[Php-java-bridge-users] Installation of PEAR classes for java classes help needed!

[<php...@li...>]

Hi all,

First off, my knowledge of Java is very limited (thus the need for  
the PHP/Java bridge).

I have compiled and successfully installed the bridge for PHP 5.1.6  
for Mac OS X and wanted to install the PEAR class that represents a  
sample java class I have called HelloData (which simply prints "Hello  
the date is: mm/dd/yyyy").  I used the following command as per the  
instructions:

[PROMPT] sudo java -jar /usr/local/php5/lib/php/extensions/no-debug- 
non-zts-20050922/JavaBridge.jar --convert /usr/local/php5/lib/php  
HelloDate.jar

This ran for about 4 minutes before completing.  I was astonished  
that it would take so long.  After it completed I looked in the PEAR  
directory (/urs/local/php5/lib/php) and found several new directories:

drwxr-xr-x      5 root  wheel     170 Sep 10 14:19 HelloDate
drwxr-xr-x    416 root  wheel   14144 Sep 10 14:19 charsets
drwxr-xr-x   9200 root  wheel  312800 Sep 10 14:19 classes
drwxr-xr-x     46 root  wheel    1564 Sep 10 14:19 jce
drwxr-xr-x     82 root  wheel    2788 Sep 10 14:19 jsse
drwxr-xr-x    119 root  wheel    4046 Sep 10 14:19 laf
drwxr-xr-x    106 root  wheel    3604 Sep 10 14:19 ui

The first extra item makes sense, since it is the Java class I asked  
to be created in that command.  But the rest are a mystery to me  
(isse?  laf?  ui?).  And the "classes" directory is HUGE.  It looks  
like it has thousands of items (are these classes too)?

My questions are:
1) What are all those other directories for when I only asked for my  
sample class to be made into a PEAR class?

Thanks for the assistance.

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.

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,

you could set the bootPath to an empty string in line
103, see
http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/bridge/Snarf.java?view=annotate&sortby=date

In the future we should avoid creating stubs if the
files already exist.

> you mentioned.

Thanks. I think the easiest way to fix this is to
check if the created directory contains
java_lang_System.php. If it does and the dir doesn't
have the name "rt", rename it. I have created a ticket
for this bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=1557227&group_id=117793&atid=679233

> am not sure how this affect the overall

The Lucene search and Itext PDF examples use something
like:

require_once("rt/java_lang_System.php");
require_once("rt/java_awt_Color.php");

When rt doesn't exist, those examples will not work.

> to the bridge software because of its name?

The require_once() in the above examples will fail.

I thought so. There's a chance that the intel macs are
more compatible with the Sun VM.

The file "java_lang_System.php" does indeed exist in my "classes"  
directory.  So it looks like it is just a naming issue (at least with  
Power PC machines).  I will have an Intel Mac laptop at the end of  
the month so can test the same install there to see if there is a  
difference.

Okay, so it is just an issue with where you do an include.  I was  
concerned that the bridge software itself would look for the "rt"  
directory and run into problems if it could not find it.
