Plz tell me best procedure to administor Sun Java sys Messaging server

Hi there,
I am working on Sun java sys messaging server( am new stuff) .Can you tell me the best approach from your expirience how to manage (Administor Sun java messeging server which uses LDAP directory server).please if possible daily check procedures including commands.
hope hear you soon,
best regards
[email protected]

There's very little daily stuff to do. You will need to monitor disk usage, to make sure nothing runs out of space. Areas that grow include the mail store itself, the mboxlist directory (check for number of transaction logs, files with the name starting with "log"), and the log directory. Most of the log files "rotate", and so won't grow, except the "mail.log" file.
Every day, we take the "mail.log_yesterday", and add it to the "mail.log". We then take the "mail.log_current", and move it to replace the "mail.log_yesterday". And start a new "mail.log_current". We never purge the "mail.log". It's up to you to handle that, occasionally.
Other than checking for disk space, Messaging Server pretty much just runs.

Migration from Sun Java System Portal Server to the Oracle Portal

Hi, I'm in charge of evaluate the viability of a project that comprises the migration from Sun Java System Portal Server to the Oracle Portal. so I'm wondering if there is a kind of out of box migration tool in Oracle Portal or exists some guidelines to do the migration. In the other hand there is the option of migrate from Sun Java System Portal Server to Oracle WebCenter?
Thanks in advance!

The migration path for Sun Portal Server is Oracle WebCenter Suite. WebCenter is a significantly different architecture so there are no tools planned for the migration. However, we do plan to document and publish a whitepaper once we've assisted a few of the initial customer migrations.

Using Sun Java System App Server Update 1 with JDK1.5's XML

Hi,
I have some new code that uses new XML features from JDK 1.5,
e.g., the Validation API.
However, this code fails to run on Sun Java System App Server Update 1,
since the server uses the 'endorsed' mechanism to load outdated XML libraries.
When I remove the outdated XML JAR's from the server's 'endorsed' directory,
the server fails to start....
I would really like to keep using the new XML features....

Where are you placing your jars? I would bundle them with your application. Do not replace the system jars.
There were some package changes to avoid collisions that I believe made jswdp 1.4 and sjsas 8.1

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 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,
K. Rangarajan.

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.

at com.sun.corba.ee.impl.orbutil.threadpool.ThreadPoolImpl$WorkerThread.run(ThreadPoolImpl.java:555)
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.

SetConnectTimeout Doesn't Work in Sun Java System App Server EE 8.1

Hi all,
I have a code that sends a request through HTTP using HttpURLConnection. Roughly, the code is as follows.
HttpURLConnection huc = (HttpURLConnection) url.openConnection();
huc.setConnectTimeout(10000); // 10 seconds.
....I tested it in a normal Java console program and it was working fine. I tested it again inside a servlet using Tomcat and it was okay. But when I tested in a servlet using Sun Java System Application Server, it didn't work. I reckon there must be some configuration that I need to set in Sun Java Application Server, but I just don't know where. I've been googling it for few days with no answer :( Do you guys have any idea about this?
Thanks in advance.

Does anyone have SSL working with the Sun Java System App Server PE?

We have been having problems (to say the least) getting SSL to work with the Sun Java Application Server 8.1 Platform Edition.
We have a signed certificate from VeriSign and have it imported correctly, but when you test it by going to https://localhost:8182/ (note that 8182 is the port set up for SSL) you get a warning mesage saying that the certificate cannot be verified. When you view the certificate you see that it is the one that got automatically generated for you by the app server and not the one we purchased from VeriSign.
So, I was just wondering if anyone out there has gotten this to work and if so, what document did you follow to tell yoiu how it was done!
THANK YOU!

once apon a time i had a real problem with the same issue.. best of luck.. i forget now how to fix.. sorry.

Firebird connection pool on Sun Java System App Server 8.0.0_01

Hello everybody!
I�ve tried (without success) to make a Firebird connection pool (of type "javax.sql.ConnectionPoolDataSource") on Sun AS 8.
I�ve used "org.firebirdsql.pool.FBConnectionPoolDataSource" class (and I�ve tried also the other classes from the "firebirdsql-full.jar" package that�s included in Firebird 1.5.0 JDBC Driver distribution).
Things appear to be OK, but I never get a response after ping-ing the resource...and this not OK, for sure...
I might mention that any other connection pool that I�ve done (mysql, oracle, db2, mssql) works fine.
Any thoughts?
Thank you.

The answer is yes. I can connect without a pool, through DriverManager.getConnection(...) and so on...
Also, the config information for the pool conforms the driver docs. The strange thing is that I can register a Firebird DataSource with the "fscontext" JNDI provider, and I can lookup the registered DataSource...

Webservice Connection Timeout Error in Sun Java System Application server

I have a java code to connect to Ebay Shopping Webservice that uses the client stub generated through Axis. The code works fine when I run it from the main method of a stand alone Java application. Which means there is no issue with the Proxy settings or any other network setting that could block the webservice from my system. However when I use the same code inside a JSF based Web Application, a connection timeout error comes up. The Web application is deployed on the Sun Java System Application server. The stacktrace of the exception is

The JDK version on my machine is 1.5.0_14. Can somebody point me as where I should be looking for errors?

You need to delete all the files under the 'generated' directory to force the server to recompile them after the JDK upgrade. Also check in domain.xml and make sure the JVM parameter is pointing to the JDK that you have installed. It is also worthwhile to check asenv.conf to see which JDK that file is pointing to as well.

Connect from SAP gateway to RFC server failed - Java StandAlone app X SAP RAC System

Dears,
I'm developing a Java application (RFC SERVER) with JCo3 and I need to connect to SAP RAC system.
I have configured the TCP/IP connection via transaction SM59, but when I try to start my server I face the error below (dev_jco_rfc.trc):

This problem happens when my app executes the line:

jco.server.repository_destination=VSPAGUE
Using SAP Logon i can connect to server cpe1601 system E16 without problems.
Please, I really need some help, because my knowledge on SAP platform is minimum.

Hi Markus,
Changing ASHOST=ld7624.dmzwdf.sap.corp as you have suggested, I got the error message: Connect to SAP gateway failed ...
As you could see, the host I'm connecting is from SAP RAC Service.
Here in our company we have only SAP Logon and my RFC Application, and I can connect to SAP remote system via SAP Logon with this settings:
System Connection Parameters

Application Server: cpe1601

Hi K Patil,
Acording to me you are faceing this issue because the entry of your backend System is not in the SLD (System Landscape Directory ) of your server.
