Anyone any idea why this error is appearing. I'm filling in details on users and then clickin submit and this is appearing.


java.lang.NullPointerException
app.UserAction.perform(UserAction.java:15)
org.apache.struts.action.ActionServlet.processActionPerform(ActionServlet.java:1787)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1586)
org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:510)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)


Any help would be very welcome

Nicola,
You need to look at the UserAction class. Since it is throwing the Exception in your class, you can debug it. Try looking at that exact line. If you can't figure it out, post the method in which the code is crashing.
