How to send results to actionscript using java
Hi,
I do RPC using HttpService.
In my situation, I need to send results from Java code to
Flex Action script. I have defined a Java Servlet receiving data
from Flex application, then it processes with the data, finally the
Servlet is supposed to send some feedbacks to the client(Flex).
My question is that how can I define codes in doPost() method
that the following function will get "result" from the Java side.
public static function httpResult(event:ResultEvent):void
var result:Object = event.result;
//Do something with the result.
if (result.toString() == "success")
resultMessage.text = "Login Success";
resultMessage.text = "Invalid User";
}Hi,
Try this: If you are sending a simple text as "sucess" or
"error" after doing some process in the servlet..
set your content type to "text/plain" and simply
println(<data to be sent>);
In the flex application, get the result text that the servlet
send using:
resultString = String(httpUrl.lastResult);
where httpUrl is the id of the HTTPService. Now you can
compare what the servlet send by:
if(resultString=="sucess") {
Hope this solves your problem :)

How to send results to actionscript using java via HttpService
Hi,
I do RPC using HttpService.
In my situation, I need to send results from Java code to
Flex Action script. I have defined a Java Servlet receiving data
from Flex application, then it processes with the data, finally the
Servlet is supposed to send some feedbacks to the client(Flex).
My question is that how can I define codes in doPost() method
that the following function will get "result" from the Java side.
public static function httpResult(event:ResultEvent):void
var result:Object = event.result;
//Do something with the result.
if (result.toString() == "success")
resultMessage.text = "Login Success";
resultMessage.text = "Invalid User";
}I advise having your servlet build an xml string, maybe put a
status attribute in the root tag, like this:
<myroot status="success">
<mytext>Some text</mytext>
</myroot>
and return that to the calling Flex client. XML is easier to
work with than Object. On the HTTPService tag, set
resultFormat="e4x", and it will return plain XML.
then in the handler, do:
var xmlResult:XML = XML(event.result); //this will already be
the myroot node
//Do something with the result.
if (xmlResult.@status== "success") //reads the status
attribute
resultMessage.text = xmlResult.mytext.text(); //get the
value of themytext text() node
resultMessage.text = "Error";

The answer is too easy and straightforward that I guess that you mean something else. If you just want to know how to configure an SSL environment for your own webapplication, refer to the Java EE tutorial chapter 28: http://java.sun.com/javaee/5/docs/tutorial/doc/ -

Hi,
How to read a string from a file and assign the value to a variable then return the value to the screen in windows batch file?
Any suggestions?
thanks.Unless this is a homework question then I don't see the purpose of doing this, but....
You should be looking a the supplied package utl_file to get the string out of the file, dbms_output to display the string and then google windows batch/command files calling sqlplus to execute your program.

How to search a string from the database?
how to search a string from the database? starting with some character
If you're trying to do this in a SELECT, you can use the LIKE verb in your WHERE clause.
Here's an Example
SELECT obj_name FROM tadir
INTO prog
WHERE pgmid = 'R3TR'
AND object = 'PROG'
AND obj_name LIKE 'Z%'.
In this case it will select every row that obj_name starts with Z.
If you wanted to find every row that the field obj_name contains say... 'WIN' you use LIKE '%WIN%'.

Hi,
I am sending an e-mail using java. It works fine, but I wanted to know if there is any possibility to attach a document, without using a File object. Because I have to write the File object and then delete it at the end. I would like to know if I can use for example a byte [], or something else.
Thank you very much.
This is my code, if that helps.
public static void sendWithAttach(String p_sender, String p_receiver, String p_subject,
String p_comment, int p_nombrePiecesJoints, HashMap<String, byte[]> p_files) {
Properties props = System.getProperties();
props.put("mail.smtp.host", Solapcore.getCurrent().getServletConfig().getServletContext().getInitParameter("SMTP"));
Session session = Session.getDefaultInstance(props, null);
MimeMessage sender = new MimeMessage(session);
MimeBodyPart mbp1 = new MimeBodyPart();
Multipart mp = new MimeMultipart();
List<File> listeFiles = new ArrayList<File>();
try {
//On assigne to, from, subject, body, priority
sender.setRecipients(javax.mail.Message.RecipientType.TO,
InternetAddress.parse(p_receiver, false));
sender.setFrom(new InternetAddress(p_sender));
sender.setSubject(p_subject);
mbp1.setText(p_comment);
//sender.setPriority(0);
mp.addBodyPart(mbp1);
//On attache les documents
for(Map.Entry<String, byte[]> entry : p_files.entrySet()) {
MimeBodyPart mbp2 = new MimeBodyPart();
String fileName = entry.getKey();
byte [] dataFile = entry.getValue();
File file = new File(fileName);
FileOutputStream fos = new FileOutputStream(file);
fos.write(dataFile);
mbp2.attachFile(file);
mbp2.setFileName(fileName);
mp.addBodyPart(mbp2);
listeFiles.add(file);
sender.setContent(mp);
Transport.send(sender);
}catch(MessagingException mex) {
mex.printStackTrace();
}catch(FileNotFoundException fnf) {
fnf.printStackTrace();
}catch(IOException ioe) {

}finally {
Iterator<File> itListeFiles = listeFiles.iterator();
while(itListeFiles.hasNext()) {
File tempFile = (File)itListeFiles.next();
tempFile.delete();
}Thank you very much.

How do i transfer music from one ipod to another using itunes
how do i transfer music from one ipod to another using itunes
Welcome to the Apple Community.
There is more than one way, but to get it all on all devices, connect the first device to iTunes and choose to transfer the music from the device from the file menu. Once everything is in iTunes connect the second device, select the device in the device list, navigate to the music tab and check the content you wish to sync, click apply/sync.
