Why does liferay add librairies to my JSF portlet during deployment

[Eric Soucy, modifié il y a 10 années.]

Hello,
It seems that during the deployment process, Liferay adds the following libraries to my portlet (in the tomcat/webapp/myapp/web-inf/lib)
commons-logging.jar
log4j-extras.jar
log4j.jar
util-bridges.jar
util-taglib.jar
util-java.jar

Is it documented somewhere why this is being done ?

Thank you

These are default jars that all Liferay portlets require. You can add additional jar dependencies in liferay-plugin-package.properties file. It is best to use portal jars rather than your own versions so you don't run into class loader/versioning issues.
