[jcifs] java.net.MalformedURLException further analysis

[andrea.lanza at frameweb.it]

I tried to follow the idea proposed by Eric, and I put part of that code at
the real beginning of my class, in order to see what happend.

My final idea is that Tomcat could be innocent, and I am doing something
wrong.

Here is the code I added

    try {
// added by Andrea for testing purpose, 11/12/2002
String ver = System.getProperty( "java.version" );
if( ver.startsWith( "1.1." ) || ver.startsWith( "1.2." )) {
   System.out.println( "jcifs-0.7.0b4+ requires Java 1.3 or above. You are
running " + ver );
} else {
   System.out.println( " JAVA Version is OK. You are running " + ver );
}
String pkgs = System.getProperty( "java.protocol.handler.pkgs" );
if( pkgs == null ) {
   System.out.println("pkgs==null");
   pkgs = "jcifs";
} else {
   System.out.println("pkgs NOT null: actual value:" + pkgs);
}
try {
   System.setProperty( "java.protocol.handler.pkgs", pkgs );
} catch (SecurityException ex) {
        System.out.println("SecurityException "+ ex.toString());
 }

// now I test if System.setProperty worked out
pkgs = System.getProperty( "java.protocol.handler.pkgs" );
if( pkgs == null ) {
   System.out.println("2nd time: pkgs IS STILL null,setProperty did not
work");
} else {
   System.out.println("2nd time: pkgs NOT null: actual value:" + pkgs);
}


FileInputStream localin=null;
try {
   String filename = System.getProperty( "jcifs.properties" );
   if( filename != null && filename.length() > 1 ) {
         System.out.println("filename value is: "+filename );
         localin = new FileInputStream( filename );
         jcifs.util.Config.load( localin );
   } else {
        System.out.println("filename value is null or 0 legth ");
   }
} catch( IOException ioe ) {
      System.out.println("IOException: "+ioe.toString());
}
Class.forName( "jcifs.Config" );
System.out.println("Class forname was successful, no exceptions ");
sourceFile = new SmbFile("smb://");
System.out.println("new SMBFile was successful, no exceptions");
// END OF added by Andrea for testing purpose, 11/12/2002
......
then there is the catch and so on.......


When I get the usual error  ( java.net.MalformedURLException: unknown
protocol: smb ) I can read in the standard out file
(Sorry, I am used to use standard output, non standard error....it's a mine
bug!)

stdout file:

Bootstrap: Create Catalina server
Bootstrap: Starting service
Starting service Tomcat-Standalone
Apache Tomcat/4.1.12
Bootstrap: Service started
 JAVA Version is OK. You are running 1.4.1_01
pkgs==null
2nd time: pkgs NOT null: actual value:jcifs
filename value is null or 0 legth
Class forname was successful, no exceptions
Error in SmbPrx.execute() : java.net.MalformedURLException: unknown
protocol: smb


So what can we see ? that System.getProperty worked and System.setProperty
too......
In addition to the entry in stdout (Error in SmbPrx.execute()......), in
standard error I print the StackTrace

the line 355 in SmbFile.java appears to be :
354 │    public SmbFile( String url ) throws MalformedURLException {
355 │        this( new URL( url ));
356 │    }

So again the question is: How can I be sure to use the correct java.net.URL
?
Following the source of java.net.URL (java 2) the lines 425 and  476 are
constructors "redirected" to the "standard 3-argument" constructor for URL

    public URL(URL context, String spec, URLStreamHandler handler)   throws
MalformedURLException


line  586 is part of this last constructor method
line  586 and neighboroud:

582 │          // Get the protocol handler if not specified or the protocol
583 │        // of the context could not be used
584 │        if (handler == null &&
585 │             (handler = getURLStreamHandler(protocol)) == null) {
586 │             throw new MalformedURLException("unknown protocol: "
+protocol);
587 │         }


So , conforted by the line numbers (better than nothing ! )  I believe to
have the right  java.net.URL version
I think that  the getURLStreamHandler(protocol) returns null.

But here I stop, becouse everything seems to be OK to me (java version
right, java.net.URL correct, jcifs in classpath and reachable,
getSystemproperty and setSystemProperty working...)

Next step, I will try to start tomcat adding the
-Djava.protocol.handler.pkgs=jcifs if I will discover where to add that
argument
