WSAD and JDK 1.4

[Niral Trivedi]

Hi All,

Can anybody tell me which version of WSAD works with JDK1.4? I am using WSAD 5.1.0 and I was able to change the JRE to 1.4 by going in to Windows->Preferece->Installed JRE. But that will work only at compiler level. Still if I start my local WSAD server, it says its using JRE1.3.1_02. I found some posting saying I can not change it. So, now if I want to upgrade to newer version, will WSAD 5.1.2 work?

Thanks all in advance.

Niral,
You are correct that changing the Java version of the server is not supported. RAD 6 (WSAD was renamed RAD) supports Java 1.4.

WSAD 5.1.2 and WAS 5.1 is also supporting the JDK 1.4
For this go to D:\WAS51\AppServer\java\bin and run "java -version" commnad.
