instance in B and C activity. because I am performing some business logic in A and wanted to access the updated varibles in B and C. but because B and C are having new instance I am not able to find those updated variables. 回答1: If you are

问题 I am trying to do an XSL transform on an xml structure in a bpel assignment statement. There is a syntax problem, but I am having trouble finding official documentation. There are examples all over the internet but I have not found a clear explanation. Here is my best shot. What do the last two parameters do? Why is eclipse saying the first argument must be a literal, even though test3.xsl is a string? <bpel:assign validate="yes" name="Assign"> <bpel:copy keepSrcElementName="no"> <bpel:from>

问题 Basically I want to be able to generate a response from BPEL ODE engine with complex type that has an unbounded number of elements. The idea is very basic, I get a list of objects as an input then I do some filtering based on a certain category. Then I need to generate response based on the filtering, which might be more than one elements. But the BPEL copy assignment only allow one to one assignment. I already try using array but can't seem to assign to more than one element also. The

问题 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. 回答1: 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.

问题 I need to generate BPEL XML code in runtime. The only way I can do it now is to create XML document with "bare hands" using DOM API. But there must be a framework that could ease such work incorporating some kind of object model. I guess it should look something like this: BPELProcessFactory.CreateProcess().addSequence Do you know any? 回答1: The Eclipse BPEL designer project provides an EMF model for BPEL 2.0. The generated code can be used to programmatically create BPEL code with a

问题 I have not found any documentation regarding creation of BPEL process with Human Task using WSO2 BPEL . There is just once example called Claims Approval existing which is ready to deploy process. The documentation of creating that example process was also not there. Please help me out. Have found a similar question existing but unfortunately there was no answer for that question. Any help is greatly appreciated! Greetings Karthik 回答1: Please fing documentation on at Claims Approval [1].

问题 I need to have an activity that send a mail at a certain point of the BPEL process. Is there a "mail activity" or do I have to code a sort of web services to invoke so that I call the service and let it send the mail? Could it be a solution to use the ESB for this business? How to connect the two (again with a web services or there is a quicker and easiest way to link them)? Could it be a good solution in this case to add the ESB feature to BPS to add it the transport feature without having
