Handling List box element in JSP

Hi,
I have a List box which gets populated on the client side, depending on the user's activity on a form, when i finally submit the form, i want the list box with all the values to go to the server, Can anyone help me with the code on the server-side (JSP Scriplet) about how i can do this?
Thanks
Varadaraj

Assuming that by list box, you mean an HTML element using <select ...> tag,...
Only the currently selected values get submitted to the server. If thatis where you got kind of stuck.

How to access list box variable in jsp

hi.......I'm new to jsp ...pls help me with the following.....i've created a form with some list boxes ,text boxes and radio buttons.....now i need to access the variables of these elements in order to validate and display them.....what is the syntax in jsp for accessing the list box variable(or txt box or radio button)

You normally use a Servlet class for this. You can get request parameters by HttpServletRequest#getParameter() or #getParameterValues() then.
This is fairly trivial though. Please go through a decent JSP/Servlet book/tutorial first.

Cannot display Thai. character in List box elements

Hi all,
I have set the Fonts to Ms San Serif to all items in a form, all items seems can display Thai. character correctly. For List box, it can display Thai also, but the elements in the selections cannot.
Does any expert know how to fix this ?
Thanks!

Hi Kinghow,
Thanks for your reply!
The problem still can't solve after set the auto csv code select "Yes". The excel file still can't display Thai character.
Am i using a correct way to generate excel file? Do you have any suggestion to export data to excel using pl/sql?
If i removed below part, then the excel file working well.
htp.tableOpen(cattributes=>'border="1",bordercolor="BLACK",align="CENTER"');
for x in (select srd_line_prop,srd_line_dtl from schd_rptd where srd_queue_no=:P401031_QUEUE_NO and srd_line_prop='H' order by srd_queue_no,srd_line_no)
loop
htp.tablerowopen(cattributes => 'bgcolor="#81F7F3"');
for i in 1..pkg_wwe.split_count(x.srd_line_dtl,'|') loop
if i = 1 then
htp.p('<TD nowrap align="center" width="70px" > <font size="2" face="arial" color="#088A08">');
htp.p(pkg_wwe.split(x.srd_line_dtl,'|',i));htp.p(' ');htp.p(' ');
htp.p('</TD>');
else
htp.p('<TD nowrap align="center" width="70px" > <font size="2" face="arial" color="#08088A">');
htp.p(pkg_wwe.split(x.srd_line_dtl,'|',i));htp.p(' ');htp.p(' ');
htp.p('</TD>');
end if;
end loop;
htp.tableRowClose;
end loop;
htp.tableClose;
I really do not have any idea on how to solve this problem. Is really strange on 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">
Volunteer</dt>
of course that didn't work.
Thanks

I got it! Never mind!

Populate List Box

Hi,
          I am new to Weblogic 8.1 and was with .NET for last couple of years. I need to populate a list box in my jsp page. I have a database control method that returns a String array and this should be shown in the list box. I would like to know what is the efficient way to do this in 8.1.
          Thank you
          Jik

You have 2 choices, you can do all of the database work, and return all this to the web page, and make javascript repopulate all of the listboxes on the fly (faster for small datasets, ridiculous for large ones) , or otherwise you'll have to do another round trip to the server. You don't need to use javascript to do this, just resubmit and get the jsp to revalutae the values in the list boxes

Please help !!!! How to get data into dropdown list box

Hi all,
I want to display data from ResultSet object to drop down
list box in my JSP form.
How should I proceed ?
Please help me what should I do ?
Thanks for any help in advance.
savdeep.

dear hermione
it depends on the compexity of the application
i could also have suggested to use a JSP custom tag
that can populate the values stored in a table. I
guess u must have used that approach too.
But why to make the things complicated when they can
be done in an easier manner.
The author seems to be a beginner and telling him to
call Helper classes just to make a drop down is not
at all feasible.
what do u say?I believe it is best to start with a proper approach than finding quick solutions. Of course, JSTL sql tags allow you to execute queries within the JSP but they look cleaner in code.
Certainly, if the OP is a beginner in JSP (presuming that he has some background of core Java and OOP), I don't see any reason why there should not be a separate class with a well-defined responsibility. This will help the OP develop a thinking towards designing a good solution rather than simply patching in bits of procedural code to get the job done. There is a difference in doing something and doing in properly. :)
I suppose I am a little wary since I have been working too long maintaining code developed by others. A simple change in the requirement needs a lot of impact on several components.

Handling of list boxes

Hi All!
I am developing a web application for my organization. in one of the forms i have a list box where the user can select multiple entries from the listbox. now, i need to handle this situation in the next JSP page where the user is redirected to.
to make my problem more clear, i am providing a sample code of what i have and what i want:
Code on Page 1:
<form name=frm1 action=page2.jsp>
<select name=xyz multiple=true>
<option value = "1">ABC
<option value = "2">CDE
</select>
<input type=submit>
</form>
Now my problem is how do i access the multiple selections that may have been made by the user.
Please Help! ITS URGENT!!!!
Thanx in advance,
Rajat Aggarwal

When a multiple select box submits, it submits multiple name/value pairs.
eg
submit.jsp?xyz=1&xyz=2
You use
request.getParameter("xyz") only retrieves one value.
request.getParameterVales("xyz") retrieves an array of them.
String[] selectedOptions = request.getParameterValues("xyz");

How to add more elements in the list box bean

Hi,
I have created a list box bean on a seeded page. I have an array of 573 elements.
When I tried to add all those values in my list box, only 251 of those values got inserted in it.
Please suggest me how can I insert all the 573 values in that list box.
Regards,
Gaurav.

Thanks Gyan.
Below is the code for creating list box :
OAApplicationModule am = pageContext.getRootApplicationModule();
OAViewObject listVO=(OAViewObject)am.findViewObject("LocationsLOVVO");
OAWebBeanFactory list1 = pageContext.getWebBeanFactory();
OADefaultListBean list = (OADefaultListBean)list1.createWebBean(pageContext, OAWebBeanConstants.DEFAULT_LIST_BEAN, null, "LocationsList");
list.setListViewObjectDefinitionName("oracle.apps.irc.lov.server.LocationsLOVVO");
list.setListValueAttribute("LocationCode");
list.setListDisplayAttribute("LocationCode");
list.setSize(6);
list.setMultiple(true);
list.setName("Location");
OAMessageLayoutBean listboxbean = (OAMessageLayoutBean)webBean.findChildRecursive("AplmessageLayout");
listboxbean.addIndexedChild(list);
But it is not inserting all the location values in the list.

Gaurav.
