Java.lang.NoClassDefFoundError: jxl/Workbook

Hi Friends,
I have created an DC application where i read data from excel.For this i have used jxl.jar.I have created External Library DC and add this jar to it.
Now i have added the External Library DC to the actual application.
I dont get any compilation error.But when i execute it im getting the following error.

select jars tab-->add jxl.jar
right click on proj build library archive , deploy the sda file

Java.lang.NoClassDefFoundError: jxl/format/CellFormat

hi Experts,
i m trying Excel export and import functionality for this i m using jxl.jar ,but when i m deploying my application i m getting java.lang.NoClassDefFoundError: jxl/format/CellFormat
how to resolve this problem.

Hi,
it depends whether you are using JDI or not. If you use JDI, you only have to create an External Library DC and add the jxl.jar per Drap&Drop in Navigation panel to the DC. Add the file also to the public part. In the Web Dynpro DC add the External Library DC as used DC and deploy both DCs on the server.
The only error you can make is to deploy the components using "Deploy new archive and run..." -> this command won't deploy the jar and you have the same result as now. You have do build & deploy it step-by-step (Development Component -> Build..., Development Component -> Deploy).
If you don't use JDI, perform like described by Lakshmi.

The jar for org/apache/commons/httpclient/HttpClient is in my web_inf/lib dir as it always has been. It wouldn't have worked on restart if it wasn't.
So, the question is... is there some bug in the Tomcat and Java combination I've got that caused this? If not, then what happened? Should I up the logging level to warnings? Should I move the jars I'm using into the tomcat lib dir? Any help would be appreciated by this early java learner.
Thanks,

Could this be a situation where load played a factor? Just another thought I had...

Hi Friends
I am stuck in this typical Junit problem for a copule of days but still not able to find any solution for it.The problem is as below.
I have written Junit test case for 1 method that has been added in the session bean. the code is as below.
public void testfindResponses() {
               ClientManager cMgr = null;
               Collection retvalue= new ArrayList();
               try {
               System.out.println("Before");
               cMgr = EJBHomeUtilities.getClientManagerHome().create();
               System.out.println("After" + cMgr.toString());
          //     retvalue=cMgr.findSurveyResponses(clientPk,startTime,endTime);
               }catch (RemoteException e) {
               //logger.error(e.getMessage());
               throw new EJBException(e.getMessage());
               } catch (CreateException e) {
               // logger.error(e.getMessage());
               throw new EJBException(e.getMessage());
               } finally {
               EJBHomeUtilities.removeSessionBean(cMgr);
          //return retvalue;

The remote reference that i get seems to not work atall.i tried to put debug statements to see if i am getting the remote reference,but the control seems to not go there itself.
The same method if i write for another session bean it is working fine without any errors.
Please let me know whats wrong here as i am stuck up with this issue for a long time .waiting for positive replies from your side.
Thanks & Regards

I also came across this error . . . the exception message seemed to indicate a problem in the HTML file. In mine, I had the HEIGHT and WIDTH attributes set to 100% -- something that is nonsensical outside of a browser context. I changed those values to some number of pixels (800 and 600, say), and the exception did not reoccur. I suggest you try the same.

I don't have any idea to offer on what the problem is. However, here are some suggestions:
Perhaps you can provide an example of your code and/or a more through description of what it does so someone might see something wrong with the code.
I assume you print out the entire stack trace using somthing like this, so you can get the entire stack trace:
} catch (Exception e) {
e.printStackTrace();
and not something like this:
System.out.println( e.getMessage());
You can also consider peppering your code with System.out.println() statements (or write to the log file) to get a better understanding of whats going on and where it crashes.
What is jgps.RTI.jar? Is that a jar file you created or a vendor jar file? If its a vendor jar file, you might research their web site on how to use it.

Java.lang.NoClassDefFoundError: javax/mail/Service

Hi,
Happy New Year Everyone! Sadly, it's not that happy for me right now, I'm trying to write a mail app using JavaMail, but I'm getting a NoClassDefFoundError when I run the program.... The program compiles fine, it only crashes when I run the program. Does anyone have any ideas why that's happenning? I compile the program using javac -classpath .:mail.jar *.java and I'm working on a Unix Box. Any help anyone can provide is greatly appreciated!
The error message I received is pasted below (I left out the stack trace to make reading easier).
Exception occurred during event dispatching:
java.lang.NoClassDefFoundError: javax/mail/Service
[Stack Trace]
Thanks in Advance!
Juivette

Read the directions that came with the javamail API...it tells you the OTHER API you need. Also, word of advice....I un jar'd and re-jar'd all the classes from BOTH API's in one file...makes life easier.

Signed Applet gives "java.lang.NoClassDefFoundError" message

I am using a Signed Applet to access resources on the disk and as well as to write on to the disk.
My Applet class "Applet.class" is bundled along with other required jar files(SignedA.jar , SignedB.jar) into a single jar file "SignedApplet.jar". The external jar files have also been signed using the same key.
When I run this applet, it gives an error " java.lang.NoClassDefFoundError" for the classes that Applet.class tries to access in the external jar file SignedA.jar
Please help

You need to set your classpath correctly. Search the forums for NoClassDefFoundError and you will find hundreds of posts on this topic. Many of them have answers explaining how to set your classpath.

I doubt that the error is caused by " java.io.* " which is not included in MIDP so that my program cannot run in WTK21.. is that true?
if yes, what can I do with it because I have to run it in WTK21 for demonstration. thx!!!!!

Please HELP me with installation - java.lang.noclassdeffounderror:

Please Help! For school we need to install JAVA. I installed JDK 5.0 and id did not work. I got exception in thread "main" java.lang.noclassdeffounderror: hello. I was using Texpad to write, compile, and run it. In short I deleted all JAVA 5.0 using My Computer program removal. I installed JAVA 1.4..2_10 and I am still getting that same error. I want the JAVA 1.4..2_10 to be installed and not JAVA.5.0.
My System Variable CLASSPATH still shows C:\Program Files\Java\jre1.5.0_03\lib\ext\QTJava.zip. My System Variable PATH has nothing as far as JAVA in it. MY PATHEXT has JS and JSE amoung other things in it. My System Variable QTJAVA still has Files\Java\jre1.5.0_03\lib\ext\QTJava.zip in it.
Please tell me step-by-step how I can fix this. I never updated these variables before. What do I need to type and where? What do I need to get rid of or change?
PLEASE HELP!
Thanks,
Jim

I left my System variable classpath --> C:\Program Files\Java\jre1.5.0_03\lib\ext\QTJava.zip I left my QT JAVA --> C:\Program Files\Java\jre1.5.0_03\lib\ext\QTJava.zip I added Path --> ;C:\j2sdk1.4.2_10\bin and then restarted my computer. I added hello file in C:\j2sdk1.4.2_10\bin and tried to compile it under a new name and it would not compile. it gave me the error below. I was able to compile other java program in my other folder in a different directory. I am still getting the same error messages/ Anything else I should try? IS there anyplace or person I can call who would come and fix this? Something is wrong. This should not be giving me this much trouble. All The Java directions on other websites tell me to do different things. I am so confused... please help.
I get this during the compilenow:

Java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver

I am trying to connect from a servlet running in Tomcat on my desktop to an instance of Personal Oracle9i running on my desktop. I am gettiung NoClassDefFoundError. The code compiles.
I know it is a path issue but I am at a loss to figure out where. Tomcat does not find the driver however it is in my machines path.
Running following:
j2sdk1.4.1_02
Personal Oracle 9.2
Tomcat 4.1.29
Windows XP
I have added the location of Classes12.zip to the class path: .;c:\Sun\AppServer\lib\j2ee.jar;c:\Sun\AppServer\lib\j2ee-svc.jar;d:\oracle\ora92\jdbc\lib\classes12.zip;
The "root cause" of error is:
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
     at OOP.OracleConnectionDemo.doPost(OracleConnectionDemo.java:34)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
The code is as follows:
import java.sql.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import oracle.jdbc.OracleDriver;
//import oracle.jdbc.driver.*; //did not work either
public class OracleConnectionDemo extends HttpServlet {
     public void doPost(HttpServletRequest req, HttpServletResponse resp)
          throws ServletException, IOException{
          Connection con = null;
          // Load the Oracle JDBC driver
          try{
               //two versions did not work
               //DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver);
          DriverManager.registerDriver(new OracleDriver());
     con = DriverManager.getConnection
               ("jdbc:oracle:thin:@micron.1521:MCAP","scott","scott");
          catch (SQLException e){
          catch (Exception e){
          finally{
               try{
                    if (con != null)
               con.close();
          catch(SQLException ignored){
          }//finally
}

What you should be realizing is that Tomcat doesn't give a hoot about your system CLASSPATH. It totally ignores it. You really shouldn't even have one, because IDEs and app servers don't even take it into account. Get rid of it.
You're making lots of mistakes here:
(1) The Tomcat docs explicitly state that it won't look inside ZIP files. Change it to a JAR file.
(2) You're using JDK 1.4.1 and classes12.zip? You realize, of course, that there's an ojdbc14.jar available for download from Oracle. Go get it.
(3) Put the JDBC JAR in the WEB-INF/lib directory of your Web app. If you don't have one, you're not deploying your Web app properly.
(4) You've got Java code with empty catch blocks? That's one of the most foolish things a person can do. If an exception's thrown you'll never know it. For goodness sake, at least print the stack trace.
(5) Why do you have those Oracle imports? That ties your code to Oracle. The design of the java.sql package lets you use interfaces. Why don't you write JDBC the way it was meant to be written?
(6) Why aren't you setting up a JNDI data source?
