How to point the classpath to "CLASSPATH" system variable?

Question

Hi Experts!
I'm trying to create a web dynpro application for sending a simple email using the tutorial that can be found here.
I was actually able to make the program work using Java Swing, but not in my web dynpro implementation.
According to the tutorial, the jar files should be located at "CLASSPATH" system variables to make things work.
When I tried printing the URL of the classpath of the web dynpro app, it is pointing to a different location from what I have defined in the system.
I have created the "CLASSPATH" system variable at "C:\CLASSPATH\lib" with the jar files on it. Here's the correct classpath using my swing application:
/C:/CLASSPATH/lib/commons-beanutils-1.8.3.jar
/C:/CLASSPATH/lib/commons-codec-1.4.jar
/C:/CLASSPATH/lib/commons-collections-3.2.1.jar
/C:/CLASSPATH/lib/commons-configuration-1.7.jar
/C:/CLASSPATH/lib/commons-digester-1.8.1.jar
/C:/CLASSPATH/lib/commons-httpclient-3.1.jar
/C:/CLASSPATH/lib/commons-lang-2.6.jar
/C:/CLASSPATH/lib/commons-logging-1.1.1.jar
/C:/CLASSPATH/lib/ewsjavaapi-1.1.5.jar
/C:/CLASSPATH/lib/javamail-ews-bridge-0.0.8.jar
/C:/CLASSPATH/lib/jcifs-1.3.15.jar
/C:/CLASSPATH/lib/mail-1.4.jar
/C:/CLASSPATH/lib/slf4j-api-1.6.4.jar
But the web dynpro app is pointing at different directories.
@Printing project classpath...
/E:/usr/sap/GOS/J03/exe/jstart71.jar
/E:/usr/sap/GOS/J03/exe/sapjvm_5/lib/jvmx.jar
/E:/usr/sap/GOS/J03/exe/sapjvm_5/lib/jvmx_tools.jar
/E:/usr/sap/GOS/J03/exe/jre/lib/iqlib.jar
/E:/usr/sap/GOS/J03/exe/sapjvm_5/lib/tools.jar
/E:/usr/sap/GOS/J03/j2ee/cluster/bin/boot/sap.com~tc~bl~jkernel_boot~impl.jar
/E:/usr/sap/GOS/J03/j2ee/cluster/bin/boot/jaas.jar
/E:/usr/sap/GOS/J03/j2ee/cluster/bin/system/sap.com~tc~bl~bytecode~library.jar
/E:/usr/sap/GOS/J03/j2ee/cluster/bin/boot/memoryanalyzer.jar
This is the code I used for printing the classpath:
ClassLoader cl = ClassLoader.getSystemClassLoader();
URL[] urls = ((URLClassLoader) cl).getURLs();
for (URL url : urls) {
    System.out.println(url.getFile());
How can I set the correct classpath to the "CLASSPATH" system variable?

Erwin,
You wil need to add the jar files to a Library DC and then reference them in your Web Dynpro app.
Take a look at this tutorial
