Using JRUN 4 as application server and struts 1.1-b3.

Project works fine under eclipse 2.1 (MyEclipse 2.6.2). Will not work properly under 3.1.1.

I have tried about eight times to import this project different ways. I have imported as-is with minimal changes all the way to creating a new project under 3.1.1 and simply importing classes and JSP’s. They all seem not to properly define the struts run-time. When creating an new project under 3.1.1 and importing classes, it does seem to define the “action” OK but cannot find the message resources.

In both cases, it does not seem to initialize the validation defined in “validation.xml”, so I know some configuration is not set up properly.

Any considerations I missed when converting projects?

[Gary Gaggiani]

OK. Making progress. Spent a day searching the wrong error messages from above. Searched on java.lang.reflect.InvocationTargetException and got the clue that it had to do with the JDK’s. I changed everything to use 1.4.1_02 and it seems to get past the error. However, is there a way to use JDK 5 in my project? JRUN uses 1.4.1_02, so does that mean that I have to use the same JDK in Eclipse and my project?

[Greg]

I believe that you can’t use java5 if your appserver only understands java1.4. It will throw exceptions like (Unsupported major.minor version 49.0) which I see in your error ouput. Are you using any java5 features? You can make eclipse compile java1.4 code only but you will need to start your JRun with 1.4.X jvm if that is all it supports. You can make MyEclipse start your JRun with a different JDK that you are using for eclipse if you prefer.

[Gary Gaggiani]

It’s more clear now. It should have been obvious. JRUN is running it, so I have to give the appserver what it needs. I am not using any features from JAVA5 yet, but like to stay up with things. I will have to look into JRUN as far as supporting JAVA5. I know how to make Eclipse use JDK 1.4. This can be closed.
