Optional Package class reference at server startup...gives class not found

I have a enterprise app having a webservice..the webservice (servlet) gets instantiated on server startup…It has reference of a class which is an optional package
All the manifest entries are correctly added to the ear..manifest.mf..
When the servlet is initialized at startup.. gives me a class not found error…
However, the app works fine..this is just a one time error(whenever the app is deployed fresh..)..
Any help would be appreciated
Thanks

RMI Server Class not found

I am facing a problem when i am going to generate Stub and Skeleton using rmic command, but it gives the error that
Error: "class not found"
Please help me.its urgent.

Run rmic -depend to ensure that any classes referenced by the server classes are also compiled. Also, run rmic from inside the directory of your project beside the root of your package.
ie:
Work directory: work/
Classes are in: work/com/yourdomain/rmistuff/CoolServer.java
Then cd into directory work/ and run:
rmic -depend -verbose com.yourdomain.rmistuff.CoolServer
Try this and see what happens.

Class Not Found in Server Application

I have set up a basic server application. It contains three files namely
Arith.java (implements the Remote interface)
ArithImpl.java (implements Arith.java the server) and
ArithApp.java which is the client Application
All of these are in the same package. I have compiled all of these files and I execute the rmic ArithImpl command from within the ArithImpl.java file via Runtime.getRuntime.exec(...);
The stub and skeleton files are generated and still I get a class not found exception. I have checked the class path and these files are within the class path.
If anyone could help me I'd greatly appreciate it. Thanks

Class not found exception for the startup class defined.

iam using weblogic server 10 and bea jrockit 1.5.0.12.
i have created a startup class in the admin console for a web project and i have deployed the war file using the console in a user defined domains, user project directory.
when i start the server, iam getting class not found exception for the startup class.
But, the startup class is available in the web archive (war). how should we add the classes and jars in the war to the classpath in setDomainEnv.sh or is there any other setting available in the console to enable this.

Hello Julius,
yes sure, we can move this post to the NW admin forum. I have already posted similar thread on sun forums. I was hoping that someone from SAP SDN already tackled this problem and if not someone specialized in J2EE Engine could troubleshoot me from the class problem I'm getting. I don't know if it's specific from the agent or if this ClassNotFound is a general SAP J2EE Engine error relating to a library not correclty defined.
Kind regards,
Tanguy Mezzano

Servlet class not found error deploying a WAR on Web Logic Server 8.1

I'm re-deploying an updated web application to a web logic server, but when I navigate to the login page of the web application to test it, I get a class not found error for my login servlet. I have both the web.xml and the weblogic.xml descriptors in my WEB-INF directory, and all of my compiled classes are in the WEB-INF/classes directory, is there something else I'm missing? Any help would be much appreciated.

Thanks for the response. Here's the web.xml file:

None of the classes are in a package (I know it's not the best idea, but I didn't write these, I'm just doing some updates). So the file structure is pretty much just WEB-INF/classes/
At the moment I've got a fix by just putting the entire project (not in any sort of archive) on the server itself instead of deploying it as a WAR, any thoughts on why the WAR isn't working would be much appreciated though.

Not able to start the remote server - class not found exception

All,
I am quite new to RMI programming, although i am an experienced java programmer. I am facing a problem in starting the remote server program which i wrote for RMI. I am getting class not found exception for "stub" class eventhough the class is in the classpath.
Following is the error console:

public interface MyRemoteInterface extends Remote {

MyRemoteInterface remObj = (MyRemoteInterface) Naming.lookup("rmi://localhost:1985/GetNames");
System.out.println("Names are "+remObj.getNames());
catch(Exception e) {
System.out.println("Problem encountered accessing remote object "+e);
}

That's a remote exception coming from the registry. You need to learn to recognize remote exceptions and their source, it's a mjaor source of confusion in RMI.
In this case it's the registry that can't find the stub class.
The stub class needs to be in the CLASSPATH of (i) the Registry and (ii) the client as well. Ditto the remote interface; ditto any application classes it refers to, and so on until closure.
The easiest way to achieve (i) is to start it in the server's JVM, with LocateRegistry.createRegistry().

Never mind....the problem had to do with my CLASSPATH....

Struts class not found for war file

Hello,
I am tring to deploy my struts web application in weblogic 8.1. I have all the
library files in web-inf\lib directory. It gave me the error that class not found

I can use javap to find the class using the same classpath. Could any one point
me some direction what I am doing wrong here.
Thanks.

Hello Mark,
Your suggested solution (putting an empty commons-logging.properties into
web-inf/classes or in a jar in web-inf/lib)
does not make any change at all. It still complains about not being able to
preload the servlet and still
gives exceptions upong calling upon LogFactory.
What I have been able to do is put the three classes from
com.bea.wlw.netui.util.logging into a separate jar
and add that to web-inf/lib.
However I am sometimes getting funny exceptions upon undeploy
(NoClassDefFoundError for org.apache.commons.collection.FastHashMap$KeySet).
Regards,
Robert Varga

From a FAQ on netui:
1. Why do I get a ServletException while trying to deploy a struts web
application on a Workshop/Integration/Portal domain?
In the "<WL-HOME>/server/lib/knex.jar" file there is a properties file
called "commons-logging.properties" which configures the
com.bea.wlw.netui.util.logging.StrutsLogFactory class for Struts loggingas
below:
org.apache.commons.logging.LogFactory=com.bea.wlw.netui.util.logging.StrutsL
ogFactory
This class file is not available for a Struts web application that was not
built using Workshop, the reason being the containing NetUI jar files are
not present in the web application's WEB-INF/lib folder. This leads to a
ServletException while deploying the web application. The solution is toadd
a blank file (or a JAR containing the file) namedcommons-logging.properties
to the server CLASSPATH, or to the WEB-INF/lib folder of the concerned web
application. This issue will be fixed in Service Pack 2.

Hi Rob,
I also have a similar error with deploying a Struts web application into
a
8.1 Basic Workshop Domain created
by 8.1 Platform.
I get a ClassNotFoundException for 'com.wlw...StrutsLogFactory', whenStruts
tries to load any Jakarta class
from commons-beanutils or Struts which has logging.
This happens because commons-logging picks up some property whichinstructs
it to load that class, which is
naturally not included in most web applications, since it is
workshop-specific. This property definition, I think,
is in <bea>\weblogic81\server\knex.jar, called
commons-logging.properties,
containing the following line:
org.apache.commons.logging.LogFactory=com.bea.wlw.netui.util.logging.StrutsL
ogFactory
How can I override this in my webapp in a property file, so that when a
Struts or Beanutils class calls
LogFactory.getLog(org.apache.....<classname>.class), it would not try touse
the property file and the
class defined in knex.jar.
Thanks in advance,
Robert Varga

Actually it complained about a NoClassDefFoundError. Generally this
is
caused by something in a parent classloader that is found but then
depends on something only loadable in a child classloader.
eg.
You have something in your $CLASSPATH that references something in the
WEB-INF/lib. This will NoClassDefFoundError.
So, as I recommended, remove everything you've added to the$CLASSPATH,
add the jars to WEB-INF/lib. If you're still having problems, show me
your $CLASSPATH, the contents of WEB-INF/lib, and the error message
/stack trace.

Hello, Rob,
I did put the common-beanutils and other jar files in the

And from the weblogic console, I do see the jar file get included in

(those generated file name have some number attached at the end.)
As
I
mentioned
before, I can use javap find the class using this weblogic generatedclasspath.
But weblogic complained that the class is not found.

B2B Java Callout Class not found exception

Hello B2B Gurus,
I am facing class not found exception, when trying to call a java code from B2B and below the configuration done from B2B side.
Could you please help me to identify that the configuration done suffice the requirement
1.Created a call out from
Adminstration-- Callout-- Create Callout -- XXJavaCallout(Name of the Java Callout)
Administration-- Callout Details -- Implementation Class -- XXClassFileName
Administration-- Callout Details -- Library Name -- XXJarFileName.jar
Administration-- Configuration -- Callout Directory -- xx/yy/zz (UNIX server that is accesible from B2B)
2.Partners--XX--Delivery Channel -- Select the channel where we need the call out -- Channel Attributes -- Transport Callout -- XXJavaCallout
3.Agreement--Callout -- XXJavaCallout
Place the jar file in xx/yy/zz UNIX location.
Please let me know if any steps I have missed for using the callout functionality.
Thanks,
Sunil
Edited by: Dathu Sunil on Mar 29, 2012 8:17 AM

Sunil,
Administration-- Callout Details -- Implementation Class -- XXClassFileNameMake sure that you are giving complete name of the class (without extension .class.). For an example if your class name is Sample and it is in package a.b.c then give class name as a.b.c.Sample
Administration-- Configuration -- Callout Directory -- xx/yy/zz (UNIX server that is accesible from B2B)This must be valid directory existing on machine where B2B is installed.
2.Partners--XX--Delivery Channel -- Select the channel where we need the call out -- Channel Attributes -- Transport Callout -- XXJavaCallout
3.Agreement--Callout -- XXJavaCalloutTransport Callout and Agreement Callouts are used for different purpose. Are you sure that you really need both in your case?
You may like to refer -

Class Not Found instantiating IP

[Portal 4.0 on WLS 6.1 on Win2K... ]
I'm getting 'Class Not Found' when instantiating my IP class. The only way I can
work around it is to put "WEB-INF/classes" in the startup classpath, which makes
it not re-deployable.
I've read newsgroups/docs extensively and believe that:
* IPs (as opposed to PCs) are scoped to the web app, not to the enterprise app
* For web apps, the WEB-INF/classes (for exploded files) and WEB-INF/lib (for
Jar'd files) should be 'auto-included' in the classpath, hence the classloader
that portal is using for IP instantiation should find my class...
But that's not what's happening... so where is my understanding faulty and, more
importantly, how can I make portal find my IP class and still have it be hot redeployable?
Thanks in advance,
Mike

Hi,
We actually use a third approach, which is: package your pipeline components
with a dummy EJB into a separate JAR (unless you programmed the actual EJBs
which you want to package with your PCs) and deploy as a separate component
to your enterprise app.
We include pipeline.jar and p13n_util.jar into the classpath in the ANT
script only. WLP starts without these jars in the class path with no
problems.
Just for a reference: we use WLS 6.1 sp2, WLP 4.0 sp2.
Best regards,
Michael Goldverg

"The set-environment.bat had been modified to include the WEB-INF/classesunder

is the right thing to do; I no longer get the 'class ... can not bedeployed'

Yes, putting anything in the enterprise application or the web applicationin
the system classpath is not a good idea.
"So, the (very cool & useful) diag tool"
Glad you like it! I wrote that a year ago, and it has helped me onnumerous occasions.
Whenever you have a classloader problem, this thing works magic.
" 'You need to either put your PC in pipeline.jar or reference your ownJAR from
the pipeline.jar's classpath entry in its manifest.' I'm not sure Iunderstand
this. Are we really expected to modify BEA supplied JAR files?"
Regretably, yes. There have been several ideas on a better solution, butit hasn't
found its way into the product yet. Until that happens, the secondapproach (changing
the manifest classpath entry) is the preferred approach.
"Thank you *very* much for your help!"
I'm happy to help!

Oracle.forms.webutil.ole.OleFunctions class not found

Hi all,
I am getting oracle.forms.webutil.ole.OleFunctions class not found at design time in Forms Builder 10gR2 as well as at run time when working with webutil. Webutil is properly configured. I am using file uploading and downloading and it is working fine. but when I m working with CLIENT_OLE2, it is giving class not found exception. Can someone please help me to identify the problem.
Thanks in advance
Bilal

hi
Forms [32 Bit] Version 10.1.2.0.2 (Production in this version the webutil is already installed but u have to sign jars and there is also some modifications
in formsweb.cfg.
please check this.
How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: [OraHome] is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
[OraHome] with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
[JacobStage] is the folder where you extracted Jacob, and will end in ...\jacob_18
     cd [JacobStage]
     copy jacob.jar [OraHome]\forms\java\.
     copy jacob.dll [OraHome]\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add [OraHome]\jdk\bin to the PATH:
     set PATH=[OraHome]\jdk\bin;%PATH%
Sign the files, and check the output for success:
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\frmwebutil.jar
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open [OraHome]\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
     CREATE USER webutil IDENTIFIED BY [password]
     DEFAULT TABLESPACE users
     TEMPORARY TABLESPACE temp;
     GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
     CONNECT webutil/[password]@[connectstring]
     @[OraHome]\forms\create_webutil_db.sql
     -- Inspect SQL*Plus output for errors, and then
     CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
     grant execute on webutil_db to public;
5) Modify [OraHome]\forms\server\default.env, and append [OraHome]\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Start the OC4J instance
7) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in
Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
8) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
         NULL;
to avoid having to connect to an RDBMS (optional).
Create a new button on a new canvas, with the code
         show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
9) Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
      http://server:port/forms/frmservlet?config=webutil
10) Run your form.sarah

Service Bus 12c Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Hi,
Did anyone came across this issue with Class not being found for XSLT Function used in transformer on 12c OSB.
I'm using oraext:sequence-next-val and have configured as below:
namespace-uri:http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc
namespace-prefix: oraext
Not sure why at runtime I'm getting below error, as the same was working fine in 11g OSB Domain.
XML-22045: (Error) Extension function error: Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Have you restarted servers after putting jar in $Domain_Home/lib directory? Also try after explicitly adding this jar in classpath by editing server startup script (startManagedWeblogic.cmd or .sh) or in domain env setting script (setDonainEnv.cmd or .sh) and restarting the servers.

Anuj

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!!!

Hi,
Thanks for the reply.
I am trying to reverse SAP tables. Initially the Reversal process stuck at Set MetaData step. I stopped the session and restarted it then Set MetaData completed successfully but Set FlexFields give the error.
Any idea?

Hi Mark,
I have seen your two posts and there are something you need to notice:
Where the ClassNotFound exception you got? From deployment tool or
application server kjs process?
Of course, you need not to add supporting classes to each ejb jars or ears.
1. If you use deployment tool to package your application, I'm sure you'll
fail to resovle your classes without supporting classes added to jars.
Please select Edit->Preference,in Classpath entry, enter the supporting
classes(packaged to jar files) location. This should work.
2. After deploy to ias, please edit the registry using kregedit which you
described in your posts.

Johnson

When I deploy EJBs to the iPlanet app server I find that I need to include
all supporting classes in each ejb jar file. According to the
Administrator's manual I should be able to modify the kjs classpath bydoing
the following:
On Windows
a.. Open iPlanet Registry Editor.
(See About iPlanet Registry Editor)
b.. Open the following key:
SOFTWARE\iPlanet\Application Server\6.0\Java\
c.. Modify the class path and restart the server for the change to take
effect.
However, when I add my supporting classes to a jar in this directory Istill
get a class not found exception when I run the deployment tool.
Adding the classes to each EJB jar is redundant and introduces lots of
problems. How should I configure iPlanet so I only need to put my
supporting classes in one place?
Thanks,

Class not found error!!!

Hello,
I wrote a program that would read data from a file (present in one of my folders). I developed it as an applet and am able to see the result in appletviewer, but unable to see it in the browser(IE6-WIN2000). I did the HTMLConverter procedure and saw that it worked for all other files except this. The error it gives is:
load: rdbyte class not found
However, this class file is located in the same folder. And all the necessary methods like init() etc are present in my program.
Please help me!!!
Thanks
NS

Do you have used any other package then default package?
Look at the documentation and search something like this:
<applet>
<param name="code" value="yourClass.class">
<param name="codebase" value="classFileDirectory">
</applet>
Your applet must be signed to read or write file from your filesystem.

Optional Package class reference at server startup...gives class not found
