Using java classes in jsp

hi everybody
I'm using Apache Tomcat 5.5.7 and I want to develop very very simple jsp-files.
I have a java class file called MyClass.
When I start the jsp file with the code line
MyClass class = new MyClass();
I get this error: MyClass cannot be resolved or is not a type
As I know the hierachy must be the following:
ProjectRoot/WEB-INF/classes/MyClass.class
ProjectRoot/start.jsp
In the java class the Constructor is empty... so I cannot see why this should make a problem. I also tried to put the class file into a package and import the package. I had the same error then.
I read something about the web.xml file which should be in the WEB-INF directory.
will this help me... and if yes, what do I need to write into it?
If I did any mistake I would be happy if somebody could give me a hint.
Cheers
alex

1 - The class needs to be in a package. eg com.mypackage.MyClass. This file lives in /WEB-INF/classes/com/mypackage/MyClass.class
2 - in your jsp you include the line
<%@ page import="com.mypackage.MyClass" %>
<%
MyClass myClass = new MyClass();
%>
3 - Also note that "class" is a reserved word in java, and can not be used as a variable identifier.
4 - Yes you most probably should have a web.xml file in the WEB-INF directory.
Look under the webbapps/ROOT/WEB-INF for a basic example.

  • Using java class from JSP page

    I have a class that connects to the database and return the result in form of array of objects, now I wrote a tester and I was able to print the result on the console but when it came to JSP how can I use this class I am a bit confused, how can I declare an array of objects and save the result that comes from the class method
    note: my class is not a bean it is a service class that contain methods to retreive different information from the database.
    I would apritiate any help but please make it in sequence for example declaring an array to hold the result then call the method that returns the array of objects..etc
    please help, I am really confused and don't know what to write
    thank you

    You can access a class in the same way as a bean, after all a bean is just a class that follows a set of rules.
    You need to put your classes in packages to access them.
    I have 2 packages, params and DTO. I set the class that returns the Data Transfer Object, or array of objects up as I would a bean
    <jsp:useBean id="DTO" scope="request" class="params.DTO" />
    I think you skip the above declaration and access it directly in code using
    params.DTO();
    but setting it up as I would a bean allows me to simply use
    DTO();
    DTO is the class that passes back the array of objects.
    Objects themselves I have in a seperate package, also called DTO (sorry if this is confusing, made sense at the time :-) ) You dont need them in seperate packages, just helped me keep DTO objects seperate from business logic classes......
    Now before I use params.DTO() I declare a variable of the Object type DTO() returns
    <%! DTO.workSheet[] ws; %>
    So, ws is the object type that will be returned by params.DTO()
    Then to get my array of objects back from params.DTO() :-
    ws = DTO.workSheet(day);
    or if you dont like the bean declaration
    ws = params.DTO.workSheet(day);
    You need to put your packages under WEB-INF/Classes when using Tomcat
    So I have
    Tomcat 5.0\webapps\myApplication\WEB-INF\classes\params
    Tomcat 5.0\webapps\myApplication\WEB-INF\classes\DTO
    Under which reside the classes

  • How to use java class in jsp page of JSPProvider?

    Hello everybody.
    I created simple JSPProvider channel with portal amconsole and named it "jspprov1". Then I created "jspprov"1 directory under "/ets/opt/SUNWps/desktop/sampleportal". I put "index.jsp" in it. And it worked until I add this line into "index.jsp": <% @page import="jspprov1package.aclass1" %>. Then I created directory "jspprov1package" under "/ets/opt/SUNWps/desktop/classes" and put "aclass1.class" into it and into "/ets/opt/SUNWps/desktop/classes" itself. I created "aclass1.class" on the other machine (with no installed portal) in j2sdk1.4.1_02: "javac aclass1.java". The text of this class is simple:
    "package jspprov1package;
    public class aclass1{
    public int int_field = 10;
    But the page still don't work. It writes on the portal desktop "ERROR: Content is not available".
    Does anybody know why this happened?

    Sorry, there were mistakes in jsp page and java files.
    I maked the channel "show exceptions" and found them out.

  • Need help with tomcat 5.5 and using java classes

    hey there,
    i am trying to set up tomcat 5.5 on my computer at home and have sucessfully done so. i have been trying to use Java classes inside my JSP files however tomcat thows an internal servlet error as follows:

    i have the classes located as the setup tutorial recommends (root/WEB-INF/classes/) and still nothing works. i would appreciate any help anyone can give.
    thanks,

    Which tutorial are you following?
    As of java1.4, all classes must be in packages for them to work in Tomcat. This means your beans and servlets too.
    Put your beans in a package, and then recompile them, and put them in the right place.
    eg
    package com.mypackage
    public class MyClass ...
    once compiled would go into WEB-INF/classes/com/mypackage/MyClass.class
    Are you using Product and ProductList classes in scriptlet code?
    Have you imported them with a page directive
    <%@ page import="com.mypackage.Product, com.mypackage.ProductList" %> ?

  • Java Classes and JSP`s (urgent)

    hi, my question is:
    How can i invoke normal java classes` methods using Jsp`s for this??, is it possible??, if it is, then how do you do this, and where do you have to put the java classes in order to find them from a jsp.
    thanks

    Hi,
    You can access normal java classes in JSP pages. You have to import them in the header like this:
    <%@ page language="java" import="//your java class file with package"%>
    or if u r using java beans, then use the <usebean> tag. Put the java classes in the classes directory. Which server u r using? If it is JWS, then u have a specified classes directory, where u have to put all the class files along with their packages. Hope this will help.

  • Can i Use java Class

    Can any help, can i use java class in
    froms 6 or any one have designed form
    of progress bar please help me

    Thanks for your reply...
    Actually the task is quite simple... It requires me to do a better interface for a tomcat server folders...
    For example, users are free to access
    http://apache.oss.eznetsols.org/jakarta/tomcat-5/v5.0.12-beta/
    to download the tomcat... However, its index may not nice and easy for browing.. Therefore, the task requires a new dynamic page to access this server folder, and get all file names under this folder, anlaysis whether it is file or directory..and finally get its path....
    It is quite easy to do a JSP page, but I don't know whether it is possible to do by using JavaScript .... Although JS is running in client side, the user/client also can access the tomcat folder, why not JavaScript?
    Thanks a lot!
