File saven jsp

i am writing data got from database to csv file in jsp , but i want to give option for user to give a file name so can anyone help me is there a tag in html or jsp where i can give user option to save a file just like html input file type tag .

Well, you can embedded this code to hint the browser to use the file name when saving the CSV output. Or, you can write an applet or use JNLP if you really want the "Save As..." functionality.
<%@page contentType="text/csv" pageEncoding="UTF-8"%>
<%response.setHeader("Content-Disposition", "filename=xyz.csv");%>I sort of disagree with purists that that JSP can't be used to generate CSV. It is no different than generating HTML output from the database.

How to import a jar file in JSP

How to import a Jar file in JSP Page.
please reply its very urgent!

Hey I am facing a similar problem:
I have this jar file lbswebservice.jar that I have to use for my application.
I added it to the classpath, I copied it in my WEB-INF/lib folder, but when I try to access classes in this package, it doesnt work.
For example the jar contains the package com.blipsystems.lbs.ws.messages.* ; that contains different classes, like the Campaign class.
I tried to use this class (just to create an object) in different context (through jsp, or just through java test classes), but it never works, i get the error: com.blipsystems.lbs.ws.messages.Campaign cannot be resolved to a type
I am a bit desperate here...

How to access variables declared in java class file from jsp

i have a java package which reads values from property file. i have imported the package.classname in jsp file and also i have created an object for the class file like
classname object=new classname();
now iam able to access only the methods defined in the class but not the variables. i have defined connection properties in class file.
in jsp i need to use
statement=con.createstatement(); but it shows variable not declared.
con is declared in java class file.
how to access the variables?
thanks

here is the code
* testbean.java
* Created on October 31, 2006, 12:14 PM
package property;
import java.beans.*;
import java.io.Serializable;
public class testbean extends Object implements Serializable {
public String sampleProperty="test2";
public String getSampleProperty() {
return sampleProperty;
}jsp file
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ page import="java.sql.*,java.util.*"%>
<html>
<head>
<title>Schedule Details</title>
</head>
<jsp:useBean id="ConProp" class="property.testbean"/>
<body>
Messge is : <jsp:getProperty name="msg" property="sampleProperty"/>
<%
out.println(ConProp.sampleProperty);
%>
</body>
</html>out.println(ConProp.sampleProperty) prints null value.
is this the right procedure to access bean variables
thanks

Deploying a WAR file containing .jsp and servlets (also uses JNI)

Deploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit     /jakarta     c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy      -u /jakarta
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\jakarta-examples
          C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Restart the web server (I don't think you have to restart, but .. might as well).
2)Deploy your web-application
My Foo.war has the following structure.
You can use jar tf Foo.war to look at the file contents from command line (assuming you have JDK installed and the bin is
in your PATH)
Foo.war
- [META-INF]
- [WEB-INF]
- web.xml
- [classes]
- Bar.class
- MoServlet.class
- [lib]
- ThirdParty.jar
- [natlib]
- extlib.dll
- foo.jsp
Here is our application scenario:
foo.jsp uses a class call Bar (it is not in any package). The Bar java class uses classes from ThirdParty.jar. The
ThirdParty.jar in turn uses JNI to load library extlib.dll. foo.jsp also calls /servlet/Mo as well.
Now to deploy it, do the following:
(a) Make sure that within foo.jsp, you import the Bar class ( I don't know why you have to do it, but if you don't you get
JSP compile error).
<%@page language="java" import="Bar" contentType="text/html"%>
(b) Check web.xml (for Servlets)
Within web.xml, make sure you have the following mappings:
<servlet>
<servlet-name> MoLink </servlet-name>
<servlet-class> MoServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> MoLink </servlet-name>
<url-pattern> /servlet/Mo </url-pattern>
</servlet-mapping>
(c) Deploy the application
Using command line:
wdeploy deploy      -u /foo
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\foo-dir
          Foo.war
(d) Change web-apps.xml file (for picking up ThirdParty.jar)
It is located in
C:\iPlanet\Servers\https-yourserver\config
You should see something similar to following after successful deployment.
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true"/>
Change it to look like following to pick up the ThirdParty.jar
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true">
<class-loader reload-interval="300"
          classpath="C:/iPlanet/examples/foo-dir/WEB-INF/lib/ThirdParty.jar"
          delegate="false"/>
</web-app>
(e) Change jvm12.conf file (for JNI)
It is located in
C:\iPlanet\Servers\https-yourserver\config
Add or uncomment the following lines:
#optional - just helps with instrumenting the jsp and servlet code
jvm.include.CLASSPATH=1
jvm.enableDebug=1
nes.jsp.enabledebug=1
jvm.trace=7
jvm.verboseMode=1
#required for JNI
java.compiler=NONE
jvm.classpath=.;C:\JDK1.3.1\lib\tools.jar;C:/iPlanet/Servers/plugins/servlets/examples/legacy/beans.10/SDKBeans10.jar;
jvm.option=-Xrs
jvm.option=-Xnoagent
# not sure if this is needed for iPlanet web server
jvm.option=-Djava.library.path=C:/iPlanet/examples/foo-dir/natlib/ -Djava.compiler=NONE
(f) Change magnus.conf file (for JNI)
We HAD to change this file in order for ThirdParty.jar file to pick up the native C++ code using JNI. Apparently, the
iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.

Uploading a file using jsp and com.oreilly.servlet lib package

Sorry to bother you but I need your help folks
I am developing an application to pick up files from a database and sent to a specified location on a different system.
I am presently trying to run this code,I have placed this lib package from oreilly which is supposed to encapsulate the usage of file uploads,which is a jar file called cos.jar into C:\Program Files\Java\jdk1.5.0_03\jre\lib\ext folder .I have a jsp page that calls the bean which does the upload and implement the classes in the oreilly package.I am using tomcat 5
[b]the jsp page that acts as the user interface
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

Hi,
Looks like you are missing a file from the classpath. Make sure servlet.jar is available in your classpath. Ordinarily files in <tomcat_home>/lib directory should be added automatically. You need to check why it hasn't been added in your case. A good place to start would be the bat files in the bin directory viz startup.bat, catalina.bat etc.
cheers,

I have successfully used Multipart classes from Oreilly. I believe that's the same one you are referring to. I have implemented my Upload using a servlet though. If you can post what exactly is your trouble using that code, I will be glad to help you with it.

                        out.print("file not exist");


What does the file existing or not really have to do with it?
You can try it like this:
String pg=request.getParameter("page");
        if( pg!= null && ! "".equals(pg)){
                String webPath = pg + " .jsp";
                String realPath = request.getRealPath(webPath);
                File f=new File(realPath);
                if(f.exists()){
                        out.print("file exist");
                        %>
                        <jsp:include page="<%= webPath %>" />
        <%
                }else{
                        out.print("file not exist");
        }Alternatively you could try using a request dispatcher:
RequestDispatcher rd = request.getRequestDispatcher(webPath);
if (rd == null){
// doesn't exist
}

Display uploaded file on JSP page

Hi All,
I want to display uploaded file in JSP.
Initially I am displaying File Name after saving the file & click on edit link.
i.e on JSP Page I have File Upload component & save button.With that save button I am saving my file to databse.
So when I click on edit link I am getting that file name from Databse then I am displaying it.
But now I want to display uploaded file name on JSP page before saving to databse.i.e I will have browse & Upload button.When I click on browse button I will open window from where I will select file.
This is working fine as,<x:inputFileUpload id="uploadfile" value="#{errorLotBean.file}" storage="file"></x:inputFileUpload>
But when I click on upload button that uploaded file should be displyed there only.Can anyone please tell me how to do this ?
Thanks
Sandip

Problem loading resources file in JSP using f:loadBundle

Hi,
We are facing problem while loading our properties file in JSP using f:loadBundle.we tried the following way
<f:loadBundle basename="resources.ApplicationResource" var="msg"/>
This properties file is src java folder and also in WEB-INF-->classes->resources folder
but even then its not able to load.I made an entry in the faces-config for message-bundle. But of no use.
Any pointers would be of great help.

does your file calls
ApplicationResource.properties ?
If so is it in
the package resources ?

How to display a pdf file in jsp

hi,
How to display a pdf file in jsp iam having a class which will return fileinputstream of the file object. the pdf file is in server.
regards
Arul

A JSP is a combo of HTML and Java, so you can't really "display" a PDF file in a JSP.
You can provider a href link to the PDF file in your JSP.
You can use some utility package to read the contents of the PDF, pull certain things out of it, and display that in your JSP as html
In a servlet you can set the content type to application/pdf and write the binary data of the PDF back to the browser. Once the browser finishes reading in the data it should open the PDF.
