Passing information from one jsp to an included jsp

I have one jsp page that includes many other jsp pages (using the include page directive) [there are many good reasons to have these pages separate, else I would love to just make them one at this point]
I need to get information in jsp page 1 from the request. This information may or may not be there, may or may not be encrypted. If the information is not there, I am prepared to make an assumption. This said, my challenge lies in trying to do this once and make the information available to the included pages.
I am using version 1.0 of JSP and the include page, param solution does not work for me.
This is URGENT! Thank you in advance for any assistance.

Hi Michelle,
1. I'm using Jsp 1.1. I'm not how Jsp1.0 behaves.
Just try 2 or 3 depending on your need in waiting
for more input.
2. We can't pass data using include directive as:
<%@ include file="to.jsp"%>
3. We can pass data using include action as:
<jsp:include page="to.jsp" flush="true">
     <jsp:param name="fname" value="FirstName"/>
     <jsp:param name="lname" value="LastName"/>
     <jsp:param name="age" value="11"/>
</jsp:include>

How can I pass information from one portlet to another?

First, some background...
I am using Portal 5.0.2 and developing portlets using JSP/Java on a remote server.
I need to pass information from a portlet on pageA to another portlet on pageB, but I can't do it using the traditional methods, such as query string, session, cookies, etc. due to either portal framework limitations or because of functional constraints (basically, a user will not necessarily be logged in to the portal, but he can view anything available to the GUEST user). Here are the different ways I've considered using to save state and their limitations:
Query string: can't use this because portlets on remote servers don't have access to it
Cookies: if user disables cookies, code will not function properly
Session variables: limited to one user's connection with one portlet (i.e., can't access a session variable set in portletA from portletB)
Application variables: because the user may not be logged in, I have no way of uniquely naming variables, which is a necessity in order to maintain state for EACH user
User Settings: again, the user may not be logged in, so I can't use these
PCC: can't access client-side variables because server-side JSP executes first
Are my assumptions above correct? Has anyone had any success using one of these methods given the same constraints, or does anyone have an alternative solution? I'd certainly appreciate any help anyone could provide.
Thanks,
Jose

One possibility would be to use a Login PEI to set a unique UserInfo Name/Value for the user. I think in 5.0 each guest session is unique, so would have unique UserInfo. Then you could pass this value to your portlet (by specifying it in the web service) and use it as a key into a Application-scoped hashmap where you store your info. In other words, your Application variables option, but you have a way of uniquely naming your variables via PEI-set UserInfo.

Passing Information from one RS to another RS

How can we pass the information from one RS to another RS?

yes,from EM when I am testing the webservice it is returning the string properly .
In my ESB application I am calling this service thru a SOAP Service and I am using a FileAdapter to capture the result.Now to configure the RS shall i choose 'Generate WSDL from schemas' i.e. the request -reply option or 'Select Existing WSDL option'?I am choosing the first one.Now whn I am defining the rule there is a node mismatch in my source and target during mapping.When I am invoking the RS from EM i am getting some exception that "input is null".

How to pass information from one JSP to another JSP? help please

hi there
my question is how to pass some information such from one JSP to another one. for exmple, on one page there is a form, and i need to pass some values from the form to another jsp, or some values that were calculated on one JSP and need to be passed to another one. thanks

You can do this in several ways...here is a simple one...
When you call the second page url, use this
http://www.mysite.com?myVariableFromPageOne="hello"
on the second page use this:
String firstPageVariable = request.getParameter("myVariableFromPageOne");
Thanks

Passing information from one jsp to another

Hi,
I have a problem when trying to get information from a jsp page. Lets say that a jsp page has a textbox named "bannerurl" and it has the data "http://www.abcd.com?param1=2000?param2=3000". When I try to get the information in an other jsp file using request.getParameter("bannerurl"), I get only the following data - ""http://www.abcd.com?param1=2000". All information including and after the "&" is ignore. This could be because it is recognizing the information after the "&" as an other parameter. How do I solve this problem.
Thanks.

Hi
Are the two jsps below roughly doing what you want your application to do?

Passing information from one UIViewController to the next ?!

Hi all,
This is a great source of information and asking people who have been through my problems can help me solve a problem in hours that would take me weeks!
Anyways... I have these two UIViewController objects, it's all hardcoded at the moment but the 1st one is a simple list of people with a picture a name and a button saying "view".
When I click on view I'd like this view to send information (name of the person) to the second UIViewController so it can display it...
For this I have enabled an accessor (property) for a NSString var... this should in theory work but doesn't:
[PersonDetailViewController *personsDetails = [[PersonDetailViewController alloc] initWithNibName:@"PersonView" bundle:[NSBundle mainBundle]];
personsDetails.name = @"The Great Tiger";
\[self.navigationController pushViewController:personsDetails animated:YES\] ;
It just displays the default "label" text on my label...
Any thoughts? This should be a simple one...
Message was edited by: aussiezilian

HI, well what happens with the NSString property?
Somewhere need to be code that copies the property-value to the Label's text-property. Did you check if this code is beeing called each time the view is pushed onto the navigationController?

Passing data from one screen to another(web-dynpro) in SRM sourcing cockpit

HI Experts,
i am facing problem in passing data from one web-dynpro screen and assigning the data it to another web-dynpro screen.
my requirement is that when ever user selects a contract in PROPOSE SOURCES OF SUPPLY screen popup and press only assign only button, the data of the contract should be copied to the shopping cart.
i have already used the BADI BBP_DOC_CHANGE_BADI, but unfortunately it was not working.
so i tried to use the context, element and other web-dynpro fields to pass the data, i am able to pass the data from the popup to the second screen and able to assign it.
but when ever i deselect the shoppping cart which has been assigned with the data of the popup and select another shopping cart the data of the above shopping cart is cgetting changed.
i am unable to figure out the exact reason why this is happeing.i have written code in the ASSIGN ONLY button method to fetch the popup data and in the WDONMODIFYVIEW method of the second screen to assign the popup data to the shopping cart.
i have tried to bind the elements using the BIND_TABLE, BIND_STRUCTURE, BIND_ELEMENT, BIND_ELEMENTS methods, but nothing is working.
can anyone suggest me where i am making mistake and try to solve the issue.
Thanks
Tanveer

Passing data from one subreport to another subreport

Post Author: GISGuy
CA Forum: Formula
I have a report which is really a series of subreports with very few actually requiring a direct link to another. What I am trying to do is compare dates between different subreports and do conditional formatting to highlight where a dependant data source has an older date than the parent data source.
We use Crystal Reports XI release 2, and the data resides in ArcSDE & Oracle 9.
Any suggestions would be greatly appreciated.

When your tagline is about the size of your post, you probably didn't convey much.
You can pass values from one subreport to the next in the order they are placed in the main report by using shared variables, as in:
//1st subreportwhileprintingrecords;shared datevar MyDate := {table.date}
//2nd subreportwhileprintingrecords;shared datevar MyDate;if {table.date} = MyDate thencryellowelsecrwhite
Covers the theory, for specifics you have to be in your post.

How to pass data from one internal session to another internal session

hi all sap experts ,
How to pass data from one internal session to another internal session and from oneExternal session to another external session.
Except : Import and Export parameters and SPA/GPA parameters.
Tell me the otherWay to pass data ..
Plz
Thanks in advance

hi,
abap memory management u will understand about this concept.
the import /export parameter will help u that passing data between two internal sessions by using abap memory.
for syntax
Passing Data Between Programs
There are two ways of passing data to a called program:
Passing Data Using Internal Memory Areas
There are two cross-program memory areas to which ABAP programs have access (refer to the diagram in Memory Structures of an ABAP Program) that you can use to pass data between programs.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens (see below).
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse. For further information, refer to Data Clusters in ABAP Memory.
Filling Input Fields on an Initial Screen
Most programs that you call from other programs have their own initial screen that the user must fill with values. For an executable program, this is normally the selection screen. The SUBMIT statement has a series of additions that you can use to fill the input fields of the called program:
Filling the Selection Screen of a Called Program
You cannot fill the input fields of a screen using additions in the calling statement. Instead, you can use SPA/GPA parameters. For further information, refer to Filling an Initial Screen Using SPA/GPA Parameters.

How to pass data from one internal session to another

Memory Structures of an ABAP Program
In the Overview of the R/3 Basis System you have seen that each user can open up to six R/3 windows in a single SAPgui session. Each of these windows corresponds to a session on the application server with its own area of shared memory.
The first application program that you start in a session opens an internal session within the main session. The internal session has a memory area that contains the ABAP program and its associated data. When the program calls external routines (methods, subroutines or function modules) their main program and working data are also loaded into the memory area of the internal session.
Only one internal session is ever active. If the active application program calls a further application program, the system opens another internal session. Here, there are two possible cases: If the second program does not return control to the calling program when it has finished running, the called program replaces the calling program in the internal session. The contents of the memory of the calling program are deleted. If the second program does return control to the calling program when it has finished running, the session of the called program is not deleted. Instead, it becomes inactive, and its memory contents are placed on a stack.
The memory area of each session contains an area called ABAP memory. ABAP memory is available to all internal sessions. ABAP programs can use the EXPORT and IMPORT statements to access it. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
All ABAP programs can also access the SAP memory. This is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters are often used to preassign values to input fields. You can set them individually for users, or globally according to the flow of an application program. SAP memory is the only connection between the different sessions within a SAPgui.
The following diagram shows how an application program accesses the different areas within shared memory:
In the diagram, an ABAP program is active in the second internal session of the first main session. It can access the memory of its own internal session, ABAP memory and SAP memory. The program in the first internal session has called the program which is currently active, and its own data is currently inactive on the stack. If the program currently active calls another program but will itself carry on once that program has finished running, the new program will be activated in a third internal session.
Data Clusters in ABAP Memory
You can store data clusters in ABAP memory. ABAP memory is a memory area within the internal session (roll area) of an ABAP program and any other program called from it using CALL TRANSACTION or SUBMIT.
ABAP memory is independent of the ABAP program or program module from which it was generated. In other words, an object saved in ABAP memory can be read from any other ABAP program in the same call chain. ABAP memory is not the same as the cross-transaction global SAP memory. For further information, refer to Passing Data Between Programs.
This allows you to pass data from one module to another over several levels of the program hierarchy. For example, you can pass data
From an executable program (report) to another executable program called using SUBMIT.
From a transaction to an executable program (report).
Between dialog modules.
From a program to a function module.
and so on.
The contents of the memory are released when you leave the transaction.
To save data objects in ABAP memory, use the statement EXPORT TO MEMORY.
Saving Data Objects in Memory
To read data objects from memory, use the statement IMPORT FROM MEMORY.
Reading Data Objects from Memory
To delete data clusters from memory, use the statement FREE MEMORY.
Deleting Data Clusters from Memory

Passing information from JClient to View Object

What would be best way to pass information from JClient to View Object. I would like to implement security system, where view object would take information about what specific users can do (not oracle users, I would like to have one user to connect to database only) from an oracle table or stored procedure. Now I need to pass information about user: user name, IP, application etc. to View Object. I have two ideas for possible solution:
a) dynamic attributes
b) exporting methods (with custom interface)
Any suggestions ?

Passing Information From Socket to GUI

Hi, I'm making a chat client, but I'm having trouble passing information from server's input stream to my GUI. I made two threads, one for sending and one for receiving, and I start them both when I click "connect" after I log in to the server. So what happens is I run my program, the frame appears as I want it to, and then I click connect, and after a little wait the button "unclicks" (or w/e) and nothing happens. I don't know why I am not receiving the messages from the server. If I make the program "GUI-less" it works, I can both send and receive messages via the console. But in the GUI, where I am sending/receiving via my two TextAreas, it doesn't work. Here's my code:

            bw.outText.setText(bw.outText.getText() + newLine + messageOut);
            byte[] m = messageOut.getBytes();
            try {
                out.write((byte) 0x05);
                out.write(m);
            catch(IOException e) {
                System.out.println(e);
            String blank = "";
            bw.inText.setText(blank);
            sr.src = null;
class Receive extends Thread {
    InputStream in;
    SendAndReceive sr = new SendAndReceive();
    BotWindow bw;
    public Receive(InputStream inputIn) {
        in = inputIn;
        bw = new BotWindow();
    public void run() {
        while(true) { //thinking of doing while(sr.src != bw.submit)
            try {
                bw.outText.setText(bw.outText.getText() + (char)in.read());
            catch(IOException e) {
                System.out.println(e);
}So, to repeat my question, why isn't my GUI receiving the data being passed to it from the BattleNet socket? Also, am I taking the right approach on separating the send and receive methods and is my threading correct?

Just Look at this code...
while(true) { //thinking of doing while(sr.src != bw.submit)
try {
bw.outText.setText(bw.outText.getText() + (char)in.read());
catch(IOException e) {
System.out.println(e);
The problematic area is this code itself.
Try to read text Line by Line basis. You can do this by using readLine() rather than read().
The modified code should be like this:
while(true) { //thinking of doing while(sr.src != bw.submit)
try {
String TextRead=in.readLine();
String Prev_text=bw.outText.getText();
String new_Text=Prev_text + new_Text;
bw.outText.setText(new_Text);
catch(IOException e) {
System.out.println(e);
This would make the code easy to read and modify.
I have faced these kindaa problems during my JAVA project coding. However they have been solved by using a much simpler approach like the one I have used. Although they do the same thing, but anyhow it provides a better result for reasons quite unknown to me!!!

Passing Information From Server to GUI

Hi, I'm making a chat client, but I'm having trouble passing information from server's input stream to my GUI. I made two threads, one for sending and one for receiving, and I start them both when I click "connect" after I log in to the server. So what happens is I run my program, the frame appears as I want it to, and then I click connect, and after a little wait the button "unclicks" (or w/e) and nothing happens. I don't know why I am not receiving the messages from the server. If I make the program "GUI-less" it works, I can both send and receive messages via the console. But in the GUI, where I am sending/receiving via my two TextAreas, it doesn't work. Here's my code:
(I apologize ahead of time for posting so much code in a thread, I tried to cut it down as best as I could.)
actionPerformed method for connect and disconnect buttons (in BotWindow class)
public void actionPerformed(ActionEvent evt) {
        JButton src = (JButton)evt.getSource();
        if(src == connect) {
            try {
                bnet = new BattleNet("useast.battle.net");
                bnet.logIn("dynobot1", "test");
            catch(Exception error) {
                System.out.println(error);
        if(src == disc) {
            try {
                BattleNet bnet = new BattleNet("useast.battle.net");
                bnet.logOut();
            catch(Exception error) {
                System.out.println(error);
BattleNet class
import java.io.*;
import java.net.*;
public class BattleNet extends SendAndReceive {
    Socket sock;
    InputStream in;
    OutputStream out;
    Send send;
    Receive receive;
    public BattleNet(String server) {
        try {
            sock = new Socket(server, 6112);
            in = sock.getInputStream();
            out = sock.getOutputStream();
            send = new Send(this.out);
            receive = new Receive(this.in);
        catch(Exception error) {
            System.out.println(error);
    public void logIn(String username, String password) {
        byte[] u = username.getBytes();
        byte[] p = password.getBytes();
        try {
            out.write((byte) 0x03);
            out.write((byte) 0x04);
            out.write(u);
            out.write((byte) 0x0a);
            out.write(p);
            out.write((byte) 0x0a);
            receive.start();
            send.start();
        catch(IOException e) {
            System.out.println(e);
    public void logOut() {
        try {
            sock.close();
            in.close();
            out.close();
        catch(Exception error) {
            System.out.println(error);
SendAndReceive class (with Threads as subclasses)
import java.io.*;
import java.net.*;
import java.awt.event.*;
import javax.swing.*;
public class SendAndReceive implements ActionListener {
    JButton src = null;
    public SendAndReceive() {}
    public void actionPerformed(ActionEvent evt) {
        src = (JButton)evt.getSource();
class Send extends Thread {
    OutputStream out;
    SendAndReceive sr = new SendAndReceive();
    BotWindow bw = new BotWindow();
    public Send(OutputStream inputOut) {
        out = inputOut;
    public void run() {
        if(sr.src == bw.submit) {
            String newLine = "\n";
            String messageOut = bw.inText.getText();
            bw.outText.setText(bw.outText.getText() + newLine + messageOut);
            byte[] m = messageOut.getBytes();
            try {
                out.write((byte) 0x05);
                out.write(m);
            catch(IOException e) {
                System.out.println(e);
            String blank = "";
            bw.inText.setText(blank);
            sr.src = null;
class Receive extends Thread {
    InputStream in;
    SendAndReceive sr = new SendAndReceive();
    BotWindow bw;
    public Receive(InputStream inputIn) {
        in = inputIn;
        bw = new BotWindow();
    public void run() {
        while(true) {
            try {
                bw.outText.setText(bw.outText.getText() + (char)in.read());
            catch(IOException e) {
                System.out.println(e);
}So, to repeat my questions, SendAndReceive class, but I'm not sure if this is the right approach.why isn't my TextArea (BotWindow.outText) not receiving and setting it's text to the information from the server? Is my threading correct? Also, with the way I set up the threads, will the Send function be able to send in the midst of the receive function? I tried to set it up so that it could by implementing ActionListener in my SendAndReceive class, but I am not sure if this is the correct approach.
P.S. The reason I put this in Swing is because it works without a GUI/Swing components! If it will help, I will post the GUI-less program I made that works.
