How to read *.properties files?

[nlmarco]

Hello *,

maybe I'm wrong, but I've read some time ago, that you should not use java.io.* within EJBs. Thus, how can I read a configuration from a *.properties file?

Is the following way really forbidden (even though it works)?

public void ejbCreate() throws CreateException
{
try {
Properties props = new Properties();
props.load(MyBean.class.getResourceAsStream("MyBean.properties"));
// ...
}

Thanks a lot in advance for your help!

Best regards, Marco.

Using java.io is forbidden because a filesystem is not considered a safe medium to use. You should use a database instead, for example.
You could create a property table, with a PropertyEJB CMP bean, in which you will store your properties.

Of course, you can still use java.io in a WAR (it is not forbidden in a WAR). That's what Struts do with its configuration file.

...alternatively read in the properties to a singleton or some other application config object if Entity Beans are a non-starter (or you have no DB)

Hello!

Thanks a lot for your replies! I'm using environment variables in my deployment descriptor, now. They have the disadvantage, that I cannot change them runtime within an EJB, but I think that I can live with that.

But what is a "singleton" or "some other application config object"? Could you render that more precisely, please?

Thanks a lot!

Best regards, Marco :-)
