How to retrieve attribute value from my JSP?

My servlet needs to redirect to a JSP. Before that, I set an attribute value.
getServletContext().setAttribute("filename",templateFile);
RequestDispatcher rd = getServletContext().getRequest...
rd.forward(request, response);
In my JSP, this is how I want to retrieve it:
<%
String filename = (String)request.getAttribute("filename");
if (filename != null)
%>
<%= filename %>
<%
else
%>
it is null
<%
%>
But the value is always null? Do I need any tag or declaration on the top of my JSP?

Can i set attribute for list and get that list using request.getAttribute() in jsp?
ex.
in action
List plist;
plist = ...
request.setAttribute("plist", plist);
to get this value in jsp
<%
List plist = (List)request.getAttribute("plist");
%>
is this code is allowed?

How to get attribute value from standard page ?

Hi,
How to get attribute value from standard page ?
String str = (String)vo.getCurrentRow().getAttrbute("RunId");
But this value is returning a null value ....
Can anyone help me to get this attribute value which is actually having a actual value .

getCurrentRow() would always return null if no setCurrentRow() is used.
Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
vo.reset();
vo.next();

How to retrieve the values from a table if they differ in Unit of Measure

How to retrieve the values from a table if they differ in Unit of Measure?

If no data is read
- Insure that you use internal code in SELECT statement, check via SE16 desactivating conversion exit on table T006A. ([ref|http://help.sap.com/saphelp_nw70/helpdata/en/2a/fa0122493111d182b70000e829fbfe/frameset.htm])
If no quanity in result internal table
- There is no adqntp field in the internal table, so no quantity is copied in itab ([ref|http://help.sap.com /abapdocu_70/en/ABAPINTO_CLAUSE.htm#&ABAP_ALTERNATIVE_1@1@]).
- - Remove the CORRESPONDING, so quantity will fill the first field adqntp1. ([ref|http://help.sap.com/abapdocu_70/en/ABENOPEN_SQL_WA.htm])
- - Then loop at the internal table and move the quantity when necessary to the 2 other fields.
* Fill the internal table
SELECT msehi adqntp
INTO TABLE internal table
FROM lipso2
WHERE vbeln = wrk_doc1
 AND msehi IN ('KL','K15','MT').
* If required move the read quantity in the appropriate column.
LOOP AT internal_table ASSIGNING <fs>.
CASE <fs>-msehi.
 WHEN 'K15'.
 <fs>-adqnt2 = <fs>-adqnt1.
 CLEAR <fs>-adqnt1.
 WHEN 'MT'.
 <fs>-adqnt3 = <fs>-adqnt1.
 CLEAR <fs>-adqnt1.
ENDCASE.
ENDLOOP.
- You could also create another table with only fields msehi and adqntp and then collect ([ref|http://help.sap.com/abapdocu_70/en/ABAPCOLLECT.htm]) the data to another table.

How to get attribute value from an object inside an object in Xpress

Does anyone know how to get an attribute value from an object in Xpress in a workflow? I have an object structured as follows:
<ResourceInfo accountId='mj628' tempId='3483372b787ce7dd:-5d99a0c5:130cb238483:-3600'>
<ObjectRef type='Resource' name='Google Apps'/>
</ResourceInfo>
I need if possible to get the name='Google Apps', which is inside the ObjectRef, so I guess its an attribute value of an object inside an object.

If the ResourceInfo object is accessible in a variable, i.e. named "myResInfo", you just have to check the Java API and call the relevant method:
<invoke name='getResourceName'>
<ref>myResInfo</ref>
</invoke>

How to retrieve 2 values from a table in a LOV

Hi
I'm pretty new to APEX. I try to retrieve two values from a table using a LOV. I have a table named DEBIT with then columns SITE, NAME and KEY
I want to display NAME to the user in a list. When the user select an item from the list, I want to retrieve the data of the SITE and KEY column of this item in order to launch an SQL command based on this two values.
How to retrieve thes two values whant the user chooses an item from the list ?
I apologize for my english, being french.
Regards.
Christian

Christian,
From what I understood about your requirement, you want a 'select list with submit' which displays "NAME" and based on the value selected, you want to get the corresponding values for "SITE" and "KEY" from the table.
Step 1: Create a select list with submit, say P1_MYSELECT 
Use something like this in the dynamic list of values for the select list: 
SELECT NAME display_value, NAME return_value
FROM DEBIT 
Step 2: Create a page process of type PL/SQL block. Also create 2 hidden items P1_KEY and P1_SITE. 
In the PL/sQL, write something like:
DECLARE
v_key DEBIT.KEY%TYPE;
v_site DEBIT.SITE%TYPE;
CURSOR v_cur_myvals IS
 SELECT KEY, SITE
 FROM DEBIT
 WHERE NAME = :P1_MYSELECT;
BEGIN
OPEN v_cur_myvals;
LOOP
 FETCH v_cur_myvals
 INTO v_key,v_site;
 EXIT WHEN v_cur_myvals%NOTFOUND;
:P1_KEY := v_key;
:P1_SITE := v_site;
END LOOP;
CLOSE v_cur_myvals;
END; 
Then you can use these values for whatever purpose you need to.
Hope this helps.

How to get attribute values from one view to another

HI all,
Thx in Advance..
I have 2 view like v1,v2.In v1 i used one attribute values from "get single attribute" method.And i need the same values in v2 screen.For this i did in v1 outbound plugs , i mentioned the parameter name . How can i get the same values in v2.

Hi chandru ,
you said you declare the parameters in the Outbound Plug of V1. now go to view V2 inbound plug Tab and creat one inbound plug
double click on the plug name .it will navigate you to the event handeler method . Now add the outbound parameter variables in the
parameters
For example : V1firing the navigation plug
a type string " defined in parameter
wd_this->fire_out_to_view2_plg(
    a =      'ABCD'                           " string
you can retrive the value freely in v2 inbound event handeler
a type string " defined in parameter
*   set single attribute
    lo_el_context->set_attribute(
      name = `TEXT`
      value = a )." here you will get the 'ABCD'.

How to retrieve the values from PL/SQL table types.

Hi Every one,
I have the following procedure:
DECLARE
TYPE t1 IS TABLE OF emp%ROWTYPE
INDEX BY BINARY_INTEGER;
t t1;
BEGIN
SELECT *
BULK COLLECT INTO t
FROM emp;
END;
This procedure works perfectly fine to store the rows of employee in a table type. I am not able to retrieve the values from Pl/SQL table and display it using dbms_output.put_line command.
Can anybody help me please!!!!!
Thanks
Ahmed.

You mean, you can't add this
for i in t.first..t.last loop
dbms_output.put_line(t(i).empno||' '||t(i).ename||' '||t(i).job);
end loop;or you can't add this
set serveroutput onor maybe, you are working in third party application where dbms_output is not applicable at all?
You see, not able like very similar it is not working - both are too vague...
Best regards

How to retrieve the values from a LinkedList

Hello,
I have just put this question in java programming forums by mistake...I think that it should be here ...
I have created a LinkedList to store the results of a query to a database.
These reasults are decimal numbers and then I want to sum all these numbers to be able to make the average.
But when I try to retrieve the values of the Linked List I always receive an incopatible types error..
Here is an extract of my code in a jsp page.
LinkedList Average = new LinkedList();
String Media = rst.getString(10);
Average.add(Media);
int Size = Average.size();
double Sum = 0.0;
for (int i=0; i<=Size; i++)
double Result = Average.get(i)
Sum = Sum + Result;
}If I try to retrieve the value of only one node from the list , I can just putting <%=Average.get(i)%>...but..how can I retrieve all the values (they are decimal numbers) to be able to add them?

If you want to sum all the values, is there any reason you just don't retrieve the sum from the database rather than the list of values?
anyway
List average = new LinkedList();
while (rst.next()){
// retrieve the number:
String mediaString = rst.getString(10);
Double media = Double.valueOf(mediaString);
// or maybe like this if it is a number in the database
Double media = new Double(rst.getDouble(10));
average.add(media);
doubleSum = 0.0;
for (Iterator it = average.iterator(); it.hasNext(); ){
Double result= (Double) it.next();
doubleSum += result.doubleValue();
}

How to retrieve multiple values from a DB Adapter to a Web Service

Hello,
I'm creating a login WS that receives the username and password and returns the user status, full name and a set of permissions (the number of permissions varies among users).
In order to do that i've created a DBAdapter that is calling a PL/SQL procedure. This DBAdapter is connected to the login Web Service through a mediator.
I have two problems:
1 - I don't know the type of variable that the PL\SQL procedure should return. Like I said I need to retrieve an undefined number of values from a table (user permissions). How can I do this inside a PL\SQL procedure? What kind of structure should i return?
2 - How can i assign a multiple value variable (the permission variable) in the mediator? Is the mediator going to identify that this is variable is multiple valued and add automatically a for-each statement?
The Oracle DB version im using is the 11.1.0.7.0 and the Oracle SOA Suite 11.1.1.3.0.
Thanks in advance,
Paulo

Hey guys,
thanks for your help.
I've created a userdefined type and sucessfully retrievied from the PL\SQL procedure multiple values. I have also mapped this values with the web service.
Even though everything's working fine i would like to understand if it is also possible to use the XMLType to return these values. I ask this cause I don't no if by returning a XMLType i can explicitly map the XML elements inside the mediator component.
If possible what are the main advantages/disavantages between using XMLType and Userdefined Types?
Paulo.

How to retrieve constants value from compiled code in jar file?

Hi everyone,
I've been looking for a way to solve this for a week now, without any much success... and I've finally decided to ask the Java gurus for a solution! :-)
Here's what I am basically trying to do:
I have several jar files in which there are only compiled code (.class).
In every class, there are 2 constants (declared as static final String) that I would like to retrieve (one is the version and the other the date of the last modification).
My goal is to print a list of all the classes in the jar files with the values of these 2 constants for each class.
The solution that I have right now to do this does not work properly: for now, I read all the elements of the classpath, check if these are jar files, and if so, I look into each one and load all the classes one by one and print the results.
The problem with this is that it uses the method Class.forName(className) and as some classes are unfortunately present in many jar files (2 or 3 copies), once the classes have been loaded, then it won't be "reloaded".
Without the possibility to "reload" these classes, I cannot see inconsistencies in the versions of the classes present in the jar files.
I have read many articles, and I thought that I could then use a custom classloader and create a new instance of this classloader for each jar file.
2 problems with this:
- according to many posts in the different forums I have read, the jar files should not appear in the CLASSPATH (but this would be easier for me if I could use it...)
- some classes will not be loaded if some classes (present in other jar files) are not loaded... and this makes things really really complicated to implement...
So, I thought that I was maybe doing this the wrong way, and that there might be an easy way out of this...
In fact, I do not need to load the classes... all I need to do, is take a sneak peek at the constants and print their values... and that's it!
Somehow, I think that this is possible to retrieve the values of compile time constants (declared as static final String) as I can see that with Eclipse (when opening a jar file).
So, my question is: how can I do that within my java application?
Or maybe there is another easier solution to do what I need?
Thanks in advance for your help!

 Hope you will reply soon...
 Thanks in advance

Hey, I got a doubt that who will call the print method in the same program and what about the g.drawString() it is showing any output effect. Finally how the variable n will get initializing to 0 and 1 for two times respectively. Can u please elaborate on this...

How to access attribute value from another VO using groovy?

Hello, I am using JDeveloper 11.1.2.3.0
I read a lot of information about this but still I am missing something. I am trying to set the value of a bind variable through Groovy expression in my VO. I want this Bind variable
to have the value from an attribute from another VO. I tried ''adf.object.MyAppModuleImpl.findViewObject('Users1').currentRow.Iduser''
I am getting "oracle.jbo.expr.JISyntaxError: Variable MyAppModuleImpl not recognized". I tried with 'MyAppModule' only but the result is the same.
Can anyone help please?
Thanks

How to extract Attribute Value from a DBC file with LabWindows and NI-XNET library

Hi all,
For my application, i would like to feed my LabWindows CVI Test program with data extracted from *.dbc file (created by another team under Vector CANdb++).
These files contains all CAN frame definition
and also some extra information added to :
Message level,
Signal level,
Network Level
These extra information are set by using specific ATTRIBUTE DEFINITIONS - FUNCTIONALITY under Vector CANdb++
The opening of the DataBase works under NI-XNET DataBase Editor as in LabWindows using: nxdbOpenDatabase ( ... )
No attribute seems be displayable under the NI-XNET DataBase Editor (it's not a problem for me)
Now, how, using the NI-XNET API and CVI, be able to extract these specially created attributes ?
Thanks in advance.
PS : In attached picture, a new attribute called Test_NI, connected to a message
Attachments:
EX1.jpg ‏36 KB

Hi Damien,
To answer your question on whether the XNET API on LabWindows/CVI allows you to gain access to the custom attributes in a DBC file, this is not a supported feature. The DBC format is proprietary from Vector. Also, custom attributes are different for all customers and manufacturers. Those two put together make it really difficult for NI to access them with an API that will be standard and reliable.
We do support common customer attributes for cyclic frames. This is from page 4-278 in the XNET Hardware and Software Manual :
"If you are using a CANdb (.dbc) database, this property is an optional attribute in the file. If NI-XNET finds an attribute named GenMsgSendType, that attribute is the default value of this property. If the GenMsgSendType attribute begins with cyclic, this property's default value is Cyclic Data; otherwise, it is Event Data. If the CANdb file does not use the GenMsgSendType attribute, this property uses a default value of Event Data, which you can change in your application. "
Link to the manual : http://digital.ni.com/manuals.nsf/websearch/32FCF9A42CFD324E8625760E00625940
Could you explain us the goal of this attribute, and what you need it on your application.
Thanks,

How to retrieve the values from a Transient View Object

Hi Experts,
I am using Jdevelpoer11.1.1.5.0. I created one Transient view object with attributes EmpId,Salary.
In Backing Bean i will create rows for that view object and display it in the form of <af:Table> like Empid, Salary and an Update Link.
Now my problem is i want to update the salary of the particular EmpId. For Example if the EmpId is 100 and salary is 10000 now i want to increase the salary to 20000 and if i click on the update button; i want to retrieve the particular employee details in my backing bean. How can i acheive this?
Thanks in advance.

A better approach would be to programmatically populate rows in the <VO>Impl.java by overriding the executeQueryForCollection(0 as specified here -
http://adfpractice-fedor.blogspot.in/2011/01/adf-bc-programmatically-populated-vo.html
You can write the logic to update the salary in an AM method then on click of Update or in the getter of Salry field if logic is valid for all fields...
