Pass a variable name to a subroutine and use a method on it...

How do I pass a variable name to a subroutine and then call a method on it?
I have several swing text fields in a JForm. When someone enters a string in any of these fields, I want to check whether it is a number and, if now, clear that individual field and display a popup warning.
So, I want to do something like....
String stringcheck(String str, sometype variablename) {
        try {
            Integer.parseInt(str);
        } catch (NumberFormatException e) {
            JOptionPane.showMessageDialog(jPanel2, "These fields must be integer numbers.");
            variablename.setText("");
}

Well, good to hear you found a solution to it.You know, you really should have seen that from post 1.
No offense, but seriously - does he have to draw you a picture?!
I probably wouldn't understand the picture either: I'm not much of an art critic. Unless the OP is [Bob Ross|http://www.bobross.com/], his paintings, I understand.

sorry....i tested with cp command it was working fine...
so, i thought it should work for exp command also.
but its not working....also its not throwing any error....
the crontab -e is having...
00 02 * * * exp userid=system/password@realdb file=/u02/test/n22.dmp log=/u02/test/n22.log owner=scott statistics=none
also i have tested by calling the script.
#!/bin/bash
00 02 * * * /u03/script/testbkp.sh
its not working
but the below one is working....
00 02 * * * cp /u02/test.txt /u02/test/test.txt
also this one is working....
#!/bin/bash
00 02 * * * /u03/script/testbkp.sh
i listed the chkconfig --list crond
crond 0,1,6 = off
2,3,4,5 are on
what might be the reason?

Need a fast answer... passing javascript variable to jsp page (how to use)

This test application has 3 frames.
I'm assigning a value "stuff" to a variable ("testfield1") in a javascript function ("getTest") that exists inside an html frame (testpage1.html)
Then, I click on the "test submit" hypertext link to pass the value of "testfield1" to the JSP frame (testpage2.jsp) by invoking a function ("getData") in "testpage2".
In function ("getData"), I am passing the variable "testfield1" as a parameter to the "getData" function in "testpage2".
In "testpage2" - in the ("getData" function) I try to assign the value of the variable "testfield1" to another variable called "testfld1".
Then, I try to extract the value of "testfld1" into a variable called "tstfld1" in a JSP scriptlet
....I.E. [ String tstfld1 = request.getParameter("testfld1"); ]
But, the value is apparently not passed successfully, as tstfield1 appears to be "null".
Can anyone explain what I'm doing incorrectly?
The code for this test app is below...

parent.frames[2].getData(testfield1); is in testpage1.html
so in the document.pageData.testfld1.value = testfield1; document = testpage1.html( not testpage2.html)
modifying the getData to accept the document object, and refering this object to parent.frames[2].document may help you.
good Luck ....

Javascript enabling and using JS methods on TextEdit component

Hello Friends:
I am working to display data using TableView component.
In each row, one of the cell contains a group of radio
buttons and an other cell contains TextEdit component.
For an event on the group of radio buttons, the TextEdit
should flip editable to non-editable and vice-versa.
I am using the TextEdit attribute method,
<b>setJsObjectNeeded(true)</b>
to expose the JavaScript methods of the component.
I am using the following bits of code for accessing the
TextEdit JavaScript functionality.
var funcName = htmlb_formid+"_getHtmlbElementId";
func = window[funcName];
var text_edit_comp = eval(func(id_of_textedit));
<b>text_edit_comp.setEnabled()</b>;
Whole thing works as planned, but it is not possible to
disable or enable the TextEdit component using the
JavaScript, as shown above.
In the portal documentation, the JavaScript object
methods were mentioned only for certain components, NOT
including TextEdit !!
If I replace TextEdit with InputField, it works perfectly
as like needed.
How to hack it to work for TextEdit ?
Thank you very much for your kind answers.
Prasad Nutalapati

I did use the suggestion. No use.
When I say,
var textedit = eval(func("<id-of-the-textedit-from-java"));
I am getting the object reference.
When I say,
<b>var id = textedit.id;
var elem = document.getElementById(id);</b>
I am getting the HTML name/id and object of the text edit.
Now when I use JS methods and properties,
alert("type="+elem.type);
alert("name="+elem.name);
I get them back correctly.
Then when I say,
<b>alert("disable ?"+ document.forms[0].elements[elem.name].disabled;</b>
I am getting answer as 'false' which is not correct. It
is initially disabled, when I defined with Java.
And subsequently, when I say,
<b>document.forms[0].elements[elem.name].disabled = false;</b>
It didn't affect it at all.
If I try to use the JS methods provided by Portal, like..
<b>textedit.setEnabled();</b>
It is giving an JS error saying that the object doesn't
have that method.

Can we pass IT table name dynamically to READ and SORT stmt

Hello All,
i have a requirement in which i am passing table name using a variable and want to read the same table: so my question is can we execute read and sort stmt with dynamic IT name. please see below for explaination.
v_itname = <it_2>.
now read using variable
READ table ( v_itname ) with key <field>.
and
SORT ( v_itname ) by (otab).
thanks
Mani

Hi ,
This can be done. Please refer to the codes below. Please note that the code will work if the itabs are of type standard table else it may dump.
You just need to replace the variables form the values from your internal table.
DATA: v_table1(10) TYPE c VALUE 'I_MARA',
      v_field(10) TYPE c VALUE 'MATNR',
      i_mara TYPE STANDARD TABLE OF mara.
FIELD-SYMBOLS : <fs_tab>   TYPE STANDARD TABLE,
                <fs_field> TYPE ANY.
DATA: otab TYPE abap_sortorder_tab,
oline TYPE abap_sortorder.
SELECT * UP TO 10 ROWS
FROM mara
INTO TABLE i_mara.
IF sy-subrc = 0.
ASSIGN (v_table1) TO <fs_tab>.
IF sy-subrc = 0.
    oline-name = v_field.
    APPEND oline TO otab.
    SORT <fs_tab> BY (otab).
    READ TABLE <fs_tab>
    WITH KEY (v_field) = '000000000020000989' "
    BINARY SEARCH
    TRANSPORTING NO FIELDS.
    IF sy-subrc = 0.
    ENDIF.
ENDIF.
ENDIF.

:-)Well ... we had that once before ... she was offended .. kinda .... Don't know about Saadia ... so far she's looking for a solution I guess, once she has that .. than she'll think about "other" things! :-)
But to answer your question, you can use he/she. Is that too much extra typing? I guess, the posters also can add a (Mr./Miss) to their names ... if they care ... actually that's what I suggested this other lady to do! :-)

Upload Component, Pass extra Variable

Hello all.
I have been trying to get an upload component to work for some time now, but have been having a few troubles getting one to do what i need. Recently i found a component that does pretty much everything i want bar one thing, pass an extra variable to the PHP script so i can name the files something unique.
My Flex code is -

                var fileList:Array = fileReferenceList.fileList;
                // get the first file that the user chose
                fileReference = FileReference(fileList[0]);
                // upload the file to the server side script
                fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
                fileReference.upload(urlRequest);
                // update the status text

While my PHP code it
<?php

$fileSize = $_FILES['Filedata']['size'];
$id = $_POST["id"]
$newName = '$id'.'.doc';
move_uploaded_file($tempFile, "./" . $newName);
?>
What i am trying to do is, when the user clicks the "Upload File" button on the flex app, after they pick a file, it currently uploads that file using the name of the given file. But what i want to do, is to pass the variable "ID" to the PHP and use that as the file name instead.
Im a little bit stumped as to how to do this ? I dont know where to include the code to pass "ID", normally i deal with HTTPSservice's where you declare such things in the function.
Any help would be great.!

You should be able to add a parameter using URLVariables, so change your init function to something like:
            private function init():void {
                urlRequest = new URLRequest(serverSideScript);
                var variables:URLVariables = new URLVariables();
                variables.myFileName = "flexponential";
                urlRequest.data = variables;
                fileReferenceList = new FileReferenceList();
                fileReferenceList.addEventListener(Event.SELECT, fileSelectedHandler);
And then in your PHP file you should be able to access that data via the post variable.
$myFileName = $_POST["myFileName"];

Child.swf to pass two variables to parent in global function

Hi, I have a parent.swf and wish to load a varying child.swf as a sub-menu. How do I establish a global function that will allow the child.swf to pass back two variables (storyName & storyType) to the parent and kick off a task.
The submenu (swf) items will change so I cannot explicitly add a listener to a child.button. The submenu is on a children’s library so will have numerous graphics and movieclips included so I don’t think it would be suitable to simply call xml data to build a menu at runtime (at my level of knowledge). There will be a number of child.swf depending on books available.
I am not familiar with package { and public class { etc...
In as2 I would have used a _global.function() and used that to pass the variables back to the parent and then start a parent.action.
Totally new to AS3, suggestions appreciated. I have no problem loading the child.swf.

Hi Ned, thank you for your response. I don’t know if it is relevant, but the container clip is run via AIR. That seems to affect some things as I’ve lost fullscreen functionality somewhere.
I tried you suggestions, if I have translated it into place correctly I don’t know. Do I need to treat the parent.parent as a variable (yes this one is done via a loader) ?
I get an error if I leave the function call open, I can tell I’m getting into the call as the trace on each side is happening.
In the External Movie:
blob_b.addEventListener(MouseEvent.CLICK, ms_bF);
function MbRemEL(nameof:String):void {
            blob_b.removeEventListener(MouseEvent.CLICK, ms_bF);
function ms_bF(event:MouseEvent):void {
            var m_ar:Array = new Array();
            m_ar=event.target.name.split("_");
            MbRemEL("r");
            trace("StoryMenu: "+event.target.name);
            if (this.parent.parent != null){
                        MovieClip(parent.parent).story = event.target.name;
                        //MovieClip(parent.parent).gcr(event.target.name);
                         // = TypeError: Error #1006: gcr is not a function.
                        MovieClip(parent.parent).gotoAndStop("g_home");

How to pass local variables between different sequence files?

Actually i want to pass the data (local variable) from my process model file to a client file. The client file only has the callbacks and those callbacks require some parameters as input which is available in local variables of my process model sequence file. I do not want to use Station Globals.
Please tell me any other way by which i can pass that data.

Which Locals do you want from the model. Every sequence has it's own Locals and there are a bunch of sequences in every process model. Do you want the entry point's Locals? A callback's Locals? Just one of the sequence's Locals? Some Models have way more entry points than others. What if your sequence file is ran with a different entry point?
One option is to create your own callback in the model and pass the data to it as parameters. Then add that callback to your client sequence file and get it out of the parameters.
If you simply want the entry point's locals and you are in your Main Sequence then you could use RunState.Caller.Locals.VariableName. This assumes you will use the same entry point every time you run that sequence file. Or assumes that every entry point you run has the same Local variable name.
Maybe there is an API method that exposes what you are looking for. What is your goal?

Passing javascript variable to java bean

Hi all,
Is there any way to pass a java script variable to a java bean. i'm trying hard but in vain. please suggest a way how to do it...

The variable u want to pass declare that in a dataobject class i.e consisting of getter and setters ...... when you will use the jsp:useBean tab and the setProperty tag along with the class name it will set the value of the variables ...... use form method = get to set the variables.

Same variable name causes major issues.....

I would like to get some input and possible direction on the issue below... I am new to PL/SQL. Thanks in advance.....
..... The system is in the middle of processing a “For” step, i.e. a given “For” step is incomplete.
..... The script instructs the system to process a second “For” step with the same “for-loop variable” as the incomplete “For” step.
When the above takes place, the system processes the second “For” step incorrectly. Instead of starting at the first value in the second “For” step’s list of values, the system begins in the middle of the value list.
I need to change the current implementation so that if a "For" loop is encountered that has the same “loop variable” as a “For” loop already being executed, the “state” of the previous “For” step is discarded, and the state for the new “For” step is initialized to the first value in its list.
-- Used for "for" steps
TYPE for_list is table of varchar2(4000) index by binary_integer;
TYPE for_loop_state is record (
list for_list,
next_index integer
TYPE for_loops_list is table of for_loop_state index by steps.output_param%TYPE;
all_for_loops for_loops_list;
procedure for_step(list_string IN varchar2, ret_var_name IN varchar2, end_for_label IN varchar2) is
state for_loop_state;
end_idx number;
list_value varchar2(4000);
begin
pkg_util.log('ret_var_name value after begin: ' || ret_var_name, 'I');
-- get the current for list state, based on its output variable name
if all_for_loops.exists(ret_var_name) then
state := all_for_loops(ret_var_name);
else
state.next_index := 0;
list_value := parse_next_param(list_string, 1, end_idx);
-- end_idx is thrown away; for loops only have 1 input parameter (the list)
state.list := get_for_list(list_value);
all_for_loops(ret_var_name) := state;
end if;
if state.next_index < state.list.count then
pkg_session_values.put(ret_var_name, state.list(state.next_index));
all_for_loops(ret_var_name).next_index := state.next_index + 1;
else
all_for_loops.delete(ret_var_name);
jump(end_for_label);
end if;
end;

There is so much of your code hidden from view it is impossible to tell you anything other than perhaps suggest a methodology.
Create a single variable with a known value and use dbms_output to view it as it steps through each piece of the puzzle. Determine when the value does something you don't want.

Passing Inner class name as parameter

Hi,
How i can pass inner class name as parameter which is used to create object of inner class in the receiving method (class.formane(className))
Hope somebody can help me.
Thanks in advance.
Prem

No, because an inner class can never have a constructor that doesn't take any arguments.
Without going through reflection, you always need an instance of the outer class to instantiate the inner class. Internally this instance is passed as a parameter to the inner class's constructor. So to create an instance of an inner class through reflection you need to get the appropriate constructor and call its newInstance method. Here's a complete example:import java.lang.reflect.Constructor;
class Outer {
    class Inner {
    public static void main(String[] args) throws Exception{
        Class c = Class.forName("Outer$Inner");
        Constructor cnstrctr = c.getDeclaredConstructor(new Class[] {Outer.class});

Error while using the variable name "VARIABLE" in variable substitution

Hi Experts,
I am using variable substitution to have my output filename set as a payload field value. It is working fine when I am using the variable name as fname, subs etc but channel goes in error when I am using the variable name as "VARIABLE". This is probably a reserved word but i would like to know where i can find a detailed documentation on this. Say things to note / restrictions while using variable substitution.
This is the error in the channel:
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error during variable substitution: java.text.ParseException: Variable 'variable' not found in variable substitution table: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: java.text.ParseException: Variable 'variable' not found in variable substitution table
Thanks,
Diya

Hi Zevik,
Thanks for the reply. The output file is created correctly by merely changing the variable name to something else and hence the doubt.
Below is the configuration:
Variable Substituition
VARIABLE payload:interface_dummy,1,Recordset,1,Header,1,field1,1
Filename schema : TEST_%VARIABLE%.txt
Output xml structure:
<?xml version="1.0" encoding="utf-8" ?>
- <ns:interface_dummy xmlns:ns="http://training.eu.unilever.com">
- <ns:Recordset xmlns:ns="http://training.eu.unilever.com">
- <Header>
<identifier>HDR</identifier>
<field1>001</field1>
<field2>001</field2>
<field3>R</field3>
</Header>
- <Detail>
<identifier>A</identifier>
<field1>000000002</field1>
<field2 />
<field3>Doretha.Walker</field3>
</Detail>
I thimk my configuration is correct as it is working correctly with the variable name change, However, maybe i missed something !

Pass a variable name to a subroutine and use a method on it...
