Hi there, folks. Sorry if this is a dumb question, but I couldn't find any good explanation so far.
I have the following code, a plain and simple *HelloWorld*:
ClassPool pool = ClassPool.getDefault();
CtClass cc = pool.makeClass("HelloWorld");
CtMethod mt = CtNewMethod.make("public static void main(String[] args) { System.out.println(\"Hello World!\"); }", cc);
cc.addMethod(mt);
cc.writeFile();
As you see, there's a main method in this new generated class. So far, so good. It works like a charm.
I'd like to create this very same method using the other way:
CtClass cc = pool.makeClass("HelloWorld");
CtMethod m = new CtMethod(CtClass.voidType, "main", new CtClass[] { } , cc);
m.setModifiers(Modifier.PUBLIC & Modifier.STATIC);
cc.addMethod(m);
m.setBody("{ System.out.println(\"Hello World!\"); }");
cc.setModifiers(cc.getModifiers() & ~Modifier.ABSTRACT);
cc.writeFile();
Unfortunately, this code fails. I couldn't figure out how I'm supposed to handle String args[] with CtClass.TYPE, as it seems there are only primitive types.
Thanks a lot!

[Beginner's Corner] - Problem starting jboss-5.1.0.GA from Eclipse

--------------------------------------------------------------
Just installed jboss-5.1.0.GA on XP Pro, it starts in command line but errs in Eclipse.
*Environment:*
JVM:1.6.0_20
Eclipse using: 1.6.0_20 (windows-preferences-java-installed JREs)
CLASSPATH=.;c:\dev\jboss\jboss-5.1.0.GA\bin\run.jar;C:\Program Files\Java\jre6\lib\javaws.jar;C:\Program Files\Java\jre6\lib\ext\QTJava.zip
I was successful in start/stop from command line using net start/stop JBAS50SVC
*A side question:*
once started from cmd line, localhost:8080 says: The requested resource (/dev_home.html) is not available
I was expecting welcome/something else for a freshly installed jboss root.
I am novice.
Thanks in advance!

The error you are seeing means it is not liking the space in the path, and it is interpreting tha the path is only C:\Documents:
-javaagent:C:\Documents and Settings\PC\Bureau\JBossAOP\eclipse\jboss-aop-2.1.8.GA\lib\jboss-aop.jar-Djboss.aop.path=C:\Documents and Settings\PC\Mes documents\Downloads\travail\jboss\SINGLETONS\jboss-aop.xml
I would try adding " or ' to see if the problem is solved:
-javaagent:"C:\Documents and Settings\PC\Bureau\JBossAOP\eclipse\jboss-aop-2.1.8.GA\lib\jboss-aop.jar" -Djboss.aop.path="C:\Documents and Settings\PC\Mes documents\Downloads\travail\jboss\SINGLETONS\jboss-aop.xml"
or
-javaagent:'C:\Documents and Settings\PC\Bureau\JBossAOP\eclipse\jboss-aop-2.1.8.GA\lib\jboss-aop.jar' -Djboss.aop.path='C:\Documents and Settings\PC\Mes documents\Downloads\travail\jboss\SINGLETONS\jboss-aop.xml'
It's been ages since I stopped working on Windows, so I'm not sure which one of those would work. Another (lame) alternative is adding your stuff to a path that has no spaces in it.
You also need to add a space char before the -D, as I did above, otherwise it won't work.
