Hi,
I have created webservice which uses JAAS to validate the user and than fetch data from the oracle database using CMP(EJB) beans. The application server is weblogic 7.0.
Above application works fine with 3 user concurrently hitting the webservice by using the Load Runner testing tool. If the number of users exceed 5 than the following error occurs on weblogic application server console.
