Unable to run Web App for the 2nd Time

Hi,
I am using Weblogic 8.1 sp5 as my deploying platform. Using the official tutorials, I am able to export my JSC2 web app into a WAR file that is deployable on my Weblogic server.
Upon running the application, it works perfectly. However, upon closing my browser and then restarting the browser, running the web app again yields exceptions, please refer to the bottom.
What am I doing wrong? I am suspecting the web-app wasn't detroyed properly when another instances of it is started...
Please advise.
Adams

Well, I have solve this problem myself.. apparently, I used static variables to initalise the app. Changing the static variables to session variables solved the problems.

Scoping out Sharepoint - Is it possible to run web apps in the same domain as a web page? (ie not with references to a cloud)

From what I understand, with sharepoint it is possible to run web apps on the server that don't need to be referenced via the cloud, ie in contrast to SkyDrive.
If so, would it be possible to create a web site on the share point server that embeds say a word web app in a page, all done in the one server, on the same domain?
Thanks

Hi,
First Office Web Apps and SharePoint can't be installed in one server as it's not supported. So you need at least two servers - one for SharePoint and another for Office Web Apps. About 'word web app', As far as I know you can run word app/excel app runs
in either word/excel but not inside Office Web Apps.
Thanks,

Running app for the first time NOT

Suddenly I get this message for some of my Applescript apps I have been using for years,
"You are opening the application “name.app” for the first time. Are you sure you want to open this application?"
Even after saying yes and running it the message persists every time. I have verified using the terminal that the quarantine flag is not set for the app.
Any thoughts on this? Better, any solutions?

Check your Gatekeeper settings.

My macbook pro retina 2014 has crashed for the 2nd time in 2 mo

My macbook pro retina 2014 has crashed for the 2nd time in 2 months. Can't get past the gray/apple screen. The first time the genius bar tried all the different tricks to get it to boot all the way through, but in the end had to reinstall mavericks. They said there weren't any indications of it being a hardware issue after running diagnostics. The only possible reason is that it has something to do with some ProTools 10 plugins which I had downloaded in both occasions less than a week before. I don't believe that would be the issue and I'm guessing it's a hardware issue at this point. It's still under a factory warranty, so I'm not too concerned. Thoughts?

Try SMC and PRAM resets:

When Webdynpro popup is opened for the 2nd time, image is not shown

Hi Experts,
We have created a WebDynpro with a popup window.
This is shown in an iView in the portal.
If the popup is opened for the first time it looks good.
If the popup is opened for the 2nd time the image is not shown and the title is shown with a different font.
If we do a preview of the iView in PCD content area, the title and image is shown and the right font is used: also when you open this for the second time.
If the iView is in a role the problem appears.
How can this be solved?
Thanks in advance,
Joeri

Sounds like a wrong reference to a stylesheet.
Use IE Developer Toolbar or Firefox to debug the code. Or view source (of the popup) and search for .css. Do the same for the popup that doesn't work. Check if there are differences.
Good luck!
Noel

You may have no need for additional but Apple does. They don't want your iTunes account to be hacked and then go complaining to them that their security procedures are not up to standards.

Its really absurd to even ask this in light of the information that you have been given already. The "old fashioned" way is gone. It's Apple's store, Apples's rules and IMO - its a wise decision on Apple's part.
You do not have to comply at all, but you will not be able to purchase from iTunes anymore, but nobody is going to force you to do something that you do not want to do.

Unable to depoly Web Serivce for the source code written in other editors

Hi all,
I am planning to implement webservice with the following code. But I am facing few problems with this can some body help me with this.
The code looks like this AND IS NOT WRITTEN IN Jdeveloper BUT EDITPLUS
package package1;
public class Sum
public int getSum(int a, int b)
          return a+b;
package package2;
public class Sub
public int getSub(int a, int b)
          return a-b;
package package3;
import package1.*;
import package2.*;
public class Mul implements TestInterface
     Sum sm = new Sum();
     Sub sb = new Sub();
public int getMul(int a, int b)
          return sm.getSum(a,b)*sb.getSub(a,b);
public static void main(String [] args)
          Mul ml = new Mul();
          System.out.println(âThe result of (3+6)*(3-6) is â+ ml.getMul(3,6));
package package3;
interface TestInterface extends java.rmi.Remote;
     public int getMul(int a, int b) throws java.rmi.RemoteException;
I have written this in editplus. Not in Jdeveloper.
Now I want publish getMul() as web service using Jdeveloper.
I have created a new application work space. And from File-->New
I have choose project from existing source and imported âpackage3â.
At this stage it was unable to find the class files Sum and Sub so I placed Sum.class and Sub.class in Appliction1-Project1-classes-
Now the Mul class did not have any errors and it compiled fine. When run it gave the correct output.
Using the web service wizard I was able to generate wsdl file , deployment descriptors etc.
The problem I was facing was form this stage when I am trying to deploy it on to a standalone oc4j server it is not able generate the WebServices.war file and hence is not deployed on to the server.
With the same code written in Jdeveloper everything is working fine.
My doubts are
1)     why is it not able to generate WebService.war file?
2)     It is giving some ClassNotFound exception during the deployment. But when compiled and run its giving the correct output.
3)     Even when everything was written from within the Jdevelper it did not include Sum.calss and Sub.class in WebSevice.war. Is there any way we could mention during its (WebService.war) generation , the class files to be Included.
The other issue is how to add an existing source code to already existing project. In my case Once I have imported package3 I also want to import package2 and package1 in different steps.
I thank in advance for helping me.

Can you tell us what you mean by correct type of project?
You can start with an empty project. Then, you have to create an "EAR file" deployment profile (New Gallery / General / Deployment Profiles).
So when I deploy a J2SE module onto oc4j server should I specify the class path? If so where ? How can I solve this problem?
Once you deploy your code into oc4j, it becomes a J2EE application. You don't need to deal with the classpath - just make sure that all the required code is included in your .war file. To do so, check the list of classes packaged under the deployement properties dialog.
Can you send me the links of few articles where I can learn more about these kind of stuff?
If you want to assemble applications without to use JDeveloper wizard, you have another option: using the WebServiceAssembler tool that is par of the oc4j bits will help you to do this from a command line promt, and will handle the J2EE packaging aspect for you.
See online documentation (10.1.2): http://download-west.oracle.com/docs/cd/B14099_04/web.htm
In the "Developer's Guide", chapter 9 is about "Web Services Tools"
For JDeveloper J2EE samples, you can start by looking at the OBE: http://www.oracle.com/technology/obe/obe_as_1012/j2ee/index.html
Hope this helps,
Eric

Running JDeveloper 11122 for the 1st time error

Hello there,

Running 2 apps at the same time

My wife has an ipad2 that she loves, but she just updated the ios to 6.1.3 from 6.0, thanks to me, and now she is really upset. She "use" to be able to listen to audio from Youtube on Safari, bad youtube apps, and also be able to play games at the same time. Now with this upgrade, she can't do this, the audio just shuts off when she starts the game. She aleady knows the process of starting the youtube video then doubl clicking the home button to bring up th menu at the bottom of the page and then starting her game, but the new iOS just shuts off what she was listening to. Is there a fix for this or an easy work around?? We don't want to jailbreak either, because we shouldn't have to.
do the newer ipads handle multiple apps running at the same time better with the faster chips??

Hi Tim,
I'm a little confused by this, if you listen to music from the Music app on the iPad this should still keep playing when doing other stuff but anything playing in Safari that I've had playing has always turned off when switching between apps.
Regards,
Steve

"Newbie" Unable to run two actions at the same time please help

Hello
I'm a newbie (2 weeks) on Labview, so I hope my problem will sound easy for some of you.
I want to read a file and at the same time get the reading from my sensors (4 sensors).
My program is working when I do each thing in a different program but when I add them the program only read the text file and stop reading the sensor signals...I attach the program file.
The goal is with the text file to add an exact time for each sensor signal I record.
Is there any other possibilities to include a time with the sensors signals recorded ? I need to do this to synchronize the sensors values with CAM program.
Thanks
/Xavier
Ps I used a scan rate of 12000/s but I try 1000/s
and the sensor acquisition is still not working

from a glance at your code, it appears that you have nested a loop to read your file, inside a loop to read your sensors. this means the nested loop to read your file must finish before the outside loop to read your sensors can run through another iteration. what you want to do is separate the two loops to run independently of each other (in parallel). use a global variable to know when to stop the loop (if they need to stop at the same time) and if you need to pass data between the loops use a queue (easiest) or you can also use globals with semaphores.

Help: I want to auto schedule a load using file watcher but it runs only once for the first time and after that it is not running at all

Folder content disappears for the 2nd time

Two weeks ago I noticed that some of my folders in Documents are empty. I thought it might be a problem that refers to the last backup, so I was replaced that empty folders with those from backup disk. But today I have the same problem, this time one folder is empty. Does anybody know what's happen to my mbp?
thanks

I've got a list of things to look at and tryout to see if we can narrow down what's happening. Try any one in any particular order see if the problem keeps happening.
1. What format are the original photos in?
If they are in Jpeg and it's failed each time, are they coming out of iPhoto, Photoshop?
File size may also be a problem if they are very large files.
2. In iMovie, Duplicate the project in the Project Library
Try dragging a photo into that copy of the project
Any differences? If you can import photos into the Duplicate, try copying then pasting into the original and see if the image shows up.
3. In iPhoto Duplicate a picture in the iPhoto Library
If you want to have a particular picture and can find it within iPhoto try making a duplicate.
Does it show up in the Photo browser? And can you drag that duplicated picture into the project? What do you see, what result do you get?
4. Clean the iMovie cache
Quit out of iMovie. Then go to your Movies Folder > iMovie Events > Project folder name
Drag the folder "iMovie Thumbnails" to your trash. Then open the folder "iMovie Cache" and drag the file "Cache.plist" to the trash.
This should regenerate any cached thumbnails for the project, may be helpful.
5. Try tossing out the iMovie preferences
Quit iMovie.
Open a Finder window to your user's Home folder>Library >Preferences folder. Find the file named "com.apple.iMovie.plist" or "com.apple.iMovieAppl.plist" and move it to the trash.
Try opening iMovie again, then opening the project and dragging a photo from the Photo Browser into the Project timeline.

Blackberry 8330 keyboard doesn't work for the 2nd time

Hi, this is the second time that this has happened to me. The first time, I had finished a text message, and left it on my bed, only to come back an hour later, and the entire keyboard didn't work. The only thing that worked was the trackball, but it could only move around; I wasn't able to click it or anything. After many battery pulls, I looked online, and saw that I could try to reload the OS using application loader. I did that, but I was left with the same error. I eventually ended up having to go to the store, and as I was still under warranty, got them to replace it for me. All in all, a huge hassle. Lo and behold, two months later, the same issue is back. I've tried the battery pulls, and reloading the OS, but nothing seems to work! Any ideas? I don't want to have to keep going back to the store to replace it.

I have the same problem on My Blackberry 8310 Curve..

Unable to run Web App for the 2nd Time
