Eclipse WTP Tomcat startup problem/Spring bean problem

Hi,
i'm having the following problem:

I've been developing a program with Eclipse Galileo WTP using Struts/Spring2.5/Hibernate3.0.
When i run the program using a Server (in Eclipse WTP) i can access it using http://localhost:8080/NameProgram and everything works fine.

Now i wanted it to deploy to Tomcat 5.5.15. So i created a .WAR file (using Export -> War file ->...) and dropped it under the webapps folder under the Tomcat installation.
When i started Tomcat, the .WAR file was extracted but got the following error at startup:

After searching the web i found that this class should be available in rt.jar which is in my Eclipse project (Properties → Java Build Path → Libraries → JRE System Library) but not in the in .WAR file that i created, shouldn't Tomcat find this jar's autmatically?

The class was also availbale in activation.jar, so in copied this jar in my WEB-INF/lib folder and made a new .WAR, now Tomcat startup was OK.
I can acces the program, but when i trie to access Spring Beans i get the following error, it seems that my beans are not being initialized:

You did need activation.jar in your war. That's not a problem.

Your second problem looks like probably a NullPointerException in the SpringServiceLocator class, and most likely that the factory object wasn't initialized.

Thanks for your help, but after looking carefully at the problem i saw that my beans are getting called fine.
The problem has something to do with de database connection i think.
I'm using MySQL, the database is up and running and I have the mysql driver mysql-connector-java-5.1.12-bin.jar in WEB-INF/lib.
At startup everyting of hibernate seems to map to my *.hbm.xml files, so this should be fine.
Anyone any idea?

I FINALLY worked it out. I'm using springs DI(depency injection) or IOC (inversion of control) with annotations.
In Eclipse WTP the @Resource (javax.annotation.Resource) exists in rt.jar which is default in the project. When i created the WAR the rt.jar is not in the WAR. So i had to put the jsr-250-api.jar in WEB-INF/lib.
Same problem for stringvalue.isEmpty(). Replaced that with StringUtils.isEmpty(String).

Is there an easy way to dectect that you're using rt.jar when you shouldn't?
Why does Eclipse WTP Galileo works this way? I find it very confusing!!!
 
I agree. Here's the link: http://aspose.com/file-tools
