Re: [JBoss-user] JNDI name for datasource in JBoss2.4.4_Tomcat4.0.1 + MySQL
Thanks a lot. Danch. Now, I am using: ctx.lookup(java:/Customer) and change java:/DefaultDS to java:/Customer, my lookup code works fine. So I assumed if i change java:/Customer back to java:/DefaultDS, I also can lookup for java:/DefaultDS. I will try to use java:comp/env/jdbc/Custmoer and the old setting later. danch wrote: You're close! See comments inline below. -danch Christine wrote: Sorry for miscopy in my previous email!

Re: [JBoss-user] JNDI name for datasource in JBoss2.4.4_Tomcat4.0.1 + MySQL
Why should jdbc/Customer be bound? if your code is in an ejb, you wouldn' link from web.xml or jboss-web.xml but the ejb counterparts. If its in a servlet, looks like you want to look up jdbc/MilosDataSource david jencks On 2002.03.01 18:44:41 -0500 Christine wrote: Hi, Since I didn't get any reply, I am using another approach now.

Re: [JBoss-user] JNDI name for datasource in JBoss2.4.4_Tomcat4.0.1 + MySQL
I am sorry to confuse you by my mistake. I have a database in MySQL called Customer, which is specified in jboss.jcml. mbean code=org.jboss.jdbc.XADataSourceLoader name=DefaultDomain:service=XADataSource,name=MySQLDS attribute name=PoolNameDefaultDS/attribute attribute name=DataSourceClassorg.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl/attribute attribute name=URLjdbc:mysql://localhost/Customer/attribute Now, I wanted to use bind my database Customer to JNDI server with name jdbc/customer and then I can use JDBC connect to my database from my EJB code. So my question is how I should specify deploy descriptors to bind database Customer to JNDI server?
