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.

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

Two query with same technical name in Quality

Hi experts,
I have two queries in Quality with same technical name. I used the program RENAME_DUPLICATE_ELEMENTS to rename the query and its renaming the latest query instead of the old Query. I am in BI 7.0 system and cant find a note that applies to BI 7.0. There are quite a few notes on 3.x system. Has somebody faced the same problem. What did you do. If there is a note for bi 7.0, please let me know so i can resolve with the Basis team.

We had similar issues - this happens when you create a query locally and then transport the same.
The queries have an internal GUID which is generated locally and this causes duplicates.
You can :
1. Delete queries using the GUIDS ( you can find this in RZCOMPDIR or RSRREPDIR tables ) using RZDELETE to delete queries.
identify your older version query and then delete the same and you should be good to go...
also try identifying the same using program
ANALYZE_RSZ_TABLES

How to get two fields with same tech name in LIS Extractors?

Hi Experts,
I need "ERDAT" field from two structures (QMSM & QMFE) in 2LIS_18_IOTASK extractor.
In LBWE first I moved ERDAT from QMSM. When I moved ERDAT from QMFE it gives an error:
"Field with same technical name is already available in the Extract Structure".
I don't want to create Append Structure as we need to write User exit.
Can any one tell me how to get this field added in the extractor from QMSM and QMFE?
Thanks for your help.
Regards,
Sree

this is not possible as the all those fields are put in one structure. per definition you can't put the same field name twice in a structure, table in the data dictionary...
hence, you really need to use an append and fill via user exit

Syncing two computers with same short name

Hi folks, esp. Dancing Brook ,
So, I have a computer at work, a laptop at home, and a Palm PDA. Since both computers are mine, they have the same short name. I only make iCal entries on my work computer (plus anything that I enter in my PDA, of course), but like to have the latest iCal data on my laptop too. Here's my question:
I only have iCal on my laptop for the convenience and as an extra backup. Since, however, it shares the same short name as my work computer, do I have to worry about sync issues? E.g., if my laptop iCal has old data, could it overwrite the new data if I sync it after I sync my work computer?
I've read that changing the short name of your computer isn't a great idea, FWIW.
Thanks,
PL

Don't know. Wouldn't think it would be a problem as it is too likely to happen (ie same name on both computers). But you could setup a new account with a new name on the laptop if you don't want to experiment. I would just backup and experiment, or set up two new users, one on each computer along with a trial .Mac account.

Problem when deploying on tomcat two applications with same appmodule name

We have deployed two different adf-uix applications to a tomcat application server.
Each of the two applications has one application module, the two application modules have the same name. This seems to cause a conflict between the two applications.
After starting the application server, we can run first the application 'A' and then the application 'B' or viceversa, every time the first application works and the second doesn't. When running the second application we get messages like 'table or view doesn't exist'.
Having the application modules with different names seems to solve the problem, but it seems not so easy to change the application module name on an existing and rather complex application.
Any suggestion? Please help.
Thanks, Mauro

I had the same problem and the only way to solve it was to change the app module name.

Two attached libraries with same package name

Hi everybody!
Excuse my bad english,
I have a Form (in Borms 6i) with 2 attached librairies. In these libraries, I have 2 packages and 2 procedures with the same name.
How I can call the good one in specific library?
Thanks so much
Valerie

Valerie,
I don't think that there is a solution for this and Forms always picks the procedure of teh library you attached first. Is renaming the functions and procedures and option ?

Two cams with same file-name...

Hi! I have had an EOS400D for a couple of years, and have recently bought a 40D. The problem now is that the 40D has been used so much on a trip to the Philippines, the camera´s file numbering are the same on a series of pics. Both cams used simultanously. This confuses Aperture, so when i preview one pic, another shows up... Doues anyone have a solution for this?

That's got nothing to do with the file names, as Aperture uses it's own internal IDs to keep track of each image, regardless of file names.
What's happened is that the thumbnails for each image and the index which tells Aperture which thumbnail is for which image don't match up.
To fix this you need to rebuild the Library - quit Aperture, then launch it again while holding down the Command and Option/Alt keys. This will rebuild the database from scratch.
Obviously, don't do this until after you've backed everything up, just in case...

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

Hi,
I was trying out a sample application for using DBCacheStore and getting the following error...

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...

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.

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"
    "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.

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

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

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,

I compiled the .java and put the .class file in the following path:
