Coldfusion having trouble while loading classes in Jar file

Hi everybody.
I have some weird problem with Coldfusion.
I try to use a Jar file, that i put in the Coldfusion classpath. It works well (i can call some classes in the Jar file using the createObject() function ), but not every classes.
For example,
<cfset ServiceObject = createObject("java", "com.google.api.ads.dfp.v201204.NetworkServiceInterface")>
<cfdump var="#ServiceObject#">
this call works well, and i can the see the dump file.
<cfset dfpServiceObject2 = createObject("java", "com.google.api.ads.dfp.v201204.NetworkServiceSoapBindingStub")>
<cfdump var="#ServiceObject2#">
This call fails, and i got a 500 error :
ROOT CAUSE:
java.lang.NoClassDefFoundError: Could not initialize class com.google.api.ads.dfp.v201204.NetworkServiceSoapBindingStub
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java: 39)
at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorIm pl.java:27)

at java.lang.Class.newInstance0(Class.java:355)
at java.lang.Class.newInstance(Class.java:308)
at coldfusion.runtime.java.JavaProxy.createObjectWithDefaultConstructor(JavaProxy.java:191)
If i check in the Jar file, i can see the NetworkServiceSoapBindingStub class. Moreover, when i do the same thing directly in a java application, it works well. Nevertheless, Coldfusion is not able to load this class. How can this be possible? Do you have any idea to help me?

I have not been able to resolve this to date. Does anyone have half a clue as to what I might be doing wrong?

Errors generated while loading classes in jar file

Hello all,
I am attempting to install the xml parser using the loadjava utility. Here is my commandline call:
loadjava -user user/password -r -v xmlparserv2.jar
where user and password are the appropriate.
I made sure my CLASSPATH was not set to anything.
When I run this against Oracle 8.1.5 I get the following for quite a few of the classes in the JAR file.
resolving: oracle/xml/parser/v2/XMLExternalReader
Errors in oracle/xml/parser/v2/XMLExternalReader:
ORA-29534: referenced object XCOM.oracle/xml/parser/v2/XMLNode could not be resolved
ORA-29545: badly formed class: java.lang.NullPointerException
Some the classes compile without problems, but the majority report this error. Also it takes some time to compile and reach this conclusion.
On my first run loadjava reported 227 errors.
What am I doing wrong. Any and all feedback would be highly appreciated.
Thanks,
Bediako George

How to load class from jar file dynamically?

After I run my Java applicatoin, I need configuring the classpath of jvm to load some classess inside a jar file into the same jvm.How can I achive that?
I mean, when I run my Java application, I don't know where the jar file is, what the jar file name is. All depends on the user to tell the jvm the details through some UI. I've tried to write: System.setProperty("java.class.path", "c:\myClass.jar");Class.forName("MyClass"); but failed.
Can you tell my why and how?
Thx

Can you tell my why and how?The usual way is to use a custom classloader.
You can start by looking at java.net.URLClassLoader.

i used it and run the program it run okay but when i try to open the jar i hear no sound????????????
I Don't know whyyyyyyyyy This seems to indicate that your app is finding the mp3 file. You would probably get a null pointer exception if the file wasn't found. Something else seems to be going on.
-How are you launching the jar outside of NetBeans?...By Double Click On It
I suggest trying to launch the jar using the command promptjava -cp YourJarFile.jar YourMainClassAnd if that works, try java -jar YourJarFile.jarAnd if that works, your computer's file association is not set up correctly.

Unable to load classes from jar files inside APP-INF/lib in EAR.

Weblogic version: 10.3.3
Platform: Linux x86-64 bit
We deployed an ear packaged with all the common library jars inside APP-INF/lib. Deployment was successful.
for some reason, it is always giving ClassNotFoundException for the classes inside the jars. This does not happen
in 10.3.2 version of weblogic.
We tried to add them to domain/lib directory (instead of APP-INF/lib) but still it is not able to resolve the classes.
Any pointers would be appreciated.

try using prefer-web-inf-classes in the weblogic.xml file in your WAR file
or using prefer-application-packages in the weblogic-application.xml file in your EAR.

IO Error while deploying application client jar file ???????

Hi,
In my .ear file, one application-client jar(which contains all helper classes which are used in whole application) file is there. While deploying .ear file, all ejb are getting deployed well, while deploying application client jar file(Global.jar file here) it is giving the following message:

Please let me know Why i am getting 'IO Error' , where i may done wrong ?
Thanks in Advance
Srinivas

Srinivas,
Before we continue, PLEASE tell me if you've looked through the available
documentation, code samples, "how-to" documents, etc., for OC4J. It
seems to me that you're mixing things up a bit. I use the "deploy"
command to deploy my EARs, example (partial):
java -jar admin.jar ormi://<host> admin <password> -deploy ...
And my EAR file is not in the "application-deployments" directory
when I issue that command.
Perhaps you could also show me the contents of your "application.xml"
file for this application you are having trouble with.
But I repeat, please tell me if you have already looked at the
available documents regarding OC4J!
Thanks,
Avi.

How to load an applet jar file?

Hello everyone,
I have an applet that uses my own jar file and approximately 6 third party jar files. I set up jar indexing (jar -i) which will download the jar files when they are needed. All seems to work well, but now I want to manually load the jar files which I cannot get working.
When the applet starts, about 1/2 of the jar files are downloaded (because they are needed at startup). I then want to load the additional jar files in the background, after the gui is initialized. I have tried this using the below thread which is executed from within the applet's start method:
// Try to load additional jar files in background by loading a class from each jar file.
Thread loadClass = new Thread() {
public void run() {
    System.out.println("Loading classes...");
    try {
      // Tried loading classes this way, doesn't work.
      getClass().getClassLoader().loadClass("pkg1.Class1");
      getClass().getClassLoader().loadClass("pkg2.Class2");
      getClass().getClassLoader().loadClass("pkg3.Class4");
      getClass().getClassLoader().loadClass("pkg4.Class4");
      /* Loading classes this way doesn't work either.
      Class.forName("pkg1.Class1");
      Class.forName("pkg2.Class2");
      Class.forName("pkg3.Class3");
      Class.forName("pkg4.Class4");
    catch(ClassNotFoundException e) {
      // First attempt to load a class (pkg1.Class1) throws exception.
      System.out.println("Can't find class: " + e.getMessage());
loadClass.start();As you can see from above I am trying to load a class from each of the jar files so that the jar files would load into memory/cache. Unfortunately, it cannot find the classes. These are the errors from the java console:
Loading classes...
Loading: pkg1.Class1
Connecting http://my.server.com/my_dir/pkg1/Class1.class with no proxy
Connecting http://my.server.com/my_dir/pkg1/Class1.class with cookie "JSESSIONID=some_big_long_char_list"
Can't find class: pkg1.Class1
So it appears the jar file is not being downloaded. When I take away the dynamic jar loading (removing the "jar -i" & adding them all to the applet archive list) the thread executes correctly. So I know the class names, etc, are correct. How does one load an applet jar file?
Any help/suggestions are appreciated.

The above error I posted was because I forgot to index the jar files. That is why it couldn't find the jar file. I thought I was getting farther along with my problem, but I apparently just forgot to index the jars. I am now getting the problem that I got yesterday...
The applet freezes/hangs when it hits the thread. The GUI never opens (even though I'm running this thread right after the gui shows). The java console quits responding and the applet just stays the grey screen. I also tried the invoke later that you suggested.
public void start() {
// ...initialize gui...
// Applet freezes and remains grey, also the java console freezes.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
    public void run() {
      System.out.println("Loading classes...");
      try {
        // When I comment out the below forName calls, the thread will still run evidenced through the done print statement.
        Class.forName("pkg1.Class1");
     Class.forName("pkg2.Class2");
     Class.forName("pkg3.Class3");
     Class.forName("pkg4.Class4");
        System.out.println("...Done loading classes");
      catch(Exception e)     {
        System.out.println("Can't find class: " + e.getMessage());
}

What is it supposed to do with your request to use 256m of memory for heap
when you are not giving it a class or a jar to run?

Loading library from jar file

Hi all,
My question is can we load library from jar file using System.load() method.
ex:
myJar.jar
|
|----com.test.common.Util
which conatins a method to load library from jar file itself, before that i used to load from File
|---libraries/MozillaParser/......
Iam able load from Local system,
File parserLibraryFile = new File("libraries/MozillaParser" + EnviromentController.getSharedLibraryExtension());
File mozillaDistBinDirectory = new File("libraries/mozilla.dist.bin."+EnviromentController.getOperatingSystemName());
MozillaParser.init(parserLibraryFile.getAbsolutePath() , mozillaDistBinDirectory.getAbsolutePath());
but i am unable to load from jar file
URL url = ClassLoader.getSystemClassLoader().getResource("libraries/MozillaParser" + EnviromentController.getSharedLibraryExtension());
URL url1 = ClassLoader.getSystemClassLoader().getResource("libraries/mozilla.dist.bin."+EnviromentController.getOperatingSystemName());
MozillaParser.init(url.toString(), url1.toString());
Thanks in advance.

That's a really confusing post.
The easiest way to make sure you can use the classes in a jar file is to copy the jar file to the "/jre/lib/ext" subfolder of your JDK. These classes will be visible to all applications.
