Unable to get database instances

Question

I have a custom Java plugin that I had to migrate to a new server. I'm assuming I am missing some configuration somewhere that was present on the old server.
I am getting this error: com.primavera.integration.client.ClientException: Unable to get database instances.
I have tested the "demogeneral.cmd" and it seems to login to the database just fine.
I'm not quite sure what else to test now.

Answer 1

Not sure if your plugin is running local or remote but I have used this to test remote connections.
import com.primavera.integration.client.Session;
import com.primavera.integration.client.EnterpriseLoadManager;
import com.primavera.integration.client.RMIURL;
import com.primavera.integration.client.bo.object.Activity;
import com.primavera.integration.common.DatabaseInstance;
import com.primavera.integration.client.bo.BOIterator;
import com.primavera.integration.client.bo.object.Project;
import java.util.ArrayList;
public class Main {
public static void main(String[] args) {
Session session = null;
String host = "Bavaria";
int port = 9099;
String user = "admin";
String password = "password";
String databaseName = "P6Demo";
String databaseId = "";
try
DatabaseInstance[] dbInstances = Session.getDatabaseInstances( RMIURL.getRmiUrl( RMIURL.STANDARD_RMI_SERVICE, host, port ));
for (DatabaseInstance dbInstance : dbInstances ) {
                    System.out.println(dbInstance.getDatabaseName());
                    System.out.println(dbInstance.getDatabaseId());
                    System.out.println();
                    if (dbInstance.getDatabaseName().equals(databaseName)) {
                         databaseId = dbInstance.getDatabaseId();
               if (databaseId != "") {
                    session = Session.login( RMIURL.getRmiUrl( RMIURL.STANDARD_RMI_SERVICE, host, port ), databaseId, user, password);
                    System.out.println("Logged In");
catch ( Exception e )
System.out.println(e.getMessage());
finally
if ( session != null ) session.logout();
}
