How to reference a bean from another eclipse project

[jakim8915]

I have 2 projects (one struts project and a java project to contain my DAOs and business logic in eclipse). In my Struts project, I've setup my spring context to refer to beans within the same Struts project and it works fine. But when I need to to set some bean references to my java library project, it fails. Here are the error messages:

In eclipse, I have set the struts project to be dependent on the java library project. Im not sure if there's anything else I need to do to create bean references in my struts project that reference the java library project. Im new to Spring and any help/suggestions is appreciated.

FYI. Im using Spring 1.2.3, Eclipse 3.1, MyEclipse 4.0M3, Tomcat 5.0.


Thanks.

It seems that Tomcat you're starting from MyEclipse doesn't see your Java project (where needed classes are). You should check MyEclipse on how to set referenced projects, or something similar. Nothing to do with Spring itself, really.

Thanks dcengija, thats what I thought so I just packaged the java project in a jar and placed it in my WEB-INF\lib folder and it works. I know I have MyEclipse setup properly because I can reference the Java project (ex. I can access the business service objects in my struts action classes.)

Is there a better way of developing a web app with struts & spring in one project and a java project with business logic and DAOs? I mean, I dont want to be exporting my java project as a jar every single time just so I can test my web app. Or maybe Im just taking the wrong approach. Any help is appreciated.
