What directory to put bean classes on application server PE9
Hello Everyone,
I am new to Java EE and I am in need of a little assistance. I am in the middle of a JSP tutorial and it is teaching how to apply the <jsp:useBean> tag however I am unsure of where to put my complied bean classes on the server so that it can find them. Is there a special folder that is on the server's class path in which to place these? if not what is the default classpath of the server and how do I change it to include the folder that I have my bean classes in?
Much Thanks in advance,
Robert

Here is the stack trace from the server that is produced when the form from the tutorial tries to find my bean.
org.apache.jasper.JasperException: Unable to compile class for JSP

[javac] 3 errors
and here is the code
First here is the form that requests the wordpro.jsp
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Bean Input</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<form action="wordpro.jsp" method="post">
Enter Word:
<input type="text" name="word">
<select name="mode">
<option value="1" selected> Reverse</option>
<option value="2">Spellcheck</option>
</select>
<input type="submit" name="Go" value="Submit">
</form>
</body>
</html>
The here is the wordpro.jsp which in return trys to use the SpellCheck bean.
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<jsp:useBean id="help" scope="request" class="SpellCheck" />
<jsp:setProperty name="help" property="*"/>
<html>
<head>
<title>WordPro</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
You entered the input, <b> <%= request.getParameter("word") %></b>
The process output is:
<%= Integer.parseInt(request.getParameter("mode")) == 1 ? help.reverse() : ""+help.check() %>
</body>
</html>
Then finally here is the bean itself
public class SpellCheck{
private String word;
public SpellCheck(){
}
public String reverse(){
return (new StringBuffer(word).reverse()).toString();
}
public boolean check(){
return true;
}
public String getWord(){
return word;
}
public void setWord(String aWord){
word = aWord;
}
}
I currently have the bean in the docroot folder on the server but I know this is not right. Where do I put the bean so that it can be seen on the class path? Also once I have done this how do I point the useBean tag to the folder that the bean is in because I know that just putting the class name like this won't work. <jsp:useBean id="help" scope="request" class="SpellCheck"/>. It seems to be looking for my bean class in the wordpro.jsp right now at least that is what I get from the stack trace.
Again thanks in advance,
Robert
P.S. I tried creating my own folder and putting it on the path which is what one article I read suggested, but that didn't seem to work. I guess until someone can help me by answering my question I will use a simpler application server. I found one called Blazix at www.blazix.com/download.html that tells in the documentation that the classes folder is the default folder for beans.
