Passing values Servlet
Gentlemans, I'm studying http techniques to optimize my application. And the security question happens. What the best form to pass parameters to an servlet? Today, I pass throught URL, for example:
http://www.test.com/test.jsf?value=myvalue&othervalue=myothervalue
But this form is so verbose, and could happens a security issue, which the best forms to pass parameters without expose my variables and values?
Make use of http POST request.
Also, you could find many tutorials on how to establish an http POST request in J2ME/MIDP on the web.

Servlet passing values to JSP and ClasscastException
I am using weblogic 5.1 to run my Servlets.
I want to know when I forward from a servlet to a JSP how do I pass
values especially Java Objects (Sometimes Objects of User written Java
classes).
Uptil now I have been putting all values in the session from where the
JSP picks them up, but somehow I have a feeling that this is not the
right way.
In a code I am putting a Java Object (It contains two attributes of
Java.util.Vector type) in the session so that the JSP to which I am
forwarding it to can use it I have put my class in the ServletClasses.
Intertestingly it runs well till the contents of the Vector are changed.
As the contents of the vector are changed, it throws ClassCastException
The StackTrace is as follows:
java.lang.ClassCastException

Can anybody please Help!!!!.
Thanks

Only can confirm your finding - the jsp is using a different class loader to the servlet that originally instantiated the object. There's the rub. I haven't figured out yet how to fix that. I can get the classloader but don't know how to get the runtime to use that class loader to perform cast.

Uptil now I have been putting all values in the session from where the

Suppose my servlet is forwarding to a jsp . What should it do in case an
exception happens in the servlet and wants to forward it to the jsp.
Putting the Exception object in the session is an alternative but I
wonder that is the best approach.
If someone knows a better way od doing it, please help.
Pankaj
You could probably use setAttribute
..before forwarding the control to JSP.
req.setAttribute("message", "Hello, world");
ServletContext app = getServletContext();
RequestDispatcher disp;
disp = app.getRequestDispatcher("Dispmessage.jsp");
Cheers,
Naggi

HOW TO PASS VALUE TO STORED PROCEDURE through page
Hi
I want to create generate next number on base of type. I have created stored procedure with passing three value input. If I am passing value manually through page then next number is generating. But I don't to pass value manually, I have to assign value internally as per database record.
Sameh Nassar: Create PL/SQL Function And Call It From Your ADF Application
I did same thing in my application,It is working,Output like that
Value = INV
Result= 26400080
Now I have to assign value TRANSCATION TYPE through bean class or assign another textbox value. I did in my program in the following ways
<af:inputText value="INV"
label="#{bindings.p_transaction_type.hints.label}"
required="#{bindings.p_transaction_type.hints.mandatory}"
columns="#{bindings.p_transaction_type.hints.displayWidth}"
maximumLength="#{bindings.p_transaction_type.hints.precision}"
shortDesc="#{bindings.p_transaction_type.hints.tooltip}"
id="it16" binding="#{InvoiceJobOrderBean.transacation_type}"
partialTriggers="it16">
<f:validator binding="#{bindings.p_transaction_type.validator}"/>
</af:inputText>
then I got the following error.
<MethodExpressionActionListener> <processAction> Received 'javax.faces.event.AbortProcessingException' when invoking action listener '#{bindings.generateNextNumber.execute}' for component 'cb2'
<MethodExpressionActionListener> <processAction> javax.faces.event.AbortProcessingException: ADFv: Abort processing exception.

it will be treated as hijacking. Admin will lock out the thread. and your problem is contrary to the thread.
coming to your problem,
did you ever get a chance to read the error it is self explanatory. or else goggle it out to understand.
It is not operation binding problem. while invoking the operation binding you are calling some db function from there you caught.
coming to your requirement,
create generate next number on base of type. please check will multi user environment it working properly or not. -
JSP Custom Tags, Tag Handlers, Passing values
Multiple questions here while I try to work with custom tags (its a requirement):
From what I have had so far - I have a .tld file, a .java file and a .jsp page.
(this is not a working version as I just got it from a website)
platform: tomcat on an xp box.
I was wondering if we can pass the parameters that are passed to the the jsp page (like blah.jsp?param1=value1¶m2=valu2 ) to the tag handler?
This is because the processing that I need to do in the handler would depend on what I have in the passed values.
Any help in letting me know where to place those files on the tomcat context root would help. Please see, I do have a couple of servlets running on the box also and they might be in the same context root.
Any good short tutorial link is also welcome as a short answer as I try to unravel the custom tags in jsp.I am using TomCat 5.5
What I need to do using tags is to build a web-page on the fly by polling a couple of different tables in the database.
This is to be done using a jsp and custom tag (requirement) which would be able to handle any resultsets. We also have to come up with pageContext attribute names and supply column names as those attributes. Thus we will have to come up with the meta data file and a tag library descriptor as well.
I found a helloworld solution on a website and was trying to modify it to meet my needs. But I guess I under-estimated the work that needed to be done in this one. -
How to Pass values from XML to JSP??? Urgent Please Help me
Hi guys,
I am new to XML, I want to pass values from XML to JSP. I have a xml file with attributes, I should send this values to a JSP file. How is it??? Please Help guys.... its very urgent. Please send me how to do it with an example or atleast any urls related that....
Looking for ur favourable reply.
Thanks in advance,
Sridharin a servlet :
parse your xml file (see how at the end of the post) and
put the values you want in the request attributes
request.setAttribute("value1", value1);
...redirect to the jsp
in the JSP:
get the wanted attributes:
String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

Pass value to an application ...
hi Gurus,
Is it possible to pass values to an external application using java code.[ no JSPs and servlets involved ]
Guide me!!!
Regards,
-NagsYes. Use the Runtime and Process classes:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Process.html
An example for listing a directory on a UNIX platform:
import java.io.*;
public class Test {
public static void main(String[] args) throws Exception {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(new String[] { "ls", "-alF", args[0] });
process.waitFor();
BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
for (String s = br.readLine(); s != null; s = br.readLine()) {
System.out.println(s);
}This simple code does not check for exit codes, or error messages.

Hi, I am calling a Background job in my program. I am using JOB_OPEN, JOB_SUBMIT and JOB_CLOSE FM to start a job. My need is to pass a value to the job program(job program doesnt have any selection screen values). Is their any way without creating variants each time to pass value to it.
Please advice.....Hello,
You can first use JOB_OPEN which returns job number. Then build ranges or parameters to use SUBMIT to call the program.
Eg: SUBMIT RM06BB20 AND RETURN
WITH S_EKGRP IN R_EKGRP
WITH S_EKORG IN R_EKORG
WITH S_FLIEF IN R_FLIEF
WITH S_KONNR IN R_KONNR
USER sy-uname VIA JOB w_jobname
NUMBER w_job_number.
Now use JOB_CLOSE.
Thanks,

Passing values from a FORM to another FORM
Hi,
I have to pass values from FORM "A" to FORM "B". What is the best way to do this?\
Can I use a GLOBAL variable?
Thanks,
Marc.I think he meant the global namespace.
You set a :global_your_name_here to a value and that value is available in your entire application. See the help file section on the global namespace for more information.
Forms parameters are parameters that you form picks up from the outside when it starts. The calling entity must supply them in the URL or they will be set to null. You set them up in the object navigator in the Parameters node. -
Script fails when passing values from pl/sql to unix variable
Script fails when passing values from pl/sql to unix variable
Dear All,
I am Automating STATSPACK reporting by modifying the sprepins.sql script.
Using DBMS_JOB I take the snap of the database and at the end of the day the cron job creates the statspack report and emails it to me.
I am storing the snapshot ids in the database and when running the report picking up the recent ids(begin snap and end snap).
From the sprepins.sql script
variable bid number;
variable eid number;
begin
select begin_snap into :bid from db_snap;
select end_snap into :eid from db_snap;
end;
This fails with the following error:

Even changing the select statements to:

Please Help.

Passing values from javascript in pop up window to parent jsp
Hi
I am trying to pass values from a pop up window to the main window that popped this child window , with the idea to have the parent window refresh itself with value from pop up window.But the values are not going through.I do a request on the hidden variable but when the parent
jsp refreshes , the variable is still null...
The following is the code i have .
Parent jsp:a.jsp
<form name='summary'>
<input type=hidden name=customerid value="">
<input type="button" class="textButton" name="action" value="customerlist" onClick="javascript:openWin('b.jsp','800','350')">
<script>
function openWin(loc, w, h) {
var newWin = window.openloc,"HTML",'dependent=1,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1,width=' + w + ',height=' + h);
newWin.window.focus();
</SCRIPT>
<%
String optionVal = request.getParameter("customerid");%>
var user = "<%= optionVal%>";
</form>
child jsp- b.jsp (pop up window)
<script>
function closer(){
var val = document.formname.id.selected.value;
window.opener.document.summary.customerid.value = val;
window.opener.location.reload();
</script>
<form name = formname>
<input type="text" name="id" value = ''>
<input type="button" class="textButton" value="select"
onClick="closer();window.close();">
</form>
Any ideas on what i am missing
Thanks

Passing Value from Crystal Report (special function) to Business View parameter
Friends,
Í have a scenario where i need to pass value from Crystal Report to a Business view's parameter.
Eg : CurrentCEUsername (func in crystal report)-- gives login user which i should pass to parameter in a Business view (used in the same report).
Will be able to explain more if required.
Thanks in Advance,
BharathI guess you got the picture wrong. User_id is not a report_level parameter .
In Data Foundation, below query is used..
select Acc_Number, Account_Group,User_id from Accounts where user_id={?User_id}
where in {?User_id} is the BV parameter...
The Filter was a solution. But it takes long time to Query all the data from DB and then filter at BV level.
How do i pass the CurrentCEUsername to {?User_id}
Value should ve CurrentCEusername always. so that query will be
select Acc_Number, Account_Group,User_id from Accounts where user_id=CurrentCEusername
It will restrict the data pulled from DB to BV .. right? -
How to avoid popup & pass value dynamically in 'F4IF_FIELD_VALUE_REQUEST' ?

This program pops up the window of search help First I want to surpress that window and Second I have no clue
( How to pass the input parameters as value eg. 20 to a given field as we pass manually )
Can some one suggest something here ?

We will be exposing the Input parameters and Output lists of the SAP Search helps (simple search helps only) as input output of a Webservice.
So I need to understand how can we exploit the SAP Search Helps ?
What function modules can take these inputs as structures and can provide the output in form of a table ?

Hi,
I want to pass value of kromosom which is an int array to myValue which is int. How to cast the kromosom?
myValue = kromosom;I want to pass value of kromosom which is an int
array to myValue which is int. How to cast the
kromosom?Just out of curiosity. How did you expect that to be possible? You have an array of many ints and now you want to squeeze all of them into just one int?
Or do you want to read one int from the array and assign it to an int variable? This is how you read the first one,
myValue = kromosom[0];
