The java.net.URLConnection will allow you to open files/connections to a url and get input/output streams on them (which you con manipulate using the java.io package). However, you will have to overcome Java's security model - simplistically, a normal applet can only access/make connections to the server from which it was downloaded. There are, I believe ways around this using signed applets and certainly JDK1.2 has a much more complex and flexible security model but I'm not an expert in either of these areas.

This worked for me with Redhat 5.1 kernal 2.2 p133 (overclocked to 150) 32Mb. The JIT compiler seems to crash with any awt code (but seems OK with none awt stuff). You might also try java -green ... - the JIT may work with green threads - I haven't tried this yet. Good Luck Stuart. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Trouble? Contact [EMAIL PROTECTED] In JDK 1.2 (and I beleive later releases of Swing) the swing packages are in javax.swing change import com.sun.java.swing.* to import javax.swing.* Sun say that since swing is no part of the JDK it shouldn't be in com.sun and to allow the code from JDK 1.1.x + swing to move to JDK 1.2 (Java2) they didn't put it in java.swing (since its not part of the JDK for 1.1).
