invoke a SSB's method from another SSB in another PC
I have a stateless session bean(SSB) TransactionSBean deployed in PC A, and a SSBTransactionS2 deployed in another PC B (which have IP address 192.168.1.12).
I want to invoke the method getTerminalList() of TransactionS2 from TransactionSBean. My code is:
//in TransactionS2Bean.java
//TerminalCMP is a CMP entity bean
//Terminal is a class that implements Serializable interface
public java.util.Collection getTerminalList()
{
try
{
TerminalCMPHome home = (TerminalCMPHome)jndiContext.lookup("TerminalCMPBean");
Collection r_C = home.findAll();
Collection ret = new ArrayList();
Iterator iter = r_C.iterator();
while (iter.hasNext())
{
TerminalCMP terCMP = (TerminalCMP)iter.next();
Terminal ter = new Terminal();
ter.setTerminal_id(terCMP.getTerminal_id());
ter.setTerminal_name(terCMP.getTerminal_name());
ret.add(ter);
}
return ret;
}
catch (Exception ex)
{
return null;
}
}
//in TransactionSBean.java
public java.util.Collection getTerminalList()
{
try
{
Properties p = new Properties();
p.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
p.setProperty("java.naming.provider.url", "jnp://10.206.16.18:1099");
p.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
Context ctx = new InitialContext(p);
Object objref = ctx.lookup("TransactionS2");
TransactionS2Home myhome = (TransactionS2Home)PortableRemoteObject.narrow(objref, TransactionS2Home.class);
System.out.println("Lookup completed");
return myhome.create().getTerminalList();
}
catch (Exception ex)
{
System.out.println("Remote error: getting TerminalList. Starting print stacktrace");
ex.printStackTrace();
System.out.println("End stacktrace");
return null;
}
}
when I invoke method getTerminalList() of TransactionSBean in PC A, my jboss screen shown:
15:11:00,468 INFO [STDOUT] Lookup completed
