[Php-java-bridge-users] sandbox

[Jay G. <yoe...@gm...>]

If I use the php-java bridge, will my Java code be run in the applet
sandbox?  I want to pull machine-specific info from my users so that i
can identify unique machines in a way not easily spoofed.

Also, this will prompt the user to allow the application, correct?

The java code (usually) runs in a J2EE application server and the PHP
scripts (usually) run in the HTTP server domain.  The PHP/Java Bridge
connects those two components.  I.e. it is a server technology, it
cannot run in a client browser or on a client machine and it cannot be
used as a replacement for java applets or ECMA script.

[Php-java-bridge-users] Arrays

[Michael P. D. <dob...@we...>]

Hi,

sorry I need help once more, because I don't get the answer for my question
even though I tried it for half a day

How can I access the fields of a returned array?

Example (here the number of the fields are known before execution, but in my
real application the number of the fields are known not until execution):

import java.util.*;
import java.sql.*;

public class javatest {

  public javatest() {
  }

  public static Object test1(String testvar) {
    Object testobj = null;
    testobj = new Object();
    testobj = testvar;
    return testobj;
  }

  public static Object[] test2(String testvar1, String testvar2) {
    Object[] testobj = null;
    testobj = new Object[2];
    testobj[0] = testvar1;
    testobj[1] = testvar2;
    return testobj;
  }
}


<?php
  $testvar = new Java('javatest');
  $testobj1 = $testvar->test1("TestAusgabe1");
  print $testobj1.' <br>';
  $testobj2 = $ testvar ->test2("TestAusgabe2.1"," TestAusgabe2.2"));
  print $testobj2[0].'  <br>';
  print $testobj2.'  <br>';
?>

Output:
TestAusgabe1
T
TestAusgabe2.2

So $testobj2 is not an array but a string which has the second value of
test2.

I have tried several things to access the first field of testobj2 but
without access. So I would be very happy if you have an advice what to do.

Many thanks in advance

Michael

Hi,

what you describe is a bug in the new 2.0 protocol.  Your second example
should create a PHP Array if run in PHP 4.  (It works correctly in PHP5,
see tests.php5 folder).

I am going to fix this asap.  In the meantime please use PHP 5 or use
the PHP/Java Bridge 1.0.8 for your tests.


Thank you very much for reporting this bug.

[Php-java-bridge-users] multidimensional arrays

[Michael P. D. <dob...@we...>]

Hi Jost,

sorry an email done again of me, but either I make something wrong or
perhaps I have found a little bug. However I hope you can help me ;-)

If java returns a multidimensional array, the bridge takes this as a nested
one-dimensional array. 

A small example:

public class javatest {

  public javatest() {
  }

  public static Object[][] test3(String testvar1, String testvar2, String
testvar3, String testvar4) {
    Object[][] testobj = null;
    testobj = new Object[2][2];
    testobj[0][0] = testvar1;
    testobj[0][1] = testvar2;
    testobj[1][0] = testvar3;
    testobj[1][1] = testvar4;
    return testobj;
  }
}


<?php
    $testvar = new Java('javatest');
    $testobj3 = $testvar->test3("Field 1,1","Field 1,2","Field 2,1","Field
2,2");
    print "testobj3: ";
    print_r($testobj3);
    print "<br>";
    for ($i = 0; $i < 2; $i++) {
      for ($j = 0; $j < 2; $j++) {
        print "$i,$j: " . $testobj3[$i][$j] .'  <br>';
      }
    }
    print "0,2: " . $testobj3[0][2] .'  <br>';
    $phptestobj = array(array("Field 1,1","Field 1,2"),
                        array("Field 2,1","Field 2,2"));
    print "phptestobj: ";
    print_r($phptestobj);
    print "<br>";
    for ($i = 0; $i < 2; $i++) {
      for ($j = 0; $j < 2; $j++) {
        print "$i,$j: " . $phptestobj[$i][$j] .'  <br>';
      }
    }
?>

Output:
testobj3: Array ( [0] => Array ( [0] => Field 1,1 [1] => Field 1,2 [2] =>
Array ( [0] => Field 2,1 [1] => Field 2,2 ) ) ) 
0,0: Field 1,1 
0,1: Field 1,2 
1,0: 
1,1: 
0,2: Array 
phptestobj: Array ( [0] => Array ( [0] => Field 1,1 [1] => Field 1,2 ) [1]
=> Array ( [0] => Field 2,1 [1] => Field 2,2 ) ) 
0,0: Field 1,1 
0,1: Field 1,2 
1,0: Field 2,1 
1,1: Field 2,2

Thanks and many Greetings

Michael
