Com.bea.bpm.papiws.OperationException_Exception: Invalid comparator

Question

Hi,
I am using my studio papi wsdl - http://localhost:8585/papiws/PapiWebServiceEndpoint?wsdl,
and using interface PapiWebService i am trying to abort the instances
for a particular process with a filter condition i.e. customer id as '111000'
I am getting below said exception:
com.bea.bpm.papiws.OperationException_Exception: Invalid comparator

     at com.sun.xml.ws.client.sei.SEIStub.invoke(SEIStub.java:118)
     at $Proxy27.processesGetInstancesByFilter(Unknown Source)
its working fine when create instances using 'processCreateInstance' of PapiWebService interface but when i am trying to 'processesGetInstancesByFilter' of PapiWebService interface its failing.
Any thing I am missing in this?

Answer 1

I was able to rectify the exception by pointing to dev papi wsdl instead of local studio papi wsdl.
However I have a small issue.
Below is the java code where in I am passing the processid and filter params -
          ProcessIdSetBean processidBean = new ProcessIdSetBean();
          processidBean.getProcessIds().add(_processId); // Process Id being set
          SearchScopeBean searchScopeBean = new SearchScopeBean();
          FilterBean filterBean = new FilterBean();
          String variableId = "";
          String variableValue = "";
          if((null != filterParams )&&(filterParams.size() > 0 )){
               for (Iterator iterator = _filterParams.keySet().iterator(); iterator.hasNext();) {
               FilterAttributeBean fltrAttributeBn = new FilterAttributeBean();
               fltrAttributeBn.setComparison(Comparison.CONTAINS);
               variableId = (String)iterator.next().toString();
               fltrAttributeBn.setVariableId(variableId.trim());
               variableValue = (String)_filterParams.get(variableId).toString();
               fltrAttributeBn.setValue(variableValue.trim());
               filterBean.getAttributes().add(fltrAttributeBn);
          searchScopeBean.setStatusScope(StatusScope.ONLY_INPROCESS);
          searchScopeBean.setParticipantScope(ParticipantScope.ALL);
          filterBean.setIsMatchAll(true);
          filterBean.setSearchScope(searchScopeBean);
          InstanceInfoBeanList instanceinfoBeanList;
          List<InstanceInfoBean> instances = new ArrayList<InstanceInfoBean>();
          try {
               //instanceinfoBeanList = papiWebServicePort.processesGetInstancesByFilter(processidBean, filterBean);
// instanceinfoBeanList = papiWebServicePort.processGetInstances(_processId);
          } catch (OperationException_Exception e1) {
               e1.printStackTrace();
I am able to retrieve all the instances for a process id by using 'instanceinfoBeanList = papiWebServicePort.processGetInstances(_processId);' but when I am giving filters and retrieve instances using 'instanceinfoBeanList = papiWebServicePort.processesGetInstancesByFilter(processidBean, filterBean);', it is always giving me 0 instances.
Have verified in engine db and workspace, there are instances available.
Am I missing to set any params or configuration.
Thanks,
