Hello. I have a question about loading JAR files. It is not necessarily specific to Tomcat, i.e., it is really a generic Java question, but my application happens to be a servlet running under Tomcat 3.2.1. The question is this: Is there a way for a servlet running under Tomcat 3.2.1 to dynamically load specific versions of JAR files independent of what is specified in the CLASSPATH, so that all references to classes implemented in these JAR files (but possibly implemented in other JAR files contained within the CLASSPATH) are guaranteed to be resolved by classes contained within the specific, dynamically loaded JAR files and not from some other JAR files specified in the CLASSPATH. I am looking for a Java facility for JAR files which is analogous to dynamically loading C and C++ libraries on Sun Solaris using dlopen or on Windows using the Win32 API function LoadLibrary. Can it be done with the java.lang.ClassLoader or some other standard classes? Can someone point me to some sample code which demonstrates how to do this? Thanks. Barry Draper [EMAIL PROTECTED]
