Problem modifying the connection details in a Report when using Weblogic 12
Hi
I have a j2ee application that uses the Java Reporting Component (JRC). At runtime, the code programmatically changes the connection type and schema name of a crystal report before running it. The connection that was used when designing the report is replaced with new JNDI parameters pointing to a Weblogic/Oracle datasource.
The application works perfectly when using Weblogic 11, but the same code and report fails when deployed to Weblogic 12.
I used Version 12.2.207.916 of the JRC, and updating to the most current version I could find (12.2.217) did not solve the problem.
The code snippet below shows how the connection and schema name is replaced for each of the tables in the report (not all the code is shown here)...
PropertyBag propertyBag = new PropertyBag();
propertyBag.put("Database DLL", "crdb_jdbc.dll");
propertyBag.put("JNDI Datasource Name", jndiName);
propertyBag.put("Initial Context", "");
while (tableList.hasNext()) {
ITable table = tableList.next();
ITable tableNew = (ITable) table.clone(true);
IConnectionInfo connectionInfo = table.getConnectionInfo();
connectionInfo.setAttributes(propertyBag);
connectionInfo.setKind(ConnectionInfoKind.SQL);
tableNew.setQualifiedName(newQualifier + "." + table.getName());
tableNew.setConnectionInfo(connectionInfo);
dbController.setTableLocation(table, tableNew);
The setTableLocation() function throws the following exception ...

Any idea what I can do to fix this ?
Thanks in advance!
Last reference in any documentation re. version of supported weblogic is 10.3.x. And it may very well be that things worked in weblogic 11, but as versions go by the differences get bigger and eventually the app stops working.
I'll ping the Program Manager for definitive info and future support. Once I have the info, I'll update this Discussion.

Problems with the ActiveX bridge for Java beans when using third-party .jar
I encountered the following problem when using the ActiveX bridge for a java bean:
I am using JDK 1.4.2_09 and MS Visual Basic 6.0 (SP6). I wrote a java bean called ProcessViewer (my class ProcessViewer inherits from JComponent and implements the interfaces Serializable and AdjustmentListener) which I would like to use within a VB 6.0 application. I used the ActiveX bridge (packager.exe) to generate a DLL (ProcessViewer.dll) and registered it successfully. The java bean GUI-control works fine within my VB 6.0 application unless my java bean (ProcessViewer.jar) uses any third-party .jar files.
But when I tried to add a reference to some third-party class (com.sap.xxx.xxx....) I got some problems. I could solve the problem with packager.exe by setting the correct CLASSPATH. But at runtime my VB 6.0 application does not work. It crashes or it reports an error like this: "The control ... could not be loaded from axbridge.dll" (although I deployed my .jar file correctly to the directory C:\Programme\Java\j2re1.4.2_09\axbridge\bin and lib). Setting the CLASSPATH environment variable before calling my VB 6.0 application (exe) did not solve the problem.
How can I teach my VB 6.0 application (containing the Java bean ActiveX control) where to find the third-party .jar file? Copying the third-party .jar file to the JRE lib-folder or to the axbridge\lib folder did not solve the problem either.
I studied the documentation about the ActiveX bridge given at:
http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/index.html
but I am missing informations on how the third-party .jar files can be found during runtime of the ActiveX container (e. g. a VB 6.0 application).See how to solve your problem with JNI:

hi, my iphone is not connecting to wifi. there is no problem with the connection of wifi. i tried so much but the connection is not stable. some times it connect and sometimes not connecting at all. if connected also its disconnecting again.pls help
At the very least, I recommend you restart your router, (your internet box).
More detail on your problem is needed - are you in a submarine? On the moon? On a tropical island?
You can help yourself by providing as much info as you can about your present situation - what kind of router do you have? Have you moved it? DId you update it? Did you do anything to change your setup, and if you did, what? -

I have an airport extreme and express setup. My extreme is in my 2nd floor office with windows facing the water. My dock is about 250 ft away down a very steep hill. I have the express about 100 ft down the hill in an electrical waterproof box attached to a tree as high as I could install. The signal is weak and I'm thinking I might have to buy another express. Any thoughts on the best setup for me. I ultimately want to control speakers(hard wired in) down at the dock with my iphone. I have a receiver coming with airplay built in.
Thank you all for the responses. By process of elimination, I think the problem is the connection to the express in between the extreme and dock. I bought another express and tried it at dock, no luck, I then replaced new express where the one is between extreme and dock, no better. I unplugged the express between extreme and dock and there was no difference. So I believe I am connecting to the airport express or extreme that is inside the house. Again because when i approach express that is halfway I reconnect. so if you can understand my chaos, I believe the express in between is not really connecting to the extreme inside my house. Yes, No? So I need to know how to know if the express half way down the hill is getting the connection from the the extreme in the house. This is wearing me out!!!!!You are asking several different questions. If you need to store your photos, music, and movies on an external volume, you certainly can. Any externally connected hard disk drive will work, connected either directly to your Mac or to your Time Capsule as a shared volume.
You should not rely upon using that as a backup device though. Although you certainly may use it for both purposes, it is a better idea to have dedicated backup devices for a variety of reasons not limited to redundancy. You would not want to simultaneously lose all your pictures as well as your backup. If they are all on the same device, that could happen. Furthermore, a backup cannot back up the volume on which it is running.
As for adding an Extreme or Express, using its LAN port for your iMac, and then enable Internet sharing so you can effectively use the iMac as a "hotspot", you can do that too, but I am unclear on what benefit you believe this arrangement would convey for you.
An Extreme's Guest network is separate from its Main network; that is the reason for having it. -
Hi,
I recently got myself an apple iphone 5s (factory unlocked) phone from the US. However on using the same in India with Vodafone, i am facing a problem where the connectivity keeps switching to EDGE most of the time. I have a 3G plan but most of the time it switches automatically to EDGE. Thats when i have to either switch Airplane mode - On/Off and then it acts normal. Any permanant solutions to fix this problem?Return the iPhone personally or via friend/relative/co-worker who is in
the US. The warranty is valid only in the country of original purchase - the USA
in this case. Apple will not accept international shipments for evaluation nor
will Apple ship out of the country after repair/replacement.
How did the iPhone from the US get to you in India? Reverse that process to
get it back to the US so someone can take it into Apple. -
I have a problem with the external sound of my iPod, when I take the headphones the music keeps playing and the ipod recognizes still have a headset connected. how do I get external sound out?
- Try insering and removing the headphone plug a dozen times or so.
- Try cleaning out the headphone jack in the iPod.
- Resett he iPod. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restoe to factory defaults/new iPod
If yu still have the problem that indicates a hardware problem, likely a bad headphone jack. Yu can make an appointment at the Genius Bar of an Apple store to confirm.
If not underwarranty Apple will only exchange your iPod for a refurbished one for:

Phani Kumar RSorry Tom, I dont like to hear "There is no way" :-(
There is always a way in computer to get what you need (at least it is good as Rule of thumb). I am not sure we will find it here (in a voluntary supporting forum).
Now we (or better the architect of their system) should think of the way :-)
Of course doing so in the forum, while we do know the system and only got a glimpse on what is needed, is not the best idea. I will point some issues which can be related to a solution. Those are not a solotions as it is but something we can use for a solution
once something look in the right way.
* A web connects counter is one of the easier thing to do. The basic idea is just to use the connect event and the disconnect event an adding 1 or removing 1 from the counter. This is best to do in the application using static variable as any way the second
the application is down the counter can be go to hell as we know there is no one connect (there for a counter do not use database usually). Using a web dot-net (or asp 3) application this is done most of the time using the global.asa/global.asax file, which
include the application and session events. for example using the method Session_Start
protected void Session_Start(object sender, EventArgs e) {
// Code that runs when a new session is started
* IIS have a build-in loging system where we can log each and every request/response or only logins users. There is lot we can do with this log files including data mining. Using small bulk insert script we can use the SQL agent to insert those logs to the
database and get the information we need.
* any web developer i want to believe know about the Fiddler application which we use to monitor traffic. A proxy is not the only way to to monitor traffic (it is not good for our case as this is in the client side), there are several option in the server
side.
* SQL trigger on logon can be use to get information on who is loging on and can be logging only specific source (like our sharepoint IP or any sharepoint application). This information (what is the application which connect to the server can be retrive
in several solution without using a trigger as well)
*** (I'll be brief ... I'm getting bored... probably the reader feel the same)
* using extended events and/or profiler we can monitor any connection and save the data or just remember it in shared (static) variable (this
blog show how to do it by the way). Again we can monitor specific application or use any filter in order to get only the sharepoint users
.... and i can continue for several days more :-) ...

many of the apps in my newstand won't let me get past the "connect to iTunes" notification. When i touch "OK" the same notice keeps coming back. What do i do.
Settings>Store>Your Apple ID - tap the ID and then sign out.
I only have one app in the Newsstand folder - the Sports Illustrated app. I have never gotten this message about connecting to iTunes so I'm not sure what that is all about. I would quit the Newsstand app and the other apps and the restart the iPad and see of that helps.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesnt work, reset the iPad. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. -
How to Modify the Header/Footer that's created when printing to PDF?
Hi all,
How do I modify the header/footer that is added when I use the Adobe PDF printer in another application, like MS Word? Currently it adds the entire path of the file as the header, which is really annoying.
I'm not talking about the Header/Footer command in Acrobat's "Document" menu. In fact, that command doesn't even recognise the header that's generated by the Adobe PDF printer.
I'm using Acrobat Pro 8.1.3, btw.
Thanks :)Generally you should set the whole look of the page in your application and then print to the Adobe PDF printer as you have been doing. If you are using a browser, there are header and footer commands for the printer that are typically set by the browser - those can be modified there. The PDF should look just like the preview in the application, that is the point of a PDF.
