Do you have a working version of this code for SOA Suite 11g PS3. This is our requirement and it would be wonderful to have it.

Some general questions….

1. What experience is there that the Worklist manger is an effective application. Would you recommend this solution.

2. The APEX integration.. has this been very successful.

3. We are a large user of APEX. Can the worklist manger call an APEX form and have the task actions wrapped around the APEX form(s).

I have updated /etc/hosts as
soaserver_ip domain domain.telman.com
and the javax.naming.NameNotFoundException: TaskQueryService not found problem has been solved.
Actually you pointed to it at the begining of this article. but ı have missed it.
Thanks for this excellent article.
Regards,
Telman

Amit, thanks for taking the time to share this! At the time when I wrote this, and with the versions of the software I used for this article, it ran successfully, but if people trying this now with the current versions run into similar issues, this will be a great help! Perhaps you could provide some indication of these issues you mentioned (error messages perhaps?), to help people find your solution through Google!

Thanks again,
Peter

Thanks for this excellent article. It jumpstarted me to use java to access the worklist.

I ran into issues when trying to run. Finally I made sure that I had the following jars in the libraries (and nothing else…so I had to remove BPM Workflow, Oracle 9 iAS etc, as mentioned in this post)
$SOA_HOME/bpel/lib/bpm-infra.jar
$SOA_HOME/bpel/lib/orabpel-common.jar
$SOA_HOME/bpel/lib/orabpel-thirdparty.jar
$SOA_HOME/bpel/lib/orabpel.jar
$SOA_HOME/j2ee/home/jazncore.jar
$SOA_HOME/j2ee/home/oc4jclient.jar
$SOA_HOME/lib/xml.jar
$SOA_HOME/lib/xmlparserv2.jar
$SOA_HOME/webservices/lib/orasaaj.jar
$SOA_HOME/webservices/lib/soap.jar
$SOA_HOME/bpel/system/services/lib/bpm-services.jar
$SOA_HOME/bpel/system/services/config
$SOA_HOME/bpel/system/services/schema
wsclient_extended.jar (download from http://download.oracle.com/otn/java/oc4j/1013/wsclient_extended.zip)

I got this list from http://download-west.oracle.com/docs/cd/B31017_01/integrate.1013/b28981/worklist.htm#sthref2664

The following forum post was useful too

Hi Peter,

One thing I want to Know about this WorkList ,I.e., Can we Assign Some Value for groupTaskId I mean Can we Use the groupTask for Verifications like assigning some constant to it.Because we are getting an at oracle.oc4j.rmi.OracleRemoteException when we assign some value to it.

Thanks
Uday
