  1. POWebSphere ClassNotFoundException when invoking WebService after startup (but not later)
    text
    copied!<p><strong>Update</strong>: The <code>ClassNotFoundException</code> only occurs if I try to use the web service immediately after starting the application. If I wait (for some unknown event/duration) the application will work.
