Define class loader for web application with Liberty - spring-boot

Question

I have an application Rest service it is a war I want to deploy it in Liberty profile.Currently I am packaging the app along with all spring jar inside war.
But we want to create a shared library and move all those jar's into shared lib and reference that shared library using class loader from application.
server.xml
<application location ="restapp-1.0.0-SNAPSHOT.war" context-root="/myrestapp/mytestapp">
<classloader commonLibraryRef="global"/>
</application>
<library id="global">
<fileset includes="*.jar" dir="${server.config.dir}/lib/global"></fileset>
</library>
Also I have placed all the jar dependencies under server/config/lib/global.
I am having below entries in my ibm-web-ext.xml which is in webapp/WEB-INF/
<web-ext
xmlns="http://websphere.ibm.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-ext_1_0.xsd"
version="1.0">
<reload-interval value="3"/>
<context-root uri="/myrestapp/mytestapp" />
<enable-directory-browsing value="false"/>
<enable-file-serving value="true"/>
<enable-reloading value="true"/>
<enable-serving-servlets-by-class-name value="false" />
</web-ext>
Same config is working fine if I bundle all the jar's as part of WAR and place the war in dropins folder. But Sharedlibrary configuration is not working.

Answer 1

You can define a shared library for your application in WebSphere Liberty by putting the following configuration in the server.xml:
<library id="springLib">
<fileset dir="${server.config.dir}/libs/spring/" includes="*.jar"/>
</library>
<application location ="restService.war">
<classloader commonLibraryRef="springLib"/>
</application>
With this configuration, code in the restService.war will be able to load classes from the springLib shared library.
