It's not MyClass that can't be found, it's a failure to create the anonymous
inner class:
timer.schedule(new TimerTask(){
public void run(){
timer.cancel();
}
}, 60*1000);
The TimerTask definition (interface or superclass) must also be available in
the manager app's classpath (i.e., WEB-INF/lib or WEB-INF/classes).

Re: Cannot create object of class
Hi, it seems that catalina was trying to find your MyClass in her manager's
classpath java.lang.NoClassDefFoundError:
org/apache/catalina/manager/MyClass$1.
Make sure your class path is correct. A faster way to test if to write a
simple jsp and run your thread inside
% ... %. You can need configure your system to give tomcat permission to
run process or executable files...

i belive it has something to to with the timer i use in the class:
public class MyClass implements Runnable{
public void run(){
final Timer timer = new Timer();
timer.schedule(new TimerTask(){
public void run(){
timer.cancel();
}
}, 60*1000);
}
public void startUpdate(){
try{
System.out.println(do something);
Process p =
Runtime.getRuntime().exec(TomcatPath.getAbsInstPath
()+update/check_for_updates.exe);
}catch(Exception e){
}
}
}
dont know what do to since i need the timer task and i need it in a
separate thread...

Re: Cannot create object of class
try to call your time in a single jsp file. say test.jsp ...
%@ page import=yourtimerpath %
%
... I am calling my timer here
%
See if you can make it work ...
