Need help : how to send 3 parameters over http using Java POST

I am trying to sending some data to agency company over http using Java POST
They need 3 parameters and some contents like below
1. Cmd : cmd=_RequestInsertNewLead
2 Live : False
3 XMLData : 3C%3Fxml+version%3D%........
I already have XML done ,but I don't know how to send these guy over http
is that like
this.out = new DataOutputStream(os);
out.writeBytes("Cmd");
out.writeBytes(" cmd=_RequestInsertNewLead");
out.writeBytes(" Live ");
out.writeBytes("False");
anyone could give help :)

First of all, are you getting any exception?
You didn't put much logging information in your code.
You can also try this.Instead of doing sos.println(".....") try to build the output string using string buffer.
Like:
StringBuffer sb = new StringBuffer();
sb.append("Some output");
sb.append("More output");
sos.print(sb.toString());
sos.flush();Let me know if this works.

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";

How applet transfers data over HTTP

hello,
I found out that you cannot you sockets in applets (cannot create a socken on the client side) so I want to know how to transfer data over HTTP. What class should I use or some short example would be of much help.

You can make connections back to the same server the applet came from. If you need to make connections directly to other servers, then you can sign the applet, which will lift the security restrictions (provided users accept your signature as trustworthy).

Need help in modifying mapping parameters of out the box mapping

Hi There,
I am a new bee to dac.
Need help in modifying mapping parameters of out the box mapping, which is invoked by DAC task.
We got a requirement to edit mapping parameter. When I go and see parameter under mappings tab in a mapping, I could not see any values in it.
But when I set any value, and validate it. It is successful.
Is it right way to do it?
What my concern is, When I initially go and see parameter values under maapings tab in a mapping, they are blank.
Where is it storing these values?
Thanks,
Rag

If you modify mapping then u have to create new task in dac and dac itself craete parameter file at run time. if you want to add more parameters then do it in dac system parameters tab.
Thanks
Jay.

If the third link you posted (the link containing the word "majority") does not look like the following then you inadvertently installed adware.
That particular page should resemble the following:
The word "majority" in the third paragraph should not be a link and should not have the green icon associated with it.
To learn how this may have occurred, and how to prevent it from occurring in the future, read How to install adware
Most so-called "news" websites are nothing more than entertainment outlets that cater to prurient interests, and contain advertisements that leave the user about three clicks away from installing junk. If you decide to frequent those websites, Safari's "Reader" feature helps minimize that exposure.

Hi,
a Windows Domain Controller does not have any local user or groups. So you might add the user to the admin group at Domain level.
