I am exposing an API in my Session Bean as Web Service in Weblogic6.1sp2 as: public ArrayList getUserList(); Question is: 1. As Weblogic does not support ArrayList object type, how can I capture the object back in one of my web service client? 2. How also can I capture the String return value of the result from my client? 3. Is there any XML file which I need to change to enable this object type to be passed from my Java application and to be understood by the other application? Thanks a lot.
