What OS version supports Java J2SE JRE, can Jaguar?

[Janit]

I am using a Wallstreet G3 300 running OS 10.2.8 with 288 MB RAM and the latest version of Firefox.

I need to print postage through PayPal and the pop-up window says I need Java J2SE JRE (ie the Java 2 runtime environment).

I only have this issue for Priority Mail International labels -- the older interface for printing USPS domestic labels doesn't need this and still works fine for me. The PMI product is new since May, and I guess they used newer software to write it.

Which version of OSX supports the Java 2 runtime environment? I looked for upgrades/updates at Apple, and for Jaguar they just have a Java 1.4.1 Update 1 for Mac OS X. I installed it, but it doesn't help. I also found the Java EE 5 SDK Update 3, but this appears to be an update for an enterprise edition that I don't have (of course).

The last time this happened to me, I was able to get a friend to print the postage from a machine running Tiger, but I don't have this option today.

Even the computers at my public library apparently don't have Java 2

Any help? If I can't print it out by 6PM, I will have to void the label and pay real money at the Post Office.

Thanks.

Sounds like what you may need to do is turn Java on in FireFox.
Go to Preferences and click the 'Content' tab.

Java is built-in to OS X.
It is dependent on which version of the OS you are using.
AFAIK, it cannot be installed independently of the OS.

All Java in OS X is Java Runtime Environment 2, even if the version of the Virtual Machine says it is 1.x.

HTH.

I double-checked -- Java is turned on.

The PayPal pop-up window for domestic postage displays the postage label image just fine.

The pop-up for Priority Mail International fails to display any image and tells me I need the Java 2 runtime environment, and to download Java J2SE JRE.

If I turn off Java in Firefox preferences, then the pop-up windows don't appear for either type of label, which means that both labels do require some version of Java.

All references to Java 2 on the Apple web site do so in the context of OS 10.4. References to Java updates etc for OS 10.2 or 10.3 mention Java but not Java 2.

If the environment run by Jaguar really IS Java 2 then it's still missing something necessary to print the PMI label. Most likely the PMI label is badly coded.

I sent an email to PayPal asking them to troubleshoot their newer USPS labels on older systems so that they won't loose significant revenues from their behind-the-cutting edge customers.

Feh!

Java 2 is simply a marketing term which has been around since 1998 -- way before OS X 10.0.

Not that this helps you I'm sure, as it is possible that your applet needs a later minor version
of the Java 2 runtime than 10.2 provides, which is Java 1.4.1, whereas Panther has 1.4.2.

You will find this out if you type java -version in a Terminal Window:

$java -version

java version 
1.4.2_12
Java™ 2 Runtime Environment, Standard Edition (build 1.4.2_12-270)

Java HotSpot™ Client VM (build 1.4.2-70, mixed mode)
