Getting Data to a Servlet

Hi, I someone with little experience with Java EE programming.
I have a simple web application consisting of jsp and servlets. A servlet generates an image based on a string which is displayed on a jsp page along with a form containing a text input and a drop down list to select a number from 0-9. I also have a seperate java program which generates the string and then requires the data entered in the form on the webpage.
My difficulty is how to get the data to and from the java program and servlet. JMS was recommended to me for this purpose and I've been investigating the Message-Driven bean example from the Java EE 5 Tutorial [The Java EE Message Bean|http://java.sun.com/javaee/5/docs/tutorial/doc/bnbpk.html] . I have adapted the java program to be part of the application client so that I can send the strings needed in the webapp straight to the message bean and grouped these two and the webapp as part of an Enterprise Application.
I was wondering how to get the information form the message bean to the servlet in the web application?
Also suggestions as to how to get the form information submitted in the jsp pages back to the java program (this bit maybe should be in a different forum?).
Thanks for your time,

How can i get an Applet transfer data to a servlet like a Form does?

it is clear that URL class provides way to connect to remote web resource. and furthermore i am trying to make an applet perform like a Form in html to send user data to a servlet. i may adhere a long name-value string to url sent by applet but this is not a good way to hide information like hidden variables. Is there any class in J2SE package that i can wrap those Form data and send them in the way Form does...?
cheers!

In your other post:
but i just don't want to build a string with serlet name followed by many NV pairs tthis is a GET request:
myURL?name=value&name=value
To use a POST

This still requires you to make a VP string that you write to an outputstream of the
URLConnection. There is no other way to do this unless in an applet.

How get data in servlet from selected recotrd

I want set on my UIX site new button which after click will invoke servlet. In this servlet, I need a method which get data from selected record and write it to file. I have two questions. What kind of button I have to use to send data from selected record on my UIX site and how can I get selected data in servlet (I don't know a method - request.getParameter("column_name") doesn't work) It's very important for me. Please anyone response ?

If you are using ADF you can how which row were selected using the following code
tableClients.setRowIndex(
Integer.parseInt(
(String)
tableClients.getSelectionState().getKeySet().iterator().next()));
client = (Client) tableClients.getRowData();
assuming that the <af:table> have a binding to a managed bean and that it have an "selection" facet and you include your command button in these facet
to write to a file check java.sun.com and look for BufferedWriter or BufferedOutputStream

Getting session information in servlet?

In Apache SOAP, org.apache.soap.rpc.SOAPContext can be used as a parameter to get at session data in your servlet. The JDeveloper web services publishing wizard won't expose a method with this parameter, saying that the XML Schema mapping and/or serializer is not specified. Is there an OC4J equivalent to get at session information?

Hi.
Most definitely possible. A few months ago I coded something very similar - jsp
form, submit to a servlet. I needed to get and set session info in both the
servlet and jsp. The code was very basic (ie no tricks involved) and worked
well. FWIW both my servlet and jsp were in the same webapp.
Good luck,
Michael

re what do I mean by...
I have one jsp page, that has a an html form on it with elements that get
passed to a servlet through a submit button on the form. I would like to be
able to get information about the session from within the servlet. Is that
possible?
Let me know if I'm not explaining myself properly and you need more info.
I'm relatively new to this stuff. But I'm learning! :>>>>

by a 'servlet being called from a jsp' ?

passing session attributes via the servlet call, how can you access the

Do you really want to execute different requests given input from the users? (e.g., enter a value in a text box and see the drop down list boxes change)

!!! Storing and Getting data from HashMap !!!

Hi ,
I have got a doubt if this is possible .. Please let me know if this can be implemented ..
I have a Process1 running which stores data into HashMap one by one from the Users.
Eg:
Key Object
1 ---> Karthik
2 ---> Raaghav
3 ---> Srikanth
and so on ..
Now what i internally do is i will wait for 5 min Duration (Session TimeOut).Once it is Over 5 min I will delete it from HashMap and Store it in a file ..
Iam also using WebServer Eg:Iplanet .
Now when i Shut down Iplanet all the data in the HashMap is Lost .
My Requirement is to write another Process2 which will be invoked as soon as Iplanet is ShutDown and This process has to read the data from HashMap which is not Timed out .And write it into the File ..
Q1)Please Let me know if this is can be Done ..
Task Done :
Process1 is already existing
Doubts :
Q2)If we write a Process2 will it spawn another VM or it will take the same VM that of the Process1.
Becos if it spawns another VM then I will not be able to get the data from HashMap of the Process1..
Thanks in Advance,
[email protected]

Thank You for the ..
But my prblm is that the Process1 is already Existing which reads and writes in to HashMap ( Not a Servlets) ..Its a Pure Java Code ..
And Now the requirement is another Process2 lets say which is put in thread (running in background )which gets the data from the HashMap of the Process1 or in other words Use the Same HashMap and not a different One ...
Process1 ------------------>HashMap
(write.java) (writes data ) /\
|
|
|(get Data)
|
|
|
Process2
I hope iam clear with my requirement ..
If Any further explanation Required Iam perpared to give ..Please let me know
thanks in advance ..

Getting data into an applet

I am creating an applet to draw graphs.
I have only made standalone applets before.
My data will come from a database.
The user will have the data selected for them, when they select the applet page, the data to be drawn will already have been selected.
i.e. I only need to give data across in the initialisation stage of the applet.
What is the standard way to get data into an applet?
By a giving a file path, by direct contact with the DB, with direct contact with another servlet or by giving the data in the HTML page the Applet is contained in.
(The data will come from the same server as the applet)
Maybe somone can point me to a tutorial on this?

I am currently developing some graph applets, too. At first I implemented direct database access via JDBC, but found out, that this ain't suitable, because you can get in serious trouble with customers who don't want to open database tcp ports in their internal firewall system which - from a security point of view - is a good decision.
So I gathered information about other methods to get data across the network. RMI needs own ports just like JDBC. Direct access to port 80 would be a good, so one could use Java's network capabilities. But this needs lots of coding on both ends (server and client-applet) and so takes time and is error prone.
Using SOAP leads to fat applets and so I gave XML-RPC a try. In my case I have an XML-RPC server written in PHP (using the PEAR module see: http://pear.php.net ) and in my applet I use the XML-RPC library from the Apache Group (see: http://ws.apache.org/xmlrpc/ ). This works just fine!
Pros:
- small library code in applet (less than 200 KB)
- only needs one network port. standard is 80 (http) which is almost everywhere available
- applet code is independent from server code and architecture, as almost every language has some XML-RPC module (other than RMI being a Java-only solution)
- free of charge & open source
- reliable
Cons:
- based on XML it can slow down things a bit when lots of data has to be sent over a slow network link - but that's more of a general problem in network application development
- other than SOAP/RMI you can not transmit/access whole objects but only data of primitive types (int, boolean, string, ..), so you have to wrap and unwrap your data
By now I am very pleased with the decision I made earlier this year. :)

Binary data in a servlet's doGet method?

Hi,
How to write binary data in a servlet's doGet method? Anyone, please help.

Use POST instead of GET to transfer binary data. For GET, you can only append the data in the QUERY_STRING and its length is very limited. so better use POST.

How to pass submitted Data from a servlet to EJB Session Bean in JPA

How to pass Data User submitted Data from a servlet to EJB Session Bean when using JPA :
Hi ,
I have a jsp page in which the user fills up the Data and submits it to the servlet :
Inside servlets i am getting all the parameters and setting it to the Entity Class .
Sample Entity class is shown below :
@Entity
public class Employee {
@Id private int id;
private String name;
public Employee() {}
public Employee(int id) { this.id = id; }
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}After calling setters of my Entity Class .
I am using JNDI lookup to call my session Bean method and pass this Entity class to the session Bean to persist data
Please let me know what will be the right approach :
1. Passing parameters whole as a Entity Class
that is
public void insertData(Employee emp)
}Or
2. public void insertData(String Name , int ID)
}

they are both right as they both work. Easy huh?
You might argue that if you have to set a lot of fields, use the entity as otherwise you get a method with a gigantic amount of parameters.

How to get Date and time of the server?

Hi, How can we get the date and time of the server while submitting a form using JSP? i.e I need the date and time , when the user is submittig a registration.
Uma

Upon receiving your data in your servlet, you can do the following to get the date,
Calendar calendar = Calendar.getInstance();
int dd = calendar.get(Calendar.DAY_OF_MONTH);
int mm = calendar.get(Calendar.MONTH) + 1;
int yyyy = calendar.get(Calendar.YEAR);
String dd_mm_yyyy = dd + "/" + mm + "/" + yyyy;
To get the time, simply take a look at the Calendar API to get the corresponding field.

Problem-Writing datas to a Servlet thro' URLConnection class

Hi,
Iam trying to post some string data to a servlet.
The servlet reads 2 parameters from url.And reads the xml string message thro post method.
So in the client program, I added those parameters to the URL directly like this,
"http://localhost/servlet/test?action1=value1&action2=value2" ,and created url object .
And using URLConnection iam trying to post the xml string.
But the servlet does not read the parameter values.Is my approach is correct?
client code:
package test;
import java.net.*;
import java.io.*;
import java.util.*;
public class Testxml{
public static void main(String ars[])
String XML="<?xml version='1.0'?><Test><msg>test message</msg></Test>";
String server="http://localhost/servlet/test";
String encodeString = URLEncoder.encode("action1") + "=" + URLEncoder.encode("something1")+"&"+URLEncoder.encode("action2") + "=" + URLEncoder.encode("something2");
try{
     URL u = new URL(server+"?"+encodeString);
     URLConnection uc = u.openConnection();
     uc.setDoOutput(true);
     uc.setUseCaches(false);
     uc.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
     OutputStream out = uc.getOutputStream();
     PrintWriter wout = new PrintWriter(out);
     wout.write(alertXML);
     wout.flush();
     wout.close();
     System.out.println("finished");
     catch(Exception e) {
     System.out.println(e);
Servlet code:
package test;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class test extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
     performTask(req, res);
public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
     performTask(req, res);
public void performTask(HttpServletRequest request, HttpServletResponse response) {
     try{
String action1=request.getParameter("action1");
String action2=request.getParameter("action2");
if(action1.equals("something1") && action1.equals("something2") )
     ServletInputStream in = request.getInputStream();
     byte[] buffer = new byte[1024];
     String xmlMsg = "";
     int len = in.read(buffer,0,buffer.length);
     if(len>0)
     while (len > 0 ){
               xmlMsg += new String(buffer,0,len);
               len = in.read(buffer);
     System.out.println("xml : "+xmlMsg);
This is not working.Even,it does not invoke servlet.Is this approach is correct?.
Thanx,
Rahul.

Sending data to a Servlet. EOFException and StreamCorruptedException.

Hi!
I have a small servlet that receives some text from a client, and returns a response. The problem is that when i try to receive the data in the servlet, I get and EOFException. And when the client tries to read the response, a StreamCorruptedException is thrown. Can anybody please point me in the right direction here?
The code for servlet is as follows:
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          DataInputStream in = new DataInputStream((InputStream) request.getInputStream());
          String message;
          String text = null;
          try {
               text = in.readUTF();//EOFException thrown here!
               message = "100 ok";
          } catch (Throwable t) {
               message = "200 " + t.toString();
          response.setContentType("text/html;charset=UTF-8");
          response.setContentLength(message.length());
          in.close();
          PrintWriter out = response.getWriter();
          out.println(message);
          out.flush();
          out.close();
          System.out.println(". Received text: " + text == null ? "none" : text);
     }And the code for the client:
     @Test
     public void test2() throws IOException, ClassNotFoundException {
          String input = "This text is to be sent";
          URL serverURL = new URL("http://localhost:8080/myURL");
          URLConnection con = serverURL.openConnection();
          con.setDoInput(true);
          con.setDoOutput(true);
          con.setUseCaches(false);
          con.setRequestProperty("Content-Type", "application/x-java-serialized-object");
          OutputStream outstream = con.getOutputStream();
          ObjectOutputStream oos = new ObjectOutputStream(outstream);
          oos.writeObject(input);
          oos.flush();
          oos.close();
          InputStream instr = con.getInputStream();
          ObjectInputStream inputFromServlet = new ObjectInputStream(instr);//StreamCorruptedException thrown here ("invalid stream header")
          String result = (String) inputFromServlet.readObject();
          inputFromServlet.close();
          instr.close();
          System.out.println(result);
     }The EOFException is thrown at the line text = in.readUTF(); in the servlet, and the StreamCorruptedException is thrown at ObjectInputStream inputFromServlet = new ObjectInputStream(instr); in the client. What is wrong here?

Your server reads a UTF-encoded String with readUTF().
So your client should write a UTF-encoded String with writeUTF().
Your server writes lines with PrintWriter.println().
So your client should read lines with BufferedReader.readLine().

where ebeln = i_mseg-ebeln.
    append i_ekpo.
endselect.
endif.
      OR
if i_mseg[] is not initial.
select zzlcno zzlcdt
into corresponding fields of i_ekpo from ekpo
