How to set category and category attributes through BPEL?

Question

Greetings.
I have seen ContentServices SDK, and tried to build own BPEL process which should make this work.
But there is exception when authenticate to OID. If i not place password attribute to ContentServices.login method, there is exception like "Unable to retrieve application credentials from OID".
If I place password, then exception is following: "Cannot uthenticate user using clear text password".
In ContentServices web services SDK is example, called "ApplyDocumentTypeCategory", where in GetUserName assign activity you copy value of "/ns3:IFSQUEUEMESSAGE/PARAMETERLIST/PARAMETERLIST_ITEM[NAME='CONNECTASUSER']/VALUE"
to connectasuser variable. What should contain this variable?
If anybody knows how to solve this, please help.
Thank you.

BPEL process finished without any errors, but there is no results in document category
here is function which call addCategoryAttributeValue. in Java Embedding activity seems it executes, but variable result not updated after executing this function.
public String perform(ContentServicesSession session) throws Exception
String result=new String("BEGIN");
try
result=result.concat("1");
Item[] documents = WorkflowUtils.getTargetDocuments(session,
mWorkflowid);
result=result.concat("2");
int len = (documents == null) ? 0 : documents.length;
for (int i = 0; i < len; i++)
result=result.concat(Boolean.toString(WorkflowUtils.addCategoryAttributeValue(session,
documents,
mCategoryName,
mAttributeName,
mAttributeValue)));
catch (Exception e)
result=result.concat(e.getMessage());
finally {
session.logout();
return result;
and here is piece of code where i call this function(Java Embedding activity):
CategoryTest action = null;
String res="";
try
//get the workflow id.
String workflowid =(String) getVariableData("workflowid");
String filesEndPoint = "http://myhost.com:7778/content";
String user = (String) getVariableData("username");//username=orcladmin#welcome1
java.net.URL u = new java.net.URL(filesEndPoint);
// get the workflow parameters
String categoryname = (String) getVariableData("categoryname");
String attribname = (String) getVariableData("attribname");
String attribvalue = (String) getVariableData("attribvalue");
//String documenttype = (String) getVariableData("documenttype");
// get the PartnerLink.
com.collaxa.cube.engine.types.bpel.CXPartnerLink
plink = (com.collaxa.cube.engine.types.bpel.CXPartnerLink)
getVariableData("GetDataFromCS");
res +="|connected";
// Create a Content Services Session.
ContentServicesSession session =
ContentServicesSession.login(plink,filesEndPoint,user,"");
res +="|logged in";
// Run the java helper class.
action = new CategoryTest(workflowid);
action.ApplyCategoryValue(categoryname, attribname, attribvalue);
res+="|applied attributes";
// Perform the workflow operatio using the given session.
res += action.perform(session);
res+="|action performed";
setVariableData("exception", res);
catch(Throwable ex)
setVariableData("exception", ex.getMessage());
after executing this code, variable "exception" has following value: |connected|logged in|applied attributes|action performed
I don't know what to do, plase advice me.
Thanks,
