[esb-java-dev] [jira] Resolved: (ESBJAVA-325) AxisConfiguration is set to null, hence NPE thrown when editing proxy service after updating the synapse configuration

[indika kumara (JIRA)]

     [ http://www.wso2.org/jira/browse/ESBJAVA-325?page=all ]

indika kumara resolved ESBJAVA-325.
-----------------------------------

    Resolution: Fixed

This issue was occurred because  after update the synapse configuration using the configAdmin(ESB Console)...we did not set the axis configuration to the synapse configuration ....So after that if we try to add a proxy service(when adding proxy service it deal with axis configuration...because proxy service is  a axis service.).... then NPE will throw. I fixed the issue.
