C++ - Unable to load class for user type- ClassNotFoundException

Hi ,
I'm getting ClassNotFoundException when i try to start the coherence server. I've no clue to solve it.
Any help would be appreciated.
i'm using POF serializer and registering the class using the macro
COH_REGISTER_POF_SERIALIZER(1234,TypedClass<CVOG_AllocationInquiry>::create(), PortableObjectSerializer::create(1234));
i've set the CLASSPATH to my source folder.
i read some posts saying we need java wrapper for this? is that true, do we need java wrapper for all the c++classes that we register.
Here are the details:
my C++ class :
class CVOG_AllocationInquiry : public cloneable_spec<CVOG_AllocationInquiry, extends<Object>, implements< PortableObject> >
     friend class factory<CVOG_AllocationInquiry>;
protected:
     CVOG_AllocationInquiry()

Hi Mark,
i did go thru' the thread and understood that no "pof " mentioning in the cache xml file. I removed the pof config details from the cache xml config file and registersd the c++ class using the macro.
after these, iwas able to start the extended proxy server from consol:
When i try to do the same from my program as :
String::View vsCacheName = "AllocInq-extend";
          CacheFactory::configure(CacheFactory::loadXmlFile(String::create ("/home/hema/workspace/CoherenceClient/config/cache-config_TCP.xml")),CacheFactory::loadXmlFile(String::create("/home/hema/workspace/CoherenceClient/config/tangosol-coherence-override.xml")));
          NamedCache::Handle hCache = NULL;
          hCache = CacheFactory::getCache(vsCacheName);
i get the following error,

Pls can you suggest something, greatly appreciated in advance.
althouh i did observe one thing,, when i start the service from console, the ip is different. But from the program, it displays the different ip that it looks for connection and fails.

  • 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

  • Failed to load servlet Class: MyServletIgnoring: unable to load class:java.

    Hi,

    It is giving the below error:

    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.
    The BEA dev-2-dev site still seems to be active. Try here hunting for a category here: http://forums.bea.com/index.jspa

    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...

  • 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.

  • 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:

    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.

    just a random guess...
    I had a ton of issues with JBoss and jfreechart. JBoss uses a different classloader, and its internal versions of the jfreechart classes will be loaded before yours, causing all sorts of issues. Dig through the jboss directories and you'll find a different, older version of jfreechart of one of its classes. Remove them and you'll be in better shape.
    Alternatively, look around the JBoss docs for how to disable/turn off the unified classloader for your app (its a directive in jboss-web.xml IIRC). This should make the classloader for your webapp perform to spec, getting rid of the class colission issues.

  • Unable to compile class for JSP.       package not found

    Hello folks,
    I was trying to build a simple web application using Eclipse IDE, tomcat 5.x server and ant to build and deploy the application.

  • "open project was cancelled or the application was unable to load database for..."

    I'm doing a project for my Professional Writing course and I
    have to use RoboHelp to create an online help document. The
    professor provided templates for us to use but when I go to open
    the project file I get the following error: "open project was
    cancelled or the application was unable to load database
    for....(then the directory)"
    I know the project file isn't corrupted because the members
    of my class are using the same one without issue. I tried
    re-downloading the file, I also re-installed the program itself,
    still with no luck. I'm using a Trial Version of RoboHelp 6.0 .
    The only other suggestions I have seen are that I don't have
    edit perms for the system, but it's my personal laptop and I have
    full admin privs. I thought at first that the folder was read-only,
    but when I opened it up all it displays is the little green box in
    the checkbox (which doesn't mean the folder is read-only, it's just
    some stupid windows default, it's only read-only if the box is
    actually checked). I tried making the entire directory read-only
    and then turn it off but still get the same error.
    Any suggestions?

    There's a topic on my site about Opening Projects that
    includes the method of deleting the CPD and XPJ files but I didn't
    cover that as the project is good for everyone else. Anything is
    worth a try at the moment though.
    Another thing to try is to rename the course folder, then
    create a new folder with the same name plus all sub folders. Then
    move the files across. That will ensure the folder properties are
    good and not read only. Yes I know what you said but again anything
    is worth a try.
    Also, in the last post you are saying the directory is not
    read-only. I assume the files are all good?
    Ref my previous post, is it the case that now you are getting
    an error before the original error would have popped up?

  • Unable to compile class for JSP

    Please can anyone help me to solve this.
    Actually,this is the condition.
    In my db,there is a table called UserPassword, which has 4
    fields(empNo,UserName,password,level). Now I want to do these things:
    When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
    1)To check the empNo,if it is already exist in the DB,
         if empNo =exist then display error.(record already exist)
         if empNo =notexist then do task 2).
    2)check the UserName,if it is already exist in the db,
         if UserName=exist then display error.(because it's a primary key)
         if UserName=notexist then do task 3).
    3)Create a new user account and save it to the db.
    To do these tasks,I never create a new objects for the tasks 1) and 2).
    only for task 3)create an object.
    Is it the right way?
    Here is the file CreateAcc.jsp
    <%@ page language="java" %>
    <%@ page import="core.UserAccManager" %>
    <%@ page import="data.UserPassword" %>
    <jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
    <jsp:setProperty name="UserAccManager" property="*"/>
    <jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
    <jsp:setProperty name="UserPassword" property="*"/>
    <%
    String nextPage ="MainForm.jsp";
    if(UserPassword.verifyEmpno()){
         if(UserPassword.verifyUsername()){
              if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
          }else{
               nextPage="UserNameExist.jsp";
          else{
              nextPage="UserAccError.jsp";

    <jsp:forward page="<%=nextPage%>"/>The directory structure:
    UserPassword.java- F:/Project/core/data/UserPassword.java
    UserAccManager.java - F:/Project/core/UserAccManager.java

    Are there any mistakes? If so tell me where is it and how to change them.Please help.

    I try it that way, but it don't compile.
    Error:core\data\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    core\data\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Then it compile well.I goto the directory to get the .class files.
    But there is only UserPassword.class inside the data folder. There is not
    UserAccManager.class in the core folder.
    Then I try this way,I put my 2 java files in to a new folder,
    F:\SystemName\com
    When I try it that way, but it don't compile.
    javac -classpath . -d . com\*.javaError:com\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    com\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Now both are compiling well.There was 2 class files.
    I put them in to the WEB-INF/classes/com directory.
    Start the server.But it gave errors:

  • 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.
    What follows is taken from Tomcat/logs/localhost_log.2006-10-24.txt. If there is another log file I should be looking in, please let me know. Here is the full stack trace from the log:

  • 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.
