I am working on a plugin, which needs to check current classpath entried
of dynamic web project. I can get a reference of IProject and I want to
get IJavaProject so that I can retrieve all IClassPathEntry. I have tried

IJavaProject javaProject = project.getAdapter(IJavaPorject.class);

But it returns null.

Did i do it wrong? How can I get reference of IJavaProject from IProject?

Thanks

William

That's how you'd do it. It's probably returning null because it doesn't know how to adapt to that type. You might find that there's some specialised subclass for DynamicWeb projects (IDynamicWebProject, for example) that it knows how to adapt to and as an added bonus, IDynamicWebProject may be a subtype of IJavaProject.

It sounds like it might be a desirable feature, and it would only be an extra few lines of code, so you might want to submit an enhancement request for this in the future.

I've had a quick look at the JavaDoc for the WTP and can't see anything that would suggest there is an IDynamicWebProject, but if you've got it imported into your workspace I'd suggest trying to look for implementors of IProject to see what comes up.

I've used:

(IJavaProject)iproject.getNature(JavaCore.NATURE_ID);

Cheers,

I think the normal way is:

IProject project = getProject();
IJavaProject javaProject = JavaCore.create(project);
if (javaProject == null || !javaProject.exists()) {
// current project is not a Java project
}
