NoClassDefFoundError when starting Apache w/ PHP-Java-Bridge

pbmods

Heya.

I just installed PHP-Java-Bridge on my system, but I'm having a hard time getting it to stop crashing Apache.

When I activate the 'Java.so' module in php.ini, I get the following error in my Apache logfile:

As I understand it, this error means that there are no '.class' files in that path. Is this correct? What's with that weird path, 'php/java/bridge/Standalone'? Is this possibly getting mangled somewhere?

I'm posting this both in the Java and PHP forum because I'd like to get input on both sides of the issue. I suspect that it's a configuration issue with PHP-Java Bridge, but I can't be sure because the documentation for it is horribly confusing.

Thanks for your time.

I suspect a classpath issue somewhere; what does the php documentation say?
Does that php java.so want to start the entire jvm? Is there a .jar file that contains
the Standalone class? Is that .jar part of the classpath? Questions. questions ...

kind regards,

Heya, Jos.

Thanks for your response.

I ran the issue by a couple of people, and we collectively remembered that Java class packages are stored in a hierarchal format on the filesystem (i.e., Java was trying to require 'php.java.bridge.Standalone'.

After copying the relevant classes from the php-java-bridge source directory and modifying php.ini, I have made the error go away.

Now, Apache crashes without giving any kind of error message.

But now I'm pretty sure this is not a Java-related issue.

Apache likes doing that if you can't recite that sloppy documentation from cover
to cover (preferably in Greek, all backwards while doing the secret Apache dance):
it silently crashes right in front of your own eyes before you'll know it.
It's a feature ;-)

kind regards,

Haha yes. Though this time, it is definitely not Apache's fault.

I know, I know; it's up there with 'safe User input', but really!
