[jboss-user] [Beginners Corner] - Running tasks at application deployment

[draken]

Hello everybody,

I need to perform a simple task (i.e. fetch data from my DB) during (or exactly 
afterwards) my application's deployment on JBoss. Is there any way to achieve 
this?

thanks in advance for your answers and sorry if this question was asked before,

Draken

[jboss-user] [JBossWS] - LinkageError when connecting to webservice

[draken]

Hi,

I'm trying to connect (using Apache Cactus ServletTestRunner) to a WS deployed 
on JBoss4.0.5GA, and I'm getting the following exception:

  | loader constraints violated when linking 
org/jboss/util/xml/JBossEntityResolver class

The code I'm invoking is:

  | 
  | try {  
  |   URL url = new URL(WSDL_URL);
  | 
  |   QName qname = new QName(WS_NAMESPACE, WS_NAME);
  | 
  |   ServiceFactory factory = ServiceFactory.newInstance();
  |   Service service = factory.createService(url, qname);
  | 
  |   ()
  | } catch(Exception e) {
  |   e.printStackTrace();
  | }
