Hi,
I am porting a J2EE app to Tomcat 4.0. However I keep getting a null for my
datasource retrieval. I am not sure if Tyrex datasource would do the job.
Or do I need to create my own Oracle datasource. I should not have too but
who knows.Any help would be appreciated.
I have the Classes12.zip and jdbc2_0-stdext in the \lib directory.
I have the following in my server.xml for Tomcat 4.0.
<!-- Power Context -->
<Context path="/PowerSouthin"
docBase="PowerSouthin.war" debug="0" reloadable="true">
<Logger
className="org.apache.catalina.logger.FileLogger" prefix="Power_log."
suffix=".txt" timestamp="true"/>
<Resource name="jdbc/OracleDB"
auth="Container" type="javax.sql.DataSource"/>
<ResourceParams
name="jdbc/OracleDB">
<parameter>
<name>user</name>
<value>xxxxx</value>
</parameter>
<parameter>
<name>password</name>
<value>xxxxx</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>driverName</name>
<value>jdbc:oracle:thin:@xxx.xxx.xxx.xxx</value>
</parameter>
</ResourceParams>
</Context>
I have the following in my web.xml for my application:
<web-app>

I am getting the following console output:

My JDBCSource.java is:
try {

System.out.println("----> In Try");
}
//InitialContext ctx = new InitialContext();
Context ctx = new InitialContext();
if (DEBUG_ON) {
System.out.println("----> ctx is: "+ ctx);

if (DEBUG_ON) {

}
synchronized (ctx) {
if (DEBUG_ON) {
System.out.println("----> have the initial context");
}
String dataSourceName ="jdbc/OracleDB";
if (DEBUG_ON) {
System.out.println("----> dataSourceName ="+ dataSourceName);
}
//m_jdbcSource = (DataSource) ctx.lookup(dataSourceName);
m_jdbcSource = (DataSource) envCtx.lookup(dataSourceName);

}
sErrorMessage = e.toString() +" " + THIS + ", method:

ls.logError(sErrorMessage);
} // catch
