Launch a midlet from another midlet

I need to launch a midlet from another midlet that is running, is it posible and would it be?
regards in advance

[rpalomino],
You are out of luck here. The current CLDC/MIDP specification permits one only MIDlet jar file to be run at a given point in time. You can package as many class files as you wish but only one MIDlet can be launched by the kVM.
If your purpose is to write MIDlet applications that access the same data resource, then instead of launching multiple MIDlets (which is not possible), you can use the RMS data store for persistent information across the different MIDlet class file application.

Hi,
I wants to invoke MIDlet from another MIDlet for the following reason,
I developed a simple chat application. The MIDlets are, Sender & Receier.
Sender home window, will collect sender name,receiver name and number.
Then open another window for Messaging.
On receiver end, after receive the message the user can reply to the message,

Please explain me now, how to call Sender MIDlet from Receiver MIDlet.

Hi,
In order to run midlet from another midlet you may use push registry. Go through the API of that I am not sure but as far as I know push registry is the only solution to that

Invoking a MIDlet from another MIdlet

Hi all,
Consider this scenario,
1. midlet A is running
2. runtime memory of A contains jad and jar files of midlet B in two byte arrays.
(assume some native methods which allows the applications to install, launch and remove midlet and midlet suites by passing the jad and jar files.)
3. midlet A uses launchMIDletsuite method for launching the midlet B by passing the jad and jar files.
4. what will be the state of A after B is launched. (running?, waiting?, destroyed?)5. Whether B is a subset of A. ie. Will A gets control back after B is destroyed.
6. if not, is there any way to get the control back to A?
Thanks in Advance

I can't see any needs of seperate MIDlets here.
You can use Canvases and Forms.
Your app could start with a authentication Form. If the user is invalid, show hime the registration form.

Call Midlet from another Mitlet suite

I know that this topic has been discussed previously, but all threads I have seen are just discussing to call a Midlet in the same Midlet suit. My question is:
Can I find out what Midlets are installed and can I call a Midlet in another Midlet suite using MIDP 2.0? And if possible, how can I do this?
Thanks in advance.

Explain in more detail, please. When I cause from one MIDlet another MIDlet I receive:

Problem with calling a midlet within another midlet

hello friends,
can a create an instance of a midlet within another midlet.i tried to call , but i have got a Security exception. plz comment on this ..
regards..

"For security reasons, it is assumed that MIDlets within a MIDletSuite are packaged
together for a reason and should be able to interoperate. What's implied here is that the
MIDlets share a name space; in other words, each MIDlet in the MidletSuite can "see" one
another. Because they can see one another, they can launch one another (Class.forName
metaphor).
In contrast, one MIDletSuite cannot launch another MIDletSuite. That's because they do not
share name spaces. Since the CLDC+MIDP does not have a security manager (too big and
complex for small devices), the MIDP expert group felt it more prudent to limit the interaction
of downloaded applications to those that are packaged together by the provider."extract from Sun

How to embed and launch ipa file from another ipa package created using Air for iOS

Hi Guys,
Anybody out there knowing how to embed and launch ipa file from another ipa package created using Air for iOS ?
I am having 1 ipa file created using Xcode, Now i need to include that file in my ipa Package which is created using Flash CS 5.5 and Air for iOS. Also i need to know how to open my 1st ipa file from AS3 ?

Launching a MIDlet from another

Hi All!
I need to create a menu.When one selects a particular option they should be redirected to another midlet .Need basics of creating forms .
Desperately need for a project whose deadline is on our head .
How do i go abt this ?
Thanks .

jhd
i, this is not big problem and u can meet ur deadline easily if i m not late to answer u.
if u want to create a main menu when u are launching and first screan appear with your midlet name then there is way to create different Midlet
and then if u are using wireless toolkit you have to goto
Settings>Midlet where u find options for that and u can set ur midlet classpath there.
you can see the game demo given in wtk23's apps folder.
and if u are suppose to wanting that ur application start with main menu and after selecting one u r agin going to nested menu and from there u want to call other midlet then u can use this code
class midlet1 extends Midlet
which u want to call from
class midlet2 extends Midlet
//here u have to destroy midlet2
//create object of midlet1
midlet1 m = midlet1();
this will simplycall to midlet1 and new object were created for that
with new display........
but for standard coding u have to use any displayable item(Form,List..)
and when u are selecting menu u just setCurrent display to this new displayble item and will work fine.

MIDlets to another one in same application.
I am devloping a application in which I am using more than two MIDlet and I
want to transfer Parameter from one MIDlet to another one.
I just explain what I have done....
I made a MIDlet "A" and "B" in the same project using NetBeans IDE.
In MIDlet "A" I create the Object of MIDlet "B" so that the constructor of
MIDlet "B" is called and parameter can be transferred.
But when I run the program it shows me two MIDlet on the screen, that I

If you create two MIDlet in a midlet suite, it will display as you mentioned means you can't change the display style.

How can i open a midlet in another midlet-suit?

My question is : i want to creat a midlet A. In this midlet ,i can download another midlet B and install it. The new downloaded midlet B ican be presented in a part of midlet A. In midlet A, i can open midlet B,even control it.
Is my idea impossible? or not?
i have read something about this topic,the answer is impossible. Because the CLDC is not support this method. But i am not sure it.If u know something about these ,please give me a answer!thank u!

It is possible if both your MIDlets are in the same MIDletSuite - see http://forum.java.sun.com/thread.jspa?forumID=76&threadID=290808. If it's 2 MIDletSuites, then it's impossible.

Launching a JFrame from another JFrame

Hi,
I have a JFrame containing a menu(buttons). When I click on a button, I want that it launches another JFrame.
I tried making use of the code
Process p = Runtime.getRuntime().exec("java CreateStudentRecord");
where CreateStudentRecord is the JFrame I want to launch. however this did not work.
Can anyone help me find out how I can launch another JFrame when I click on a button within another JFrame.
Thanks,
Rahul.

How about just using the following:
private CreateStudentRecord csr;
JButton b1 = new JButton("New Student Record");
b1.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e){
csr = new CreateStudentRecord().show();
