RE: Question about detecting version
Hello, Steve Vanspall,
Have you looked at any of these methods?
class javax.servlet.ServletContext
public int getMajorVersion()
- Returns the major version of the Java Servlet API that this servlet container supports.
public int getMinorVersion()
- Returns the minor version of the Servlet API that this servlet container supports.
public String getServerInfo()
- Returns the name and version of the servlet container on which the servlet is running.
http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html
Notice that the "application" variable, implicitly visible in a jsp, is an instance of ServletContext.
=========================
<html>
<body>
<%= application instanceof ServletContext %>
</body>
</html>
=========================
That will print "true" in the browser.
yours,
Julius Davies, Programmer, CUCBC

RE: Question about detecting version
Posted by Steve Vanspall <st...@crmsoftware.com.au>.
Thanks Julius,
That actually helps me with another problem.
However, my main problem here is that Tomcat will not be running.
And that the installer in not a web application running under tomcat.
I was wondering whether tomcat keep it's version number in a file somewhere
Regards
Steve Vanspall
