My simple bean will not work! Help!
I created a java bean based on a tutorial. After a little bit of trouble with the classpath, getting files in the right place, etc, I finally got it working. Whoo hoo!
Now, I'm working on a second java bean and I cannot get it to work. I'm at the point where I've stripped it down so it's basically identical to the tuturial with just a few changes. When it runs I get a NoSuchMethodError. I've checked, rechecked and re-rechecked my case and my names many many many times. I've rebooted. I've restarted Tomcat and my browser multiple times. What am I missing?
This is my Test.html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
<title>EME</title>

<body>
<form method=post action="Test.jsp">

<td><input type=submit value=Search></td></tr></table>
HHNum: <input type=text name=hhnum size=20><br>

return username;

return age;
}The UserData.class file is in C:\apache-tomcat-6.0.10\webapps\EME\WEB-INF\classes\user
The WebPageData.class file is in C:\apache-tomcat-6.0.10\webapps\EME\WEB-INF\classes\com\penntraffic\emeApp
Both paths are included in my CLASSPATH environment variable.

If I remove the line that attempts to get the value of hhnum from the bean, everything works fine and I get the username value from the first bean. So the user bean is working, but there's obviously something wrong with my second bean (webPageData).
I've also tried using <jsp:getProperty name="webPageData" property="hhnum"/> rather than <%= webPageData.getHhnum() %>. I thought they would return identical results, but instead I get the below errors:

Tried to copy/paste from an article to my web site and got a "cannot copy /paste " warning and was directed to a security perferences site that said that Mozilla Rich Text Editing demo page will not work.
Tried to find my Firefox profile directory using the start menu and was directed to hit enter to go to web. Feel like i am getting run around.Let's start with something very basic, and that is, you do not need to use the paste button on most websites. The button just reads what is on your clipboard and sticks it into the form. You can do that yourself using Ctrl+v or right-click>Paste.
For your security, I suggest using those standard Windows keyboard shortcuts (Ctrl+x cut, Ctrl+c copy, Ctrl+v paste) or the context menu.
Occasionally you will find a paste button that runs a clean-up script or otherwise does something useful. That is where the (admittedly a bit complicated) instructions come in handy.
To open your active profile folder, you can use:
Help > Troubleshooting Information > "Show Folder" button
Which help article are you using for the modifications?
Finally, please be cautious in opening up your clipboard to sites. You may have stuff you copied from other pages or other programs that you do not want to share with most sites. -

OMG, after last AIR update before current ALL my AIR apps will not work, HELP!
I have 5 or 6 AIR based apps after I did an update last month, none of them will work. I just re-installed and updated AIR again today and re-installed all the apps multiple times and when I go to one it trys to open the last I installed for every app it only opens the last installed. App installions always end with "faled to open app" and in the log I see this "Error: Missing necessary file META-INF/AIR/application.xml" not sure?
Windows 7 (all lastest updates)
Latest Air (13.057 I believe?)
How do I fix this, why did it break?
Full log:
http://ge.tt/2IDeU4b1/v/0?cHello,
I could install and run the AIR application successfully with AIR 4.0, 12.0 and 13.0.
Looking into the log, it seems that "missing application.xml" and "Application Installer end with exit code 7" issues have been there from 2014-02-09, below is the detailed log seen from http://ge.tt/2IDeU4b1/v/0?c. This issue maybe caused by the application.
Is there an application.xml under C:\Program Files (x86)\YourApplicationXXX\META-INF\AIR\ ?
If possible, could a bug against this issue be logged in https://bugbase.adobe.com/, and upload the AIR application which does not work. That would be very helpful to triage and find the root cause for this issue.
Thanks your support!

Can not install windows 7 pro using boot camp as mouse and keyboard will not work Help please
I have a new iMac and trying to install Windows 7 Pro using boot camp. I have reached the stage of starting to load windows from the DVD then discovered the mouse and the keyboards not working so I could not interact with windows installation.
Open, if not so already, the Windows formatter. Identify the BC Windows partition. It will be the one listed with the proper size you created and/or will be labeled as a C: drive. Be careful you select the right one or you may be corrupting the entire drive.
Format the partition as NTFS. -

Simple slideshow, will not work in as 3.0
L.S. I have this little slideshow, it is for practise for my students. It always worked well in as 2.0,
5 slides, and two buttons: back and next.
The script in2.0 has: prevFrame and nextFrame in the code
and for the exceptions in frame 1, and frame 5 we made a new frame 1 in the actions layer, and coded the back button, gotoAndStop(5); and a new frame 5, and coded the next button: gotoAndStop(1);
Works.
Now I put the thing over tot as 3.0: And I can not get it to work properly....the buttons work, but when I am on frame 5, and go back to 4, it will go no further than 4, evenso when I go back to frame 1 from 5, I can not go further up than frame 1.
What do I do wrong??
attached is the fla in cs5.
Thanks,
Anne Vossen
Message was edited by: Vossen I am sorry but I can not find the button to load up my files...so here is the script:
as frame 1:
import flash.events.MouseEvent;
stop();
next_btn.addEventListener(MouseEvent.CLICK, volgendFrame);
//next_btn.addEventListener(MouseEvent.CLICK, eersteFrame);
//back_btn.addEventListener(MouseEvent.CLICK, vorigFrame);
back_btn.addEventListener(MouseEvent.CLICK, laatsteFrame);
function volgendFrame(evt:MouseEvent):void{
nextFrame();
function eersteFrame(evt:MouseEvent):void{
gotoAndStop(1);
function vorigFrame(event:MouseEvent):void{
prevFrame();
function laatsteFrame(event:MouseEvent):void{
gotoAndStop(5);
frame 2:
next_btn.addEventListener(MouseEvent.CLICK, volgendFrame);
//next_btn.addEventListener(MouseEvent.CLICK, eersteFrame);
back_btn.addEventListener(MouseEvent.CLICK, vorigFrame);
//back_btn.addEventListener(MouseEvent.CLICK, laatsteFrame);
frame 5:
stop();
//next_btn.addEventListener(MouseEvent.CLICK, volgendFrame);
next_btn.addEventListener(MouseEvent.CLICK, eersteFrame);
back_btn.addEventListener(MouseEvent.CLICK, vorigFrame);
//back_btn.addEventListener(MouseEvent.CLICK, laatsteFrame);It will be easiest to manage if you just have the buttons coded once for the entire timeline with the special conditions written into the functions instead of switching listeners. And if you use totalFrames instead of the actual number (5), you can add frames in the future without having to change the code... Frame 1...
stop();
next_btn.addEventListener(MouseEvent.CLICK, volgendFrame);
back_btn.addEventListener(MouseEvent.CLICK, vorigFrame);
function volgendFrame(evt:MouseEvent):void{
if(currentFrame < totalFrames){
nextFrame();
} else {
gotoAndStop(1);
function vorigFrame(event:MouseEvent):void{
if(currentFrame > 1){
prevFrame();
} else {
gotoAndStop(totalFrames); -

Reset Settings
What this effectively does is to reset some of your Settings to factory default. It’s not a complete removal of settings. It removes all of your preferences for Wi-Fi, Bluetooth, Do No Disturb, Notifications, General, Sounds, Brightness & Wallpaper and Privacy. It doesn’t affect your data. All of your email accounts will remain intact, as well as any SMS text or iMessages.

My WRT54G2 will Not Work HELP NEEDED !! PLease Help
Hey i Have a WRT54G2 and it has worked Flawlessly for about a Year... One Day i Wake u To No Connection coming From my Linksys ..... on the Wirless Connections Pop up there is a Message saying " Information Sent over this network might be visable to others" I Have Tried Everything and Anything to Figure Out or Fix the Problem But NOthing i Do Works ... I am Really Out of Options ,,,,, Someone PLeaseeeee HElllllp Meeeee !!!!1 Aaaahhhhhhhhhhhhhh
In this case try to change the power socket. Try to do 30/30/30 hard reset. The following procedure will clear out the NVRAM and set Router back to default values:
~~ With the unit powered on, press and hold the reset button on back of unit for 30 seconds
~~ Without releasing the reset button, unplug the unit and hold reset for another 30 seconds
~~ Plug the unit back in STILL holding the reset button a final 30 seconds....
Then make the physical connectivity. Here are the steps for the physical connectivity for the router:
The router’s power adapter needs to be plugged to your router and into an available power outlet.
If using a wired connection, the first Ethernet cable needs to be plugged to the computer’s LAN port into any of the router’s blue numbered Ethernet ports.
The second Ethernet cable should be plugged to the modem’s Internet port and the other end into the router’s yellow Internet port.
Ensure that you have no firewall enabled that may prevent the router from being detected.
Then make the manual settings according to the ISP setup. Here is the link for setting up a Linksys router with Cable Internet service:

Nokia 500 auto navigation will not work
I have a nokia 500 auto navigation and it will not show maps or it start to boot and freezup and will not work Help!
I had the same problem a couple of months after activating the gps.
I think my problem came up after I had loaded some songs and video onto the SD card.
I used the DVD to restore the maps etc. Be careful with that. The software to run the video/music is not included on the restore DVD.
I had to do the restore multiple times. Finally, I found an update on the Nokia website and did the update. DON'T DO THAT = my bluetooth has now stopped working. Bluetooth says it's on and you can turn it off, however, there's no change. It says on, but no devices can connect to the gps anymore.
Frustrated with Nokia? YES. I have had it sent back, but since I bought it on ebay, forget about that. -

at java.lang.Thread.run(Unknown Source)Hi -
Webutil.jar is with older version. Now it goes with frmwebutil.jar.
It is working now, I opened a TAR with Oracle and that was helpful.
From Oracle:
This issue can have various causes.
1) Lack of olb at compile time
The Note 270940.1 Oracle Forms WebUtil : Technical FAQ mentions the following
lead:
Ensure that the FMX was generated with no error messages. E.g. if webutil.olb
is not on FORMS_PATH, the error message could be overlooked even though the FMX
is generated.
2) Lack of jar at runtime
normally using config=webutil allows to have archive=....,frmwebutil.jar,...
so should not be the case here
3. Lack of bean in custom form A custom form should have followed a step such as
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
( as mentioned in step 9 of Note 333385.1 Kickstarting WebUtil 1.06 in
Developer Suite 10.1.2.0.2 on Windows )
4. If the error continues, please download the webutil test form WU_TEST_106.FMB fro
m:
http://www.oracle.com/technology/products/forms/htdocs/webutil/webutil.htm = >
Webutil Demo
or directly from:
http://otn.oracle.com/products/forms/htdocs/webutil/Webutil_demo.zip
5. generate the fmx ( ensuring the webutil.olb and webutil.pll are in the
FORMS_PATH )
6. Make sure that when called WEBUTIL in a new-form-instance-trigger when the bean is registered, otherwise, this error will
arise.
From Me:
1. Form compiled correctly with no errors. However, FORMS90_PATH is not set with
webutil.olb and webutil.pll. So I went added in FORMS90_PATH.
2. Don't see any issues with config=webutil, archive=frmwebutil.jar, jacob.jar
3. I did subclass the pll. Don't see any issues.
4. I recompiled and tested, still gets the same error.
5. I went downloaded the demo form WU_TEST_106.FMB
6. I compiled and reran the form, got an error saying no attached libraries found.
So I went and renamed webutil.pll to webutil_lib.pll. Reattached to the
forms.
7. No I get an different error.
Oracle.forms.webutil.clientinfo.GetClientInfo bean not found.
WEBUTIL.CLIENTINFO.GET_SYSTEM_PROPERTY will not work
This was resolved my changing the URL to
http://Host:8890/forms90/f90servlet?form=WU_TEST_106&config=webutil
Thanks for your support.
Thank You,

Please help! Itunes fails to open on my macbook pro. I have removed itunes and reinstalled it and it still will not work!
Try removing the Genius database. In the "Finder" go to the /username/Music/iTunes/ folder and delete the "iTunes Library Genius.itdb" file. This may allow the program to launch again. This file will be recreated upon first use of the "Genius" feature.
