Okay, that makes sense, although when I want to add a single class to =20=

PEAR in the future, how do I avoid having it go through the whole =20
process again?

I double checked and tthere is no RT directory like you mentioned.  I =20=

am not sure how this affect the overall installation?  Are you saying =20=

that the stubs created in my "classes" directory may not be visible =20
to the bridge software because of its name?

I am currently running this on a dual G4 powerPC and will also be =20
installing this on a dual G5 Xserve server, once I understand how to =20
use the bridge properly.

Hi,

first of all thank you very much for the feedback.

It creates PHP proxies for the classes found in boot
classpath and for the additional libraries specified
on the command line. Depending on how many classes it
has to convert and how fast your machine/VM is, this
may take some time. On my devel. machine the command
completes in less than two seconds. But even 4 minutes
shouldn't be a problem because one usually calls this
command once; during installation.

These are created from the essential .jar files from
the boot classpath. But rt is missing for some reason,
doesn't the apple VM store the runtime into rt.jar?
If not, we have a portability problem -- all other JVM
implementations I've looked at (among them IBM, Sun,
GNU) keep the base classes in rt.jar.

That must be the rt then. This means that we have to
add code which tries to detect the apple VM and rename
the "classes" directory into the standard name "rt".
Do you use a power or intel mac?

Yes, the directory contains java_lang_String.php and
the like.

They're created for convenience.

You should not be printing to System.out, but instead returning a String
[untested]:

	public class HelloWorld {
	       public String sayHello() {
	              return "What up dog!";
	       }
	}

(I guess static methods also work; I can't remember now)

And then use this in PHP [untested, too]:

	// ...
	$x = new java("HelloWorld");
        printf("HelloWorld says '%s'<br/>",
               $x->sayHello());
