= Printing Out File Contents =
In this example we will study how to read contents of a file from a particular revision of a repository. The 
first steps are just like in the previous example:

{{{#!java
...

public class DisplayFile {

    public static void main( String[] args ) {
        DAVRepositoryFactory.setup( );

        String url = "http://svn.svnkit.com/repos/svnkit/trunk";
        String name = "anonymous";
        String password = "anonymous";
        String filePath = "www/license.html";

        SVNRepository repository = null;
        try {
            repository = SVNRepositoryFactory.create( SVNURL.parseURIEncoded( url ) );
            ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager( name , password );
            repository.setAuthenticationManager( authManager );

            SVNNodeKind nodeKind = repository.checkPath( filePath , -1 );
            
            if ( nodeKind == SVNNodeKind.NONE ) {
                System.err.println( "There is no entry at '" + url + "'." );
                System.exit( 1 );
            } else if ( nodeKind == SVNNodeKind.DIR ) {
                System.err.println( "The entry at '" + url + "' is a directory while a file was expected." );
                System.exit( 1 );
            }

            ...

}}}

Now when we are sure that our url corresponds to a file we read its contents into an {{{OutputStream}}} and 
collect its properties into a {{{Map}}}.

{{{#!java
            ...
            Map fileProperties = new HashMap( );
            ByteArrayOutputStream baos = new ByteArrayOutputStream( );
            repository.getFile( filePath , -1 , fileProperties , baos );
            ...

}}}

Then we find out whether the file is a text or binary file using the MIME type property. If it's a binary we don't 
print its contents. We also print out versioned file properties.

{{{#!java
        ...
        String mimeType = ( String ) fileProperties.get( SVNProperty.MIME_TYPE );
        boolean isTextType = SVNProperty.isTextMimeType( mimeType );

        Iterator iterator = fileProperties.keySet( ).iterator( );
        while ( iterator.hasNext( ) ) {
            String propertyName = ( String ) iterator.next( );
            String propertyValue = ( String ) fileProperties.get( propertyName );
            System.out.println( "File property: " + propertyName + "=" + propertyValue );
        }

        if ( isTextType ) {
            System.out.println( "File contents:" );
            System.out.println( );
            try {
                baos.writeTo( System.out );
            } catch ( IOException ioe ) {
                ioe.printStackTrace( );
            }
        } else {
            System.out.println( "Not a text file." );
        }
        ...

}}}

And finally we run the program and have the following output in our console:

{{{
