Hi,
I am having some trouble setting the classpath for the hosted JVM.
I understand there are two options here: via Classpath or by doing it
explicitly via a manual java_jvm_attach().
The latter does not seem to be available as, even right after starting
the server, the JVM appears as already created.
So I need to set the classpath env variable.
I assume this only needs to be set in the terminal session used to
launch the virtuoso process, so I tried the following:
set CLASSPATH=/vdb/virt-jvm-py-6.1.2/java/virt-java-tests.jar;%CLASSPATH%
virtuoso-javavm-t -f
No luck.
The classes in the virt-java-tests.jar are not available (
NoClassDefFoundError ), but JRE/JDK classes are, and work fine. So,
for example, I can do this:
import_jar (null, vector ('java.lang.System'));
select java_lang_System::getProperty('java.vm.name'); -- works OK
select java_lang_System::getProperty('java.class.path'); -- shows me
that only '.' is in the classpath
* Do I have to export the env variable to the system?
* Once I get past that issue, I will need to pass some parameters to
the JVM. I understand java_jvm_attach() allows for this. But can I do
it via env vars or ini, for example?
* A bit off topic... what is the recommended way to setup the jdbc
connection from a hosted JVM? Is there a "tighter" route ( a la PHP
hosting ).
This is really really cool btw!
