App Server 8.1 remote acess
Hi,
I am trying to connect to a Sun App Server from the JMS client application: SimpleProducer from chapter 33 of http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
It works fine when run on the same machine where the server is running. But when I try it from a remote machine, I get an infinite chain of error messages beginning with:
Destination name is jms/Queue
May 15, 2003 6:42:02 PM com.sun.corba.ee.spi.logging.LogWrapperBase doLog
INFO: "IOP00710299: (INTERNAL) Successfully created IIOP listener on

at com.sun.corba.ee.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2257)
When the server is local I run this command from the simple/build directory:
#java SimpleProducer jms/Queue
and it works successfully.
From a remote machine I run the below command from the simple/build
directory:
#java -Dorg.omg.CORBA.ORBInitialHost=myservername SimpleProducer
jms/Queue
Sounds that at some point the application is trying to connect to the localhost. Specifying a properties file as below does not help either.
--- jndi.properties ---
java.naming.factory.initial=com.sun.enterprise.naming.SerialInitContextFactory
java.naming.provider.url=iiop://myservername:3700java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
Running those applications to access a local server works fine on both machines. I want to have a client accessing the server remotely. Do I need to edit/compile source code of those applications in some other way? Isn't specifying a remote server from command line enough? I have tried any suggestions found on the Internet or anything coming to my mind but no success so far. I appreciate any clues.
thanks,
Farshad
Apparently, the system tries to connect to the localhost at some point! I changed the jndi.properties to:
java.naming.factory.initial=com.sun.enterprise.naming.SerialInitContextFactory
org.omg.CORBA.ORBInitialHost=myservername
org.omg.CORBA.ORBInitialPort=3700
java.naming.provider.url=iiop://myservername:3700
Now, executing
#java -Djms.properties=jndi.properties SimpleProducer jms/Queue
gives the below message while if I change "myservername" to "localhost" and run an App Server locally it works quite fine. What am I missing?! Isn't it enough to have a remote server name in that jndi.properties to make the same application work with a remote server? I appreciate any help.

Using Office Web Apps Server 2013 without SharePoint, Lync, or Exchange
I'm trying to use the Office Web Apps Server 2013 as an online viewer of Office documents (using the Online Viewer). I've set up a New-OfficeWebAppsFarm with editing disabled, no UNC paths, and an external URL with SSL Offloaded to my Load balancer.
I don't want to use it with SharePoint, Lync or Exchange. Just use it to view documents online (similar to Google Docs Viewer).
However, when I point the Office Web Apps Server to a remote file online (e.x. a DOC hosted on a website), I get an error opening it.
I've checked the health statuses of my OWA Servers, and it says Healthy.
When I check the Event viewer of my OWA Server, I see 501 WOPI errors:
Could not contact WOPI End Point. Error details - 'NotImplemented url - https://sample-owa-url.com/oh/wopi/files/@/wFileId?wFileId=http%3A%2F%2Fwww%2Eimr%2Esandia%2Egov%2Fimrtemplate%2Edoc&access_token=1&access_token_ttl=0'.
It seems OWA is trying to connect to the path /oh/wopi/files.... but the server is responding NotImplemented.
What do I have to get this to work?
Thanks for any help!Did you ever find an answer? I have the exact same Issue.
I have 2 WAC servers behind a load balancer with SSL offloaded to the LB. Both servers report healthy with Get-OfficeWebAppsMachine
Works fine with SharePoint 2013.
When I use it with a remote file, served using HTTP with no authentication (anonymous), I get a generic "Sorry there was a problem and we can't open this document..." error.
In the ULS and event viewer, I see the WOPI error and 501 which basically says:
Could not contact WOPI End Point. Error details - 'NotImplemented url - https://sample-owa-url.com/oh/wopi/files/@/wFileId?wFileId=http%3A%2F%2Fwww%2Blah%2Ecom%2FWordDocument%2Edocx&access_token=1&access_token_ttl=0'.
I also sometimes see this:
<HealthMessage>WordViewerWfeWatchdog reported status for WebWordViewer in category 'WfeRedirect'. Reported status: /default.aspx returned a 404, which means that we didn't have where to redirect.</HealthMessage>
The very interesting part s that I have a dev server, with OWA (WAC) installed, thats not going through a LB and does not use SSL, that works just fine with the same public url word document. -
Good day! Whow can I make a Remote Acess by iPad to another server.
Best regards.
Durval FariaWhat kind of server are you connecting to?
There are many Remote Desktop apps for the iPad. These will let you connect to a Windows server or desktop. There are also an app or two for connecting to a Mac but I have never used them so I'm not sure how they work.
You can also try LogMeIn. It works on just about anything. However, the LogMeIn app for the iPad costs $30. -

Both VM and base machine are in same domain
Installed VS 2013 in my base machine and create a Provided hosted app with the copied certificates, (For creation i followed the above mentioned URL)
Just created and hit F5 to run in my base machine, but getting this error
Error occurred in deployment step 'Uninstall app for SharePoint': The remote server returned an error: (502) Bad Gateway.
Please help me to resolve this issue, trying to figure out from last 2 days
Thanks in Advance
ArunHi Harminder,
This happens because an app has already been deployed and you are deploying it again using the same version.
Resolution:
Open the AppManifest.xml file and change the version.

Provider hosted app error message: The remote server returned an error: (429) Too Many Requests.
Hi,
I have a customer running a provider hosted app and in Sharepoint 2013. Things have been working fine but recently they keep experiencing an issue where the all the app parts on the page show the following error message. Does anyone have an idea what
could be causing this problem and how I can fix it? The Sharepoint site and provider hosted app site are running on a Server 2008 R2 box with IIS 7.5.

Impreza Software DevelopmentHi GuYumming,
I have checked the Sharepoint site using Fiddler and my X-SharePointHealthScore stays consistently on 1, I have even refreshed the site and had the "(429) Too Many Requests" error happen right in front of me whilst Fiddler is running and when I look at the
200 response for the Sharepoint site it is still showing "X-SharePointHealthScore: 1".
I assume because of this I do not need to make any of the changes suggested in your article above?
I have also been through the ULS logs and found the following 3 log entries that appear to relate to the issue but they do not really mean much to me so I am hoping that you can help:

Server 2012 R2 - Remote Apps (RDWeb) and Self Signed Certificates!
Hi all! I have been playing around with VM's on Microsoft Azure just to try and have some Windows Services facing externally that I can play around with and test.
I have spun up a Windows Server 2012 R2 Server and installed Remote Desktop Services on it. I am looking to publish some remote apps and ideally I am looking to get it to work externally.
The Server has been given an IP address which is fine, i have gone to my domain and actually setup cloud.mydomain.co.uk and DNS for this is pointing to the IP address of the server. This is all working and functioning!
Basically if I go onto my server and connect to the RDweb section and login, i can see my remote apps, i can download the laucher and open them, all works great! :)
If however, I go to https://cloud.mydomain.co.uk/RDWeb it asks me to login, I can then see my remote apps but when I click on them I get a certificate stating that the computer cannot verify the identity of the RD Gateway.
What am i missing....what do I need to do to get this to work?
If there is some sort of tutorial on how to set this up, fully, from start to finish then that would be great. Otherwise any advice on this would be muchly appreciated!!
Thanks! :)
#2 sounds like we would need 2 Essentials servers and we will not have that.
We currently have Server 2008 R2 and have 2012 Standard licenses that are not yet used.
We have much more than 75 users total, but 75 is more than the number of users that will probably take advantage of using RD Gateway any time soon. It will probably take time to catch on.
If RD Gateway usage was to get super popular and more than 75 users were depending on access to it, then we could financially justify paying to buy all the CALs needed to run RD Gateway without Essentials. Right now, they are skeptical that it will
be worth spending much money on this and don't want to invest a lot of money up front.
My understanding is that if we have 75 or fewer users using RD Gateway then we need to by no CALs, just apply a Server Standard Edition License to the server, but if we had 76, we would need to turn off Essentials and buy 76 new CALs.
Or would we need to add 50 CALs to the 25 that automatically come with Essentials?
Also does "turning off" Essentials mean we would have to reinstall and redeploy the RDG or is it just a matter of enabling the RD license server and adding purchased CALs?
No, when you buy essentials you get the right to create 25 users that access the server, when you create the 26th user you will need to have 26 CAL and RDS CAL. -
App won't load if remote app server isn't there
I have an application that is using a connection factory to subscribe to a topic on a remote host. If that remote host is not up when i deploy my application, the application will not load. If the app is already running and the remote server goes down, it will just retry to connect to the remote server. My app can still run with out it. So how do I get my app to come up when the remote server is not up and running?? Thanks!
Hi! Thanks for replying back! Here is some more info:
Please provide more information, such as
The type of application, a mdb, servlet, session
bean, appclient .. ?For sake of keeping it simple, it is a MDB on one application server and a publisher on another app server.
How the connection factory is used in the application
?The connection factory is being used from the descriptor files. here is my descriptor file for the MDB (ejb-jar):

so the container automatically sets up the subscription to the topic statusTopic. The TopicConnectionFactory remoteTCF has a imqBrokerHostName set to a remote host, not localhost. So it is subscribing to a topic using a remote broker through that connection factory.
What does the application do ?Again for simplicity sake, all it does is listen for a message to be published to the statusTopic on a remote machine (appserver). There is a publisher on the remote machine that publishes to that topic using a localTCF.
The application server version ?SunOne Application Server 7.0 platform edition (and Messaging Queue 3.01 platform)
Please elaborate on "subscribe to a topic on a remote
host"I think i did this above.
So when i deploy this application, the container sets up the durable subscription for me. Then the app waits for a message to be published.
Now, if the app server that contains the publisher is not running and i try to bring up the app server with the MDB (say after a restart), the MDB application will not load because it cannot connect to the remote host named by the connection factory.
How do I get around this? Thanks for the reply!

What ports need to be open to control Lion Server from a remote location (through Server.app)?
I need to control a Lion Server from a remote location and need to poke some holes in the firewall, unfortunately, I have no idea what ports those need to be. I can control the Server via the Server Admin application, but it will simply not connect via the Server.app.
Suggestions?
Thanks in advance.

Error in downloading jars through jnlp from Oracle 10.1.3 App Server
I am working on migrating an application (containing two WARs) from Resin servlet server to Oracle 10.1.3 App Server. The migration was unit tested successfully. One of the WARs was implemented as a web service that downloaded JARs to the client PC through jnlp. When I tried to combine the two WARs into one (application) WAR, some of the JARs failed to download with an error message stating that they were "corrupted". 5 of the 6 "corrupted" contain native code, although two other native code JARs were able to download successfully.
Most of the time the jnlp failure was accompanied with this error: WARNING: Exception returned by remote server: {0}

Why is the jnlp failing when the WARs are part of the (main) application, but OK when it is part of a web service WAR? How can I overcome this problem?
Thanks for your help.Hi Marc ,
Thanks for your reply.....
Did you mentioning the script (upgrade_10131_
10133_oracle.sql) in the orabpel. I had run this script after applying the patch.
Still iam facing the same issue.
what need to be done?
Could you please help me on this, because I need to do the Fault Handling Framework in BPEL and so i need the faultpolicy folder to be present.
Since I got the folder by applying the patch, but what happend is when i try to check out for the activity status in the BPEL Console Activity tab it is showing the error as mentioned earlier. Any problem with patch implementation or any bug is there. So far i done the patch installation successfully without error and i upgraded the orabpel schema using the mentioned script also. Any other things i need to do?

Office web apps server (2013) certificate issue
If the name of the farm is different from the name of the individual office web apps server machine is there any way to deploy office web apps server with a single domain SSL certificate?
My office web apps server is working, but reporting itself unhealthy, apparently due to the fact that the SSL cert is for the name of the farm and that is different from the name of the machine.
Errors are 2004, 1004, 2156, 1156, "could not establish trust relationship for the SSL/TLS secure channel"
Going to the farm's discovery URL in the browser works fine, but going to the machine name (plus /hosting/discovery) gives an SSL error because the name of the farm is not the same as the name of the machine.
Is there any way to make it use the farm's URL instead of the machine's URL in its own internal watchdog operations? Or any way to make it use a self signed certificate on the machine's URL for it's own health checks and still use the legitimate purchased
SSL cert for user access? Or any other way you can think of to use a $5.99/yr single domain certificate instead of a $89.99/yr multiple domain certificate?
Bill CoulterI am experiencing this same issue. The OWA server has sp1 installed. In the OWA event logs I am getting health fails for 2 events and as best I can tell it seems to be related to this issue.
We are also using a single godaddy certificate with a non machine name FQDN. Both internal and external url's of the OWA farm are set to this same name.
The problem only seems to occur with the 'Proofing Watchdog' (See events below).
Has anyone got any update on whether this is supposed to be fixed ?

Server 2012 R2 Remote Desktop Gateway. Most Simple and Secure Design For Small Environment?
We would like users to be able to connect remotely over the Internet from their personal devices to their primary Windows 7 workstation (a physical box on their desk) by using the Microsoft RDP Client For Windows, Mac, iOS and Android. There is no
plan to use RDWeb or Remote Apps, or VDI. Just plain remote access to their desktop PC without VPN plus a third party 2nd factor authentication product that can text them back a code to enter with their AD credentials (AuthAnvil or Duosecurity)
We do not have TMG or ISA.
We would like to get these services all running in a single server and be as simple as possible while still being very secure.
The recommendations I see seem to suggest putting the RDG in a DMZ with either a domain controller on a new domain with a one-way trust to your internal domain or else a read-only domain controller on your domain and then RD Session Host and License server
located on different servers on your internal LAN.
http://blogs.msdn.com/b/rds/archive/2009/07/31/rd-gateway-deployment-in-a-perimeter-network-firewall-rules.aspx
That sounds like a lot of separate servers and cost for not a lot of users in our environment.
Do we even need a separate session host server if there are no RDP sessions being hosted directly on the servers because the users are only being redirected to connect to their workstations and will never be using terminal sessions on the server?
Can the RODC or the Domain controller on new domain with the one-way trust be the same server as the Remote Desktop Gateway server and not separate servers?
What is the most minimalist way to set this up with good security when opening all the ports needed to authenticate with internal DC is not secure enough?#2 sounds like we would need 2 Essentials servers and we will not have that.
We currently have Server 2008 R2 and have 2012 Standard licenses that are not yet used.
We have much more than 75 users total, but 75 is more than the number of users that will probably take advantage of using RD Gateway any time soon. It will probably take time to catch on.
If RD Gateway usage was to get super popular and more than 75 users were depending on access to it, then we could financially justify paying to buy all the CALs needed to run RD Gateway without Essentials. Right now, they are skeptical that it will
be worth spending much money on this and don't want to invest a lot of money up front.
My understanding is that if we have 75 or fewer users using RD Gateway then we need to by no CALs, just apply a Server Standard Edition License to the server, but if we had 76, we would need to turn off Essentials and buy 76 new CALs.
Or would we need to add 50 CALs to the 25 that automatically come with Essentials?
Also does "turning off" Essentials mean we would have to reinstall and redeploy the RDG or is it just a matter of enabling the RD license server and adding purchased CALs?
No, when you buy essentials you get the right to create 25 users that access the server, when you create the 26th user you will need to have 26 CAL and RDS CAL. -
How to access JDBC Resource registered in Sun Java System App Server ?
I want to create a stand-alone JDBC application with Java SE using Swing technologies and JNDI technology. The purpose of using JNDI technology is to avoid change of Java Source Code every time I move the database to different location. This Java application will be used in a standalone PC installed with Windows XP Professional with no LAN / WAN connection. Of course, Internet connection is available with the PC.
I use JavaDB to store the data tables and the location of the database is D:\E-DRIVE\SAPDEV. Tomorrow, if I move this database to C:\SAPDEV or any network drive, I do not want to change the Java Source code. I want to use JNDI which, if I am not wrong, helps developers to avoid manual change of Java source code whenever the database location is changed. Changes have to be made only in the JNDI Name which contains all relevant information about the database in order to get connection no matter where the database SAPDEV is stored; it can be placed under D:\E-DRIVE directory or C:\ directory of the hard disk. To implement my intention, I started developing Java application as per the steps mentioned below:
Step 1:
To proceed, first, I sought the help of Sun Java System Application Server Admin Console. I created JNDI object for Connection Pool using the menu path Common Tasks->Resources->JDBC->Connection Pools.
JNDI Name : ABAPRPY
Resource Type : javax.sql.DataSource
Datasource class : org.apache.derby.jdbc.ClientDataSource
Description : ABAP Program Repository
The Connection Pool creation has options for General, Advanced and Additional Settings tabs and I made all the settings relevant to the database I created in D:\E-DRIVE\SAPDEV.
To confirm whether the above settings are correct, I pressed the Ping push button which is available in the General tab of the connection pool creation screen. The system responded with the message Ping Succeeded.
Step 2:
I created a JDBC Resource using the menu path Common Tasks->Resources->JDBC->JDBC Resources.
JNDI Name : jdbc/SAPDEV
Pool Name : ABAPRPY
Description : Database Connection for SAPDEV database
Status : Enabled
I can see all the above settings recorded in the domain.xml which is placed in the folder
C:\Sun\AppServer\domains\domain1\config
Step 3:
I have made sure that Sun Java System Application Server is up and running in the background with JavaDB server. I created a Java Program making sure the following JAR files are included in the classpath:
appserv-admin.jar
appserv-ee.jar
appserv-rt.jar
javaee.jar
fscontext.jar
Plus, the lib directory of JDK 1.6 & C:\Sun\AppServer\domains\domain1\config
Source code of the program is as follows: I used NetBeans IDE to create my project file.
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.naming.*;
import javax.activation.DataSource;
public class JNDILookup {
public static void main(String[] args) {
try {
InitialContext initCtx = new InitialContext();
DataSource ds = (DataSource) initCtx.lookup("java:comp/env/jdbc/sapdev>");
} catch (NamingException ex) {
Logger.getLogger(JNDILookup.class.getName()).log(Level.SEVERE, null, ex);
When I attempted to compile the above program in NetBeans IDE ,no compilation error reported. But while executing the program, I got the following run-time error message:
SEVERE: null
javax.naming.NameNotFoundException: No object bound for java:comp/env/jdbc/sapdev> [Root exception is java.lang.NullPointerException]
at com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:224)

at javax.naming.InitialContext.lookup(InitialContext.java:392)
at SAPConnect.JNDILookup.main(JNDILookup.java:21)
Caused by: java.lang.NullPointerException
at com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:173)
... 3 more
Now, I want to come out of this situation; at the same time, I want to preserve the settings I have made in the Sun Java System Application Server Admin Console. That is, I want to programmatically access the data source using Connection Pool created in Sun Java System Application Server Admin Console.
I request dear forum members to provide me an appropriate solution.
Thanks and regards,

Bare in mind I am attempting the context.lookup() from inside the container (my code is in a session bean). I have accessed the server and have my bean "say hello" first to verify the bean works OK, then I call a method with this rather standard code:

You are fine here. It works in container because the InitialContext properties have been supplied already. That was the link I forwarded earlier. The InitialContext you create locally needs to locate the container JNDI. That is what the properties specify.
Where I am confused is where you indicate the stack below is from the server log. So, you initiate a standalone (java main method) application, create an InitialContext, and you see the results in your app server log?
LDR5010: All ejb(s) of [EJB_Module_1] loaded successfully!
Programatically acquiring JNDI DataDource: Second_EJB_Module_DataBase
The log message is null.

This is strange since I can see this resource (a JDBC connection named Second_EJB_Module_DataBase) is configured on the server from the server's admin console.
That is why you can obtain a lookup from within the container (app server).
For this lookup to work it may be that one must map the name inside an ejb-jar.xml deployed with the application, but I have also read some resources like jdbc connection should have a default name. Does anyone know if my lookup() should work without using an ejb-jar.xml mfile to explcitly map the reource for my application?
Both EBJ's and data sources can be referenced via JNDI. It's a remote lookup (that is normally optimized if it is running in the same JVM). You should not have any dependencies on a JDBC data source being set-up on ejb-jar.xml. That file can of course impact your EJB's. However, data sources are normally set-up on a container-specific basis (e.g., you probably did it through a console, but there is a spec somewhere about how to set up a data source via a resource the app server looks for; it varies from app server to app server). However, once you have that container-specific data source set-up, JNDI operates vendor-neutral. You should be able to take the code above and move it to JBoss or Weblogic or Tomcat or whatever (this is an ideal, in practice, the vendors sometimes put a data source in a name you would not expect, but again, you can use their JMX console to see what the JNDI name is).
(As I stated above if I have to use a deployment discriptor to get at this JNDI datasource, then solution is not "programmatic" as newly configured datasources could not be accessed without redeploying the entire application).
As JSchell alluded to, you will always have at least something vendor-specific. JNDI itself (the code you wrote) is totally portable. However, you have to set the various JNDI environment properties to a given vendor's spec. Ideally, you should not need a vendor's actual InitialContext application, but it's a possibility. Once you can safely cast to Context, you should be vendor-neutral (if not, demand your money back).
So that is exactly where I am stuck, trying to get the lookup to work and wondering if it should work without and xml file mapping the resource for my app.
What we ended up doing for standalone was to provide our own JNDI. If you look at the open source project JOTM, there are examples on how to use that with XBean (if integrating with Spring, as we did), you can easily set up a data source that runs standalone exactly as you get in the container. Another benefit is you get full JTA/JTS support and the ability to run XA transactions. (This might all be alphabet soup, but the app server gives it to you, and this is the way we ended up doing the same: JNDI + JTA + JTS + XA). It ends up the same application code uses a "vanilla" InitialContext and all we have to do is write one or two xml files (one for our app server, a couple for JOTM), and our actual code works the same.
I still think you have a shot at getting to the container's JNDI, just not using their full-blown app server JAR.
I think there must be a simple way to do this with an ejb-jar.xml, I am no expert in JNDI, I could be missing something simple, I will keep at it and post an answer here if I come up with it.
Thanks, jayIt is simple to code. Getting it to integrate with your app server, yes, that can be challenging. But it has nothing to do with EJB's. Write a simple test. Using nothing but DataSource and InitialContext. Let us know where you get stuck.

Trying to write a basic EJB app w/ JPA and remote client
I'm trying to put together a simple sample app that shows a simple stateless session bean that grabs a Java EE 5 entity from the DB and sends it to the remote caller. I have an entity class called Person that simply has getId() and getName() methods.
I'm trying to get a reference to the session bean (using InitialContext.lookup()), which works. Then I try to call a method on that bean, which works as long as the type being returned is not a Person object. I've had the bean always return "Hello" and it works just fine.
Here's the bean code.
@Stateless(mappedName="RolodexSession")
public class RolodexSessionBean implements RolodexSessionRemote {
@PersistenceContext
private EntityManager em;
/** Creates a new instance of RolodexSessionBean */
public RolodexSessionBean() {
public Object getPersonByName(String name)
Query q = em.createQuery("select object(o) from Person o where o.name=:n");
q.setParameter("n",name);
List results = q.getResultList();
if (results.isEmpty())
return "emtpy";
// this would work just fine...
// return "Some string";
// but this doesn't work at all
return results.get(0);
}Here's the client code...
public class Main {
@EJB
protected RolodexSessionRemote rolodexSession;
/** Creates a new instance of Main */
public Main() throws NamingException {
Context ctx = new InitialContext();
rolodexSession = (RolodexSessionRemote)ctx.lookup("RolodexSession");
Object result = rolodexSession.getPersonByName("John Smith");
System.out.println(result);
* @param args the command line arguments
public static void main(String[] args) throws NamingException {
Main m = new Main();
}I made sure to put a Person object into my database with the name "John Smith".
The error I keep getting is...

at clientapp.Main.<init>(Main.java:33)
at clientapp.Main.main(Main.java:41)I'm running this on the Sun Java System App Server 9.0.
Any ideas?I've narrowed down the issue. The Person object that I'm trying to send back has a one-to-many relationship with Address objects. I have this all setup correctly, I think. Here's the code from Person.java that establishes that relationship.
* Holds value of property addresses.
@OneToMany(mappedBy = "person")
private List<Address> addresses;
* Getter for property addresses.
* @return Value of property addresses.
public List<Address> getAddresses() {
return this.addresses;
* Setter for property addresses.
* @param addresses New value of property addresses.
public void setAddresses(List<Address> addresses) {
this.addresses = addresses;
}In Address.java I have the other side of the relationship defined (again, correctly, I think).
IF I COMMENT OUT THIS RELATIONSHIP EVERYTHING WORKS! So, the problem seems to be related to using foreign key associations. Is there something I'm missing here? Perhaps it's related to lazy-loading of foreign keys? -
Sun Application Server 8.1 remote deplyment database connection
I use the deploy to Remote server to deply a project to Sun Application Server 8.1. When i try to connect to the database I get connection error
javax.servlet.ServletException: javax.faces.FacesException: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: Access denied for user ''@'testserver.com' (using password: YES)
it seems it doesnt pick the User from the Connection pull settings. The settings at the server seem correct.
This works fine when i deply to Application server 8.0 that comes with the Sun creatorThe user is correct and it does work from 8.0/
The server doesnt pick the username from the
configuration
the error message says use '' emptyWhat "configuration" are you referring to? Do you mean the way that you have the 8.1 server set up?
Since you cannot ping, then there is something wrong with the configuration on the 8.1 server.
Why don't you remove the connection pool and start over from scratch and cut/paste the settings from the 8.0 app server over. Then make sure you can ping once everything is set up.
Also, where is the 8.1 box located? Are you sure it has access to the database that you are trying to reach?
You might try posting this to the App Server forum as it really isn't a Creator problem.
