[opencms-dev] help with jar file

[Pavel Peringer]

Hello

You wrote that you have created module "infrastructure" (lib and classes 
folder) in system/module
and I hope that you have created the module itself from the Module 
administration to :-)

After that you have module package only in VFS and the best way to 
deploy this module is from
Module administration again and on your module choose Export. The export 
path is
$CATALINA_HOME\webapps\opencms\WEB-INF\packages\modules
where you have zipped module folder with module version suffix.
This file is installable to any other Opencms by Module Import with HTTP.

But if you export module or not, allways when you are using "dynamic" 
things like jars and classes
it is necessarily <search.py?lg=en_cz&wd=necessarily> to restart/reload 
servlet context in order to let "know" Tomcat or any server
about you classes and jars, because publishing only does not do this.

Maybe you are using Eclipse with Tomcat plugin for *.java development 
and Eclipse is able
to exchange "old" version of class file to new one without Tomcat 
restart. And as I wrote
publishing VFS files does not do the same.

And as Jon right wrote the jar file MUST have same name as you module 
package.

Example
/system/modules/cz.test.www/lib/cz.test.www.jar
/system/modules/cz.test.www/classes/cz/test/www/Some.class

Then in your JSP use import cz.test.www.* and JSP should be working.
