Storing the variable

Hi,
How is it possible to store the amount of a bean property in to the variable that has been defined in jsp file using declaration tag (<%! %>)?
for example how is it possible to store the amount of 'b1.i' to 'k'
<%! int ik= 0; %>
<jsp:getProperty name="b1" property="i"></jsp:getProperty>

it is possible, but it is not recommended.
Variables declared in <%! %> tags are not thread-safe, and can cause issues.
but you would have to do it via java code, get the attribute, cast it to its type, and then call its method. Something like this:
Object obj = pageContext.findAttribute("b1");
BType b1 = (BType) b1;
ik = b1.getI();However I would recommend that you don't have any scriptlet code on your pages. Use JSTL, and any java operations that need to be done should be done in a javabean/servlet

How can I convert the variable expression stored as string back to variable expression

How can I convert the variable expression stored as string back to variable expression?
I am storing the expression enterd in the TSExpresssionEditControl as simple string and want to convert back to expression since I want to get the data type of that expression.

pritam,
I'm not sure what you're trying to do exactly. If you are trying to get the value of a variable and you only have the name of value in a string, then you can use Evaluate() to get its value. If you want the data type, my advise is to use the GetPropertyObject() API method and just pass in the loop up string. Then you'll have a handle to the data object and then proceed from there.

How to insert the data which is present in the variable into the table

Hi,
Let's consider that I have one table and I have stored the table column names in one variable and their values in another variable.
I want to insert the data that is present in the variables into the table.
I tried the following way :
Declare
V_columns    Varchar2(50) := 'Empno';
V_values       Number(10) := 101;
Begin
Insert Into Emp (V_columns) Values (V_values);
End;
The above procedure gives an error : PL?SQL : ORA-00904 : "V_COLUMNS": invalid identifier
Using the Execute Immediate, we can insert the data which is present in the variables into the table.
Is there any other way to insert the data which is present in the variable into the table..?
Can anyone please give me the solution..?
Thanks..

plz use this...
DECLARE
   v_columns   VARCHAR2 (50) := 'Empno';
   v_values    NUMBER (10)   := 101;
BEGIN
   EXECUTE IMMEDIATE    'Insert Into Emp ('
                     || v_columns
                     || ') Values ('
                     || v_values
                     || ')';
   COMMIT;
END;

How to get values from a stored package variable of type record ?

Sir,
In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
What is the best way to do that ?
Thanks
Stephen

Stephen,
not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.

How can i view the variables of the session memory

Hi experts
How can i view the variables of the session memory.Such as I want display the variables of memory which id is 'BULRN' in ABAP debug.
In program i can use import from memory id visit the momery of session,but i don't know the name of variables which store in momery of my session.

Its not possible to view in the debug mode..
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
SAP global memory retains field value through out session.
set parameter id 'MAT' field v_matnr.
get parameter id 'MAT' field v_matnr.
They are stored in table TPARA.
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
ABAP memory is temporary and values are retained in same LUW.
export itab to memory id 'TEST'.
import itab from memory Id 'TEST'.
Here itab should be declared of same type and length.

How to execute a select query stored in variable

Hello helpers ,
I have some "select queries" stored in the database . Now I can derive this query in some variable . How do I execute this query from the variable .
example :
Data Query type char50 .
QueryVar = 'Select MATNR from MBEW where BWKEY = '0001' . '
How do I execute this Query stoored in variable QueryVar in ABAP program ?
Thanks a lot for helping .
Regards
Shashank

Shashank,
It is also possible to use (column_syntax) and (dbtab_syntax) together with (cond_syntax) when using SELECT statements in ABAP. For more info on (column_syntax) and (dbtab_syntax) just have a quick look at ABAP Keyword documention on SELECT statement (hit F1 on SELECT then scroll down to Select->Select result->Select Columns....)
So in your case, you need to separate out (split) the value in 'wa_itab-query' into other variables or append into separate internal tables using common keys etc. - then looping at those tables with the common key (READ TABLE WITH KEY....) use the following syntax at the time of triggering the SELECT query:
SELECT (column_syntax)
       FROM (dbtab_syntax)
       WHERE (cond_syntax).
Also worth a look at this example below:
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
            p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
         fldate TYPE sflight-fldate,
         carrname TYPE scarr-carrname,
         connid   TYPE spfli-connid,
       END OF wa.
DATA itab LIKE SORTED TABLE OF wa
               WITH UNIQUE KEY fldate carrname connid.
DATA: column_syntax TYPE string,
      dbtab_syntax TYPE string.
column_syntax = `c~carrname p~connid f~fldate`.
dbtab_syntax = `( ( scarr AS c `
& ` INNER JOIN spfli AS p ON p~carrid = c~carrid`
& ` AND p~cityfrom = p_cityfr`
& ` AND p~cityto   = p_cityto )`
& ` INNER JOIN sflight AS f ON f~carrid = p~carrid `
& ` AND f~connid = p~connid )`.
SELECT (column_syntax)
       FROM (dbtab_syntax)
       INTO CORRESPONDING FIELDS OF TABLE itab.
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.
ENDLOOP.
Hope this helps.
Cheers,
Sougata.

Stored Procedure - variable name inside string [EXEC]

Hi everyone
I'm looking for a solution for this problem:
I've created a stored procedure, in which i need to insert a record in a table.
The point is i don't know the exact column to put my values and which values to save: it depends from the input data.
I've created a function wich creates (concats) my query.
The result is similar to:
SET @myquery = 'INSERT INTO MyTable (columnABC, columnDEF) VALUES (@valueABC, @valueDEF)'
This query is the value of a varchar.
I want to execute this query, so I thought to use: EXEC(@myquery)
The problem is that SQL can't find the variables @valueABC or @valueDEF if thery're inside a nvarchar.
Is there some particular syntax in order to replace the value of variables?
I hope it's clear!!
Thank you in advance!!!!!
Federica

You need to create an entire SQL string without the variables.
SET @myquery = 'INSERT INTO MyTable (columnABC, columnDEF) VALUES (''' + @valueABC + ''', ''' + @valueDEF + ''')'
Please, please don't post such bad solutions!
If you use dynamic SQL, you should use a parameterised statement:
SET @myquery = 'INSERT INTO MyTable (columnABC, columnDEF) VALUES (@valueABC, @valueDEF)'
EXEC sp_executesql @myquery, N'@valueABC int, @valueDEF int',
   @valueABC, @valueDEF
However, I would prefer not to use dynamic SQL at all, but do:
INSERT tbl(keycol, col1, col2, col3, ....)
   VALUES (@keyval,
   CASE @coltoinsert WHEN 'col1' THEN @val END,
   CASE @coltoinsert WHEN 'col2' THEN @val END,
Although the entire idea of not knowing the columns before sounds spooky to me. A column in a table is supposed to model a unique attribute.

Stored Procedure/Variable issue

Hopefully this is the last issue to work through... but we need to access images stored on another server. We have a stored procedure called 'get_doc' that accesses the image file, and we've successfully tested it with a hardcoded value. A button calls a process that executes the following PL/SQL:
get_doc (
p=> 77456);
However, when I use the same process with a variable on the page (which has the same numeric value of 77456), the procedure says the value of p is Null.
get_doc (
p=> :P7_STARTERNUM);
Any suggestions or advice?
(Using ApEx 4.0 in IE8)

CPate wrote:
Yes, the connection is correct. And I swapped in the hardcode number, the process does what it is supposed to and returns the image. Swap back in the variable (with to_number as well, just to be sure) and it returns null.
I tried debugging it and didn't see where P7_STARTERNUM was changed. It just says:
..Process "STARTERGET": PLSQL (AFTER_SUBMIT) get_doc (p=> to_number(:P7_STARTERNUM));The trace should look something like:
0.00275     0.00220     A C C E P T: Request="SAVE"

{code}
There should be a session state change like those shown recorded for your <tt>P7_STARTERNUM</tt> item.
What's the *Display As* type of the <tt>P7_STARTERNUM</tt> item?
the procedure says the value of p is Null.
How do you know this?

Listener Servlet storing session variables

hi all,
i have a listener servlet class which is performing tcp/ip socket communication. now i want this class to store session variables. i have tried to implement it and access the stored variable values from other pages, but i am unable to access them, which tells me that the servlet is not storing the values in the first place.
any help. thanks in advance.

can you post some code.
it is also posible that those values are stored in a different session that in the one you try to read from

Need advice on storing configuration variables for use by FP2000 Controller for embedded application.

I am creating 8 machines that generally operate in the same way and each will be controlled using a FP-2000 controller. The only difference between the machines is a set of scaling constants and pass values for determining if the machine completed its process successfully.
In the past, using an idependent PC and Labview, I have created a configuration.vi for writing the constants and configuration variables to a data file on my hard drive. Then in the auto.vi I read(only once each time the program is started) the file and store the data in the program. I would like to do something similar with this system but am not familar with the Field Point system.
I know i
t is probably not difficult to store the data to the host computer and transfer it to the modules but I am better off writing to the modules once and storing the data onboard the FP controller for use by an embedded application. This way, if the network connection is lost for any reason, the machine can still operate. Is this possible, and if not what do you suggest in order to prevent being so reliant on the host computer?
Thank you for your help.

Mike,
There are a number of ways to accomplish what you desire. The easiest is to continue doing what you are already doing. The FP-20xx series modules treat their flash memory as if it was a hard drive, so the file I/O VI's in LabVIEW work just the same in a FP-20xx as on a regular computer running LabVIEW. The primary variation will be in how you write the files over the network. Since mapping network drives is more of a Windows functionality, you can not simply have a VI running on your host computer use a File I/O VI to write to a FP-20xx. Instead, what you will need to do is to write the file to you local drive and then FTP (file transfer protocol) the VI to the FP-20xx module. This can be done using the LabVIEW Internet toolkit or any 3rd party FTP util
ity. One word of advice; the OS on the FP-20xx does not support long filenames but due to a problem in the FTP server, long filenames (non 8.3 compliant) may be uploaded and once there, you will be unable to access the file again, even to delete it.
An alternative method that I have seen used is to use a global VI and write to it from the host machine through the use of VI server. You can then have the program on-board the FP-20xx save the globals to your configuration file.

Aaron

Storing a variable for use in another class.

Hello All,
I am trying to develop a database front end and I came across a problem which I've spent 2 days trying to figure out.
I have a main jFrame(MainUI) which just has 2 menu items Add a client(class called Clients) and Manage Clients (class called ManageClients).
When a user selects Add a client it opens up the Clients frame and the user can save Client information to the database.
When a user selects Manage Clients it opens up the ManageClients frame which displays all the clients from the database in a jTable.
When the user clicks a row from the jTable I store the ClientID which is in column 1 in the jTable into a variable.
The user can then click on a jButton called EditClient within the ManageClients frame.
When the user does this I want to be able to Close the ManageClients frame and open the Clients frame so the user can edit the client information.
I just need to figure out how to pass the variable ClientID to the Clients frame so I can execute a query to display the client information.
First I tried creating a class ClientID..
Code:
package pms;
public class ClientID {
    private int clientID;
public ClientID(){
public ClientID(int clientID){
    this.clientID = clientID;
public int getID(){
    return clientID;
public void setID(int clientID){
    this.clientID = clientID;
} Then I tried storing the ClientID from the ManageClients Class...
Code:
private void btnEditActionPerformed(java.awt.event.ActionEvent evt) {
        ClientID clientid = new ClientID();
        clientid.setID(50);
        /**Close the ManageClients frame*/
        this.dispose();
    } When I try to do a test to get the Client ID it returns 0..
I just put a jButton on the Main form to do a test to get the ClientID and change the jButton text to the ClientID.
Code:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        ClientID clientid = new ClientID();
        String theid = Integer.toString(clientid.getID());
        jButton1.setText(theid);
    } I think whats happening is Im creating a new instance of ClientID.
any suggestions to get this to work?
Thank you.

Ok so here is what I have tried to understand.
Class MainUI:
private ClientID clientID;
public void setclient(ClientID ID){
        this.clientID = ID;
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        int theid = clientID.getID();
        jButton1.setText(Integer.toString(theid));
    }     Class ManageClients:
private void btnEditActionPerformed(java.awt.event.ActionEvent evt) {
        ClientID clientid = new ClientID();
        clientid.setID(50);
        MainUI main = new MainUI();
        main.setclient(clientid);
        this.dispose();
   }          getting a NullPointerException
hmmm.. I suck

I am having macbook air recently my iphotos did not open and was showing report apple and reopen but i came to know that by pressing alt and iphotos i open an new photo library and stored the pics but now how can i get the pics which i had in the earlier

i am having macbook air recently my iphotos did not open and was showing report apple and reopen but i came to know that by pressing alt and iphotos i open an new photo library and stored the pics but now how can i get the pics which i had in the earlier photo please help me to recover my photos

Well I'll guess you're using iPhoto 11:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Getting error while creating the variable of Schema Element type

Hi everybody,
For creating a variable of schema element type I am doing the following steps...
Select 'Variables' after right clicking on bpel process. IN this window, go to 'Create VAriable' then select 'Element' type. Now in Type Choose, I expanded the my imported schema files. And selected a element type, then click ok to create this variable... I am getting the message...
IN ORDER TO SAVE IMPORTED WSDL/SCHEMA FILES, YOU MUST HAVE A PARTNER LINK LOCATED UNDER THE CURRENT PROJECT DIRECTORY.
What is mean by that.
I have imported the schema files in project. AFter that I have imported them into the WSDL also. Now why I am getting error while creating the variable. However I can create variable directly in .BPEL file then everything is fine. And it is working also. But what is mean with the above error? Why I am not able to create variable through GUI?
Thanks.

Hi,
I have this same problem this morning, and I was going crazy, until I found this webpage on the internet:
[http://technology.amis.nl/blog/1803/problem-importing-xml-schema-in-bpel-process|http://technology.amis.nl/blog/1803/problem-importing-xml-schema-in-bpel-process]
The idea is that the jdeveloper is not very good working with directories with spaces on the directory name. If you move all your work to a directory without spaces, it will work smoothly. At least, it had worked for me.
