JFileChooser support in JSP

Hi, just a quick question about using JFileChooser in JSP. Basically I'm totally new to JSP being a Swing developer, however I've been asked to scope and estimate a block of work where the frontend is going to be in JSP. Part of the functionality requires the usage of the file chooser, so what I was wondering is if the functionality and usage of JFileChooser would be the same in JSP as it would in Swing or different or not it at all?
Any comments welcomed :-)
Thanks
Damo

No, support for the JFileChooser from JSP... *
reasons:
1) JSP runs on the server, and is done before the user ever sees the page, so the JFileChooser could not be opened via a user action
2) The JVM being used is on the server, not the client machine. That means that the File being looked for would be on the Server, not the client machine.
3) The JVM being used is on the server, not the client machine. That means that the graphics environment that is being used is the server's graphics environment. the JFileChooser (or any swing component) would be drawn on the server's screen, not the client's. The server may not even have a screen, or a GUI.
*technically, you can create a JFileChooser, but the user would never see it, unless the user happened to be on the server machine.
Alternatives might be to use the Apache Commons FileUpload component with the HTML component <input type="file".../>. Or to make an Applet that does the job.

Multilanguage support in jsp reports (web layout) and in jsp general

Hi!
We have to develop multilingual applications, so we decide to use Oracle TranslationHub for translate our reports. This is restricted to paper layout at the moment.
1.
Are there plans to support jsp reports layouts through TranslationHub?
2.
I have played around whith some reports jsp tags (rw:), but it seems that it cannot reference boilerplates. If I could read the value from a paper layout boilerplate this would be a temporary solution, as all of our actual jsp reports contains paper layout as well and this I can translate with Oracle TranslationHub.
3.
Do you know any standard implementation for multilanguage support for jsp like resource files? Any hint to ducumentation would be helpful.
With kind regards
Torsten

Support for JSP's located in WEB-INF directory

Several application servers support the use of placing JSP pages underneath the WEB-INF directory, to insure that only server side workflow forwards requests to those pages and not direct URL access. IN addition the JSTL specification supports the use of
<c:import url="/WEBINF/published/campaign_Arts.jsp" />
Does OC4J 9.0.3 support this syntax? I cannot get it to work. Is there an application configuration file I need to update to support this?
Thanks

          thank you for your reply...
          but...
          My problem is that i want to serve jsp pages that include various other jsp pages.
          But i don't want those other pages to be served directly. The approach of putting
          the jsp files in the WEB-INF, or in a sub directory of it, worked fine on Tomcat.
          The way i look at it is that the server has direct access to them when putting
          togetter the main jsp, but they can't be accessed from the outside. But this seems
          not to be the case.
          Any ideas?

Support of JSP in Oracle 8i

Dear all friends,
now I am using Sun Java Web server for serving my JSP's but I have heared that Oracle 8i support JSP .Could you please inform me that whether Oracle 8.1.5. has webserver itself and if it does ,does it support JSP.
any suggestion would be appreciated
Amirali

Oracle 8.1.7 (due this summer)will indeed have a web server in the database for running servlets and JSPs. Oracle 8.1.5 and 8.1.6 do not have this.

WebLogic 8.1 support for JSP includes using XML formatting

Hi,
          I have a web application I'm trying to deploy to WebLogic 8.1 which uses JSP includes.
          My JSP page starts with :
          < ?xml version="1.0"?>
          At runtime, I get this exception:
          java.io.IOException: javax.servlet.jsp.JspException: The taglib validator rejected the page:
          "org.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed., "
          Are XML formatted JSP includes supported ?
          Thank you
          John

I got a similar exception which was:
          java.io.IOException: javax.servlet.jsp.JspException: The taglib validator rejected the page: "org.xml.sax.SAXParseException: Attribute "xmlns:html" was already specified for element "jsp:root"., "
          This is how I fixed it:
          The taglib for the html was declared twice. Once in the main.jsp and once in taglibs.jsp. The taglibs.jsp was included in main.jsp (The jsp which was throwing exception)
          Hope this works for your case.
          Thanks

Greek support for jsp

Hello,
I am working on an MVC model where the user submits a form where the text is in greek, passes it to a bean and that is being read by a jsp page. Even though in the eclipse console the greek characters are apperaing in the jsp page where I am using this syntax
<jsp:getProperty name="upBean" property = "articleTitle" />
the text appears in question marks. Even though I have set the character encoding to greek
<%@ page contentType="text/html; charset=iso-8859-7" language="java" import="java.sql.*" errorPage="" %>
and even though I have set both request and response to
req.setCharacterEncoding("UTF-8");
res.setCharacterEncoding("UTF-8");
Any idea why is this happening and how to fix it would be more than appreciated
Thank you

public void doPost (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
req.setCharacterEncoding("charset=iso-8859-7");
this is how I did it but it gives me a
java.io.UnsupportedEncodingException: charset=iso-8859-7
and if I use utf-8 the whole page gets messed up including tha static content
any ideas?
Thanks for your interest

JSP 2.0 support in JDeveloper?

Hi,
Does JDeveloper 10g support the JSP 2.0 spec.? If no, why are there JSP 2.0 tutorials here,
http://otn.oracle.com/sample_code/tech/java/codesnippet/jsps/simpletag/how-to-simpletaghandler.html#run
that are deployed to the OC4J server? Is the embedded OC4J server of JDeveloper substantially different to the production OC4J? Can anybody help please?

JDeveloper 10g (9.0.5) supports J2EE 1.3 - so no JSP 2.0 support yet.
OC4J has a preview version with J2EE 1.4 support. It's still not production though.
Check it out at:

Browser that supports JSP

Does the Personal Web Server 4.0 support code jsp?
if the answer is no, then what browser does support it?
Please tell me, as soon as possible

PWS 4.0 is a web server, not a browser. All browsers support jsp since the web server will run the jsp page and generate html for the browser to view. You can look at a product called JRun to see if it provides an ISAPI extension for running servlets & JSP pages. If it supports this, you can JSP pages on PWS.

With the java software api's being in a constant state of evolution, each new
release of Jdeveloper adds support for the "then current" version of the java
software api's, if it does not already have it implemented.

IAS
IAS is Oracle's next evolution of the web server and application server
product technology superceeding the Web Application Server (WAS) and Oracle
Application Server (OAS) product lines.
IAS SERVLET API JSP API EJB API EJE VERSION
VERSION VERSION VERSION VERSION SUPPORTED
9I(1.0.2) 2.2 1.1 1.1 817
8i(1.0.1-NT) 2.0 1.0 1.0 816
8i(1.0.0-UNIX) 2.0 1.0 1.0 816
The IAS product contains two Java Virtual Machines (JVM) within it's
architecture.
They are called :
1) APACHE JSERV servlet engine
2) ORACLE ENTERPRISE JAVA ENGINE (EJE)
APACHE JSERV servlet engine
The APACHE JSERV servlet engine is an EXISTING product licensed from the
apache group which supports the servlet api 2.0.ONLY.
The APACHE JSERV product does not support ANY JSP's unless the customer
installs a third party jsp engine.
The IAS 8i/9i which has the APACHE JSERV product embedded in it, comes with
Oracle's JSP engine (OJSP) already integrated into it. OJSP supports JSP's up
to the specific JSP engine version documented in the Oracle Universal
Installer (OUI) for the 8.1.7 RDBMS or the IAS products. It is also documented
in the product's release notes.
Oracle ENTERPRISE JAVA ENGINE (EJE)
The EJE formerly known as :
1) Oracle 8i Java Virtual Machine (JVM)
2) JSERVER component,
3) Aurora JVM
was originally releas ed in the RDBMS 8.1.5 database with jdk 1.1.6 based java
support.
The currently supported versions of the Oracle 8i RDBMS, versions 2 and 3,
also known as Version 8.1.6 and 8.1.7, respectively, provides a jdk 1.2.1
based java virtual machine support.
"EJE" Version 816
This EJE, found in rdbms 8.1.6 and IAS 8i, contains support for the ejb
api 1.0, corba, and java stored procedures.
"EJE" Version 817
This EJE, found in rdbms 8.1.7 and IAS 9i, contains support for the ejb,
corba, and java stored procedures as well as the Oracle Servlet Engine (OSE)
which provides support for the servlets 2.2 api and JSP 1.1 api.
Note :
EJB support in the "EJE" Version 817 has been upgraded to comply with the EJB
1.1 api specification which includes "entity beans" support.
What is the bottom line ??
1) Servlets deployed to the APACHE JSERV must comply with servlet api 2.0.
2) Servlets 2.1 or higher are only supported in EJE's OSE component found in
the rdbms 817 or ias 9i products. Servlets api 2.0 can also run in the OSE.

which jvm is used by jserv ?? EJE or a separate jdk ?
The Jserv servlet engine is running in a separate jdk JVM external to the EJE jvm which is embedded within the "database" component of ias and the RDBMS.
See the reference below for more details ...
if jserv only support old apis, why it is in oracle's products ?
i would assume that the oracle servlet engine was under development when ias 8i was released and became available in time for the ias 9i and rdbms 817 products.
looking back in history leads me to believe ias 8i was a migration path to get to ias 9i or rdbms 817.
Based upon the long history of new releases of every oracle product being upgraded with new features, it's reasonable to assume that these products will continue to evolve.
when I deploy a jsp how to deploy in the right servlet container ("EJE") ?
as documented in the reference below, you can deploy JSP's to either the apache jserv jvm or the EJE since the ORACLE JSP engine functionality is in both jvm's.
there are many posts where you can see that people have deploy in jserv and they have problems because they don't use the right container (servlet 2.0 instead of
servlet 2.2) http://technet.oracle.com:89/ubb/Forum2/HTML/006349.html
when ias 8i came out this was clearly an issue since servlet support was at api 2.0, and the current servlet api was probably at 2.1.
oracle clearly made every effort to get ias 9i released quickly to supply a servlet 2.1 and 2.2 capable engine to resolve this issue.
since ias 9i and rdbms 8.1.7 are available this is no longer an issue.
The reference below explains the architecture and understanding it would eliminate a lot of "deploy to the wrong ias 9i component" issues.
so why jserv is bundled with oracle 8i/9ias since EJE support the right api version ?
if in ias 9i release , oracle had removed the jserv component without any advance warning, many customers would have been very upset since oracle makes every attempt to give advance notice before removal of functionality.

How to print break line in jsp.

in jsp where a bean.getProperty() value has a broken line. but it displays as a single line in the web page. when printing the line by System.out.println() statement, it displays as a verious new line where '\0' is applied but in jspbean.getProperty it does not.
For example :
It displays by SOP()statement as
Successful
No error
No restarts
No marked completed
but in web page it displays as
Successful No error No restarts No marked completed.
please provide the code that support in jsp file so that the output statement should like as SOP()statement output type.
Thanks in advance.

I guess you want to display CRLF (\r\n) in JSP?
Line breaks in HTML are generally represented as < br >.
You have 3 options:
1) replace CRLF by < br >.
2) style the line using CSS with 'white-space' set to 'pre'.
3) surround the line with the HTML < pre > tag.

Hi Raul
A better option would be to switch to Reports 9i because it natively supports Reports JSP tags. Your JSP then becomes seamless. And much more...
With 6i, you can look at using Reports Servlet.
