Creating related projects in repast with model initialisers

[Dave Murray-Rust-2]

Hi List,

I'm working on a modelling framework based on RepastS, and I'd like to  
create projects which use this, but define their own models. The  
framework specifies a ModelInitializer in scenario.xml, and I would  
like for the related projects to be able to re-use this  
ModelInitialiser, but I cannot get the classpaths set up correctly.

I have added my framework to the standard java classpath, and can  
write code which uses it, and it compiles correctly. However, when the  
model runs, it cannot find the model initialiser.

When editing the Run Configuration:

* leaving the classpath as it is results in not being able to find my  
framework's ModelInitializer[1]
* if I add my framework to the Bootstrap Classpath (as a project),  
then it can't find the Repast ModelInitializer (which mine implements)
[2]
* the same happens if I add it as a project to the User Entries  
section [3]

I tried copying across the model initialiser, but then I also have to  
copy across all the supporting classes etc, and it's going to be a  
maintenance nightmare.

Any thoughts?

Cheers,
dave

1) When setting up the Data Loader, it's only possible to select  
classes in the current project (i've tried adding it explicitly to  
model.score etc). However, if I edit the XML, it works fine with a  
class from a related project. Is this just a limitation of the  
interface?

2) Libraries from related projects do not appear to be on the runtime  
build path, and need to be added manually. Is there something I should  
be doing to make this happen automatically?

Thanks,
dave

Dave,

Simphony uses a lot of dynamic class loading and that can make things  
like this complicated.

  For models, external code that you want to load is specified in the  
score file. The implementation element has an optional "binDir"  
attribute and you should be able to specify your jar in the  
implementation element for the root context. More than one path, jar  
file can be specified in the birDir by separating them with a ",".  
Note that the binDir is relative to the implementation basePath  
attribute. If you can leverage this so that the location of your  
framework is included in the "binDir" then that should work. Note that  
this will change. The current development code uses a different  
simpler and more flexible mechanism and that will become the standard  
ways in the future. Converting from the old to the new should be  
relatively trivial though so I wouldn't let it stop you from exploring  
this solution.

The other alternative is to make your framework a "plugin". All the  
repast code except for the runtime stuff that needs to be on the root  
classpath is loaded as plugins. If you configure your framework as a  
plugin then it should get loaded just as the repast code gets loaded.  
Plugins are defined via a plugin_jpf.xml file that specifies where the  
code for the plugin should be found. If you look through the source  
you'll see lots of examples. The plugin_jpf.xml has essentially two  
sections -- one that specifies what this plugin requires -- for that  
you'd fill in the plugins your framework depends on, and then a  
runtime section that specifies the code that your plugin provides,  
this includes non-repast 3rd party libraries that your code requires.  
See the source for examples. The one in repast.simphony.core is  
probably a good model for you. The last step is to make sure the  
plugin mechanism can find your plugin, the boot.properties file in  
repast.simphony.runtime specifies contains a pluginFolders property  
that specifies where to find plugins.

Dave,

Yes. The interface grabs a data loader relevant classes from the paths  
specified in the model.score. If the classes isn't on any of those  
paths then it won't show up in the interface.

Not sure what you mean here. Do you mean the classpath used when you  
run the model, or the build path used when compiling? If the former,  
you can specific 3rd party libs in the model.score (described in a  
previous message). If the latter, you can use eclipse to specify  
project dependencies when configuring the build path.

[Dave Murray-Rust-2]

Great, thanks for that.

In the end, I got the binDir stuff working. Unfortunately, it's not a  
process that I could ask other people to go through - I'm trying to  
keep the creation of new projects as simple as possible.

Instead, I've refactored my code so it doesn't require any messing  
around with the model initialiser. It's a bit uglier, but much easier  
to set up.

I'll have a look into the plugin mechanism when I have time, though as  
that sounds more like the Right Way to do what I want.

Thanks!
