Calling a java bean in a jsp file

hi all
i am working on a jsp project. my tomcat is installed on one machine and my java Bean on another. how do i call the javabean on my machine from the jsp file on tomcat. i'm using packages.
eg:
in the jsp file in tomcat, i'm using
<jsp:useBean id="student" scope="request" class="lab3.Student"/>
i get class not found error.
my main path for this Student Bean is say c://myLab/lab3 which has a lab3 folder with class files.
Thanks

eg:
in the jsp file in tomcat, i'm using
<jsp:useBean id="student" scope="request"
class="lab3.Student"/>
If you have a Context defined for c://mylab
then below that directory you should have a WEB-INF directory and then a classes directory and then within that your package structure...
so if the package is lab3 yo should have your Student class in:
c://mylab/WEB_INF/classes/lab3/Student.class
(asuming you have set up a Context that points at c://mylab...and your jsp file is there...)

Calling a java class in a JSP file

Hello,
I have a jsp file in which I call a java class.
I work with Tomcat 4.0.1
If I modify the java class and then I execute my JSP, it still be the old version of my class that is executed.
I don't understand why since if I creates a main function and I execute it, it works correctly!
Do you know what is the problem?
Thanks

i also have this problem.when i modify jsp file,it didn't execute inmediately. Then i restart tomcat,but problem also exist.
a few minute age,i execute jsp file again,it can appear the modified jsp.i don't down why
i work tomcat 5.0 windowxp

How to call the form bean value on jsp withthe help of jstl tag

hi
all friends
i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.
so how can i write above e.g in jstl

You use the jstl core:if or core:choose combined with the EL:
<c:if test="${empty users.userListForm}">
NO USERS FOUND
</c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.

Call to java bean but code not being executed.

Making a call to my javabean class called ch06_03.java from a jsp program shown below:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Using a java package.</title>
</head>
<body>
<% beans.ch06_03 messager = new beans.ch06_03(); %>
The message is: <%= messager.msg() %>

</html>
The call from jsp to javabean program is only returning the hello from java and NOT EXECUTING ANY OF THE CODE in the msg() method. I am checking my table landings_hold and nothing is there, my log file shows nothing. Why is the code not being executed except for the return statement?

Since you didn't use code-formatting tags ([ code ] and [ /code ] without the spaces) it's kinda hard to look at it. But I'm sure it DID execute much more than just the return statement - maybe you're not closing a file or db connection, or maybe you're seeing a cached page, so it actually isn't executing ANYTHING on the server (is your browser set to never check for newer pages so it (almost) always returns from cache, for example?)

Invoking a method from a java class to a jsp file

Maybe i'm going through a very basic error, but as i've looked for in some forums and nothing found decided to post. So let's go to the problem.
Well, i have a form in a jsp file, it's basicaly html, but as i need some select boxes populated with data from the database i decided to create some methods in java classes. This is the point.
My method receive some attributes, like the table and colums names, the name of the select box and the HttpServletResponse object.
So after making all the database process. The method is supposed to write the result through the out.println(); object
It goes everything all right except that the method seems to be called first than the html code coz' my select boxes comes above the head in the begin of the page and was supposed to come in the middle.
part of the code:
package pacote;
import java.packages.*
public class Class{
public void metodo(HttpServletResponse response, String tableName, String column name, String selectName){
PrintWriter out = response.getWriter();
openConnection();
//After making the query stuff
//caso n�o haja nada na consulta
     if(rst == null)
     out.println("N�o h� registros.");
     else{
     out.println( "<select name='" +SelectName + "' id='" +SelectName + "' class=\"input_ob\" >");
     out.println( "<option value=''>Escolha: "+objeto+"</option>");
     //fill the select body with options; A while that sweap the resultSet and use the out object to write the results
     getSelectBody(out,rst, selectValue);
}This method is called this way:
<tr valign="baseline">
    <td nowrap align="right">Grupo</td>
    <jsp:useBean id="m" scope="page" class="pacote.Class" />
        <td>
          <%
          try{
               m.metodo(response, "tabela","grupo","id_grupo);
          } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
                    %></td>I'd like to know what i'm missing here. why the answer doesn't go in the place It's supposed to go.
any answer will be greatly apreciated

The issue is caused because you are using the response to get the writer directly.
The JSP has gotten the same writer, but has wrapped it in a JSPWriter class. That class has got a buffer.
So it writes the beginning html to the JSPWriter buffer.
You write your stuff to the response writer - gets sent to the output.
It writes more stuff to the JSPWriter buffer, then flushes that buffer - at which point all the text written into the JSP writer now gets added to the response.
You see how your code is coming out first?
Solution - instead of getting the writer from the response, pass the writer into your method (maybe instead of response if you don't use response for anything else)
public void metodo(Writer jspWriter, String tableName, String column name, String selectName){
PrintWriter out = new PrintWriter(jspWriter);
...That means that you will be writing to the same writer, and the text should come out in sequence.

Tomcat 6 Calling a Java Servlet from a JSP Page

Ok, jsp pages to not contain java beans, java beans are separate classes which you access from a jsp.
Is this what you have done, i.e. created classes under classes/yourPackage ?
If so, you do not need to recompile the class when you move it, you can move the pre-compiled class file.
In terms of your error, I have no idea, but it looks interesting!!
The most likely cause is a difference in the JDK versions you are running on the different machines. If the JDK on windows 2000 is older, you may need to upgrade it.

Render Tree Table, got java.beans.IntrospectionException in Log file.

Hi,
I have a tree table defined in a jspx page. I got the following exception in the Log file when the UI try to render the tree table in the first time. This won't affect anything in the UI itself. It will render the tree table in the UI without problem. And this exception is only shown up in the Log for one time. However, I'd like to know why is that? How can I prevent such exception in the Log?
I tried to add the try catch in the constructor of the backing bean for this page. But the exception is not from there.
Please help!

JSP-can i reuse the instance of a bean in another .jsp file

am having a bean like clsStudent and i have used the usebean tag and setproperty to set all the values of the same bean. then i want to access the contents in the instane of clsStudent in another .JSP file.

That doesn't sound like you're doing it right. Beans, like any java class, are actually defined in Java, and class files placed in the WEB-INF directory (By the way class names should be capitalised).
JSPs shouldn't be populating beans, they should be generating HTML based on them. If you're loading form data into a bean use a servlet.
That said there's no problem referencing beans in multiple JSPs, but you have to pay attention to how the actual reference gets into the JSP. This is done through "scope" on useBean. Generally a Servlet builds a bean and places it into the request attributes, then forwards to a JSP to format the HTML.

How to call a java class in a bat file

I need to call a Test.java class in a bat files .It refer .DOM.jar
in C:/url; How do i call the java class i need the syntax
Thanks lot

assuming %JAVA_HOME% is defined (else substitue it with your java installation directory)
here is the content of launch.bat:
cd C:/url (or cd c:\url ) (or cd c: followed by cd url)
%JAVA_HOME%\bin java -classpath .;DOM.jar Test

Unable to import a java class in a jsp file

Hi,
I am trying to import a java class in my jsp.
------------------jsp---------------
<jsp:useBean id="form" class="com.company.portlets.searchApps.object.SearchOBJ" scope="request" />
<jsp:setProperty name="form" property="*" />
<input type="TEXT" name="projectID" value='<%= form.getProjectID() %>'>
When I run the above JSP, it says that class 'com.company.portlets.searchApps.object.SearchOBJ' cannot be found.
Why?
My project structure looks like this:
Project
+Application Sources
++com.company.portlets.searchApps.object
+++SearchOBJ.java
+Web Content
++htdocs
+++searchappsportlet
++++SearchAppsPortletShowPage.jsp
++WEB-INF
+++index.jsp
+Resources
++SearchApps.deploy
Please advice...thanks!

The way that JDeveloper organized the files was like this:
C:\jdev1012\jdev\mywork\WksSearchApps\Project\classes\com\company\portlets\searchAPPS\object\SearchOBJ.class
I am assuming that JDeveloper puts the file where they are suppose to be...if not, how do I change that?
thanks,
hussain

How to pass a populated Java bean to a jsp

Hi,
I'm new to J2EE world. I want to know how should I pass a populated Java Bean (not EJB) to a JSP without displaying that JSP in the next step. I would be much grateful to anyone who gives a solution to my problem.
Thanks in advance
With best regards
Sampath

Urk?
A JSP is meant to be displayed. If there's business logic in that JSP, get it out of there. Process the bean as needed on the server side and send the flow on to some view that actually should be displayed.

How to call a function defined in a JSP file into a servlet?

Hi
I have defined a JSP file with some functions in it. I am including this JSP file into other JSP files so that these functions can be used. Now is there soe way, that I can include this file in a servlet as well and use the defined functions in the servlet as well.
Thanks and Regards
Vikram

I assume you have a function with OUT arguments because you need to return at least two distinct things from this function? The functions return value and this OUT argument, too. Right? For the sake of argument, let's say that you're trying to return a VARCHAR2 value and a NUMBER value from this function.
Assuming that you cannot just wrap your existing function with a function that does not have OUT arguments, the first idea that pops to mind is to create an Oracle8 type that looks like:
CREATE TYPE MYREC AS OBJECT (V VARCHAR2(80), N NUMBER);Then you could rewrite your function to return an instance of this MYREC type instead of having one return value and one OUT parameter.
Then create a BC4J domain for this Oracle8 type (which will mimic its nested structure), and then you can just select the value straight-away in your view object.
I just tried this idea with 9.0.2 production and it works.
The Domain you create will have getV() and getN() accessors on it so you can get at the nested values in the MyRec domain "record" structure.
The other way would involve building a programmatic view object that sources the data for your VO programmatically. If I think of anything else I'll post something here.
