Subject: Program compiles, but does not run
I am trying to port a Java application from the PC to the Mac. I am using XCode and the program compiles, but it does not run.
When I try to run the ...app, I get the message that the main class is not specified, etc.
When I try to run the ...jar, I do not get the message that the main class is not specified, but I do get the message that there is no Manifest section for bouncycastle, etc.
Here are the detailed messages I get in the Console when I try to run the program:
When I try to run the ...app, I get the following message:

I do specify the main class in both, the Manifest file and the Info.plist file, in the correct way, "package.MainClass". Is there another place where I need to specify it?
Why do I need org/bouncycastle/asn1/DEREnumerated.class, and how would I have to specify it in Manifest?
I also posted these questions at Mac Programming at forums.macrumors.com and at Xcode-users Mailing List at lists.apple.com/mailman/listinfo, but I did not get any answer.
Please help! Thanks!
There was something wrong with my Info.plist file.
So, here is my corrected Info.plist file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</plist>Ok, so now I can at least run the AnanyaCurves.jar file by double-clicking on it.
However, I still cannot run the AnanyaCurves.app file. When I double-click on it, I get the following message in the Console:

Isn't this outdated? Shouldn't it look for the Info.plist file? I do not have a MRJApp.properties file.
Also, in the Run menu of my XCode project, Go, Run, and Debug are disabled, but perhaps this has to do with not being able to run the AnanyaCurves.app file.
Thanks for your time! I really appreciate any help you can give me!

An applet is a special kind of panel so you can just change "p" to "this" everywhere in init and remove the declaration of p at the top.

My adobe captivate6 installs but does not run on my windows7 dell inspiron
my adobe captivate6 installs but does not run on my windows7 dell inspiron with 4gb ram and 500gb hdsk, i downloaded the trial first 32bit and it installed fine and didnt run. so i thought that a full version with a 64bit installation will do the trick, but after that the captivate 6 did not still work on my system. i also tried it on an acer with duo core and the captivate software installed and did not still work. it only shows the captivate flash screen.
a friend installed his on an acer laptop 64bit, i3processor, and it works fine. please i will be glad if i can be helped on how to correct this
thanksHave you tried right clicking on the Cp icon and selecting Run as Administrator? This is something you MUST do in Win7 but was not necessary on Xp.

This program is well compiled but does not work.
I would like to know why this program does not work properly:
the idea is :
1. the user introduces a text as a string
2.the progam creates a file (with a FileOutputStream)
3. then this file is encripted according to DES (using JCE, cipheroutputStream)
4.the new filw is an encripte file, whose content is introduced in a string (with a FileInputStream)
(gives no probles of compilation!!)
(don know why it does not work)

As sudha_mp implied, an unsigned applet will fail on the line

due to security restrictions. (Which, incidentally, are there for a very good reason) -
Project Runs With No Errors Compiled in VS2010 - Compiles But Will Not Run with VS2012 or VS2013.
I am trying to do all of my work in Visual Studio 2013, but I have found that, in one case (at least), if I compile the project in VS 2013 or VS 2012, I get the error "Could
not load file or assembly 'NationalInstruments.DAQmx, Version=9.4.40.50, Culture=neutral, PublicKeyToken=dc6ad606294fc298'
or one of its dependencies. The system cannot find the file specified."
Yes, I am loading a third party DLL and here's what is strange... If I compile it with VS2010, I have no problem - the program works correctly - no errors. If I take the same solution and load it in VS2012 or VS2013, it compiles cleanly and looks good (no
errors and no warnings) - until I run it.
So, how do I get this to work with VS2013? And what changed? And with the number of developers in this company - it HAS to work with VS2010, 2012 and 2013 (different developers have different licenses), so how do I get that and how do I ensure that
future development does not have this problem?
The project targets .NET framework 4.
RobHi,
If the error occurred at a third-party dll, then it is out of support range of forums. Please consult your issue on the forums/communities provided by the third-party dll for better solutions and support.
Moreover VS General Question forum mainly discusses
the usage of Visual Studio IDE such as WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Best regards,
We are trying to better understand customer views on social support experience, so your participation in this interview project would be greatly appreciated if you have time. Thanks for helping make community forums a great place.

Exception in thread "main" java.lang.NoClassDefFoundError: StdInThat means that you are using a class (StdIn), that is not on your classpath, but in some other place.
The "-cp ." tells Java to ignore the CLASSPATH variable and just look in the current directory instead. You probably had the location of StdIn on your CLASSPATH variable.
What you need to do in this case is to add the current directory "." to your CLASSPATH variable.

ITunes installs but does not run on Windows 7 64-bit
I've spent a couple hours going over advice on this forum as well as elsewhere on the Internet to resolve this. iTunes installs without a problem but when we run it, nothing appears. iTunes.exe *32 and iTunesHelper.exe *32 appear in the Windows Task Manager but there is no other evidence that iTunes is running.
I've tried installing and reinstalling. I've tried a number of different compatibility settings. Surely there must be an easy way to resolve this.
Frustrated,
AndyThe problem, as it turns out, is Bonjour. See http://discussions.apple.com/thread.jspa?threadID=2408851&tstart=0 for ideas on how to fix....

Lightroom CC installed but does not run
The CC update has run and I now have Lightroom CC installed .... or so I thought.
I have a new shortcut for LR but it does nothing.
My old LR 5.7.1 still works - if I open this and check for updates it says it is up to date.
The new LR link is "C:\Program Files\Adobe\Adobe Lightroom\lightroom.exe"
After the LR update, CC said it needed updating so I did the update.
It now says I have the following apps installed ...
Photoshop CC Update Ready
Photoshop CC (2014) Update Ready
Bridge CC Update Ready
Lightroom 5 Up to date
Lightroom CC (2015) Up to date
Edge Inspect CC Up to date
I am not aware of any updates for the first 3 items
I presume the multiple copies of versions may be part of the problem.
Any idea how I proceed?It seems to have worked ! I was doubtful since I had already rebooted so I thought that would resolve things.
After the logout/login, I launched LR and updated my default catalogue. Then notified me that a third-party plugin was no longer compatible (no problem, I dont use it anyway)
Now it is working
Thanks. -
Old C socket program compiles, but doesn't run properly
I have an old C program that uses sys/ipc.h to listen on ports 6666 and ports 6669 for user requests. I have determined that the
program gets to the 'accept' call without error. The return from accept(sockfd, (struct sockaddr *) &cli_addr, &cli_addrlen) is zero
indicating success. Nevertheless, something is wrong, because netstat -a shows nothing listening on either 6666 or 6669, and
telnet to these two ports fails as well.
I've compiled and run the program on Sparc 8 and 9. It is the i86pc architecture I am having a problem with. I tried having root
run it in the global zone in order to eliminate zones as a factor with no success.
This program also uses threads (thread.h) and rpc (rpc.h). Has anyone seen this problem? Does anyone have a suggestion?
GeorgeHi Darren:
Thanks for your prompt supply. I saw no alternative but to start pulling the code apart and I believe I have a solution. I think big-endian as opposed to
little-endian definitely has something to do with it.
Here's what I had to change to make this work:
Original Code: serv_addr.sin_port = htonl(port);
Modified Code: serv_addr.sin_port = htons((short) port);
Converting the port to a short seems to have fixed things. The original code converted the port to a long. -
Group Policy Startup Script Applies My Policy But Does Not Run The Acual Scripts
I have created a basic batch file with msiexec.exe to uninstall a program on startup and then another separate .bat script to install the same program but the newer version. The software I'm referring to has to be completely uninstalled BEFORE
I install the "newer" version of the same program, it cannot just be overwritten. If I run a gpupdate /force on the client computer and restart, the scripts run as they are supposed to and everything works but the problem is that I can't get it to
run on first boot on a computer that has been turned off for months, even after multiple reboots it still doesn't run the scripts. The 3 policies apply to the different computers/users but the scripts don't run. I manage a theme park that is
only open 4 months of the year so the rest of the time the in park PC's are turned off. I have created my OU as "POS Computers & Users" which has all of the computers and users that will take this policy. I also have 3 Group Policy
Objects attached to this OU in Group Policy, 1 is the program uninstallation .bat script policy that runs on startup, 2 is the install .bat script policy that runs after the uninstallation script, and 3 is the Default Policy for the OU. I already have the
"Always wait for the network at computer startup and logon", "Run startup scripts visible"enabled, "Run startup scripts asynchronously" disabled, and "Run Logon Scripts Synchronously" enabled for all 3 of the
policies. They are all "link enabled" and security filtering is set to only the OU I mentioned earlier so that it doesn't affect anyone else. I have the link order set as the script I want to run first as the last and the one I want to run last first
because from what I understand inheritance is from bottom to top. The install file is accessible by everyone with full permissions on our "Shared" drive so I know its not a permissions issue because it runs after a gpupdate /force with a restart.
The scripts are in the proper folder for the policies they are attached to and permissions are fine.
Here is my uninstall .bat script (msiexec.exe /X{14324A6A-BDD1-4F40-8E77-664C8AEEA251} /forcerestart /qb-! ALLUSERS=1 REMOVE=ALL)
Here is my install .bat script (msiexec.exe /i {\\kksrvad\shared\Gatemaster\NewGatemaster.msi} /qb ALLUSERS=1)Can't be done in a login script.
This is a Group Policy issue and not a scripting issue. You do not have a script. You have a command saved in a batch file and you are using a GPO. Not a scripting issue.
