JavaBean class invalid error

Hello there,
I am new to jsp development and am having problems using javabeans. I get a class invalid error. I have created a simple example that works fine without the useBean line (there Bean doesn't do anything in the example). I have looked over earlier posts in which others have discussed this same problem (http://onesearch.sun.com/search/clickthru?qt=useBean+invalid&url=http%3A%2F%2Fforum.java.sun.com%2Fthread.jspa%3FforumID%3D45%26threadID%3D567258&pathInfo=%2Fonesearch%2Findex.jsp&hitNum=1&col=developer-forums), but I none of the proposed fixes has worked for me. I hope that someone will see something that I'm missing. Below are the files that make up the example
// userInput.jsp
  <html>
    <body>
      <h3>UserInput Form</h3>
      <form name="inputForm" action="userOutput02.jsp" method="post">
        <input type="text" name="userName">
        <input type="submit" name="submit" value="GO">
      </form>
    </body>
  </html>
// userOutput02.jsp
  <jsp:useBean id="userInfo" scope="session" class="beans.User" />
  <html>
    <body>
      <h3>User Output</h3>
      Hello <%=request.getParameter("userName")%><br>
      <a href="userInput.jsp">Enter another name</a>
    </body>
  </html>
// User.java
  package beans;
  public class User {
    protected String name;
    public User () {}
    public String getName () {
      return name;
    public void setName (String userName) {
      name = userName;
  }// Location of User.class
<%webApplicationRoot%>/WEB-INF/classes/beans
// Error Message when userOutput02.jsp is loaded
org.apache.jasper.JasperException: /jsp/userOutput02.jsp(1,1) The value for the useBean class attribute beans.User is invalid.

Well, I doubt this is your problem, since I don't see you trying to set anything, but the form field should really match your setter.
If the setter is setName, the form field should be named "name" (though I'd switch everything to userName instead of name, myself, as name tends to be a reserved word in various applications and languages).
Other than that, are you using Tomcat, weblogic, or...?

    Hi,
      Please try to re-generate the adapter object (ZDNL_CUST_CND) services using trx.
    SMOGGEN
    . After this, try re-running the load.
    I assume that your CRM inbound mapping module are correctly coded. If the problem persists, try de-registering the R3AD_CONDITIONS inbound queue using trx.
    SMQR
    and then debugging the inbound queue from the same trx. after re-starting the load.
    Reward if this helps!

    <jsp:useBean id="sampl" class="beancode" scope="page" />
    <jsp:setProperty name="sampl"; property="*" />
    and in the class attribute specify the fully qualified class name without the extension

  • Class format error: Invalid constant pool tag found

    I am simply attempting to create an instance of an object and I get Class format error: Invalid constant pool tag found. Does anyone know what this means and how to fix it?
    Thanks.

    If you're compiling with J2SDK 1.4 or higher, you need to use "-target 1.1" on the javac command line.
    Also make sure you're not using any float constants such as 1.0 in your code.

  • Cannot find JavaBean class?

    Created JSP program that calls a javabean but for some reason it cannot find the javabean class. I moved the NonConfBean.class and NonConfBean.java modules to the directory: C:\jakarta-tomcat-4.0.3\webapps\examples\WEB-INF\classes. Also, I modified my CLASSPATH to the following: .;C:\j2sdk1.4.0\lib;C:\jakarta-tomcat-4.0.3\webapps\examples\WEB-INF\classes.
    Here is the JSP:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

    <%@ page import="accsp.application.*"%>
    <head>

    <body>
    <jsp:useBean id="accapp"

                                  scope="request" />
    <jsp:setProperty name="accapp" property="*"/>
    <BR>
    <% accapp.updateDatabase(); %>
    <jsp:forward page="NonconfPresentation.jsp" />

    Why is this happening?

    Yes I have put NonConfBean.class in the following directories just to make sure I am covering all bases:
    1. C:\accsp\application
    2. C:\j2sdk1.4.0\accsp\application

    And here is the JSP that tries to do the import:

  • HELP! Beginning JSP with JavaBean Class

    First of all, I'm using jdk1.4 beta and Jakarta's tomcat version 4.0.1 release build.
    Hello. I desparately need help. I have a JavaBean class ("CarBean.class") saved in %catalina_home%\webapps\root\myapp\web-inf\classes\com\wrox\cars\CarBean.class
    I also have a jsp page saved as carpage.jsp in %catalina_home%\webapps\root\myapp\
    So when I point my browser to http://localhost:8080/myapp/carpage.jsp, I get an internal server error. It appears it can't find the JavaBean class for some reason. I'm pretty sure I have my envionment variables set up right. I can get it to work, if I save the JavaBean class in c:\jdk1.4\jre\class\com\wrox\cars
    Here's my JavaBean class source file:
    package com.wrox.cars;
    import java.io.Serializable;
    public class CarBean implements Serializable {
    public CarBean() {
    private String make = "Ford";
    public String getMake() {
    return make;
    public void setMake(String make) {
    this.make = make;
    and here's my jsp page:
    <html>
    <head>
    <title>Using a JavaBean</title>
    </head>
    <body>
    <h2>Using a JavaBean</h2>
    <% com.wrox.cars.CarBean myCar = new com.wrox.cars.CarBean(); %>
    I own a <%= myCar.getMake() %>
    <% myCar.setMake("Ferrari"); %>
    Now I own a <%= myCar.getMake() %>
    </body>
    </html>
    I'm not new to java, just JSP. I just don't know why I can't get the jsp to locate the JavaBean class. I remember I used to have an older version of Tomcat and I recall not having any problems. It seems the Tomcat 4.XX is somewhat significantly different than previous versions. Perhaps I configured my Tomcat wrong? Help would be greatly appreciated. Thanks.

    hi
    i am not using Tomcat server but as i worked in JWS you have to import the bean class from jsp files.
    so the first code in jsp file will be like this
    <%@ page import = "CarBean">
    becoz JWS cant automatically find the bean class we have to explicitly import bean.but i dont know if tomcat finds
    bean or one have to import.
    hope this will help u.

  • Assistance needed regarding a Class Definition Error:

    I've checked online tutorials, asked friends, tried other forums, IRC, online contacts, and NO ONE can help me at this. I've been stuck on it for hours, and I'm beyond the point of frustration, as I'm about 98% complete without this error. I get it when I try to access a file from the command prompt:
    Exception in thread "main" java.lang.NoClassDefFoundError: MiniTriangle
    Everyone tells me it's a Class Definition error. While this is good to know, no one seems to know how to fix it. So I'm here hoping someone knows an answer which could work for this. I sincerely thank you all for your help in advance!

    This will likely be nonsense, lol
    Well..I compiled it in Jcreator, 2 files packed together:
    package myprojects.minitriangle;
    The java files are in the C:\java directory, but they're separate from the compiler since I couldn't get there with the command prompt (Invalid folder name)

  • Class invalid for deserialization

    I have got a very simple Session bean. Now I am trying to call a class from this bean with the following error:
    class invalid for deserialization
    Not sure about the detail about the error but I tried doing lots of things with no success .. Please help!
    I have a class (see below) is being called by EJB as showns ..
    Row[] arrSort = new Row[marrRows.size()];
    arrSort = (Row[]) marrRows.toArray(arrSort);
    Arrays.sort(arrSort, new RowComparator());
    ArrayList al = new ArrayList(Arrays.asList(arrSort));
    ----------------------- class source ------------------------
    package org.uabhs.svcs.pagination.impl;
    import java.io.IOException;
    import java.io.Serializable;
    public class Row implements Serializable {
    public Object[] columns;
    public int[] columnSortOrder;
    public Row(int[] sortOrder) {
    columnSortOrder = sortOrder;
    public String toString() {
    String sReturn = "";
    for (int i = 0; i < columns.length; i++) {
    try {
    sReturn += (columns.toString() + "|");
    } catch (Exception e) {
    sReturn += "|";
    return sReturn;

    The class file was serialized when it was Serializable and it has now been modified to beExternalizable, or vice versa, or it has now been modified to be neither Serializable nor Externalizable.
    Leave it alone.
    Read the Versioning section of the Serialization Specification before modifying any classes which have been serialized to a permanent store, e.g. a file or a database. You can do some things, provided you keep the serialVersionUID constant, but any of the changes described are out, especially the last above, which is plain unreasonable.

  • Error building project using kXML2 - "Class loading error: Wrong name"

    Hi,
    I'm testing the XML-Parser KXML2 and downloaded the latest package, but the minimal version (kxml2-min.zip). I put this file into the directory "%j2mewtk%\apps\KxmlTest\lib" and wrote the lines
    import org.kxml2.io.*;
    import org.xmlpull.v1.*;
    When I try to build the project with the Wireless Toolkit (v1.04) it spits out the following error:
    Error preverifying class kxml2.io.KXmlParser
    Class loading error: Wrong name
    com.sun.kvem.ktools.ExecutionException: Preverifier returned 1
    Build failed
    I also tried the full package "kxml2.zip" but the same error occurs.
    How can I get rid of this? Thanks in advance!

    Okay, finally worked it out (hopefully). I unpacked the archive to a directory (say "%J2MEWTK%\apps\KxmlTest\tmpclasses") and then preverified them "manually":
    %J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.kxml2.io.KXmlParser
    %J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.xmlpull.v1.XmlPullParser
    %J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.xmlpull.v1.XmlPullParserException
    Then I packed them again to a jar-file:
    %J2SDK%\bin\jar.exe -cvf kxml2-min.jar %J2MEWTK%\apps\KxmlTest\tmpclasses\output\.
    That was all!

  • Class based error handling

    Hi evrybody,

      Rainer

    Hi Rainer,
    if you already have a regulation for class names, just replace CL by CX and apply them accordingly.
    For example, if your classes are named ZCL_... or YCL_..., your exception classes will be named ZCX... or YCX_..., respectively.
    See T100 message OO 145 for the details. Here is the German version:
    +Kurztext
    Klassenname &1 ist für den gewählten Klassentyp nicht zulässig
    Diagnose
    Namenskonvention für Klassen :
    Für eine persistente Klasse ist der Präfix 'CL_' bzw. Namensraum+Präfix 'CL_' ( z.B. 'ZCL' oder '/NAMESPACE/CL_' ) vorgeschrieben.
    Für eine Exceptionklasse ist der Präfix 'CX_' bzw. NamensraumPräfix 'CX_' ( z.B. 'ZCX' oder '/NAMESPACE/CX_' ) vorgeschrieben.
