Eclipse: No Java under Run Menu

JerryMcFarts · 03-31-2006, 01:02 AM

Hello,
I am trying to learn a few suites of Programming on the Linux side. My question is currentl on the Java Programming Language. I have installed eclipse and it runs nice and smooth.

But when i was doing the tutorial, doing the "Hello World" program. I went to "Run -> Run As ->" but there is no "Java" option

It only shows "eclipse Application". I konw Java is installed:

Code:

$ java -version
java version "1.4.2-02"
Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.4.2-02)
Java HotSpot(TM) Client VM (build Blackdown-1.4.2-02, mixed mode)

Can we take a look at the code? If you don't have a public static void main method you won't be able to run as application. I also am wondering if you have Java SDK, not only the RE.

The Code is pretty huey. I have never really done any Java here is there Eclipse code, from the welcome tutorial, that I put in

Code:

public class HelloWorld {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
System.out.println("Hello World!");
	}
}

But the real problem is there no Java option under the Run pulldown.

How would I check if I had SDK on my system?

usually the first time you attempt to run an application you have to right click on the source file in the file navigation panel and goto run, then you should see run as java application..

it does not seem to showup initially on the top menu for some reason..

to see if you have sdk try a `locate javac` and see what it says..

Code:

$ locate javac
/usr/share/doc/ant/manual/OptionalTasks/javacc.html
/usr/share/doc/ant/manual/CoreTasks/javac.html
/usr/share/vim/vim63/syntax/javacc.vim
/usr/share/vim/vim63/compiler/javac.vim

I don't know if that means my SDK is installed.

So I did that an I believe it ran. Displayed Hello World in bottom of the screen. Sweet.

cool! its alive! muwhahahaha!

anyhow.. no the results you got back from locate are not saying you have sdk installed..

but apparently it is either on there somewhere else or eclipse is compiling it.. i have not looked behind the scenes in eclipse to see what it will do if there is no sdk, maybe it has its own version.. ??

anyhow since your program executed then there has to be somthing there.. not that you have run it once is is runnable by clicking the run button at the top of the screen? it should be..

yes now it's up top. in the Run Menu. Eclipse is pretty neat. I have used Visual Basic .Net and It is nice to build Windows and applying Widgets.

Does Eclipse offer this feature? From what I see I don't see anything of that nature. I also was looking at Glade, which does that, but I having separate problems with that program :-P

yeh eclipse is nice.. i use it pretty much all day every day and have few complaints.. there are a couple of weird things it will do sometimes.. but still its the best java ide i have used..

and there is a plugin for eclipse call VE or 'visual editor'.. you can find it on the eclipse website.. it will assist in building uis..

I believe NetBeans has Matisse for such a feature.

There's even an eclipse plugin in the works:

Eclipse compiles using the Eclipse Compiler for Java (ecj) so all it needs is a JVM.
