Hi, We recently migrated from axis 1.4 to axis2 1.6.0. In Production environment we are getting lot of issues. Some of the exceptions are listed below. We are trying out different options with the retry mechanism of the HttpMethodDirector. The environment is JBOSS 4_2_1 and JDK 1.6. If any of you have information or suggestions please mail me. Appreciate your help.
Thanks and regards, Natanasabai. Exception 1: ============ Stack Trace:java.lang.reflect.InvocationTargetException .............. ..............
