I see.<br />
I've found an info how classes are found. Here is a quote: &quot;...The JAR archive specified by the -jar option, which overrides all other values. If this option is used, all user classes come from the specified archive.&quot;<br />
<br />
Terrible... Anyway, thanks.<br />

Hi ppl,<br />
<br />
There's an application uses Oracle JDBC driver. When I run it &nbsp;as .class-files thru java &lt;mypackage.myMainClass&gt; it works fine. Now I've made a jar-version of my application. But when I run it as java -jar &lt;myjar&gt; I've got Exception in thread &quot;main&quot; java.lang.NoClassDefFoundE<wbr />rror: oracle/jdbc/driver/OracleD<wbr />river<br />
<br />
My CLASSPATH is the same and it's correct. I'm not sure there's a problem with my jar file, Oracle JDBC driver or something else.<br />
<br />
Just FYI:<br />
J2SDK 1.4.0 under Windows XP<br />
Oracle JDBC drivers (versions 8.1.7 and 9.0.1)<br />

NoClassDefFoundError with my jar-application using Oracle JDBC driver

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.
