[Php-java-bridge-users] Problems accessing classes in JAR file

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

I've never done any Java programming before, so I may be missing 
something fairly obvious here.

I want to use the Saxon java classes to process XML 2.0 Xpaths via PHP.

So I've done:

     java_require(SAXON_DIR."saxon9he.jar");

(where SAXON_DIR is predefined). I then find that I can directly access 
the Saxon classes via PHP , such as:

    $config = new java("net.sf.saxon.Configuration");

So all OK so far!

However, for efficiency reason I don't want to make multiple PHP calls 
to java to do the Xpath processing. So I want to create my own java 
class which does all the necessary Saxon processing and can be accessed 
with one PHP call.

I've created this class, built a JAR file (SaxonXPath.jar) and verified 
that it works via a standalone java program, run as:

       java -cp .:SaxonXPath.jar:saxon9he.jar TestProg

So I now want to run this via PHP/java-bridge and have done:

             java_require(SAXON_DIR."saxon9he.jar");
             java_require(SAXON_DIR."SaxonXPath.jar");

I put these into a catch/try block, so I have verified that they are 
successfully loaded. However, when I try and instantiate my class in 
"SaxonXPath.jar" I get the error:

     java.lang.ClassNotFoundException: Could not find 
com.legatio.xml.SaxonXPath in java_require() path. Please check the path 
and the SEL and File permissions.

I can still access the "saxon9he.jar" classes directly and I've 
double-checked that I'm using the correct path to my own class.

I tried setting "[java]" "java.classpath" in the php.ini file to the jar 
files directory location, but this made no difference.

Does anyone have any idea of what I might be doing wrong here?
