ServletContext is not replicated. It is the HTTPSession which is replicated when I talk of Containers that support clustering.



depend on the vendors whether ServletContext will be replicated or not.

in case of orionserver if u define <repicate-servlet-context="true"> in orion-web.xml then ServletContext will replicated.that class which is using ServletContext should be implemented serializable class.

in case of oracleappserver


orion-web.xml if u define <cluster-config> then ServletContext and session will be replicated .

i am using oracle app server10.1.2

in home instance i am deploying ear.its running on default port 80.default Oracle HTTp server is running in app server. this OHS will run on default port.


i am deploying another ear in that home instance.i want to run that application in 9999.

so one application should run on http://host:80/yourapp/index.jsp
and other application should run on http://host:9999/yourapp/index.jsp

previoulsy i used oc4j standalone appserver .there i created different instances.each instance will run on different ports.

Is it possible when u use app server.

This article describes the types of session persistance. In is written for WebLogic, but the advantages/disadvantages/types are the same. Conceptually, this is all very similar.



may i know why oracle has not given document abt this session persistent types?

i searched in oracles.i didnt find anything abt this.

r u sure session persistent types are also same for oracle

Is this correct to find out the size of the object in session ??am i doing wrong?

i am using HttpSessionAttributeListener interface to get size of the object in session.


private int getAttributeSize(HttpSessionBindingEvent sbe) {
try {
ByteArrayOutputStream bao= new ByteArrayOutputStream();
BufferedOutputStream bos= new BufferedOutputStream(bao);
ObjectOutputStream oos= new ObjectOutputStream(bos);


String attributeName= sbe.getName();
oos.writeObject(sbe.getSession().getAttribute(attributeName));
oos.flush();

int size = bao.size();
return size;
}catch(Exception exp){
return 0;
}
}
