Re: Dumb Question -- JAVA400-L

Jon,

I am not an iSeries java guru, but I am learning Java using Eclipse. What this error means to me is that it can't find the class TestClass because it is not in your current directory. In my environment, the classes are generally one directory level lower in my "classes" directory. In that case, you could call your java program by specifying the class path:

java -cp ./classes TestClass

In my case, this takes me one directory down from my project directory to the directory (classes) where the java .class objects get created. Note that you must specify the "." (indicating the current directory) in front of the/classes.

My directories would look something like this:

ProjectA
->src
->classes

When I compile my java source, the classes get created in the classes directory. Then when I run from the command line, I usually run from the ProjectA directory, which is why I need the -cp ./classes.

Another way to specify where the classes are (in the Eclipse world in Windows) is to specify the directory that has the classes in the system environment variable for CLASSPATH. Perhaps there is something like this for the iSeries, but I don't know where it is.

Hope this helps, even thought it is not directly related to iSeries

I am having trouble getting _any_ Java code to run on my iSeries

I have reduced the java to a tiny class i.e.

public class TestClass
{
        public TestClass()
        {
        }

        public static void main(String args[])
        {
                System.out.println("Welcome to class TestClass");
        }
}

This compiles just fine but produces:

java TestClass
java.lang.NoClassDefFoundError: TestClass
      java/lang/Throwable.<init>(Ljava/lang/String;)V+4 (Throwable.java:85)
      java/lang/Error.<init>(Ljava/lang/String;)V+1 (Error.java:41)
      java/lang/NoClassDefFoundError.<init>(Ljava/lang/String;)V+1
(NoClassDefFoundError.java:38)

When I try and run it.

I haven't a clue what is wrong and therefore no idea where to look - can
anyone suggest anything
