Dynaic Dropdown list in JSP

Hi all,
I have a web application in JSP and Tomcat, Microsoft Access is used as a database. On my application I have a dynamic drop down list which geneates all our client list from database. The reason why I am calling it dynamic is because the user can generate as many drop down list as they want based on their need so that they can record their time spent with those client.
Now the users are demanding that they want the web application to remember the clients they have selected last time they logged in which could be 7 or 10 drop down list with the client selected from the list. Now how can put this into programming? Can I use javascript to do that or JSP? Or do I need to use cookies. Can anyone suggest me how to use cookies.
Thanks

you can do it via JSP: you store users selections in the database (pesistent cach) and reuse them when needed but this is complex and needs more db space.
you can also do this using cookies. see some examples here http://www.javascriptkit.com/script/cutindex7.shtml

How to create a JSP dropdown list in the latest Early release

Hello:
this is probably an easy question. I am trying to create a dropdown list in a JSP form from a data control like "employee id". just dragging the data control attribute does not seem to have any effect in showing the drop down list when the JSP page is run.
What is the missing factor?
Thanks in advance for the help.

Changing dropdown list selected value in JSP

I would like a dropdown list to load with all values in a database table, which is no problem. But, I would then like it to display a selected text value from that list, depending on the value returned by a SQL query. As an example, say I was looking-up someone's personal data and there was a dropdown list that listed all the possible hair colors. If this person had been entered as having blonde hair, I want the dropdown list to display blonde at page load, but give the user the option to select another color if a change is needed.
Thanks in advance for ur help.

<option value="<c:out value="${currentchoice}"/>"
    <c:if test="${currentchoice=='db_value'}">
        SELECTED
    </c:if>

Not All Items Appearing In Dropdown List

Hi,
You have a newbie here. I am trying to populate a dropdown list in a JSP with the following code, but not all the records are being displayed (approximately 4900 records are displayed). The Submit button that follows this Select tag is not being displayed, nor are any error messages being encountered. The last Option tag is incomplete. Any clues?
Thanks,

You have 4900+ records?? I'd say there was some exception being thrown somewhere, either you're running out of memory or something. Your response isn't coming completely which indicates that your output was interrupted but since it had been committed, the server couldn't redirect to an error page or display the exception or stack trace.
Check your logs, there'll definitely be something there.

it seems the second dropdown couldn't get the value from the first dropdown selection.
I wonder jdbc connection in the first dropdown still alive when the second dropdown list turns.
is it easy to use Servlet with the two dependent dropdown list?
thanks

Split Values in a dropdown list

Hi friends
i am stuck with a problem for which i need your help.i will list it out as below.
i am having a dropdown in my jsp page a ComboBox. The values in the dropdown are in the form
After 10 minutes
After 20 minutes
After 30 minutes
Before 5 minutes
Now when the user selects a value in the dropdown list ex. After 10 minutes. This value needs to be fetched and i have to retrive 10 & minutes seperately from the string "After 10 minutes" and the values should go into two different colums of 2 tables in the database.
I cannot use a DTO to set these values since the values will be combination pair of value & timetype.
What should be my approach here.
should i use a Hashmap or a Hashtable or some list so that i can send these values from the Action class to the Session Bean method.
please let me know what needs to be done in this case.waiting for a positive reply from your side.
Thanks & Regards
Vikram K

Create your own object which can store the different values and override the toString() method to display "After 10 Minutes" etc.
i.e.
private class MyClass {
   private int unit;
   private String measurement;
   public MyClass {
      super();
   // Getter and Setter Methods for fields
   public String toString() {
      return "After " + unit + " " + measurement;
}Then you can create a custom ComboBoxModel that contains your list of custom objects. Then it's a simple case of adding an ActionListener to the ComboBox to see which object the User has selected so you can then use the getter methods to pull the info you need and populate your table.

Blank line in DropDown List box

I have a case where I want to add a blank entry in a drop down list box that is bound to a database table. I want the blank to be the default, then the user can select the bound values if desired. How do I do this without binding the drop down box to a prepopulated array?

Hi
Go to the JSP source of that page and add
<f:selectItem itemLabel="None" itemValue="0"/> before
the line <f:selectItems binding="#{Page1.dropdown1SelectItems}" ....
With this you can deselect the previous selection by selecting None from the dropdown list. You can also use blank spaces instead of None.
Thanks

Displaying a list in JSP

Hi guys,
I'm struggling to find any examples of how to display a list of data in a custom JSP page. I will have some type of holding object to contain an array of BPM Objects. I would like to display one table row in the JSP for each object.
Does anyone have any examples of what format the instance variable should be and how i can map this into the attributes and iterate over this in the JSP.
thanks!
Neil

Here is some js code that calls the method 'getByRegion' on the myInfo view object, that I had passed into the jsp. Here is an example of how to populate a Dropdown list in the jsp, with the returned values... Its not on the same line as what you wanted, but will give you an example of using ajax to call a bpm method.
function regionSelect(regionValue){
     var sel = document.getElementById("entity");
     sel.options.length=0;
     var myurl = '<f:invokeUrl var="myInfo" methodName="getByRegion"/>';
          $.get(myurl, {name: regionValue}, function(data){
               for(i=0; i<data.length;i++){
                    sel.options=new Option(data[i].key + ' - ' + data[i].value,data[i].key, false, false);
          }, "json");
And the BPM Method code: Note, its returning a JSON string here.
This takes a java.util.map (requestParams) as an input argument.inAr as String[] = String[](get(requestParams, arg1 : "name"))
inVal as String = toLowerCase(inAr[0])
entity as String[]
entityId as String[]
sql as String = "select ENTITY_ID, ENTITY_DESC from vm_opts_coun_reg_entity where region = '" + toUpperCase(inVal) + "' order by entity_id"
for each row in executeQuery(DynamicSQL, sentence : sql, implname : "AppDB") do
     entity[] = String(row["ENTITY_DESC"])
     entityId[] = String(row["ENTITY_ID"])
end
retString as String = "["
for i in 0..length(entityId)-1 do
     key as String = entityId[i]
     value as String = entity[i]
     retString = retString + "{\"value\" : \"" + value + "\",\"key\" : \"" + key + "\" },"
end
if length(retString) > 1 then
     retString = substring(retString, first : 0, last : length(retString)-1)
end
retString = retString + "]"
return retString
HTH!

Dropdown list from the recursive table in DB2

Hi
I need to create a dropdown list that looks like this in my JSP:
Root
BaseChildA
ChildB
ChildC
BaseChildD
ChildE
ChildF
I have to create it from the recursive table in the database, with columns that show parent-child relationships like this:
child parent
root
A root
B A
C A
D root
E D
F E
Does anyone have an algorithm for doing this?
Thanks!!

I assume you just need to get the data and don't need instruction on how to create a dropdown list. (If you do need that instruction, go look for an HTML site -- there are lots.) Anyway, aren't you just going to get all the data from the "child" column? That would be the easiest way to get the data. But if you need to get the data in the order you showed there, look into whether your database can have a query that gives that. It's often called a "bill of materials explosion" or something like that.
