ClassNotFoundException
We are developing a download client.
There HTTP_Class implements ProtocolWrapper interface.ProtocolWrapperMapping maps into correct protocol class.
ProtocolWrapperMapping & ProtocolWrapper interface is inside another subpackage.HTTP_Class implementation along with its properties is inside another package.
When ProtocolWrapperMapping.init() is called, HTTP_Class should be loaded(which is in another package).but error comes as below.
java.lang.ClassNotFoundException: HTTP_Class
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at GetLeft.core.downloadmanager.ProtocolWrapperMapping.init(ProtocolWrapperMapping.java:63)
at GetLeft.GetLeftMain.main(GetLeftMain.java:156)
we tried to import too but in vain.
Plz give me a solution.Its very urgent.
Thank you

Sounds like a classpath error, if the HTTP_Class class is in a jar file, include that jar file in the classpath.

Exception in thread "main" java.lang.ClassNotFoundException: oracle.jdbc.dr
Hi
I am trying to use type 4 driver to connect to my Oracle 9i Rel2 database. I downloaded the odbc14.jar from oracle and added in the C:\Oracle9i\jdbc\lib path. As on the website, I setup my environment:
Setting Up Your Environment
On Win95/Win98/NT:
- Add [ORACLE_HOME]\jdbc\lib\classes111.zip and
[ORACLE_HOME]\jdbc\lib\nls_charset11.zip to your CLASSPATH.
(Add classes12.zip and nls_charset12.zip if JDK 1.2.x or 1.3 is
used. Add ojdbc14.jar and nls_charset12.zip if JDK 1.4 is used.)
- Make sure [ORACLE_HOME]\bin is in your PATH.
Still I am getting the following error during runtime:

Next-generation plug-in 1.6 : ClassNotFoundException and not caching JARs
Hi,
Since the introduction of the next-generation plug-in in Java 1.6.0_10, the applet I have used and developed for many years don't load anymore.
The situation is this : the Jars of this applet are embedded in a Lotus Notes database as Java resources, in order to be used in a particular form in my application. Note that this application is accessed via a Web browser through a Domino server and that this application requires a user authentication. If I try to open the form containing the applet while using a plug-in 1.6.0_10 or newer, with default parameters (cache and next-generation plug-in activated), here is the exceptions I get (here with plug-in 1.6.0_20) :
load : class mycompany/tools/Planner not found.

Exception : java.lang.ClassNotFoundException: mycompany.tools.PlannerBy reading a lot forums I found that a lot (really a lot) of people were experiencing the exact same issue, regardless of the type of server they used to host their applet. And unfortunately, only few answers were relevant to help me understand why I got this error...
By looking deeper in the documentation, I have found this [Applet Developer's guide|http://download.oracle.com/javase/6/docs/technotes/guides/jweb/applet/applet_dev_guide.html]. Here, it is written that one of the enhancement of the next-generation plug-in is that : "+... The JVM running the applet is isolated from the web browser at the operating system level. If something should go wrong while running the applet, or if an uncooperative applet refuses to shut down, the new Java Plug-in detects and handles the error condition gracefully; the Web browser is unaffected+".
I am not quite sure of what it really means, but I have started to think that my problem could be that, by running in a separate process than the one of the Web browser, loading the Jars will require an authentication on my server. To verify this hypothesis, I have changed the codebase of my applet, so the Jars are downloaded from another server where no user authentication is required. The good news is that my applet can now find the Jars and run as expected. The bad news is that none of the Jars are placed in the cache, which means that the Jars have to be downloaded each time I start a new session to work with my applet.
I have also tried to disable the "Use the next-generation plug-in" option in the Java control panel. In this case, everything is fine, too, and even the Jars are stored in the cache. The interesting thing is that afterwards, by enabling the "Use the next-generation plug-in" option again, the applet will load and run like a charm... because the Jars are in the cache and the class loader can find them! (I suspect that this case has been experienced by several people, answering on forum posts that they cannot reproduce the issue.)
Anyway, even if there is some workarounds to ensure it is possible to work with the latest versions of the plug-in, having to change the default options is not always easy or possible, depending of the environment. This applet that I am talking about is used by a lot of our customers and all have their internal policies and requirements regarding the Java configuration. If for some of them it will be possible to use a workaround, for others it will not. And this is a major problem to me.
As I said, a lot of people have experienced this issue. I hope that someone having a better understanding on how this next-generation plug-in works, will have a solution, or at least, will be able to explain what is wrong in this approach and if my suggestion regarding an authentication issue for the class loader make sense.
Any help will be greatly appreciated.
PhilippeHi,
I was wrong in my approach.
My applet was implemented using the "<object>" tag and it seems that it was not the best way to address compatibility issues across all versions of the plug-in and all browsers.
So, I have finally found what I was looking for in this "[Java Rich Internet Applications Development and Deployment|http://download.oracle.com/javase/6/docs/technotes/guides/jweb/index.html]" guide. In this guide, it is recommended to use the "[Deployment Toolkit|http://download.oracle.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit]", based on a Javascript library containing everything needed to deploy your application as an applet or a Java Web Start application.
My application, deployed as an applet, now works like a charm.
I hope pointing on this Deployment Toolkit will also help others...

ClassNotFoundException for a single class in my project... HELP!
Hey all,
I hope someone has an answer to my problem because I wasted enough time trying to figure it myself and, admittedly, I have no idea what I'm doing.
So I have two projects in Eclipse. One project contains a bunch of data access objects (DAO) -- my data access layer -- and the other project is a tool which uses the DAOs to perform some operations. So everything was going hunky-dory until I made an instance of this one DAO class in my tool. When I tried running it, I got a ClassNotFoundException being thrown from the constructor invocation (i.e., new DAO()). It didn't execute the constructor, it just went straight into the exception code. This makes no sense to me because every other DAO class I'm using in my tool works just fine.
I've tried cleaning my projects out and rebuilding to no avail. I've also deleted them from my workspace and checked them out from my CVS server, again to no avail. Does anyone know why this one DAO is not visible to my tool?! Why it can't find it?!
I'm willing to try anyone's suggestion at this point, so please help! I'd appreciate it. Thanks!This makes no sense to meWhat you are dealing with here is a classpath issue. At compile time, apparently whatever DAO class you need is available and the compiler has nothing to complain. When the application is executed however, the DAO class is no longer in the classpath.
So how is your DAO project built? If it is a jar (if it is not, it should be), then that jar is not in the classpath of your tool while it is being executed. Most likely you need to add the jar as a library to the project of your tool for it to work. -

Please help. ive been working on it for days =(.If you're running a Web app, put all JARs that your app needs in the WEB-INF/lib directory. That's always in the CLASSPATH.
I don't know WebSphere. Do you really have to edit something to add all those CLASSPATH entries?
In Tomcat, all I'd have to do is put a WAR file in the webapps directory.
Your code needs some work. You're not following Sun's Java coding standards. Capitalize your class name, for starters.
Is the username and password for your database still "scott" and "tiger"? Nice security there.
Your connect method makes a database connection. Do you leave it to users to close it? (You do close your connections when you're done with them, don't you?)
I'd make Connection a data member and create it in a constructor. I'd write a close method to close it up.
Doesn't WebSphere do connection pooling? Do you really want to write your own class to handle this?

The class file its complaining about AddUserxRolePars exists in FoxTWS.jar (generated from wsimport) in ThirdParty, ext and JavaTasks directory on the server and still it complains for the same.
I tried running the same class from the command prompt on the same server and it's working fine. Thinking this could be classpath issue, I tried updating the classpath (System.setProperty("java.class.path","<jar file path>+<existing classpath>")) from with in the adapter class file and it still does not help.
Any thoughts on how to resolve this ??
Thanks in Advance.You can use below policy for 2-way SSL
Wssp1.2-Https-ClientCertReq.xml
Two way SSL. The recipient checks for the initiator's public certificate. Note that the client certificate can be used for authentication.
http://docs.oracle.com/cd/E14571_01/web.1111/e13713/message.htm#i243732
Please follow below link to invoke standalone client using SSLSocketFactory for 2-way SSL

Done.
in my form i have created a bean_area and used as implementation class :ApiConn
in my formsweb.cfg i used this configuration: archive=frmall.jar,siberia_jpg.jar,ApiConn.jar,Hasher.jar,ReadCommand.jar,WriteCommand.jar,libAPI.jar
in my forms/java i have placed my jar files listed in the frmall.jar
i guess i am missing something but i dont know what it is.
here is my ApiConn.java from wich i generate my jar file:

Every time I try to run a java program: Java.lang.ClassNotFoundException?
I downloaded the JDK version 6 successfully for my laptop which runs windows 7 (64bit). I'm trying to run programs that I have successfully run at school on my computer put it doesn't work. I pull up the command prompt and enter javac "program name".java and it compiles fine. Then, when I type java "program name" it gives me the Java.lang.ClassNotFoundException. Can anyone please help me??
Try:

My web page uses a Java Applet to allow my visitors to replay chess games; the Chess Viewer Deluxe applet was written by Nikolai Pilafov some time ago and has been working properly for some time (until recently). I don't monitor this part of my site regularly so I am not sure when it began to fail. On his web site [http://chesstuff.blogspot.com/2008/11/chess-viewer-deluxe.html] he has a link to check LiveConnect object functionality (which fails for OBJECT tags). His recommendation is to "seek platform specific support which might be available from the JRE developers for your platform".
I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Until I checked the LiveConnect object functionality, I was unable to identify the source of the console error messages. This does seem to be the smoking gun.
Is Apple aware of this problem? Are these classes no longer supported? Has anyone else had this problem? You can attempt to recreate the problem locally by going to my web page: http://donsmallidge.com/DonSmallidgeChess.html
Thanks in advance for any help you can provide!

Windows Vista "java.lang.ClassNotFoundException: loader.class" error.
Hello,
Whenever I try to visit websites that have a java applet I get a dialogue with the following error:
java.lang.ClassNotFoundException: loader.class.
I have tried uninstalling/reinstalling java, and also adding the -xmx and -xms parameters for java applet runtime setting in control panel with various values from 128m to 1g.
The applet at http://www.java.com/en/download/installed.jsp?detect=jre&try=1 does work and reports "CONGRATULATIONS, you have the Latest version of Java!", "Java Runtime Version 1.6.0."
I have been experiencing this problem ever since I installed Windows Vista Home Premium a day or two ago. Any help is appreciated.

The jar file is in the user_projects/domains/mydomain/lib directory.
Attaching the policy to BPEL services has no issue and the policy is invoked successfully.
I am unable to determine why the OSB would behave differently in this regard, or what I need to configure differently in order to have it found by the class loaders for the OSB.
Any help or suggestions appreciated.
I am using 11.1.1.4.0
The jar file has the necessary policy_config.xml file and the META-INF/mylabel/mypolicy.xml files in situ. As I said, it is working in the soa_server but not the OSB.Have you restarted servers after putting jar in $Domain_Home/lib directory? Also try after explicitly adding this jar in classpath by editing server startup script (startManagedWeblogic.cmd or .sh) or in domain env setting script (setDonainEnv.cmd or .sh) and restarting the servers.
Regards,
Anuj

WebLogic 10.3.5 ClassNotFoundException (jar file is available in classpath)
Hi, I'm facing a problem on WLS10.3.5 + Spring 3.1 + Hibernate 3.6.7 connecting to Apache Derby 10.8.1.2.
The Spring ContextLoaderListener configured in the web.xml is failing since the the entityManagerFactory creation failed - since the derby datasource defined in WLS could not be created. Root cause - ClassNotFoundException by the weblogic.utils.classloaders.GenericClassLoader. I've tried adding derbyclient.jar in all locations - WLS server lib, domain lib, WEB-INF/lib, VM_HOME/jre/lib/ext, and also tried setting PRE_CLASSPATH. Also tried keeping a duplicate copy of the jar in all the locations at the same time. No luck.
Caused By: java.lang.ClassNotFoundException: org.apache.derby.client.am.ConnectionCallbackInterface
at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(GenericClassLoader.java:297)
at weblogic.utils.classloaders.GenericClassLoader.findClass(GenericClassLoader.java:270)

at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
at weblogic.utils.classloaders.GenericClassLoader.loadClass(GenericClassLoader.java:179)
Truncated. see log file for complete stacktrace
The datasource is created successfully from the console so there's no problem with the jar file. I could also load the above class using a test JSP from another bare WAR deployed into the same domain.
I'm out of ideas and need some options to explore. btw, I specified in the weblogic.xml that the antlr.* classes should be taken from the application. Also tried this option for org.apache.derby.* classes.
This looks like a buggy class loader problem. Any ideas or solution please?"The datasource is created successfully from the console so there's no problem with the jar file."
Did you also test the data source when you created it?
- when yes then WebLogic can indeed find the derbyclient.jar as the driver org.apache.derby.jdbc.ClientDriver is part of it.
"I specified in the weblogic.xml that the antlr.* classes should be taken from the application. Also tried this option for org.apache.derby.* classes."
Have you only defined a
<prefer-application-packages>
<package-name>antlr.*</package-name>
<package-name>org.apache.derby.*</package-name>
</prefer-application-packages>in weblogic.xml or did you also turn on prefer-web-inf-classes?
It is smart to start from scratch and delete all the jar files in all the directories. To make the derbyclient.jar part of the WebLogic classpath you can do the following:
- edit setDomainEnv: When you open setDomainEnv there is an entry like "SET THE CLASSPATH". Just before - if [ "${JAVA_VENDOR}" != "BEA" ] ; then
you can put something like: CLASSPATH=${CLASSPATH}${CLASSPATHSEP}location/derbyclient.jar
If the class must be available on every server in a cluster, you can edit the commEnv file (located in the ${WL_HOME}/common/bin directory)
Search for the entry "set up WebLogic Server's class path". And below the WEBLOGIC_CLASSPATH you can add something like:
WEBLOGIC_CLASSPATH=${WEBLOGIC_CLASSPATH}${CLASSPATHSEP}location/derbyclient.jar
Hope this helps you a little -
ClassNotFoundException in EJB's and Threads (Classloader issue)
A very interesting bug has cropped up in WebLogic 6.1. When a J2EE
application packaged appropriately, a client application running in a
user-created Thread will always throw a ClassNotFoundException when
attempting to get back a user-created object from an EJB living on
another cluster. This error does not happen when the call is being made
from outside a Thread.
Sounds strange, I know, so I'll try to give everyone as much detail as
possible so they can avoid this bug, and so that the folks at BEA can
fix it.
* A java class running inside a clustered WL6.1 server is attempting to
reference an EJB on another clustered WL 6.1 server. Accessing the bean
is not a problem, the client class is able to obtain a remote reference
to the bean and make method calls on it. Calling a method causes the
following stack trace:

* The class that is not found (JobsData) is definitely in the EAR file
on both the client cluster and the server cluster, and in the
appropriate location.
* When we attempted to run the code outside of a Thread, everything
worked perfectly, so it was definitely the Thread that was causing the
problem.
* Deploying the EJB on the client cluster did not do anything to solve
the problem.
* Adding the JobsData to the System CLASSPATH at the startup of the
WebLogic server DID solve the problem. But of course that defeats the
purpose of packaging everything in the EAR file.
So, the conclusion seems to be that when DisplayJobs$JobsMonitor kicked
off the Thread, the Thread should have been created in either the WAR's
classloader or the JAR's classloader (wouldn't matter, since the
JobsData class is in the JAR's classloader, which is a parent of the
WAR's classloader). But instead, the Thread is being created in the
System classloader, which can't find the JobsData class!
We believe that any Thread created by a class living within an EAR's
classloader should remain within that same classloader, and not migrate
to any other classloader, in order to avoid situations like this. We're
opening a case with BEA to attempt to get this resolved. In the
meantime, we recommend to developers that if they have to make
cross-cluster RMI calls from inside user-created Threads, that they only
attempt to receive primitive types or standard JDK objects. Otherwise,
you'll have to add the classes to the System CLASSPATH at startup of the
WebLogic instance.

* The class that is not found (JobsData) is definitely in the EAR file
on both the client cluster and the server cluster, and in the
appropriate location.
* When we attempted to run the code outside of a Thread, everything
worked perfectly, so it was definitely the Thread that was causing the
problem.
* Deploying the EJB on the client cluster did not do anything to solve
the problem.
* Adding the JobsData to the System CLASSPATH at the startup of the
WebLogic server DID solve the problem. But of course that defeats the
purpose of packaging everything in the EAR file.
So, the conclusion seems to be that when DisplayJobs$JobsMonitor kicked
off the Thread, the Thread should have been created in either the WAR's
classloader or the JAR's classloader (wouldn't matter, since the
JobsData class is in the JAR's classloader, which is a parent of the
WAR's classloader). But instead, the Thread is being created in the
System classloader, which can't find the JobsData class!
We believe that any Thread created by a class living within an EAR's
classloader should remain within that same classloader, and not migrate
to any other classloader, in order to avoid situations like this. We're
opening a case with BEA to attempt to get this resolved. In the
meantime, we recommend to developers that if they have to make
cross-cluster RMI calls from inside user-created Threads, that they only
attempt to receive primitive types or standard JDK objects. Otherwise,
you'll have to add the classes to the System CLASSPATH at startup of the
WebLogic instance.
Thanks,
Erin
