Description

Hi all,

I have to configure JNDI by a properties file. For example:

String INITIAL_CONTEXT_FACTORY = "org.apache.qpid.jndi.PropertiesFileInitialContextFactory";

System.setProperty(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);

System.setProperty(Context.PROVIDER_URL, "path/to/file");

Context context = new InitialContext();

Everything works fine until the "Context.PROVIDER_URL" contains a "real" URL instead of a file path. In our example the "Context.PROVIDER_URL" is set by a third party library. But using an URL here causes an FileNotFoundException in [3].

java.io.FileNotFoundException: file:/Users/.../qpid-jndi.conf (No such file or directory)

at java.io.FileInputStream.open(Native Method)

at java.io.FileInputStream.<init>(FileInputStream.java:120)

at java.io.FileInputStream.<init>(FileInputStream.java:79)

Looking at PropertiesFileInitialContextFactory (cf. [2] line 85) it's clear what happens. It tries to open the URL using a FileInputStream. At least on my Mac that doesn't work. My question is whether Qpid should be modified to accept File-URLs since Context.PROVIDER_URL is specified as an URL in [1] and apparently some libraries take it seriously...

Many thanks,

Tobias
