Read a Environment Variable in Java with Websphere

Question

I've a little problem with Websphere application server 7.0 (WAS7) and the reading of Environment Varaibles.

With TomCat, I've defined a variable as

<Environment name="myVar" type="java.lang.String" value="myVarOnServeur"

and I read it with a lookup on the initialContext :

Context ctx = new InitialContext();
String myVar = (String) ctx.lookup( "java:comp/env/myVar" );

and it works!

But with Websphere, I define a environment variable on the GUI but I can't read it in my java code. I've a NamingException.

How can I do to fix my problem?

Answer 1

On WAS follow the above setting where name is your key and value is your property value. in my example i used Name : Test Value : This is the test value. After setting this values restart your application server. on your Java code call System.getProperty("TEST") where test is the name for your property and the value will show

You are looking at the wrong place.

You should add the variable in Environment->Naming->Name space bindings->New.

If you choose Binding type String, "Binding identifier" and "Name in namespace..." myVar, you can get variable's value with:

Context ctx = new InitialContext();
String myVar = (String) ctx.lookup( "cell/persistent/myVar" );
