LispWorks Java and MacOS

I am running LispWorks 7.1 on MacOS 10.11.6. 
I am trying to initialize the java interface with (init-java-interface :jvm-library-path t) , but I get an error saying that I need to use the legacy version 6 of Java. Following this message, LispWorks exits. 
I have Java 8 Update 161 installed.  

What do I need to do?
- Pass some parameters to init-java-interface to allow for the current Java version to be used?
- Backtrack to Java 6?
- Other options?

Thanks

Bruno

Re: LispWorks Java and MacOS

After the initial success, I slowed down very quickly. 
I am not very familiar with Java, so I am facing a steep learning curve. 
So most of what follows might be a very basic set of questions. 

I want to interface with ActiveMQ. I built a STOMP producer/customer a couple of years ago, and ti was easy, but I need this time to use openwire. I looked at the openwire specs, and would rather use something that already works, such as the Java JMS and org.apache.ActiveMQ. 

I downloaded the last version of the Java SE SDK (9.0.4), and realized that the JMS seems to be part of EE. As far as I can see, EE does not  come with a VM. 

So here is a set of naive questions:
- After initializing the VM with init-java-interface, are we limited to the classes already defined in the VM (using import-java-class-definitions) ?
- Is there a way to load jar files in the initialized VM using lisp?

Re: LispWorks Java and MacOS

EE is a big spec implemented by application servers (such as WildFly). If you only want JMS, pick an implementation (such as ActiveMQ) and use it without caring about EE.

I don't know the LispWorks interface to Java, but I see a :java-class-path parameter: that's where you can place additional libraries (jar files) to be picked up by the JVM. Expect a bit of pain with the dependencies because nowadays projects use automatic dependency resolution (similar to ASDF + Quicklisp), nobody manually downloads jars anymore, and projects are structured keeping that into account (read: lots of tiny and not so tiny dependencies).

Re: LispWorks Java and MacOS

The -classpath argument to the JVM is a list of directories (of .class files) and/or .jar files and/or wildcard directory entries (e.g. foo/*) containing jar files. The list is separated by a system-dependent character, which is ':' on *nix and ';' on Windows.

I'm not sure if all of that applies to a JVM which is not instantiated through its "java" command, but looking at that (format nil "~S:~S" lispcalls class-paths) in your code I'm pretty sure class-paths can be something like "lib/foo.jar:lib/bar.jar:..."

Thanks Alessio,

As far as I know, and again I am new to the Java lisp integration, the :java-class-path points to "etc/lispcalls.jar”, which is used for Java to Lisp calls.

I do not know if it is possible to point to a directory of jar files for searching classes, and I do not think that the :jin-env-finder parameter is what is needed.
