No Java 2 SDK, v1.4 support for APPLET

[philm]

A client has version 1.5.0_04 of the Java SDK installed, but get's the following message when he tries to run our applet:

No Java 2 SDK, Standard Edition v 1.4 support for APPLET!!

Is it not backwards compatible? I'm trying to avoid the SUN applet plugin if possible.

Cant give a url, but the OS is Win XP, and the browser is IE6.0.2900

Got him to try in firefox aswell, and just gets a blank gray box. Doesn't have the java icon in the system tray either.

Well is that a message that your code generates or an OS message? Does he have a JRE installed?

In IE, let him/her verify if the checkbox at Tools -> Internet Options
-> Advanced -> Java (Sun) -> Use JRE 1.5.0_04 for <applet> is checked (on).

If that checkbox isn't in IE's Advanced list, your client should open the Java Control Panel (I'm not sure in XP, but probably the same as W2K menu Start -> Settings -> Control Panel -> Java). The 'About' button in the General tab should reveal that 1.5.0_04 indeed is installed. Then in the Advanced tab, the checkboxes at '<APPLET> tag support' should be checked (both 'Internet Explorer' and 'Mozilla and Netscape').

Use Sun's testapplet at <http://java.com/en/download/help/testvm.xml> to verify that the JRE has been installed.

When it fails, make sure, like I mentioned in my previous post, that the checkbox in the Java Control Panel -> Advanced -> <APPLET> tag support
-> Mozilla and Netscape is checked (on).

Further, verify in Firefox that the checkbox at Tools -> Options -> Web Features -> Enable Java is on.

OK, thanks for that - it tuns out IE and Firefox thought that he had a different version of the JRE installed than what he actually has.

He has tried downloading the latest version from the Sun site, but gets the message that it could not verify his installation. I think he needs to uninstall Java and reinstall it.

The 1.5 JVM supports the following versions (as shown by aboutlugins in Firefox) :

application/x-java-vm
application/x-java-applet
application/x-java-applet;version=1.1
application/x-java-applet;version=1.1.1
application/x-java-applet;version=1.1.2
application/x-java-applet;version=1.1.3
application/x-java-applet;version=1.2
application/x-java-applet;version=1.2.1
application/x-java-applet;version=1.2.2
application/x-java-applet;version=1.3
application/x-java-applet;version=1.3.1
application/x-java-applet;version=1.4
application/x-java-applet;version=1.4.1
application/x-java-applet;version=1.4.2
application/x-java-applet;version=1.5

What does your clients' Firefox say for aboutlugins?
