Description

I am running Tomcat apache 6.0 in windows XP. I am trying to access Transient repository.

In very first run, I am able to open and close session for Transient repository. but in the next run, it always throws exception "java.nio.channels.OverlappingFileLockException".

To resolve that issue(workaround) I have to restart the apache server. In case of very first run, I am able to read/write from/to repository.

code snippet used: ( wrapper calls to class to session open and close)

import java.io.OutputStream;
import javax.jcr.Repository;
import javax.jcr.Session;
import javax.jcr.SimpleCredentials;
import org.apache.jackrabbit.core.TransientRepository;
public class jackrabbitPlugin
{
public static Session session;
public static int SUCCESS =0;
public static int FAILURE =-1;
private int isOpened = 0;
public String errMsg;
private Repository repository = null;

public String logout()
{
String retValue = "SUCCESS";
try

{ session.logout(); }

catch(Exception exp)

{ retValue = "Exception:" + exp; }

return retValue;
}
public String login (String user,String password, String RepositoryPath,String workspaceName)
{
String retValue = "SUCCESS";
if(workspaceName.compareTo("")==0)

{ workspaceName="default"; }

try
{
if(IsSessionOpen()==false)
{
System.setProperty("org.apache.jackrabbit.repository.home",RepositoryPath);
repository = new TransientRepository();
session = repository.login(new SimpleCredentials(user,password.toCharArray()),workspaceName);
if(session!=null)

{ retValue = "SUCCESS"; isOpened = 1; }

}
}
catch (Exception exp)

{ String errMsg = "Exception:" + exp; retValue = errMsg; System.out.println(errMsg); ((TransientRepository)repository).shutdown(); logout(); this.errMsg = errMsg; }

return retValue;
}

}
