Loadjava - exception class not found

Hi, I'm running Oracle 8.1.2.0 on HP UX and I've started to look at Java and Oracle. I created a sample class and when I try to load it in the database it gives me the following error:
Class not found: oracle.aurora.server.tools.LoadJavaMain
I've searched thru Technet and it says something about a aurora_tools.jar in lib dir, but I've searched my entire hd and didn't find it.
Is there anything wrong with my instalation, or my version doesn't have that file?
I have 8.1.6 in CD if I install it, it solves my problem? Please help...
Eduardo

Errors with CF 8.0.1 hotfix 3 and hotfix 4, "Object Instantiation Exception.Class not found"

We need to get our servers up to date with the latest ColdFusion hotfixes in order to pass our security scans and policies. We have been following the Adobe instructions for installing the hotfixes, but we’re getting the same errors each time. The CF 8 hotfix 2 works fine, but once we install hotfix 3 and/or hotfix 4, we get the following errors:
"Object Instantiation Exception.Class not found: coldfusion.security.ESAPIUtils The specific sequence of files included or processed is: C:\ColdFusion\wwwroot\WEB-INF\exception\java\lang\Exception.cfm, line: 12 "
coldfusion.runtime.java.JavaObjectClassNotFoundException:
We have dozens of servers running Windows XP, Netscape Enterprise Server 6.1 (I know, don’t laugh), ColdFusion 8,0,1,195765, and Java Version 1.6.0_04. Just about the only good thing about running XP on our servers is that it matches our development boxes, so we have almost mirrored environments for dev, test, and production. We do NOT have the CF install with the J2EE configuration.
The crazy thing is, on tech note 51180 (http://kb2.adobe.com/cps/511/cpsid_51180.html), it says that the fix for bug # 71787 (Fix for "Object Instantiation Exception" thrown when calling a Java object constructor or method with a null argument under JDK 1.6.) was added in cumulative hotfix 2. However we don’t see this problem until we go to hotfix 3 (or 4).
I’ve also been reading that other people had this same problem, and that the CF 8 hotfix 3 was not compatible with certain versions of JDK, then when you read the Adobe site for CF 8.0.1 hotfix 3, it says “Added the updated cumulative hotfix to make it compatible with jdk 1.4.x, 1.5.x and 1.6.x.”, so that makes me think that Adobe was supposed to have fixed this CF 8.0.1 hotfix 3 JDK incompatability issue - but unfortunately it's still not working for us. We have followed the instructions for removing the jar files and starting/restarting the CF server as directed, we’ve tried this 5-6 times, and still no luck.
Recommendations? Seems like this is a ColdFusion bug to me – one that says is fixed on the Adobe site, but is not fixed in our environment. Please advise, thanks.

For what it's worth, we had an MXUnit user describe a similar, though not identical, problem after installing the latest hotfixes. In his case, he's getting "NoSuchMethodExceptions".

Class not found error on Firefox browser

Requirement:-
We have Apache server on the top of a tomcat container where we have deployed application Webnow. This application will provide SSO to another application Imagenow. The requirement is we have to authenticate and authorize a user based on the client certificate which will be installed on the client side browser.
Issue:-
We have achieved the requirement for the browser IE. But for browser Firefox ,we are getting an exception "Class not found". Basically an applet class from the jar is not getting loaded on the Firefox.
Further investigating on this we came to conclusion that Firefox is not able to read the SSL certificate.
In order to eliminate this, we have imported the client certificate in java console as well. After this step, we were not getting "ClassNotFoundException" in FF. But right now, user is getting prompted for certificate/keystore password each & every time while trying to login onto the application (both in IE & FF).
So, we are trying to find ways to remove class not found exception without importing client certificate to java console. Also , is there any way to eliminate the authentication pop up for keystore (though we might not go for this approach as it will be very difficult to manage Java console for end users). Need your urgent help on this issue.
Attaching stack trace of both the browser and screenshot of keystore authentication pop-up . FF_Issue_stacktrace.docx is one when we were getting "class not found exception" and IE_Stacktrace.docx is one for successful case.

We have a similar set up where we have a web app and an applet in a JSP page. You have to put your applet classes up above WEB-INF. So, if your structure for your webapp was:
tomcat/webapps/mywebapp
you'd want your classes under mywebapp instead of webapps/mywebapp/WEB-INF. In your case, if I read your package structure right, you'd want a Log directory under webapp that contains your LogApplet.class file.
I hope this works for you!

Not able to start the remote server - class not found exception

All,
I am quite new to RMI programming, although i am an experienced java programmer. I am facing a problem in starting the remote server program which i wrote for RMI. I am getting class not found exception for "stub" class eventhough the class is in the classpath.
Following is the error console:

Following are my classes:
MyRemoteInterface.java
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyRemoteInterface extends Remote {
public String[] getNames() throws RemoteException;
public class MyServerImplementation extends UnicastRemoteObject implements
MyRemoteInterface {

super();
public String[] getNames() throws RemoteException{
return new String[]{"Name1","Name2","Name3","Name4"};
public static void main(String args[]) {
try {
// Create an object of the HelloWorldServer class.
MyRemoteInterface obj = new MyServerImplementation();
// Bind this object instance to the name "HelloServer".
Naming.rebind("rmi://localhost:1985/GetNames", obj);
System.out.println("GetNames bound in registry");
catch (Exception e) {
System.out.println("GetNames error: " + e.getMessage());
e.printStackTrace();
public class MyRMIClient {
*@param args*
public static void main(String[] args) {
try {
MyRemoteInterface remObj = (MyRemoteInterface) Naming.lookup("rmi://localhost:1985/GetNames");
System.out.println("Names are "+remObj.getNames());
catch(Exception e) {
System.out.println("Problem encountered accessing remote object "+e);
}

That's a remote exception coming from the registry. You need to learn to recognize remote exceptions and their source, it's a mjaor source of confusion in RMI.
In this case it's the registry that can't find the stub class.
The stub class needs to be in the CLASSPATH of (i) the Registry and (ii) the client as well. Ditto the remote interface; ditto any application classes it refers to, and so on until closure.
The easiest way to achieve (i) is to start it in the server's JVM, with LocateRegistry.createRegistry().

Class not found exception XMLGregorianCalendarImpl* in PI 7.0

Hello Experts,
I have written java Class where used the following package and Class in PI 7.1and it is working fine
import com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl;
//part of the Java Class code
XMLGregorianCalendarImpl XMLGenTime = new XMLGregorianCalendarImpl(gentime);
XMLGregorianCalendarImpl XMLExpTime = new XMLGregorianCalendarImpl(exptime);
but when I am trying to use the same Class XMLGregorianCalendarImpl in PI 7.0 I I am getting the runtime exception.
<Trace level="1" type="T">Class not found:
com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImp

if I write a seperate UDF for the below code and use the jar file jaxp-ri-1.4.1.jar in PI 7.0 ,
long TicketTime=3600000;
          String LoginTicketRequest_xml=null;
             Date GenTime = new Date();
          GregorianCalendar gentime = new GregorianCalendar();
          GregorianCalendar exptime = new GregorianCalendar();

XMLGregorianCalendarImpl XMLGenTime = new XMLGregorianCalendarImpl(gentime);
Kindly help me to solve this problem.
Thanks,
Kubra

I have found the solution.
The problem is solved by adding jaxp_api_1.3 jar and jaxp-ri-1.4.1.jar.we have to have both these jar in PI 7.0 to use com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl package
Thanks

Class Not Found Exception - applet won't run anywhere outside of IDE

I have an applet that runs perfectly in the netbeans IDE, but won't run from command prompt (I'm using windows) or from a browser. I've been banging my head against the wall for a few days on this one. Here's the HTML I'm using:
<applet width="400" height="525" code="musicapplet.class" archive="crypticgraffiti.jar">
<param name="bgcolor" value="ffffff"> <param name="fontcolor" value="000000">
</param> </param> Your browser is not Java enabled. </applet>
Here is the structure of the jar file's contents:
META-INF/
META-INF/MANIFEST.MF
com/
com/crypticgraffiti/
com/crypticgraffiti/music/musicapplet
com/crypticgraffiti/music/GetNotes.class
com/crypticgraffiti/music/InstList.class

com/crypticgraffiti/music/MusicCreator.class
com/crypticgraffiti/music/OctaveTransformer.class
com/crypticgraffiti/music/Phrase.class
musicapplet/MusicApplet$playerThread.class
musicapplet/MusicApplet.class
(Musicapplet.class is the main class)
When I attempt to run from command prompt, I get:
"Error: Could not find or load main class crypticgraffiti.MusicApplet"
When I attempt to load via html:
"basic: load: class musicapplet.class not found.
load: class musicapplet.class not found.
java.lang.ClassNotFoundException: musicapplet.class
     at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)

I have tried every possible variation for the 'code' element of the applet tag (package.mainclass.class, mainclass, mainclass.class, etc). I have also tried compiling with JDK 1.6 and this didn't change anything. I've tried clearing out the cache of temporary files using the java control panel settings, and have verified that my browser can run other applets using JRE 6 and 7.
I've tried some different ways of distributing the applet, also: putting all the class files in the folder with the html file, putting the classes in a source folder in the same folder as the html file, and finally putting a jar in the same folder as the html file (which really seems the simplest).
Any help at all would be most appreciated! This applet is a very cool and original music creating app that draws heavily on the JFugue API. It's a shame that I can't get it online for people to play with!

Please note that class names are case sensitive so "MusicApplet" is not same as "Musicapplet" or "musicapplet". Your applet tag should have fully qualified class name (without quotes) and should look like this:

</applet>
The JAR should be in the same directory as your HTML file. While launching from command line, you can also check if your JAR file is getting included in classpath.

Hi Mark,
I have seen your two posts and there are something you need to notice:
Where the ClassNotFound exception you got? From deployment tool or
application server kjs process?
Of course, you need not to add supporting classes to each ejb jars or ears.
1. If you use deployment tool to package your application, I'm sure you'll
fail to resovle your classes without supporting classes added to jars.
Please select Edit->Preference,in Classpath entry, enter the supporting
classes(packaged to jar files) location. This should work.
2. After deploy to ias, please edit the registry using kregedit which you
described in your posts.
Regards,
Johnson

When I deploy EJBs to the iPlanet app server I find that I need to include
all supporting classes in each ejb jar file. According to the
Administrator's manual I should be able to modify the kjs classpath bydoing
the following:
On Windows
a.. Open iPlanet Registry Editor.
(See About iPlanet Registry Editor)
b.. Open the following key:
SOFTWARE\iPlanet\Application Server\6.0\Java\
c.. Modify the class path and restart the server for the change to take
effect.
However, when I add my supporting classes to a jar in this directory Istill
get a class not found exception when I run the deployment tool.
Adding the classes to each EJB jar is redundant and introduces lots of
problems. How should I configure iPlanet so I only need to put my
supporting classes in one place?
Thanks,

The JDeveloper IDE raise the Exception From the invoking the BPEL process through the java code .Class Not Found Exception (Locator,ID.......).What is process of importing these classes from API.

Sunil,
Administration-- Callout Details -- Implementation Class -- XXClassFileNameMake sure that you are giving complete name of the class (without extension .class.). For an example if your class name is Sample and it is in package a.b.c then give class name as a.b.c.Sample
Administration-- Configuration -- Callout Directory -- xx/yy/zz (UNIX server that is accesible from B2B)This must be valid directory existing on machine where B2B is installed.
2.Partners--XX--Delivery Channel -- Select the channel where we need the call out -- Channel Attributes -- Transport Callout -- XXJavaCallout
3.Agreement--Callout -- XXJavaCalloutTransport Callout and Agreement Callouts are used for different purpose. Are you sure that you really need both in your case?

Java applet class not found exception for check scan

I am getting a class not found exception when trying to scan a check into a banking website. The application uses Java and the exception error has the name "com.epaysol.checkscanAppletV2" in the message. I have the latest Firefox and the latest Java installed.

Error : class not found exception : com.mysql.jdbc.driver in Eclipse Tool

Hi
I have impoted project file in eclipse in new machine using option import from existing workbence . When i stat to debug this project ,
i am getting error as class not found exception : com.mysql.jdbc.driver . my project folder already consist of mysql .jar file in /web appls/web-inf folder.
Application is running successfully in other machine from where i took the application file. As this error appeared I also added jar file into project path as Project ---->properties-- build java path---libraries----add external jar file.
kindly hep me.

Sounds like an eclipse question - not a JDBC one.
But since eclipse is telling you it can't find it then it means it is not in the eclipse path. So you must add it. (The fact that it is somewhere is irrelevant - all that matters is it is not in the class path.)

Class Not Found Exception After Connecting From a JDeveloper

Hi,
I am following the tutorial on SOA and started to experience problems in deployments (all but the console, including em) after the connection to the remote weblogic (10.3.5) from JDeveloper. I would know if the connection modifies the WLS environment. Unfortunately I did not note the message before wiping the setup, but found many entries on Google referring to some ADF library. I followed the suggestion to apply the adf runtime to the WLS install but this not helped.
By the way, I would just understand if the remote connection from a JDeveloper adds some configuration which is then eventually not found in the target WLS.
Thanks

Can you check the log files of soa_server1, which are located in the <domain-home>/servers/<server-name>/logs.
There are probably some occurences of class not found exceptions.
When you are using the node manager to start your environment you have to make sure that StartScriptEnabled is set
to true in the nodemanager.properties file (located in the directory: <wl-home>/common/nodemanager
In the section "Starting the SOA environment" here - http://middlewaremagic.com/weblogic/?p=6040

Class not found exception for the startup class defined.

iam using weblogic server 10 and bea jrockit 1.5.0.12.
i have created a startup class in the admin console for a web project and i have deployed the war file using the console in a user defined domains, user project directory.
when i start the server, iam getting class not found exception for the startup class.
But, the startup class is available in the web archive (war). how should we add the classes and jars in the war to the classpath in setDomainEnv.sh or is there any other setting available in the console to enable this.

Hello Julius,
yes sure, we can move this post to the NW admin forum. I have already posted similar thread on sun forums. I was hoping that someone from SAP SDN already tackled this problem and if not someone specialized in J2EE Engine could troubleshoot me from the class problem I'm getting. I don't know if it's specific from the agent or if this ClassNotFound is a general SAP J2EE Engine error relating to a library not correclty defined.
Kind regards,

VBWS_MARA_CLASSIFICATION_GET - Class not found exception

Hi,
I`m trying to get the classification and the characteristics from material using VBWS_MARA_CLASSIFICATION_GET. When I test it, it raises the Class not Found Exception for the Materialnumber I`ve given in.
For the Testmaterial classification and characteristics are created.
Can anyone help me? Where could be the problem?

Hi
Use the following BAPI's:
BAPI_OBJCL_GETDETAIL
BAPI_OBJCL_CHANGE
or use the fun module:
CLAF_CLASSIFICATION_OF_OBJECTS.
for getting the classification and characteristics data of Material
instead of VBWS_MARA_CLASSIFICATION_GET.

Class not Found Exception while running an EJB

I have created and published a EJB in Oracle 8i (in a particular
schema) by running the deployejb tool supplied. The ejb was
published successfully. On running the client program I get an
error saying that the mybeans's HomeHelper class cannot be
found. This error occurs when there is a lookup to the home
interface of the bean. The exception thrown says Reasons are
unknown. On checking the objects of type 'JAVA CLASS' I found
that the homeHelper class object had been created automatically
be the deploy process. What is the reason for the class not

I have created and published a EJB in Oracle 8i (in a particular
schema) by running the deployejb tool supplied. The ejb was
published successfully. On running the client program I get an
error saying that the mybeans's HomeHelper class cannot be
found. This error occurs when there is a lookup to the home
interface of the bean. The exception thrown says Reasons are
unknown. On checking the objects of type 'JAVA CLASS' I found
that the homeHelper class object had been created automatically
be the deploy process. What is the reason for the class not
found exception and what can I do to correct it. ?
The code for the beans is as given below :
