Hi folks,
This is my first attempt at integrating JCS into some of my code, and
I�m getting a strange problem. When I compile some code that uses JCS,
the �JCS.getInstance()� method causes the java compiler to throw an
exception (shown below). The code I�m compiling is very plain (See
below) � it�s based on the bookCache example from the docs. I just
installed Maven V. 1.0 beta 5, and downloaded the JCS source from CVS.
I was able to get everything built and tested, but I�m stumped here.
I�m running Java 1.3.1 on Redhat Linux 7.1.
Anyone have any insight? Thanks a bunch!

import org.apache.jcs.JCS;
public class BookVObjManager {
private static BookVObjManager instance; // instance of itself -
Singleton
private static int checkedOut = 0;
private static JCS bookCache;
private BookVObjManager() {
try {
bookCache = JCS.getInstance("testCache1"); // Exception caused by
this line!!!!
} catch (Exception e) {
e.printStackTrace(System.out);
}
}
