You already got writer
i converted download servlet to jsp, and... exception occurred -"You
already got writer."
here is my jsp code..
%@ page errorPage="error.jsp" %
%
String file = request.getParameter("p_file");
byte b[] = new byte[1024];
File file=new File(pp_file);
FileInputStream fin=new FileInputStream(file);
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename=" +
pp_file + ";");
ServletOutputStream dataOut = response.getOutputStream(); // maybe, this
line caused problem.
int numRead = fin.read(b);
while (numRead != -1)
{
dataOut.write(b,0,numRead);
numRead=fin.read(b);
}
dataOut.close();
%
so i tried to use out instead dataOut ..like this..
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename=" +
pp_file + ";");
int numRead = fin.read(b);
while (numRead != -1)
{
out.write(b,0,numRead);
numRead=fin.read(b);
}
at this time, content of file just displayed on browser..
how can i solve these problems ? anybody knows ?

Re: JSWDK DOESN'T START
Ritesh, Your error message does look like a classpath problem, but there are a couple of other things you need to make sure you have done that aren't mentioned in the readme. You said you were a newbee and some of these things can shot a newbee in the foot. Anyway, they all shot me. I assume that you have read the readme, so that you started the JSWDK up with startserver or startserver.bat depending on whether you were on UNIX or Windows. If you are on a Windows machine and didn't get the "Out of Environment Space" error message, then the initial environment is OK. If not look at the read me and follow it's directions for MS-DOS window configuration. One of the things the readme assumes and doesn't mention is that you must be connected to the net for startserver or startserver.bat to work properly (the real point is that you need an IP address). You probably are since you didn't mention the error messages that you would have gotten. However, again assuming Windows, 95 and 98 do not automatically come net connected. NT may or may not, depending on how it's set up. Given that you are using JSWDK, which isn't something one would use in a commercial environment, you are probably connected to the net through your ISP, probably through a dial up. Anyway you need to connect somehow, especially if your IP address is dynamically assigned (because that's how you get your IP address). This is true even though you are only using "localhost" and theoretically aren't going anywhere outside your own machine. A net connection with the IP needs to be established when you do startserver or it doesn't know how to find localhost, because it doesn't know it's IP. Now assuming that you've gotten this far, one more shoot your self in the foot possibility which is assumed and isn't documented is that your browser must be configured to accept cookies. That is the default for both Internet Explorer and Netscape, but both allow you to "Disable all cookies", which you may have done. To allow cookies, in Netscape click on Preferences under the Edit pull down and then negotiate to the Advanced section. If you want to watch how cookies are used under the covers by JSWDK (and most servers for that matter) click on the radio button for "Warn me before accepting a cookie), otherwise click on the radio button for "Accept only cookies from the originating server". I don't have IE in front of me at the moment, but the process is similar (I think it uses Options instead of Preferences, but look around on the pull-downs and sub-menus and you should find it). Do NOT click on "Accept all cookies" for security reasons. hope this helps, Camille Ritesh Sinha wrote: Thanks for your replies. But i have checked class paths. The locations of the webserver.jar, tools.jar, rt.jat etc are correctly specified. I guess the problem is due to Initialization on the DefaultServlet as the command prompt window shows. The startup file is not able to initialize the DefaultServlet. So the problem still persists and i will be grateful for any further help.

Re: JAKARTA: which release to choose?
We "upgraded" to 3.1 from a pre-3.0 nightly build and experienced problems with sessions expiring almost immediately instead of expiring after the default of 30 minutes.

Hi everybody, currently we are using apache and jserv for linux, but to use the new Servlet/JSP-API we want to switch to Jakarta (which seems to be the only implementation of Servlet API2.2 and JSP 1.1) well, at the jakarta page there are three offerings: Tomcat 3.0 release (is said to be the most stable version) Tomcat 3.1 milestone (is said to be not very stable) (Tomcat 3.1 nightly build - all right, this one seems not to meet our needs..:) but the following quotation from the web-page http://jakarta.apache.org/news/news.html is confusing: "As compared to the 3.0 final release, this drop contains a significant number of fixes from a large number of contributors, as well as a few minor functional regressions which are a necessary part of some of the architectural restructuring underway." do the "significant number of fixes" outweight the "functional regressions" or not? Has anyone a hint? Who has experience with Tomcat 3 / 3.1? Or do there exist some linux ports supporting Servlet API 2.1+ / JSP 1.1 which we should consider? thanks a lot, Joe Peer --- [EMAIL PROTECTED] == = To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

GNUjsp
Hi, http://www.bestiary.com/moose/jsp/install.html Check this URL mentioned in the installation file of the GNUJsp.jar file. This is what I did for several hours before I was successful. 1. I put the jsp files in the apache root directory. 2. I specified a directory for the java files to be compiled into with the compiler.classpath option. "compiler.classpath" Not "classes" servlet.jsp.initArgs=compiler.classpath=c:\java ( I ensured that there are no spaces in this path ) 3. I set wrapper.bin=c:\jdk1.2.2\bin\java.exe ( for the interpreter) 4. I set wrapper.classpath=c:\jdk1.2.2\lib\tools.jar ( for the javac compiler) 5. I set the alias as in servlet.jsp.code=org.gjt.jsp.JSPServlet 6. I used this url to invoke the jsp. http://localhost/servlet/org.gjt.jsp.JSPServlet/snoop.jsp 7. It took some time to figure out that I can invoke the GNUJsp servlet like any other servlet with "snoop.jsp" I am still not sure if this helpful or not as I spent many hours doing this. There is a good article at www.servletcentral.com on working with GNUJsp . You have to search for it somehow as I don't remember the url. bye, Mohan === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Perhaps it's not showing up correctly in my email client. What I see is a scriptlet, not a comment: % Hello how are you" % If you wanted a hidden JSP comment, you would type: %-- Hello how are you" --% Scott Stirling West Newton, MA - Original Message - From: "Khurram Mahmood (OutlookLotus Notes)" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, February 14, 2000 2:16 AM Subject: JRUN idiosyncrasies! Hello, For some very odd reason, JRUN fails to display a jsp page if you have a double quote after a comment within your java code. For example: % file://Hello how are you" % the above line will confuse JRUN so much that you will get a message saying that the page can not be displayed. There is nothing wrong with the above line. It's another really annoying bug in JRUN. It took me several hours to find it. Who would think that a proper comment can screw up JRUN.

Re: SQL Server driver
There is a new PooledConnection interfaced added in JDBC 2.0 API. However, one must use a DataSource object rather than the DriverManager class to get a connection.

Re: JSP Architectural Question
Craig,
What would you do if the page in question could be viewed by anybody,
logged in or not, but certain parts of the display need to be hidden for
those who are not logged in (full functionality not available to guest
users, only to registered users). Would you wrap this if-else statement
around every single piece of the conditionally displaying code?

Great inputs by Mr. McClanahan and other in this thread.
In our application we have one servlet for each form and in addition to
the
action class with validated parameters, it validates the session. For ex.
to
access his account, the user should have logged in first(which is stored
in
the session). This is different for each form.
Where and how do think we can do, if we follow your model for one
controller
servlet?
What I do is build in a check in the doGet/doPost methods of the controller
servlet, and check for the existence of a particular object in the user's
session that is only put there by a successful login. This object is
removed
when the user executes your logout function, and is essentially removed by
a
session timeout (since it won't be there the next time the user makes a
request
-- they'll have just started a new sessiion) Then, the pseudo-code of
processing a request would be something like this:
Check for existence of the login-succeeded object
if (login object is there) {
Call the action class being requested
} else {
Display the login page
}
You'd need a special check that allowed the "process login" action to be
processed even if the user wasn't logged on.
In the "process login" action, after you are satisfied the user has been
authenticated, you add the appropriate login object to the user's session).
When they execute your logout function, just remove this object and
invalidate
the session.
I am a newbie to architecture, so hope you dont mind if this is a up to
the
par question.
Thanks,

Re: Sessions and IE 4.01
Is this true of all browsers? I've observed within Netscape that the session remains until either session.invalidate() is called or the session expires. Comments? Chris As has been discussed before, new windows in all versions of Netscape keep the same session. IE is a different story - both IE 4 and 5 have a browser setting (in Preferences or Internet Options) along the lines of "launch new window in a separate process". The default setting for these browsers should be OFF. If it happens to be set to ON, however, the new window will not keep the old session. I would advise against spawning new browser windows in general, for the following reasons: 1. They are confusing for the user, at best. Most users I've seen don't understand the concept of a "new browser window", and hence can't find a way back to where they started. They become completely lost, and this is known as a major Web site no-no. 2. Even for users who do understand the concept, the session issue that we are discussing is still grounds for a user's confusion. In other words, if a new browser window opens, does that mean that I'm "logged in" in the new window but not the old, or vice versa, or both? Just because keeping the same session across browser windows makes sense for us developers doesn't necessarily means that it makes sense to users. 3. They are annoying. The real problem is that users may not know to hit the little "x" in the upper right to close it. Once you open a new window on the user's desktop, it will stay there forever... There are cases where they MIGHT be useful. These are up for debate, as far as I am concerned: 1. External links - a lot of sites do this to prevent users from leaving their site. 2. A page that is much better for printing. For instance, a page with printable maps and directions, or Web-based reports that the users need to print. Eric M.

Servlet/JSP problems with WL 4.51
Hi all
I have a set of Servlets and JSPs running on NewAtlanta's ServletExec
servlet engine. I am currently porting them to WebLogic. I am facing a
few problems. I do not want to change any of my HTML/JSP/Java files
immediately. I want the same files to work in WL as it is. Pl help.
1. The servlets in ServletExec used to be invoked as
http://host/servlet/servletName. But in weblogic they are invoked
as http://host/servletName. I tried registering the servlet names
in weblogic.properties as
weblogic.httpd.register.servlet/XServlet=com.foo.XServlet
weblogic.httpd.initArgs.servlet/XServlet=param=value
Now I can call this servlet as http://host/servlet/XServlet and so
I dont have to change any html/JSP files. Will this cause any
problems in the future?
2. Since we used to run ServletExec on IIS, we created a virtual
directory called /jsp in IIS under which we had all the html and
JSP files. Our servlets will get the http requests, get data from
database, put the results in session/request variables and dispatch
it to appropriate JSP page. So, all our servlet code looks like
this:
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("/jsp/test.jsp");
dispatcher.forward(request, response);
How do I make this code work with WebLogic? Is there any way to
create virtual directory and make it work like in IIS?
Thanks for any help.

RI vs spec (was tomcat-as-a-reference implementation
Hi Craig, VInce, and everybody else: The specification is the ultimate arbitrer. The spec can be used by vendors (platform and tools), documentation authors (books, etc), and end-users. Watchdog are compatibility tests. They can be used by anybody, including implementors. If the RI (tomcat) violates the spec, it is a bug and it should be fixed. It is harder with features that are outside of the spec. Neither the Servlet 2.2 nor JSP 1.1 are without holes and any RI, regardless of how it is implemented or distributed, has to make some decisions. Maybe we should document them somewhere to address this problem. Let's talk. Both Danny and I are working on an errata for Servlet 2.2 and JSP 1.1. And we hope to close more holes and complete key functionality as part of Servlet.next and JSP.next; I hope you will help us with that.

Yes, I'm concerned about this from the perspective of the vendor of a servlet/JSP engine that strives to faithfully implement the specs. My concern is that people will apply the following logic to non-spec features: 1. Tomcat is the Reference Implementation of servlets/JSP. 2. Tomcat implements Feature X. 3. Vendor Y's servlet engine doesn't implement Feature X, or implements it differently than Tomcat. 4. Therefore, Vendor Y's servlet engine isn't spec-compliant. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Tomcat-as-a-reference implementation?
"Scott Ferguson" [EMAIL PROTECTED] wrote: Ted Neward wrote: Does anybody else have a problem with a "production-quality" servlet engine also serving as the reference implementation for servlets and/or JSP? I have always operated under the belief that a "reference implementation" was supposed to be plain-vanilla, no optimizations, stick-to-the-letter-of-the-spec, if-it-ain't-in-the-spec-it-ain't-in-here kind of implementation. JSWDK was precisely this--it demonstrated servlets simply, cleanly (IMHO), without a lot of bells-n-whistles to get in the way. My concern is that Sun's stated intent (by calling it a reference implementation) is at cross-purposes with Apache's stated intent (to make it a production-quality engine). These are, for the most part, mutually-exclusive goals. vendor-bias Tomcat isn't really a reference implementation. It's the Apache group's servlet implementation. Sun has chosen, for its own reasons, to select the Apache group as its preferred servlet vendor. Calling Tomcat a "reference implementation" is just marketing fluff. Orion is a better reference implementation than Tomcat in the sense of "if my implementation doesn't do the same thing, then it's probably wrong." Orion implements the specs more faithfully than Tomcat does. Unfortunately, this diminishes Sun's credibility as an impartial standards arbiter, but that's Sun's choice. Microsoft doesn't even pretend to be impartial with its ASP standard, and it's rather successful, so maybe it's not a bad decision. /vendor-bias I think it's important to distinguish between the political and technical here I don't think theres any doubt that endorsing tomcat as a reference implemention was at least a partially politically motivated decision - hence the "marketing fluff" However, from a techinical perpective, I believe that tomcat can/will function as a good reference implementation. The reasons for this are: 1) tomcat comes with watchdog, the compatibility tests :-) 2) sun originally donated tomcat to apache, and many sun people are still working on it 3) tomcat is/will be very configurable and thus most if not all of the bells and whistles which ted found so disturbing are optional, unlike other vendors implementations where (presumably) the bells and whistles are mandatory. Thus, a minimal configuration of tomcat would have exactly the feature set you'd want for a RI. Of course, the current tomcat isn't there yet, but tomcat.next will hopefully fit the bill.
