Hi all,
can someone tell me, whether this information is correct?
Client part:
- To deploy my client program that access the
jboss server I need these jboss' dependent libs
(from client directory)?
* deploy.jar
* jboss-client.jar
* jnp-client.jar
Can someone explain to me, what are these jars actually
doing? What is jnp?
Okay, you also need other jars like ejb, jndi, rmi,
jndi-prop file and so on but this also applies
for other EJB server.
Server part:
- ejb-jar.xml is the dd for all ejbs. This is
jboss independent.
- jboss.xml is typical jboss? one also puts the
jndi's names in this file for every beans.
Database conn:
I have 2 choices to use a database connection:
1. First I put my database connection, e.g. "Interbase"
in jboss.conf file and after this
I can access it through DataSourceImpl,
because jboss.conf properties map to the parametres of
org.jboss.jdbc.DataSourceImpl. Is this correct?
For example: I can get the connection like this:
InitialContext ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup("Interbase");
con = ds.getConnection();
But this is only interesting, if I want to write
BMP or session beans, right?
I can't use this technique to write CMP beans.
2. To write CMP beans I think I need JAWS jaws.xml, is
this correct? But I can't figure out, how I can
access more than one DB at one time? Because jaws.xml
only gives you one datasource, like this:
<datasource>Hypersonic</datasource>
<type-mapping>Hypersonic SQL</type-mapping>
Thank's a lot for your helps!
BTW.: Rickard, I cannot compile your client program because
this file is missing: MBeanRegistration. This file is used
by the main.java file
...
public class Main
implements MainMBean, MBeanRegistration
...
But it's okay, I just wrote my own simple client program and
it works!
Thank's!
