RE: [Jython-users] Re: JDK 1.1.8 [was JDK Recommendation]

[Don C. <don...@em...>]

to enable the Java console in IE 5
Tools -> Internet Options -> Advanced [Tab]
Go to the Microsoft VM section and check "Java Logging Enabled"
restart IE
There should be a java console menu under the view menu

The security problem with IE is the applet is probably trying to read a
configuration file on the hard drive?  A stack trace may tell you more.

java.util.HashMap is JDK 1.2 use java.util.HashTable
