Re: [Php-java-bridge-users] NoClassDefFound error - how do I resolve?

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

Hi again.

I am replying to my own question post since a friend of mine helped  
me track down my NoClassDefFound problem (thanks Russell).

The error is in the java_require's at the beginning of my code.  I  
needed to use the format java_require(JAR1;JAR2;JAR3;JAR4); instead  
of separating the requires.  There is cross calling in the classes in  
the 4 libraries I use so they must all be brought into the same  
memory space.  See the following reference for full details:

http://php-java-bridge.sourceforge.net/documentation/PHP-API/html/ 
java_8c.html#doc23

I read this before, but it didn't rally gel in my brain until I was  
reminded of how libraries are cached by the back-end loader.
