[ZOO-Discuss] Execute HelloWorldJava

[Gérald Fenoy]

Hi Daisuke,
you shouldn't have to specify anything in the [env] sectin of your ZOO main configuration file to make the HelloWorldJava working. Indeed ZOO Kernel shoudl set the CLASSPATH for you before loading and running your Java process (so your java class static function). Please, can you ensure that you well get the class located in the same directory that your ZOO Kernel and the ZOO Configuration File ?

Can you also ensure that the ZOO Kernel you used for your tests was well linked against the right Java Shared Library ? (using the ldd command and giving us the result here) Indeed, there can be an issue in the makefile generation.

The last test which can be usefull for us to help you can be to recompile your ZOO Kernel in debug mode (adding -DDEBUG to the Makefile CFLAGS) and giving us the apache log produced during your request.

Hope to hear from you soon,
best regards,
