Tom Help needed again!!!!!!!!JMS Failure Applet

Hi Tom,
          In my application applet is basically the client and it basically does the following
          1)Creates an initial context with the provider url
          2)Looks up for the Topic connection factory
          3)Then using the TopicConnection Factory creates the Topic
          Now the problem is in some of the PC's it gives the following error. at the first step while creating the initial context,pls note that the provider url is correct and we use http protocol with http tunneling enabled.
          javax.naming.NamingException: Couldn't connect to any host [Root exception is org.omg.CORBA.COMM_FAILURE:   vmcid: SUN minor code: 201 completed: No]

          When i placed a .java.policy file with grant {
          permission java.security.AllPermission;
          }; in the c:\documents.settings\<username> folder.After doing this it seems to work in some of machines where the above mentioned error is
          occurring.Pls note that my applet is a signed one, and the network does not have any firewall
          My query is do we have to place this .java.policy file in every client machine and why is that it is not working in all the machine where the above mentioned error is coming.
          Pls help me in solving this problem.
          Pls also note that we have admin rights also on all these machines.

I don't know the answer. The best I can think of is to read the JMS applet white-paper if you haven't already:

Tom Help needed in JMS Clustering!!!!!!!!!

Hi Tom,
          I have a typical problem with JMS Clustering,i amtrying to implement an automatic failover by registering the connection and the session with the exception listener and then inside onexception method i have reconnect logic.
          My application has an applet and the downloading page directly loads the MyApplet jar and weblogic thin client jars and then when i switch of the server using in CTRl-C in windows environment with a single server onException gets fired.Now for clustering we have moved to enterprise archive setup(.ear) and my applet jar and thinclient jars are bundled with in the war(web archive) and the war is inside the ear.In this scenario when i shut down one of the managed servers the onexception does not get invoked and then i shut down both the servers then also its not getting invoked, plz help me i dont understand what is wrong with this,when the servers are on onMessage works fine and my real time blotters also get updated.
          My clustering set up has 2 managed servers,2 JMS servers targeted to each managed server and a distributed topic.
          In a noraml scenario when the servers are running my onMessage gets called, but when i shutdown the servers the onException does not get called from the EAR.
          Pls help me on how to proceed.i cant put the thick weblogic.jar as down loading from my applet cannot handle it.
          Regards,
          Suresh

Sorry Suresh -
          I don't know what is going wrong - my suspicion is that you've found a bug in WebLogic thin-client IIOP.
          Since the problem started when you moved to SP5, you can try continuing to use the SP4 jar on the client.
          And sometimes this type of problem is with with Sun JDK libraries (which supplies most of the thin client IIOP stack), so there's a small chance switching to a 1.5JVM for the client would work (I don't know if BEA supports this).
          You might also try posting to the rmi-iiop newsgroup. (Andy just loves it when I push problems off to him! Well maybe not.)

Design help needed, again

I'm developing a database app, which consists of several applets. Some of this applets are only able to show data, and some others are able to both show and modify data.
Now I need to write a new applet to manage the security of the whole app. This applet will allow the users to log in (with their username and password) and, once the login is validated, it will enable the rest of the applets. If this security applet is ever closed, all the other applets should stop working.
Any ideas on how to implement this ?
Thanks !

You can use the applet context class to deal with
inter-applet communication (google for that, you
should find something). But, I would maybe go toward
a JSP/Servlet based solution for this and let your
container take care of the security bit, plus it gives
you a session to keep the login token info in. You
could still use applets if you need the rich UI, but
stick them in a JSP and lean on the session and
request objects to hold your login token data.
That was completely off the top of my head, so I hope
a) it's accurate and b) it's helpful
Good luck
LeeThanks for your reply Lee.
I think that the method you sugest is something like the sessions under PHP, which I'm sure will solve my problem.
The thing is, my project consists of creating some applets that will enable other people to create customized database management apps. They would only need to create a web page and insert the applet that shows this thing, the applet that does that other thing, etc, etc. But in order for all the applets to work, the developer will insert the applet that validates the user login and unlocks the rest of the applets (maybe, for example, providing them with a database connection).
With this approach, the developer does not need to know how to pogram JSP, PHP, ASP,etc. He/she only needs to insert the applets on a web page and that's it.
That's why I want to do the job using an applet.

Tom !!! Help needed in JMS Topic Lookup Cluster DOMAIN

Hi Tom,
          We have a clustered domain with 2 managed servers and our application is an Applet-Servlet based application.We user JMS Topic for some of online blotters.
          And on looking up we get the following error,
          weblogic.jms.common.JMSException: <055053> <java.rmi.RemoteException: CORBA INTERNAL 1398079712 Maybe; nested exception is: org.omg.CORBA.INTERNAL: vmcid: SUN minor code: 224 completed: Maybe >

          Pls note while looking up for the Initial context since it is a cluster environment, we look up using comma separated Ipaddresses.
          Pls note, we use JRE 1.4.2_13 for the applet to launch,.
          Earlier also for JMS failover i sought your help and your suggestions have really invaluable.
          Request you to provide me some more suggestions on this issue as well.
          Regards
          Suresh

The exception is thrown by the JVM's built in Sun IIOP (CORBA) libraries. I don't know the cause, but a google search for "SUN minor code: 224 completed: Maybe" yields a single hit that might help.

Help needed on JMS queues

I am using Soa Suite 10.1.35 and trying to make a ESB integration work.
The requirement is I have to de-queue some data from a JMS queue and invoke a Oracle Pl/SQL Api(DB adapter) using the data in an ESB project.
I want it part of a single transaction, i.e. if the call to oracle API(db adapter ) fails( say db is down or api is invalid), i want the queue de-queue transaction to be rolled back as well.
I have made the routing service as synchronous. I have marked istransacted ="true" connection factory in oc4j-ra.xml file and auto_commit =>false for the Queue table, queue creation.
Still if the DB transaction fails the queue is not rolled back.
Any help or pointers will be greatly appreciated.
Please let me know if you require any information.

Punit

I tried compling servlet, but it is raising error
that coul not find package javax.servletWhat I did not mention... you need to add those JARs in the Classpath explicitly. You will find them in %TOMCAT_HOME%\common\lib. You atleast need to add servlet-api.jar to your Classpath. :)

Help Needed in JMS Provider

Hi,
In a document for JMS Connector it is given as we need to register the JMSConnectionFactory using Non-JNDI Provider, if our JMS Provider does not provide a naming system.
Does WebSphere MQ(non JMS) provides a naming system? If not should i register it using Non-JNDI procedure? When i register, its asking me to fill the Object Factory class and JMS Factory class? I am not able to find out the class implementing the javax.jms.QueueConnectionFactory and javax.naming.spi.objectFactory interface.
Please help me out.
Regards
Rahul

Javascript Help Needed Again

Hi there, I am not very good with Javascript, so was looking
for some help.
I have a select list for an order checkout page, which is
basically how
people heard about the site. You select one, and depending on
what it
is, another form field will appear with a message asking for
more detail.
For instance, if they selected Search Engine, another field
would appear
with the text "Which search engine" and a form field for them
to enter
it into.
What is the best way to do this? Some of the options in the
select list
won't need the additional field.
Cheers,
Steve

Help needed reinitializing jms

Hi,
I have an application using a JMSTopic and a few JMS temporary queues (weblogic). If the weblogic server goes offline I get a JMSException and I then try to close my connections (topic and queue) and then reinitialize all the JMS objects. After doing that I am able to receive mesages from the Topic but when I try to send to a temporary queue (created after weblogic was restarted) I get:
weblogic.jms.common.JMSException: using closed dispatcher
at weblogic.jms.client.JMSProducer.sendInternal(JMSProducer.java:366)
at weblogic.jms.client.JMSProducer.send(JMSProducer.java:186)
I am sure I close the old connection and I start a new one and create new Session end Sender so I cannot understand what the problem could be, any help?
Thanks,
A.

Try to use delete() to release associated resources.
see http://edocs.bea.com/wls/docs81/jms/implement.html#1135666
here is an extract.
Deleting a Temporary Destination
When you finish using a temporary destination, you can delete it (to release associated resources) using the following TemporaryQueue or TemporaryTopic method:
public void delete() throws JMSException

I need help in establishing a smale applet

Pleaze i need help in creating this small program. any one can help me pleaze.
All what is required is to write a java applet, that does the following:
1) Creates an empty file on the client side. The name of the file is given
by the client user.
2) Reads a file (example: c:\tmp\toto.txt) from the client side. The name
of the file is given by the client user. If the file does not exist, the
applet should display a message error �File does not exist�.
pleaze help me in thaaaaaat :(

Applets cannot access client files by default: In order to do either of these you will need to sign your applet. Google for applet signing and see what you find.

JMS Configuration Help Needed for Publish Subscribe Messaging

Hi,
I am new to JMS and need help to configure JMS from the sun admin console. As of now i have configured the topic and the connection factory from the JMS Resources under the Resources tab(here too i just specified the topic name and guest and password and jndi and similarly the connection factory name but have not specified any port or anything else), but i guess something is missing as i can publish but cannot subscribe nor can i view the messages on the topic..I think some sort of configuration is also need on the Java Message Service header under the Configuration tab.I have searched for this on the net but have not been able to find any sort of detailed help.If someone could give a detailed picture as too how to go about this configuration with an example it would be of great help.

Inter Applet Communication across frames - Help Needed

I am trying inter applet communication across frames. For this to happen I am using an intermidiate
class which registers two applets and whenever any applet needs reference of other applet it gets it
through this class.
The page is an important part of a navigation link. So it is loaded many times while traversing through
the site.
Every time I load this page the applet does not paint itself (shows grey or background) and the browser
stops responding. The machine needs to be restarted. This also happens when we keep that page idle for
a long time (say 2 hours - session does not time out but applet hangs). I have used another thread object
which is for utility and accesses the applet in the other frame every 10 seconds or so.
When the applet hangs it does ot throw any exception or JVM error. This happens on certain machines
evrytime and never on some machines. The applet hangs only in Microsoft IE 5 & 5.5 and never in Netscape
4.x.
What could be the problem?
Can anyone help me with this problem? Its a deadline project and I can't get through.
Thanks & Regards,
Rahul

Try making the register and getter methods of the intermediate class static synchronized. Then register the applets in their start() methods and unregister them in their stop() methods. Call the getter method of the intermediate class wherever you need access to another applet and never cache the instance you get. You may have to also synchronize all your start() and stop() methods to the intermediate class, as well as all methods that perform interapplet communication.
Tell me what happenned ...

Help needed! Raid degraded again!

Hi!
Help needed! I hava made bootable RAID with two S-ATAII 250Gb HDD and its not working! Every now and then at bootup I get a message RAID -> DEGRADED... Must be seventh time! Rebuild takes its own time!
What am I doing wrong!
T: Ekku
K8N Neo4 Ultra
AMD 64 4200+
2 Gb RAM
2 x 250 Gb HDD (Maxtor)
nVidia RAID (in mb)
P.S. I wery SORRY with my poor language!

I'm going to blame the nVRAID because I've seen issues with it in the past. If your motherboard has another non-nVidia RAID solution, use that instead. Using the nVidia SATA ports as BASE or JBOD is fine and dandy but RAIDing always had issues. It's not even a driver issue I think it's just instability. Latest drivers and even boxed drivers never helped. Granted, some will report success with their rig. But on a professional level I've seen nForce issues on different motherboards and different hard drives that had RAID disaster stories.
Good luck and if you don't have another RAID solution, my suggestion would be to buy a dedicated RAID controller card.

URGENT HELP NEEDED ... Tomcat Realm and JRE1.4 plug-in problem

I have tried the Security Realm of Tomcat. Since I do not have
an LDAP server, I decided to use the Tomcat-users.xml file in
Tomcat\conf directory.
I added the following lines of code in the web.xml file.
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>

<role-name>webviewer</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Tomcat Manager Application</realm-name>
</login-config>
The <role-name> "webviewer" is added into "Tomcat-Users.xml" as the following:
<tomcat-users>
<user name="test" password="password" roles="webviewer" />
</tomcat-users>
So, now when we type the url: http://localhost:8080/adbpdbre/default.htm, TOMCAT shows a dialog box asking for UserName: and Password:Now, only when we give the username and password, it shows the page. This is exactly what we want.
But the problem now is, this default.htm page, has 5 links to 5 applets. The first time that I click on one of these links, the JRE plug of 1.4 shows a dialog again asking for the username and password. Till I dont provide the username and password the system doesnt go ahead and applet doesnt load. I do not want the JRE to ask me for the username/passwords again..How to avoid this ?
Can you give me some more information on this. Ultimately in the production usage, we will be using LDAP and not Tomcat's memory realm.
URGENT HELP NEEDED ... I need to get back to my client on this.
Help would be v. much appreciated.

In the config file, you 're essentially saying that you want Tomcat to prompt for usr/passw on every request (url-pattern = /*) made by a 'webviewer', and that's exactly what Tomcat is doing.
Consider using specific url-patterns & roles for resources to be protected. If for now, all you need is to protect the first page, use a more specific url-pattern.
Just an advice : if you'll be using LDAP in production, do not waste time with Tomcat's Security Realm and the BASIC authentication type, since the two have not much in common. Start reading doc on LDAP, and code a prototype, or even better, a vertical slice of the app (i.e a proof of concept).

Help needed with Vista 64 Ultimate

"Help needed with Vista 64 UltimateI I need some help in getting XFI Dolby digital to work
Okay so i went out and I bought a yamaha 630BL reciever, a digital coaxial s/pdif, and a 3.5mm phono plug to fit perfectly to my XFI Extreme Music
-The audio plays fine and reports as a PCM stream when I play it normally, but I can't get dolby digital or DTS to enable for some reason eventhough I bought the DDL & DTS Connect Pack for $4.72
When I click dolby digital li've in DDL it jumps back up to off and has this [The operation was unsuccessful. Please try again or reinstall the application].
Message Edited by Fuzion64 on 03-06-2009 05:33 AMS/PDIF I/O was enabled under speakers in control panel/sound, but S/PDIF Out function was totally disabled
once I set this to enabled Dolby and DTS went acti've.
I also have a question on 5. and Vista 64
-When I game I normally use headphones in game mode or 2. with my headphones, the reason for this is if I set it on 5. I get sounds coming out of all of the wrong channels.
Now when I watch movies or listen to music I switch to 5. sound in entertainment mode, but to make this work properly I have to open CMSS-3D. I then change it from xpand to stereo and put the slider at even center for 50%. If I use the default xpand mode the audio is way off coming out of all of the wrong channels.
How do I make 5. render properly on vista

We ended up getting iTunes cleanly uninstalled and were able to re-install without issue. All is now mostly well.
