Andre. javax.servlet.ServletException: Missing message for key welcome.title Thats the reason. You have to put your message keys into a directory that is containing to the classpath.

Re: concurrency in struts
There are two concepts you have to understand: thread-safe and reentrant. A method is reentrant, if many threads can enter the method as the same time without conflicting. For that you only have to act on parameters and local variables. Threads only share the data- and the code-segment of an application. Every thread gets his own stack-segment, where all local variables and the parameters will be push onto. If you act in the execute-method only on the parameters and on local variables you are thread safe. If you will join shared ressources as database connections ... you have to take care, that such ressources are either pooled or the access is sychronized. So the message is: In the execute Method don't use global variables but only local variables. This and the parameters are pushed on your stack, that is only in your thread visible. Hope it helps Manfred Wolff Jignesh Patel wrote: Riyad, But does this methods are synchronized? Otherwise if two threads execute at the same time they can access the method at the same time. And result will be big mess. -Jignesh On Monday 10 May 2004 18:29, Riyad Kalla wrote: This question is actually what made me sign up to this mailing list... the answer is that there is no implicit concurrency. All your work/variables in Actions should be method-scoped and not use ANY class variables because of this. My specific questions was that I wanted to use a class variable ActionErrors so any of my methods (DispatchAction) could add errors without initializing a new ActionError instance, and return it. But this is incorrect and can/will introduce problems. So there is no concurrency in Struts.

Don't forget the message resource bundle, where the keys button.consult
and button.search are defined!

Mu. don't define that.do but only /that and evrything will work fine. Be care, that you have described a servlet extension mapping in your web.xml.
