JNI Application running in ms-dos but throws an exception in applet

Hi! I have a java application which calls a DLL using the JNI. This works perfect if I execute the java program from my command line (in ms-dos) But when I try to do it in an applet, it indeed runs and do everything ok, but at the end of the execution I get a EXECUTION_EXCEPTION.
This is how is working:
1.- jnidllmyclass, this is where I call the native method of my DLL
2.- intermediate DLL which writes to files to c:\temporal and it calls several functions from other DLL
3.- other DLL which writes more files (among other things)
4.- applet class with a call to jnidllmyclass
Now the DLL what does is to open a connection to a usb scanner, then send commands to it to scann somethings, save front and back images to c:\temporal (obviously, all of this is done in the user system, using certificates) and write other file and close the connection. This works! it write the images well and write everything... but after that the exception arises... I have doubt of what is it, because if it does all, what is causing the exception?
Thanks for your help!

Hi! Applet can access the DLL. The scanners works, but the C DLL throws an exception. Nevertheless, I've managed to see what was going on. When you click a JButton in a GUI, it enters only one to the actionlistener, but if this is done in an Applet, enters twice, so... the first time worked fine, but the second no because there was nothing to scann.
This theme is a bit creepy, if you want help just ask! I give snippets, not just advices... I hate those people, so fell free to ask.
Greetings!

Application call to ODBC SQLSetEnvAttr function throw HY011 exception

Hi All,
I try to use odbc driver manager in my .Net Application.first My .Net runtime is 3.5, odbc function calls(unmanaged functions are imported to .Net application by dllimport attribute)can work well.but when .Net runtime is upgraded
to 4.0,SetEnvAttr function calls
return SQL-ERROR and I call SQLGetDiagRec function get this error information:Operation invalid at this time.sqlstate value is HY011.
below is my code fragment:

my operation system is win7 64bit. Could someone help me? thanks

I already fixed this problem.

I replace ushort datatype with long datatype.So it works well

VI server application runs under debug mode but not other wise

I have an application which uses VI server to call vi's on my targets hard drive. When I run this using the highlight execution( or debug ) this works OK, however when I run without this I get error 66, connection closed by peer. When I look at my target using a direct monitor connection I get various messages relating to memory errors. I have run virtually the same code calling a simpler application and this seems to work fine, however when I simply target the RT engine with the same code ( using the RT comms wizard construction) I don't get a problem. This should, I think, be using the same amount of memory. What is the best was of assessing the memory available against the memory required? Do anyone have a
ny ideas as to why the VI should run with execution highlighted and not without. I have tried adding delays so simulate this but it doesn't seem to work.

Check out this KnowledgeBase article. It describes how to enable a memory monitoring tool that might help solve your problem.

I had my screen sectioned with an application running permanently in it and have lost it, please can someone tell me how to get it to do that again? Thank you.

Hello,
At some point a while ago I somehow mistakenly must have clicked on something in error and suddenly my Google Analytics programme (which is shown in by bookmarks at the top of the screen) was displayed in a section of the browser window to the left - the browser screen was split into two sections, with the google analytics program running in the left section and the right section was my regular browser window where everything ran as normal.
I have no idea how this happened, but love it and have come to really appreciate it. However I've just changed computers, operating systems and allsorts and now I've got everything back on track that window has sadly gone and I cannot find how to get it back. I've searched through every option I can find and cannot figure out how to do that again!
Can anyone help please? :-)

Hi jscher200,
Thank you for your reply, sorry for the VERY late late response, but I have just figured out how to control this separate 'panel'. I find it really useful for monitoring Google Analytics in as it can just sit there running. It does have its limitations, as it's a limited size (you can't expand it to full screen view), so you can only ever see a vertical section of a website and need to scroll to look to the right or left, but I have the live view of people accessing my website running on there and if the numbers start racking up at any time, I can scroll to look and see what pages they are accessing, where they've been referred from, etc.
To get it to work, you save a website address in the Bookmarks Toolbar and when you can see it sitting on the toolbar at the top of the screen with its little icon, right click on it then click 'properties', then tick the box 'Load this bookmark in the sidebar'. The next time you click on this bookmark to open the website, it will load in this sidebar, which looks like a separate 'window' but is immovable. You can only have one sidebar application running at a time, but can change it by right clicking on the bookmark you want to load in there and it will then change to that one next time you click on that bookmark.
I hope this might be useful to others, as I asked for help with this on loads of forums and not one person knew that this existed - even really skilled techies!

Hi guys
I Think that is a simple error, but I don’t have enough knowledge in .NET apps.
I make an console app that use Remote Authentication in SharePoint Online Using the Client Object Model, that a I downloaded from MSDN.
This App run ok.
But when I like to make a Windows From App. This component send me an error in Application.Run(DisplayLoginForm)
This err msg :
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll
Additional information: Starting a second message loop on a single thread is not a valid operation. Use Form.ShowDialog instead.
Is there any way to use a form inside a windows form?
Thank in advance

Hi,
Based on the error message, please do as following:
1. Check your code logic below:
void btn_Click(object sender, System.EventArgs e)
Thread t = new Thread(StartMyForm);
t.TrySetApartmentState(ApartmentState.STA);
t.Start();
public static void StartMyForm()
Application.Run(new MyForm(..));
2.Try to add the following code line in your code.
Application.Restart();
If the issue still exists, please provide your requirement and code for a further research.

Application runs slower on Solaris

We have developed an Application in Java (Servlets, JSP & Core Java classes including thread).
My Application runs fast on Windows, but its terribly slow on Solaris. When the application is run on Solaris the CPU usage is very less around 3 to 5 % only and there is no major io bound operation also. Please comment on this behaviour when am running the application on Solaris.
For eg: A while loop in my program took around 16 msecs to execute in Windows machine, but the same while loop is taking 250 msecs to run in solaris.
Note: The solaris machine is very powerful than the desktop windows machine.
Thanks & Regards,
Salin

Which version of Solaris are you running and what threading library is currently in use? Did you use some profiling application to arrive at the benchmark results you obtained or some other means were used? Does the code within the while loop call any classes making use of Java threads and synchronization mechanisms?

Transport.send(Message) sends mail but throws exception

Is it possible in any scenario that Transport.send(Message) method deliveres the message successfully, but throws an exception also?
Any help is appreciated. Thanks.

Yes, but only if you've configured it to do so.
See the javadocs for the com.sun.mail.smtp package for the property
you can set to cause it to do that.
If you haven't set that property and you're seeing that behavior, please provide
more detail, including especially the protocol trace.

JNDI: DirContext::list throws on exception when existing context is in LDAP

I was able to import tutorial.ldif using LDAP Browser/Editor without incident:
http://www-unix.mcs.anl.gov/~gawor/ldap/
My LDAP now has the following tree:
o=JNDITutorial
ou=Groups
5 cn entries
ou=People
10+ cn entries
However, when calling DirContext::list("ou=People"), it throws the following exception message:
javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object]; remaining name 'ou=People'
Here is the code:
     final static String ldapServerName = "backbone.seamonkey";
    public static void main(String[] args) {
     // Set up the environment for creating the initial context
     Hashtable env = new Hashtable(11);
     env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
     env.put(Context.PROVIDER_URL, "ldap://" + ldapServerName +"/o=JNDITutorial");
     try {
         // Create initial context
         DirContext ctx = new InitialDirContext(env);
         // Return enum of people, but throws an exception...
         NamingEnumeration people = ctx.list("ou=People");

I tried the same with a known LDAP service: OpenLDAP.org, and I get the same exception NameNotFoundException thrown with the following code:
     final static String m_ldapServerName = "OpenLDAP.org";
    public static void main(String[] args) {
     // Set up the environment for creating the initial context
     Hashtable<Object, Object> env = new Hashtable<Object, Object>();
     env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
     env.put(Context.PROVIDER_URL, "ldap://" + m_ldapServerName + ":389/");
     try {
         // Create initial context
         DirContext ctx = new InitialDirContext(env);
         // Return enum of people, but throws an exception...
         NamingEnumeration people = ctx.list("ou=People");

     options[1].optionString = "-Xnoagent";
     options[2].optionString = "-Djava.compiler=NONE";
     options[3].optionString = "-Djava.class.path=.";
     options[4].optionString = "-Xrunjdwp:transport=dt_socket,address=8888,server=y,suspend=y";
In the debug window in eclipse i have created a new config. under remote java application. I have set the connect tab = myproject.
Connection type = Standard(socket attach) and connection properties: host = localhost , port=8888.
Any help?

It looks like you are doing basically the same thing as we are doing, and it seems to work for us. Do you see a message from the JVM that says:
Listening for transport dt_socket at address: 8888
The one strange thing that we are seeing is if we throw an exception in Java and clear it in C++ (using ExceptionClear) the subsequent entry into the eclipse debug session behaves very strange.
Anyway, here is what we are doing:
J2SE 5.0
Eclipse Version: 3.1.0 Build id: I20050401-1645
jvmOptions[0].optionString = "-Djava.compiler=NONE";
jvmOptions[1].optionString = (char *)classPath.c_str();
jvmOptions[2].optionString = "-Xdebug";
jvmOptions[3].optionString = "-Xnoagent";
jvmOptions[4].optionString = "-Xrunjdwp:transport=dt_socket,address=8888,server=y,suspend=n";
jvmOptions[5].optionString = "-verbose:jni";
memset(&vm_args, 0, sizeof(vm_args));
vm_args.version = JNI_VERSION_1_4;
vm_args.nOptions = JNI_ARG_SIZE;
vm_args.options = jvmOptions;
vm_args.ignoreUnrecognized = JNI_TRUE;
The eclipse remote java application is the same as your:
Connection type = Standard(socket attach)
Connection properties: host = localhost , port=8888.

Hello,
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Application running slow in ver 1.5, 1.6 but not in 1.4

We have a application that was running very slow when we used any version sun java instead of MS java in IE6 SP2.
I removed MS Java from IE and installed Sun java 1.4.2_16 and the applications starts in under 10sec's.
But we had to test the other version of java as well, i then installed the other versions from 1.5 update 14 to 1.6 update 4 and the application takes about 30 to 40 sec to load the web page.
I then looked at the development version of java 1.6 update 10 and version 7. In 1.6 update 10 the application would load but would not refresh the applets it would just hang. In version 7 the application would not start up at all.
In all the versions i increased the memory parmeters from 128 to 256 and in version 1.6 i changed it to -Xmx300m as well but still the application was slow loading. Removed all the versions and reinstalled 1.4.2_14 and the application works fine and loads up under 10 sec.
Does any one have any idea why this is happening.
IE 6 sp2
XP sp2 been used.

You should try profiling the startup code.
As a first go around, you might try getting a stack trace during the startup process and look for locks (see jstack).
If your application is built on Swing, it's my understanding that the later versions of Java are more strict about use of the Event Dispatch Thread--pay particular attention to activity off the EDT locking the thread.

When my application running, some of CPU have IDLE state = 0 and hold the CPU while another CPU have IDLE state 100. I think this is my bottleneck but I cannot find any solution for solve that.

Please help me find the bottleneck of my T5440 server?Thanks so much for all your help.

Moderator Comment and Action:
@ O.P.,
You cross-posted this to at least two other forum web sites:
http://www.linuxquestions.org/questions/solaris-opensolaris-20/application-running-too-slow-on-sun-sparc-t5440-but-run-normal-on-sun-m3000-4175411155/
http://www.unix.com/solaris/189945-application-running-too-slow-sun-sparc-t5440-but-run-normal-sun-m3000.html
... and didn't think that was important enough to simply mention the fact.
Timestamps suggest that OTN was the last place you posted to.
Poor forum etiquette.
Why would anyone spend the time to try to give help that you have already received elsewhere? That's a waste of their time.
(Yes, you already received the suggestion to use Dtrace in one of those other sites.)

Application Runs Under Windows 8.1 But Not Under Windows XP (I Know XP Is Deprecated)

The problem is with the obtuse error message put out by Windows's program loader. It reads, in part, "..is not a valid Win32 application." The application runs everywhere except on Windows XP. Looking for root cause of the problem. It's a very
simple application. Only a few lines of code.
C:\Packaged-Software\32-BIT\Reboot.exe is not a valid Win32 application.
Proposed nature of the problem:
1. The file was downloaded from a website but the download was incomplete.
2. The full file system filename path contains bad characters such blank space.
3. Visual Studio constructed an application that won't run anywhere much less on XP.
4. The supporting libraries are not properly installed (e.g. .NET Framework4, and VCREDIST).
Retorts:
1. The file wasn't downloaded from a website and is intact.
2. The filename path doesn't contain any spaces.
3. The application runs under Windows 8.1. Also on Windows 7.
4. The supporting libraries are properly installed.
So, what's the problem? One surely will not discover the root cause from "not a valid application."
Body must be 4 to 60000 characters long. I had put the code here. It isn't 60000 character long. But it validated as if there are more than 60000 characters. Sorry for the incomplete submission due to website construction error.

Hi F7H2fw,
How did you develop the application ?
Here is a similar symptom and this may explain the issue somehow:
Setup.exe is not a valid Win32 application
http://blogs.msdn.com/b/vsnetsetup/archive/2012/10/16/setup-exe-is-not-a-valid-win32-application.aspx
I suspect there is a compatibility issue here .
Considering this is more likely a developing issue .It is recommended to ask for help from our MSDN Forum .They are more familiar with the developing issue .If it is possible ,please attach the code in that thread .Thanks for your understanding and cooperation.
