Can I combine ASP and JSP pages?

Hi all,
Maybe a dumb question...
but Can I have ASP pages in my JSP application?
My problem is as follows:
In the JSP pages of my application, I have some links to ASP application:
http://domain/app.asp
Now IIS is running on another port. But I do not want to go through all my JSP and change the above link to:
http://domain:port/app.asp
Instead any request to http://domain/app.asp should be automatically forwarded to http://domain:port/app.asp
How can this be done? I am using Tomcat as my JSP container.

Actually that is not what I am looking for. I dont want to 'buy' any product. I dont want to deploy ASP application with the JSP application. I just want to redirect the client to another website through an ASP page.
Only catch is that this ASP page needs to sit in my JSP container (Apache Tomcat). Is this possible?

How to combine servlet and jsp

I'm doing a project. My friend using jsp. and i using servlet..
we are confused, how to combine servlet and jsp. or we can just use redirect??
but it's still doesn't work properly...thanks for your helpp

You can use RequestDispatcher interface for calling a JSP from a Servlet, or vice-versa.
Following is the code for sending output to a JSP page from a servlet:
javax.servlet.RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(�/Ashu.jsp�);
request.setAttribute(�Name�,�Ashutosh�);
dispatcher.forward(request,response);
- Ashutosh

Urgent....How can i redirect to my jsp page from servlet in init() method..

How can i redirect to my jsp page from servlet in init() method..Becoz that servlet is calling while server startsup..so im writing some piece of code in init() method..after that i want to redirect to some jsp page ...is it possible?
using RequestDispatcher..its not possible..becoz
RequestDispatcher rd = sc.getRequestDispatcher("goto.jsp");
rd.foward(req,res);
Here the request and response are null objects..
So mi question can frame as how can i get request/response in servlet's init method()..

Hi guys

Ive just learned that i can use loadjava to load jsp pages into the database.

Ive just learned that i can use loadjava to load jsp pages into the database. How is that possible. How can someone go to my lets say, index.jsp page and actually see it if its inside the database? What authenticates it? Where would you set the parameters to tell http(apache) to look inside the db for the pages?
Any ideas?

Thanks for the reply. If I put the file on the database, does it have to be in a particular location? I've put it on the database server, launched sql*plus (as APPS) and ran the following:
execute dbms_java.loadjava('-v', 'ZebraGetPrinterFromXML.class');
PL/SQL procedure successfully completed.Then when I try to run a process that uses this I get this:
ORA-29540: class ZebraGetPrinterFromXML does not exist

Use two streams to manager client video/audio,Can i combine streams and record it with server AS API

Use two streams to manager client video/audio,Can i combine streams and record it with server AS API
I tried Stream.play()
var s=Stream.get("combine");
s.play("video");
s.play("audio",null,null,false);
s.record("append");
it's don't work!!

Thanks, that's what I had thought. Our domain.com zone is sourced internally and replicated to our advertisers for external users, so there's no way to change the result for internal vs external users.
This is a rudimentary question that I should already know but I sort of inherited this after it was built: Can I have users sign in with their email address ([email protected]) but under the hood, their SIP address is [email protected]? This would let users
sign in with an address they expect, but it would take advantage of the the local lyncdiscoverinternal record.
Thanks,
Matt

A single report can't combine portrait and landscape oriented pages

Post Author: joelo2
CA Forum: Crystal Reports
Hi,
Can a single report in Crystal report XI (version 11.5.8.826) combine portriat and landscape oriented pages like Crystal report 2008? For example, I have one main report with several subreports in the main report. I want one subreport be in portrait page orientation and the other subreports in landscape. Can I do something like that in Crystal report XI version? I even tried writing a small .net program to do this, but it doesn't seem to allow me to do that programmatically either. Please help

Post Author: ngra
CA Forum: Crystal Reports
I'd like to elevate this issue with Crystal Reports XI. There is a critical application which we developed in-house which needs both portrait and landscape orientation in each of the 30,000 plus documents we are sending out every month.If developers in Business Objects are picking this thread up - we need a patch for this limitation - quick. Right now, we are toying with the possibility of exporting the documents into a text format with markers indicating if a page is portrait or landscape. This is to be loaded into a Xerox machine (which costs hundreds of thousands of dollars), where it is mapped automatically to portrait or landscape. Note to Business Objects: This will provide us and countless others with much value. Think 80/20 rule - most bang for your development bucks and value for your customers!

ASP AND JSP

I am developing a facility that has to email up to 3 individuals at 1 user's request.the data that should be emailed is extracted from a sql database. as far as i know i can't program this using jsp but i know that it is possible with asp using sendmail, can i therefore, combine an asp page with jsp pages. can a jsp page be redirected to an asp page and vice versa - will tomcat handle this, do I need IIS configured for the ASP?????
First of all is this possible using just jsp.
For those that don't understand my question:
A user clicks a submit button after entering three email addresses. Records are extracted from the sql db and emailed in html format to the 3 email addresses. I don't want to do this manually - too much maintenance work....i want it programmed.

Can you open a second jsp page as popup/new window?

Hi all gurus!
I have a question regarding popups/new windows in an iview application. Instead of starting with a question let me instead describe what I want to do.
We have a jsp page that presents a search and then the search result in a table where one column is "clickable". When the user clicks a cell a server round trip retreives data specific for that cell value. This is standard functionality and already fixed so here is what differes: we want a new jsp window to open like a popup, with the data retreived from the server round trip and at the same time the first page with the table shall still be there so that you just can close the popup and click the next cell which creates a new server round trip and a new jsp popup and so on.
My solution which doesn't work yet: In application "a" I have a JavaScript for the clicked cell which opens another iview application "b" in a new window, by window.open("navurl_to_the_iview"), and that works fine.
At the same time the value of the clicked cell is written to the data bean and the bean is put in the http session (since component session does not reach between applications).
The second iview "b" retreives the bean from the http session and fills the jsp page with data.
Here is now the problem: no data is displayed and this because the iview "b" retreives the bean BEFORE iview "a" has been able to put the bean/value into the http session. How do I know this for sure? Simple, if I do a refresh of iview "b" the value is displayed.
I could do a JavaScript that recursively checks if the value in the bean is null or not but then I have to do a method that retreives the bean from the http session each time.
This could work but I wonder if this is the most simple solution. So my question for you gents and madams is: do you know of a more simple solution?
Best regards
Benny Lange
Edited by: Benny Lange on Oct 6, 2009 11:33 AM

Hi you all.
In this case the solution was to pass the id in the url to the second iview and let that iview use the id to retreive data from the backend system.
But I still think the question is interesting, if it's possible to open a second jsp window after a server round trip and still have the first one open.
All the best
Benny

Java File and JSP Page

To combine a multiple jsp pages in a one single page

hi all,
my problem statement is, i have 5 tabbed panes i,e each in a jsp page i need to put all those information into one single jsp page...while submiting the data. so how can i do about this using jsp.
regards
geetha

The use of frames is highly discouraged (as is the use of scriptlets). So don't even think about it.
You can just include a JSP page in each tab using jsp:include. You can hide/show the tabs using CSS/JS and/or a request parameter.

Pass Object Between Applet and JSP Page

Hi all,
How can I pass an Object(such as Vector, File), rather than just string to the Applet from a JSP page?
Thank you.

I used Base64Encoder and Base64Decoder from servlets.com utilities.
* convert any serializable object to a String
public synchronized static String objectToString(Serializable obj) throws Exception {
    ByteArrayOutputStream bos = new ByteArrayOutputStream(100);
    ObjectOutputStream oos = new ObjectOutputStream(bos);
    oos.writeObject(obj);
    byte[]bytes = bos.toByteArray();
    bos = new ByteArrayOutputStream(); //to save the encoded String
    Base64Encoder enc = new Base64Encoder(bos);
    enc.write(bytes);
    String encodedString = bos.toString();
    //close all
    enc.close();
    oos.close();
    bos.close();
    return encodedString;
* Recreates the object from the encoded String
public synchronized static Object stringToObject(String str) throws Exception {
    ByteArrayInputStream bis = new ByteArrayInputStream(str.getBytes());
    Base64Decoder dec = new Base64Decoder(bis);
    ObjectInputStream ois = new ObjectInputStream(dec);
    Object obj = (Object)ois.readObject();
    ois.close();
    dec.close();
    bis.close();
    return obj;
}

Can I combine ASP and JSP pages?
