You need to go and do some research first on how to access SMS systems via Java. Take a look here[^] at some of the reference materials and tutorials.

That would seem to be the sensible way to do it; otherwis how would you tell when the count for a single college gets to 8?

Hello Friends
I am crating one applet based application.Now I want to run that on another system where jre is not available.So,can I use jre that Installed on my system by copying to another one and How can I use then that copied jre?
Or is there any other way to bundle jre with application so that when I try to run that application on any other system where no jre then this bundled jre get in use to run my application.
In actual I want to run my applet when My jre is at some different location other than installed one.
Any Help will be appreciated.
Thanks & Regards

I don't think this is possible. Any java app or applet needs to be able to find the registered JRE on the machine where the app/applet is to be run.

Is this an applet or an application?
If it is an application then you can simply include the JRE in a directory along with your application distribution and then run the application from that. The advantage of this is that you know which version of the JRE your application will run against, rather than being at the mercy of whichever random JRE happens to be installed as the default on the target machine. There is no need for any installation process or registration, you can copy the JRE directory and then point your application at this and away you go.
An applet is a different matter. If you want to run the applet from within a browser, then that browser must have a Java plug-in of the correct version installed and enabled. There is no way the applet can do this automatically. Normally, I would expect the browser to prompt the user with a message, something like "A required plug-in is missing for this page". In this case, the JRE does have to be properly installed and registered, and you cannot simply copy it over to the other machine.

Sorry but we do not write code to order. Take a look at the articles here[^] and the tutorials here[^].

Hi all ,
I have the class file (HelloWorld.class) calls a native method, and the native library (Hello-World.dll) implements the native method.
While running the HelloWorld class I am getting following error:
Exception in thread "main" java.lang.UnsupportedClassVersionError: HelloWorld (Unsupported major.minor version 50.0)
Is this error releted to Java version?
I am using JDK 1.6.
|
|
|
|
|
The most likely cause is that the HelloWorld class was compiled to version 1.6 but you are trying to run it with a 1.5 JVM. Although Java is backwards compatible (a 1.6 JVM will run 1.5 code) it does not work the other way round.

Hi all,
Iam getting run time error in following function in jni.h:
return functions->FindClass(this, name);
Following is the FindClass() function call fron my cpp file:
cls = (env)->FindClass(servParams[i].lib);
Plz help , I am new to JNI Programming.

What is the actual error code or message that you receive? Also check the values of the various parameters you send to your functions. I also do not see the connection between the above two statements, the first accepts two parameters and the second passes only one.

Actually in jni.h following is the definition of FindClass
jclass FindClass(const char *name) {
return functions->FindClass(this, name); }
Following is the Error message I am getting at 'FindClass(this, name)':
Unhandled exception at 0x60edf3a0 (xxx.dll) in yyy.exe: 0xC0000005: Access violation reading location 0x00000000.
|
|

OK so trying to read memory address 0 indicates you have an uninitialized pointer. Check your code to see where your pointers are set up. More specifically check the code where you are calling FindClass() and ensure that your name parameter actually points to something.

Hey Richard,
Here in 'FindClass(this, name)' name parameter is pointing to some value but 'this' pointer is pointing to 0x00000000.
Plzz help........

You will need to show some of your code, both Java and C for me to have any possibility of seeing how you are getting to this point.
BTW please don't rely to your own messages as I don't get a notification of the update.

I am not posting the entire code,Tell me if its sufficient
Following is my Code:
int MyAPI(Parameters* Params, int i) {
.
.
.
JNIEnv *env;
JavaVM *jvm;
JavaVMInitArgs vm_args;
char clspath[400]="-Djava.class.path=";
resCheckVM = JNI_GetCreatedJavaVMs(&jvm, bufLen, &nVMs);
if( resCheckVM < 0 || nVMs < 1 )
{
.
.
.
JNI_GetDefaultJavaVMInitArgs(&vm_args);
fflush(stdout);
res = JNI_CreateJavaVM(&jvm,(void**)&env,&vm_args);
if (res < 0)
fprintf(stderr, "Failed to Create JVM.\n");
}
else
{
fflush(stdout);
res = (jvm)->AttachCurrentThread((void**)&env, NULL);
if (res < 0)
fprintf(stderr, "Failed attaching current thread to JVM.\n");
}
cls = (env)->FindClass(Params[i].lib);
if (cls == 0)
{
fprintf(stderr, "Can't find Prog class \n",Params[i].lib);
return 1;
}
{
fprintf(stderr, "Can't find function \n");
return 1;
}
.
.
.
return 0;
}
Here I am getting this message "Failed to Create JVM."
Then a run time error at FindClass(Params[i].lib).

Well, I don't think anything will work after this. If you have not managed to instantiate the JVM then your application should die as there is nothing further it can do.

Hey Richard,
Can u tell me the reasons why JVM creation might have failed , so that i can loook for it .

Ravi

You should check the JNI error code returned from your call to JNI_CreateJavaVM(); I would also check the values of your input parameters prior to the call to ensure all are correct.

Ravi,
I have been doing some more testing and figure that some of your code is not needed and some needs correcting.
- The call to
JNI_GetCreatedJavaVMs() will never succeed as you do not have any created VMs at that point. Also this call is not used in newer versions so can be removed. - The call to
JNI_GetDefaultJavaVMInitArgs() is no longer necessary and does not serve any purpose. - Before calling
JNI_CreateJavaVM() you need to initialize your vm_args structure with the correct values as described here[^]
