PHP5 is quite OK.
Works perfect this way, Thx!

OK, here you go, since the log-file is 70k I just put it online [1]
instead of posting it to the list.
What I am doing is only proof-of-concept for an exam, no
production-code. performancewise(and stability) I should probably rather
do a lot of the stuff in a native java-library instead. It involves
heavy usage of CORBA, so that might be causing the problem?
Although, it pretty much looks like it was really possible to use a java
CORBA-library within PHP.

hopefully it is of some help...

$Array = new java_class("java.lang.reflect.Array");
for($i=0; $i<$Array->getLength($nameValues); $i++)
echo $nameValues[i] . "\n";
should work if you have PHP5 (please see
tests.php5/arrayInterface.php). In PHP4 the bridge uses the same method
as the ext/java: it copies all elements from the java array into a PHP
hashtable $nameValues. I don't know at the moment how it is possible to
ask a PHP hash table for its length.
> It seems not possible to access the java.length property '$nameValues->length'
The bridge accesses java via reflection. For some reasons Sun decided
to wrap arrays differently (via a separate java.lang.reflect.Array
interface).
> 'foreach ($nameValues as $value) { echo "soemthing" }' work.
This should work in both PHP4 and PHP5, please see
tests.php5/iteratorInterface.php. The example uses a Map, but
getPhpMap() works for Arrays, Maps and Collections.
Can you please set the log level to debug and send the result? I am
looking for the output of: logDebug("returning map for "+
value.getClass());
> Do I need to modify the native Java-Class so it provides another

Not necessary. I think that for some reason the value is neither an
Array, nor a Map or Collection. We'll see.

Hi,
for a few days I have been testing the php-java-bridge and I must admit
it seems pretty mature and useful. :->
One slight problem remains though. I do need to call a java-method which
will return a (dynamic sized)Java-Array of Java-Objects.
signature of the java-method:
public NameValue[] process_context()
usage via php-java-bridge:
$nameValues = $activity->process_context();
So far I couldn't figure out a way how to iterate through all the
elements of the returned array in PHP. It seems not possible to access
the java.length property '$nameValues->length' nor will a
'foreach ($nameValues as $value) { echo "soemthing" }' work.
Are there any means available so I can determine how many elements are
in $nameValues?
I did see the provided examples and manual regarding the use of arrays
but I am not quite sury about it yet. ;(
Do I need to modify the native Java-Class so it provides another
java-interface(collection,ArrayList)?
Thx,
Peter

The above problem goes away when you distclean the php directory and remove all references to the old ext/java bridge and then re-build. I have compiled the bridge with TCP sockets directly into PHP 4.3.9 and compiled it into a CGI binary. As far as I can tell, the bridge works as it should.

Jost, Great, thankyou for this. I will test this out myself, and if reproducible I'll report it as a bug to apple.

The latest 1.4 seems to run okay if I switch off the compiler, 1.3 and earlier are no longer supported, the bridge uses features from 1.4 (exception chaining). However, when the JIT is enabled the scheme-demo (which is a pure java test) crashes after one hour. I will test against java 1.5 when it is available for OSX. Until then please run the server part on a different operating system, for example RHEL3 for PPC with IBM java 1.4.1, please see -> http://www-106.ibm.com/developerworks/java/jdk/linux/tested.html Jost ___________________________________________________________ Gesendet von Yahoo!

BUT, its is never that easy is it :-( ...
Now when trying to start apache I've had some problems :-
1) I was originally getting the following error before the dyld in 2)=20
below :-
java.lang.UnsatisfiedLinkError: no natcJavaBridge in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1517)
at java.lang.Runtime.loadLibrary0(Runtime.java:788)

So I made a softlink like so called libnatcJavaBridge.jnilib ->=20
libnatcJavaBridge.dylib (dylib being the OSX lib name [why, why, why])=20
and no longer get this error, good !
2) But I now I'm stuck on :-

Hi All, I've tried compiling the php-java-bridge (1.0.7 with a Makefile hack, and 1.0.8pre) on OSX and I run into the following error :- gcc -bundle -flat_namespace -undefined suppress -o .libs/java.so .libs/java.o .libs/java_bridge.o .libs/client.o .libs/proxyenv.o .libs/bind.o .libs/init_cfg.o ld: multiple definitions of symbol _java_globals .libs/java.o definition of _java_globals in section (__DATA,__common) .libs/java_bridge.o definition of _java_globals in section (__DATA,__common) .libs/client.o definition of _java_globals in section (__DATA,__common) make: *** [java.la] Error 1 Which (I think?) relates to the following from php_java.h :- #ifdef ZTS # define JG(v) TSRMG(java_globals_id, zend_java_globals *, v) #else # define JG(v) (java_globals.v) #endif Typically these issues are resolved on OSX by using extern, and no amount of my crappy ideas have worked so far :-). Can anyone give me any pointers ? CHEERS Paul |

[Please excuse the delay] > I"ve noticed that creating objects take much more time comparing to Java The jni/reflection/net overhead is currently somewhere between 2 .. 3.5. That means that PHP needs 2 (GNU) up to 3.5 (SUN) as much time to create a proxy through JNI. script1: [1 * CreateInstance + 1 * Invoke -> 0.0790050029755 sec] script2: [1 * PHP print + 4 * CreateInstance -> 0.458841085434 sec] I am not sure if your test is relevant. The PHP IO operation in script2 probably takes the most of the time. Both scripts probably include the times for the server connect sequence, which is currently quite expensive because the PHP/Java Bridge currently does not use persistent connections. So I think the above times are meaningless. Can you please run the benchmark in the tests.php5 folder and post the times? If you find that the interpreted(*) java method executes more than 2 or 3.5 times faster than the PHP method doing the same thing using JNI/Reflection calls, then we have to examine the network connection more closely: The performance also depends on the OS kernel and how fast it can push the bytes through the communication channel. Unix domain sockets are usually nearly as efficient as shared memory, but the throughput may vary from kernel to kernel; especially if your kernel is compiled with debug enabled, the delay becomes noticeable. Regards, Jost Boekemeier (*) The compiled java method is about 10 times faster than the interpreted java script. But that's normal behaviour, native machine code is always much faster than any interpreted script code. |

Hello Jost,
I'm writing about performance of php/java bridge. I've noticed that
creating objects take much more time comparing to Java. I understand
that some decrease of speed is natural, however this should not be so
visible. Look at below benchmarks:
- java
package example;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFCell;
class exampleclass {
public void exampleclass () {
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet();
HSSFRow row = sheet.createRow(0);
HSSFCell cell = row.createCell((short) 0);
}
}
from php: $spreadsheet = new java("example.exampleclass");
-----------------------------------------------------------------
time 0.0790050029755 sec
- php:
print "\n\nFrom PHP:\n";
$workbook = new java("org.apache.poi.hssf.usermodel.HSSFWorkbook");
$sheet = $workbook->createSheet();
$row = $sheet->createRow(0);
$cell = $row->createCell(0);
-----------------------------------------------------------------
time 0.458841085434 sec
Now, if you will create only php objects (without $spreadsheet = new
java("example.exampleclass")) then is even slower - about 0.55 sec. Is
this a normal behavior ?

> You will see that instead of special chars like "ąść" there is "?".
> UTF-8 should work ?
Yes, of course. See attached png. But note that your OS must support
UTF-8. For example:
bash-2.05b$ echo $LANG
de_DE.UTF-8
> $baseFont = new Java("com.lowagie.text.pdf.BaseFont");
> public static final boolean EMBEDDED = true;
Yes, I see the problem. The spec says that bean properties are examined
first. Which means that we have to call the method
BaseFont.isEmbedded(), which will return the protected variable
embedded. This is a) not what you want and b) does not work because
baseFont is a class, not an instance.
JSR 223 currently has the same problem.
I think it is necessary to check for a real variable first, only if that
fails we should call the property method. I check this against the
current spec and will decide when I am back from vacation in three
weeks.
BTW: Of course, the new Java(...BaseFont) code above should throw an
exception "class is abstract" instead of silently returning the class
instead of the instance. This is one of the problems the bridge has
inherited from the original php4 ext/java written by Sam Ruby. This
will change with the 2.x versions, when we switch to the JSR code.

> /usr/local/jdk1.5.0 > protocol.h:11:17: jni.h: No such file or directory Yes. This is a problem with the autoconf script: "find" does not following symlinks, so the incline does not find the include directories: PHP_EVAL_INCLINE(`for i in \`find $PHP_JAVA/include -type d -print\`; do echo -n "-I$i "; done`) I will fix this bug for the version 1.0.8, which will be available at the end of this month. Until then please invoke make as follows: make "CFLAGS=-I/usr/local/jdk1.5.0/include -I/usr/local/jdk1.5.0/include/linux" Regards, Jost Boekemeier ___________________________________________________________ Gesendet von Yahoo!

http://php-java-bridge.sourceforge.net/php-java-bridge_1.0.8-pre.tar.bz2 The following bugs were fixed: * AM_INIT_AUTOMAKE is now correctly called after AC_CONFIG_AUX_DIR (Autoconf 1.8, Fedora Core 3). * The space reserved for the auto-generated socketname (java.socketname not set) was two elements too small (due to a typo). This caused problems with some malloc implementations. New Features: * Zend's "thread safety", "ZTS", supported: It is now possible to run the PHP/Java Bridge in a pure threaded Web-Server, for example httpd 2.x with the worker MPM. -- Threaded servers are usually faster than servers which fork() childs, but they are also more insecure (no process barrier). However, since the web-server threads communicate with the single java process through a secure proxy, the server part of PHP/Java Bridge is protected even if a hacker takes over the web-server. * Linux' abstract namespace (see unix(7)) supported. This means that no socket files are created on this operating system (-> increased performance and security). * Linux' struct ucred (see unix(7)) supported: The UID and GID are passed to the server-side. Since the credentials are provided by the kernel, it is impossible to fake the auth. information. * Improved logging: module, time, level, message. Version 1.0.8 will be released at the end of this month. ___________________________________________________________ Gesendet von Yahoo!
