just a random guess...
I had a ton of issues with JBoss and jfreechart. JBoss uses a different classloader, and its internal versions of the jfreechart classes will be loaded before yours, causing all sorts of issues. Dig through the jboss directories and you'll find a different, older version of jfreechart of one of its classes. Remove them and you'll be in better shape.
Alternatively, look around the JBoss docs for how to disable/turn off the unified classloader for your app (its a directive in jboss-web.xml IIRC). This should make the classloader for your webapp perform to spec, getting rid of the class colission issues.

  • Unable to compile class for JSP

    Please can anyone help me to solve this.
    Actually,this is the condition.
    In my db,there is a table called UserPassword, which has 4
    fields(empNo,UserName,password,level). Now I want to do these things:
    When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
    1)To check the empNo,if it is already exist in the DB,
         if empNo =exist then display error.(record already exist)
         if empNo =notexist then do task 2).
    2)check the UserName,if it is already exist in the db,
         if UserName=exist then display error.(because it's a primary key)
         if UserName=notexist then do task 3).
    3)Create a new user account and save it to the db.
    To do these tasks,I never create a new objects for the tasks 1) and 2).
    only for task 3)create an object.
    Is it the right way?
    Here is the file CreateAcc.jsp
    <%@ page language="java" %>
    <%@ page import="core.UserAccManager" %>
    <%@ page import="data.UserPassword" %>
    <jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
    <jsp:setProperty name="UserAccManager" property="*"/>
    <jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
    <jsp:setProperty name="UserPassword" property="*"/>
    <%
    String nextPage ="MainForm.jsp";
    if(UserPassword.verifyEmpno()){
         if(UserPassword.verifyUsername()){
              if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
          }else{
               nextPage="UserNameExist.jsp";
          else{
              nextPage="UserAccError.jsp";

    <jsp:forward page="<%=nextPage%>"/>The directory structure:
    UserPassword.java- F:/Project/core/data/UserPassword.java
    UserAccManager.java - F:/Project/core/UserAccManager.java
    Now both are compiling.I put the class files into the TOMCAT,as follows.

    Are there any mistakes? If so tell me where is it and how to change them.Please help.

    I try it that way, but it don't compile.
    Error:core\data\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    core\data\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Then it compile well.I goto the directory to get the .class files.
    But there is only UserPassword.class inside the data folder. There is not
    UserAccManager.class in the core folder.
    Then I try this way,I put my 2 java files in to a new folder,
    F:\SystemName\com
    When I try it that way, but it don't compile.
    javac -classpath . -d . com\*.javaError:com\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    com\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Now both are compiling well.There was 2 class files.
    I put them in to the WEB-INF/classes/com directory.
    Start the server.But it gave errors:

  • Unable to compile class for JSP. apache-tomcat-6. What could be wrong?

    Hello, I am new to JSP and I am trying a very basic jsp and class file on Windows XP. I get the Unable to compile class for JSP.
    Steps that I have done:
    javac ch06_01.java , placed the ch06_01.class under
    C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes
    Then grabbed the ch06_02.jsp and placed it under
    C:\Apps\apache-tomcat-6.0.16\webapps\ch06\
    When I run it (by placing this into Explorer or Firefox URL
    http://localhost:8080/ch06/ch06_02.jsp) I get the error further
    below. Things I have done and made sure they are in place are:
    set up JAVA_HOME to C:\Apps\jdk1.6.0_06
    Using CATALINA_BASE: C:\Apps\apache-tomcat-6.0.16
    Using CATALINA_HOME: C:\Apps\apache-tomcat-6.0.16
    Using CATALINA_TMPDIR: C:\Apps\apache-tomcat-6.0.16\temp
    Using JRE_HOME: C:\Apps\jre1.6.0_06
    I did a google on the error and I found people saying to place the
    tools.jar from the jsk into the lib directory under CATALINA_HOME. But
    the examples still don't work. What step could I be missing? Your help is greatly
    appreciated.
    This is the simple jsp file:
    <%@ page import="ch06_01" %>
    <HTML>
    <HEAD>
    <TITLE>Using a JavaBean</TITLE>
    </HEAD>
    <BODY>

    <% ch06_01 messager = new ch06_01(); %>
    The message is: <%= messager.msg() %>
    </BODY>
    </HTML>
    this is the simple ch6_01 java file:

    return "Hello from JSP!";

    I just updated the directories of the variables to reflect the current status of my system.

    What is wrong is that you are using an "old" jsp tutorial :-)
    Since Java 1.4, JSPs have been unable to access classes in the "default" package.
    What you need to do:
    Put the java class ch06_01 in a package.
    Steps to do this
    - Edit ch06_01 and add the following to the very top of the file (without the quotes): "package mypackage;"
    - create a folder "mypackage"
    - move ch06_01.java into that folder
    - compile that class (now in the mypackage package)
    - place ch06_01.class under C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes\mypackage
    In your jsp:
    <%@ page import="mypackage.ch06_01" %>
    I would suggest using a more up-to-date tutorial that uses JSTL.
    Take a look at this [Apache Tomcat tutorial|http://www.coreservlets.com/Apache-Tomcat-Tutorial/index.html]

  • Tomcat 4.1 Bean error (Unable to compile class for JSP)

    Help,
    I am using Tomcat 4.1 with with JDK1.3.1_01. I have a JSP page in which I try to use a Bean, but I get the following error from Tomcat.
    The JSP page is very simple. I am using package names in the import statement. Code below.
    I've put the class files under
    <TOMCAT>\webapps\projectname\WEB-INF\classes under the appropriate packages. What else is missing? I can not figure out what I am doing wrong.

    ***************** END TOMCAT ERROR MESSAGE *********************

    Hi
    I am running my Tomcat apps (on a Windows dev machine) in an alternate location (ie. not default webapps). The same crap comes to me every time. Unable to install etc. I have tried every trick in the book regarding classpath settings etc.
    When I use 'javap' to check the classpath from any location on my machine, its works and javap returns the signature of my class.
    When I use it though Tomcat (with the import set to include the filename), it get the error. I have heard rumors that using JDK 1.3 in stead of 1.4 helps, but I just want it to work with 1.4 :)
    So if any of you can help me on this, please.
    PS. On my linux server it works just fine, as does every other thing on that machine ;)

  • Error:Unable to compile class for JSP

    Hi all,
    I am new at jsp,just started to learn a week ago :) Anyway I'm having troubles with using a compiled java class in jsp code.I use tomcat 4.1.31 and java 1.4.2.I have compiled the following programm and put the class into tomcats' webapps\ch06\WEB-INF\classes directory
    public class ch06_01
    public ch06_01()
    public String msg()
    return "Hello from JSP!";
    Then I have the following jsp file in the webapps\ch06 dir as well:
    <%@ page import="ch06_01" %>
    <HTML>
    <HEAD>
    <TITLE>Using a JavaBean</TITLE>
    </HEAD>
    <BODY>
    <H1>Using a JavaBean</H1>
    <% ch06_01 messager = new ch06_01(); %>
    The message is: <%= messager.msg() %>
    </BODY>
    </HTML>
    But when I try to ran the jsp page following error occures:
    org.apache.jasper.JasperException: Unable to compile class for JSP
    An error occurred at line: -1 in the jsp file: null
    Generated servlet error:

    Can anybody help me,please!I appreciate your help a lot!
    Thank you verry much!
    Best regards Daisy

    Its not a Tomcat issue per se, but a change in the J2SE.
    Its been the case since the release of Java 1.4, when they disabled access to the "default" package. Quite a few of the books written before Java1.4 was released are still around, and there are endless examples around the net that no longer work as a result of this change.

  • Unable to compile class for JSP: import ...

    Hi everybody!
    I've tried to change from Servlet to JSP. The Servlet used a package und compiled fine under NB 4.1.
    When the JSP is compiled on the Server (Sun Java System Application Server Platform Edition 8 2004Q4 Beta) the following error occurs:
    org.apache.jasper.JasperException: Unable to compile class for JSP
    Generated servlet error:
    [javac] D:\Programme\Sun\AppServer\domains\domain1\generated\jsp\j2ee-modules\NR_Java4Web1\org\apache\jsp\DisplayingDatabaseRecords_jsp.java:44: illegal start of expression
    [javac] import de.conus.util.DBUtil.*
    [javac] ^
    Do I have to place the classfile manually on the server?
    Thanks for your help,
    Michael

    All import-statements where of the same kind. I had to place trhe classfiles
    at the application server under lib\classes. Now it works
    Thanks

  • Unable to compile class for JSP.       package not found

    Hello folks,
    I was trying to build a simple web application using Eclipse IDE, tomcat 5.x server and ant to build and deploy the application.
    I referenced the following tutorial:

    }I read in one blog (actually - the only page which was returned by yahoo - so - this should be very rare error!!!) to try to use Sun server's verifier.bat - and - it reported 0 errors and 0 warning. Build was succesfull as well and also - deployment was without errors - but - above mentioned error appeared during the automatic compilation of jsp pages/servlet when newly deployed jsps are first accessed from remote browser.
    So - is it possible, please, to receive some advice - what to do further? I feel that my invoice.jsp page can be with errors, - however - the original welcomeJSF.jsp should be working without errors even the erronwous JFS jsp page is added to web application.
    Thans for any adice or hint in advance!!!

    OK - I have made 'clean and build main project' from NB menu and the deployed the resulting *.war and the error messages have disappeared... So - it seems to be bug...

  • First use of jsp and java bean and "Unable to compile class for JSP" error

    Hi,
    I am trying to create my first jsp + java bean and I get a basic error (but I have no clue what it depends on exactly). Tomcat seems to cannot find my class file in the path. Maybe it is because I did not create a web.xml file. Did I forgot to put a line in my jsp file to import my bean?
    Thank you very much for your help.
    Here is my error:
    An error occurred at line: 2 in the jsp file: /login.jsp
    Generated servlet error:
    [javac] Compiling 1 source file
    /usr/local/tomcat/jakarta-tomcat-5/build/work/Catalina/localhost/test/org/apache/jsp/login_jsp.java:43: cannot resolve symbol
    symbol : class CMBConnect
    location: class org.apache.jsp.login_jsp
    CMBConnect test = null;
    I only have this in my directory:
    test/login.jsp
    test/WEB-INF/classes/CMBConnect.java
    test/WEB-INF/classes/CMBConnect.class
    Do I need to declare another directory in classes to put my class file in it and package my bean differently?
    Here is my login.jsp:
    <%@ page errorPage="error.jsp" %>
    <jsp:useBean id="test" type="CMBConnect" scope="session" />
    <html>
    <head>
    <title>my test</title>
    </head>
    <body>
    <h3>Login information</h3>
    <b><%=session.getValue("customerinfo.message")%></b>
    <form> ....... </form>
    </body>
    </html>
    and here is my CMBConnect.java:
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.SQLException;
    public class CMBConnect
    public CMBConnect () { }
    public String openConnection(String id, String password) {
    String returnText = "";
    try {
    Connection con = null;
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    con = DriverManager.getConnection("jdbc:oracle:thin:@myserver.abc.com:1521:TEST", id, password);
    if(con.isClosed())
    returnText = "Cannot connect to Oracle server using TCP/IP...";
    else
    returnText = "Connection successful";
    } catch (Exception e) { returnText = returnText + e; }
    return returnText;
    Thanks again!

    Hi,
    I am using J2EE SDK 1.4 Server and deployed a Stateless Session Bean and used a JSP page as Web Deployment component. When I deploy the application no error is given but when I access application using the given web context name the following error is displayed on the browser.
    type Exception report
    message
    description The server encountered an internal error () that prevented
    it from fulfilling this request.
    exception
    org.apache.jasper.JasperException: Unable to compile class for JSP
    No Java compiler was found to compile the generated source for the JSP.
    This can usually be solved by copying manually
    $JAVA_HOME/lib/tools.jar from the JDK
    to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
    If using an alternate Java compiler, please check its installation and
    access path.

    Can anyone tell me why this error could be generated? I've given the JAVA_HOME environment variable value as C:\Sun\AppServer\jdk and J2EE_HOME variable value as C:\Sun\AppServer.
