Overriding eventdistributionpattern-pof throwing unable to load class error

Hi,
We were trying to override the "coherence-eventdistributionpattern-pof-config.xml" with our own event distribution pof due to conflicintg type-id's. We changed type-id's for few of the classes. We changed the type-id for the following classes and left others as such.
com.oracle.coherence.patterns.eventdistribution.EventDistributor$Identifier
com.oracle.coherence.patterns.eventdistribution.events.DistributableEntry
com.oracle.coherence.patterns.eventdistribution.events.DistributableEntryInsertedEvent
com.oracle.coherence.patterns.eventdistribution.events.DistributableEntryUpdatedEvent
com.oracle.coherence.patterns.eventdistribution.events.DistributableEntryRemovedEvent
When i start the coherence server, i get error in loading class "com.oracle.coherence.patterns.eventdistribution.channels.cache.ParallelLocalCacheEventChannelBuilder" for which we did not change the typ-id at all.
Coherence version 3.7.10

Eclipse Plugin Creation - "Plug-in name was unable to load class " error

Hi everybody and happy new year to you all,
i got a little problem again. I have written the first lines of code of my plugin and wanted to test it (run as Eclipse Application). I got the following error-msg, when clickin either on the menu item or toolbar button:
"Could not create action delegate for id: org.eclipse.tui.inpulse.actions.InpulseStart
Reason:
Plug-in org.eclipse.tui.inpulse was unable to load class org.eclipse.tui.inpulse.InpulseStart."
My project has the following properties (of which i read they are important):
Source folder: org.eclipse.tui.inpulse/src
Output folder: org.eclipse.tui.inpulse/bin
Dependencies: org.eclipse.ui, org.eclipse.core.runtime
Extensions: org.eclipse.ui.actionSets
ExtensionsPoints: none
The following is my plugin xml:
<plugin>
   <requires>
          <import plugin="org.eclipse.core.resources"/>
        <import plugin="org.eclipse.ui"/>
    </requires>
    <runtime>
          <library name="Inpulse.jar"/>
    </runtime>
    <extension
          id="org.eclipse.tui.inpulse.InpulseActionSet"
          name="org.eclipse.tui.inpulse.InpulseActionSet"
          point="org.eclipse.ui.actionSets">
        <actionSet
            id="org.eclipse.tui.inpulse.InpulseActionSet"
            label="Inpulse"
              visible="true"
         description="The action set for the Eclipse Hello World example">
         <menu id="org.eclipse.tui.inpulse.InpulseMenu" label="Inpulse">
               <separator name="samples"/>
         </menu>
         <action id="org.eclipse.tui.inpulse.actions.InpulseStart"
               menubarPath="org.eclipse.tui.inpulse.InpulseMenu/samples"
               toolbarPath="Normal"
               label="Inpulse"
               tooltip="Start pattern search."
               class="org.eclipse.tui.inpulse.InpulseStart"/>
        </actionSet>
   </extension>
</plugin>The javafile "InpulseStart.java" is in the "org.eclipse.tui.inpulse" package and has the first line "package org.eclipse.tui.inpulse;". The class "InpulseStart" implements "IWorkbenchWindowActionDelegate".
So the following members are implemented:
public void run(IAction proxyAction){...};
public void selectionChanged(IAction proxyAction, ISelection selection){...};
public void dispose(){...};
//and some additional ones ;-)I really dont know what i do wrong. If you have an idea, what i just miss out or do wrong, id be glad if you helped me out!
Cya

Aye, you are right, i should/could have posted this somewhere else. I just hoped, that i can get a good answer here, cause ppl helped me out very nice before.
Im sorry if i offended users of this forum...
The "advice" is recognized and i will post somewhere else in case i have a eclipse specific problem.

Wrapped: Unable to load class "com.cache.DBCacheStore"

Hi,
I was trying out a sample application for using DBCacheStore and getting the following error...
(Wrapped: Unable to load class "com.cache.DBCacheStore" using sun.misc.Launc
her$AppClassLoader@13f5d07
<class-scheme>

</class-scheme>) java.lang.ClassNotFoundException: com.cache.DBCacheStore
I have the CLASSPATH set to the location of DBCacheStore.class file both in cache-server.cmd and in my application startup JVM params. But still i am not able to resolve this issue. However i am still able to hit the database and get the values for the first call and on sub-sequent call, i am able to retrive the value from cache. I also encounter the below error, after i have retrieved the values from cache...

I have recently written a custom tag but I have been unable to implement it in a JSP because the server is unable to load the .class file. Below I have supplied the files that contribute to make up the custom tag, aswell as the JSP file used to implement it.

Unable to load class from JSTL

Hello. I am using JSTL 1.06 from Jakarta with Tomcat 4.1 on a MacOS X 10.3.9 server. I have a jsp that contains the following:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<jsp:useBean id="validate" class="mypackage.ValidationBean" scope="request">
        <jsp:setProperty name="validate" property="*" />
</jsp:useBean>
<c:if test="${validate.valid == false}">
The input is not valid.
</c:if>In case it matters, my web.xml file starts out like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">I have placed jstl.jar and standard.jar in my webapp's WEB-INF/lib directory. However, when I try to load the page, I get this error message:
org.apache.jasper.JasperException: /myjsp.jsp(60,0) Unable to load class if
I know that many people have asked similar questions, but in each case, the response was to put jstl.jar and standard.jar in WEB-INF/lib and make sure that you're using the proper URI for the taglib, and I think I have done those things correctly. Any help would be greatly appreciated!

Thanks for your response! In answer to your questions:
The JRE is 1.4.2_09. I can't use 1.5 (5.0) without upgrading the OS.
I haven't tried it on a PC. I might be able to, but it would take me some time to set everything up.

ITunes 10.5.3, Unable to Load Class Data from Sync Services, Crashes Repeatedly

Ever since iTunes 10.5.3 on my Windows 7 x64 box, I've been having serious problems keeping iTunes running:
1) Any time I connect my iPhone or iPad, or any time they attempt to sync over WiFi, I get the 'Unable to load class data from sync services' error. It's worth mention that the iPhone or iPad do actually then proceed to sync correctly, and all media / data is synchronized successfully, as far as I've been able to tell. I've reset sync history, restored the iPhone and iPad, manually moved the SyncServices directory, set both the iPhone and iPad up as new, completely uninstalled iTunes and the mobile device software, re-installed, and *nothing* I do fixes this issue or even seems to impact it. Uninstalling iTunes 10.5.3 and reinstalling iTunes 10.5.2 resolves this error.
2) iTunes 10.5.3 has serious crashing problems on my machine, though I've searched through forums and found a lot of other people with the problem. In my case, sporadically as iTunes access the iTunes store (for example, I can always make it happen by subscribing to the Diggnation podcast and telling it to refresh the podcast), I get a full application crash which generates the following event in the event log:
Faulting application name: iTunes.exe, version: 10.5.3.3, time stamp: 0x4f14cc3d
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0x80000003
Fault offset: 0x0001280c
Faulting process id: 0x564
Faulting application start time: 0x01cce78789dc009a
Faulting application path: D:\Program Files (x86)\iTunes\iTunes.exe
Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
Report Id: ecc77400-537a-11e1-b809-00248c196007
Again, uninstalling iTunes 10.5.3 and re-installing iTunes 10.5.2 fixes this issue as well, but I really shouldn't have to do that. Is there any actual solution to these problems other than dowgrading to an older version?
Yes, I'm running current malware protection (and my system is clean) and yes, I've already checked any other obvious culprits to make sure I don't just have a corrupt library or file somewhere that's causing it. My Windows 7 install is completely up to date from a Windows Update perspective and also from a driver perspective (even including the motherboard and chipset drivers). I made sure to do a system file integrity check (sfc /scannow) and it confirmed my install of Windows isn't suspect, but beyond all that I was able to reproduce these failures on a completely separate machine running Windows 7 x64, without any of my media library or data on it -- iTunes 10.5.3 just seems to be bad news on Windows 7 x64 for me, even though I know there are definitely people are using it successfully. I don't get any other application crashes for any other applications, and I've never had an issue like this with any previous version of iTunes...
Last but not least, in case it matters, I'm running iOS 5.0.1 on both the iPhone4 and the iPad2. The iPhone4 is the GSM AT&T model and the iPad2 is the CDMA Verizon model.

OK, I've given up. Uninstalled iTunes 10.5.3 permanently. It's a shame, 10.5.2 works perfectly but 10.5.3 is a complete and total cluster for me.
Anyone with the same problems who hasn't done this already, just uninstall iTunes and the Apple Mobile Device Service in your Add/Remove Programs, then re-install iTunes 10.5.2. You won't lose your library or any settings or apps, it will just go back to working again.
I wish Apple would acknowledge this so that I'd at least know it would be fixed in the future.

JSP Unable to load class

I am using the core servlets book and Tomcat 3.2.4 to learn JSP. The first example will not work because of the follwing exception:
org.apache.jasper.compiler.CompileException: E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\jsp\SimpleExample.jsp(14,7) Unable to load class E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes\tags.ExampleTag
I have the following files in the following paths:
ExampleTag.java is in the path E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes\tags.ExampleTag and the code is as follows:
package tags;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
import java.io.*;
/** Very simple JSP tag that just inserts a string
* ("Custom tag example...") into the output.
* The actual name of the tag is not defined here;

public class ExampleTag extends TagSupport {

out.print("Custom tag example " +

} catch(IOException ioe) {
System.out.println("Error in ExampleTag: " + ioe);
return(SKIP_BODY);
This is an excert from the Tag Library Descriptor file named csajsp-taglib.tld (the entire file is too long to include). This is in path :E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\jsp

I have tried putting the ExampleTag.java file and the folder that it is in, 'tags', in about every path I can think of and I get the same error. I also tried removing the entire path from the .tld file and just calling for tags.ExampleTag. Still no luck.
I am using win98.
Any assistance will be greatly appreciated.
Thanks,
Scott

I compiled the .java and put the .class file in the following path:
E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes\tags

Any idea why I am still getting an error?

Do not seem to be able to backup iPad via iTunes on to my PC. Message after connecting is "iTunes was unable to load class information from Sync Services, Reconnect or try later" Have tried that but get the same result. Can anyone assist?

Do not seem to be able to backup iPad via iTunes on to my PC.
Message after connecting is "iTunes was unable to load class information from Sync Services, Reconnect or try later"
Have tried that but get the same result.
Remedies I've tried are:
wait and try again
reboot
reload iTunes
NB hp is a relatively new machine and has previously backed up quite happily.
Can anyone assist?

RHoodnkt-
Try rebooting the iPad. Hold down both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow. It takes a minute or two to restart.
Also be sure your iPad battery is not completely discharged.

"iTunes was unable to load class data information from sync services"

I own iTunes 10.5 beta 3 64-bit for my 64-bit windows 7 pc, and it gives me this message whenever I try to sync ANY of my devices: "iTunes was unable to load class data information from Sync Services". I own an old iPod video and an iPhone 4 with iOS 5 beta 3. I've tried uninstalling all Apple products, searching through my hard drive and deleting everything Apple, cleaning the registry, EVERYTHING. I've reinstalled at least 4 times now. The problem refuses to become fixed. I've searched every article online possible, and none of the solutions have worked. Is there anything I can do to get my stuff back on to my devices???

In the course of your troubleshooting to date, have you worked through the following document?
iTunes for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert

Hi,
I am using WebLogic Server 10.0, i deployed my application in that.
It is giving the below error:
Failed to load servlet Class: MyServletIgnoring: unable to load class:java.lang.
ClassNotFoundException: Class bytes found but defineClass()failed for: 'MyServle
If it is the wrong place(forums category), please do ignore.

Probably not the right forum. But you have the honour of being the first person to ask a specific WebLogic Server question here.

Class.forname - Unable to load class if two jars with same package name

class.forname - Unable to load class if two jars contains same package name exists in classpath.
JVM is stopping search for class one it finds the package name in the jar file that is ahead in classpath,
JVM is not continuing search in the remaining jar files.
For this , I put the jar file that contained class ahead of of ther jar file containing same package name, then it worked.
Is this a JVM bug ? (JDK 1.5)

I reported as bug to sun. I got auto email, looks they have not assigned any Bug ID so far.

JSTL : unable to load class

Hi,
I know this is one of the jstl + tomcat problem again, but I need some help here. I think I've got everything right, but it seems Tomcat can't load the relevant class.
I was try run this free source code, but got this error:
org.apache.jasper.JasperException: /index.jsp(13,0) Unable to load class box
I'm using Tomcat 4.1.27-LE-JDK1.4
This is in my JSP file:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="tldc" uri="/tldc" %>
the standard tld works fine, but I think the user-created tld is causing the problem.
This is my file structure:
webapps/jstl-blog/WEB-INF/tlds/tldc.tld
My web.xml file is:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/j2ee/dtds/web-app_2.3.dtd">

<taglib>
<taglib-uri>/tldc</taglib-uri>
<taglib-location>/WEB-INF/tlds/tldc.tld</taglib-location>
</taglib>
</web-app>

This is in my JSP file:
<%@ taglib prefix="c"
uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="tldc" uri="/tldc" %>
Try this instead:
<%@ taglib prefix="tldc" uri="/WEB-INF/tlds/tldc.tld" %>

CLDC: Unable to load class javax/microedition/io/SocketConnection

I'm trying to connect Palm (with PalmOS 3.5) to PC via sockets. Client application that is on PDA is compiled without error and deployed as well without problems. But when it tries to execute Connector.open(), IOException is thrown with the message "Unable to load class javax/microedition/io/SocketConnection". What is wrong with that? I guess i did everything well...

Ok. I got it but not hte way I wanted. Maybe someone could explaine me. Instead of casting to SocketConnection, I casteded to StreamConnection that is a superinterfece for SocketConnection and the URI argument for Connector.open() remained the same, e.g. "socket://xxx.xxx.xxx.xxx:xxxx".
What is the problem to SocketConnection? It is declared in CLDC and must be supported by vendors, but it's still unloadable...
