In a restricted environment I think it is best to use
the servlet/j2ee backend. You can deploy your
JavaBridge.war application without having admin
privileges and you can store all the java libraries
you need into your JavaBridge.war.

All java options except java.log_level are INI_SYSTEM,
that means only the administrator can set them.

Yes. But in earlier versions of the JavaBridge the
context classloader has had the wrong parent, this was
fixed in 3.0.7a. But I don't think this bug is
responsible for the current problem.

You can just type:

 phpize && ./configure --with-java=/opt/jdk1.5 && make

and then copy the modules/JavaBridge.war to

 cp modules/JavaBridge.war /opt/tomcat5.58/webapps

re-start tomcat and browse to:

 http://localhost:8080/JavaBridge/test.php

Or just download the J2EE binary
(http://prdownloads.sourceforge.net/php-java-bridge/php-java-bridge_3.0.7a_j2ee.zip?download),
which already contains a pre-compiled JavaBridge.war
for Solaris, Linux and Windows.

Does /opt/tomcat5.58/webapps/JavaBridge exist?  Which
error message do you see in the tomcat log file?

Hi,

just a maybe-silly question concerning setting the java.classpath in the=20
php.ini :
    Why can not I specify a directory instead of the jars ?

I ask because I have 12 jars to set in the cp, so this is bad to=20
maintains their hard-coded names in the php.ini

ex :
$> ls /home/christophe/workspace/www2/libraries/java/lib/
commons-beanutils-1.5.jar    commons-logging-api-1.0.2.jar =20
jcommon-1.0.0.jar     xalan.jar
commons-collections-2.1.jar  CVS                           =20
jfreechart-1.0.1.jar
commons-digester-1.7.jar     itext-1.3.1.jar                jxl.jar
commons-logging-1.0.2.jar    jasperreports-1.2.0.jar        poi-2.0.jar

$> cat /etc/php5/conf.d/java.ini

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
