File upload and download.
I'm using Tomcat 5.0.28.
My app relates to upload and download.
Using fileupload to upload files,
and a basic file interface to store them
to a fixed disk location.
Presenting a webpage with a list of links,
the url needs to be within the tomcat installation
(security etc).
Question.
How do people find out where the tomcat base
install is, CATALINA_HOME?
My only solution so far is passing a property
when tomcat is launched, and it does seem messy.
try{
String tcHome = System.getProperty("tcHome");
if (tcHome==null || ){
System.err.println("CATALINA_HOME not set");
}else
System.err.println("tc at " + tcHome);
}catch(java.lang.SecurityException err) {
System.err.println("Security Exception"+ err);
}catch(java.lang.NullPointerException err) {
System.err.println("Property not set. Exception"+ err);
}
Any improvements please?
Regards DaveP.

What about System.getProperty("catalina.base") ? or "catalina.home" ?
they are passed to the jvm at startup.. Not sure how if or how you get
access to them.

The following code gets you CATALINA_HOME. I cannot tell if this will
be helpful to you or not. Probably not, but what the heck, David.
Jack
package com.whatever.classpath;
import java.io.File;
import java.net.URL;
public final class Classpath {
public static final String HERE =
Classpath.class.getClassLoader().getResource(
"com" +
File.separator +
"whatever" + File.separator +
"classpath" + File.separator +
"Classpath.class").getFile();
public static final String CATALINA_HOME = HERE.substring(
1,
HERE.lastIndexOf("webapp"));
}
