Using the WS API, I need to obtain a list of all processes available to the authenticated user. I was told the following code snippet should do what I need:
ProcessSearchOptions options = new ProcessSearchOptions();
options.setWhere("");
ProcessResult result = workflowService.getListProcessesResults(workflowService.listProcesses(options));
for (ProcessInstance instance : result.getProcesses())
{
// do the stuff
}
But this yields the following exception:
Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: java.lang.NullPointerException
