Problem with getRequestDispatcher()
Hi All,
I am using weblogic 5.1.0 with netscape server 3.6. I have problems using
getRequestDispatcher(), method. No error at the weblogic and netscape log files,
it is compiling the jsp file and creating
myserver/classfiles/jsp_servlet/_jsp/_confirm classfile under weblogic directory,
but the netscape displaying just the html tags as if it is a text file, IE is
saying page cannot be displayed,
The code is like this,
getServletConfig().getServletContext().getRequestDispatcher
("/jsp/Test.jsp").forward(req, res);
It is working fine with weblogic 4.5 and netscape server 3.6.
Please some one help me.
Thanks in advance.

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: session
hi Alber..
i have try the method you mentioned,and it really works.:)
but i get a question about the sequency of the method run.i code a servlet includeing
HttpSession session = HttpServletRequest.getsession();
session.putValue("listenerobjcet",listener);
HttpSessionBindingEvent sessionbind = new HttpSessionBindingEvent(session,"listener");
session.removeValue("listener");
listenerobject is a instance of the class implements HttpSessionBindingListener.
but i found the valueBound( ) and valueUnbound( ) are both called when i run this
servlet.
why the valueBound ( ) method is also called ? The method putValue ( ) is coded before
the Constructor
of HttpSessionBindingEvent .:))

Jsp engine compatible with Domino
Hi , I'm really interesting in using JSP technologie but as i' m a beginner i need some help in the architecture i have to build. I'm obliged to use domino web server but which JSP engine could i add to ? I tried GNUJSP but is not strong enough, in fact too slow. TomCat is also complex and i didn't find some clear explanation to use it with domino. The last, WebSphere seems to be the best one but a bit complex to use... So does it exist other jsp engine compatible with domino, strong and quick ? Or if not, for the others i mentioned, where could i find some clear tutorial ?

Once the response goes back, the thread is freed up as well as any data (objects) created during that request. HOWEVER, there is one instance as far as I know..that can keep objects around after a request. The only thing that I know of is if you put an object in the request that has another reference to that same object in a longer scope. For example, if you store an object in the HttpSession or ServletContext, and put that same object in the request (say before forwarding to a JSP page or something), it will reside in memory until ALL references to the object are nulled out. In this case, if you have an object that has a reference to it stored in the HttpSession (or ServletContext) AND you have a reference to that object stored in the request object, then the actual memory will stay in use until the httpsession expires or you remove the object from the httpsession (or ServletContext). The GC won't do its thing until it can, so even though Java handles memory for you, you still have to do your part in making sure all references to an object in memory are nulled out. -Original Message- From: Jim Huffsmith [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 06, 2000 1:34 PM To: [EMAIL PROTECTED] Subject: request object system memory (again) (I posted this question yesterday, but our ISP went down right afterwards.

The JSP page can access the form params any number of ways but typically

As you showed the above example with %%, I thought about the bottom
one, but with one little difference. I'd rather write
jsp:useBean id="FormHandler" class="xyz" scope="request" /
jsp:setProperty name="formHandler" property="*" /
Note the '/'s at the end of tags.
I think in this particular situation the bean will live only during a
request, so it doesn't matter where jsp:setProperty is. Am I right ?

I had posted a message a few days back but got no response. This is urgent. please help.thanks. I m using jrun as my servlet/jsp engine. in my jrun settings, i have given the java compiler as c:\jdk1.2.2\bin\javac.exe. when i give a request from my browser to the jsp page, it builds the corresponding .java file for the servlet. but when it tries to compile the .java file to .class file, there is an error reported to the browser: 500 internal server error usage:javac options source file and a listing of all the options for javac command. This is the usual message u get if u type just javac from ur command prompt. But when i compile the .java file manually from command prompt, it creates the .class files and subsequently when the jsp is requested from browser, i get the expected page. i think some setting for jrun i have missed. somebody using jrun, please help me out. thanks in advance.

this is the question: if I set a javabean property to null in a jsp page,
it seems the bean does not call the related method.
Let's suppose a bean contains: public void setPropertyName (String in_par)
{ propertyName=in_par; };
if I put into jsp page: jsp:setProperty name="bean_id"
property="propertyName" value="" /, the bean does not call the method
setPropertyName;
if I put into jsp page: jsp:setProperty name="bean_id"
property="propertyName" value="*" /, the bean does call the method
setPropertyName;
but if do I need to empty the property "propertyName"?
any suggestion is welcome
Thank you all in advance

Re: Concurrent access to a file
Jamel Tayeb wrote:
Hi Everybody,
I want to read a configuration file from my Jsp application but I am
having problems that I suspect are due to concurrent access to this
file by multiple instances of the application.
Does anybody know how to avoid conflicts? Will putting the code
in a method that is declared synchronised solve the problem and
guarantee safety? When two instances of a synchronised method
(belonging to the same class) are executing, does the servlet engine
detect and coordinate their execution?
Concurrent access to the web resource is natural in JSP/Servlet
environment. You can't rely on a servlet class that all information
stores in its instance variables, if you do, you're asking for a
trouble. To avoid conflicts you have to queue all the requests and run
them one by one or just put the "sensitive" code inside synchronized
block.
In your particular situation, you caould create a helper class, e.g.
SaveFile. One of the methods could be save() and to create an instance
of the class, you'll have to call getInstance(). It decreses time to
prepare file and do any file-related tasks. So, your code would look
like:
public class SaveFile {
private static SaveFile instance = null;
public static SaveFile getInstance() {
if (instance == null)
instance = new SaveFile();
return instance;
}
private RandomAccessFile raf = null;
private SaveFile() {
// open file
// do something...
}
public void save() {
synchronized(raf) {
doSomethingWithRaf();
}
}
}
You may also define save function as synchronized in the above snippet
since you synchronizes all function's code, so actually whole function.
Now, inside your JSP code (actually it should be invisible for HTML
developer, so I'd suggest that that code should move to servlet or some
other Tag), you'll write
%
SaveFile saveFile = SaveFile.getInstance();
saveFile.save();
%
Actually, you could also put SaveFile object inside session, so the
following servlets/jsps would use it without a need to call
getInstance() method.
Hope, you've got an idea.

Re: Bea Weblogic
From: JSP Insider [EMAIL PROTECTED] Reply-To: A mailing list about Java Server Pages specification and reference [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Bea Weblogic Date: Thu, 7 Sep 2000 00:47:10 GMT I am looking into setting up a Mid sized JSP project and the customer is considering using Bea's WebLogic Platform. I have a really basic question of: Does it come with its own Java IDE (if so what is it called) or do you use a third party IDE with it. If you use a third party IDE, which one would work best? It doesn't come with an IDE. Bea owns Visual Cafe now but it may not be great still. JBuilder works with WebLogic fine. I use the ColdFusion editor to edit jsp's and ejb's which is also fine since the ide's still don't handle debugging very well. And Most importantly Also From the People using Bea, do you recommend it with JSP? WebLogic is a great JSP and EJB engine. If all you are needing is JSP support, you may not have to go as "high end" as WebLogic. WebLogic is bucks. I know these are basic questions, but I am trying to work my way around the marketing hype and get a honest appraisal and see what the developer community has to say.

Re: Question regarding JSP and HTML forms
The difference bewtween
jsp:useBean
jsp:setProperty
/jsp:useBean
and
/jsp:useBean ... /
/jsp:setProperty /
is that in the first case the setProperty only gets called when the bean is
created, whereas in the second case the setProperty is always called. I
prefer the first case for a number of reasons -
I can't accidently do this
jsp:useBean /
% use the bean %
jsp:setProperty /
It gives me better 'encapsulation', I'm sure the bean is fully constructed
before using it, etc.
You pays your money and you takes your choice.

As you showed the above example with %%, I thought about the bottom
one, but with one little difference. I'd rather write
jsp:useBean id="FormHandler" class="xyz" scope="request" /
jsp:setProperty name="formHandler" property="*" /
Note the '/'s at the end of tags.
I think in this particular situation the bean will live only during a
request, so it doesn't matter where jsp:setProperty is. Am I right ?

That's what I've said, but I've also said that in "scope=request" case it *does not* matter which one to use. That's because every time a request comes to a JSP page, a new bean is created (scope="request"). Therefore, both are the same as long as we use "request" or "page" scope.

Re: Problem with if statement
Aaron,
I think you have to use something like this:
if (key.equals("AT"){
...do something...
}
because (supposed) key is a string.

Re: Problem with if statement
Comparing String with == operator does not work. In such a comparison only
the references are checked for equality rather than the values. In order to
check for equality based on value try
if(key.equals("AT")){
}

Re: Problem with if statement
Hi,
You better use:
if (key.compareTo("AT")==0) since compareTo methods compares the string
value but .equals compares objects.

Re: session
Correction,
The following JSP statement
jsp:useBean id="MyListener" scope="session" class="MyBindingListener" /
wouldn't work as it because the class example I gave did not contain a
default constructor.
The correct way is to:
1. Add a default constructor
2. Add a setter/getter method for ServletContext
3. Use the usebean tag in conjunction with the setProperty tag.

Subject: Re: session
Hi
You can do the following:
1. Create a class implementing the interface:
import javax.servlet.*;
import javax.servlet.http.*;
public class MyBindingListener implements HttpSessionBindingListener {
// Save a reference to your ServletContext assuming you put your
// Database connection pool there.
ServletContext context;
public MyBindingListener(ServletContext context) {
this.context = context;
}
public void valueBound(HttpSessionBindingEvent event) {
HttpSession session = event.getSession();
DBConnectionPool = (DBConnectionPool)context.getAttribute("DBPool");
DBConnection connection = pool.getConnection();
Statement statement = connection.createStatement();
statement.executeInsert("Recording start of session for " +
session.getId());
connection.close();
}
public void valueUnbound(HttpSessionBindingEvent event) {
HttpSession session = event.getSession();
DBConnection connection = pool.getConnection();
Statement statement = connection.createStatement();
statement.executeInsert("Recording end of session for " +
session.getId());
connection.close();
}
}
2. Add the object to your session:
HttpSession session = req.getSession(true);
session.setAttribute("MyListener", new
MyBindingListener(getServletContext());
Alternatively if your adding it using JSP:
jsp:useBean id="MyListener" scope="session" class="MyBindingListener" /
3. That's it. Behind the scenes the following events happens in the
HttpSession:
public void setAttribute(String name, Object value) {
// Remove the attribute if it already exists
// store the attribute in the session (generally it's a hashtable)
// if "value" is an instanceof HttpSessionBindingListener
// call it's valueBound method
}
public void removeAttribute(String key) {
// Retreive the object from session (eg. hashtable)
// Remove the object from the session
// If the object is an instance of HttpSessionBindingListener
// call it's valueUnbound method
}

Consider using

When a session is invalidated (either the user

their session timed out)
and is about to be removed, the servlet container
iterates through the
contents of your user's session, calling
HttpSessionBindingListener.ValueUnBound on any
objects in the session that
implement the HttpSessionBindingListener interface.
So, in your case if the user does not log out, then
their session will
eventually expire. When that happens, if you put an

ValueUnBound method get's
called. Within this callback, you can do your JDBC

On the close out question. You can use Javascript,

I'd suggest that any Java code puts either in Tag Extensions or
servlets. Going even a little further, try to follow Model 2 ideas.
Create *one* servlet controller which controls who should do what. In
that case, all JSPs do is only to display beans' state.
To answer your question(s), just put it inside servlet controller, so
the following JSP pages can use it. After that, just forward request to
JSP to display it. When you becomes more familiar with that approach,
you won't have to search all your code, just to check out whether
everything is right. All you'll have to do is to open *one* servlet
controller and modify it as you wish.
Simple ? Yes, it should be:)

Re: Problem with if statement
It's Java101, not JSP at all!!! You are comparing 2 objects instead of
comparing to content.
Use key.equals( "AT" ) and not the == and start to look at the

No. JavaScript is client side..it operates in the web browser. JSP is a server-side technology. You can use scriplets to return dynamic content, including dynamic inline JavaScript code, but you can't use JSP pages once the response (the JSP page contents) has been sent back to the browser. Only JavaScript can be used.

Hi, there have been many questions on this list recently about basic JSP/Servlet programming, that are nicely addressed by an available text: core servlets and javaserver pages by Marty Hall of JHU/APL. Especially useful is is appendix A, which is an outline of programming technqiues for JSP/Servlet programming, somewhat like an exam cram sheet, but for something useful. For those of you too cheap to buy this book, some of the content is available in his tutorial web page: http://www.apl.jhu.edu/~hall/java/Servlet-Tutorial/ But if you are making your living at this, buy the book, it will pay for itself quickly. Also of use is the text:Web Development with Java Server Pages by Duane K. Fields, Mark A. Kolb (Paperback ) for it's useful coverage of the WAR application packaging format in a chapter entitled "The Art of WAR".

File retrieve using HTTPS connection
Sorry for posting this question on the JSP list , this is not a very JSP
specific issue , but I am running out of resources , thought someone on this
list may have an answer. Appreciate your responses.
I am trying to retrieve a file from a https connection, while doing so I get an
access denied error. I have verified the userid and password , they are correct
because I am able to post a file on to the same location with the same user id
and password. The file extension is .log and my content-type has a value of
text/html , but I have'nt had success in changing the Content-type.
This is my code
URL url = new URL("https://file location");
URLConnection urlC = url.openConnection();
HttpsURLConnection theConnection = (HttpsURLConnection)urlC;
// Print info about resource
for (int i = 0; i 10; i++)
{
String headerKey = theConnection.getHeaderFieldKey(i);
System.out.print("HeaderKey " + i + ": " + headerKey);
System.out.println(" Value: " + theConnection.getHeaderField(i));
}
// Copy resource to local file, use remote file
InputStream is = urlC.getInputStream();
// Get File Name
StringTokenizer st = new StringTokenizer(url.getFile(), "/");
String fileName = null;
while (st.hasMoreTokens())
{
fileName = st.nextToken();
}
FileOutputStream fos = new FileOutputStream(fileName);
int oneChar, count=0;
while ((oneChar=is.read()) != -1)
{
fos.write(oneChar);
count++;
}
is.close();
fos.close();
This is the output

I am trying to do something based on if key is equal to "AT", but I am not
getting any results. It acts as if key is not equal to "AT", but I can use
out.println(key) get "AT". Does anyone know why this might not be working?
if (key == "AT") {
..do something...
}
thanks,
Aaron

Re: Book reccomendation: Core Servlets and Java Server Pages by M . Ha ll, addresses most of the FAQs on this liist.
I would second Andy's recommendation for buying Core Servlets and Java Server Pages. There's even an example of an online store that uses a shopping cart and session tracking, online travel agent, embedding applets, using JDBC, and creating custom tag libraries. It also talks a little bit about Tomcat, JSWDK, and JWS, HTML Forms, and JavaBeans. I highly recommend it. -Richard -Original Message- From: Andy Purshottam [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 07, 2000 2:03 PM To: [EMAIL PROTECTED] Subject: Book reccomendation: Core Servlets and Java Server Pages by M. Ha ll, addresses most of the FAQs on this liist. Hi, there have been many questions on this list recently about basic JSP/Servlet programming, that are nicely addressed by an available text: core servlets and javaserver pages by Marty Hall of JHU/APL. Especially useful is is appendix A, which is an outline of programming technqiues for JSP/Servlet programming, somewhat like an exam cram sheet, but for something useful. For those of you too cheap to buy this book, some of the content is available in his tutorial web page: http://www.apl.jhu.edu/~hall/java/Servlet-Tutorial/ But if you are making your living at this, buy the book, it will pay for itself quickly. Also of use is the text:Web Development with Java Server Pages by Duane K. Fields, Mark A. Kolb (Paperback ) for it's useful coverage of the WAR application packaging format in a chapter entitled "The Art of WAR". Looking forward to reading about stuff niot in these fine books on this mailing list, Andy ([EMAIL PROTECTED]) === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Me too. I have been using it for a few weeks. It also has a nice section on JDBC too. http://www.coreservlets.com/ Another good one is Professional JSP from WROX.

Re: Problem with getRequestDispatcher()
I am using weblogic 5.1.0 with netscape server 3.6. I have problems using
getRequestDispatcher(), method. No error at the weblogic and
netscape log files,
it is compiling the jsp file and creating
myserver/classfiles/jsp_servlet/_jsp/_confirm classfile under
weblogic directory,
but the netscape displaying just the html tags as if it is a text
file, IE is
saying page cannot be displayed,
The code is like this,
getServletConfig().getServletContext().getRequestDispatcher
("/jsp/Test.jsp").forward(req, res);
It is working fine with weblogic 4.5 and netscape server 3.6.
This looks to me as a MIME/Content-Type issue. The HTTP response is having
text/plain as Content type.
Check whether u have a MIME-TYPE or Content-Type set for .jsp file suffix.
This you can
check throgh ur Netscape Admin. Go to ur Netscape instance admin screen and
click on MIME Types
link under preferences TAB. Now check for text/html content-type and the
file suffix's it is
associated with. If you dont find jsp add jsp. Now apply changes, bounce NES
instance and try again.

Re: Reading Context Params from web.xml

You can access it from servlet and JSP.
For e.g.
context-param
param-nameidleTimeout/param-name
param-value30/param-value
/context-param
From Servlet:
String idleTimeoutValue =
getServletContext().getInitParameter("idleTimeout");
From JSP:
% String idleTimeoutValue = application.getInitParameter("idleTimeout"); %

Re: session
Hi Laskowski,
As I understand , one uses JSP over Servlet because writing a JSP code is simpler
compared to Servlet.Right ?
They are 2 different server side technologies.
I agree that JSP finally compiles into a Servlet.But , i don't understand why one
will use JSP and servlet together ?
When you use JSP , all the objects like request , session... are available
implicitly which you get in servlet by extending HTTPServletRequest class. right ?
So why one will use Servlet with JSP? As I understand one uses Java code in a
separate bean because he/she wants to hide the business logic. Right ? Why to keep
the same code in a servlet ?
Is my thinking correct or am i missing here something ?
Thx in advance
Rakesh.

thanks for your reply :)
i am very new to this concept. Is there anywhere that
i can learn a little bit more about this? I've notice
that Tomy Wong has put some code on his reply:
HttpSession session = HttpServletRequest.getsession();
session.putValue("listenerobjcet",listener);
HttpSessionBindingEvent sessionbind = new
HttpSessionBindingEvent(session,"listener");
session.removeValue("listener");
I don't know where to put this code, is the jsp page,
or in the bean? If in the jsp page, is it on every
page? How do i set the length of time for the
time-out? I am getting little confused. Please help
me out!
I'd suggest that any Java code puts either in Tag Extensions or
servlets. Going even a little further, try to follow Model 2 ideas.
Create *one* servlet controller which controls who should do what. In
that case, all JSPs do is only to display beans' state.
To answer your question(s), just put it inside servlet controller, so
the following JSP pages can use it. After that, just forward request to
JSP to display it. When you becomes more familiar with that approach,
you won't have to search all your code, just to check out whether
everything is right. All you'll have to do is to open *one* servlet
controller and modify it as you wish.
Simple ? Yes, it should be:)
