Can't pass bean or request attribute from servlet to JSP

Hi,
I have a web app that starts with a file upload page that uses commons io fileUpload, passes the info on to a servlet. Then the servlet passes its info on to a JSP.
I can upload the file onto the web app successfully. I also can call that uploaded file directly from the JSP (i.e. bypassing the servlet) without problem. But if I try to chain all 3 together while passing the url for the file directly as an attribute or as a bean containing file's url, I get premature end of file or can't find the property in the bean. I'm not sure what I'm doing wrong.
the error message:
org.apache.jasper.JasperException: javax.servlet.jsp.JspException: Premature end of file.

Thanks for the help!

Thanks for your reply, Ram.
I made the change but I get an error "Unable to find a value for "fileName" in bean of type beans.FileInfo"
Here's the bean:
package beans;
public class FileInfo {
private static String fileName;
private static String dirName;
private static String dName;
private static String url;
/** Creates a new instance of FileInfo */
public FileInfo() {
public static void setFileName(String fn){
fileName = fn;
public static String getFileName(){
return fileName;
public static void setDirName(String dn){
dirName = dn;
public static String getDirName(){
return dirName;
public static void setDName(String d){
dName = d;
public static String getDName(){
return dName;
public static void setUrl(String u){
url = u;
public static String getUrl(){
return url;
Pertinent parts of servlet:
String dirName = "C:/MyNBProjects/fileUploadApp/web/"; //save file to web app then convert to url so it can be called to show it on next page
String dName = "http://localhost:8084/fileUploadApp/faces/";
url = dName + fileName;
FileInfo fileInfo = new FileInfo();
fileInfo.setFileName("fileName");
fileInfo.setDName("dName");
fileInfo.setDirName("dirName");
fileInfo.setUrl("url");
request.setAttribute("fileName", fileName);
request.setAttribute("url", url);
request.setAttribute("fileInfo", fileInfo);
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/clinTrialsEditor.jsp");
dispatcher.forward(request, response);
jsp:
<jsp:useBean id="fileInfo" class="beans.FileInfo" scope="request"/>
<jsp:setProperty name="fileInfo" property="*"/>
url = <c:out value="${url}" />
//works; not part of bean
fileName = <c:out value="${fileName}" />
//works; not part from the bean
fileInfo.fileName = <jsp:getProperty name="fileInfo" property="fileName" />
//doesn't work
<%--fileName = <c:out value="${fileInfo.fileName}" /> //doesn't work
Can you spot the error(s)?

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

Parameter passing from servlet to jsp page

plz help me...
I m using as ...

and in jsp..
request.getParameter("string");

Hi Jaykumar
You should use
<%= request.getAttribute("sting") %> or
${string}
in your jsp. I think you are trying to retrive the parameter instead of attribute.

Populating bean attributes from servlet Request

I know that in a JSP, you can use
<jsp:setProperty name="p_filters" property="*"/>To populate the properties of a bean from parameters in a request.
Is there a reliable programmatic way to do this? Since I am using Tomcat, I could use
JspRuntimeLibrary.introspect(p_filters, request);But that relies on the servlet container's internal classes.
There really should be a way of doing this easily in a servlet as well as in a JSP! It should be part of the servlet standard, and the JSP standard <setProperty> tag should use that!

Well, that was buggy. Also, I've added common data types
 private static SimpleDateFormat[] df =
 new SimpleDateFormat("dd-MMM-yy"),
 new SimpleDateFormat("dd-MMM-yyyy"),
 new SimpleDateFormat("yyyyMMdd"),
 new SimpleDateFormat("dd/MM/yy"),
 new SimpleDateFormat("dd/MM/yyyy")
 public static Date parseDate(String d)
 Date result = null;
 for (int i = 0; i < df.length; i++)
 try
 result = df.parse(d);
 if (result != null)
 return result;
 catch (Exception e) // Ignore
 return result;

How can i pass a variable's value from PR to PFR

Dear all,
hope you are fine.
i would like to pass a variable's value from PR to PFR.
how can i do that.
please suggest.
in PR:
String transactionId = (String) vo_trans.first().getAttribute("Getnexttrans");
i would like to get this value to PFR.

Mofizur,
You can achieve the same using Session variable.
If u are not executing the VO after PR. Then you will be able to get the same value as u are using in PR
String transactionId = (String) vo_trans.first().getAttribute("Getnexttrans");
Note - You have a few of the threads left open, mark it as answered if solved.

Set request attributes from the request attributes

Using struts chaining actions.
When using chaining the requestAttributes are lost.
Is there a way to get all the request attributes and set them back to the request again?
if so how to do this?
Thanks.

Looks like nobody knows :(
It seems odd that nobody's tried to get InputSelectLOV or DataHandler working with a Struts app...
... anyway, on to finding out why the thing's throwing my releasemode away. This really is very like swimming through treacle :(

How can i pass more than 1 param to servlet to show blob image

Hi
my servlet expects 2 param to SELECt an image from a blob column
public class ImageBlobServlet extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
String ImageId = request.getParameter("id");
String TipImg = request.getParameter("tip");
OutputStream os = response.getOutputStream();
Connection conn = null;
try {
Context ctx;
ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/comp/env/jdbc/rhDS");
conn = ds.getConnection();
PreparedStatement statement = conn.prepareStatement("select FIT from " +
"RHH_FOTOS IMG " +
"where IMG.IDASSO = ? and IMG.TIM_COA = ?");
statement.setInt(1, new Integer(ImageId));
statement.setString(2, TipImg);
To display the image i tried to use:
<af:image id="ot1"
*source="/imageblobservlet?id=#{bindings.Con.inputValue}?tip=#{"EMP"}"*
shortDesc="Foto"/>
but i receive all content in the get of first param.
String ImageId = request.getParameter("id");
How can i pass one more then 1 param in EL.
Thanks in advance

Hello,
seems to me you're using wrong separator for the second param into your URL:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>
I think it should be:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>

How do I lookup an EJB 3.0 Session bean from servlet or JSP?

Does anyone knows how can I invoke an EJB from a servlet or JSP ?
I deployed a simple EJB on a Oracle Application Server 10g release 10.1.3 and I'm working with JDeveloper 10.1.3. I deployed the files via JDeveloper, and I didn´t specify any orion-ejb-jar.xml or ejb-jar.xml file
After deployment, the orion-ejb-jar.xml look like this in the server:
<?xml version="1.0" encoding="utf-8"?>
<orion-ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-ejb-jar-10_0.xsd" deployment-version="10.1.3.0.0" deployment-time="10b49516c8f" schema-major-version="10" schema-minor-version="0" >
<enterprise-beans>
<session-deployment name="HolaMundoEJB" location="HolaMundoEJB" local-location="HolaMundoEJB_HolaMundoEJBLocal" local-wrapper-name="HolaMundoEJBLocal_StatelessSessionBeanWrapper6" remote-wrapper-name="HolaMundoEJB_StatelessSessionBeanWrapper7" persistence-filename="HolaMundoEJB.home_default_group_1">

<assembly-descriptor>
<default-method-access>
<security-role-mapping name="<default-ejb-caller-role>" impliesAll="true" />
</default-method-access>
</assembly-descriptor>
</orion-ejb-jar>
I'm trying to invoke the ejb in a servlet by doing the following:
public void doGet(HttpServletRequest request, ....
Context context = new InitialContext();
HolaMundoEJB helloWorld =
(HolaMundoEJB)context.lookup("java:com/env/ejb/HolaMundoEJB");
String respuesta = helloWorld.sayHello("David");
When i invoke the servlet I catch a NamingException whose message says something
like this ....java:com/env/ejb/HolaMundoEJB not found in webLlamaEJB
I tried different paths for the lookup but nothing....
Can anyone help me with this topic? Thank you.

Please try the following code:
HelloEJBBean.java:
@Stateless(name="Hello")
@Remote(value={Hello.class})
public class HelloEJBBean implements Hello { ... }
hello.jsp:
Context ctx = new InitialContext();
Hello h = (Hello)ctx.lookup("ejb/Hello");
web.xml:
<ejb-ref>
<ejb-ref-name>ejb/Hello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<remote>fi.kronodoc.test.model.Hello</remote>
</ejb-ref>
i think you should also define jndi mappings for the references in orion-ejb-jar.xml and orion-web.xml but for some reason it seems to be working also without these.

Please help how to pass a JavaBean from servlet to jsp?

Hi there,
I have got a dispatch servlet and I want the dispatch servlet to get the data and store it in a JavaBean before dispatching to the appropriate JSP page. However, I don't know how to pass the javabean to the JSP when the servlet forward the request to the JSP. Is ServletContext.setAttribute() the only way to pass the javabean to the JSP page?
Thank you very much!
Edmund

You can use HttpServletRequest.setAttribute(String name, Object javabean) to set the javabean into the HTTP request that you are forwarding to the JSP.
In the JSP, you can access the Javabean using request.getAttribute(String name) and cast it to the right class.

Returning ResultSet from servlet to jsp - java.lang.NullPointerException

Hey all, i've been stuck on this for too long now...just trying to return a ResultSet from a servlet to jsp page.
Had a bunch of problems earlier...which i think were fixed but...now i get a "java.lang.NullPointerException" in my jsp page when i try to get elements from the ResultSet object.
Here is the latest version of my code:
Servlet:
String QueryStr="select ProdName from products";
Statement stmt=conn.createStatement();
rs=stmt.executeQuery(QueryStr); //get resultset
sbean.setInventory(rs); //set ResultSet in bean
req.getSession(true).setAttribute("s_resbean",sbean); //create session/request variable, set to bean
Bean:
package beans;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
import javax.sql.*;
public class SearchBean extends HttpServlet{
 private int searchFlag=0;
 private ResultSet inventory;
 public SearchBean(){
 public int getSearchFlag(){
 return searchFlag;
 public ResultSet getInventory(){
 return inventory;
 public void setInventory(ResultSet rs){
 this.inventory=rs;
 public void setSearchFlag(){
 this.searchFlag=1;
jsp:
<%@ page language="java" import="java.lang.*,java.sql.*,javax.sql.*,PopLists.PopInvLists,beans.SearchBean"%>
<jsp:useBean scope="session" id="s_resbean" class="beans.SearchBean" />
<% ResultSet categories=PopInvLists.getCat();
ResultSet manuf=PopInvLists.getManuf();
ResultSet supplier=PopInvLists.getSupplier();
ResultSet cars=PopInvLists.getCars();
ResultSet search=(ResultSet)request.getAttribute("s_resbean");
%>
<% while(search.next()){
 String pname=search.getString("ProdName");
%>
It craps out when i try to loop through the "search" ResultSet.
I can loop through the rest of the ResultSets no problem....just this one doesn't work because it's set in a servlet, not a simple java class.
Just to clarify, i am populating some dropdown lists on entry to the screen, which the user will use to perform a search. Once the search btn is clicked, the servlet is called, gets the request info for the search, performs search, and returns the resultset to the original screen. I want to eventually display the result under the search criteria.
Someone....Please Please please tell me how to get this working...it should be very simple, but i just can't get it to work.
Thanks in advance,
Aditya

req.getSession(true).setAttribute("s_resbean",sbean); //create session/request variable, set to beanHere you add an attribute to the session.
ResultSet search=(ResultSet)request.getAttribute("s_resbean");Here you try to get the attribute from the request. Naturally it isn't there because you added it to the session, not the request. Despite your comment in the first line of code, a session is not a request. And vice versa.

Sending attachment from servlet or jsp

Dear Friends,
I downloaded javamail api and I have seen the sendfile.java, which is used to send attachments. it is working fine. I can able to run that program from command prompt like this :=
c:>java sendfile [email protected] [email protected] mail.smtp.net c:/hello.java true
It is working fine from console (command prompt)
How can i execute that file on browser (i have to run as a servlet file or from jsp file).
please help me how can i pass the emailids, file etc., if i want to use this program as servlet file or as jsp program.
If anyone having idea, please share ur ideas.
your kind cooperation would be greatly appreciated.
Thanks in advance.
Looking forward to hearing from you.

which you can call as: sendmail.jsp?to=...&from=...&host=...&filename=...
so you may need to create a HTML file containing the necessary form.

Error message from servlet to jsp

Hi again,
I have servlet and check error on this servlet then i would like
to send error message to jsp page.Every error message will send to
same JSP page.So JSP must receive message from Servlet.Can i do this?
Please give me details and some sourcecode.I will appreciate for your helps.

you could do something like this..
request.setAttribute("error", stringErrormessage);
Then in the jsp just do
<%= request.getAttribute("error") %>
That will print an errormessage.
Basically, by setting anything on the request and then redirecting to that page you cn display it...

Database query ResultSet from servlet to JSP page

 Hi there,
 I have an Access 2000 database. I am running Apache and Tomcat on Windows Me.
 I would like to know if it is possible for me to use a Servlet to search the
 database (I know this bit is possible!), but then I would like the servlet to
 forward to a jsp page which will then display the ResultSet that the servlet has
 retrieved, i.e. when forwarding from a servlet to a jsp, is it possible for the
 jsp page to have access to the servlet's data? I know that it gets access to
 the response and request objects, but what about a ResultSet?
 Sorry it this sounds a little silly - i am a bit of a newbie.
 Thanks in advance for your help,
 SJ


HttpServletRequest.setAttribute let's you share data for a particular
 request. When you call forward you can store the resultset in the request.
 Make sure your JSP does close the result set though, because what you are
 trying to do doesn't sound good :)
 If you want to share data across the session, take a look at the HttpSession
 object.
 read through the servlet specification, it is fairly easy to read and will
 give you all the info you need

Creating files from servlets or jsp

The issue that I have is this
I've been working with eclipse, netbeans, tomcat, glassfish, servlets and jsps.
I have a little servlet/jsp web application that create few files from the servlet. Those files I need to make them visible to the browser because they are the end result of the servlets/jsp work.
When I run the server from netbeans/eclipse they deploy the war file into tomcat/glassfish server and run the app.
So far there is no problem here, just that.. the files created with the app are created into the project folder.
If I manually run the server, those files are created in the folder from I started the server, so what I did is get into the deployed/unpacked war and from there start the server.
Only that way I could make those files visibles to download.
Is there a better way to do this? (of course, it must be, but I don't know how).
What I want is, deploy the web-app and make the app create those files at the same folder of the web-app to allow those file could be downloaded, no matter from where or how the server is started.
In the near future I need to install few web-apps like this at the same server, so I can't still starting the server from the web-app folder (as I did it until now).
I read about the request.getContextPath(); but it return no the real address just the context address (something like "/my_app"), so when I use that address to create a file, what I get is something lik "/my_app/myFile.txt".
I hope you can give some advices of how to solve my issue.
Thanks in advance

Right now I know the absolute path to the tomcat/glassfish where the web-app is deployed, so I can use that address, but in the future that web-app could be deployed in another server and I can't know what address does it have.
I wonder if there exists a way to know the current absolute address of the web-app, or a way to create, "%this-web-app-absolute-addres%/someDir/myNewFile.txt"No, you're solving the wrong problem. Don't store files you create in the context of the web application, or even in the context of the application server. Store them somewhere else entirely. Then the person who configures the web application just has to set up the name of the directory where they are stored as a variable for your application.
