Converting jsp to OA Extension

Hello, everyone.
I have created 3 jsp pages that call some PL/SQL packages. These packages calculate estimates for Social Security, 401k savings, and Pension allowance at a user-entered retirement date, mainly using "get" and "set" procedures and functions. The displays are quite simple; I put most of my effort in getting the calculations right in the PL/SQL packages. Even so, I find it to be quite powerful in running various "what-if" scenarios, varying such things as 401k contribution percent, etc.
My task now is to implement this system as an extension to Self-service (probably with considerable consulting help). I am wondering what the appropriate structure is to use. What I envision is some global fields at the top to set retirement age, projected yearly wage increase %, etc, with tabs for Social Security, 401k, and Pension, with maybe a 4th tab showing totals, graphs, etc.
Does anyone have any ideas on sample code, tutorials, etc that might get me started? In particular, I can't see where the calls to the PL/SQL packages will go. In the Application Module?
Thanks for any suggestions or comments. My skills in OA Extension don't go much beyond the "Hello World" lab, so feel free to spell out any complexities.

Your page layout design should be according to the business requirement, as for the technical design, you need to call your PL/Sql objects from EOImpl, that is the correct place for business logic.
Thanks

I download itext for convert jsp to PDF. How to set content type for PDF.

I download itext for convert jsp to PDF. How to set content type for PDF. I try
<%@ page contentType = "application/pdf;charset=TIS-620" %>
, but the page does not PDF.
Thank.

PDF files are usually binary files, JSPs are not well-suited for binary content.
(If you download the result of your JSP you'll see that it is not a valid PDF file; it will have probably a lot of whitespace and linefeeds, that will choke your PDF reader.). The first few characters must be
"%PDF-" without whitespace.
You can try using PDF files encoded as text - check if you can use text-encoded PDFs in iText.
Try using a Servlet instead.

Converting Jsp file to Java file-Urgent

hi,
Is it possible to convert Jsp file to a Java file?

Hi
Put all the logic u have put in the JSP, into a servlet and compile it.
Your webserver also does almost the same thing, it take the JSP and converts it into a servlet.

If JSP is an extension to Servlets then in what case is one better than the other... can someone give me an example?

i wouldn't want to argue with previous poster, because i'm not too over confident with this thing, but i have got an undersatanding that .jsp's are translated to servlates and then compiled...
so technicaly jsp does exactly what servlet does...
but when you work with .jsp pages, then you can create web applications more rapitly and indeed there are those special tags that you may define for your self... (though i've never used them -- but then again, i'm just a n00b to JSP technology)

Where can i see the java file of a container converted JSP file

I am using weblogic11g.
Where can i see the java file of a container converted JSP file .

Hello.
If you look for .class files, you will find them under $domain/servers/serverName/tmp/application/etc.
If you look after .java translated files, nowhere if you don't have "keepgenerated" param set to true in the appc/jspc command line (may be set in a web descriptor but can't find a reference). The foo.java will be find in .\WEB-INF\classes\jspservlet.

Which part of container actually converts jsp to servlet

hi all,
although it's container's responsibility to convert
jsp to servlet, but can any body tell me
which part of that container is actually
is responsible for this conversion
thanx

At least for Tomcat, the engine that converts a JSP into Java code is Jasper. Then the container has to take the Java code and compile that to a .class file. Once it has that, it keeps reusing the .class file whenever you make a JSP call.
That's why first page access is often slow.
A way to speed it up is to pre-compile your JSPs.

Converting JSP to servlet

Hi,
Can anyone show me how to convert my jsp to servlet. Then, from servlet to classes. Thanks.
cheers,

well, jsp pages are converted at run-time to servlets, e.g. if you are using tomcat as jsp engine, you will find the servlet java files somewhere under $TOMCAT_HOME/work/localhost. you can compile these java files to class files.
PS: There is a forum in here for JSP, and I would recommend that you post your questions there in the JSP forum (this one is about databases)

HTML to PDF with Java, using OpenOffice.org - example here: [http://www.dancrintea.ro/html-to-pdf/|http://www.dancrintea.ro/html-to-pdf/]
You can use OpenOffice.org, running as a server and command it remotely for document convertion.
Besides HTML to PDF, there are also possible other convertions:
doc --> pdf, html, txt, rtf
xls --> pdf, html, csv
ppt --> pdf, swf
Code example:
import officetools.OfficeFile; // this is my tools package
FileInputStream fis = new FileInputStream(new File("c:/test.html"));
FileOutputStream fos = new FileOutputStream(new File("c:/test.pdf"));
// suppose OpenOffice.org runs on localhost, port 8100
OfficeFile f = new OfficeFile(fis,"localhost","8100", true);
f.convert(fos,"pdf");

Convert jsp page into xml or dom for search

Hello everyone,
I have to build an application that searches for message beans in all jsp page. I did it the traditional way, using scanner and string methods. Its working but its not perfect. So i want to convert all my jsp page into xml format and then process them. My jsp pages are quite complicated. I used some jars that convert them into jspx . But its not working. Please help
Thanks in advance

Well its like this.I need to develop a program that reads all the message bean keys.. We have lots of struts webapps. All messages in the jsp pages have been externalised and internationalised. Now i have to build a program that given a webapp path prints out all the message bean keys used in the webapp. I have developed the program using the Plexus Directory scanner to filter all the jsp pages and java util Scanner to read line by line and used String functions to search for keys.
Now thats not the best soultion. The best way, imo, is to cinvert the jsp into xml pages and then we can parse the xml pages easily. The' problem is to find a way to convert the jsp pages(jstl +javascript) into xml.
Can you help me out?
Thanks

Convert files with WMV extension to QuickTime

Is there a ways to convert video files with wmv extension to quicktime on the ipohne it self, so the video can be played on the iphone?

No. There are apps that will convert unprotected WMV files on a computer to something that the iPhone can play. Google is your friend to find video conversion software.

Converting JSP to PDF

Hi All,
I have a JSP file and I want to convert it into a PDF and save it in a specified directory.
Can anybody suggest what should Ido ..??
Any help would be appreciated.
Thanks a lot in advance.

no. This has nothing to do with Java anyway. Nor does it matter whether it's JSP or ASP or php or whatever.
Of course you could use a servlet instead of a JSP and have that render the data as a PDF, sending the PDF to the browser as a binary stream when ready.
That's the preferred way, as it allows you full control. It does of course require you to know how to use a PDF generation library to format the output correctly, and the servlet library to send binary data.

Converting JSP to JSF

Hi,
I am new to JSF.
Could someone suggest how to convert existing JSP project to JSF and Tiles ?
TIA,
Oleg.

Yes, we do have to convert.
We wrote a pilot of project using JSP [with some YUI and JQuery widgets]
and then learned that client wants JSF (have a bunch of other JSF projects),
so now I have a week or so to convert it. [I personally would use Flex for the GUI] ;-)
Is there a way to wrap up JSP into JSF ?
I guess, we also need to move some HTML/JSP widgets into JSF components.
Please advise,
Oleg.

Convert JSP to Word with print-layout

Hi:
I have a task of openning a JSP file in word format.
So far I am able to open the JSP in word format by
setting
response.setContentType("application/vnd.ms-word");
This setting opens-up the JSP file in MS-Word correctly
but the View option in Word gets defaulted to "web-view"
where as my requirement is to get this in View in "print-layout"
option.
Another issue:
Word has a concept of Headers and Footer which are printed
automatically after every page break during printing
Question: how to incorporate such headers and and footers in the
original JSP document so that when it is converted to
Word they (header/footer) prints during printing.
Thank you,
Farooq Chishty

I think, that what you need to do, is to use some api that actually generetes binary code that then is understood by MSWord as a word document.
What you are doing now is to tell word to open an html document.
There are some apis that allow to do what you want, buy I insist you must generate the doc object and then print the binary chunk to the browser.
If this is what you neen, let me know y can point some web sites.
Hope it helps

Convert JSP to valid XML

Does anyone know a good (preferrably free) tool to convert a JSP file to valid XML format?
I've tried Tidy, but this tool can convert HTML to XML or XHTML but not JSP to XML. It will check first
if my JSP file is valid HTML, which it is not (because there are a lot of JSP tags included, which will
result in valid HTML, but which are not initially).

I have not heard of a tool converting a JSP file to a valid XSL file. I remember ourselves manually converting a Cold Fusion site to an xsl format with reference to a xml files.. men, very tedious even with an XML Spy on the help and a tool that automatically creates a labels.xml to store all labels and images and access them via the <xsl:value-of> tag.
if you can't find a tool that converts a jsp file to an xsl/xml file maybe you can remove all those scriplets and covert a pure html file out of it. or better yet, when a JSP file has been processed, it returns a pure HTML file, right? so you can get that pure HTML source code and convert that to xsl/xml using the tool you have then insert the scriplets and other Jsp tags after the convertion.
I think that would be a lot easier in absence of a tool. rather than going through the saving of all your labels in an xml file and go through all that <xsl:value-of> tags to access your labels.
by the way, can i know where i can find that tool that converts an HTML file to an xsl/xml file.
