For weeks I have been viewing a doggy day care via their web cam. This weekend I upgraded to Lion and have been unable to view the center since. I get an error message for java webcam class not found. All of my software is up to date--suggestions?

For weeks I have been viewing a doggy day care center via their web cam. This weekend I upgraded to Lion and have been unable to view the center. I get an error message for Java plug-in 1.6.0_29 ....webcam class not found. Any suggestions on how to fix this?

Sorry, don't know what else to suggest unless there's a URL to the problem stream that someone here can try. Otherwise we can't test it to try and determine what might be wrong.
BTW, make sure they're testing it with a Mac, not with a Windows system. If they test only with Windows, what they say is or is not working doesn't mean much.

Class Not Found in Server Application

I have set up a basic server application. It contains three files namely
Arith.java (implements the Remote interface)
ArithImpl.java (implements Arith.java the server) and
ArithApp.java which is the client Application
All of these are in the same package. I have compiled all of these files and I execute the rmic ArithImpl command from within the ArithImpl.java file via Runtime.getRuntime.exec(...);
The stub and skeleton files are generated and still I get a class not found exception. I have checked the class path and these files are within the class path.
If anyone could help me I'd greatly appreciate it. Thanks

"Java Class not found in classpath" Error in DESIGNER

Hello All,
I'm trying to connect in Designer using a JDBC connection to MS SQL Server 2008. As per the instructions, I updated my jdbc.sbo file with the path to the existing two JAR files. However, I still get the following error when I try and connect in Designer: "Java Class not found in classpath : C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc\Drivers\sqlsrv". Of course, this error includes the drive path with the location to my JAR files. Any help in resolving this nagging issue is very GREATLY appreciated. Also, if anyone needs it I can post a copy of the jdbc.sbo file to this thread.
Thank you,
Pankaj

Stratos,
Your suggestion didn't help. I tried to connect after restarting my machine and I still get the error. And, I've also tried adding a connection to MS SQL Server 2005 using this JDBC driver, and that didn't help either. Any other suggestions? Would it help to see my "jdbc.sbo" file? Thanks again for your and everyone else's help, and I look forward to your reply.
Regards,
Pankaj

I have also tried to open on 6.1 with similar results.
I am familiar with lookout, however I have taken this project over so I am not sure what I need to do from here.

There are two object (DirectLogic and Meter) that are not present on the amchine you are moving the process to. If the same version of Lookout, you might be able to just copy the cbx files.

Class not found in applet using 2 jar files

I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
The HTML I am using to call the applet is:
<applet code="AMJApp.class"
codebase="http://www.interactived.com/JMTalpha"
archive="AMJ014.jar,plugin.jar"
width="500"height="500"
MAYSCRIPT style="border-width:0;"
name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:
load: class NervousText.class not found.

Hi,
Verify the 3rd party class files names are correctly written in your program. Sometimes wrong case might be the reason.

Class not Found when accessing Proxy class from backing bean in VC.

Hi All,
I'm attempting to access a class of a webservice(generated as a proxy) within my ADF application and invoke the method within a backing bean of the View Controller(bean scope : backing bean). The proxy has generated an ObjectFactory class among other classes. When I access this Object factory class from within the backing bean, the application throws a Class not found error.
I don't know where the error lies since I've declared the View Controller of the ADF application dependent on the Proxy and I've imported the class and accessing it within a backing bean. How would you suggest I approach resolveing this.
JDev : 1.1.1.4
Thank you.
Regards
PP.

Hello Arun,
Thank you for suggesting a Data control, but my requirement isn't to drag and drop the method as a button. It's more of a behind the scnes updating data via a database adapter requirement.
I've resolved the issue. turns out, my deployment archive didn't include the proxy.jpr. Once included it works likea charm.
Thanks
PP.

Service Bus 12c Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Hi,
Did anyone came across this issue with Class not being found for XSLT Function used in transformer on 12c OSB.
I'm using oraext:sequence-next-val and have configured as below:
namespace-uri:http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc
namespace-prefix: oraext
Not sure why at runtime I'm getting below error, as the same was working fine in 11g OSB Domain.
XML-22045: (Error) Extension function error: Class not found 'oracle.tip.pc.services.functions.ExtFunc'

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

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 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 {
public MyServerImplementation()throws RemoteException{
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
l</Trace>
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();
          String UniqueId = new Long(GenTime.getTime() / 1000).toString();
          exptime.setTime(new Date(GenTime.getTime()+TicketTime));
          XMLGregorianCalendarImpl XMLGenTime = new XMLGregorianCalendarImpl(gentime);
          XMLGregorianCalendarImpl XMLExpTime = new XMLGregorianCalendarImpl(exptime);
I am getting the following error
/usr/sap/X7R/DVEBMGS41/j2ee/cluster/server0/./temp/classpath_resolver/Mapcedceb44283d11e0c032000018b99fca/source/com/sap/xi/tf/_MM_test_.java:81: cannot access javax.xml.datatype.XMLGregorianCalendar bad class file: /usr/sap/X7R/DVEBMGS41/j2ee/cluster/server0/./temp/classpath_resolver/Mapcedceb44283d11e0c032000018b99fca/classpath/IA_javax_2.jar(javax/xml/datatype/XMLGregorianCalendar.class) class file has wrong version 49.0, should be 48.0 Please remove or make sure it appears in the correct subdirectory of the classpath. 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
