You know, "agletsd -port 9000"? If one is listening, could it be that you have a firewall that prevents the origin aglet server from connecting to port 9000? Are you able to connect with telnet to that port? You should try that, just to see if the connection succeeds. Let us know if you have fixed the problem in the mean time and how, it might need to go into the documentation.

I haven't heard reports of Aglets running on Java Platform, Micro Edition. For that matter, I haven't heard reports of Aglets running on non-Sun Java environments, either. Can anyone update us on Aglets with JavaME and Aglets with non-Sun Java?

Hi!
I have had the same problem. It seems there is a bug in the standard
security policy file or it is not working with a standard windows system
anymore...
If you just remove all the text in the file and write:
// Do what you will
grant {
permission java.security.AllPermission;
};
There should not be a problem. Be aware that this is not safe !!!
But you can start from there and see if it works. I

I hope I have understood your problem correctly.
The graphical way would be from Tahiti's menu to go to Options -> Security
Preference. In the resulting dialog, type file:/C:/XXX/XXX/ with forward
slashes, as it is a URL. Then click the "Add" button under "Code Base".
Select the freshly added URL and then from the right side add permissions.
First you select a permission type from the drop down list at the top, then
you edit the parameters of the permission in the fields at the bottom, then
you click on the "Add" button from the right half of the dialog to add the
permission to the list. You will see the freshly added permission in the list
under the "Add" button.
I find the interface not too friendly towards beginners. It assumes you
already know how Java's policy system works and what parameters to use in
order to instruct the Permission classes to enforce the behaviour you want.
There are few clues in the interface about what the Aglets specific
permissions mean and I found little documentation about it.
Another way to go about it is to edit the policy file by hand. It is located
at ${user.home}/.aglets/security/aglets.policy . The Aglets policy system
exists since Aglets was compatible with JDK 1.1.3, so it did not use the
Java2 policy system, but imitated it. For this reason the Aglets policy
system is not a pure Java2 policy system and you may find small discrepancies
between the Java documentation and the way Aglets policies work. However, you
can mostly use Java documentation and test your application whenever you
apply it to Aglets. The syntax of Java policy files is documented at
http://java.sun.com/j2se/1.5.0/docs/guide/security/PolicyFiles.html . You can
try older versions of that document, which are closer to Aglets. You can also
use the sample Aglets policy file that you can find at
${user.home}/.aglets/security/sample.policy .
Find out what the Java-specific permissions mean at:
http://java.sun.com/j2se/1.5.0/docs/guide/security/permissions.html
For the Aglets-specific policy objects, since the source code is available you
can find out from it what parameters they use and what they do. They are
classes whose names usually end in Permission or Protection. Good luck with
this!
Sun's 'policytool' tool has a GUI that may help you generate policy files,
although Aglets policy syntax is slightly older than that of the newest Sun
JDKs.
Hope this helps,
Thomas.

Hello at all,
I'm new with java and aglets, and i hope that you can help me.
I must to do a project using aglet and other file ".class" in a
particular directory (c:\XXX\XXX).
Now the project run only if I don't use the "Security Preference" of Tahiti.
I read that i must to modify the security pilicy, but i'm not successful.
Now my question is the follow:
If i want to modified the Security Preference of tahiti to include the
use of file ".class" in the directory c:\XXX\XXX what i do?
thanks in advance

Dear Khaled, Yes it is possible, but not directly using the IP address, but the ATP address (Aglets Transfer Protocol). I suggest you to run Tahiti and explore it the most as you can.

Hi every body, I want to develop an example of migration of agents between two computers eg. The Agent A moves from the computer 1 (IP address xxxxxxxxx) to another computer (IP address yyyyyyyyy). Is it possible to do this with the actual version of Aglets? Thanks for your answers.

Dear Abdul-Gabbar, On Thursday 09 March 2006 14:07, Abdul-Gabbar T. Al-Tamimi wrote: > If I need an aglet to travel through a network with its signature. > Firstly, it is included in a jar file, then the jar file will be > signed. How to create and dispatch this aglet included in a jar > file ??? I assume you use Tahiti as interface of the aglets server. Most of the job of creating and dispatching an aglet stored in a JAR is identical to working with one of the example aglets. The difference is that you need to provide in the 'Create Aglet' dialog the path to the JAR file in the 'Source URL' field, like this: file:///home/user/myAglet/signedAglet.jar I don't know exactly how the path would look like for Windows. Maybe if you put the JAR in the 'public/' directory of aglets you can write the Source URL in a different way, too. If you use restricted aglet permissions, you need to adapt the codeBase given in the policy file to the URL given in the 'Source URL'. When the aglet is dispatched, I think the whole JAR is sent to the destination, but I am not sure. Verifying the signature at the destination may not be straightforward. There was a related question a while ago about accessing an aglet's bytecode at the receiver. I don't remember he question getting an answers explaining how it can be done. There were only a few suggestions, that with the current server code the aglet will not be able to verify its own integrity, so the server will need to be changed. If you want to retrieve the thread, surf to the aglets page in the sourceforge site, go to the mail section, from there to the archive of the aglet-users mailing list and there search for 'aglet bytecode' requiring all words of the query. > Does there any other way to associate a signature with the aglet > during its roaming ? I can think of two ways: - compute the signature offline, save it in a file, let the aglet read its own signature from the file, then send it roaming - write a launcher aglet that calculates the signature of the worker aglet, then creates the worker aglet with the create(...) method of AgletContext and provides an object containing the signature as the 'init' parameter There are lots of details to get right, good luck! Since part of your question is about using the aglets server, I have copied in the aglets-users mailing list, too. It would be nice for you to provide a "Subject" for your messages towards the list, to make it easier to find back your question and its answers in the future. The words "aglet bytecode" I gave you above for finding the thread are taken from the Subject of those messages. :) Hope this helps, Thomas. -- [Random fortune cookie]: Oh my god, dude! |

Hi All, If I need an aglet to travel through a network with its signature. Firstly, it is included in a jar file, then the jar file will be signed. How to create and dispatch this aglet included in a jar file ??? Does there any other way to associate a signature with the aglet during its roaming ? I urgently need to solve this problem. Help me please. Thank you very much A.Tarish |

I recommend you to read the User's Manual for first details (available for example in section Files on the Aglets Sourceforge page), then checkout a copy of the source tree with anonymous CVS and start tinkering with the server code. If you only want to write aglets for this platform, then I suggest you to register to the aglets-users mailing list (this one is for developing the server), read the User's Manual, then continue by taking a look at the example aglets that you can find in the aglets-2.0.2-src.jar file in directory src/examples/. The JAR is really just a file archive, extract them with 'jar x aglets-2.0.2-src.jar'.

Hello All ,
I want to do have the following done . But looks like i messed up some where.
When ever i start the Thahiti server ,i want some aglets(ex : task.ManagerAgent ) automatically be loaded on to the Thahiti server and be running till Thahithi is closed.
For this I looked into the Aglets UserManual ( section 5.2 Configuration Files , configuration of "aglets.props" file ) and on page 66, third configuration from top ,following it was mentioned as follows
------------------------------------------------------------------------------------------------------------
# (optional) Comma(,) separated list of URLs(or class names) of aglets
# which should be created just after the server starts.
#aglets.startup=
# examples.hello.HelloAglet,\
# atp://yourhost:434/examples.hello.HelloAglet
------------------------------------------------------------------------------------------------------------
But when itried this it was not working for me for some reason.
In my system when i installed aglets2.0.2 "aglets.props" file was created at C:\java\aglets\cnf ( where my AgletsHome is :C:\java\aglets) .
I changed the above entry as follows ,since i wanted the "task..ManagerAgent" agent
to be started immediatley after the Thahithi started.
------------------------------------------------------------------------------------------------------------
# (optional) Comma(,) separated list of URLs(or class names) of aglets
# which should be created just after the server starts.
aglets.startup=task.ManagerAgent
# examples.hello.HelloAglet,\
# atp://yourhost:434/examples.hello.HelloAglet
------------------------------------------------------------------------------------------------------------
I used the following URL entry also
------------------------------------------------------------------------------------------------------------
# (optional) Comma(,) separated list of URLs(or class names) of aglets
# which should be created just after the server starts.
aglets.startup=atp://191.192.3.152:434/task.ManagerAgent
# examples.hello.HelloAglet,\
# atp://yourhost:434/examples.hello.HelloAglet
------------------------------------------------------------------------------------------------------------
Does the "aglets.props" file that i am changing is the correct file or is there any other place i need to do these modifications to get the desired functionality ?
Please advice me and help me .
Thanks
Phani.

Hi Luca, I am just browsing through the "aglets-developer (read-only)" posts and replies on source forge.net. I find one of your reply (solution) post to Mr.PhaniIndhra's request , interesting and looks like it is related to my work. For your easiness i attached the post following to this mail. I have a question on your solution to Mr.PhaniIndhra. In your solution you asked to "exploit an agent (called MangerAgent) as interface to the running tasks, thus incoming agents asks for running tasks to it and and communicate to it when tasks are finished." But how can the in coming agent send a message to the ManagerAgent..? Incoming agent does not know the proxy on which the Manager is running so it can not send the message to the Manager agent. How can we solve this ..? Do you have a mechanism that will tell all the incoming agents about the proxy that the ManagerAgent is running. Appreciate your help on this.

Hello Luca and All ,
I am able to send a message from the CreatorAgent to
the SlaveAgent ( created by the creator Agent in the
same context )in the same host . But I am not able to
send a message back to the CreatorAgent from the Slave
Agent. How can i achieve this .Please let me know.
First i tried getting the proxy it is from the
SlaveAgent using ..
AgletProxy localProxy =
this.getAgletContext().getAgletProxy(getAgletID());
and used ..
localProxy.sendMessage(new Message("HELLORECEIVED"));
to send message to teh creator. But the message is
sent to the Slave Agent itself.
Then i tried passing the CreatorAgent proxy to the
SlaveAgent and used that in sending the message back.
Still i did not receive the message in the
CreatorAgent side.
I am attaching the simple files i used for complete
local messaging. PLease lte me know i f ia m doing
some thing wrong.
And if you have any other suggestions or any other
mechanism that will achieve this functionality of
complete messaging please let me know.
Attached are source code files (LMCreatorAgent.java &
LMSlaveAgent.java ) i used .
Appreciate your help on this .
Thanks
Anil

Hi Luca and ALL ,
The reason why messaging was not working was , i had
a typo which cannot be easily find in the
handleMessage() function . I wrote the name of the
function wrongly as "handleMessgae()" .Thats why
messaging was not working.
Now local messaging and remote messaging is working.
But i have a new problem with remote messaging.
When i send a message from a CreatorAgent to the
SlaveAgent ( which was created in the CreatorAgent
context and dispached to another host) , SlaveAgent
is able to receive the message. But how can i send
a reply message from the SlaveAgent to the parent now
..?
I guess the sendReply() function does not work for
this type of reply messages.
So I tried passing the "parentproxy" as follows while
SlaveAgent being created.
AgletProxy parentProxy =
this.getAgletContext().getAgletProxy(getAgletID());
AgletProxy localProxy = context.createAglet(null,
"fluca.SlaveAgent", parentProxy);
On the SlaveAgent side tw o function s "oncreation()"
and "handleMessgae()"
are coded as follows, to send a reply message to the
CreatorAgent.But it is not working.
public boolean handleMessage(Message msg)
{
if( msg.sameKind("HELLO"))
{
try
{
//Send message to parent
parentProxy.sendMessage(new
Message("RECEIVED"));
System.out.println(" Sent Hello
received Message to Parent. i.e to RMCreatorAgent
");
}catch(Exception e)
{
System.out.println(" RECEIVED reply
Message is not sent .Exception is :"+e);
e.printStackTrace();
}
}
return true;
}
public void onCreation(Object init) {
addMobilityListener(this);
System.out.println(" Called oncreation().");
parentProxy = (AgletProxy)init;
System.out.println(" parentProxy is
:"+parentProxy);
}
On the CreatorAgent side i added the following
handleMessage(Message msg) function to receive the
messages sent fro mSlave Agent.
public boolean handleMessage(Message msg)
{
System.out.println(" Just entered in the
handleMessgae () of CreatorAgent .");
if( msg.sameKind("RECEIVED"))
{
System.out.println("I am CreatorAgent.Reply
Message received from SlaveAgent is :.");
System.out.println(""+msg);
}
return true;
}
Please let me know how to send a reply message from
SlaveAgent to the Creator Agent so that the
communication is complete.
