Listener class not found which is declared in the Connector project.

Hi friends,
I have a problem, I have created a new J2ee connector project in eclipse
and created the classes listener,activatioinspec,resource adapter and worker with the name JCA1. I have created another Message driven bean project with name MDB1.Since iam using EJB2.1, I have not implemented MessageListener instead of that i have implemented the
listener class which is created in the JCA1 Connector project.In the MDB class i have imported that listener class implemented.
Iam using application server Jonas, i have declared in ra.xml message listener type, In the MDB1 ejbs ejb-jar also declared messaging type.
While deploying the MDB1 jonas log says the class listener declared in the JCA1 not found , can any one suggest what is the problem ??, Listerner class is declared in JCA1 Connector.
Thanks
Rafel

Did you read the tutorial from Creator?

Main-class not found error while clicking on the jar

I have a created a jar �FinARM.jar� for my swing application using eclipse.
Clicking on this jar, it is giving the problem main-class not found.
It contains the MANIFEST.MF file, with entry Main-Class: FinAlignTest for the main class.
FinAlignTest is my main class.
I have a similar jar created with a small swing application (Single file) clicking on it can open the swing application.
It is also attached above.

Hi ,
My Apllication runs with out any warnings or errors. But when i create a jar file using eclipse it is giving this problem.
When i double click on the jar file i am getting this problem. MANIFEST.MF entry contains the main method entry.
I have created another jar (Which contains a simple java file, swing application) from eclipse export option.
It works fine on click.
But jar FinARM.jar contains 5 files (Swing app), which even fetch some data from the database.
My jar is placein the same machine where it can fetch data from DB
Can u plese tell me whats the problem.

I know we can avoid to the error by adding the jar file containing this class to the class path. But is there any other way?
Best Regards,

You could double-check in the JMS newsgroup, but I'm pretty sure that a statically configured listener like this would have to be in the classpath.
If possible, I'd encourage you to consider using a MDB instead. That could be in your EAR file instead.

Chainsaw 1.3 error on socket listening (class not found exception)

Hi,
I'm not sure that's the right place to post on this subject, but I can't find a better place on forum's topics.
So I've got following problem :
I'm using chainsaw 1.3 with java web start. Before september, it was working very well.
I'm using a log4j.properties, and that the sample for socket appender :
log4j.appender.socket=org.apache.log4j.net.SocketAppender
log4j.appender.socket.remoteHost=localhost
log4j.appender.socket.port=4445
log4j.appender.socket.locationInfo=true
Few days ago, chainsaw has updated itself and since I got everytime this lone and pretty ugly message on chainsaw :

My console and file appenders are still working on, but I'm not very comfortable to read them (they are pretty messy!)
So if somebody could help me to fix that, or even give me advice to set up another kind of receiver, I will thanx him a lot. (I am figthing with log4j xml setup file, but I can't figure how to set up something working with chainsaw...)
Bye

I'm one of the Chainsaw developers...
LocationInfo is temporarily broken. In the meantime, there are two workarounds:
This workaround won't give you locationInfo in Chainsaw but will load the events:
1. Set the socketappender as the first appender in the list in the log4j.properties file - example:
log4j.rootLogger=debug, stdout, Socket, Rollingfile
reason this works: socketappender defaults to locationinfo=false, and rollingfile was using %L pattern (locationinfo), which modifies the logging event that is sent over the socket. Send the event over the socket prior to using the %L locationinfo pattern in the fileappender.
This workaround will give you location info in Chainsaw:
2. Don't use a socketappender-instead, have Chainsaw parse and 'tail' the file using logFilePatternReceiver.
As long as the location info pattern is part of your pattern layout in your file appender config, Chainsaw will display the location info (location info isn't being serialized in this case).
Here's an example logFilePatternReceiver config for use with Chainsaw (modify the param values based on your fileappender config):
<plugin name="logFileReceiver" class="org.apache.log4j.varia.LogFilePatternReceiver">
<param name="fileURL" value="file:///c:/downloads/log4j/sample.log" />
<param name="timestampFormat" value="yyyyMMddHHmmssSSS"/>
<param name="logFormat" value="TIMESTAMP LEVEL(FILE:LINE)#CLASS,LOGGER THREAD!MESSAGE"/>
<param name="name" value="logfileReceiver" />
<param name="tailing" value="true" />
</plugin>
Here's the source/javadoc for logFilePatternReceiver describing the params and keywords supported when defining the logFormat:
http://cvs.apache.org/viewcvs.cgi/logging-log4j/src/java/org/apache/log4j/varia/LogFilePatternReceiver.java?rev=1.19&view=auto

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.
Regards,
Johnson

news:9s6h33$[email protected]..
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,
Mark

SQL Driver class not found

Hi,
Wonder if anyone can help. I have developed our own version of the logon page, and in the JSP I read a java database using the recommended driver class com.sap.portals.jdbc.sqlserver.SQLServerDriver which can be found in p9sqlserver.jar. This worked fine.
After a recent upgrade from SP12 to SP14 the jar in which this class can be found has moved and I now get at class not found exception.
Looking at the difference between the two versions of the portal comparing the difference of the locations of the jar:
SP14 - //Server0/bin/ext/jdbcdrivers/p9sqlserver.jar
SP12 - /../Server0/bin/ext/datadirect/p9sqlserver.jar
Does anyone know how I can get my component to find the jar file ?
Thanks
Phil

Hi,
i have the same - a custom logon Page with SQL-Connect where the driver class cant be found anymore after upgrading to Sap Netweaver Portal 2004s from (EP 6).
I tried to register the driver (//Server0/bin/ext/jdbcdrivers) like advised under:
http://help.sap.com/saphelp_nw04/helpdata/en/c7/641f44be9f1e4ebbe807cfbad61d44/frameset.htm
but that did not work for me.
Did any of you ever solve this poblem.
THX & regards

Error : class not found exception : com.mysql.jdbc.driver in Eclipse Tool

Hi
I have impoted project file in eclipse in new machine using option import from existing workbence . When i stat to debug this project ,
i am getting error as class not found exception : com.mysql.jdbc.driver . my project folder already consist of mysql .jar file in /web appls/web-inf folder.
Application is running successfully in other machine from where i took the application file. As this error appeared I also added jar file into project path as Project ---->properties-- build java path---libraries----add external jar file.
kindly hep me.

Sounds like an eclipse question - not a JDBC one.
But since eclipse is telling you it can't find it then it means it is not in the eclipse path. So you must add it. (The fact that it is somewhere is irrelevant - all that matters is it is not in the class path.)

Class not found, Jdk1.4 matters?

Why drivers can't be loaded for this machine? Make me strugge for many hours already.
1)
Version j2sdk-1_4_2_07- (Java 2 se, 1.4)
Environment: Windows XP
I keep receiving "Class not found" exception error when running the following simple piece of codes for testing. (No complint When compiling). The code simply reads:
try {
System.out.println("driver loading test step 0 !!!....");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("driver loaded 1 !!!....");
System.exit(0);
catch (ClassNotFoundException ee) {
System.out.println("Clss not found\n" + ee.getMessage());
My other simple java codes got compiled and run ok in the same enironment.
2)
I then replaced the sun jdcd-odbc bridge driver in the test with a jdbc driver (for Sql server) downloaded from DataDirect.
That is: by replacing the one line above with the following. But it gives me classNot found Exception too. I don't think it has to do with classpath as I add it in the java command line already
Class.forName("com.ddtek.jdbc.sqlserver.SQLServerDriver");
3) I moved the codes to run in my old PC (Windows NT 4) with jdk1.3, the codes are compiled and run WITHOUT Class not found Exception.
I had more than a year experience in developing Java codes (though not recently) but what I experience now is so wierd to me. What's wrong with jdk1.4 or what's wrong with this XP machine?
Thanks.

99.999% of the time, something is wrong with your classpath at execution time, or with the classname you put in your code (those class names do look right though). That the same code works on another machine almost certainly means that something has set the classpath in the environment on one machine and not the other.
.001 percent of the time, something is wrong with your machine, such as a corrupted file system or OS. If so, reformat your drive, and reinstall everything. However, always, there will be other symptoms of problems (mystery crashes, disappearing files, etc.), so don't waste your time doing this unless your computer is already flaky.
Most likely, you just don't know how to set the classpath for execution. For that, use Google.

WLS 7 SSL class not found error

Actually, I got the same error message to start the Node Manager. However, I don't
have the RSA license at this moment. How can it make the WL to use com.certicom.net.ssl.CerticomContextWrapper
instead of com.rsa.ssl.WeblogicContextWrapper?
Thanks,
Victor

I had discovered that when I typed "java program name" the java was running from /usr/bin a non-ssl enabled java installation. There was an SSL enabled version under another path on this box and it ran my code fine.

Installation problem on redhat 6.0, class not found

Does anyone know what this means? and what do i have to do?

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 in applet using 2 jar files

I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
The HTML I am using to call the applet is:
<applet code="AMJApp.class"
codebase="http://www.interactived.com/JMTalpha"
archive="AMJ014.jar,plugin.jar"
width="500"height="500"
MAYSCRIPT style="border-width:0;"
name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:
load: class NervousText.class not found.

Class not Found when accessing Proxy class from backing bean in VC.

Hi All,
I'm attempting to access a class of a webservice(generated as a proxy) within my ADF application and invoke the method within a backing bean of the View Controller(bean scope : backing bean). The proxy has generated an ObjectFactory class among other classes. When I access this Object factory class from within the backing bean, the application throws a Class not found error.
I don't know where the error lies since I've declared the View Controller of the ADF application dependent on the Proxy and I've imported the class and accessing it within a backing bean. How would you suggest I approach resolveing this.
JDev : 1.1.1.4
Thank you.
Regards
PP.

Hello Arun,
Thank you for suggesting a Data control, but my requirement isn't to drag and drop the method as a button. It's more of a behind the scnes updating data via a database adapter requirement.
I've resolved the issue. turns out, my deployment archive didn't include the proxy.jpr. Once included it works likea charm.
Thanks
PP.
