Errors with CF 8.0.1 hotfix 3 and hotfix 4, "Object Instantiation Exception.Class not found"

We need to get our servers up to date with the latest ColdFusion hotfixes in order to pass our security scans and policies. We have been following the Adobe instructions for installing the hotfixes, but we’re getting the same errors each time. The CF 8 hotfix 2 works fine, but once we install hotfix 3 and/or hotfix 4, we get the following errors:
"Object Instantiation Exception.Class not found: coldfusion.security.ESAPIUtils The specific sequence of files included or processed is: C:\ColdFusion\wwwroot\WEB-INF\exception\java\lang\Exception.cfm, line: 12 "
coldfusion.runtime.java.JavaObjectClassNotFoundException:
We have dozens of servers running Windows XP, Netscape Enterprise Server 6.1 (I know, don’t laugh), ColdFusion 8,0,1,195765, and Java Version 1.6.0_04. Just about the only good thing about running XP on our servers is that it matches our development boxes, so we have almost mirrored environments for dev, test, and production. We do NOT have the CF install with the J2EE configuration.
The crazy thing is, on tech note 51180 (http://kb2.adobe.com/cps/511/cpsid_51180.html), it says that the fix for bug # 71787 (Fix for "Object Instantiation Exception" thrown when calling a Java object constructor or method with a null argument under JDK 1.6.) was added in cumulative hotfix 2. However we don’t see this problem until we go to hotfix 3 (or 4).
I’ve also been reading that other people had this same problem, and that the CF 8 hotfix 3 was not compatible with certain versions of JDK, then when you read the Adobe site for CF 8.0.1 hotfix 3, it says “Added the updated cumulative hotfix to make it compatible with jdk 1.4.x, 1.5.x and 1.6.x.”, so that makes me think that Adobe was supposed to have fixed this CF 8.0.1 hotfix 3 JDK incompatability issue - but unfortunately it's still not working for us. We have followed the instructions for removing the jar files and starting/restarting the CF server as directed, we’ve tried this 5-6 times, and still no luck.
Recommendations? Seems like this is a ColdFusion bug to me – one that says is fixed on the Adobe site, but is not fixed in our environment. Please advise, thanks.

For what it's worth, we had an MXUnit user describe a similar, though not identical, problem after installing the latest hotfixes. In his case, he's getting "NoSuchMethodExceptions".

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" error at runtime when ExternalLib DC is included in WD DC

Hi All,
I am getting "Class not found" exception at runtime when external library DC is included in Webdynpro DC.
I am following the below steps..
1) Created a Webdynpro DC - "testProj" to which i need to add the external library DC.
2) Created a DC of type "External Library" called "externaljar"
3)Added Public Parts of type assembly and compilation to the "externaljar" DC (Component Properties Tab -> Public Parts)
4) Right click on the assembly Public Part name -> Manage entities, and added the JAR files as archive.
5)Right click on the compilation Public Part name -> Manage entities, and added the JAR files as archive.
6)Go to Webdynpro DC "testProj" .
Under Component Properties Tab -> Dependencies tab -> Add -> selected the "externaljar" DC -> Next -> for "externaljar" DC checked Deploy time and Run time.
For assembly Public Part and compilation Public Part "build" is selected by default.
7) I did build of both the DC's and deployed it.
Im getting "Class not found" error.
Please let me know where i am going wrong.
Thanks,
Shilpa.

Hi Balakrishna,
If I add Jar files in build path, at run time I dont get any errors, but I get error at comple time. So an external DC is made which includes all jar files in its public part and this DC is added as dependency in the webdynpro project (at deploy time,run time) as in below blog.

Class not found error on Firefox browser

Requirement:-
We have Apache server on the top of a tomcat container where we have deployed application Webnow. This application will provide SSO to another application Imagenow. The requirement is we have to authenticate and authorize a user based on the client certificate which will be installed on the client side browser.
Issue:-
We have achieved the requirement for the browser IE. But for browser Firefox ,we are getting an exception "Class not found". Basically an applet class from the jar is not getting loaded on the Firefox.
Further investigating on this we came to conclusion that Firefox is not able to read the SSL certificate.
In order to eliminate this, we have imported the client certificate in java console as well. After this step, we were not getting "ClassNotFoundException" in FF. But right now, user is getting prompted for certificate/keystore password each & every time while trying to login onto the application (both in IE & FF).
So, we are trying to find ways to remove class not found exception without importing client certificate to java console. Also , is there any way to eliminate the authentication pop up for keystore (though we might not go for this approach as it will be very difficult to manage Java console for end users). Need your urgent help on this issue.
Attaching stack trace of both the browser and screenshot of keystore authentication pop-up . FF_Issue_stacktrace.docx is one when we were getting "class not found exception" and IE_Stacktrace.docx is one for successful case.

We have a similar set up where we have a web app and an applet in a JSP page. You have to put your applet classes up above WEB-INF. So, if your structure for your webapp was:
tomcat/webapps/mywebapp
you'd want your classes under mywebapp instead of webapps/mywebapp/WEB-INF. In your case, if I read your package structure right, you'd want a Log directory under webapp that contains your LogApplet.class file.
I hope this works for you!

Updated document about QuickTime errors with After Effects (re: H.264 and hyperthreading)

I just updated "troubleshooting QuickTime errors with After Effects CS5, CS5.5, and CS6" with information about hyperthreading and Apple's H.264 encoder.
The gist is that Apple's H.264 exporter component for QuickTime fails when the computer has a large number of CPUs.

No, this applies to any QuickTime H.264 export. You can export H.264 in a QuickTime .mov wrapper out of AME, too, and it will have this problem.
The various H.264 encoding presets (for YouTube, Blu-ray, Vimeo, iPad, etc.) don't use the H.264 QuickTime component, so this isn't relevant to them.
This problem is just relevant to choosing Apple's H.264 as the video codec when choosing QuickTime as a format. This applies to all software that uses QuickTime, by the way, not just Adobe software.

Error encountered initializing users and groups ... Class not found.

Hi,
I am trying to set up the example provided in Frank Nimphius and Duncan Mills great article about 'Declarative J2EE authentication and authorization with JAAS' (http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm) on iAS 10g. My current problem is this : when I try to deploy my test application using an ear file, Enterprise Manager returns the following error message : 'Error encountered initializing users and groups using the specified user manager. User manager class oracle.sample.dbloginmodule.DBTableLM.DBTableLoginModule not found.'. This class is distributed in an archive, DBLoginModule.jar, that I have put in my IASHome/j2ee/home/applib and inside my test application /WEB-INF/lib directories. I have tried putting them in one place at a time, then both, with always the same 'class not found' error as result.
Am I missing something ?
Where should I put this archive for it to be seen by the server ?
Could some mistake in web.xml, jazn-data.xml, orion-web.xml or orion-application.xml cause this error ?

"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

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

Error in beanshell - class not found in namespace

We use beanshell to evaluate business rule validations on our application. Below is the calling method...
private Object callBeanShell(final Object parameters, final String expression)
throws EvalError {
if (LogConstants.FINE_ENABLED) {
logger.log(Level.FINE, "Expression: " + expression);
beanShell.set("params", parameters);
Object result = null;
try {
result = beanShell.eval(expression);
} catch (Throwable ex) {
getErrorHandler().fatalError("Expression: " + expression, ex);
if (LogConstants.INFO_ENABLED) {
logger.log(Level.INFO, "Expression: " + expression);
logger.log(Level.INFO, "Result : " + (result == null ? "null" : result.toString()));
return result;
This has been working fine on the application for years, but we've suddenly started getting a problem with evaluations which are called from a SessionBean (via some reflection).
Every time we try and call a certain set of expressions they fail on a 'class xxx not found in namespace'. This happens both when the expression contains code like:
com.chubb.euz.SomeClass sc = new com.chubb.euz.SomeClass(); etc...
or
import com.chubb.euz.SomeClass; SomeClass sc = new SomeClass(); etc...
The strange thing is that when I remote debug it & look at the bsh Interpreter what I see is that it's NameSpace object has a table called ImportedClasses on it which before the eval() call contains just bsh.Interpreter and bsh.EvalError but after the eval() it then contains all of the classes I pull in as imports in the expression passed to it, yet it still manages to throw this damn 'class not found in namespace' error!
It still works whenever else it's called in the app (and this is only happening in our DEV environment). All I can think of now is that it's possibly something to do with the Thread that the beanshell is running on at this time, but that's just a guess as I know bugger all about Threads... I only think this because I can get the thing to work by stopping the processor which was built to run Events (EJB) generated in the app; resetting the Event's Task (regular class) to run again; then restarting the processor (not an option if this goes into PROD with the release!!!)
Unfortunately, re-factoring the validations we need to run at this point is not really an option, as this is all coming at the tail end of a new release & the amount of code changes & subsequent regression testing required would kill us.
This is on weblogic 8.1 - with the beanshell jar just embedded in the main application ear (I ran it with bsh.20b4.jar instead of the 1.3 version we were using but that has no effect).
Any ideas would be more than gratefully appreciated as this is doing my head in!!!

Class not found error for applet.

This is probally a really simple mistake but I've tried everything and can't find it.
My applet works fine with applet viewer - I'm running it from JBuilder. But when I open my html file in the browser it gives me a 'Class not found' error. I've tried running other applets (my own and demos on this site) and they work fine.This is the applet tag code:
<applet code = "Rotary.class" width = "650" height = "580" align = "top">

<param name = "sector0" value ="234,215,244,207,154,43,125,63">
</applet>
The class file is in the same directory as the HTML file. Do I need to specify the codebase? I tried that too - giving it the full pathname of the class.
In the Java console it said that it couldn't find "C:Project\Rotary\javax\swing\japplet"
I don't think it could have anything to do with the fact that I'm using swing because the other applets I used used swing.
Please help - I'm really running out of ideas here!

You have a similar problem like I had.
You seem to have a too old JAVA environment for the browser - I had a too new environment.
For all who are experiencing the same problem!
Problem:
You're compiling your applets with a quiet modern compiler (i.e. Netbeans Version 3.5.1)
You are able to compile your applets without any problems but if you try your applets in "real life", the browsers can't interpret your applets [class not found]. (I tested Internet Explorer 6.0 and Netscape Navigator 4.7)
So you need a plugin for the new JAVA environment because the JAVA environment of the browser is older than that which the applet needs.
Well, you have the choice to demand to every user of your applet to download the new Java Runtime Environment, but then don't wonder why nobody visits your site!
But, don't worry: I figuered out another solution, that Netbeans (www.netbeans.org) allows to compile in different JAVA versions.
Solution:
What you have to do is:
- Install a previous version of JDK (i.e. JDK 1.3 - I would suggest, lower versions don't work with Netbeans 3.5.1 and JDK 1.3 is enough for IE 6.0 and NN 4.7, which I tested)
- Go into the "bin"-directory of Netbeans (i.e. c:/netbeans3.5.1/bin)
- Open the file "ide.cfg" (with notepad or any other texteditor)
- You see a line like: jdkhome "C:\java\j2sdk1.4.2" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- Change the path to your other JDK you wish, like: jdkhome "C:\java\jdk1.3" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- That's it, you can compile your applets in a previous version of JAVA so that "older" browser user don't have to install a plugin for the new JAVA environment.
Have fun!
If you have any questions I would be pleased to help you.
If this tip helped you already I would be pleased if you would send me a quick email with your experience.

Class not found error for COM.ibm.db2.jdbc.app.DB2Driver

i have written this code:
import java.io.*;
import java.sql.*;
public class tryjdbc
{ public static void main (String args[])
{ try
{ Class.forName("COM.ibm.db2.jdbc.app.DB2Driver"); }
catch (java.lang.ClassNotFoundException e)
{ System.out.print(e.getMessage()); }
and once i try to run it, it gives out a class not found exception error.
I haven't changed anything with the classpath since I don't think the problem is with the classpath. I have read in the IBM Developer Kit for Java documentaton that the AS/400 Developer Kit for Java automatically adds the db2_class.jar file to the classpath. So why do I get a class not found exception error?

I was using Web Spehere 4.0.3 and trying to connect to a database on DB2 7.2. I was just following a tutorial and trying to get a handle on Web Sphere. I am running all of these on a Windows 2000 Operating System. Here are some of my observations :
a. db2java.zip packaged under %DB2ROOT%\SQLLIB\JAVA, does not work.
b. CLASSPATH needs to be set to %DB2ROOT%\sqllib\java12\db2java.zip
c. Include this as one of the packages in the package defined in
WebSphere, using the Java Perspective.
d. Ensure that case sensitivity is respected. All though the package
shows up as COM.ibm.db2.jdbc.app.DB2Driver, for some reason, it
will only accept com.ibm.db2.jdbc.app.DB2Driver.
With these settings, I was able to connect to a db2 database.
I am a little puzzled on the following. I did not include java.io package, but still it could print the messages. Did anybody have a similar experience
Thanks for this posting.

Compilation Error for import classes not found in generated Proxy Class

Hi,
We are generating java classes for the COM dll using JCOM com2java compiler.
We are getting a compilation error for import class not found when compiling the
generated Proxy java source code. It can't find the com.bea.jcom.Dispatch class that
the generated Proxy java source code extends. It also can't find com.bea.jcom.Variant
or com.bea.jcom.Param. These are interfaces or data types or classes used by COM
library.
I added weblogic.jar to my class path and the only Dispatch class i found inside
the weblogic.jar is com.linar.jintegra.Dispatch;
We have com objects for which we want to develop an EJB client to interface with
the COM object using JCOM with Native Mode disabled.
Any help on the compilation error..I tried changing the extends for Dispatch to com.linar.jintegra.Dispatch
but the other errors are still there.
To begin with, I think the generated code should not refer to any of the COM data
types.
Any help please.
Thank you in advance,

Hi,
I resolved the other errors by changing all references from com.bea.jcom.Variant
etc to com.linar.jintegra.class name..all were present under the com.linar.jintegra
package.
Thank you all anyways,
