A transaction sticky load balance policy allows a remote client to choose a target server node from a server cluster to provide a transaction service. The load balance policy directs invocations of business methods within a transaction to the same target server node. The remote client receives the load balance policy from a proxy, which is downloaded to the remote client from one of the server nodes in the server cluster. The remote client selects a target server node according to the load balance policy. The remote client then invokes the business methods within a transaction on the target server node via the proxy. The target server node can execute all of the business methods within the transaction on a Java virtual machine. The business methods can be implemented with Enterprise JavaBeans (EJBs).
