RE: jsp:useBean error
Hello again, Filip, I tried to "package up" the 2 required files, login.jsp and LDAPAuth.java into a newly created "org.burrus.test" folder, and then compiled them into that same folder/directory to create 2 .class files, but then when I tried to run the whole program in my JBuilder 8, I STILL got, for my efforts, the old 505 server error page: Apache Tomcat/4.0.6 - HTTP Status 500 - Internal Server Errortype Exception reportmessage Internal Server Errordescription The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.exception org.apache.jasper.JasperException: Unable to compile class for JSPNote: sun.tools.javac.Main has been deprecated.

RE: jsp:useBean error
SCNR (just for my humor): http://java.sun.com/docs/books/tutorial/getStarted/cupojava/index.html org.burrus.[name of file] means that you have a directory structure like: org +-burrus in that subdirectory you have your class files [name of file] So in case you have a class named "MyFirstCupOfJava" that you save under: [wherever your workspace is]/org/burrus/MyFirstCupOfJava.java you could import this file with: "import org.burrus.MyFirstCupOfJava" in any of your other projects java files.

RE: jsp:useBean error
okey dokey,
here we go
http://java.sun.com/docs/books/tutorial/java/interpack/packages.html
example: (look at the package statement)
//--source of java file---
package com.filip.test;
public class Data implements java.io.Serializable
{
private String data;
public Data(String data) { this.data = data;}
public String toString() { return data; }
}
//--end of java file--
This file now exists in a "package" called com.filip.test;
when you compile this file you can do this:
"javac -d . Data.java"
this will compile the file Data.java into Data.class and place this file in a folder
in the following way
./com/filip/test/Data.class
This file, should now be placed under /yourwebapp/WEB-INF/classes/com/filip/test/
Using JBuilder, when you say "New Class" it asks you to specify a package.
When referencing this class from other classes you can use the "import" statement.
This is the short version, so let me know if you have any direct questions.
Packages are not specific to Tomcat, it is a part of the Java language.
Filip

RE: jsp:useBean error
Nope, there is nothing special you have to do in JBuilder, it should take care of everything for you. But you do have to put your classfiles in a package, and then it will work. ie, your .java files should have a "package" statement in the top of it.

[snip] Please try to respond to me with some useful advice about how I can successfully execute this JSP, because it doesn't look too much like anyone else in this newsgroup much feels like doing so, sad to say! [snip] With manners like that, it's really no wonder... Anyway, Steve, it's a ClassNotFoundError. You didn't put your class in a package. Put it in a package (example: com.burrus.authentication) and then make sure that the compiled class file is in the WEB-INF/classes/com/burrus/authentication (following the example) directory. Quite a jump from having trouble getting the examples to work to LDAP authentication!! Perhaps backing the truck up a bit and reinforcing the fundamentals would be wise. Just a thought... HTH, -Jeff
RE: jsp:useBean error
ok, If the LDAPAuthBean is your class, try to add a package to it. I think Tomcat 4.x does funky stuff with classes without packages, and here is looks like it is prepending org.apache.jsp to the prefix. if you want, send me your war file.

In a forward.jsp, I have:
<%@ page import="Mylogin.UserLoginBean" %>
My class Mylogin is defined in WEB-INF/classes/Mylogin/UserLoginBean. It
is suppose to validate a use login:
package Mylogin;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
public class UserLoginBean{
private String firstName;
private String lastName;
public UserLoginBean(){
}
public String getFirstName(){
return this.firstName;
}
public String getLastName(){
return this.lastName;
}
public void setFirstName(String firstName){
this.firstName=firstName;
}
public void setLastName(String lastName){
this.lastName=lastName;
}
public boolean isRegistered(){
try {
Context ctx = (Context)new
InitialContext().lookup("java:comp/env");
DataSource ds =
(DataSource)ctx.lookup("jdbcdb");
Connection conn = ds.getConnection();
if (conn != null)
System.out.println("CONNETED");
String stm="Select first_name from names where
item_id=?";
PreparedStatement selectStatement =
conn.prepareStatement(stm);
selectStatement.setString(1,firstName);
ResultSet rs = selectStatement.executeQuery();
if (rs.next())
{
setFirstName(rs.getString("first_name"));
conn.close();
return true;
}
else
{
conn.close();
return false;
}
} catch (Exception e) {
System.out.println("Got an exception! ");
System.out.println(e.getMessage());
return false;
}
}
}
Thanks for all the help in advance.
