DataSource getConnection() configuring connection timeout with jndi

Question

I'm having a problem configuring the timeout that is used when establishing a new connection to an Oracle database when using a connection pool.

I'm using DBCP in Tomcat and XML to configure the resource .

In the source code I get a DataSource and connection like this:

DataSource ds = (DataSource) envCtx.lookup("jdbc/anncDB");
Connection conn = ds.getConnection();

This works fine if the IP specified in the url is available. But if it is not available, it takes 3 minutes before getConnection() returns. I need to configure this to be smaller.

I've tried setLoginTimeout() , but that doesn't work. Doing ds.setLoginTimeout() takes 3 minutes before failing.

Any ideas?

You said that you use XML for declaring the resource. So i suppose you have something like that :

<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/javatest"/>

In this case, watch the maxWait attribute. In the documentation , it's specified that it's the hmaximum time to wait for a database connection to become available (10s in the example).

Hope this help
