How to run a Java .jar ?

[kimjarvis]

This question is about using java from PHP.

To validate an XML document against a schema I use Sun Multi Schema XML parser.

java -jar msv.jar doc.xsd doc.xml

I want to drive this process from PHP. I have the Java extensions installed and working however when I try to make an instance of the parser:

$msv = new Java("msv.jar");

Warning: java.lang.ClassNotFoundException: msv.jar

In the documentation for the Sun Multi Schema XML parser there are a number of ways the API can be called which I have tried with similar results.

How does the PHP extension know where to look for the java file?
Which of many java files should use to make an instance of the parser?

Is there another way of validating against a schema in PHP?

<?php

// Demonstrate XML validation against XSD schema
// The following verifies shiporder.xml document against schema shiporder.xsd
// using the Sun multi schema XML validator.

// The schema, XSD,DTD,TREX etc. is specified within the XML document itself.
// The msv.jar file containing the MSV methods must be in the path specified by
// java.class.path in php.ini

//	Create verifier factory
$factory = new Java("com.sun.msv.verifier.jarv.TheFactoryImpl");
//	Compile schema
$schema=$factory->compileSchema("c:\apache\htdocs\web\p06\shiporder.xsd");
//	Create a verifier
$verifier=$schema->newVerifier();
//	Verify XML document acording to its schema specification, Supress errors
@$rc=$verifier->verify("c:\apache\htdocs\web\p06\shiporder.xml");
if ($rc) 
{
	print "<p>The document is Valid</p>";
}
else
{
	print "<p>The document is Invalid</p>";

	// get the last exception
	$e = java_last_exception_get();

	if ($e)
	{
		// print error
		echo $e->toString(); 
	}
	else
	{
		echo $writer->toString();
		$writer->flush();
		$writer->close();
	}

	// clear the exception
	java_last_exception_clear();

}
