Re: Any advantages of taglibs
Hi I just wrote a brief article about this. http://www.jspinsider.com/articles/jsp/intrototags.html A quick hash of some of the pros / cons The problem with tags are: -An initial extra up front cost in building the tags. -An additional overhead in processing the tag. -Adding some complexity to certain operation where scriptlets would be easier. The benefits that tags have: -Reusability -Easier to maintain pages and have other people use same page. -Easier to expand and change functionality without changing existing pages -Expand JSP -There are some things you can do in tags YOU CANT achieve with scriptlets -Better than templates for maintainability -Easier to move code from project to project, vs scriptlets which dont move as well. This is a very quick list and the benefit list goes on and on, but its 1 am I need some sleep, check the article for more details...

Luckily, though, there are many cases where the worst case > simply doesn't happen. Yes I've hit the worst case. It doesn't mean I can't get my job done, its just that its *so* much slower than it should be. And there is no workaround, the Java code that is generated by the JSP is so much slower than it should be. Unfortunately there is no way around it (AFAIK) until the JSP spec is improved to add more complex flow control to JSP pages. Right now today JSP tags flow control are just way too simplistic. If you want to do something as complex as a switch statement efficiently, you shouldn't use JSP custom tags, you should use Java code. This is a big shame IMHO > For example, you mention object creation for the tags; if the same tag is > used over and over again in a given page, many JSP containers will simply > reuse previous instances. I kinda assumed that one too.

Sure. Though creating many unnecessary objects and calling many unnecessary functions per request is a waste of computing resources no matter how clever HotSpot is getting. > You can, in fact, include methods in JSP snippets, Yes you can declare regular all-Java methods - you can't use regular JSP in the funciton body.

Not if done inside a large loop. Creating and manipulating (say) 10,000 objects per request unnecessarily when *there is no need to do this whatsoever* is a waste of memory and CPU on a heavily loaded web server.

Sorting line items in a ShoppingCart
Hi... For example, if I have a ShoppingCart object which contains an ArrayList of lineItem objects. Each lineitem object contains the attribute productName, productPrice, productCode, and quantity. Here's the expected behavior. For example... initially it's sorted by productCode, productName, productPrice, and quantity. If the user clicks productName then it will be sorted by productName, productCode, productPrice, and quantity. If the user clicks productPrice then it will be sorted by productPrice, productName, productCode, and quantity. and so on... Initially I planned to use Comparator but this can only be used for sorting a single column. How do I implement such functionality? thank you very much your help will be very much appreciated.

Re: Sorting line items in a ShoppingCart
Hi ,
U can sort using comparator by having a flag to distinguish what to sort on
for eg if u want to sort on product quantity
class Test implements comparable
{
boolean flgSortOnProductPrice=false;
.
.
.
public Test()
{
}
public setFlgSortOnProductPrice( boolean sort)
{
this.flgSortOnProductPrice=true;
//set all flags to false
}
public int compareTo(Object obj1,Object obj2)
{
lineitem l1=(lineitem) obj1;
lineitem l2=(lineitem) obj2;
i f(flgSortOnProductPrice)
{
return (l1.getProducttPrice()).compareTo(l2.getProductPrice())
}
else
.
.
.
.
}
}
now oto use this
Arraylist al1;
test =new Test();
/say sort on product price
test.setFlgSortOnProductPrice(true);
Collections.sort(al1,test);
to sort on proctcode
test.setFlag(true);
Collections.sort(al1,test);
Maybe this helps

Problems with PreparedStatements and LIKE
Hello. I´m trying to execute an PreparedStatement that contains a SQL instruction like this: "SELECT COUNT(*) FROM USERS WHERE NAME LIKE ? " I'm putting as parameter a String, for example "David". In the data-base there is a record which NAME field contains "David", but when I execute the PreparedStament it recovers 0 otherwise if I use an normal Statement that contains "SELECT COUNT(*) FROM USERS WHERE NAME LIKE 'David' " or if I use '=' in place of 'LIKE', it runs OK.

Re: Sorting line items in a ShoppingCart
Comparators allow you to sort based on however many columns you want. See the docs for Comparator, from http://java.sun.com/j2se/1.3/docs/api/index.html for more information.

Hi
how do you implement a carriage return when using JSP to construct the body
of an email?
For example, I want the email to look like this:

Instead when the form submitting this data is processed and the email
constructed I get this:
Make: FordModel: MustangMovie: Bullet
Any help appreciated.

Re: Diff bet asp & jsp
Nice reply. . .thanks for the background and bio. -Don Makoviney -Original Message- From: JSP Insider [mailto:[EMAIL PROTECTED]] Sent: Saturday, February 10, 2001 1:42 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Diff bet asp & jsp Good Morning Don, I suppose I should answer this email since you asked me a pretty direct question on my beliefs. Hmm Am I Biased? Let's see and examine this in more detail: I have been programming ASP since it was first released over 3-4 years ago. In fact I still programming in ASP today. I like ASP a lot. In fact ask any of my co workers and they will say I am a fan and supporter of ASP. I have successfully implemented many ASP sites. I still have recommended and am in process of helping start up several new ASP projects. Hmm. Ok. So far so good. Now let's look at JSP I started programming Java at the same time as ASP. And I have been programming JSP for the past year. Again I like JSP alot and again ask any of my co workers and they will say I am a fan and supporter of JSP. Again I have sucessfully implemented JSP sites. Again I am in the middle of setting up JSP projects. In fact I liked JSP enough to start up the JSPInsider web site. Hmm Ok still So far so good all things seem pretty equal. So now I am forced to compare the two platforms BASED ON real expereinces of using each. And I personally find JSP to be a better server side solution most of the time. I am not saying ASP is a bad solution It is great solution. Read what I have written and you will find I am an ASP supporter. But in programming both ASP and JSP I have found from practical experience that JSP is currently the stronger solution. Program JSP for 6 months and then make your own decisions. Don't believe what I say or what others write. In the end it is something you have to decide for yourself. THE TRUTH: JSP isn't for everyone and ASP isn't for everyone. THE SOLUTION Use the solution that is right for you. I just believe and my experience as it now stands JSP is the stronger of the two systems. In a year ASP+ might be the stronger. But you must understand my judgements are based upon hard and true and tried experiences. Killer specs means nothing to me, they are just specs. I have to produce a product and I will use the one right for my customer. So yes I suppose I am biased slighly in favor to JSP due to my successful experiences, But isnt everyone biased?? Obviously you are heavily biased towards ASP+ as I can tell from the strength of your feelings in the email! Is this bad? No of course not, expecially if it gets the job done. If you are living or breathing of course you will have your favorite tool to use, based on the tools you are successful with. The real question is are you open minded and can you be flexible to use the right tool for the right Job! KEEPING AN OPEN MIND And in that I always have an open mind, that is why I build both ASP and JSP web applications, because neither one is right for everyone. However, my experiences and my currently perffered solution is JSP as it offers the most maintainable and easiest to build reusable web solutions. NO amont of BETA specs will change my mind in this since it doesn't count until production, and this isn't a matter of being open minded but realistic. Anyone who builds a house of cards on beta software deserves the house they build, sometimes the gamble wins but more often the gamble loses. I hope your programming path in ASP+ is as smooth as you state it will be. ASP+ is a complete rewrite of the ASP rules and in this I reserve the right to have my have doubts until it has in production for 6 months. Once it has been in production for six months get back in contact with me and ask me how I feel then and please share your experiences for I will be interesting in comparing notes. However, after looking at ASP+ and still working with ASP 3.0 I have decided its too early to make solid informed choices regarding ASP+ until it has been in production. Until then JSP 1.1 is my first choice 75% of the time and ASP 3.0 is my choice 25% of the time. Finally I will also say this (and I have written this in my columns before) The chances are ASP+ will live up to some of the hype. MS has too much at stake for it not to work right. However, I am fairly conservation in the use of technology, since I am responsible for building systems for other people. And this means even though I think MS will deliver quite a bit, I never build on Beta software unless I have no other choice. ASP+ is still beta, JSP is here and now and offers what I need and that is a very important fact in my support of JSP. I know I mention JSP 1.2 , but the reality is that JSP 1.1 already has everything I need and that is what drives my choice. Have a great day.

JSP developer forums...
Hi Anil: I, too, believe that active and useful developer forums are key to the success of these technologies. Traditionally JSP-interest and Servlet-interest have had participation by a number of key developers at Sun, including both people in the specification side and the implementation side; more recently, I think we have not been as present for a number of reasons, and this has been compounded by the success of the mailing list (we are by far the largest active mailing list, and things will just keep getting worse). I agree that we can, should and must do better, and I'll bring up your concerns and suggestions to the appropriate internal groups. In the meantime, some, hopefully useful, pointers: * ALl mailing lists @ java.sun.com also provide a DIGEST format that can be used to reduce mail traffic. * All mailing lists @ java.sun.com provide a Web archive that is sorted by date, thread, author. [Archive is at http://archives.java.sun.com/] * The ASF-related projects keep different mailing lists (-user, -dev, -general, ...). Relevant ASF projects include tomcat (the code basis for the RI), taglibs (an incubator project for JSP tag libraries), struts (an MVC framework using JSP and Servlets). * Different mailing lists hosted by the different vendors. For example, I know that Allaire keeps its own mailing list, although I do not participate there.

Re: Diff bet asp & jsp
Here's an interesting article I found at Oreilly's website that compares J2EE with .NET in general: http://java.oreilly.com/news/farley_0800.html I found the article to be generally informative and avoids the 'heated' rhetoric that often plagues discussions between Microsoft and non-Microsoft technologies. -Original Message- From: Don Makoviney [mailto:[EMAIL PROTECTED]] Sent: Monday, February 12, 2001 5:52 AM To: [EMAIL PROTECTED] Subject: Re: Diff bet asp & jsp Nice reply. . .thanks for the background and bio. -Don Makoviney -Original Message- From: JSP Insider [mailto:[EMAIL PROTECTED]] Sent: Saturday, February 10, 2001 1:42 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Diff bet asp & jsp Good Morning Don, I suppose I should answer this email since you asked me a pretty direct question on my beliefs. Hmm Am I Biased? Let's see and examine this in more detail: I have been programming ASP since it was first released over 3-4 years ago. In fact I still programming in ASP today. I like ASP a lot. In fact ask any of my co workers and they will say I am a fan and supporter of ASP. I have successfully implemented many ASP sites. I still have recommended and am in process of helping start up several new ASP projects. Hmm. Ok. So far so good. Now let's look at JSP I started programming Java at the same time as ASP. And I have been programming JSP for the past year. Again I like JSP alot and again ask any of my co workers and they will say I am a fan and supporter of JSP. Again I have sucessfully implemented JSP sites. Again I am in the middle of setting up JSP projects. In fact I liked JSP enough to start up the JSPInsider web site. Hmm Ok still So far so good all things seem pretty equal. So now I am forced to compare the two platforms BASED ON real expereinces of using each. And I personally find JSP to be a better server side solution most of the time. I am not saying ASP is a bad solution It is great solution. Read what I have written and you will find I am an ASP supporter. But in programming both ASP and JSP I have found from practical experience that JSP is currently the stronger solution. Program JSP for 6 months and then make your own decisions. Don't believe what I say or what others write. In the end it is something you have to decide for yourself. THE TRUTH: JSP isn't for everyone and ASP isn't for everyone. THE SOLUTION Use the solution that is right for you. I just believe and my experience as it now stands JSP is the stronger of the two systems. In a year ASP+ might be the stronger. But you must understand my judgements are based upon hard and true and tried experiences. Killer specs means nothing to me, they are just specs. I have to produce a product and I will use the one right for my customer. So yes I suppose I am biased slighly in favor to JSP due to my successful experiences, But isnt everyone biased?? Obviously you are heavily biased towards ASP+ as I can tell from the strength of your feelings in the email! Is this bad? No of course not, expecially if it gets the job done. If you are living or breathing of course you will have your favorite tool to use, based on the tools you are successful with. The real question is are you open minded and can you be flexible to use the right tool for the right Job! KEEPING AN OPEN MIND And in that I always have an open mind, that is why I build both ASP and JSP web applications, because neither one is right for everyone. However, my experiences and my currently perffered solution is JSP as it offers the most maintainable and easiest to build reusable web solutions. NO amont of BETA specs will change my mind in this since it doesn't count until production, and this isn't a matter of being open minded but realistic. Anyone who builds a house of cards on beta software deserves the house they build, sometimes the gamble wins but more often the gamble loses. I hope your programming path in ASP+ is as smooth as you state it will be. ASP+ is a complete rewrite of the ASP rules and in this I reserve the right to have my have doubts until it has in production for 6 months. Once it has been in production for six months get back in contact with me and ask me how I feel then and please share your experiences for I will be interesting in comparing notes. However, after looking at ASP+ and still working with ASP 3.0 I have decided its too early to make solid informed choices regarding ASP+ until it has been in production. Until then JSP 1.1 is my first choice 75% of the time and ASP 3.0 is my choice 25% of the time. Finally I will also say this (and I have written this in my columns before) The chances are ASP+ will live up to some of the hype. MS has too much at stake for it not to work right. However, I am fairly conservation in the use of technology, since I am responsible for building systems for other people. And this means even though I think MS will deliver quite a bit, I never build on Beta
Re: Off - Topic White Box Testing tool for Java Code
If you're thinking of unit testing (regression, etc...) check out junit (www.junit.org) Also, you might want to look into jython language (www.jython.com - python written in java [my personal favorite]). And of course there is 'JTest' from www.parasoft.com (they have other tools as well). The only issue I have with JTest is that it is not free. There are a number of other tools out there. All really depends on the kind of "white-box" testing you are doing. ..oh, and TETware is also pretty popular ( http://tetworks.opengroup.org/ ) _Ivan p.s. if you're interested in writing test-harnesses/frameworks, I would suggest you use either junit, or jython.. or both :) -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Shahzad Mahmood Sent: Monday, February 12, 2001 5:26 AM To: [EMAIL PROTECTED] Subject: Off - Topic White Box Testing tool for Java Code Hi All, Can somebody tell me about any White Box testing tool available for Java Code.

Re: JSP developer forums...
Eduardo, Thanks for the response.. Glad that we agree that developer support in thesed forums and listserve's are an important way of assuring the sucess of JSP. Hopefully we will be seeing more of you guys here... I hope to hear back from you (hopefully with some implementation details) once the internal group discussions are complete. Thank you also for the pointers...

Re: Session Object Persistence
Hi Dan,
First you should make sure field != null before trying to put it
in the session. That is what is causing the NullPointerException.
Then add a tag inside the
tag. This will add "fieldname" to the list of parameters that will
be preserved and passed to future pages.

Re: JSP Server with IIS
You can download JRun 3.0 from Allaire.com. Configuring it with IIS 5.0 is easy , once you begin installing throught the install wizard you come to a section that says "Connection Wizard" . This section provides a dropdown for the available web server , IIS 5.0 is one of the the options. Select that and set the scripts directory. JRun 3.0 CD was distributed free a few months back with the JavaDevelopers Journal , so if you know anyone who subsribes to that you can get a copy, but its a developer license. Allaire is conducting a free seminar for JRun all over US in the next few months , if interested check their website to find the one nearest to you.

It all starts off with project that I have to do as my final year engineering project. Me and my group contact this company who agree to give us a project. Before that they ask us to learn JSP and do a small program and submit within a week. That was 8 mths ago. After that starts a saga of downloading Apache web server, Tomcat, Java engines...and actually tryin to set them up on my Celeron 466Well 2 mths and a lot of mails, JUGS, Boards later.I finally get JSWDK-1.0.1 up and runnin...then the exam dates are announced.so its bye bye project ..down to the books... I study for my exams and decide that as soon as the exams are over i am gonna dive right into making this small example for the company guyz so that we can at least start the project...but a few days before the exams ..NEWS: Exams postponed.. Well the exams finally got over a month ago. and i get working on a small JSP prog using beans..A month later..here I amfrustruated, depressed...looking for one last hope... If you are wondering where exactly are the other members of my group through all this.beats methe poor ppls proggramming knowledge is limited to a very basic C so even if they wanted to they wouldn't be of very much help. Now I really need to do this project well..because after I finish this I want to work in the same company Its like my dream place to work in.small place..but so much potential for growth So, I need a messiah.. Someone to help me get done in a couple of months what was supposed to have been done over a period of 6 mths... If there is someone out there who is willing to help this poor grasshopper in need...I'll be indebted to them all my life...I'll clean your floors .do the dishes..anything.JUST HELP ME!! === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Session Object Persistence
James,
Here is my current (sample) code I am working with. I
Now do not get a null pointer exception. But now the
first page with the first 10 rows from query come up.
Then when I go to next pages, the counter is there but
no data. Not even rows with null values.
Any ideas would be helpful.
This little thing is causing such a headache!
Thanks for all the help.

Re: Session Object Persistence
The problem is that the url parameter name is "sqlstmt" and
you put instead.

Re: Session Object Persistence
James,
I dont get a null exception any more, however, I am
getting a strange result. I get the first ten. Then
when I go to the 1/2/3/4 etc it is blank, except for
the links. There is no data, not even rows with null
values. Any ideas would help eliminate my headache ;)

Jsp Joe, You will have to do your own work but I can help with some direction. Here is a site with a lot of JSP information including tutorials. http://www.jspinsider.com I would also suggest you read a good book on JSP.

empty promises...And the fact you alienate your group mates shows that you are not a team player.

Re: A little Grasshopper + JSP ???
Joe, We can surely help you out. The softwares you need will be An JSP/Servlet Container A Web Server JDK IDE - an interface for writing java programs , jsps and servlets. You can get the latest JDK from the sun site at java.sun.com , also download the documentation For a web server if you are using microsoft as your platform you can Personal Web Server or IIS. If you want to go with free ware you can get Apache Web server. Finally getting a JSP/Servlet container. There are a lot of containers available for free , most of them also have a specific forum that addresses their installation , troubleshooting and configuration issues. This is a decision you have to make. Some of the popular and easy to configure engines are Tomcat and JRun You can get JRun from allaire web site. JRun as a JSP container can use IIS , Personal Web Server , Apache or you can use JRun without any web server and use JRun itself as a web server. Tomcat is also pretty good. For writing JSPs you can get any free development tool like Forte , Kawa , Homesite . If you don't like to use an IDE directly use Textpad , notepad or any other text editor . There are a lot of sites that have JSP tutorials , visit some useful JSP sites JSPInsider.com , JGuru.com , java.sun.com.products/jsp , coreservlets.com. hope that helps Santosh Jsp Joe <[EMAIL PROTECTED]> on 02/12/2001 01:10:04 PM Please respond to A mailing list about Java Server Pages specification and reference <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] cc:(bcc: Santosh Daryani/IT/Aon Consulting) Subject: A little Grasshopper + JSP ???

Re: Java Date Class problem
Try my code instead, it's proved work. Java Date is an monster, when you
need to move foward and backword of a Date, I usually use Calendar to help
(it has add() method),
You sure can work other way out, but I believe this solution is simple and
handy, also attach another method to add and substract Date. hope this will
help.
Rewrite your code
to -->
<%@ page language="java" import="java.sql.*, java.util.*"%>
<%
java.util.Calendar cal =
java.util.Calendar.getInstance();
cal.setTime(new
java.sql.Date(System.currentTimeMillis()));
int duration = 30; //System.getProperty("myDuration");
use this to store info in property file instead of hard coding
%>
Reservation Date
<%
for(int i=1; i<=duration; i++){
cal.add(Calendar.DATE, 1);
java.sql.Date date = new
java.sql.Date(cal.getTime().getTime());
%>
<%= date%>
<%
}
%>
-->
Bonus method, put in an int to indicate how many days your want to add or
substract from the passing date, if dealing with current, passing Date is
new Date();
--->
public java.sql.Date dateAdvance(java.sql.Date date, int offset)
{
java.util.Calendar cal = java.util.Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.DATE, offset);
date = new java.sql.Date(cal.getTime().getTime());
return date;
}
--->
Good luck.

putValue and getValue methods are deprecated, now u should use setAttribute

Re: Diff bet asp & jsp (end all, i hope.)
Ok, now I feel urged to write (in spite of having this discussion arise every 3 months). Geert, your knowledge base regarding .NET is rather narrow. There are several sites already developed using the newest .NET framework. What 'sucks' is that they are not permitted (as of yet) to publicize as being implementors of it. Why? Because, you cannot implement something that is not fully released. To all, regarding their differences, there is none. It's all syntax. "What?," you say. The explanation is simple: if you look at the structure of both genres of coding, they are both comprised of the same structures up and down from source code to server-side hosting. A variant? The overall syntax and interpretors (aka containers). Which is another difference: terminology. In the end, if you know the functionalities of both languages and their syntaxes and how to implement a site on both platforms, you're set to simply say "they are the same, in the end." Yes, it's the big picture. But, everything I develop in ASP i develop in JSP. All ActiveX DLL/COM objects coded in VB or C++, i recreate in Java Beans. Anything that uses MFC's, I mimic on Java's side. You get the point. ASP can use JavaScript, or VBScript. JSP doesn't support server-side VBScript interpretation. Big deal. They each work best on their respective OSes. WANT MORE INFORMATION? LOOK AT THE ARCHIVES FOR THIS LIST. There has been plenty of discussion months and months ago, on a regularly repeated basis. Instead of telling others to research, research yourself. Merely revert back to the archives. .

Re: Java Date Class problem
the index is not the key of his problem, the date did get mess when index is
greater than 24. That could be a problem related to how he handled the date
object, but for sure, changing index won't solve the problem. The issue is
he do need a way to print whatever many days (future or before) in the list.
My last email is a solution, but certainly there are various ways to do it.

Re: A little Grasshopper + JSP ???
Shawn, I cannot compare because I've never used JBuilder , although in a recent reader choice poll conducted by JavaDevelopersJournal JBuilder was one of the top ranking IDEs , far out ranking Forte. No , I've never used the compile all option in Forte , so really don't know the answer to your question.

Strange JSP Exception
Hey folks:
In our project we're using VA Java and Webshere as our app. server.
Recently I've noticed that while loading one of our JSP's we'vw been getting
a strange exception. What makes it even weirder is that it is a very small
JSP and after we get the exception and it bombs out we can continue to use
it normally. The HTML is only a small form, Here is ALL the java code in
that page:
<%
HttpSession curSession = request.getSession();
if ((request.getParameter("contact") == null) ||
(request.getParameter("contact").equals(""))){
curSession.putValue("contact", " ");
}
else{
curSession.putValue("contact", request.getParameter("contact"));
}
if ((request.getParameter("salesPerson") == null) ||
(request.getParameter("salesPerson").equals(""))){
curSession.removeValue("salesPerson");
curSession.putValue("salesPerson", " ");
}
else{
curSession.removeValue("salesPerson");
curSession.putValue("salesPerson",
request.getParameter("salesPerson"));
}
%>
We have to use JSP 0.91 (DUH!), there's no intrinsic(?) support for the
session built in, and we use JSDK 2.0 (Double DUH!) and JDK 1.1.7, so
session.putValue() is not deprecated. BTW, the session is not timed out.
Here is the exception we get...

Do you have Oracle 8i installed in your system. If then check the classpath and point
it to the Java Classpath.

Re: include problem
If I give a return after the redirect, the common.jsp doesn't display but
the rest of the page that is the page where it is included gets displayed.
The control doesn't go to the login.jsp as I want it to.
I am using JavaWebserver2.0.
Thanks

Re: JSP tags & embedded expressions
I checked the JSP 1.1 specification. Section 2.12.1 defines my example below as a "Request Time Attribute Value" and states it is legal for the value attribute of jsp:param. This is reiterated in section 2.13.6.1. So, based on this I guess the iPlanet Web Server is not fully JSP 1.1 compliant? Any comments / confirmations are appreciated.

JSP-Servlet question...
Hi, Thank you in advance to anyone who maybe able to help me with this query. I am completely new to JSP, however I have been working on Servlets for quite awhile...Here is my query. DESCRIPTION: === I presently have servlets which take input from a client(browser), accesses a database and retrieves information from it to display the output to the user, presently, I am dispaying the output to the user in HTML format. This HTML is written in the servlet code, however, I have learned that I can take the HTML away from the Servlet and instead, "feed" the output from the servlet to a JSP file, which conatins all the HTML for presentation and will also accept the info passed to it by the servlet and include it in the HTML, for display purposes. Basically, how do I develop a situation where a servlet is invoked by a user, but the servlet sends the answer to a JSP file for presentaion to the client. Any help would be really helped.

To forward the request to the JSP, something like this should do the trick: RequestDispatcher rd = getServletContext().getRequestDispatcher(path); rd.forward(request, response); Hope this helps. -- Martin Cooper Tumbleweed Communications - Original Message - From: "Jennifer Feeney" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, February 12, 2001 3:54 PM Subject: JSP-Servlet question... > Hi, > > Thank you in advance to anyone who maybe able to help me with this > query. > > I am completely new to JSP, however I have been working on Servlets > for quite awhile...Here is my query. > > DESCRIPTION: > === > I presently have servlets which take input from a client(browser), > accesses a database and retrieves information from it to display the > output to the user, presently, I am dispaying the output to the user > in HTML format. > > This HTML is written in the servlet code, however, I have learned > that I can take the HTML away from the Servlet and instead, "feed" > the output from the servlet to a JSP file, which conatins all the > HTML for presentation and will also accept the info passed to it by > the servlet and include it in the HTML, for display purposes. > > Basically, how do I develop a situation where a servlet is invoked by > a user, but the servlet sends the answer to a JSP file for > presentaion to the client. > > Any help would be really helped. > > Best Regards, > Jennifer > > _ > > Get your free E-mail at http://www.ireland.com > > === > To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST". > For digest: mailto [EMAIL PROTECTED] with body: "set JSP-INTEREST DIGEST". > Some relevant FAQs on JSP/Servlets can be found at: > > http://java.sun.com/products/jsp/faq.html > http://www.esperanto.org.nz/jsp/jspfaq.html > http://www.jguru.com/jguru/faq/faqpage.jsp?name=JSP > http://www.jguru.com/jguru/faq/faqpage.jsp?name=Servlets === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Kindly Help
Ravi,
This is my HTML code
Simple JSP Program
How Many Times
& this is my jsp code.
<%@ page language="java" %>
Simple JSP Program
<% int numberoftimes = Integer.parseInt(request.getParameter("numtimes"));
for(int i = 0;i
<%= i %>
Hello World!
<%
}
%>
If I don't give ACTION="http://localhost:8100/SimpleJSP.jsp"> in my html it
doesn't execute the
for loop but it invokes the jsp file as it is displaying "Hello World!"
once.
Could you tell me why is this happenning?
Thanks in advance,
Rajeev
