Passing values from a jsp to a servlet
I have a jsp which has a search form for customers, first it lets you search by colour, giving options of red, white or all, then gives three options of what price. Im trying to get my servlet to read these choices, and display the results. I have a statement in my serlvet which says:
String price = request.getParameter("search preference colour");
and the statment in the JSP is:
<select name="search preference colour">
<option value="Red">red</option>
<option value="White">White</option>
<option value="All">All</option>
</select>
I need to know how to define which option has been chosen, and have the chosen results displayed. I tried an 'if' statement but it didnt seem to work. Thanks

i have a servlet from which i am passing result set values to a jsp page.Basically they are database records from a table named basic.
and these selective fields have to be dissplayed on jsp.i have tried incorporating values into session variables and using them on jsp.it works fine for single record but when there are multiple results it fails!! :(Learn JSTL and use tags. Scriptlet code in JSPs is a bad idea.

Passing values from a JSP to Action class
Hi,
I have one JSP in this I have two select boxes.
The first select box is populated with default values.
From the first select box I am selecting the value and moving to the other select box using java script.
Now the value in the second select box has to be submitted alongwith some other values which I am getting.
These values are to be submitted to a Action class and further to the form bean using struts.
In the form tag in JSP I am calling the struts action class.
The issue here is,I am able to get other values except the values in the second select box.
I am using simple JSP page to get form values and submitting.
I am not using struts tlds because of project constraints.
Please advise on how to pass these values.
Regards,
RamIf the value from the select box isn't submitted, then it's not inside the form. Check the HTML output of your JSP to debug this problem.

List Box-passing value from one jsp to another
I have a list box in a .jsp.
<SELECT name="name">
<option value ="Fred">Fred
<option value ="Michael">Michael
</select>
<input type="submit"
value="Names">
I need to send the name to another .jsp. I don't know how to receive it or send it. I am using form method="post". I need to use the name selected in a query in my next .jsp, so I can select all the data in that has that name in it. I am connecting to a database on the iseries. Do I have to use submit or can I use something else? I wanted to use a link like this.
<dt valign="left"><img src="bullet1.gif">

of course that didn't work.
ThanksI got it! Never mind!

Passing value from JSP to scriptlet
Hi
I am trying to find a way to pass a value from jsp to the scriptlets, i.e.
<c:set var="testValue" value="123" />
<%
System.out.println(testValue);
%>
the above code just demonstrates what I was trying to achieve, by passing the value from the jsp into the scriptlet.
Can someone tell me if there's an easy way to do this?
Thank you.Note, using scriptlet code on your page is generally something to be avoided. 99% of what you should be doing on a JSP page can be done with EL/JSTL. If you can't do it with EL/JSTL then it probably belongs in a servlet/bean.
I always aim for 100% scriptlet free jsp pages.
Having said that, I can still answer your question: EL attributes are stored in the scope - page, request, session, application
${testValue} is equivalent to pageContext.findAttribute("testValue").
The <c:set> tag example doesn't specify a scope, so therefore you could get it like this:
<c:set var="testValue" value="123" />
<%
String testValue = (String)pageContext.getAttribute("testValue");
System.out.println(testValue);
%>alternatively exploit the feature of the useBean tag that creates a scriptlet variable:
<c:set var="testValue" value="123" />
<jsp:useBean id="testValue" type="java.lang.String"/>
<%
System.out.println(testValue);
%>Note that the EL variable and the Scriptlet variable are initially pointing at the same String.
But changing the string in scriptlet code will change the value it is pointing at, while leaving the EL variable untouched.
If you have a List in scope, and sharing it between EL and scriptlet variables then any changes to the list would be reflected because they both point at the same List object.

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

The following is the code i have .
Parent jsp:a.jsp

child jsp- b.jsp (pop up window)

function closer(){
var val = document.formname.id.selected.value;

Passing variable from one JSP to another
Hi....
I am working on customizing Oracle Application(istore).
I need to pass variable from 1 JSP to another.
JSP 1 contains the following line of code:
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
How can I pass this to another JSP Page. The other JSP should take the 'soldtoCustPartyName' and find out the primary address country.
So please help me in getting variable passed from 1st JSP to next.
By default, 1st JSP is not fwded to 2nd JSP.
This is very very urgent...Please help.....When you push the submit button on jsp1 - it goes to jsp2?
ie
// in jsp1.jsp
<form action="jsp2.jsp">
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
<input type="submit">
</form>
//Then in jsp2.jsp all you need is
request.getParameter("soldtoCustPartyName");This will pick up the value that is coming from the hidden field on jsp1 -
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:

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? -
Anyone knows how to pass value from Java to Perl program?
Did you write the perl program? Can you change it? Or are you trying to interface to something that already exists? This will limit your options, of course.
Anyway the first option is simple. The java program does this:
System.out.println("This is a line of input.");The perl program does this:
while(<>)and in that block, $_ is assigned to each line of input.
Then you can invoke both like this:
$ java MyJavaProgram | perl MyPerlProgram.pl
