             Summary: PropertiesFileInitialContextFactory cannot open file URL
                 Key: QPID-3971
                 URL: https://issues.apache.org/jira/browse/QPID-3971
             Project: Qpid
          Issue Type: Bug
          Components: Java Client
    Affects Versions: 0.14
         Environment: MAC OS 10.7, java version "1.6.0_31"
            Reporter: Tobias Unger


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 [2] 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
