JDK backward compaitability in WebSphere 6.1

[Arockia Raj]

Hi All,
We are migrating our application to WebSphere 6.1 which has jdk1.5 as runtime environment.Our application is compaitable with jdk1.4.02 and we need to run this application in WebSphere 6.1 by providing backward compaitability for jdk1.5.

Kindly let us know how to configure the application to run with jdk1.5.We are compiling our application in jdk1.5 with backward compaitability to jdk1.4.

When you use Websphere 6.1 it will run your application under Java 5. There isn't any configuration possible, or necessary. If you wrote your application so that it would also run under Java 1.4 that is nice but irrelevant in this case.

Hi Paul,
Thanks a lot for your quick response.

We will compile our application in JDK1.5 with backward compaitability to jdk1.4.If we deploy this application in websphere 6.1,do we face any problems..

Of course there are all sorts of potential problems. But Websphere 6.1 runs applications under Java 5, so if you compile your application under Java 5 then you shouldn't have any problems related to the compiler level.

I do not think ...you will have a probelms with JDK1.4 ...

The only problems you will see with your app ex : webservices , java code ...

Ex : in your app code if you have any word like enum , then this class won"t compile in 5 because this is a key word in jdk1.5..so you need to change the code ..in order to compile ...

i bet you will see lot of application problems and may need to update thirdparty jarsssssssssss
