just trying to get to grips with JBOSS AS4.2 and new to the environment.
Really trying to get to EJB3 but doing it bit by bit and want to be able to
call session bean services from a test application client - that i can run in
eclipse.
deployed 4.2 and configured a My sql XA datasource as follows.
|
| <datasources>
| <xa-datasource>
| <jndi-name>jdbc/willsDS</jndi-name>
| <use-java-context>false</use-java-context>
|
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
| <xa-datasource-property
| name="URL">
| jdbc:mysql://localhost:3306/test
| </xa-datasource-property>
| <user-name>will</user-name>
| <password>will</password>
|
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
| <max-pool-size>5</max-pool-size>
| <min-pool-size>1</min-pool-size>
|
| <blocking-timeout-millis>2000</blocking-timeout-millis>
| <idle-timeout-minutes>2</idle-timeout-minutes>
| <track-connection-by-tx>true</track-connection-by-tx>
| <no-tx-separate-pools>false</no-tx-separate-pools>
|
| <exception-sorter-class-name>
| org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter
| </exception-sorter-class-name>
| <metadata>
| <type-mapping>mySQL</type-mapping>
| </metadata>
|
| </xa-datasource>
| </datasources>
|
This all goes well - and when i start the server inside eclipse i can see the
datasource in the JNDIView tree
i've registered the datasource in the global tree and not the java: default
part as the JNDI FAQ says you cant see the java: tree unless its in the same VM.
i've checked netstat - a and port 1099 is being listened on when i run the
server up.
next created a simple client app (as an EJB project in eclipse to pickup the AS
libraries if nothing else)
my simple app client looks like this - at the mo i'm just trying to get a
simple JNDI lookup to the datasource in the AS (no DI here as its an standalone
client)
|
| package org;
|
| import java.sql.Connection;
| import java.util.Hashtable;
|
| import javax.naming.InitialContext;
| import javax.sql.DataSource;
|
|
| /**
| * @author Will
| *
| */
| public class Test
| {
|
|
| public static void main(String[] args) throws Exception
| {
|
|
| InitialContext ctx = getInitialContext();
| DataSource ds;
| Connection conn;
|
| //llookup ds via jndi in global tree - using
jnp://localhost:1099 - see helper function above
| ds = (DataSource) ctx.lookup("jdbc/willDS");
| conn = ds.getConnection();
| conn.close();
|
|
| }
|
| public static InitialContext getInitialContext() throws Exception
| {
| Hashtable props = getInitialContextProperties();
| return new InitialContext(props);
| }
|
| private static Hashtable getInitialContextProperties()
| {
|
| Hashtable props = new Hashtable();
| props.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
|
props.put("javax.naming.Context.PROVIDER_URL","jnp://localhost:1099");
| props.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces" );
| return props;
| }
| }
|
when i run the app however i get varying errors depending on whether i set the
provider_url or not.
code shows me setting the provider_url and get error

on an earlier go i got errors about cant find bound class jdbc - but i cant get
that at present - and now stuck on the above.
I'll never progress to anything smarter if i cant sort the basics out - what am
i doing wrong, any ideas please?
