reading a file in web root in a Tapestry fashion
Hello,
Sure it is a beginner question, but I'm a beginner :o)
I would like to read a file which is located in the web root folder, and
put it in a String.
I had a look around the Internet and found some tricks :
A la "Servlet" :
ServletContext theApplicationsServletContext = (ServletContext)
this.getExternalContext().getContext();
String realPath =
theApplicationsServletContext.getRealPath("/resources/images");
File file = new File(realPath + File.separatorChar + justFileName);
A la "Rife" :
import com.uwyn.rife.tools.FileUtils;
URL resource =
getClass().getClassLoader().getResource("model/WordList.txt");
final String wordlist = FileUtils.readString(resource);
Please could you tell me what are methods and usages with Tapestry ?
Thanks
cyrille

Re: reading a file in web root in a Tapestry fashion
Posted by Cyrille37 <cy...@gmail.com>.
More generally, I would like to know how to access Application
environment for a service class.
So, Is there somewhere in Tapestry a Static method that could return
some global Application information ?
For example, from a Service (Business) Class I would like to:
- get the Application Web Root to read a file
- get a key from a property file which stand in WEB-INF/
Any idea ?
Thanks

Yes, that's it. Thanks Len.
And Please, how to without annotation ?
I'm looking in Tapestry Javadoc for some static method and I could not
find one.

This only works from inside a Tapestry page because this is linked to
the servlet context which knows about the real path. To a standard class
you need to pass the information somehow.
Without injection it can be:
getPage().getRequestCycle().getRequestContext().getServlet().getServletContext().getRealPath(fileName);

I could not use an abstract class. How will I instantiate it ?
I would not like to instantiate it with an IoC but like a normal Java
Object.

for example, you can not expect hivemind to inject IEngineService
automatically since there are many services implementing this interface
(PageService, ExternalService, DirectService and so on)
Otherwise it works fine.

Hi,
the rules are quite simple, there have to be only one service of the type ... otherwise you have to specify what service
do you want to ...

I do not really understand.
Do you mean Hivemind will do that automatically ?
What are rules ?
Do you know the documentation about that ?

yes, thats it - BTW, you don't need an explicit set-service.
just exposte a setter in your implementation class, and hivemind will
autowire it:
public void setServletContext( ServletContext ctx) {...}

Re: reading a file in web root in a Tapestry fashion

I've resolved the case with Hivemind.
I pass to the ObjectFactory the ServletContext to get a root path and
the relative filename.
<service-point id="hangmanFactoryService"
interface="games.hangman.service.HangmanFactory">
<invoke-factory>
<construct class="games.hangman.service.HangmanFactory">
<set-service property="servletContext"
service-id="tapestry.globals.ServletContext"/>
<set property="wordsListFilename" value="WordsList.txt"/>
</construct>
</invoke-factory>
</service-point>
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="hangmanStateObject" scope="session" >
<!-- <create-instance class="games.hangman.service.Hangman"
/> -->
<invoke-factory object="service:hangmanFactoryService" />
</state-object>
</contribution>
I would have liked only the Hivemind's contribution entry, but to pass
parameters to the instance I've understood that we have to use a
Factory. So two Hivemind's entries.
Perhaps it could be lighter with the Hivemind's "Lightweight Instance
Initialization"
http://hivemind.apache.org/instance-initialization.html
But I do not understand how it works ...
I would have liked something simple as:
<bean id="hangman" scope="session"
class="games.hangman.service.Hangman" >
<property name="servletContext"
ref="tapestry.globals.ServletContext" />
<property name="wordsListFilename" value="WordsList.txt" />
</bean>

On which class do you need to access the resource?
Cheers,
