I'm using the ojdbc7.jar that is distributed from the Oracle site, and so far it has worked perfectly. Recently, however, we've decided to switch to using a maven structure for our webapp development so I've been converting our Java Web App to maven. Now I'm seeing this oracle.jdbc.driver.T4CConnection.isValid(I)Z error when making an Oracle DB connection even though I'm using the exact same driver file as I was in my non-maven build. I have the dependency declared like this:
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc</artifactId>
<version>7</version>
</dependency>
I have manually installed the driver using Netbeans, as the maven depository does not contain the ojdbc7 driver.
Why am I seeing this error and what can I do about it? It's clearly a maven related problem seeing as this builds perfectly without maven managing it.
