Hi,
We would like to test our J2EE app. on a JBoss-Tomcat platform. We have
a mixture of servlets and EJB's and I have used the deployment tool to
generate a jboss.xml file. When this is packaged in our ear file the
deployment seems to go ok and I can see the file being exploded and the
web context being created.
My problem is that I can't seem to access a database connection pool
from within the first servlet. We are using an Oracle 8i database with a
thin ( type 4) driver.
Note: We have sucessfully deployed this app to Orion, Weblogic & iPlanet
servers.
The relevant entries are
1) In jboss.jcml I have added
<!-- JDBC -->
<mbean code="org.jboss.jdbc.JdbcProvider"
name="DefaultDomain:service=JdbcProvider">
<attribute name="Drivers">oracle.jdbc.driver.OracleDriver</attribute>
</mbean>
<mbean code="org.jboss.jdbc.XADataSourceLoader"
name="DefaultDomain:service=XADataSource,name=mcs">
<attribute name="PoolName">jdbc/mcs_general</attribute>
<attribute
name="DataSourceClass">org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl</attribute>
<attribute name="URL">jdbc:oracle:thin:@test:1521:test</attribute>
<attribute name="JDBCUser">test</attribute>
<attribute name="Password">test</attribute>
</mbean>
2) Our web.xml has the following entry
<resource-ref>
<description>Data source</description>
<res-ref-name>jdbc/mcs_general</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
3) Finally out code is calling the connection like this
try {
if (lookupName != null) {
if (jndiContext == null) { // Double Check Locking
synchronized (lockObject) {
if (jndiContext == null) {
jndiContext = new InitialContext();
}
}
}
DataSource dataSource = (DataSource)
jndiContext.lookup("java:comp/env/"
+ lookupName);
Note: In the above line the variable lookupName evaluates to
"jdbc/mcs_general"
I have used a debugger to try to compare the Context object returned by
JBoss and the object returned by an Orion server but it didn't help.
Any help would be appreciated.
