Hi all,

 

*	The firewall problems with sk.tbm.tudelft.nl and sk-2.tbm.tudelft.nl
are now solved! These hosts are again available from all over the world.
*	The security problem with the Java webstart version of dsol is now
solved. Go to www.simulation.tudelft.nl/dsol/dsol/index.html and follow the

RE: [Dsol-java] Problem in implementing counter

[Peter H.M. J. <p.h...@tb...>]

Hi all, 

 

I looked at the problem and solved it for you. The problem was not in your
code, but in the dsol-full-1.6.2.jar. A fix is as such included in the
dsol-template/lib/dsol-full-1.6.2.jar. 

 

In order for you guys to download this new code, simply update the
dsol-template project and make sure you use this new jar file

 

Peter

Ps I changed your code a bit, update it as well please.

Subject: [Dsol-java] Problem in implementing counter

 

Hi all,

 

Our project's name is BenHenMan Trial 1. We try to make a model of flowing
products or customers through many servers.

We try to use as clear comment as possible so hopefully anyone can
understand the model quickly.

We will like to use counter. The command lines for counter can be seen in
class Model, near the bottom, in statistics part.

The problem is that we do not know if our commands are correct. We think not
because the simulator did not run the model correctly after we added the
lines.

If the lines were deleted, the model could be run just fine.

If any of you has suggestion, it will be very great.

 

Here is the error statement we saw in the dsol logging:

 

21)  10:19:26 PM WARNING: For input string : "0.0"

Re: [Dsol-java] Setting value in an other class

[R.T.H.Chin <r.t...@tb...>]

Hi Joep,

Create a "void addCar()" method to the KmHighWay class. In this method 
add the car to a list of all cars that are in the piece of highway (List 
cars = new ArrayList(); )

Class Model
{
...
void constructModel {
    Car car1 = new Car();
    KmHighWay highway = new KMHighWay();
    highway.addCar(car1);
    ...
    ...
}
}

Does a "model" add a car to a highway, or does the car add itself to a 
highway?
.

Roy

RE: [Dsol-java] Running a DSOL model

[Peter H.M. J. <p.h...@tb...>]

Dear Gerard,

 

The model-class should point to a Java-Style notation of your class. 

 

If you placed the model in the package nl.tudelft.tbm.spm9322.myPackage
package than it should say

 

<model>

 
<model-class>nl.tudelft.tbm.spm9322.myPackage.Model</model-class>

 

Peter

 

If this does not work, please send me the xml file and the jar. Also copy
the log message to the email, I can then see your problem

Hi Peter,

 

Thanks for your answer but unfortunately it doesn't answer my question. I've
seen the xml of the tutorial and what's in it. But I made the tutorial
myself and want to run it with my own files. Where the jar file is on
d:\java\experiment.jar and the Model, Order and Customer class are in the

  <model>

       <model-class>d:/java/Model</model-class>

In the experiment.xml (or whatever you named your model) you should put

Hi,

 

I tried to make dsol tutorial 2.5 myself. I made the Customer class, the
Order class and the Model class. Then I made a jar file of these three java
files. So far no problems encountered. But then I made a xml file and DSOL
kept giving IOexceptions when I tried to open it. When I looked at the log
file DSOL creates I saw (I think) that it is the <model-class> description.
I tried to run it from my own PC the Model.java which I have to open is in
D:\java\Model.java. And the jar file is also in that directory. In
<model-class> I think I have to give the location of Model.java but I fail

[Dsol-java] RE: dsol problem

[Peter H.M. J. <p.h...@tb...>]

Dear Bin,

Some not so smart person in our group has included dsol-turorial.jar in the
class path of the dsol-template and committed these changes to the CVS.
Thanks for noticing! I have replaced the dsol-template on the CVS, so its
clean again.

There are two things you can do:

a) checkout dsol-template again. This will solve the problem
b) If you right mouse click on the project name (dsol-template) -->
properties --> Java build-path --> libraries, you see the class path. Make
sure you remove any reference to dsol-tutorial.jar.

Dear Dirk and others,

I have looked at your code. I think you are on the right track! Keep it
going...

If you update your project from cvs you will see that I made quite some
comments.. All the comments start with TODO Peter. This will help you sort
out what I did (The TODO's give a blue mark in your Java editor).

I would highly encourage others to download the project and to look at the
comments I made ("SPM9322 -port" project on CVS). 

Dirk, mail me what you think and when I can update the new code (there is
still stuff to do for you...)

Subject: [Dsol-java] how to listen to fireEvent?

Dear all,

I've made a "crane" that delivers "containers" every 1..5 timeunits. These
containers should be picked up by several "someVehicles". I would like to
have my crane fire an event, CONTAINER_RELEASED_EVENT. The code for this I
found in the tutorial, section 4.2:

...
public class QuayCrane extends EventProducer {
	public static final EventType CONTAINER_RELEASED_EVENT = new
EventType(
			"CONTAINER_RELEASED_EVENT");
...

private void releaseContainer () {
...
this.fireEvent(CONTAINER_RELEASED_EVENT, this.simulator.getSimulatorTime());
... }
} // end class

My question:

How do I get an instance of my someVehicle to listen to this event? The
events in the tutorial are (so it seems) only used by the Tallies. For this
moment I;m not interested in the prioritization of my someVehicles; I just
want them to respond.

Is this the proper mechanism to create interaction between objects in the
simulation??

Dirk Samson
(PS My very-first-test-project can be found on the CVS Server: "SPM9322 -
port")

RE: [Dsol-java] how to listen to fireEvent?

[Herman v. H. <h_v...@ho...>]

Hi,

I think I can provide you with the answer. the vehicle has to subscribe to 
the event. This is done with the addListener(ListenerInterface listener, 
EvenType event) method which is in the EventProducer class and thuss in your 
crane class. Assuming it is in you r constructor it should look like this:

public class Vehicle implements EventListenerInterface
{
	public Vehicle(Crane crane)
	{
		/** Call super class constructor*/
		super();

		/** Do all other stuff*/

		/** Add our listener*/
		try
		{
			Crane.addListener(this, CONTAINER_RELEASED_EVENT);
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}

	/** Methods*/

}

Hope this helps,

Hi Dirk,

Step 1: make sure youre vehicle implements the EventListenerInterface
Step 2: crane.addListener(someVehicule,CONTAINER_RELEASED_EVENT);
Now your vehicule is subscribed to the CONTAINER_RELEASED_EVENTS. More on
the addListener method is described in
http://www.simulation.tudelft.nl/dsol/event/apidocs/nl/tudelft/simulation/ev
ent/EventProducer.html

Does this solve your question?

Subject: [Dsol-java] how to listen to fireEvent?

Dear all,

I've made a "crane" that delivers "containers" every 1..5 timeunits. These
containers should be picked up by several "someVehicles". I would like to
have my crane fire an event, CONTAINER_RELEASED_EVENT. The code for this I
found in the tutorial, section 4.2:

...
public class QuayCrane extends EventProducer {
	public static final EventType CONTAINER_RELEASED_EVENT = new
EventType(
			"CONTAINER_RELEASED_EVENT");
...

private void releaseContainer () {
...
this.fireEvent(CONTAINER_RELEASED_EVENT, this.simulator.getSimulatorTime());
... }
} // end class

My question:

How do I get an instance of my someVehicle to listen to this event? The
events in the tutorial are (so it seems) only used by the Tallies. For this
moment I;m not interested in the prioritization of my someVehicles; I just
want them to respond.

Is this the proper mechanism to create interaction between objects in the
simulation??

(PS My very-first-test-project can be found on the CVS Server: "SPM9322 -
port")

[Dsol-java] running DSOL

[Peter H.M. J. <p.h...@tb...>]

Hi all,

 

I saw both problems on getting DSOL started. The detailed documentation can
be found at
http://www.simulation.tudelft.nl/dsol/dsol/overview/gettingStarted.html 

 

To simplify the process, here are some tips..

 

*	If you want to play around with the application and have Windows
installed, please download the installer from
http://prdownloads.sourceforge.net/dsol/dsol-gui-1.6.2.exe?download  This
will install a nice start-->programs-->dsol-->dsol application in Windows.
You can now run all the tutorial models (if you are connected to the net)
*	If you want to develop yourself, please check out the dsol-template
project from CVS. This template project contains all the stuff you need. The
one step you have to take is to execute the application.. To do so, expand
the tree of the dsol-full-1.6.2.jar. As you can see, all the classes are
here. Right click on the
nl.tudelft.simulation.dsol.gui.DSOLApplication.class and select run-->Java
Application.

 

If you have any problems,

 

Please mail

 

Peter

 

 

[Dsol-java] Problem starting DSOL

[Harteveld, C <C.H...@ST...>]

Hi everyone,

Eclipse is working fine on my computer, but I do not get DSOL started. Java
is also installed correctly, because after testing the installation
(START-->RUN-->CMD)I receive the message 'java version "1.4.2_04"'. 

First I tried to directly import the jar-files into Eclipse, which of course
did not work out. Then I made use of a Java Build Path (properties project
window) and added the jars of DSOL. This worked fine, except that I cannot
execute anything without the source (Eclipse gives the error 'Source not
found'). 

So I tried to attach files, like the file in the directory j2sdk1.4.2
(src.zip) and others. Unfortunately nothing worked out. 

Does someone knows how to solve this problem? 

Sincerely,

Casper

[Dsol-java] How to get Dsol environment beside using installation files

[Hendy G. <h.g...@st...>]

Dear all,

I hope this is the right forum to ask about Dsol.

I use the spm9322 cvs, but I cannot find a project that uses Dsol so I
can install (automatically I think) Dsol when I use "check out as" on
the project. Maybe I misheard some explanation about the "check out as"
process.

I try to use the link for Dsol too (anonymous cvs), but I don't know
where to put the parameter -d if I add new repository or when I can put
the line cvs -d:pserver: etc.

The last one I have not tried is using the installation file. I think if
I can "check out as" and install the Dsol environment; it will be far
more efficient so I put the last step as "emergency" step.

I thank you for any help you may provide.

Best regards,
Hendy Gunawan

[Dsol-java] Question StockApplication Example

[Fu C. <col...@ho...>]

Hi Peter
I have two questions about StockApplication Example.First, what does 
"interator()" exactly mean? I'm confused about that. In this example, is it 
used to search the list object? The second question is also about that 
"for" loop. why you changed type of "next" to ValueChangListenerInterface 
type. I don't understand this. can you explain it. wait for your 
reply.Thanks. 
for (Iterator i = this.listeners.iterator(); i.hasNext();)
		{
			ValueChangeListenerInterface next = (ValueChangeListenerInterface) 
i.next();

			//Let's inform the guy!
			next.notify(stock);

Kind regards
Colitas

Hi,

1.	In the directory in which you installed j2sdk1.4.2 (Probably =
c:\j2sdk1.4.2 or c:\Program Files\j2sdk1.4.2) there is a file called =
src.zip. Try to attach this file.
2.	This we will discuss next week. If you want to give it a try, visit : =

RE: [Dsol-java] CVS-toegang

[Peter H.M. J. <p.h...@tb...>]

Hi All,

It is the university firewall that is giving these problems. I have sent a
request to DTO and expect an answer any day.

I'll keep all of you informed!

Hello everyone,

last night I tried to use CVS repository at home and encountered the same
problem as Bram. I don't think the firewall at home is responsible for this
problem as I permitted internet access for the application. Maybe the
university firewall is the problem. On sourceforge.net an extra
java-encryption extension is mentionend, but I think this is included in the
latest JRE update,

Michael

Dear Bram,

 

I have tested the repository extensively and could not reproduce your
problem. Could you try to conduct the same action on one of the
computers in the SimLab?  We can than hopefully find out whether your
problem is related to firewall problems on the university network. 

 

Kind regards,

 

Peter

Beste groep,

 

Ik heb een probleem: Als ik een CVS check out wil maken, dan krijg ik de
volgende error terug:

 

Authentication error: com.jcraft.jsch.JSchException: Session.connect:
java.net.ConnectException: Connection timed out: connect  ( ....... OK?)

 

Met de volgende gegevens heb ik geprobeerd toegang te krijgen:

 

Host: sk-2.tbm.tudelft.nl

Repository path: /export/home/spm9322

User: spm9322

Connectiontype: extssh

Use default port.

 

Ziet iemand hier een fout?

Misschien moet ik een poort openzetten voor m'n firewall, maar als dat
zo is, welke dan?

 

Alvast bedankt,

 

Bram Wesselo
