I saw something similar on Friday, but haven't debugged it yet. I tried a quick switch from Weblogic to Tomcat, and the null pointer exception I was getting was caused by my Action receiving a null Form Bean. I believe that if you link to myPage.do , the Struts framework will create an empty Form Bean for you, and hand it to your Action, for me, this was not occuring. My form was null... I don't think this should ever happen.
I suspect there is something wrong with my configuration, but as I said I haven't debugged it yet. -Don -----Original Message----- From: James Mitchell [mailto:[EMAIL PROTECTED]] Sent: Saturday, December 21, 2002 3:30 PM To: 'Struts Users Mailing List' Subject: RE: Struts beta 2 and Tomcat 4.1.18 You'll have to provide more information for anyone here to help you. -- James Mitchell Software Engineer/Struts Evangelist http://www.open-tools.org "C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg." - Bjarne Stroustrup > -----Original Message----- > From: ajTreece [mailto:[EMAIL PROTECTED]] > Sent: Saturday, December 21, 2002 1:49 PM > To: Struts Users Mailing List > Subject: Re: Struts beta 2 and Tomcat 4.1.18 > > > I saw that, but was wondering if it was something more specific to a > Tomcat configuration with Struts...
