Error

Question

Hi!

I get this error (like a hundred times) in java console when using the 4.0.1 version in safari (mac os x 10.4, jre 1.5.*).

Exception in thread "AWT-EventQueue-4" java.lang.NullPointerException
at com.enterprisedt.net.ftp.applet.FTPApplet.paint(Unknown Source)

Any clues as to why?

Answer 1

Could you post more of the console's output?

Answer 3

In your History-section for v4.0.0 I read "Default Java version changed to 1.6. ". Does this mean that I can change anything when having clients who only run JRE 1.5?
Or is this simply a case of "We dont support anything below 1.6"?

The reason I ask is because many of my companies clients are still running Mac OS X 10.4, which don't have an official JRE 1.6-version released. And their big company wont allow any installs of anthing else.

On later models of OS X (which have JRE 1.6) and on up-to-date windows-clients we do not see this error.



I also got this other messages yesterday when I was out at the client to test:

Answer 4

I'm sorry, but IntegralFTP only works on Mac OSX 10.5 (Leopard) or later. This is because the Java-to-Javascript interfacing module in Safari were not fully implemented prior to this.

Answer 5

Ok, but I didn't get it to work in firefox 3 on OS X 10.4.11, JRE 1.5.0_16 either.

Do you have any list of what browsers/OS'es that are supported, or something similar?

Answer 6

You can find a compatibility list at http://www.enterprisedt.com/forums/viewtopic.php?p=10058.
