Newbie in JSP...help

pls post some codes in jsp in adding,editing,deleting and viewing data in the database..i am using tomcat,apache,mysql...thanx

Asking for code is not going to work here. Rather elaborate your coding problem in detail. Where exactly are you stucking while writing code?
It is fairly straightforward. Write a DAO class with create/read/update/delete methods which interacts with the database. Write a Servlet which handles the request parameters and interacts with the DAO class. Write a JSP file with HTML tables and forms which sends the request parameters to the Servlet.

Total newbie for jsp..plz help

frendz...me a total newbie to jsp.havin some problem in it.i have already installed jdk,jwsdp2.0 wif its tomcat container.Already set the path for both ..such as JAVA_HOME=E:\Program Files\Java\jdk1.5.0_06
TOMCAT_HOME=E:\tomcat50-jwsdp
and could execute the sample jsp's perfectly.But having problem wif my jsp tutorials. such as when i wrote this counter codes in notepad..
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<html>
<head>
<tittle>Jsp Declaration</tittle>
</head>
<body>
<h1>Declarations</h1>
<%! int j=0;%>
<h2>Counter</h2>
<p>This page has been hit <span> <% ++j %> </span> times since it was first loaded.</p>
</body>
</html>
and i paste it in webapps in tomcat folder.
What should i do to view the jsp file?isaved as counter.jsp.if i right click and view it in IE/firefox it only shows the source code.is there any mistake in the codes?or i did i do anything wrong?how shall i compile these files?help me aout wif my basics please.thanks bro's..

"I pasted it in webapps in tomcat folder".
Webapplications need to go in their own subdirectory inside the webapps directory. Say you want a webapp 'test', then you would store your JSP as
TOMCAT_DIR\webapps\test\counter.jsp
Now you can open this JSP in your browser. Assuming Tomcat is running on the localhost and the default port 8080, the url would be:
http://localhost:8080/test/counter.jsp
If that doesn't work something is horribly misconfigured.

Newbie to JSP needs help

I'm running tomcat and apache and basic servlets work fine, however when I try the usebean tag; I get an error message "CLASS not found". The class object is in the same directory as the servlet?
Any suggestions?

Newbie to JSP/Struts: Where to get started

I would like to begin experimenting with JSP and the struts framework. I'm a java newbie but a relatively quick learner.
First, what products do I need to use struts/JSP ?
I have 9iAS standard edition release 1.0.2.1 and an oracle database std edition without the JVM installed. Do I need the JVM in the database ? Can JSP use a JVM outside the database ? Do I need enterprise edition ?
Do I need Jdevelopper 9i or can I learn to use JSP with simple tools (HTML editor) first ?
Does struts need JSP 2.0 spec or the JSP 1.1 that comes with iAS 1.0.2.1 is OK ? Is JSP 2.0 = JSP 1.2 (Like J2EE = JDK1.2 and up) There is a lot of version/naming confusion going on in java, you got any site that can help me untangle this mess ?
Thanks a lot
You can reply to [email protected]

Thanks for your response.
We actually use oracle 8.1.7 and 9iAS (PL/SQL gateway and http server). We would like to jump on the Java Bandwagon before we are left in the dust. We first need to be able to understand a lot of technology/concepts/buzzwords.
We started basic Java programming (Applications) but would prefer to get an idea of "The big picture".
By that, I mean, we need to be able to understand/design/architect sound applications and be able to talk to the community and understand what they are saying. Right now, reading the media or forums is just a big bunch of buzzwords that are ever changing and we cannot get a grasp on it.
We not only need to get aquainted with the concepts, but we also need to be able to determine wether product xyz fits in the architecture, etc...
If you were to get a couple of good books to answer some questions, where would you begin ?
Kind of questions we might have are:
- What is the difference between Jserv and Tomcat ?
- What excatly is tomcat ? A replacement for Jserv ?
- Can Jserv be used as a container for struts apps or do you need tomcat ? If you need tomcat, does it come with some version of 9ias ?
- What is a java web service ?
- I read a lot about Enterprise Java Beans etc.. What are they, what are there purpose ? It seems like it is a standard, what are they used for ? If it is a standard, does this mean that If I buy a set of EJB from a vendor, it would offer the same beans as another vendor ? Is Oracle BC4J an implementation of EJB with added functionality ? Is it proprietary ?
- Buzzwords everywhere: MVC, EJB, J2EE, BC4J etc.. What are the definitions.
- Is oracle's java vision proprietary or are they really following the rest of the world ? For example, is BC4J compatible with EJB ?
- What is a Framework
- What exactly is JSP.
- Can STRUTS be used to access an oracle database ? If so, what are the required components (I guess you need JDBC or SQLJ) but does the oracle database need to be java enabled ?
- Even if you use oracle 9ias as an application server, can you use non-proprietary development methods/architectures/techniques that could be easily implemented somewhere else using another vendor's application server (Ex: Apache + Tomcat, WebSphere, etc...)
- Struts seems to be an interesting thing. I see that it was developped to encourage code reuse and prevent everyone from reinventing the wheel. But I cannot understand what exactly a developper had to write before struts was there. I mean, there must be alternatives to strut, if so what is the purpose of the framework ?
A lot of questions, but we need to understand the basics before we jump on the java bandwagon. If we wait, we'll be left in the dust and we need to keep current.
Thanks in advance.

Unable to compile class for JSP--- help me plz!!!!!

hi friends;
Pease suggest me where i am wrong, i think javabean is not instantiated in jsp file.may be it is related to the classpath of javabean. i have not set any variable for javabean classpath. and i put javabean class file in

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.

Java mail and jsp -HELP!! HELP!!

Hi all
I have a simple email module with a jsp page and a html page I am trying to connect to a yahoo smtp server and send a mail from the webpage to the smtp server - I am getting an Authentication required error.
error ##
org.apache.jasper.JasperException: Sending failed;
nested exception is:
     class javax.mail.MessagingException: 530 authentication required - for help go to http://help.yahoo.com/help/us/sbc/dsl/mail/pop/pop-11.html
Can anyonne tell me how to use a simple smtp email facility
how to use an authenticator in the jsp
ciao
laodingdockjavaguy

It's required that you authentificate yourself at the smpt server
The following snipplet sends a msg using the smtp protocol.
Transport tr = session.getTransport("smtp");
tr.connect(smtphost, username, password);
msg.saveChanges();     // don't forget this
tr.sendMessage(msg, msg.getAllRecipients());
tr.close();If this still fails You can also try to set the property mail.smtp.auth to true.
mail.smtp.auth      boolean      If true, attempt to authenticate the user using the AUTH command. Defaults to false.see also http://java.sun.com/products/javamail/1.3/docs/javadocs/com/sun/mail/smtp/package-summary.html
for a complete description of the properties supported by the smpt transport.
hope it helps

J2ee security newbie: integrated authentication help

I am trying to build a set of JSPs/servlets that require authentication and probably authorization. The jsp / sevlets should be able to authenticate against any underlying password system, or should cope with most common systems such as win2k / unix etc. I do not want to force the organisation to build a new database of users / passwords or to type in passwords in clear text in xml files.
I would preferably like to use form-based authentication to avoid Http basic clear text password sending. This will also allow me to custmize the UI of the login screen.
The solution should not be container specific. or at least the containers (tomcat + webspehere) should allow for it in their own way.
After a lot of reseasrch on the web, I cant seem to find an accepted way of doing this. I would like comments on the choices I have made so far and the choices I should be making. Any links to reading material would be helpful. I would like to understand which lower level technologies to depend upon eg LDAP / Kerberos etc. Any help will be appreciated
TIA,
Zdz

Most container come with the ability to put security constraints in the web.xml file.
Then, you can set up your container to do the authentication (tomcat call this Realm). And there is a JAAS realm that can be configured a little bit like PAM in Unix/Linux.
There is also a Security Filter around on the net.
Hope this helps.

Newbie to JSP

Hi ,
I ran into a problem running JSPs. I am working with Tomcat 6.0 and JDK 1.5. I ran a very simple jsp file and it worked. Then I configured and got servlets working and now JSPs are no longer working.

There are multiple class loaders involved here and each of them uses its own classpath. The environment classpath will be used by java.exe that starts up your Tomcat unless it is overriden by -classpath parameter. The class loader that loads your web application a standard set of directories in its class path too - all jar files under WEB-INF/lib, all classes under WEB-INF/classes.
Generally, it's a good idea to add a jar file to the class path of the most relevant class loader (web app class loader in this case). That makes your application self-contained and totally transparent to environment changes outside the web app. So put this jar under WEB-INF/lib and make it work. Once you get more comfortable with Java technology, you can read more about class loaders, delegation used by class loaders and class loading hierarchy. You will then be able to appreciate why the approach mentioned by us is the best way to do things. Hope this helps!

Newbie question: JSP x JSTL (Will JSTL kill JSP?)

Hi,
I'm newbie in java development and know I'm learning about jsp and jstl.
I'm reading some articles about jstl, but my doubt remains...
Was jstl create to kill jsp in apresentation layer?
Please, if possible, show me an example that I really need use jsp instead of jstl?
What kind of things can't I do with jstl?
Thanks a lot

I'm sorry, my question wasn't very clear.
When I said JSP, I wanted say Scriptlet...
My central point is that Scriptlet is very confortable for me at the moment...
So, I don't see a motive to change:
<% if (1 == 2) }....
to
<c:if test="1 eq 2">...Lots of motive to change.
Now... you can say that jstl is more easy, Or you can say that JSTL is easier.
but if a big number of people start to use it, it will increase and will turn another programming language...It sounds like you think this is a new thing. JSTL has been around for a very long time. 2001 vintage. It's already here, dude.
Besides, it's not a programming language per se. There will be other tag libraries, but those are custom. JSTL as written hasn't changed in years. The standard won't expand.
So, why create another programming language if we have Scriptlet to do the same?Like I said before, scriptlets were the mistake. They're unreadable, ugly, and encourage putting logic in JSPs. Very bad, indeed.

Newbie with JSP & JDBC questions

Hi. I have a quick question. I have a client jsp page with a table, listing all the fields from my mySQL table called kellybclients. At the end of each row, I also have a submit button that I would like navigate the user to the campus jsp page that only shows the data associated with the client who's button they clicked on in the table. I'm trying to figure out how to pass this data from my JSP into the rowset.setCommand method in my connection/data bean. I am using a cached row set. Here's the code from my bean:
* To change this template, choose Tools | Templates
* and open the template in the editor.
package ETS;
import java.sql.SQLException;
import javax.sql.rowset.CachedRowSet;
import java.util.ArrayList;
import com.sun.rowset.CachedRowSetImpl;
public class CampusDataBean {
    private CachedRowSet rowSet;
public CampusDataBean() throws Exception
    Class.forName("com.mysql.jdbc.Driver");
    rowSet = new CachedRowSetImpl();
    rowSet.setUrl("jdbc:mysql://traderseven.nmsu.edu/is470Spring08?relaxAutoCommit=true");
    rowSet.setUsername("is470Spring08");
    rowSet.setPassword("1DoNtier");
    rowSet.setCommand("SELECT campid, clientid, campname,campcounty FROM kellybCampus WHERE clientid=?");
    CampusBean camp = new CampusBean();
    rowSet.setString(1, camp.getClientID());
    rowSet.execute();
public ArrayList<CampusBean> getCampusList() throws SQLException
    ArrayList<CampusBean> campusList = new ArrayList<CampusBean>();
    rowSet.beforeFirst();
    while(rowSet.next())
      CampusBean campus = new CampusBean();
      campus.setCampID(rowSet.getString(1));
      campus.setClientID(rowSet.getString (2));
      campus.setCampName(rowSet.getString(3));
      campus.setCounty(rowSet.getString(4));
      campusList.add(campus);
    return campusList;
public void addCampus(CampusBean campus) throws SQLException
    rowSet.moveToInsertRow();
    rowSet.updateString(1,campus.getCampID());
    rowSet.updateString(2,campus.getClientID());
    rowSet.updateString(3,campus.getCampName());
    rowSet.updateString(4,campus.getCounty());
    rowSet.insertRow();
    rowSet.moveToCurrentRow();
    rowSet.acceptChanges();
}I'm sorry if this is too vague. I'd appreciate any help, fixes, or pointers on where to learn how to do this. Thank you again.

So the button should be a Submit button for a form. There are a couple of different methods for doing this:
1) Each row on the table can be a different form, each form uses the same action (servlet) target and has a hidden input with a unique identifier for each of the clients:
<table>
<tr><form action="selectClient" method="post"><td> etc </td><td><input type="hidden" name="id" value="1"/><input type="submit"/></td></form></tr>
<tr><form action="selectClient" method="post"><td> etc </td><td><input type="hidden" name="id" value="2"/><input type="submit"/></td></form></tr>2) Use a single form with a button type=submit for each row with different values (Note: This is broken in IE7 so you probably shouldn't use it)
<table><form action="selectClient" method="post">
<tr><td> etc </td><td><button type="submit" name="id" value="1">Submit</button></td></tr>
<tr><td> etc </td><td><button type="submit" name="id" value="2">Submit</button></td></tr>3) Use a single form, have a hidden value with a blank value. Each row has a submit button with a javascript onclick method that sets the form's hidden value to one appropriate to the row, then submits the form. I won't show you this code but there are examples on the web.
4) Use a single form with an input="submit" element on each row. Each button would have a different name with the ID info encoded in it, then you would have server-side code that takes parameters, finds the right one and parses out the proper row to edit:
<table><form action="selectClient" method="post">
<tr><td> etc </td><td><input type="submit" name="submit__id_1"/></td></tr>
<tr><td> etc </td><td><input type="submit" name="submit__id_2"/></td></tr>I think most people end up doing some variant of 3, which I don't like because I hate to rely on JavaScript to make my web apps work properly. I would prefer 4, which takes more work on the server side (which I like better) but 1 works just as well with a lot more typing and uglier HTML code. Actually, I would like 2 the best because that is pretty much what the <button> element was designed for, but Microsoft screwed that up.

Any direction as to what has gone wrong is greatly appreciated! Thank you!

Hi,
do you use docid or iDocID in your URL. Please note that the parameter names are case-sensitive.
I would recommend to take a look at the documentation in order to identify the correct syntax for your URL
