I am trying to use a datasource to access an Oracle database (Tomcat
5.5.9 and Oracle 9i). I have configured a datasource in the context.xml
as follows:
<?xml version="1.0" encoding="UTF-8"?>
<Context
reloadable="true">
<Resource
name="jdbc/reportdb"
type="javax.sql.DataSource"
url="jdbc:oracle:thin:[EMAIL PROTECTED]:1521:rep"
driverClassName="oracle.jdbc.OracleDriver"
password="rep123"
maxActive="4"
maxWait="5000"
maxIdle="2"
username="rep"/>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
In web.xml I am referring to the datasource as:
<resource-ref>
<description>The Reports DataSource</description>
<res-ref-name>jdbc/reportdb</res-ref-name>
<res-type> javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Unshareable</res-sharing-scope>
</resource-ref>
The code for creating connections is something like this:
try {
Context ctx = (Context)(new InitialContext().lookup("java:comp/env"));
DataSource ds = (DataSource)ctx.lookup("jdbc/reportdb");
Connection con = ds.getConnection();
} catch (NamingException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
The Oracle JDBC driver, classes12.jar is in common/lib.
At runtime I get the following error:
java.lang.NullPointerException
org.apache.tomcat.dbcp.dbcp.DelegatingConnection.close(DelegatingConnection.java:151)
org.apache.tomcat.dbcp.dbcp.PoolableConnection.reallyClose(PoolableConnection.java:95)
org.apache.tomcat.dbcp.dbcp.PoolableConnectionFactory.destroyObject(PoolableConnectionFactory.java:301)
org.apache.tomcat.dbcp.dbcp.BasicDataSource.validateConnectionFactory(BasicDataSource.java:883)
org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:851)
org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:540)
gaim.ui.report.action.ShowReport.doPost(ShowReport.java:42)
Has anyone encountered a similar problem and know of a solution? Is
there anything I am missing in my configuration?
Thanks and Regards,
