Re: [Exist-open] How to make a jar XQuery module

As far as I am aware, you would only be able to use a JAR file with Modules written in Java, not in XQuery.

Although I may be wrong...

Subject: [Exist-open] How to make a jar XQuery module
 

Hi, 

I have developed an XQuery application that uses some XQuery modules (also develop for me). Seeing the documentation giving by eXist (http://www.exist-db.org/xquery.html) I could see that 4 ways can be used to work with modules in eXist:
    - As an URI
    - As a collection in the database
    - As a jar file, (Copy-paste --> If the XQuery module is part of a Java application, it might also be an option, to pack the module into a Java archive (.jar file) along with the Java classes)
    - As a Java class, if the module is itself implemented in Java

At this moment, my XQuery modules are stored as a collection in the database and they work perfectly, but I would like to make a jar file. I  have 4 four modules with plenty of functions:
    - first.xqm (that uses second.xqm)
    - second.xqm (that uses third.xqm and fourth.xqm)
    - third.xqm
    - fourth.xqm

 From your documentation (http://www.exist-db.org/xquery.html#javamods) eXist supports two types of XQuery-based library modules:
    - External Modules, which are themselves written in                XQuery, but how to use it?
    - Internal Modules, which are implemented in Java.                

but I don't know how to make the jar file, wondering
    - is it necessary to develop a Java file for each XQuery module that integrates modules? 
    - is it only necessary to develop only a Java file as EchoFunction (eXist/extensions/modules/src/org/exist/xquery/modules/example) that in some way you can specify where my XQuery modules are and which are the funtions??
    - In the eXist example: import module namespace status='http://exist-db.org/xquery/admin-interface/status' at 'resource:org/exist/xquery/lib/test.xqm';  where test.xqm is?

I could not find any example about this (if it is, apologies for the message)    

Any idea helps me. 

Thanks, Luis
