Oh I'm terribly sorry I miss the line you said "into shared/lib or
shared/classes". Forget that =P
2006/5/22, Corobitsyn Roman <[EMAIL PROTECTED]>:
Hi
Sharing is possible with Tomcat
You must put your objects in shared classloader
For example:
public class ObjectPool {
private static ObjectPool objectPool = null;
private ObjectPool {
// initialize object
}
public synchronized static ObjectPool getInstance() {
if (objectPool == null) {
objectPool = new ObjectPool();
}
return objectPool;
}
}
And then put jar or compiled class into shared/lib or shared/classes
But prevent garbage collection, you must use the -Xnoclassgc start-up
parameter. (set JAVA_OPTS=-Xnoclassgc)
Other solution is adding the following member to a class that is always loaded
in an application:
private ObjectPool objectPool = ObjectPool.getInstance();
I hope this helps
