Using Berkeley With Two Different Environment Simultaneously

Question

I am trying to use Berkeley with two different environment simultaneously in one program. But I am getting an error message of Databases left open. The first environment close with no error but the 2nd environment, having an error like this,
Exception in thread "main" java.lang.IllegalStateException: Unclosed Database: element_primary_key_index\\192.168.150.211\glassfish3\Berkeley\environment\Testing11
Unclosed Database: class_catalog\\192.168.150.211\glassfish3\Berkeley\environment\Testing11
Unclosed Database: element_database\\192.168.150.211\glassfish3\Berkeley\environment\Testing11
Databases left open: 3

Please someone help me with my problem. Thanks in advance.

Hi Mark,
Here is my sample program for the problem:
import java.io.File;
import com.sleepycat.bind.serial.StoredClassCatalog;
import com.sleepycat.je.Database;
import com.sleepycat.je.DatabaseConfig;
import com.sleepycat.je.Environment;
import com.sleepycat.je.EnvironmentConfig;
import com.sleepycat.je.EnvironmentLockedException;
import com.sleepycat.je.SecondaryConfig;
import com.svi.tools.gfs3v10domain.objects.GFS3v10DomainElementData;
import com.svi.tools.gfs3v10domain.objects.GFS3v10DomainElementKey;
import com.svi.tools.gfs3v10domain.views.utils.ElementByPrimaryKeyCreator;
* Read Write Database used for every thing else.
public class MethodsSample implements GFS3v10Database {
     * Environment where the Database resides.
     private Environment environment = null;
     private boolean isClose = false;
     String environmentString;
     * Class Catalog for Stored Classes.
     private static StoredClassCatalog classCatalog;
     * Element Database.
     private static Database elementDatabase;
     * Element Database by Primary Key.
     private static Database elementByPrimaryKeyDatabase;
     private static Database catalogDatabase;
     * Default Constructor.
     public MethodsSample() {
* Alternate Constructor.
* @param homeDirectory Location where the Database is Located.
public MethodsSample(String homeDirectory) {
     environmentString = homeDirectory;
     openEnvironment(homeDirectory);
     openDatabase();
@Override
     * Opens the Read Write Database.
     * @param homeDirectory Location where the Database is Located.
public void openEnvironment(String homeDirectory) {
     EnvironmentConfig environmentConfig = new EnvironmentConfig();
environmentConfig.setTransactional(true);
environmentConfig.setAllowCreate(true);
environmentConfig.setDurability(DURABILITY);
while (environment == null) {
     try {
          environment = new Environment(new File(homeDirectory), environmentConfig);
     } catch(EnvironmentLockedException ele) {
          try {
                         Thread.sleep(500);
                    } catch (InterruptedException e) {
@Override
     * Opens the Database.
public void openDatabase() {
     DatabaseConfig databaseConfig = new DatabaseConfig();
     databaseConfig.setDeferredWrite(true);
databaseConfig.setAllowCreate(true);
catalogDatabase = environment.openDatabase(null, CLASS_CATALOG + environmentString, databaseConfig);
classCatalog = new StoredClassCatalog(catalogDatabase);
elementDatabase = environment.openDatabase(null, ELEMENT_DATABASE + environmentString, databaseConfig);
SecondaryConfig secondaryConfig = new SecondaryConfig();
secondaryConfig.setDeferredWrite(true);
secondaryConfig.setAllowCreate(true);
secondaryConfig.setSortedDuplicates(true);
secondaryConfig.setKeyCreator(new ElementByPrimaryKeyCreator(classCatalog, GFS3v10DomainElementKey.class, GFS3v10DomainElementData.class, String.class));
elementByPrimaryKeyDatabase = environment.openSecondaryDatabase(null, ELEMENT_PRIMARY_KEY_INDEX + environmentString, elementDatabase, secondaryConfig);
@Override
     * Gets the Environment.
     * @return Environment.
public Environment getEnvironment() {
     return environment;
@Override
     * Gets the Class Catalog.
     * @return Class Catalog.
public StoredClassCatalog getClassCatalog() {
     return classCatalog;
@Override
     * Gets Element Database.
     * @return Element Database.
public Database getElementDatabase() {
     return elementDatabase;
@Override
     * Gets Element By Primary Key Database.
     * @return Element By Primary Key Database.
public Database getElementByPrimaryKeyDatabase() {
     return elementByPrimaryKeyDatabase;
@Override
     * Closes Database and then Environment.
public void closeUpload() {
     System.out.println("1st Jar environment closing = " + environmentString);
     elementByPrimaryKeyDatabase.close();
     elementDatabase.close();
     classCatalog.close();
     catalogDatabase.close();
     environment.close();
     isClose = true;
public Boolean isClose() {
     return isClose;
     @Override
     public void closeOthers() {
for the Main:
public class sample {
     public static void main(String[] args) {
          String environment1 = "\\\\192.168.160.184\\glassfish\\berkeley\\environment\\home\\Multiple\\Testing11";
          String environment2 = "\\\\192.168.150.211\\glassfish3\\Berkeley\\environment\\Testing11";
          openCloseEnvironment(environment1, environment2);
     public static void openCloseEnvironment(String environment1, String environment2) {
          MethodsSample forEnvironment1 = new MethodsSample(environment1); //Opens the Databases
          MethodsSample forEnvironment2 = new MethodsSample(environment2); //Opens the Databases
          forEnvironment1.closeUpload();
          forEnvironment2.closeUpload();
// same error happens no matter what sequence for closing
Thank you.
