Listing the Human tasks through Workflow API

Question

The workflow API uses oc4jadmin as the user to get the workflow context. what if we dont have the credentials of oc4jadmin but of a normal user to whom a task is assigned. I am not able get the workflow context by using the credentials of a simple user.
I am using :
workflowContext = getTaskQueryService().authenticate(WF_MANANAGER_UN, WF_MANANAGER_PW, LDAP_DOMAIN, worklistUser);
List tasks = getTaskQueryService().queryTasks(getWorkflowContext(), displayColumns, optionalInfo, "My+Group", null, whereclause, null, 0, 0);
when i change the user name and password from oc4jadmin, it throws an exception of "null pointer"

Hi,
We solved this issue by applying the following steps:
* Create a shared library on the OC4J container using the same name (oracle.ifs.client), but another version (10.1.2). Actually, give it the version of your Content Services version.
* Upload the following JAR files to the shared library from the previous step: axis.jar, commons-discovery-0.2.jar, commons-logging-1.0.3.jar, content-ws-client.jar, http_client.jar, log4j-1.2.14.jar, wsdl4j-1.5.1.jar. Important: use the JAR files from you Content Services installation, not the JAR files from the Oracle AS installation (that containes another version of those JAR files).
* When you deploy the client application that accesses Content Services make sure you import the oracle.ifs.client shared library, but include a max-version attribute that equals your own shared library. That way, the correct JAR files are loaded instead of the newer version.
