JRE1.4 with WAS 6.2

[Former Member]

We want to use a jar which is only compatible with Java 1.4.x with SAP WAS 6.2 ( with JDK 1.3.1). If the JAVA_HOME is changed to point to 1.4, the J2EE engine does not start.

Is there any alternative?

What we have done in some of these cases (VERY MUCH case dependent) is that we have converted the 1.4 compatible Jar to be 1.3.1 compatible.

In a number of cases this has worked well as most 1.4 features used are either available as an external lib in 1.3 (for example Regular expressions) or easy enough to replace with some custom work.

At least have a look at this. Start simply by opening the .jar content in Developer Studio and then try to build the library with a 1.3.1 compiler.

Even if you don't succeed you'll have fun trying

Cheers,

Hi,

this is a short one: No.

J2EE Engine on WAS 6.20 is only compatible with JDK 1.3.1. It's a pity, but that's the situation.

Alternatives are only using 6.30/6.40 or changing the source code of your lib to be compatible with 1.3.1.

Hope it helps

PS: I'm really jealous of the developers being free of such restrictions, now able to work with JDK 1.5...
