The Type Class is not generic; it cannot be parameterized with arguments <T>

[new_2_java]

Hi all,

I have set up a project in Eclipse 3.1 and am using java 5.0 compiler.

Here's my folder structure in Eclipse

DFS\RemoteClient\TestClient.java

DFS is the project in Eclipse

and this is how it looks my java class

package RemoteClient;

import java.util.*;
// other imports
public class TestClient {
    public static void main(String [] args) throws ServiceInvocationException {
        // business logic here ....
    }
}

So, basically, my java class is just a simple class with a main function.

Now when I build my project, using Project->Clean...

Then I get this as an error at the very first line where i specify the package

package RemoteClient;

This is the error:

The type Class is not generic; it cannot be parameterized with arguments <T>

Can someone please comment on this, as what's this error and why am I getting this.

Thanks.

We will need more than this. Perhaps your code.

Infact there's nothing wrong with the code. I can compile/run this program from OS command prompt. But I wanted to set up a project in Eclipse. and this is where I am getting this error.

the problem is with your class, it won't compile.
If you say it will compile with the Sun compiler and not the Eclipse compiler that problem is either caused by an error in the Sun compiler (extremely unlikely), an error in the Eclipse compiler (more likely), or an error in the way you've configured Eclipse (most likely of all).

Just providing us with random bits and pieces of other code isn't going to do any good in either case.

Not sure what you mean by this.

>> an error in the way you've configured Eclipse (most likely of all).

That's what I am thinking. and because of that, I provided the structure of my project in eclipse in my original post. Maybe I am not using the package and folder structure properly...

[javaAddict]

Just create a new project in eclipse, create the package, and then put the file inside that folder.
Then select your project, right click on it, select properties, Java build path, select the Source tab. There Remove the source folder on build path, and then press Add Folder. Then you choose the folder where your packages will be (the classpath).
You might want to set the Default Output Folder. It will determine where your classes will be created

Thanks Addict,

I will try that, and will update this thread accordingly.

Thanks.
