Meaning which class? <br />
<br />
If you put the driver jar in all lib\ext directories you should be OK if it's the driver class that's the problem.

Apologies... the actual error is an error, not an exception:<br />
<br />
Exception in thread &quot;main&quot; java.lang.NoClassDefFoundE<wbr />rror: java/sql/Savepoint<br />

This is very strange. I had installed 1.4.0, but now I see that the default jre is 1.3.1! I suspect JDev messed it up. I will reinstall 1.4 and get back.<br />

After the failure of a test application, connecting to a remote Oracle database, I am trying to locate the portion of the Java source (generated by JDeveloper 9) that loads the driver and connects to the database. I can find nothing. Is there such code, or does JDev do a lot of hidden work?<br />
<br />
I am asking because I also try to connect &quot;manually&quot;, and the following line of code throws a NoClassDef... exception.<br />
<br />
DriverManager.getConnectio<wbr />n(&quot;jdbc:or<wbr />acle:thin:<wbr />@xxx.xxx.x<wbr />xx.xxx1521<wbr />:EKKE8&quot;, user, pass);<br />

JDBC &amp; JDeveloper

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
