How to delete jdb files at runtime?

Question

My problem description is, i have to do complete index will be performed by creating a new empty index and adding content data to that (working index). Searches will continue to use the old (active) index. Once the index process is complete, the working and active indexes are swapped and the working index can be removed in preparation for the next complete analysis.
How can i remove jdb files at runtime without using java.io.File. ? [ According to the ejb specs an ejb should not try to use java.io package to attempt to access a file ].
Thanks,
Katta.

Hi Charles ,
I have implemented as your suggested way. I removed the old JE Database once new index (separate JE Database) created using env.removeDatabase() method. It's deleted the databse but *.bdb files not deleted(How can i reclaim the disk space). The cleaner is not deleting the files. Is cleaner will work without closing Environment. Do I need to use any methods to delete *.bdb files?
JEConnection jeConnection = null;
Environment env=null;
try
jeConnection = getConnection(OldJEEnvHome);
env = jeConnection.getEnvironment();
Database index, blocks;
index = jeConnection.openDatabase("__index__", null);
blocks = jeConnection.openDatabase("__blocks__", null);
String dbName1 = index.getDatabaseName();
String dbName2 = blocks.getDatabaseName();
Directory indexDir = new JEDirectory(null, index, blocks);
if(index!=null)index.close();
if(blocks!=null)blocks.close();
env.removeDatabase(null, dbName1);
env.removeDatabase(null, dbName2);
} catch (Exception e)
{    // TODO: handle exception
e.printStackTrace();
}finally{
if(jeConnection!=null)
jeConnection.close();
env.cleanLog();
//env.close();
public JEConnection getConnection(String dbEnvHome)
throws NamingException, JEException
EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setAllowCreate(true);
envConfig.setTransactional(true);
envConfig.setConfigParam("je.cleaner.expunge", "true");
InitialContext iniCtx = new InitialContext();
Context enc = (Context) iniCtx.lookup("java:comp/env");
Object ref = enc.lookup("ra/JEConnectionFactory");
JEConnectionFactory dcf = (JEConnectionFactory) ref;
JEConnection dc = dcf.getConnection(dbEnvHome, envConfig);
return dc;
