Do I need both Java2 1.3 and Java2 1.4 on HP-UX 11.23

[Bellas-Velidis Ioannis]

Running swlist on my new HP Integrity rx2620 server with HP-UX 11.23 I found that there are installed (factory install) two versions of Java, namelly:
1. Java2 1.3 (SDK and RTE) - B9788AA and B9789AA
2. Java2 1.4 (SDK, SDK addon, RTE, RTE addon) - T1456AA, T1456AAaddon, T1457AA and T1457AAaddon
Do I really need them both or can I safely remove the 1.3 version and keep only the 1.4 ?

Hi,

It depends on your enviroment. If there are no applications or other functionality that use Java2 1.3 you can remove it.

u can remove java2.1.3,
unless if any application specifically requires this.

Its likely you need both versions of Java.

Older versions of Oracle won't work with 1.4 but will work just fine with 1.3

You have to inventory your system and see if any applications need it. You will be surprised, some of the web browsers won't work right with certain versions of java.

Make sure you have it handy for reinstallation if you decide to remove Java 1.3

As A. Clay says, the answer in this case is, "It depends"

Thanks very much for your answers. I'll keep them both for now.
