about jsp:include
hi everybody:
same sample as last quesion.
is it ok if i change the element of "%@ include file="response.jsp" %" to
jsp:include page="response.jsp" flush="true" /? it works wrong in my
server. it is like my server do not the element of "flush". and it tell me
"com.sun.jsp.JspException: "Include: Invalid attribute, flush"". if i take
it out, the first page is ok. but whatever i type in the text, the server
response the error of "com.sun.jsp.JspException: Unable to compile class for
JSP: null". i want to know the difference between these two elenents.
thanks for your help.

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.

If you do not want to use the session object to store the date, a solution could be to get the data in A.jsp and then set them in the src as request param to get them in b.jsp : b.jsp?param=val Or you could also, group all yout data in a bean and only save the bean in the session to be able to get these data from any jsp files and once you get your bean you can destroy it from session object if you want to be sure to not use these data several times.

Subject:Re: JSP and Javascript
Hi,
Try using the JSP expression syntax ... %= %
e.g.
SCRIPT LANGUAGE="JavaScript"
document.location = '%= response.encodeURL("yourURLwithParamsHere!") %';
/SCRIPT
You could probably even add the params you want afterwards ... just use
the JavaScript escape() function to watch out for bad characters.
e.g.
SCRIPT LANGUAGE="JavaScript"
document.location = '%= response.encodeURL("yourURL") %myParam=' +
escape(document.myParam.value);
/SCRIPT
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!

public class ConnectionPoolAsSingelton {

Re: Connection Pool
Hi Sanjay,
you can avoid the problem by using the double-checked locking pattern
(Schmidt-Harris) as follows:
public static ConnectionPoolAsSingelton getInstance() {
// check for null singleton
if(instance==null)
{
// obtain lock
synchronized( this )
{
// check for null again in case initialization
// already occurred in another thread
if(instance==null)
{
return new ConnectionPoolAsSingelton();
}
}
}
else
return instance;
}
the synchronization overhead is limited by the first null check,
so that further calls to the method never reach the synchronization code
and its associated overhead.
Regards,
Jin

Re: Request.getParameter
request.getParameter() returns a String, so the toString() call is
unnecessary. It is also dangerous as request.getParameter("var") may return
NULL if "var" was not a form element in the submitted form, or if it was an
unchecked Checkbox or Radiobutton.
from
http://java.sun.com/products/servlet/2.1/api/javax.servlet.ServletRequest.ht
ml#getParameter
"public abstract String getParameter(String name)
Returns a string containing the lone value of the specified parameter, or
null if the parameter does not exist."

Thanks, but I *also* scoured the spec. What parts of the spec answer my
question?
I don't know what the previous poster does, but you are correct that
there is no direct support for authentication in the Servlet spec.
What we do in our Model 1 apps (the simplest case) is rely on FORM-based
authentication, tracking a successful authentication via methods in a
bean that we store in the user's session. Our "normal" pages have
something like:
jsp:useBean id="userbean" scope="session" class="com.blah.UserBean" /
% if( !userbean.isAuthenticated() ) {
response.sendRedirect("login.jsp");
}
%
HTML
. . .
The isAuthenticated method of UserBean checks a boolean as to whether
the user successfully logged in or not. If this flag is not set, we
redirect the user to the login page. The login page looks something
like:
HTML
% session.invalidate(); /* nuke any prior session information */ %
BODY
FORM ACTION="login2.jsp" METHOD="POST"
Username: INPUT TYPE="TEXT" NAME="user" SIZE="18" MAXLENGTH="18"
BR
Password: INPUT TYPE="PASSWORD" NAME="password" SIZE="18"
MAXLENGTH="18"
BR
INPUT TYPE="SUBMIT"
/FORM
/BODY
/HTML
When the user presses Submit, they are sent on to login2.jsp, which
performs the authentication check and, if successful, forwards on to the
main content page --
@ page contentType="text/plain" buffer="16kb"
errorPage="loginError.jsp" %
jsp:useBean id="userbean" scope="session" class="com.blah.UserBean" /
jsp:setProperty name="userbean" property="*" /
% // The above setProperty should have called setUser(...) and
setPassword(...)
// which will allow us to attempt authentication. If we fail
authentication,
// the bean will throw an exception, which will bounce us over to
// the indicated errorPage above.
// If successful, this method will set the authenticated flag to
true.
// If not, it will set authenticated to false and throw an
exception.
userbean.authenticate();
// If we get this far, we must have succeeded. Let the user in to
our app.
// Note that we use encodeURL here to handle cookie-less sessions.
response.sendRedirect(response.encodeURL("app_page1.jsp"));
%
The app_page1.jsp would include the check shown at the top of this
email. loginError.jsp would display the error message from the
"exception" implicit object and then give the user a link to bounce back
to login.jsp.
There are more efficient ways of implementing the above, particularly
ways that use jsp:forward rather than browser redirects. I think the
above is the most straightforward to get folks started, though.
And, more generally, what parts of
the servlet API are accessible to my code when I'm using JSP?
All API
How?
First, you have access to the implicit objects defined in the JSP spec
(there is a cheat-sheet for download at http://java.sun.com/products/jsp
that lists these):
request javax.servlet.http.HttpServletRequest
response javax.servlet.http.HttpServletResponse
pageContext javax.servlet.jsp.PageContext
session javax.servlet.http.HttpSession
application javax.servlet.ServletContext
out javax.servlet.jsp.JspWriter
configjavax.servlet.ServletConfig
exception java.lang.Throwable
Second, you can access ANY Java class inside a scriptlet:
% com.blah.MyUtilityClass utils = new com.blah.MyUtilityClass();
utils.doSomething(request,response);
%
as long as the class is accessible along your Servlet Engine's classpath
(configuring your servlet engine's classpath is vendor-specific --
consult your vendor documentation or visit one of the product-specific
support pages or email lists).

Re: User Authentication
One method I've used fairly successfully is to let the webserver do the authentication -- this allows your site to be added to other sites and rely on their authentication. All I do is turn on the built-in auth for the web server, and it takes care of sending a WWW-Authenticate header to users who don't yet have an Authenticate header in their requests. Of course, the basic auth is simple user/pass using crypt, but various servers offer different auth methods such as client-side certificates, etc. With something like Apache, you can even write your own DSO authorization add-in. In order to cut down on admin tasks, I also generally automate the new user creation -- the error link for unauthorized access attempts causes a redirect to an unprotected new user creation site, where users step through a wizard that gathers their info. Once the info has been gathered, I create a user entry (on Apache, I exec the htpasswd command in a JSP) and then redirect the user to the page they originally tried to hit. Once a user successfully enters the site, I use the remote username as a lookup key to get the user's personalization info. _3 M === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

There are many techniques to do user authentication at the application level, that have been discussed often on this mailing list. I'd like to focus here on the meat of your question -- what does the servlet container do for me? There are four things that need to happen for the stuff in the spec (as described below) to provide container-managed security for you. * You have to be running a servlet container based on the version 2.2 (or later) specification for anything described here to matter. There was no standardized support in previous versions. * The 2.2-compatible servlet container you are running on must support the security features of the spec. Check the documentation on your servlet container to make sure. * You must define one or more security-constraint elements, plus a login-config element, in your web application deployment descriptor. The security-constraint element describes what URL patterns (within your app) should be protected, and what "roles" a user must possess to access those resources. The login-config element describes how you're going to perform authentication -- for example, you can choose HTTP BASIC authentication by including auth-methodBASIC/auth-method inside. See Section 11 of the spec for much more about security. * You must register your usernames and passwords, and their associated role assignments, in the users database for your container. How you do this is different for every server -- again, check the docs. When you do these things, the servlet container enforces the authentication and access control restrictions you've defined, and you can use the security related calls on HttpServletRequest (getRemoteUser, getUserPrincipal, and isUserInRole) to find out more information about who was authenticated. And, more generally, what parts of the servlet API are accessible to my code when I'm using JSP? All API How? Every JSP page gets compiled into a servlet. Therefore, the generated code can do anything a servlet can. For example, the "request", "response", and "session" implicit objects that your page can access are instances of HttpServletRequest, HttpServletResponse, and HttpSession respectively -- therefore, these objects have all the methods defined in the servlet API. --johnt Craig McClanahan === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

The jsp:useBean action places a reference to the bean in the specified scope, or the page scope by default, using the name specified by the id attribute. So your custom action could look something like this: foo:myAction name="bean" ... / The name attribute specified the name of the bean you like to use, and your custom action implementation can search for it in all scopes using the methods of the PageContext class (always available to a custom action). If the custom action can deal with beans of different types, it can use "if (theBean instanceof AClass)" tests to do different things depending on the type of the bean, or use introspection to look for required methods in the bean, etc. What's right here depends on what the custom action is designed to do.

long to date?
I'm trying to use file.lastModified() to get the last mod date of a file
and then print on the screen as a string. The problem is it looks
like lastModified() returns a long? Do I have to covert my long to a
string and then use SimpleDateFormater to format it how I want or
is there a way to go right from my long to the date format I want?
Here's what I would like to do:...
%
String logFileDate = null;
File logFile = new
File("/app/webdocroot/insidectm/logs/coxdirect/2000/cdcor2000repo
rt.htm" );
if( logFile.exists() )
{
DateFormat df = new SimpleDateFormat( "dd-MM-" );
logFileDate = df.format(logFile.lastModified());
}
%
any help greatly appreciated.

Re: Model 2 and multi-page techniques
I'm reposting this with a different subject heading, since I got zero responses from my first posting. I've seen so many messages from people that were replied to quite quickly, I guess I've come to expect the same. Hopefully the new subject line will prompt others to read/respond Thanks, Mike All: Govind Seshadri had an excellent article on advanced form processing located here: http://www.javaworld.com/javaworld/jw-03-2000/f_jw-0331-ssj-forms_p.html Other posts to this list have talked about multi-screen (page) forms, e.g. a wizard type interface with back/next/finish/cancel buttons. I'm having a little trouble envisioning how this would all fit together. Using Govind's article as a baseline: * Would multiple forms/pages require a different validation bean for each page? (This assumes that you want to validate the user's input on a per page basis, rather than, or in addition to, when he/she chooses the finish option.) * Choosing the finish option would (naturally!) post to the UserRegistration.do according to good model 2 design. Is it OK to have the back/next "events" directly navigate to the previous/next .jsp page? (I don't want to have to create UserRegistrationStepOne.do thru UserRegistrationStepTen.do! (Do I?) * Finally, doesn't this lead to too high a degree of coupling between the view the controller(s)? Or, what I mean is, haven't we prevented our page designers from exercising their creative freedom to place which fields on which form, since that will always require "back-end" coding changes?

Re: Model 2 and multi-page techniques
Hi, I'll try responding. ;) * Would multiple forms/pages require a different validation bean for each page? (This assumes that you want to validate the user's input on a per page basis, rather than, or in addition to, when he/she chooses the finish option.) Actually, I prefer client-side validation using JavaScript. I have seen some people say to do both or server-side, but frankly, client-side eliminates the need for server cpu cycles to validate entries. If you validate them properly on the client with JavaScript, you know they are correct when they get to the server. I think the exception is if during trasit something gets messed up, a lost packet or something. I have never seen that happen and am pretty content with using client-side validation. But, if you were to do server-side, I would definitely use page per page validation! Imagine 4 or 5 forms and your sent back to form 1 because of one bad entry. Then you have to code in on that page a "finish" button, and on every page, for that matter, so that they dont have to submit the other forms that may be correct. I would break it in to an action class per page, and if you have multiple actions for a complete set of forms, they can still all reference the same one entity class (JavaBean most likely..or EJB). By storing the entity in the HttpSession, it stays alive all throughought. Then at the end, you process the data, store it, whatever, then remove the bean from the HttpSession. * Choosing the finish option would (naturally!) post to the UserRegistration.do according to good model 2 design. Is it OK to have the back/next "events" directly navigate to the previous/next .jsp page? (I don't want to have to create UserRegistrationStepOne.do thru UserRegistrationStepTen.do! (Do I?) I do. I have a JSP page per form that is to be displayed. And I have an action per form. You can have multiple forms submit to the same action, but then you'll need some sort of hidden command code system to figure out the specific action to take. However, usually no processing other than validation and storage in the bean and display the next page is done between steps. Not always the case though. For example, on our site clients choose an option, and depending on which option they choose, the next page reflects that option. Not necessarily the page name or anything (although that certainly can be done too). * Finally, doesn't this lead to too high a degree of coupling between the view the controller(s)? Or, what I mean is, haven't we prevented our page designers from exercising their creative freedom to place which fields on which form, since that will always require "back-end" coding changes? Ideally your web person can use Taglibs (JSP 1.1) or JavaBeans in any way he/she likes. For example, as I said even if you use one action per form, you would most likely use the same JavaBean amongts the different action classes to store all the form input (and output), so that each of the JSP pages use the same bean for display as well. Thus, unless the name of a method or property was changed on the back end, the web developer pretty much has the freedom to move the dynamic content around at will. Its more likely (I think) that the developers would make changes and tell the web folks the change and not the other way around. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

JSP equivalent of JHTML SERVLET/SERVLET

Re: JSP no-cache problem on IE 5
Cant remember where i read this but it works for me
Apparently IE5 has a bit of a browser caching bug.
If I have the following meta tag at the very bottom of my html it fixes my caching
problems. In the document I read it said that if the meta tag isnt at the very bottom
of the page then it doesnt work. After fooling around I tend to agree.
meta http-equiv="Expires" content="0" url="a description here"
/html
Also - the tag wont work if you include the other caching tags in your HTML.

IF your using JSP 1.1, you can do the jsp:include page="/servlet/com.package.Servlet" jsp:param name="name" value="value" / /jsp:include to include params like you can in the servlet. JSP 1.0 did not support the jsp:param.. tag. Tomcat and Resin both support Servlet 2.2, JSP 1.1, so you should be good to go there. -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Rich Carreiro Sent: Thursday, April 13, 2000 2:53 PM To: [EMAIL PROTECTED] Subject: JSP equivalent of JHTML SERVLET/SERVLET I am dealing with some JHTML pages (stuff parsed with the Sun-provided pageCompile servlet that shipped with JWS 1.1 and is still in JWS 2.0 but deprecated) that use the SERVLET/SERVLET tags to embed servlet output into a page.

Matt,
Amazing, it works

Apparently IE5 has a bit of a browser caching bug.
If I have the following meta tag at the very bottom of my html it fixes my caching
problems. In the document I read it said that if the meta tag isnt at the very bottom
of the page then it doesnt work. After fooling around I tend to agree.
meta http-equiv="Expires" content="0" url="a description here"
/html
Also - the tag wont work if you include the other caching tags in your HTML.

it doesn't work either. Based on the docs for IE 5, this tag is ignored

Re: JSP and IIS?
Hi, We use JRUN, but I would use Resin over JRUN. It supports JSP 1.1, Servlet 2.2, which JRUN doesn't, and it allows it to be a standalone server so you dont even need IIS. Then again, I would also look at Tomcat, and Orion app server (www.orionserver.com) as replacements for IIS, which tends to have some problems we have noticed here. -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of zoxx Sent: Thursday, April 13, 2000 4:43 PM To: [EMAIL PROTECTED] Subject: JSP and IIS?

[RE]How do I use RMI in JSP
I think that it is security manager in RMI.
You have to setting up secutiry manager.
In case of application,
C:\java -Djava.security.policy=java.policy application name
### java.policy
grant {
permission java.security.AllPermission;
};
In case of applet, you don't warry. Because of that is already setting up security
policy.
but in jsp ...??? T.T
In case of JSP, I suggest modify java.policy file.
Edit C:\jdk1.2.2(jdk home directory)\jre\lib\security\java.policy
and then add permission java.security.AllPermission;
see in below
grant {
// Allows any thread to stop itself using the java.lang.Thread.stop()
