I have a jar application which process and converts file into csv file. I have made it to run in windows service using Java Service Wrapper. It got installed my jar application successfully when I run "InstallApp-NT. Bat" file and starts running my application when I run "app" command.
But when I try to start the service in services, its not starting and showing following message in dialog box<
Windows could not start the generic Preprocessor application on Local Computer. For more information, review the System Event Log. If this is a non-microsoft service, contact the service vendor, and refer to service-specific error code1
I have the system log file and it showing the below error message

I don't think any error in application code because it running fine when run "app" command. Please help what I should now. Thanks in advance.
I am using the following code in com.dnb.genericpreprocessor.process.ProcessRunner class.
String projectHome = "D:\BL";
System.setProperty("project.home", projectHome);
System.setProperty("log.home",System.getenv("DBE")); ---> DBE is the envirinment variable I created in user variables.
When I run the application by giving app command... Its running the application by printing the environment value but showing the same error when I start it in service.
Answering your question update that you phrased as an answer, you need to ensure that the variable is in fact set in the specific environment where you are running the application. It appears that it is not. In fact, to avoid the NullPointerException, I would modify your code to something like:
String loghome = System.getenv("DBE");
if (loghome == null) {
// LOG A COMPLAINT that the environment variable is not set
loghome = "some reasonable default value";
}
System.setProperty("log.home", loghome);
so at least your application won't fail with an obtuse NPE if it is executed in the wrong environment.
Check com.dnb.genericpreprocessor.process.ProcessRunner if that is your code and see what data you are setting in System property. NullPointer is telling that the key or the value you passed is Null.
Check your wrapper.config; you need to have all the necessary jars in order, and each with their own index number (for some reason):
wrapper.java.classpath.1=../lib/wrapper.jar
wrapper.java.classpath.2=%JAVA_HOME%/lib/tools.jar
...
Just a first thought.
I am not familiar with the proprietary solution you are using, but it seems you somehow configured it wrong.
Looks like some parameter the wrapper should have is null and is propagating all the way up until the system is trying to set it as property.
Maybe you should put your 'DBE' enviroment in the system variables not user variables.
Windows service starts at system account.

I am implementing liblinear in windows app using visual studio express 2013 for windows. After installing liblinear using nuget package manager(link is https://www.nuget.org/packages/Liblinear/) I was trying to use it:
using de.bwaldvogel.liblinear;
And in the code I typed :
Parameter para = new Parameter(SolverType.MCSVM_CS, 1.0 , 0.01);
but it gives error while running, stating:
An exception of type 'System.TypeLoadException'occured in FileExplorer.DLL but was not
handled in the user code.
Additional Information: Could not load type 'System.Runtime.Serialization.Iserializable
' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'.
If there is a handler for this exception, the program may be safely continued.
Also when nuget package is installed there are no errors but there are warnings stating
Reference to type 'System.Runtime.Serialization.ISerializable' claims it is defined in
'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\WindowsPhone\v8.0\mscorlib.dll',
but it could not be found (in IKVM.OpenJDK.Core.dll)
Reference to type 'System.Runtime.Serialization.SerializationInfo' claims it is defined
in 'c:\Program Files (x86)\ReferenceAssemblies\Microsoft\Framework\WindowsPhone\v8.0
\mscorlib.dll', but it could not be found (in IKVM.OpenJDK.Core.dll)
Could anyone help me out with this? I am developing app for windows phone 8.0.
Unfortunately, the ISerializable interface is not available for Windows Phone 8.x. :( Check out the Platforms section here. This thread has additional info as well.
Is the liblinear NuGet package supposed to be supported on Windows Phone? If so, I would get in contact with the author of the package directly.
I just downloaded some java applets from this site: http://www.surendranath.org/Apps.html to run them offline on my laptop. Take for example this one: http://www.surendranath.org/Applets/Oscillations/Lissajous/Lissajous.html
By inspecting the source code I downloaded the file: wget http://www.surendranath.org/Applets/Oscillations/Lissajous/LissajousApplet.class
Then I tried it to run it on my ubuntu box via gappletviewer-4.8 -code LissayousApplet.class
However I got the following error message:
Exception in thfully qualifiedread "main" java.lang.NoClassDefFoundError: loaded class LissajousApplet was in fact named Applets.Oscillations.Lissajous.LissajousApplet

So what is the correct way to run this applet offline? Running it online within my browser and the icetea plugin works. However I need a way to run it offline.

Trying the fully qualified class-name results in:

We have coded and run a dynamic web application using MAPSERVER(Version 6.0.1) on windows platform using Java Technology. Now, there is need of deploying it on Ubuntu 11.10. We have installed Apache Tomcat 6.0, Mapserver 6.0.1, Apache 2.0, and FWTools-2.0.1(As this package contain all required tools for mapserver if I am not wrong, so I didn't feel any other tools to be installed). We have deployed the war file(and put application without) in Apache Tomcat 's Webapps folder. I even got the index page which dont have code related with mapscript api. But while fetching the other servlet with mapscript we are getting following error...
java.lang.UnsatisfiedLinkError: no mapscript in java.library.path
java.lang.ClassLoader.loadLibrary(ClassLoader.java:1681)
java.lang.Runtime.loadLibrary0(Runtime.java:840)
java.lang.System.loadLibrary(System.java:1047)
edu.umn.gis.mapscript.mapscriptJNI.<clinit>(mapscriptJNI.java:23)
edu.umn.gis.mapscript.mapObj.<init>(mapObj.java:283)
Again while refreshing the browser page where the above error was displayed, I got a change,
java.lang.NoClassDefFoundError: Could not initialize class
edu.umn.gis.mapscript.mapscriptJNI
edu.umn.gis.mapscript.mapObj.<init>(mapObj.java:283)
I searched on net about the above problem. But finally blank. Please, provide idea about the above problem.
I'm not going to explain why you're getting the UnsatisfiedLinkError, but instead I'll explain why you are getting the NoClassDefFoundError when you reload the page.
A NoClassDefFoundError with a message Could not initialize class ... is thrown by the JVM when it attempts to initialize a class that it has already tried and failed to initialize.
The first of your two stacktraces contains the line
edu.umn.gis.mapscript.mapscriptJNI.<clinit>(mapscriptJNI.java:23)
The method name <clinit> denotes the static initializer, of the class mapscriptJNI. So, at the point that the UnsatisfiedLinkError was thrown, the JVM was trying to initialize this class. Looking at the error message, it seems that this static initializer tried to load the native code library mapscript but failed.
This UnsatisfiedLinkError causes the mapscriptJNI class to fail to initialize successfully. The JVM keeps a record of all classes that fail to initialize, and if you attempt to initialize one of those classes again, you'll get a NoClassDefFoundError with a message saying that it could not initialize that class.
When you refresh the page, you end up causing the JVM to attempt to initialize the class mapscriptJNI a second time. Of course, this class failed to initialize the previous time. Your second stacktrace contains exactly the error I've described.
In short, the UnsatisfiedLinkError is the real error here. Fix that and the other one will go away.
I would check the following 2 items:
Is the mapscript.jar file on Tomcat or at least your webapp's classpath? (NoClassDefFoundError is your big clue here)
Is the libmapscript.so on either your LD_LIBRARY_PATH or -Djava.library.path? (UnsatisfiedLinkError since the shared object cannot be found)
Try having a look at this post, near the Running Java Mapscript (on Linux) section.
Hope that helps!
I am having trouble setting up the Php-Java Bridge setup properly.
I will explain what I have done.
My site is in pure php
For our payment transaction process we need to set up a php-java bridge
I followed this link to setup the bridge PHP-JAVA BRIDGE INSTALATION.
Here I learned that I need to have a private jvm to install the bridge.
So 1st i installed apache-tomcat-6.0.14 in Private JVM using my c-panel. After instalation it asked me to Map a domain to private JVM. So I mapped my domain example.com (which is the only option available) to it.
Then it asked to enable a traffic redirection from Apache web server to my Java application server (there was a check box and i clicked it)
Finally it asked me to deploy the WAR File (JavaBridge.WAR was my file) and everthing seems fine
Now when i go to http://example.com/JavaBridge/ I could see the javabridge examples and it works fine.
SO FAR SO GOOD
Now my problem starts here when I try to access a java class file from php. A sample test.php is what I create and put the following code into it.
<?php
require_once("http://example.com:portnumber/JavaBridge/java/Java.inc");
$System = java("java.lang.System");
echo $System->getProperties(); //This Part echo's correctly and shows the data so it means i can access Java.inc Correctly
$path_e24class = getcwd(). '/e24PaymentPipe.class'; //This part fails both test.php and java class file e24PaymentPipe.class are in the same directory in publich_html folder
java_require($path_e24class);
$pipe = new Java("e24PaymentPipe");
$pipe->setAction("1");
?>
My site contents reside in the public_html folder and the WAR file are deployed in private jvm.
These are the error message am getting.
1) Warning: java_require() not supported anymore. Please use tomcat or jee hot deployment instead
Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: CreateInstance failed: new e24PaymentPipe. Cause: java.lang.ClassNotFoundException: e24PaymentPipe VM: 1.6.0_22#http://java.sun.com/" at: #-10

Finally I don't know much about the java. So am stuck here not knowing what to do.
Here is a great step by step tutorial you can follow, which shows everything required! It is a little old (2007) but helped me a while ago.
There is also another option. You can install Apache Tomcat and deploy your war there. You can have even multiple tomcat instances simultaneously with your httpd running at the same time on the same machine, as long as you respect the port settings. You can even front them with Apache httpd.
you can try this:
package your code to jar, and copy it to java.ext.dirs which you can found in JavaBridge.log
copy the related class libraries to java.ext.dirs
restart the service of JavaBridge
good luck!
<?php require_once("JavaBridge/java/Java.inc");
try {
$hd = new java("hdfs.HDFS");
$hd->get("hdfs://master:9000/user/hadoop/test-in/logo_cn.png", "/home/hadoop/1.png");
} catch (JavaException $ex) { echo "An exception occured: "; echo $ex; echo "<br>\n";}
?>
You can use this php implementation on github that works with php 5.3.
See credits on the git readme for more information.
You can try this; put the JavaBridge.jar in tomcat's lib folder e.g. apache-tomcat-7.0.12/lib.
Restart tomcat server and then,
$pipe = new java("com.aciworldwide.commerce.gateway.plugins.e24PaymentPipe");
$pipe->setAction("1");
This way I created the php version of the object.
Why don't you put the e24PaymentPipe class in your Java application's classpath and skip the two lines below:
// $path_e24class = getcwd(). '/e24PaymentPipe.class';
// java_require($path_e24class);
$pipe = new java("fully.qualified.classpath.e24PaymentPipe");
You are mixing PHP side and Java side operations. in theory the java_require (which is deprecated) was designed to work on the Java side. You are specifying a PHP side path.
You can save yourself a lot of grief by using a pure PHP implementation of the e24PaymentPipe library.
Disclaimer
The link is to my github repo of the library, but I did not write it. See the readme in for original credits.
I'm trying to optimize an application by binding its threads to different cores. To begin with, I would like to bind the entire application to a single core using the Affinity-3.0.6 package from OpenHFT.
So far I've had no luck. At first I imported the package and tried the command
AffinityLock al = AffinityLock.acquireCore();
was warned about not having JNA access, so I downloaded the jna-4.2.2 package and imported it as well.
After the second import, the same command gives the following error:
WARN Affinity - Windows JNA-based affinity not usable because it
failed to load! Reason: java.lang.NoClassDefFoundError:
com/sun/jna/platform/win32/WinDef$DWORD
and the execution is not bound to the single core.
I'm blindly trying to give the software what it wants without understanding what it needs.
i suspect youve added jna.jar, but not jna-platform.jar to your project, and the class that fails to load ispart of platform.
see docs and download links here.
