Executing unix script within java and getting the return value
Hi
I am executing a unix script from within java which will return me a value. Is there a way I get this value and use it inside my java code without doing this:
BufferedReader in = new BufferedReader( new InputStreamReader( ls_proc.getInputStream() ));
//readLine reads in one line of text
int k = 1, i = 0;
while (( ls_str = in.readLine()) != null)
--kirk123
I was hoping to get what I want in one or two line codes.

How to call an Oracle Procedure and get a return value in Php
Hi Everyone,
Has anyone tried calling an Oracle procedure from Php using the ora functions and getting the return value ? I need to use the ora funtions (no oci)because of compatibility and oracle 7.x as the database.
The reason why I post this here is because the ora_exec funtion is returning FALSE but the error code displayes is good. Is this a bug in the ora_exec funtion ?
My code after the connection call is as follows:
$cur = ora_open($this->conn);
ora_commitoff($this->conn);
$requestid = '144937';
echo $requestid;
$rc = ora_parse($cur, "begin p_ins_gsdata2
(:requestid, :returnval); end;");
if ($rc == true) {
echo " Parse was successful ";
$rc2 = ora_bind ($cur, "requestid", ":requestid", 32, 1);
if ($rc2 == true) echo " Requestid Bind Successful ";
$rc3 = ora_bind ($cur, "returnval", ":returnval", 32, 2);
if ($rc3 == true) echo " Returnval Bind Successful ";
$returnval = "0";
$rc4 = ora_exec($cur);
echo " Result = ".$returnval." ";
if ($rc4 == false) {
echo " Exec Returned FALSE ";
echo " Error = ".ora_error($cur);
echo " ";
echo "ErrorCode = ".ora_errorcode($cur);
echo "Error Executing";
ora_close ($cur);
The Oracle procedure has a select count from a table and it returns the number of records in that table. It's defined as:
CREATE OR REPLACE procedure p_ins_gsdata2 (
p_requestid IN varchar2 default null,
p_retcode OUT varchar2)
as
BEGIN
SELECT COUNT (*) INTO p_retcode
FROM S_GSMRY_DATA_SURVEY
WHERE request_id = p_requestid ;
COMMIT;
RETURN;
END;
Nothing much there. I want to do an insert into a table,
from the procedure later, but I figured that I start with a select count since it's simpler.
When I ran the Php code, I get the following:
144937
Parse was successful
Requestid Bind Successful
Returnval Bind Successful
Result = 0
Exec Returned FALSE
Error = ORA-00000: normal, successful completion -- while
processing OCI function OBNDRA
ErrorCode = 0
Error Executing
I listed the messages on separate lines for clarity. I don't understand why it parses and binds o.k. but the exec returns false.
Thanks again in advance for your help. Have a great day.
Regards,
Rudiretcode=`echo $?`is a bit convoluted. Just use:
retcode=$?I see no EOF line terminating your input. Your flavour of Unix might not like that - it might ignore the command, though I'd be surprised (AIX doesn't).
replace the EXEC line with :
select 'hello' from dual;
and see if you get some output - then you know if sqlplus commands are being called from your script. You didn't mentioned whether you see the banner for sqlplus. Copy/paste the output that you get, it will give us much more of an idea. -
How execute Unix script from java?
Can I execute Unix script from java?
Yes. Using ProcessBuilder. And read [When Runtime.exec() wont|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]. It's old, but pretty much all of it is still true.

Remote Object - not able to get the returned value from java method
Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">

And I have configured destination in remote-config.xml
<destination id="sro">

Please help me .You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
<Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert. -
Get the return value of an RFC function / BAPI
Hello,
I'm a Web Dynpro Java beginner and I try to get the return value (domain: NUMC6) of an RFC function without success.
Here is what I do, could you please tell me what is wrong?
First, here is my context:
Context
|
|---- ZMy_Bapi
|
|---- MyOutputResult
| |
| |---- MyReturnValue
|
|---- MyInput
My model:
MyModel
|
|---- ZMy_Bapi_Input
|
|---- Output
| |
| |---- ZMy_Bapi_Output
| |
| |---- Return_Value
|
|---- Input_Value
The mapping between them:
- MyInput is mapped to Input_Value
- MyReturnValue is mapped to Return_Value
And my code:
ZMy_Bapi_Input bapiInput = new ZMy_Bapi_Input();
wdContext.nodeZMy_Bapi().bind(bapiInput);
bapiInput.setInput_Value("A value");
executeZMy_Bapi();
ZMy_Bapi_Output bapiOutput = new ZMy_Bapi_Output();
wdContext.nodeMyOutputResult().bind(bapiOutput);
IMyOutputResultElement outputElement = wdContext.nodeMyOutputResult().currentMyOutputResultElement();
String result = outputElement.getMyReturnValue();
Finally, here is the code of the executeZMy_Bapi() function:
try {
wdContext.currentZMy_BapiElement().modelObject().execute();
wdContext.nodeMyOutputResult().invalidate();
} catch (Exception ex) {
ex.printStackTrace();
My problem is that "result" keeps being empty
Thanks in advance for your help!It still doesn't work, I'm gonna turn crazy!
But there is one good point: I get the method you mentioned: getZMy_Bapi_OutputElementAt and getMyReturnValue without casting, just as you said first.
Here are the updated context, model, mapping and code.
Context:
MyContext
|
|---- ZMy_Bapi
|
|---- MyOutputResult
| |
| |---- ZMy_Bapi_Output
| |
| |---- MyReturnValue
|
|---- MyInput
Model:
MyModel
|
|---- ZMy_Bapi_Input
| |
| |---- Output
| | |
| | |---- ZMy_Bapi_Output
| | |
| | |---- Return_Value
| |
| |---- Input_Value
|
|
|---- ZMy_Bapi_Output
|
|---- Return_Value
Mapping
ZMy_Bapi --> ZMy_Bapi_Input
MyOutputResult --> Output
ZMy_Bapi_Output --> ZMy_Bapi_Output
MyReturnValue --> Return_Value
MyInput --> Input_Value
Code
ZMy_Bapi_Input bapiInput = new ZMy_Bapi_Input();
wdContext.nodeZMy_Bapi().bind(bapiInput);
bapiInput.setInput_Value("A value");
executeZMy_Bapi();
ZMy_Bapi_Output bapiOutput = new ZMy_Bapi_Output();
wdContext.nodeMyOutputResult().bind(bapiOutput);
String result = "";
for (int i = 0; i < wdContext.nodeZMy_Bapi_Output().size(); i++) {
IZMy_Bapi_OutputElement resultElem = wdContext.nodeZMy_Bapi_Output().getZMy_Bapi_OutputElementAt(i);
if (resultElem.getMyReturnValue() != "" && resultElem.getMyReturnValue() != null) {
result = resultElem.getMyReturnValue();

Call C# method from javascript in WebView and retrieve the return value
The issue I am facing is the following :
I want to call a C# method from the javascript in my WebView and get the result of this call in my javascript.
In an WPF Desktop application, it would not be an issue because a WebBrowser
(the equivalent of a webView) has a property ObjectForScripting to which we can assign a C# object containg the methods we want to call from the javascript.
In an Windows Store Application, it is slightly different because the WebView
only contains an event ScriptNotify to which we can subscribe like in the example below :
void MainPage_Loaded(object sender, RoutedEventArgs e)
this.webView.ScriptNotify += webView_ScriptNotify;
When the event ScriptNotify is raised by calling window.external.notify(parameter), the method webView_ScriptNotify is called with the parameter sent by the javascript :
function CallCSharp() {
var returnValue;
window.external.notify(parameter);
return returnValue;
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = DoSomerthing(parameter);
The issue is that the javascript only raise the event and doesn't wait for a return value or even for the end of the execution of webView_ScriptNotify().
A solution to this issue would be call a javascript function from the webView_ScriptNotify() to store the return value in a variable in the javascript and retrieve it after.
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = ReturnResult();
await this.webView.InvokeScriptAsync("CSharpCallResult", new string[] { result });
var result;
function CallCSharp() {
window.external.notify(parameter);
return result;
function CSharpCallResult(parameter){
result = parameter;
However this does not work correctly because the call to the CSharpResult function from the C# happens after the javascript has finished to execute the CallCSharp function. Indeed the
window.external.notify does not wait for the C# to finish to execute.
Do you have any solution to solve this issue ? It is quite strange that in a Window Store App it is not possible to get the return value of a call to a C# method from the javascript whereas it is not an issue in a WPF application.I am not very familiar with the completion pattern and I could not find many things about it on Google, what is the principle? Unfortunately your solution of splitting my JS function does not work in my case. In my example my CallCSharp
function is called by another function which provides the parameter and needs the return value to directly use it. This function which called
CallCSharp will always execute before an InvokeScriptAsync call a second function. Furthermore, the content of my WebView is used in a cross platforms context so actually my
CallCSharp function more look like the code below.
function CallCSharp() {
if (isAndroid()) {
//mechanism to call C# method from js in Android
//return the result of call to C# method
} else if (isWindowsStoreApp()) {
window.external.notify(parameter);
// should return the result of call to C# method
} else {
In android, the mechanism in the webView allows to return the value of the call to a C# method, in a WPF application also. But I can't figure why for a Windows Store App we don't have this possibility. -
LiveCycle DS , can't get the return value of fill( arg) from Assembler class
Hi all!
I'm a have small problem , can any one help me? Please
I make a project which very similar to Product project(in
example).
1) Have Assembler class: I work correctly
package flex.samples.stock;
import java.util.List;
import java.util.Collection;
import java.util.Map;
import flex.data.DataSyncException;
import flex.data.assemblers.AbstractAssembler;
public class StockAssembler extends AbstractAssembler {
public Collection fill(List fillArgs) {
StockService service = new StockService();
System.out.print(fillArgs.size());
return service.getStocks();
public Object getItem(Map identity) {
StockService service = new StockService();
return service.getStock(((Integer)
identity.get("StockId")).intValue());
public void createItem(Object item) {
StockService service = new StockService();
service.create((Stock) item);
public void updateItem(Object newVersion, Object
prevVersion, List changes) {
StockService service = new StockService();
boolean success = service.update((Stock) newVersion);
if (!success) {
int stockId = ((Stock) newVersion).getStockId();
throw new DataSyncException(service.getStock(stockId),
changes);
public void deleteItem(Object item) {
StockService service = new StockService();
boolean success = service.delete((Stock) item);
if (!success) {
int stockId = ((Stock) item).getStockId();
throw new DataSyncException(service.getStock(stockId),
null);
some require class is ok.
2) I configure in data-management-config.xml
<destination id="stockinventory">
<adapter ref="java-dao" />
<properties>
<source>flex.samples.stock.StockAssembler</source>
<scope>application</scope>
<metadata>
<identity property="StockId"/>
</metadata>

<throttle-inbound policy="ERROR" max-frequency="500"/>
<throttle-outbound policy="REPLACE"
max-frequency="500"/>
</network>
</properties>
</destination>
3) My client app:
I use :
<mx:ArrayCollection id="stocks"/>
<mx:DataService id="ds" destination="stockinventory"/>
ds.fill(stocks); --> Problem here
When I run this app, The StockAssembler on the server work
correctly (i use printout to debug) . But variable stocks can't get
the return value,it is a empty list.
Please help me!Hi,
The executeQueryAsync method is “asynchronous, which means that the code will continue to be executed without waiting for the server to
respond”.
From the error message “The collection has not been initialized”, which suggests that the object in use hadn’t been initialized after the execution of the executeQueryAsync method.
I suggest you debug the code in browser to see which line of code will throw this error, then you can reorganize the logic of the code to avoid using the uninitialized object.

How to get the return values from a web page
Hi all :
how to get the return values from a web page ? I mean how pass values betwen webflow and web page ?

Edited by: jingying Sony on Apr 15, 2010 6:18 AMHi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

How to set the value of an LOV in CO prgramatically and get the Pkey value?
Hi,
I need to set a value to a LOV, say ItemLOV in a page through CO and get the Primaykey that LOV will return. How can I achieve this?
Req:
1. Set the Item_Name, say 'DELL_1618' so that the page displays this in the LOV.
2. Fetch the PK value returned by LOV in the backend into a VO attribute say Item_ID, '100009881'.
Thanks,
Santosh.Hi Santosh,
Sorry, I replied for General LOV Scenario, but want to set it programatically right,
You need to execute your LOV query in Controller for Item 'DELL_1618' using prepared statement, get the value for both dispaly value and Id and set it to LOV and FormVlaue Item in PR of controller.

How to sample an analog signal, simulated on labview and get the sample values.
My project involves this particular detail where i have to sample a simulated sine wave and get the samples and compare them so as to select a particular length for hanning window.Then it also requires me to experiment with the window size so as to get more efficient data out of the sampled signals. please help me with the sampling part and guide me as to how to perform a hanning window operation on the sampled signal. I have directly used the spectral analysis tool which involves getting a FFT spectrum by a default hanning window setting. But since i have to experiment with the window size and variations, guide me with the sampling part and applying a separate hanning window. Thank you.
