JSP Unable to Load Class (posted in Java Programming for 5 Dukes)

I hope this isn't a violation of forum etiquette, but I posted my question in Java Programming at http://forum.java.sun.com/thread.jsp?forum=31&thread=203255
I realize now that it may have been wiser to post it here, but I have some replies already and it makes more sense just to inlcude the link.
Can anyone assist with the question at http://forum.java.sun.com/thread.jsp?forum=31&thread=203255
It's worth 5 dukes.

Try changing <tagclass>E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes\tags.ExampleTag</tagclass> to <tagclass>tags.ExampleTag</tagclass>
because <tagclass> tag is for the class name and not the location of class file
And make sure your ExampleTag.class file is in
\WEB-INF\classes\tag\ExampleTag.class
B!

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;

/** Very simple JSP tag that just inserts a string

out.print("Custom tag example " +

} catch(IOException ioe) {

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
I am getting the error: 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
Here is another look at the .java file that I compiled:

Any idea why I am still getting an error?

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

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.
Plz help me out..........

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

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.

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"

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.

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">
<web-app>
<display-name>WebLog</display-name>

JSTL WebLog
</description>
<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" %>

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-name>com.cache.DBCacheStore</class-name>
</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...

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

Unable to load performance pack, using Java I/O on WL60, sp2

Dear friends,
I am seeking help from you. When we start WL60 SP2 on Sun Soloris 5.6, we got
the following exception:

Hoever, the server itself started, and our applications runs ok
(at least so far). But this exception appears every time on some user accounts.
I was wondering what causes this exception. Some user accounts in the same machine
don't have this problem.
I also wondering if it will cause performance problem when the traffic is high.
We already applied the patches.
Any hits and suggestions are welcome.
Thanks in advance.

Dear Deyan,
Thanks for your help. We do have $WEBLOGIC_HOME/lib/solaris in LD_LIBRARY_PATH,
which is set when running ". setEnv.sh" before startWebLogic.sh.
We failed on one patch: 105210-27, for some reason.
The strange thing is: in the same machine, all WL60 instances running under user
accounts (under /users/developers/) have no such error. But it happens under some
account, like accounts under /export/home/, etc. /user/developers is mounted on
another physical machine.

You should have the $WEBLOGIC_HOME/lib/solaris directory in your LD_LIBRARY_PATH
so that
the server can load the performance pack (which is a shared library called
libmuxer.so).
If it is present then do a ldd libmuzer.so and you will see if any libraries
that it
depends on are missing.
Also make sure you have all of the requered patches for 2.6 installed.
