Response.End()
Hi, What is the neatest way to an ASP-like Response.End() ? I have an if statement which can cause a redirect and then I want to stop all further processing of the my JSP ... Is it feasible to just call "return null;" since this will return on the service method of the generated servlet - or is there something nicer? Thanks!

Re: Applet and javascript...HELP
Henry, If it is sensitive information, I think the user would feel happier using SSL ? (in which case you don't have to worry about the encoding ...) If you insist on using the applet approach then ... 1) why not hide the form and make the applet call a javascript function to unhide everything when it has loaded? OR 2) Put all the fields on the applet and do a POST from the applet when they hit the applets submit (probably the most work cos you eliminate the HTML form but definitely do-able) Think carefully about your architecture and which approach fits the situation best and will be the easiest to maintain. Hope that helps! :) Jonathan -Original Message- From: Henry Hooi Tak Keong [mailto:[EMAIL PROTECTED]] Sent: 26 October, 2000 8:38 PM To: [EMAIL PROTECTED] Subject: Applet and javascript...HELP Hi all, I'm need to encode certain form fields on my jsp page before submitting it for processing because the information keyed in by the user is sensitive. Does anyone have any recommendations on how I could go about it? To resolve this issue, I have employed using an applet to encode the user's information. The textfields used is still of a html form, and I used javascript to invoke a method in the applet class on the textfields of the form to help resolve this issue. However, that has led me to several problems... 1) I can't seem determine when the applet has fully loaded on the html page because if I press the submit button and the applet is still loading, then the data in the forms will be posted without being encrypted first. 2) I realised that when I use this applet on form fields in a page with frames , it somehow doesn't get loaded properly no matter how long I wait for it to load. When I apply this applet to a page without frames, it loads up almost instantaniously. Any suggestions on how I could resolve this data? I have tried using the tag to help download the applet but I'm confused on how to reference it as an object, in terms of the DOM. Initially, I can reference the html applet tag via document.appletname.methodname. This problem has been eluding me for days already and I really need help. I realised that this may not be a the proper mailing list but I'm sure someone here must have come across these issues before. I couldn't find an applet mailing list from SUN, and if any of you found it, I would be glad if you could pass it on. Thanks everyone.

Re: redirecting servlet page
Deniz, Doing a sendRedirect would not work since the applet is doing a URLConnection to get the data returned. It will just receive the redirect headers - it is not a browser so will not react to the headers ... Why don't you try putting the applet hosting page in the same context so that the user gets the same session id when the applet first loads - then do your login process via the applet and then do a showDocument ... That should work.

Re: How Do I display Java Gui Objects on a browser with JSP?
Charbel, The only way to run Java code on the client browser is in the form of an applet. So you will need to create an applet and you will also need to ensure that the swing classes are installed on the client... You may want to look at running the Sun VM or getting the user to download the JRE 1.3 from Sun which (I believe) includes the swing classes. http://java.sun.com/products/plugin/index.html You may also want to have a good read thru a JSP book to make sure you understand the difference between client (e.g. JavaScript) and server code.

Re: how to detect a browser closing

Heiko,
I went to a week-long Rational OOA&D class and couldn't figure out how to
apply the UML to my web app. So I had a design session with Rational on my
web app and I noticed that the consultants were all peeking in this book. I
asked to see what it was and it was the book that Bill mentioned by Jim
Conallen of Rational ("Designing Web Applications with the UML"). It is an
excellent book. You will also need the Web Application Extensions (WAE) from
Rational's web site for some artifacts to use for server pages, client
pages, etc. Web apps are tough because a servlet for example can manifest
itself as a boundary object by the HTML that it generates (and becomes a
whole different object) and a controller object by nature of it's handling
of HTTP traffic, parameters, and other servlet-type jobs. Conallen provides
a model to handle that nicely. The book also has one of the best tutorials
on the whole web paradigm that I've seen.

Hi,
has anybody ever tried to model a JSP application in UML? I have not
worked very much with UML so far, but I would like to have a means to be
able to design my JSP applications before programming begins.
I think a big modeling problem would be the parameter passing between
servlets and JSPs, which works by storing key/value pairs in request
objects, sessions etc. BTW: I think this kind of parameter passing sucks
anyway, because it is neither type-safe nor is it noticed (by the
compiler!) if you simply don't pass any parameters at all :-( Wasn't
Java said to be a type-safe language? We might as well be programming
Basic...
So, how do you all design you applications? Or are you just hacking away
:-)?

Re: how to detect a browser closing
As far I know this is not possible ... the best you could get would be to use the window_onunload event on the browser to trigger something on the server using say a document.location in clientside Javascript to direct to a server page that just registers that the browser has closed. This is still not fool proof since the window_onunload is not always guaranteed (e.g. if network goes down, or client crashes etc) Remember that HTTP is stateless and there is no communication between the client and server unless the client makes a request.

Re: Passing Session values between ASP and JSP
Daryani,
If you are just saving simple values in the session why not just use
a temporary cookie? Save the values to the cookie from ASP and then
read the values in from JSP. Your session id in ASP depends on the client
having cookies enabled anyway ... so why not?
If there are many values .. then use a cookie dictionary ...
I think this is the simplest solution ...
Cheers,
Jonathan

Subject: Passing Session values between ASP and JSP
Hi All,
I am working on JSPs that interact with another website , where
the
pages are ASPs , I need to get the session values set in a ASP into a JSP.
Session variables work fine between ASP-ASP and JSP-JSP but inter ASP-JSP
communication results in null session variables. I am not sure though , but
I
believe that there should'nt be any problem in doing so.
Can anyone throw some light on this. Your response is appreciated
ASP code
<%
Session("cono")="7719"
%>
JSP code
<%
String cono= (String)session.getValue("cono")
out.println("Value returned from session ="+cono);//results in a null
%>
Thanks in advance
Santosh

Re: JavaScripts : Wanna disable viewing source of the page...
This whole thread seems very silly ... if you need to hide your HTML then you are putting something in there that you shouldn't be ... it is only the presentation layer and will be sent to the client over the network ... if the HTML content reaches their PC (which it must do to be seen) then the unrendered source can be viewed in some way or other no matter what you do.

Re: How to Post Data IN JSP
It seems that it actually depends entirely on the server implementation.
http://x65.deja.com/getdoc.xp?AN=631726939&search=thread&CONTEXT=962117058.1
73080628&HIT_CONTEXT=962117058.173080628&HIT_NUM=2&hitnum=4
I guess the best rule of thumb is that if the querystring is gonna get long
rather use post.

Re: Design choices: JSP & Javascript
Why not use some of Javascript's OO features for example ...
// This javascript client side code should be generated from server side
code
// from your data source
var myData = new Array();
myData[0] = new Array();
var myData[0].name = 'Fred';
var myData[0].dob = '05/07/1950';
myData[1] = new Array();
var myData[1].name = 'Susan';
var myData[1].dob = '05/09/1950';
myData[2] = new Array();
var myData[2].name = 'Joe';
var myData[2].dob = '05/08/1950';
You now have a Javascript object (really just an array) with records
containing properties relating to your data.
You can then use a client-side function to populate a drop-down for example
...
function populateDropDown() {
for (var n=0; n < myData.length; n++) {
var newOption = new Option(myData[n].name);
newOption.value = n;
newOption.dob = myData[n].dob;
mySELECTBOX.add(newOption);
}
}
I like this way of doing this and with a small amount of records being
displayed the
amount of content downloaded to the browser is not excessive.
Cheers,
J

Re: refreshing a frame
Why don't you just do it in JavaScript on the client? ... generate some JavaScript from your server side code, something like: parent.parent.YourFramesName.document.location = parent.parent.YourFramesName.document.location; That way any frame could call another frame to refresh when it is downloaded.

Subject: DB connection problem with NES/Jrun
Hi folks
I'm using NES 3.6 webserver and Jrun 2.3.3 servlet engine.
I'm trying to connect to a oracle database in a remote machine
using JDBC (using Oracle thin driver). I can connect if I run the
program from command prompt. but If I try to run as a servlet
I get an error.
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
[oracle.jdbc.driver.OracleDriver] java.sql.SQLException: No suitable driver
Code :
Class.forName ("oracle.jdbc.driver.OracleDriver");
DriverManager.getConnection("jdbc:oracle:thin:@server-ip:1521:orcl",
"username", "pwd");
I have set oracle.jar (driver) file in my Class path.
Do I need to make some changes in NES/Jrun setup for accessing Oracle DB?
Thanks

Re: How to access environment variables such as "QUERY_STRING"?
Hans,
*** SOLVED!!! ***
Thanks for your advice... I realise it is inefficient to run Java as a CGI
...
it is taking about 8MB of mem a pop (cos of the JVM as you pointed out) ...
Anyway, we have redone it as a J++ COM component (.dll) and are calling it
from ASP which is working far better. (We had to install the MS Java SDK on
the server to get that to work though? - I think it was the WFC that was
needed)
But I did get it working as a CGI (.exe) so I thought I would post the class
I found for getting the environment variables!
I found it here ... all credits to "liquid_isotope" for posting it! :)
http://forum2.java.sun.com/forum?14@@.ee7780f
I have extended it with a parseQueryString method to give me what I needed.
Thanks,
Jonathan

Re: JSP and Javascript
Hi,
Try using the JSP expression syntax ... <%= %>
e.g.
document.location = '<%= response.encodeURL("yourURLwithParamsHere!") %>';
You could probably even add the params you want afterwards ... just use
the JavaScript escape() function to watch out for bad characters.
e.g.
document.location = '<%= response.encodeURL("yourURL") %>&myParam=' +
escape(document.myParam.value);
I don't actually know but I assume the encodeURL adds some Session/URL token
to the URL
that you need to maintain session ... ?
Hope that helps!

Subject: JSP and Javascript
Hi,
is there an intelligent way to combine JSP and Javascript? I want to use
some
entry fields (choices etc.) to specify search parameters in the JSP page;
the
question is: how do I get the values? I have tried to reload the page
with onChange and appended "?param=value", but then I loose my session,
because
I can not use response.encodeUrl from Javascript.
Any ideas?
Joachim
