Hi
As you explained I added the <env-entry-name> to the web.xml and tried to
call it in my javabean as below:
-----------------------------------------------------------
Context ctx = null;
try {
ctx = new InitialContext();
} catch (Exception e) {
System.out.println("Couldn't build an initial context : " +
e);
return;
}
String dbuser = (String)ctx.lookup("java:comp/env/dbuser");
------------------------------------------------------------------------------------
but at this point I am getting this error:
javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an
application resource file: java.naming.factory.initial
my web.xml entry is as below:
<env-entry>
<env-entry-name>dbuser</env-entry-name>
<env-entry-value>guest</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
Can you throw some light on this please?
I am using jdk1.4 and tomcat 3.3.1
Thanx in advance
Deepak
