JSP FAQ & Resource Information
This is a weekly informative posting to the jsp-interest list. Before asking questions of a general nature, please check out the resources available online to see if your question already has an answer.

You can download Tomcat from the Jakarta project's website: http://jakarta.apache.org. For feedback and discussion on Tomcat, please use the mailing list [EMAIL PROTECTED] A few notes about the use of this list. We at Sun enjoy hosting this list to give everyone a forum to discuss JSP, servlets and related technology. There are a few things that we ask of you, the list members: Please don't engage in advertising. We like to hear when new products are announced and a link for all the information. What we don't like are lengthy press releases, advertisements, and other material which falls under the umbrella term "marketing". There is no problem in stating how your product compares to another, but remember, this isn't run by Sun to be an advertising forum -- but as a technical forum. Please don't post attachments to the list. The use of VCards and S/MIME is not really needed on a list like this and is annoying to some whose readers don't support them. More serious is the posting of .zip files and other larger items. You might get flamed a little bit for S/MIME or posting in HTML. You will be removed from the list for posting a .zip or other archive file. If you need technical support from a vendor, please contact that vendor directly.

Re: a doubt on sessions
There is always a default session expiry time. This can be overridden by the servlet. There is no way by which the session can be invalidated if the browser is closed. This is not possible using html and servlets alone. If you want to continuously monitor the user, you have to use an applet which "pings" the server at regular intervals or some complex JavaScript and frames. The best solution is the simplest solution (for us programmers!). Put as much resources as possible into the server and don't worry about session expiry etc. or maybe you can implement your own session handling logic using cookies and a database like oracle. In this case, you can dedicate a set of boxes for session management alone and can be isolated from the web server. Is there any third party tool which takes care of these? It would be great and save lots of time and effort.

Re: Opening a word document file through a JSP/servlet
But is it possible to read a .doc file
bcoz I tried to read the file thro a BufferedReader
and it reads the file in chars which in effect gets the wrong data
So when the document opens up it has some illegible characters
I tried the same with a txt file and it was able to read the txt perfectly
The solution could be to read the file in terms of bytes and output the same
to
the client so that the file gets sent to the Word Application uninterpreted
by Java
My Servlet is as
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class CVUpload extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
String str="";
res.setContentType("application/vnd.ms-excel");
//PrintWriter out=res.getWriter();
BufferedReader in= new BufferedReader(new FileReader("c:/Test.txt"));
while((str=in.readLine())!=null)
{
out.print(str);
}
}
}

Re: finally, something interesting!
Hi Everyone,
Instead of creating a public function. It may help to employ "polymorphism"
as it was designed to be. Instantiate the base class and assign it to
the object in use and call the method.
Here's an example code. The output of this code is:
I am the toplevel class.
I am class A
I am class B
// PolyTest.java
// Test polymorphism in java
class Top {
protected void doShow() {
System.out.println("I am the toplevel class.");
}
}
class A extends Top {
public void doShow() {
System.out.println("I am class A");
}
}
class B extends Top {
public void doShow() {
System.out.println("I am class B");
}
}
public class PolyTest {
public static void main( String[] args ) {
Top t = new Top();
A a = new A();
B b = new B();
t.doShow();
t = a;
t.doShow();
t = b;
t.doShow();
}
}

Debugging JAVA/JSP using Sun's Forte for JAVA
Hi, I'm doing some simple development using SUNs free Forte for Java Community Edition. Quite impressed with it so far. My application uses a very thin JSP and uses JAVA classes / Beans on the server for database connections, error handling and as much as possible really. My question is: Can I invoke the debugger to debug my JAVA classes by executing the JSP file? Or am I just better off writing stub classes to execute my server side classes? If this is not possible, can anyone convert an Exception.printStacktrace to a String for me? :) Thanks for your help.

Re: Opening a word document file through a JSP/servlet
I don't think you have to transfer data from word document (that resides on
the server or back end) to word document (for the client) but you might, I'm
not completely sure. I'm sure JSP provides a way to grab the file instead,
perhaps.
What I was working on earlier was generating data (not from another
document) and present it in word in the browser for the client. What you're
trying to do I believe is different.

Re: Question on Imaging
Interesting.. This conversation came up a couple of days ago on an ASP mailing list. Basically, why would you want too? Remember that the JSP file exists on the SERVER, thus the scanning hardware will most likely also have to exist on the server..And if this is the case, why would you need that? You could develop a work around with the client software and some API that you could hook into, but that would be a strict client side situation. Saving the image to the server could easily be done through some Basic file uploader.

Re: Opening a word document file through a JSP/servlet
If you just want to send the Word document to Word on the client then the
simplest way is to redirect to the .doc file. You could also try setting
the MIME type of the response to "application/msword" and sending the
document as a stream of data.
If, on the other hand, you want to extract data from the Word document on
the server, you will have to find a way to use the Word COM or ActiveX
interface from Java. I think it's supposed to be possible with M$ VJ++.
This is all theoretical - I've never done it myself.

Re: Opening a word document file through a JSP/servlet
Hi Thomson,
Well What I want to do is display a document on the server .But I dont want
the URL to be displayed for security purposes, that is why I want it to be
gone thro a servlet. Oherwise it is very easy since If I do a simple
redirect to the file thro a JSP,it opens up the word and solves ur problem,
but displays the URL.
My problem can be solved if I am able in any way to read the file in a
continuous stream format
and in turn stream it to the clients browser then that should th trick, bcoz
otherwise java tries to read the file according to its own interpretation
which destroys the information
TIA

BASE HREF="" with Tomcat 3.2 ?
Hi Am I doing the wrong? I put this inside .. of my JSP. Dosh Tosh Then I wrote .. Now my webapp should run no matter what the context name path is ? The JSP should not care if the webapp is `foobar', `doggone' or `pilgpe' Yet I get a bad connection servlet no found, unless I explicity hard code it .. Is this a TOMCAT 3.2 bug or just me getting it wrong again? -- Peter Pilgrim G.O.A.T "the Greatest Of All Time" -- This e-mail may contain confidential and/or privileged information.

Re: Opening a word document file through a JSP/servlet
Use a FileInputStream instead of a FileReader to read the file, and from your servlet, call getOutputStream instead of getWriter. You almost had it except for the fact that you were using readers and writers.

Using xml with jsp
Hello,
I used this code to parse an xml file:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = factory.newDocumentBuilder();
Document doc = docBuilder.parse(new File("ejemplo.xml"));
Then I modified some nodes but the problem is that I don't know how to save
this changes.

Fw: How to call a remote EJBean from a Servlet/JSP using j2ee server
- Original Message -
From: Mircea Moisei
To: A mailing list about Java Server Pages specification and reference
Sent: Thursday, November 30, 2000 1:32 PM
Subject: How to call a remote EJBean from a Servlet/JSP using j2ee server
Hi all,
I'm back. I think something is wrong somewhere. Let me explain what I'm
trying to achieve.
Reading thru Writing Enterprise Application with J2EE(Monica Pawlan, Sept
27th 2000 ) I build the very first example with CalcBean. After I run in
locally(localhost) using j2ee server from Sun I tried to deploy the bean to
a different machine.
I renamed the JNDI name for the one was locally deployed. I've redeployed
the application made from a web tier( on single Servlet and one single html
file) and the unused session stateless bean on my machine.
I've created a second application made only from the bean described above
and I deployed on the second machine. The JNDI name for second one is
"calcs".
When I'm trying to run it the lookup fails - the name "calcs" given to the
second bean is not visible.
(javax.naming.NameNotFoundException: calcs not found)
Here is the init method where it fails.
public void init(ServletConfig config) throws ServletException{
//Look up home interface
try
{
//InitialContext ctx = new InitialContext();
//new code
Properties p = new Properties();
p.put(Context.PROVIDER_URL, "iiop://ddd.ddd.ddd.ddd:1050");
InitialContext ctx = new InitialContext(p);
Object objref = ctx.lookup("calcs");
homecalc = (CalcHome)PortableRemoteObject.narrow(objref,
CalcHome.class);
}
catch (Exception NamingException)
{
NamingException.printStackTrace();
throw new ServletException( NamingException );
}
}
An additional test I've replace ddd.ddd.ddd.ddd with my IP address and
rename calcs with the name of the "local" EJB and it worked just fine.
I have now some doubts about some security issues(policies) that I have to
take care of.
If anyone had ever a similar problem, please give me a hint to move on.
Thanks.
Regards,
Mircea

JSP contentType setting question in context of jsp:include action
Here's the story...(using JWS 2.0...I know, I know :()
I have a page, call it foo.jsp. Inside of foo.jsp is
Both foo.jsp and fooTable.jsp have
<%@ page contentType="text/html" [etc] %>
When I look at the generated Java source, both
have calls to response.setContentType("text/html").
But despite the fact that fooTable.jsp is called via
a jsp:include action, I get no complaints about it messing
with response headers.
Now the plot thickens...
For various reasons, I want to specify a character set. So
in both cases I change the page directive to
<%@ page contentType="text/html; charset=SJIS" [etc] %>
and sure enough, both generated Java files now have
response.setContentType("text/html; charset=SJIS") in them.
But now an exception IS thrown (IllegalStateException, MIME type
already set) by the server! So I try removing the contentType=
attribute from the directive in fooTable.jsp and I still
get the exception.
Is this a bug with JWS2.0?
And if not, how on earth ARE you supposed to deal with
non-standard charsets when you use the jsp:include
action?

passing hashtables in request
Is it ok to do the following:
JSP A puts all its parameters into "Hashtable myHash". And then it passes
this myHash object to JSP B within a URL such as
"/path_to_JSP_B/B.jsp?parameter1=myHash".
And then upon being called, JSP B does this:
Hashtable passedHash = (Hashtable)request.getAttribute("myHash");
and then enumerates the contents of passedHash.
I am doing this because I need to pass like 100 parameters from JSP A to JSP
B. I am wondering if the above method will create a memory problem.
Thanks for the help

Re: passing hashtables in request
Nope, that's not OK.
You can do what you describe, but not by passing the Hashtable as a
parameter in the URL.
Instead, put the Hashtable in the request
request.setAttribute("parameter1",myHash)
and redirect to the second JSP.
where you can use myHash = (Hashtable)request.getAttribute("parameter1")
Of course, you cannot use response.sendRedirect to go from one page to
another.
You need to use requestdispatcher.include or forward
or the page include or forward tags (which is essentially the same)

Re: problem of passing the request parameters
There are a couple of books on Servlets out there. I forget all the names..but one explains how to read in parameters from a multi-part/formdata post. When you change the way the post is going...request.getParameter() no longer works. Therefore, you will have to manually (in code) extract the parameters in say..a file upload servlet, and then put them BACK into the request before forwarding on. However..I am not sure if you can forward on to a resource using text/html AFTER your servlet gets the multi-part/formdata post. I think you'll have to do a response.sendRedirect in this case..so that you can set the headers in the response back to text/html, which can then go to the browser and BACK to the server using text/html. > -Original Message- > From: Muhammad Asim Ajmal [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, November 29, 2000 11:38 PM > To: [EMAIL PROTECTED] > Subject: problem of passing the request parameters > > > Hi all. > > Currently I'm facing the problem of passing the request parameters > to the next form.

Re: internationalization and localization
Hi Oleg, Thanks for responding. We were trying to use struts library. The only thing I don't like about it is that for every request the action servlet is instantiating (class.forname call) the object and then calls perform method of that object. So, If your action classes are not servlets themselves then every single thread will be using a new instance of that class. In cases where you need to access session beans (EJB) then there is no init method for placing these calls to do only once. That is why we are still evaluating struts but have not made any decisions yet. Let me know if I am wrong.

Only one instance of an action class ever gets created for any particular mapping, and that instance is reused for all subsequent requests -- in the same manner that the servlet container instantiates only one instance of the servlet. A consquence of this is that you must program your actions in a thread-safe manner. > In cases > where you need to access session beans (EJB) then there is no init method > for placing these calls to do only once.

's and JSP's
Ok , here is my problem:
Given: Client is presented with a Form either pure HTML or embedded in a Jsp
page. In that Form there are 20 's and a submit button. Upon
submitting this Form, all those 20 's should be processed.
Unfortunately upto here I cannot change anything. Because it is a customer
requirement.
Problem: I cannot think of a solution which will pick up those 20
's and process them. How can I pass those guys to a Jsp (or a
Bean). The only way possible is:
bla bla
bla bla
bla bla
... till 20
is it OK to send these guys like that and then the reciever JSP will extract
the text from each of the 20 text's by using request.getParameter("text1") ,
request.getParameter("text2") , bla bla
Is there a more elegant way of doing this considering the "given"
constraints.
Thanks...
