newbie on workspace resource programming [message #213164]

Hi everyone,

I posted a similar question some times ago, but unfortunately I didn't get
any really helpful replies and still get stuck with the problem.
It is about workspace resource programming. I'd like to create a plug-in
which in turns generate another plug-in project.
Luckily I have the Java Dev. Guide to Eclipse book which gives some hints on
creating a project programmaticaly. But then I still can't find any way to
create packages within the project. In the book, there are some codes, which
more or less look like this:

IFolder myFolder = myProject.getFolder("myPackage");
myFolder.create(true,true,null);
IJavaElement myPackageFragment = JavaCore.create(myFolder);

But this only gives me a folder, and not a package.

Can anyone please give me some hints on how I can create packages using the
workspace API? And also, on how to define the src/bin separation on the
project?

Thanks in advance!

Regards
Paul

Hi Ed,

thanks for the code and sorry for the late reply.
I already had a look at the code when you told me last time about this =
method. But somehow I overlook some important parts so I couldn't get =
the result I wanted.
But after I get the very same answer from you, I gave it a try once more =
and now it works.
Thanks again and sorry for the double post. Hope you don't get bored =
with this kind of newbie question.

Have a nice weekend!

Regards
Paul

Hi everyone,

I posted a similar question some times ago, but unfortunately I didn't =
get
any really helpful replies and still get stuck with the problem.
It is about workspace resource programming. I'd like to create a plug-in
which in turns generate another plug-in project.
Luckily I have the Java Dev. Guide to Eclipse book which gives some =
hints on
creating a project programmaticaly. But then I still can't find any way =
to
create packages within the project. In the book, there are some codes, =
which
more or less look like this:

IFolder myFolder =3D myProject.getFolder("myPackage");
myFolder.create(true,true,null);
IJavaElement myPackageFragment =3D JavaCore.create(myFolder);

But this only gives me a folder, and not a package.

Can anyone please give me some hints on how I can create packages using =
the
workspace API? And also, on how to define the src/bin separation on the
project?

Thanks in advance!

Regards
Paul
