Hi, Grant.
Main (first) question is:
Improve performance of search in J2EE app.
Problems:
1. In EJB container I can't start Thread.
2. If i use RMI call from EJB container to Lucene app with binds RemoteSearch
- perfomance ten times more then simple Java application.
(sample)
LocateRegistry.createRegistry(1099);
Searcher parallelSearcher = new ParallelMultiSearcher(searchables);
RemoteSearchable parallelImpl = new RemoteSearchable(parallelSearcher);
Naming.rebind("//localhost/multi_searcher", parallelImpl);
contingencies:
- Server works with java 1.4.
- Many ( > 100) call for each client.
- Index less then 10000 documents.
- Index changed very rare.
- can't use MBean as JBoss.
- can't use java 1.5
Second question:
Can i use ParallelMultiSearcher(searchables) in JCA 1.0 as Singleton object
for all clients.
