Re: [JBoss-user] Setting & Accessing Resource Files in JBoss
Oh i get it, the servlet can call the session bean
to get the value from the resource.
Thanks, Ivan

Ivan,I have tried to do that, but since i don't know
how to get to the EAR's classloader, i didn't succeed with loading the
resource from the EAR. I finally decided toload it exlusively from the
bean and provide a method like loadResource() and storeResource(...) in
that bean, so that i can have access to the same resources from wherever i
want.Hope that helps ...CheersLorenzoIvan

Hi Ivan,A resource can be anything from a config
file to a class. You can access a property file as well as a resource.
Resources don't have a specificstructure.

Hi Burkard,As far as i know you should not
access files directly through file IO operations, or make assumptions
on an existing filesystemat all in EJB's. The "/" in a
resource name is relatively seen, the package root from the class that
calls the getClass().getResourceAsStream() method. This way you
canpackage resources with the jar and don't have to create and
manage external directorier (on different operating systems). The "/"
used in resources works for all operating systems.

Thaks a lot to all of you for your help! I finally made it! I was just missing the initial '/' in the path for the resource file in the deployment descriptor... after correcting that detail everythin worked perfectly. Just for the record, if anybody can use the strategy I used on this: I needed to access not to a single one resource file from a bean, but to several! So I defined the resource for this Stateless Session bean like a Properties file. Each element of the list in there is a pair of the form ([RESOURCE-NAME]=[PATH]) so now I can load every single file from that list accessing first to the .properties file, get the path I need at one moment, and load it. That way I don´t need to define every single file as an !! Thanks again! Bye! Jorge Suarez Commexnet Co.

Re: [JBoss-user] Setting & Accessing Resource Files in JBoss
Hi Jorge,
Your class is probably not finding the resource. The directory "/config"
has also to exist in the jar.
It really depends from which class you call the getClass().getResourceAsStream()
method.
The classloader tries to load relative or absolute (depending if you add
a "/" or not in front of the resource path) from the package location of
the class that calls
the getClass().getResourceAsStream() method. For example : if you make the
getClass().getResourceAsStream() call from your EJB class, then the classloader
tries to
load the resource from the jar that contains the beans.
If you call the getClass().getResourceAsStream() within a servlet/servlet,
you have to deploy the resource within the Web Archiv.
In my case for example i have following deployment structure:
application.ear
--META-INF
--application.xml
--application.jar <-- This is the jar that contains the ejb-classes
--META-INF
--ejb-jar.xml
--jboss.xml
--config <-- This is the directory that contains the resource
- config.xml <-- this is the resource itself
--com
-- The rest of my ejb-classes
--application.war
In my stateless session bean i do following:
private String getConfigurationFilename() throws NamingException{
String theSearchConfigurationFilename;
InitialContext theInitialContext = new InitialContext();
theSearchConfigurationFilename = (String)theInitialContext.lookup("java:comp/env/ConfigFile");
return theSearchConfigurationFilename;
}
private void configure() throws ConfigurationException, RemoteException{
try{
myConfigurationResourceName = getConfigurationFilename();
log("configure() : trying to load configuration from " + getClass().getResource(myConfigurationResourceName).getFile());
java.io.InputStream aConfigStream = getClass().getResourceAsStream(myConfigurationResourceName);
.
.
}catch(Exception anException){
throw new EJBException(anException);
}
}
I hope, that this helps you solving the problem
Cheers

Re: Re: [JBoss-user] Setting & Accessing Resource Files in JBoss
Hi,
just guessing but wouln't you lookup the file from the root-dir if you use
/config/ConfigFile.xml??? you are getting the string correctly, right?
so the two alternatives would be using something like config/ConfigFile.xml,
but I think that will be JBOSS_HOME/bin/config/ConfigFile.xml of suit your
/config to match someplace in your file structure, i.e.
../conf/tomcat/ConfigFile.xml.

Re: Re: [JBoss-user] Setting & Accessing Resource Files in JBoss
Wow, Thanks a lot Lorenzo... Now I have better hopes!
I still have some Issues with this:
I made it to code and deploy a Session bean that access to a resource file from the
source code you send me. I got the correct name and location of the file with
theResourceName = (String)theInitialContext.lookup("java:comp/env/" +
anEvironmentName);
here I can see the exact valu I gave in the deployment descriptor
(/config/ConfigFile.xml), I also deployed the file
same name and in the same directory in the .jar file.
But with
java.io.InputStream theInputStream = getClass().getResourceAsStream(theResourceName);
I allways get null!! :( (of course I can´t read the Stream afterwards, then I get the
NullPointerException)
I´ve been working around with this, but nothing helped. Do you guys have any clue?

Re: [JBoss-user] Setting & Accessing Resource Files in JBoss
Hi,
You can do something like this:
First create an environment entry in your ejb-jar.xml file like:
ConfigFile
java.lang.String
/config/ConfigFile.xml
private String getResourceNameFromEnvironment(String anEnvResourceName) throws
NamingException{
String theResourceName;
InitialContext theInitialContext = new InitialContext();
theResourceName = (String)theInitialContext.lookup("java:comp/env/" +
anEvironmentName);
return theResourceName;
}
private void loadResource(String aEnvResourceName){
String theResourceName = getResourceNameFromEnvironment(aEnvResourceName);
java.io.InputStream theInputStream =
getClass().getResourceAsStream(theResourceName);
}
Cheers
