Stateless Session Bean in Websphere

[Sri Rangan]

1)Is there any way to make sure (in websphere3.5) to have always only one particuler stateless session bean instance in the container?
2)Is it possible to set one particular Stateless Session to have highest time out period. Sample deployment descriptor for one stateless session bean which we are using looks like this..(We use ANT for this)
//////////////////////////////////
<buildDeploymentDescriptor <br /> appServer="${appServerName}"<br /> descriptorFileName="${descriptorFileName}"<br /> <br /> beanName="com/TestSessionBean.ser" <br /> timeOut="0"<br /> stateManagement="STATELESS_SESSION"<br /> homeInterface="com.TestSessionBeanHome"<br /> remoteInterface="com.TestSessionBeanService"<br /> enterpriseBean="com.TestSessionBeanBean"<br /> JNDIName="${ejbQualifier}TestSessionBean"<br /> transactionAttribute="TX_REQUIRES_NEW" <br /> isolationLevel="READ_COMMITTED" <br /> runAsMode="SYSTEM_IDENTITY" <br /> dependency1="com.TestSessionBeanHome"<br /> dependency2="com.TestSessionBeanBeanService"<br /> dependency3="com.TestSessionBean"<br /> />
///////////////////////////////////
If you look at the descriptor, the timeout setting is =0. Does it mean that once this statless session bean instance served one cleint request, it would be removed by container from pool?
Is there any maximum limit time for this "timeout". Our requirement is to keep this instance of this one session bean as long as possible.
Thanks
