adding to the Java Classpath

Hi,

I need to programatically add some jars (not to be deployed with the
project) to the classpath in my web app project.  I think this should
work:
   ClassPath cp = ProjectPath.getDesignPath(pm);
   PathResource pathR = ProjectPath.createResource(fo, project);
   cp.add(pathR);

And I get the following exception:
java.lang.UnsupportedOperationException
	at org.netbeans.spi.java.classpath.ProxyClassPath.add(ProxyClassPath.java:64)
	at org.netbeans.spi.java.classpath.ProxyClassPath.add(ProxyClassPath.java:65)

If I change getDesignPath to getBasicPath, it works, but my reading of
design path sounds more like my jars: jars which are used at compile
time, but are already deployed in the server.  Should I be using the
basic path?

Also, ClassPath.add says that it will only add the resource if it's
not there already, but by jars keep getting added anyway.
