使用Websphere在Java中读取环境变量 [英] Read a Environment Variable in Java with Websphere
问题描述
我对Websphere应用服务器7.0(WAS7)和环境变量的阅读有一点问题。
I've a little problem with Websphere application server 7.0 (WAS7) and the reading of Environment Varaibles.
使用TomCat,我已将变量定义为
With TomCat, I've defined a variable as
<Environment name="myVar" type="java.lang.String" value="myVarOnServeur"
我在initialContext上查找了它:
and I read it with a lookup on the initialContext :
Context ctx = new InitialContext();
String myVar = (String) ctx.lookup( "java:comp/env/myVar" );
它确实有效!
但是Websphere,我在GUI上定义了一个环境变量,但我无法在我的java代码中读取它。我有一个NamingException。
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.

如何解决我的问题呢?
推荐答案
我没有看到任何说明可以通过ctx.lookup(java:comp / env / ...)读取这些条目的内容);
I don't see anything there that says that those entries can be read via ctx.lookup( "java:comp/env/..." );
