+This sample runs in Weblogic 5.1 as a servlet.
+
+1. Compile this file (make sure you have jdk1.2 installed or the
+   javax.servlet.* classes in your classpath).
+2. Make sure the weblogic policy file allows native access. The easiest
+   way is to replace the contents with this:
+
+grant codeBase "file:d:/weblogic/-" {
+  permission java.security.AllPermission;
+};
+
+grant codeBase "file:/c:/classes/-" {
+  permission java.security.AllPermission;
+};
+
+
+grant codeBase "file:${java.home}/lib/ext/-" {
+  permission java.security.AllPermission;
+};
+
+grant { 
+  permission java.security.AllPermission;
+};
+
+3. Add the servlet to the weblogic.properties file:
+
+weblogic.httpd.register.JacobScript=JacobScript
+
+4. Either add your CLASSPATH to weblogic.classpath in startWebLogic.cmd
+   or copy the com directory into weblogic/myserver/servletclasses
+
+5. Copy the jacob/samples/servlet/* into weblogic/myserver/servletclasses
+6. Start weblogic
+
+7. Type the url: http://localhost:7001/JacobScript into the browser
+   (If you run on port 7001)
+
+8. Enter a VBScript expression like:
+   1+2
+   Now
+   "hello" & " world"
+   etc.
+   and watch the MS Script control (which you must have installed)
+   evaluate and return the result.
