[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

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

Just to say I digg into this problem all day and still find no solution.
What I do not understand is why a thread does not inherit the classpath=20
from the creating thread ?

or maybe the thread is not the problem (if so, please correct me because=20
I am really new to Java threads and javac called from a .java)

[Php-java-bridge-users] Dynamic ClassLoader problem

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

Hi,

> Just to say I digg into this problem all day and
> still find no solution.

Sorry for that. I assumed that this wasn't an
important issue, you've said that it works if you move
the jars to jre/lib/ext.


> What I do not understand is why a thread does not
> inherit the classpath 
> from the creating thread ?

JSP is a good example. The container doesn't want to
make the jsp classloader available to the webapp, so
it sets the thread context classloader to the parent
of the current classloader.

I don't know if and how your reporting engine handles
this, but in general applications may choose to ignore
our dynamic loader and load classes or create dynamic
proxies via the system classloader. If this happens,
the loaded classes or defined proxies cannot access
classes loaded via the dynamic loader.

So I think the best workaround is to install your
libraries in $JAVA_HOME/jre/lib/ext or to hard-code
the java.classpath in the php.ini file, for example:

java.classpath=/path/to/JavaBridge.jar:/path/to/lib1.jar:...

I have created a ticket for this problem, please see
PR1449780 for details
(http://sourceforge.net/tracker/index.php?func=detail&aid=1449780&group_id=117793&atid=679233)


Thank you very much for this bug report!

Re: [Php-java-bridge-users] Dynamic ClassLoader problem

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

Hi,

thanks for the detailed answer, I better understand my problem now.

Moving my jars into jre/lib/ext is not an option because you must be=20
root to do that (and I am not).
Hardcoding the java.classpath in the php.ini is maybe possible thanks to=20
a .htaccess so this is ok, I will watch for this today.

Concerning the isssue, here is a snippet from my report engine code in=20
order to provide more details:
this is the call to the compiler :

JRClassLoader.loadClassForName("org.eclipse.jdt.internal.compiler.Compile=
r");

Here is the JRClassLoader called method :

**
	*public* static *Class* loadClassForName(*String* className) *throws* *C=
lassNotFoundException*
	{
		*Class* clazz =3D *null*;

		*ClassLoader* classLoader =3D *Thread*.currentThread().getContextClassL=
oader();
		*if* (classLoader !=3D *null*)
		{
			*try*
			{
				clazz =3D *Class*.forName(className, *true*, classLoader);
			}
			*catch* (*ClassNotFoundException* e)
			{
				///if (log.isWarnEnabled())/
				///	log.warn("Failure using Thread.currentThread().getContextClassLoa=
der() in JRClassLoader class. Using JRClassLoader.class.getClassLoader() =
instead.");/
			}
		}

		*if* (clazz =3D=3D *null*)
		{
			classLoader =3D JRClassLoader.class.getClassLoader();
			*if* (classLoader =3D=3D *null*)
			{
				clazz =3D *Class*.forName(className);
			}
			*else*
			{
				clazz =3D *Class*.forName(className, *true*, classLoader);
			}
		}

		*return* clazz;
	}

Is the "*Thread*.currentThread().getContextClassLoader()" not the good me=
thod to obtain PHP-Java-bridge class loader ?

Again, thanks for the answer,

best regards,
chris

Hi,

> Why can not I specify a directory instead of the 
> jars ?

In some JVM (most java VM but not Mono) you can use
e.g.:

java -Djava.ext.dirs=/dir1:/dir2 -jar JavaBridge.jar 

But you cannot set this option in the php.ini file.
However, on windows the following could be used:

[java]
java.java="javaw -Djava.ext.dirs=..."


On Unix you could use a .sh wrapper, for example:

[java]
java.wrapper=/home/jostb/bin/startBackend.sh

And the startBackend.sh script could look like:
 #!/bin/sh

 java=$1; shift
 addOptions="-Djava.ext.dirs=..."
 exec $java $addOptions $*

I guess that's not the problem. The problem is, that javac does not 
inherit the classpath. i.e. just because the classes are available
to the compiler in it's runtime environment does not mean that he has 
access to the class definitions. (i.e. class files) - nor that he knows
how to find them.

I have done something similar once, and you definitely need to tell 
javac explicitly where to find the classes it needs.
If they are in /jre/lib/ext he will look there anyway, but it's not 
really a classloader problem - it's just that javac does not utilize
it's own classloader to look for classes - it uses the system classpath, 
plus classpaths he has been explicitly told to use.

Try System.setProperty to change the system classpath and try again, I 
guess that will help.

Thanks for the tip : I did not know that javac (i.e the one in=20
tools.jar) did not inherit the runtime classpath (but it seems logical=20
because, for example, I do not want my compilation be influenced by my=20
eclipse classpath).

I used the solution previously provided (i.e set java.classpath in the=20
php.ini) which seems to do the same thing (put the jars in the system=20
class loader).
I prefer to stay with this solution because it is clearly more simple=20
than to hook the JasperReports sources or than to set a system property=20
in an obscure part of the code (what I mean is that if other=20
applications use PHP-Java-bridge, it is simpler for them to know that=20
there already are some classes in the system classpath via php.ini).

Anyway, I will fill a bug on JasperReports to say that it will be good=20
to provide the necessarly used runtime jars to the javac compiler.

Thanks to take time to think on my problem.

Regards,
chris

Re: [Php-java-bridge-users] JasperReports problem

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

Just a quick reply : I watch the Jasper sources and they are already=20
using the context classloader.
As said by Jost Boekemeier, this is an issue of PHP-Java bridge not=20
setting correctly the context classloader before 3.0.8 (see bug PR1449780=
)

regards,
chris
