I have a servlet and in this servlet i have a private PojoCache like this:
private PojoCache cache = null;
//Servlet init
public void init() throws ServletException {
super.init();
// Get an instance of PojoCache
try {
cache = createCache("Test-Cluster");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
// Create PojoCache method
private PojoCache createCache(String name) throws Exception {
PojoCache tree = new PojoCache();
PropertyConfigurator config = new PropertyConfigurator();
// read in the replSync xml. Here we use synchronous mode
replication.
config.configure(tree, "META-INF/replSync-service.xml");
tree.setClusterName(name); // We can set a different cluster
group.
tree.start(); // kick start the cache
return tree;
}
when i put console in console something like this: ant deploy
and later run my servlet the cache work fine but if put in console ant undeploy
deploy without restarting JBoos a get this error:
GMS: address is newton:1047
