Error in Class not found

When i try to connect SQl 2000 database using JDBC, it gives an error indicating "java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver"
I alredy set the CLASSPATH correctly & my JDBC driver also installed into my computer.
Pls any1 who can help me to solve this...........
Thankz

If you run the program and it doesn't give you a ClassNotFound or NoClassDefFound exception then you've got the classpath set right.
The trick is knowing what it should be set to. For JAR files, your classpath must include the JAR file itself, not the directory containing the JAR file.
Depending upon how you're running the application the classpath may be provided on the command line, set as an environment variable, or placed in a configuration file. Without knowing more about your application it's impossible to advise you further.

  • 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.)

    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).

    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,

    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.

    As

    But weblogic complained that the class is not found.

  • HELP!! Nokia's API classes not found with j2me WTK

    I setup j2me WTK, jdk1.4.2 and also Nokia's SDK (Series_60_MIDP_SDK_for_Symbian_OS_v_1_2_1) on my Win NT 4.0 machine.
    J2ME samples (shipped with it) are working fine with ktoolbar. but when i try to build & run nokia samples, they are always giving error "FullCanvas class not found" and "package com.nokia.lcd.ui.* not found". I am sure it is the problem of placement of classes of nokia at correct place inside j2me's WTK. However, i followed the guidelines to install symbian sdk inside wtk401\wtklib\devices folder (as per instructions of forum nokia). But i am still not able to get it running. Any expert suggestions, then plz respond me , i am in urgent need to solve this issue!!!! plz help me!!!!

    Hi,
    Maybe I'm being thick but I can't get this work. I've tried zipping the com/nokia stuff into the midpapi.zip. And I've tried just replacing midapi.zip with classes.zip from the nokia emulator. But it still says:
    "package nokia.mid.ui does not exist
    import nokia.mid.ui.*;"
    I'm using ktoolbar 1.04.
    Many thanks!
    CP
    Hey, thanks for the great tip. Was also using
    KToolbar because it runs faster on my slow laptop than
    Sun One studio.
    With the later version of WTK, the paths
    C:\...\WTK21\lib contains 2 files, midpapi20.zip and
    midpapi10.zip
    The later contains classes for compiling to MIDP1.0
    standard. I think most people use this. Replace it
    the class.zip in
    C:\Nokia\Devices\Nokia_7210_MIDP_SDK_v1_0\lib if
    you're using the same SDK as I am, and don't forget to
    rename it.
    Cheers.

    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.

  • "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.

    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!!!

    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?

  • 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

    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.
