How to get context sensitive help in JSP Pages
Is it possible to display context sensitive help in JSP Pages when I press the tab key on the keyboard base on the key focus. I don�t want to use any applet or Swing components, because it�s a web page viewed on the browser
ThanksJava code inside a JSP is interpreted on the server and the HTML produced by the server it is shown in the client browser. The JSP code can incorporate calls to the JavaHelp API if it is available to the server. Those calls can be used on the server side to map parts of the JSP to contents of a help set (HTML pages).
Given that, you can provide context sensitive help, but when it comes to view help information, you either can show HTML only (without TOC, index, etc.) or you'd need an applet.

Need help w/ JSP formating a page.
Ok. I need to make the following code work. I think it needs help w/ formating is all. Below is the JSP page I would like it in as well as where I think the code should go. Not shure how to get it to display the output though.
var fullSessionName;
Function startHODSession(sessionName) {
var i = document.HODApplet.startSession(sessionName);
if (i == 0) {
fullSessionName = sessionName + document.HODApplet.getSessionID();
I need to run that part of code and display the output on a webpage. Any help would be awosme as I am lost w/ JSP more of a vb kind of guy. but learning quickly. Thanks for any help or advice.
Thanks
My JSP file:

</html>Great catch on the aplet and maybe that is where I am going wrong. So let me back up a little and maybe you can get me out of my bind.
Basically what I want for a test app is: a little text box w/ a button. type in an number and click the button.
the button will then send the info to a terminal emulator. (ibm host on demand)
So that is what the 3 include statements where for. I got that from the API example.
so what I really need the page to do is print the list of connections.
so I need to get the latest session ID:
var fullSessionName;
Function startHODSession(sessionName) {
var i = document.HODApplet.startSession(sessionName);
if (i == 0) {
fullSessionName = sessionName + document.HODApplet.getSessionID();
Then run:
public int sendKeys1 (String text)
The string being what was put in the box.
for right now i do not need error checking and i know the screen will be on the right spot to accpet the input.
so if there is a better way to make it work using an applet....Im all for it.
any ideas would be great.

Need serious help with JSP + JDBC/Database connection
Hey all,
I have to build an assignment using JSP pages. I am still pretty new and only learning through trial and error. I understand a bit now, and I have managed to get a bit done for it.
I am having the most trouble with a Login Screen. The requirements are that the a form in a webpage has Username/Number and Password, the user clicks Login, and thats about it. The values for the username/number and password NEED to come from the database and I cannot manage to do this. The thing I have done is basically hardcode the values into the SQL statement in the .jsp file. This works, but only for that one user.
I need it so it checks the username/number and password entered by the user, checks the database to see if they are in it, and if so, give access. I seriously am stuck and have no idea on what to do.
I dont even know if I have made these JSP pages correct for starters, I can send them out if someone is willing to look/help.
I have setup 3 other forms required for the assignment and they are reading data from the db and displaying within tables, I need to do this with non-hardcoded values aswell. Im pretty sure I need to use for example 'SELECT .... FROM .... WHERE username= +usrnm' (a variable instead of username="john" , this is hardcoded), I just CANNOT figure out how to go about it.
Its hard to explain through here so I hope I gave enough info. A friend of mine gave some psuedocode i should use to make it, it seems ok to follow, its just I do not know enough to do it. He suggested:
get the username and pass from the env vars
open the db
make an sql (eg SELECT user, pass FROM users WHERE user = envuser)
index.jsp points to login.jsp
login.jsp get the vars you put into index.jsp
opened the db
is the query returns nothing - then the user is wrong
OR if the passwords dont match
- redirect back to index.jsp
if it does match
- set up a session
- redirect to mainmenu.jsp
Anyway, thanks for any help you can give.
-AaronHi,
Try this... it may help you...
mainMenu.jsp
<html>
<body>
<form method="POST" action="login.jsp">
Username: <input type="text" name="cust_no">
<p>
Password: <input type="password" name="password">
<p>
<input type="submit" value="LOGIN">
</form>
</body>
</html>

try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

String query = "SELECT cust_no, password FROM customers WHERE cust_no='";
query += request.getParameter("cust_no") + "' AND password='";
query += request.getParameter("password") + "';";
ResultSet resSum = statement.executeQuery(query);
if (request.getParameter("cust_no").equalsIgnoreCase(resSum.getString("cust_no") && request.getParameter("password").equalsIgnoreCase(resSum.getString("password"))

I didn't check the code that I wrote. So you may have to fix some part of it. Also this may not be the best solution, but it will help you to understand the process easily.
The more efficient method is to check whether the result set returned from the database is null or not.... I hope you got the idea... Good luck!

JSP basic questions ( i think )
Hi, I'm new to JSP.
I established a database connection using JSP. However, I would prefer a java connection, so I have a program called JDBCBean.java which attempts the connection. However, when I compile this and place it in my classes folder, then try to use it in my jsp file, I get a "class not found" error. This confuses me, since it IS there and I set the classpath to the folder in which it is located....
The JDBC has : package oracle.jdbc at the top
and in my JSP file I have, for use bean, class = "oracle.jdbc.JDBCBean".
I can't figure out what causes my error, or how to fix it, so any help would be greatly appreciated.
Another thing I can' quite figure is the arguements stuff. Now I can pass parameters using a form...
For example, I tested with textbox "please enter a name". You enter a name, it then uses that parameter in the URL e.g. www.something.com/something.jsp?name=bob
But... what I want to do is have some sort of setup where, you have, say 3 types.
e.g. Type - 1 2 3
And if you click on 1, the parameter would be an SQL query. e.g. Select * from x where type = '1';
and then the page displays the results of my query.
Is this so hard? For the life of me, I can't find such info in my book and I've hunted the net and found nothing useful. All i find is about ASP, which I think is a good bit different.
Please help. Sample code or links or whatever would be great.
Thanks a lot.Ok, classpath is irrelevant? Understood.
This is the bean stuff i took from my book. I assume package and the class i have are correct.
Going by these, JDBCBean.class should be located in /oracle/jdbc/ yes??

</HTML>I haven't really modified the code yet, as I want to establish a working java connection first.
By the second part, what I meant was :
You have something like "select a type" and then you have the options - 1, 2 , 3.
If you choose 1, I want it to execute a query which will then display everything of type 1 on the page. e.g. pass the parameter (select * from table where type = '1';)
Basically, your page would then be "refreshed" displaying the data your query produces, using another bean I presume.

Help with jsp and servlets(litterature)
I'm planning on converting a asp website to jsp and I need to figure out the following:
1: servlet that gives out connection objects from a pool and manages "lost" connections to a mysql db
2: a bean that has getConnection and closeConnection that is used on every jsp page.
3: servlet/bean that can check size/dimesions/filetype on a remote url image
4: Figure out what users are logged in at every given moment. result: x users are on, these are user1, user2, user3. automatic removal when session runs out. probably need a servlet for this.
I got these books:
deitel java how to program 3rd edition
deitel advanced java 2 platform how to program
The last book has a servlet and jsp section ut I suspect that java has evolved since then so thats why I'm asking if you have any other suggestions that offer more than 2 chapters. Its really basic the stuff i have :)
Its been 3 years since I've touched java so i hope you guys can recomend jsp/servlet books that can answer these questions for me and help me get started with this project?
Thanks :)1. apache dbcp commons library.
http://jakarta.apache.org/commons/dbcp/
2. tomcat DataSource, which already has the dbpc logic incorporated into it.
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html
3. no idea, google may help
4. HttpSessionBindingListener. This allows you to monitor when a bean (such as a User bean) is added to the session and when it is removed from the session. This way you can track yourself which users are online.

Help with JSP/Weblogic/Tomcat Discrepencies
Hi,
I have something very strange happening. I recently did some JSP stuff on
WLS60SP1 and all went quite well. I then took those same JSP pages and tried
them out on the latest release of TOMCAT. I was really impressed that
everything seemed to be completely transparent and working just fine until
the following situation:
When I reference, within a JSP page, an object that has previously been
added to the request scope that has just been created, but not messed with
in anyway...meaning all the attributes in this bean have their default
values set...and they are all Strings with the exception of one Integer
using this format:
<%= custVal.getCustomerNumber() %>
- In WLS, what shows in the text field on the form is nothing, because
customer number in the custVal object is null (default for a String)..this
is what I want.
- In Tomcat, what shows it the word "null".
...here is the weird part, by changing from scriptlet references to the
<jsp:getProperty....> format such as....
<jsp:getProperty name="custVal" property="customerNumber"/>
-In WLS, he is still a happy camper and works just fine regardless of how I
reference the bean
-In Tomcat, I also get the correct results that I want.
So, unlike most postings, I found out how to fix it but I would like to know
why...any ideas?

I have a servlet which passes details to a jsp page, i am having trouble picking up what is passed in the jsp page can somebody help me with this?
this is the lines from the servlet which should pass the data:
request.setAttribute("notvalid", "whatShouldIputHere");
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/mypage.jsp");
dispatcher.forward(request, response); This is the jsp page i have tried to make:
<body>
<jsp:usebean id="notvalid"
class ="site.validator2"
Scope="request" />
<h1>message: </h1>
<jsp:getProperty name="notvalid" property="notvalid" />
</body>
</html>The fundamental problem is that the OP is asking questions about Servlet and JSP development without fully understanding the basics of containers and the rendezvous method of data sharing, life-cycle, data scope, and the like.
It is better that (s)he read up on the basics. -
I downloaded Lucene (apache product) and put the jar files in the /webapps/lucene/WEB-INF/lib directory. I created a simple jsp file:
test.jsp
<%@ page import = "org.apache.lucene.*" %>
<%@ page import = "java.io.*" %>
<%@ page import = "java.util.Date" %>
Test
<%
Date start = new Date();
IndexWriter writer = new IndexWriter("index", new StandardAnalyzer(), true);
%>
Started <%=start %>
When pulling it up I get:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred between lines: 7 and 12 in the jsp file: /test.jsp

I don't know what is wrong. The classpath I thought was set correctly to my jar files, but that doesn't seem to work. There isn't much documention on how to use JSP with Lucene. I got the basic examples they have working, but can't seem to get it working when I create my own stuff.
PLEASE HELP!!!!!!!!!!!!!!!!!Apparently I have to set the classpath EACH TIME.
How can I program this into the jsp so I don't have to do that? I thought that it would automatically find it if it was in the correct directory.
Also I am following the directions of lucene but it won't search correctly. Nothing gets returned in the example search. What gives??? -

hi
ive got a problem regarding jsp.... for starters i cant even view the jsp examples on the tomcat index page....
the servlet examples run fine and i can create my own servlets as well..
but when i try to create my own simple jsp page or run the examples i get the following error...
"......The server encountered an internal error () that prevented it from fulfilling this request.
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null....blah blah ..."
ive got a feeling this is a set up related error ... im running xp
with j2sdk1.4.2 and tomcat 4.1
any help would be appreciated as i have to get jsp up and running pretty soon .....
thanks
markHi cram81,
It sounds strange that jsp examples are not working from a default install. I can only guess that your classpath is setup wrong.
Another possibility is that the .jar files in CATALINA_HOME/common/lib are not the correct ones for compiling the jsp files.
Tomcat will always look in the above folder when attempting to compile jsp files.
Servlet examples work because they are precompiled, where-as the server always compiles jsp's at runtime if it's the first time that you are running that jsp or a change has been made to it.
Usually the jsp examples fail to compile because of a classpath error.
Check it out and let me know how you get on. -
Hi,
I am writing follow. java function inside my JSP
<jsp:useBean
id="inquiryBean" class = "com.bbh.actionworld.pagingcontrol.inquiry.Inquiry" scope = "session">
</jsp:useBean>
<%
int sIndex = inquiryBean.getStartIndex();
int eIndex = inquiryBean.getEndIndex();
int pSize = inquiryBean.getPageSize();
out.println("sIndex= " + sIndex + "eIndex = " + eIndex + "pSize = " + pSize);
%>
<%!
void getNextRecords() {
if (sIndex == 0)
if ((sIndex > 0) && (sIndex < dataArray.length))
sIndex = eIndex;
eIndex = sIndex + pSize;
out.println("after next sIndex = " + sIndex + "eIndex = " + eIndex + "pSize = " + pSize);
inquiryBean.setStartIndex(sIndex);
inquiryBean.setEndIndex(eIndex);
%>
I'm getting errors like sIndex, eIndex , pSize ,out , inquiryBean are undefined variables in function.
Can anybody help me ?
Thanx in advance.
-Priyado the three variables have local scope.
i.e have you declared them within a block and are trying
to use outside that block , if so they no longer exist in
memory.
just a guess. -
Any help with this will be really appreciated. I'm new to programming.
If I search for an ssn in a database, I want to view all records relating to that ssn. However, I am getting all the records in the table.
eg.
at the prompt for ssn, let's say I enter 111111111
I would like to see
111111111 abc xyz etc
111111111 pdg ppp etc
however, I am getting
000000000 utt tui etc
111111111 tug etg etc
How do I make limit the search to the ssn I want?
The related code is below.
Thanks.

Hi all
Does JSP support for each statement ??
Actually i need to cycle through each post variable like this in ASP
for each tempvarname in request.form
value1 = request.form(tempvarname)
pass=pass&value1
next
I am unable to do this JSP...
Can somebody help ?Use JSTL's c:forEach tag.
<c:forEach items="${param}" var="item">
${item.key} = ${item.value}<br/>
</c:forEach>That said, the need for this is a smell. Rethink your approach.
