How to get Multiple Values for a key from a session object?
Hi,
It might seem dumb but I am facing a problem here with the session object. I'll paste the session object's content from the netbeans "Local Variables" window for clarity -
Name Type Value
hsession StandardSessionFacade #66
session LWSFSession #69
inherited
attributes Hashtable #80
[0] Hashtable$Entry "cart"=>#115
key String "cart"
value DummyCart #115
item null
submit null
v Vector
[0] String Full Metal Jacket
[1] String As Good As It Gets
[2] String Tim
What I want is to get the values "Full Metal Jacket", "As Good As It Gets" and "Tim" from the session obejct?
The problem I am facing is that if I do a session.getAttribute("cart"), I'll get a single value in return. What will that value be? Will it be "item", "submit" or "v"? And if I want all the values in v above, how can I get them?
Thanks.
None of the above.
HttpSession.getAttribute() will return what you put into it using HttpSession.setAttribute(). In your case, it'll return an Object which you need to cast to DummyCart. Then you can access the data in DummyCart using the API of the DummyCart class.

Hi Gurus:
I have a layout for planning, where I can plan for 5 days of the week. I also have a day column (yesterday) where I have the actual values. Users want to edit/foecast the next 5 days values. I am using a Variable to get the Date column which uses the System Date. However, since I am getting just one date in the Function Module (Code given below), the remaining days are greyed out and I can not enter the forecast values. I would like the same variable to get a series of dates in the same function module. What changes do I nee dto make in the ABAP code so that the remaining columns (Date) becaoe available for editing??
The FM code I have to get "Today's Date" is as follows:
FUNCTION ZCSHFL_GET_TODAY.
""Local Interface:
*" IMPORTING
*" REFERENCE(I_AREA) TYPE UPC_VAR-AREA
*" REFERENCE(I_VARIABLE) TYPE UPC_Y_VARIABLE
*" REFERENCE(I_CHANM) TYPE UPC_Y_CHANM
*" REFERENCE(ITO_CHANM) TYPE UPC_YTO_CHA
*" EXPORTING
*" REFERENCE(ETO_CHARSEL) TYPE UPC_YTO_CHARSEL
data: ls_charsel type upc_ys_charsel.
ls_charsel-seqno = 1.
ls_charsel-sign = 'I'.
ls_charsel-opt = 'EQ'.
ls_charsel-CHANM = I_chanm.
ls_charsel-low = sy-datum.
insert ls_Charsel into table eto_charsel.
ENDFUNCTION.
I want to get the Yestarday's Date as weel as dates for next 4 days from Today for this variable which are being used in the layout. Can anyone suggest the code tor this please.
Thanks very much in advance......
Best.... ShruMaaHi,
What I understand you need to return those dates from function module using parameter ETO_CHARSEL , right? If so just use this code:
ls_charsel-seqno = 1.
ls_charsel-sign = 'I'.
ls_charsel-opt = 'BT'. "we are giving ranges, so days between...
ls_charsel-CHANM = I_chanm.
ls_charsel-low = sy-datum - 1. "...first day is yesterday
ls_charsel-high = sy-datum + 4. "...and last day is 4 days from today
insert ls_Charsel into table eto_charsel.
This way you provide 5 days starting from yesterday till 4 days from today.

Multiple values for one key in hashtable k, v
So, I know that java.util.hashtable (as of Java 1.5) uses separate chaining to handle collisions. What I want to know is how to get a certain value somewhere in that bucket if they all share a common key? Javadoc says I have to search it sequentially but doesn't say how.
OK, there's a lot of confusion on here for such a short thread :-)
Firstly, HashMaps pick which "bucket" to store your object in based on the hash value of your object (see Object.hashCode()). However, the actual object equality test (applied to the keys during a search) is based on Object.equals(). Therefore which bucket your object is in is irrelevant - the bucketting concept is just used as a way of quickly locating a subset of all the keys in the map which might match your search value. There could very well be just a single bucket in a map and it wouldn't change its logical behaviour.
This statement: "any Map including Hashtable, can only have a single (key,value) pair" is poorly worded. What it should say is that for any given key, a map can only hold a single value.
Really, you don't need to think about the internal structure of maps (i.e. buckets, etc.).
If you want to store multiple values for any given key, then make your value a list (java.util.List) and store your multiple real values inside that list. -
How to get multiple values from the list
I've a list of an item which I queried it from the database. I also created a button that will takes a selected items from the list when it was clicked. I used javabean to get the data from database.
<% // clicked on Select District Button
Vector vselectedDistrict = new Vector();
Vector vdistrictID = new Vector();
String tmpSelectDistrict = "";
tmpSelectDistrict = request.getParameter("bSelectDistrict");
if(tmpSelectDistrict != null)
// get multiple values from the list
String[] selectedDistrict = request.getParameterValues("usrTDistrict");
vselectedDistrict.clear();
vdistrictID.clear();
if((selectedDistrict != null) && (selectedDistrict.length != 0))
for(int i=0;i<selectedDistrict.length;i++)
vselectedDistrict.addElement(selectedDistrict);
vdistrictID = dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
for(int i=0;i<vdistrictID.size();i++)
out.println("district = " + selectedDistrict[i]); out.println("district ID= " + vdistrictID.get(i).toString());
%>
// get vdistrict from the database here......
<select name="usrTDistrict" size="5" multiple>
<% for(int i = 0; i< vdistrict.size(); i++)
%>
<option value="<%=vdistrict.get(i).toString()%>"><%=vdistrict.get(i).toString()%></option>
<%
%>
</select>
<input type="submit" name="bSelectDistrict" value="Select District">
Lets say the item that i selected from the list is 'Xplace' and I clicked on the Select District button,
what I got is this error message:
org.apache.jasper.JasperException: Unable to convert string 'Xplace' to class java.util.Vector for attribute usrTDistrict: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
So where is going wrong and what the message means?. Any help very much appreciated. ThanksThese are just guesses that might hopefully steer you in directions you haven't looked in yet.
I presume you used triangle brackets (< >) to avoid having the Jive Forum think it was the "italics" tag?
Are you certain this: dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
expects a Vector as its second parameter? And returns a Vector?
I don't believe you've shown how you use the javabean, or its code? Perhaps it should be rewritten to accept an array of strings instead of a Vector? -
Hey Guys
I'm trying to find a way to get multiple values using the following method
HttpSession.getAttribute(java.lang.String)
Here's the scenerio. Its a already written application and now i'm trying to make some changes. earlier in the jsp page a combo box was used and value was retrieved in the servlet using the getAttribute method of Session. Now I'm using a html multiple selection list and have to retrieve all the values selected in the list in the servlet. Can anyone please suggest me how to do that. HTTPRequest class has a method getParameterValues which will let me do that but i have to do is using HTTPSession.
Thanks for your time to read thisI'm not sure what you are trying to do. You can only use session.getAttribute to retrieve something that has already been stored in the session with a previous setAttribute. If you need to store multiple values under one attribute name using setAttribute, you can store an array, or an ArrayList or whatever type of Collection you want. The request.getParameterValues method is the only way you can retrieve form parameters than can have multiple values. If the servlet hasn't already processed these parameters and put them into the session for you, you have to use request.getParameterValues.

How to get the values for the Authorization Object Fields....
Hi Everyone,
I'm pretty new to the SAP Security and have been working on the Basis sides...I created a new role in PFCG and added a few transactions (ME13) and clicked on the Authorizations tab. In there, the authorization tree is in yellow and red. After providing the Org Values, only the yellow lights remain (apart from the green one ofcourse). Now how do we get the values for the different auth obj fields that are in yellow... say for example
Conditions COND
Maintain Condition: Auth. for Use/Appl./Cond.Type/Table V_KOND_VEA
Activity 03 ACTVT
Application KAPPL
Condition table KOTABNR
Condition Type KSCHL
Usage of the condition table KVEWE
Here the values for V_KOND_VEA fields e.g. KAPPL, KOTABNR etc are missing.
My question is how do we get these values in regard to the requirement provided by the client...is it the functional guys who provide these values or else how is a security person supposed to know it...
All the help in this regard is sincerely appreciated along with the awarding of points...Hey thanks Alex and Catastrophe for the quick response...
I'll be sitting with the functional team and reviewing the roles created.

How to get multiple values in a variable and apply filter at run time
Hi experts,
I want to get the deprtment information for an user. User may belongs to many department.
when user login at run time the filter should be apply for his departments.
users deprtments chnages frequently so we can't hardcode it.Hi,
Please refer to below post for one of the causes of this error:
Re: obiee-ebs data security integration
Also, can you check if you are getting NULL values for any rows. This might be the issue too. To verify this add ' and a.BUSINESS_UNIT_CODE is not null' in your query and check the results. Ensure you restart the BI services, clear your cache and then verify your result.

How to passing multiple values for a parameter of discoverer(url parameters
Hi All,
I am trying to pass multiple values for a parameter of disco report. I am trying to include my url for discoverer viewer report. the values has the following
'jeff,mark'
'sfophiee,angela'
Thanks and Regards
VenkatHello Venkat,
I know there are some problems with 10.1.2.0.2, maybe if you haven't done yet you can try with 10.1.2.2, assuming this version should be working for multiple parameter values :
OracleAS Discoverer 10.1.2.2 is installed with the following patch :
Patch 4960210 PLACEHOLDER BUG FOR AS/DS 10G R2 PATCH SET 2 10.1.2.2
So, once installed you can try adding your parameter as param_<parameter_name>='sfophiee,angela'
Hope this helps, otherwise feel free to log a Service Request to Support.

Need to concatonate multiple values for same key columns into one string
Hi...I'm attempting to use PL/SQL to read through a table containing more than one column value for a set of keys, and concatonate those values together into one string. For example, in the STUDENT table, for a STUDENT_ID there are multiple MAJORS_ACCOMPLISHED such as History, Biology and Mathematics. Each of the majors is stored in a different row with the same STUDENT_ID due to different faculty DEPARTMENT values.
I want to read through the table and write out a single row for the STUDENT_ID and
concatonate the values for MAJORS_ACCOMPLISHED. The next row should be another STUDENT_ID and the MAJORS ACCOMPLISHED for that student..etc.
I've hit a wall trying to use cursors and WHILE loops to get the results I want. I'm hoping someone may have run across this before and have a suggestion. Tks!!I think you are looking for string aggregation.
The following are the replies posted by me in the forum recently on the same case.
