Cannot launch my java application

Hi All. I have made a Java application using NetBeans.
The application, with NetBeans works fine. It imports many jasperreports classes included in my project by setting in the project properties the Compiling source to the various jar archives:
jasperreports.jar
common-digester-1.7.jar
common-collections-2.1.jar
common-logging-1.0.2.jar
common-beanutils-1.5.jar
When I launch with NB it works as I designed it.
And now comes the problem.
With NB I build the project and it builds my PrintReport.jar.
As I try to launch it with
- java -jar PrintReport.jar
it prompts this error:
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource at printreport.PrintReport.main(PrintReport.java:45)
that line is exactly where I create the instance of the class containing all JasperReports refs.
Can anyone help me launch it correctly from command line?
Thanks, Angyel

I tried same thing but it is not working for me. It is not refering the Classpath which I specified in Mainfest file.
Manifest-Version: 1.0
Class-Path: jaxrpc.jar activation.jar axis.jar commons-logging-api.jar discovery.jar mail.jar saaj.jar soap.jar wsdl.jar

Cannot launch an java application

Hi there,
I'm trying to run a java program after updating to Yosemite. I already downloaded and installed the latest JRE 8 update 25. Trying to run the application results in the following console error (nothing happens on the screen):
20/10/14 21:32:56,584 com.apple.xpc.launchd[1]: (jclient.LoginFrame.63932[1450]) Service exited with abnormal code: 127
Can someone please help!

Hmm, only way I know would be a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

Just be sure to select Preserve Users & Settings.

How to launch my java application in a web browser?

Hi. I try to launch my java application, e.g. "HellowWorld.java", using web browser.
1. How can I change my java application program to java applet in general way?
I read "Java: An Introduction to Computer Science and Programming, Third Edition"
by Walter Savitch and found page 803 - "Converting a Swing application to an applet".
My question is how I can know which class should be removed or not such as using JApplet instead of JFrame. Are there general rules about this?
2. I found "AWT only" tutorial had some example lauching application using "AppletButton".
How can I use this method to launch "HelloWorld.class"?
http://java.sun.com/docs/books/tutorial/information/download.html#OLDui
(after extracting zip file) -> ../OLDui/layout/card.html
3. (continued 2) Can I use above method to embed applet into web browser?
For example, java Swing application -> applet using "AppletButton" -> web browser using "<applet></applet>" tag.
I'd appreciate any partial anwers of these questions or other suggestions.
Thanks.

Thanks! Here is what I got from your help.

Launching a java application in another PC

Hello everybody
I want to know what to do if I want to launch a java application in a new PC which has anything installed in it.
Thanks

My problem is that if there is a new PC , nothing installed in it, can I launch a java application in it ?
My friend asked me if I can build an application in java which I can use in any PC and the application will do something like an installation. In fact he wants to know if java can build an installation like application which will install for example a software on a new PC.
I think I told you more clearly the situation.

To launch a java application in Windows environment

hello,
I need to distribute one stand alone application, that I made using NetBeans, for sale it.
I know that this is not a so simple problem, because delivering the program to one client you cannot simlpy say him to launch the jar file....
I saw that, in the Windows environment, program like eclipse or netBeans run thruogth an .exe file, that I think is a program that its purpose is to define the java environment for the application in the particular host operative environment .
Perhaps they are corporations like InstallShield (now Macrovision) that sale programs to solve this type of problems..., and I already used this type of programs to install some my
applications that I coded in languages different than java.
But before to look for one of them, I should like have more informations how this problem fits in java language, knowing that java is different to other languages because use JRE and have proper tools, how JWS and JNPL, that concern with this problem.
...Looking in the forum I had not much help..., but I saw that someone uses to write launchers program in different language, like C, as well I had not so much detailled instructions about how to do it.
In order to solve my problem I should like have, from some one that already made it, some general information about how he realized the commercial installation of java applications in the most used Operatve Systems (particullary Windows), and possibly to have links to web sites for good explanations, including advantages to buy apposite commercials installation programs too.
thank you very much
tonyMrsangelo

You can distribute it as an executable JAR so users will run it by double clicking. The would be required to have JRE installed.
You can distribute it online via WebStart. Users need JRE but it's easier to manage updates and distribution of new versions.
You can distribute it with AjaxSwing, a product that deploys Swing applications as AJAX websites so you don't need JRE at all.
You can create EXE files using many of the products available. Google for it and you'll get lots of hits.

Installation fails with "Cannot launch the Java Virtual Machine"

I'm trying to install OAS 10.1.3.1. on Windows XPbut after copying all the files the installer starts complaining that it cannot lauch the Java Virtual Machine. Eventually, the process gets to the configuration step where it succeeds with one configuration, then fails with the next, and then finally goes into an eternal loop.
When launching the installer it claims that my environment successfully passes all test for memory size, etc.
Is this a known problem? Is there any way I can get more info about the reason why the JVM could not get lauched? I searched for information in the logs without success. I also tried to play around with the PATH environment variable since I saw some installation note saying that includingthe jre/bin path here could help, but it did not help.
Could anyone, please, give me a hint of how to complete the installation successfully?

Thanks for the hint.

Launching a java application from another java application

Hi,
I'm facing an interesting challenge :-)
Inside a Java application, I want to start another java application.
Possible solutions in my list :
1. Using jakarta commons launcher.
2. Runtime.exec (make the code platform dependent).
3. Starting the main method of the other app by create a new Thread inside the current app
4. I know people did this by calling an ant target from the java application but I don't have
any sample code, I appreciate any sample code for it.
Thanks,
Ali Salehi

That is an iteresting challenge :)Don't be mean; he's polite, done some investigation and taken the trouble to be clear. The question, presumably, is "has anyone got a different solution or a preference as to which of these is the best?"
In which case, my advice would be to say that invoking main in a separate thread is fundamentally different from Runtime.exec() because the former would run in the same JVM. Is this what you want? If one app has the other on its classpath then do they need to be separate apps? Could they be modules of a single app?

My sysAdmin tells me he cannot cluster my java application

Hi
I have a small java application which reads files from a (ftp) directory, validates them and writes them to disk again. This application is being called from a CRON scripts on both servers which runs it every minute. Our hosting company says that on the application needs to be run on both clusterservers at the same time. This causes synch problems when reading the file. 2 applications try to access the same file at the same time.
How can he make the second server start up the application when the first goes down?
Our hostingcompany says that my application is not cluster-aware and that it's impossible to configure the server to start/stop my application.
Can somebody please help me with this?
thanks

there are two ways to approach this (in sun cluster 3.x)
that come to mind.
the first is a quick hack that requires you to use a wrapper
script for your cron job (ie, run this script with cron, and
use this script to start your java prog).
here's the gist of it:
----------------------------->8---------------------------------------------------
#!/bin/sh
# wrapper script for cron jobs on 2-node cluster
# >2 node cluster requires more work
# exit if cluster not active on this node
thisState=`scha_cluster_get -O NODESTATE_LOCAL`
if [ "$thisState" != "UP" ] ; then
exit 0
fi
# find out the node ID of this system
thisNode=`scha_cluster_get -O NODEID_LOCAL`
# if this is not node 1, check to see if node 1 is active
if [ "$thisNode" != 1 ] ; then
node1Name=`scha_cluster_get -O NODENAME_NODEID 1`
node1State=`scha_cluster_get -O NODESTATE_NODE $node1Name`
# if node 1 is active, it will run the program, so
# we can quit
if [ "$node1State" = "UP" ] ; then
exit 0
fi
fi
# at this point, we know this node is active, and is
# either node 1, or is the remaining active node
# in either case, run the program
exec /path/to/my/prog
----------------------------->8---------------------------------------------------
you could even make this a generic wrapper by doing
"exec $@" at the end & supplying the normal program
path & args as arguments to the wrapper script...
the 2nd solution is to essentially write your own "cron":
in other words, a long-running process that simply sleeps
in between trying to run your program (or rewrite your
program to run forever & check the ftp dir occassionally).
then you can use the standard tools to make the program
highly available (scdsbuilder, etc)

How to launch a java application from Microsoft SQL Server

Hi everyone
I noticed the following line in a trigger will launch an executable.
EXEC master..xp_cmdshell '"C:\Program Files\SkillSets.exe"', NO_OUTPUT
Does anyone know if this same statement will launch a java program? Or does anyone have any positive experience with that ?

yes...
check this basic example:
public class GoodWindowsExec{
public static void main(String args[]){
if (args.length < 1){
System.out.println("USAGE: java GoodWindowsExec <cmd>");
System.exit(1);
try{
String osName = System.getProperty("os.name" );
String[] cmd = new String[3];
if( osName.equals( "Windows NT" ) ){
cmd[0] = "cmd.exe" ;
cmd[1] = "/C" ;
cmd[2] = args[0];
}else if( osName.equals( "Windows 95" ) ){
cmd[0] = "command.com" ;
cmd[1] = "/C" ;
cmd[2] = args[0];
Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]);
Process proc = rt.exec(cmd);
// any error message?
StreamGobbler errorGobbler = new
StreamGobbler(proc.getErrorStream(), "ERROR");
// any output?
StreamGobbler outputGobbler = new
StreamGobbler(proc.getInputStream(), "OUTPUT");
// kick them off
errorGobbler.start();
outputGobbler.start();
// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
t.printStackTrace();

JNI launching a java application

Being a java newb, a lot of the JNI code confuses me.
I have a java application that I wish to run through a JNI wrapper.
What is the most simple C++ code that will enable me to do so.
Also most of the code posted for doing this uses various header files. Where can one find these header files, and also which compiler is needed for compiling the wrapper. I assume Gpp or similar - is this assumption correct?

When using both of those examples I get numerous compiler errors - using the sun invocation api example;
#include <jni.h>       /* where everything is defined */
    JavaVM *jvm;       /* denotes a Java VM */
    JNIEnv *env;       /* pointer to native method interface */
    JavaVMInitArgs vm_args; /* JDK/JRE 6 VM initialization arguments */
    JavaVMOption* options = new JavaVMOption[1];
    options[0].optionString = "-Djava.class.path=/usr/lib/java";
    vm_args.version = JNI_VERSION_1_6;
    vm_args.nOptions = 1;
    vm_args.options = options;
    vm_args.ignoreUnrecognized = false;
    /* load and initialize a Java VM, return a JNI interface
     * pointer in env */
    JNI_CreateJavaVM(&jvm, &env, &vm_args);
    delete options;
    /* invoke the Main.test method using the JNI */
    jclass cls = env->FindClass("Main");
    jmethodID mid = env->GetStaticMethodID(cls, "test", "(I)V");
    env->CallStaticVoidMethod(cls, mid, 100);
    /* We are done. */
    jvm->DestroyJavaVM();and I get the following errors:

How can I Launch a Java application that I have written using an icon

I have just finished writing a Messaging system like Ms Outlook written completey in Java. To run my application , I would normaly type: java and then the class containing the main method eg java LogonFrame.
How can I launch my application by just clicking on an icon ?.
How can I also package and install this application the way most conventional application are packaged and installed. Do we have a sort of "java Installer" ?.
Thank you.

Just make a .bat file. Open notepad, type something like
@echo off
javaw -classpath %~d0%~p0 Package.MainClass %1
Now make a shortcut to this file. Rightclick the shortcut and select start in "minimized". Thats it...
