Steve,
Here's a method which should work. Make sure Tomcat's
"$TOMCAT_DIR/server/lib/catalina.jar" file is in the classpath of whatever java
program is executing this code! "ResourceBundle" comes from the "java.util" package.
=======================================
public String getTomcatVersion()
{
String serverInfo = "doh!";
try
{
ResourceBundle bundle = ResourceBundle.getBundle(
"org.apache.catalina.util.ServerInfo" );
serverInfo = bundle.getString("server.info");
}
catch ( Exception e )
{
// either catalina.jar is not in classpath, or Tomcat team has changed things
around!
}
return serverInfo;
}
=======================================
Alternatively, you could unzip "catalina.jar" and look for this file:
"./org/apache/catalina/util/ServerInfo.properties".
yours,
