Exception while calling DOC_INFO service from a filter

Question

Hello All,
I am coding for a requirement where I need to extract the document meta-data information (author) and sent out the mail notifications to the original doc-author whenever a workflow on a document is finished.
For this I hooked a custom java code as a filter to the event *"advancedocumentStartMarkWorkflowFinished"*. I referred to the thread below to do my coding. I am thinking to execute DOC_INFO service from my filter and extract the required values.
http://forums.oracle.com/forums/thread.jspa?messageID=9501388�
My execute service method is given below:
public void executeService(DataBinder binder, String userName,
boolean suppressServiceError, Workspace workspace) throws DataException,
ServiceException {                                                                                     
// Workspace workspace = getSystemWorkspace();
String cmd = binder.getLocal("IdcService");
System.out.println("The service to be called is-->"+cmd);
if (cmd == null) {
System.out.println("Getting the service failed");
// throw new DataException("!csIdcServiceMissing");
System.out.println("Workspace in execute-->"+workspace);
ServiceData serviceData = ServiceManager.getFullService(cmd);
if (serviceData == null){
//throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined",
//null, cmd));
System.out.println("**** Null is serivice data ****");
System.out.println("Creating the service");
System.out.println( "%%%%%%%%%%%%%%% Class id"+serviceData.m_classID);
Service service =
ServiceManager.createService(serviceData.m_classID, workspace,
null, binder, serviceData);
System.out.println("Retrive user details---------->"+userName);
UserData fullUserData = getFullUserData(userName, service, workspace);
service.setUserData(fullUserData);
binder.m_environment.put("REMOTE_USER", userName);
ServiceException error = null;
try {
System.out.println("********Setting flags/checks now now..");
System.out.println("************* Step 11");
service.setSendFlags(true, true);
System.out.println("************* Step 2");
service.initDelegatedObjects();
System.out.println("************* Step 3");
service.globalSecurityCheck();
System.out.println("************* Step 4");
service.preActions();
System.out.println("************* Step 5");
service.doActions();
System.out.println("************* Step 6");
service.postActions();
System.out.println("************* Step 7");
service.updateSubjectInformation(true);
service.updateTopicInformation(binder);
System.out.println("********Setting flags done succesfully....");
} catch (ServiceException e) {
System.out.println("??????????????????????? Caught an error");
error = e;
Now , I find that after step 5 (above) the code throws an exception. The exception trace is given below. Any help is highly appreciated. I am not able to find much help. I referred to the Stellant Developer Guide it also contains the example similar to the code given in the thread above. Is it version related issue where the code not valid for 11G or I am doing something wrong?
I found even though the service called threw an exception I was still able to retrieve the docname and author values which I need. Moreover, the workflow was also finished. I am confused because of this.
Name of doc apex.log AUthorweblogic (See lines in bold in the stack trace)
Please help I am quite stuck at it. Any help is highly appreciated .
Thanks,

Answer 1

It looks like the main error that is being thrown is "csJdbcCommitCalledInAutoCommitMode". Somewhere when executing the DOC_INFO service, the database transaction is being released (at intradoc.jdbc.JdbcWorkspace.releaseConnection(JdbcWorkspace.java:2383)).
Is there a reason why you are hooking into the advancedocumentStartMarkWorkflowFinished filter? I have generally found better success hooking into the serviceCleanUp filter if I need to commit a database transaction. serviceCleanUp is fired at the end of every single service call but should be far enough out of the service call so no database transactions are pending. If you use the serviceCleanUp filter, you will need to check for some criteria so that your customized code only runs in the specific scenario needed. Try to make this customized code as concise and quick as possible since this service gets called a lot.
