[Php-java-bridge-users] JasperReports problem

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

Hi,

I am using PHP-Java-bridge like this :
Report.java : is a java file containning a wrapper to JasperReports=20
notaly the following imports and method :
import net.sf.jasperreports.engine.*;
[...]
    public void setSubReport(String name, String compressed_xml) throws=20
JRException {
            InputStream stream =3D this.readCompressedXml(compressed_xml)=
;
            //compile into a JasperReport object
            JasperReport jasperReport =3D=20
JasperCompileManager.compileReport(stream);
            //add to subreports map
            _subreports.put(name, jasperReport);
    }

Now in php, I use Report.php :
$p =3D $GLOBALS['CONF']['SYS']['INCLUDE_PATH']['libraries'].'java/lib/';
$javapath =3D=20
$p.'commons-beanutils-1.5.jar;'.$p.'commons-collections-2.1.jar;'.
            $p.'commons-digester-1.7.jar;'.$p.'commons-logging-1.0.2.jar;=
'.
            $p.'commons-logging-api-1.0.2.jar;'.$p.'itext-1.3.1.jar;'.
            $p.'jasperreports-1.2.0.jar;'.$p.'jcommon-1.0.0.jar;'.
           =20
$p.'jfreechart-1.0.1.jar;'.$p.'poi-2.0.jar;'.$p.'xalan.jar;'.$p.'../repor=
t/Report.jar';
java_set_library_path($javapath);
try {
    $r =3D new Java('Report');
    $r->setSubReport($name, $row['sr_compressed_xml']);
} catch (JavaException $ex) {
    $trace =3D new java("java.io.ByteArrayOutputStream");
    $ex->printStackTrace(new java("java.io.PrintStream", $trace));
    die("<pre>java stack trace: $trace</pre>");
}

So now, this print the following error (snippet) :
Package not found : net.sf.jaspereports.engine line XX in master12345.jav=
a
(Note: the line JasperCompileManager.compileReport(stream); is the=20
bottom of the stacktrace).

This means that my Java class perfectly imports the package (because it=20
can call the JasperCompileManager.compile method) but the java classes=20
generated on the fly by Jasper (here named master12345) cannot use the=20
jars set in the javapath.

I digg into the source code and see that a new thread is opened for the=20
compilation : maybe this is the problem (related to the class loader in=20
php-java-bridge I think ?).
Plus, putting the jars into jdk/jre/lib/ext works, so this prove that it=20
should be a problem with the class loader.
Note that doing this (jars in lib/ext) is not really an option for a=20
production environment...

I hope you can help me to find a workaround for my situation;

best regards and keep on the good work,
chris
