Application wide variables with Tomcat/Axis

Hello,

I have installed axis on Tomcat and a few WebServices.

My Problem: I want to have a >>APPLICATION WIDE OBJECT<<, which you can
reach from a WebService as well as a Java Application which is running
on this server.

I would like to have something similar to the Session Object on a Web
Page where you can add and remove items.

Scenario:
-------------
The Programm Codes who share a Class called MyQueue, which is a Class
which holdes
all the processes.

WebService1(Pseudo Code)/**Fills Queque with new Datasets*/
  public boolean fillQueue(int GUID, String ProcId){
         MyQueue myqueue = getLivingQueue(); //This function shell give
me the actual queque,

//NOT a new one!!
       MyQueueDataset oneDataSet= myqueue.create() ;//Create a new
DataSet

                            //in the Queue.
       oneDataSet.setProcId(ProcId);
       oneDataSet.setGUID(GUID);
       oneDataSet.setStatus("InQueue");
       ...
      return true;
}

WebService2:(Pseudo Code)/*Find out Status of certain Queque*/
public String getStatusOfGUID(int GUID){
       MyQueue myqueue = getLivingQueue(); //This function shell give
me the actual queque,

//NOT a new one!!
       MyQueueDataset oneDataSet = myqueue.getByGUID(GUID);
       return oneDataSet .status;
}

A Job:(Pseudo Code)/*Try to proceed DataSets which havent proceede
yet*/
Class Watcher(){
int static main(){
....
MyQueue myqueue = getLivingQueue();
while(1==1){
   ArrayList allJobsNotDone =
myqueue.getAllDataSetsWhichAreNotSuccessFullProceedd()
  while(allJobsNotDone.hasNext() ){
       MyQueueDataset notJetSuccesfullProceedeJob =
allJobsNotDone.next();
      //Now we call a function which lets say try to put the values

     //of notJetSuccesfullProceedeJob into a database.
     proceed(notJetSuccesfullProceedeJob );

  }
}
}
}

Is this possible just with Tomcat?
Do I need a Messaging System (JMS) or something?

I would appreciate help very much.

Thanks in advanced,
Peter
