In PHP/Java Bridge version 3.0.8: 

jar tvf c:/phptest.jar should display:
jl/phptest
META-INF/MANIFEST.MF

The PHP code may look like:
java_require("c:/phptest.jar");
$tf = new Java("jl.phptest");
$tf->test("hello");


In PHP/Java Bridge 3.1.0 you can convert the java
library into a PHP class and require it:

convert your java library /libraries to PHP code:
java -jar JavaBridge.jar --convert c:/php5/pear
c:/phptest.jar

The above command creates the PHP class jl_phptest in
c:/php5/pear/phptest/: 

<?php
/* ini_set("include_path", "c:/php5/pear"); */
require_once("phptest/jl_phptest.php");
$tf = new jl_phptest();
$result = $tf->test("hello");
echo "$result";
?>

Hi

[please excuse the delay]

great, thank you very much for these bug reports!


> > X_javabridge_redirect, referer:

Interesting. They probably have a hash function which
doesn't allow upper case and probably use this
function to also hash up headers from applications.

I have attached a patch called
php-java-bridge-3.0.8.3_to_3.0.8.4.patch, it should
fix this and the "ar" issue. I will apply it to 3.0.8
and 3.1.0, when I have some time.

I think the syntax is $tf =new Java("jl.phptest"); - dot instead of slash.

for example

[code]
package jl;


public class phptest{
/**
* A sample of a class that can work with PHP
* NB: The whole class must be public to work,
* and of course the methods you wish to call
* directly.
*
* Also note that from PHP the main method
* will not be called
*/

public String foo;

/**
* Takes a string and returns the result
* or a msg saying your string was empty
*/
public String test(String str) {
if(str.equals("")) {
str = "Your string was empty. ";
}
return str;
}

/**
* whatisfoo() simply returns the value of the variable foo.
*/
public String whatisfoo() {
return "foo is " + foo;
}


/**
* This is called if phptest is run from the command line with
* something like
* java phptest
* or
* java phptest hello there
*/
public static void main(String args[]) {
phptest p = new phptest();
if(args.length == 0) {
String arg = "";
System.out.println(p.test(arg));
}else{
for (int i=0; i < args.length; i++) {
String arg = args[i];
System.out.println(p.test(arg));
}
}
}
}
[/code]



if i write "java_require("c:/phptest.jar"); $tf =new
Java("jl/phptest");",,,it shows error.

how can i write it?
