java.lang.ClassCastException, jboss-4.0.3SP1, JMX service, webservice

[popianovka]

[u][b]Problem :[/b][/u]
I'm try to use the lookup("Quartz") Scheduler object, but can't cast it. I'm getting
a ClassCastException. I'm doing this in a webservice methode..
(using netbeans 9 beta). Datasource and JMX Quartz service seem to be installed in Jboss....

If You look at the test code I have written, It seems that the reference to a Schedule object exists !

What s wrong ?

Thanks !
[i](I have tried usinging the Quarts servlet, but how should I get the servlet context from a webservice methode (axis) ?)[/i]

[u][b]Code:[/b][/u]
InitialContext iniCtx = new InitialContext();
Object a = iniCtx.lookup(jndiName);
String aa= a.getClass().toString();
String aaa=a.toString();
System.out.println(aa);  --->SHOWS "class org.quartz.impl.StdScheduler"
System.out.println(aaa); -->SHOWS "org.quartz.impl.StdScheduler@1891842"

 try{org.quartz.Scheduler s=(org.quartz.Scheduler)a;} catch(Exception ee) {System.out.println(ee);}
->SHOWS  
":java.lang.ClassCastException:org.quartz.impl.StdScheduler"          

try{org.quartz.impl.StdScheduler ss=(org.quartz.impl.StdScheduler)a;} catch(Exception eee){System.out.println(eee);}
-->SHOWS
java.lang.ClassCastException: org.quartz.impl.StdScheduler

This is probably a classloading issue.  Make sure the quartz jars are in one place, and that they aren't being loaded twice, once by your web app and once by your j2ee app.  (You can look at the two StdScheduler classloaders to verify my theory)

Thanks !

It solved the problem !

I let the Jboss keep the the jar files (Server/lib) because of the JMX Quarts managed bean.¨

I deployed the war file without the Quartz files (webservice services), and now it works !
