<p>My answer is still there, but accepting it has put it back to invisible in the approval workflow. I'll leave it there as a demo for those who fix this kind of issues. It'll re-appear soon when someone approves it again.</p> <p>If anybody wonders what I answered until it re-appears:</p> <div class="c-mt-2"> <div class="questions-article-body-121058915"> <div> <blockquote> <p>${tomcat.home}/lib ?</p></blockquote></div></div></div>

<p>Thanks Olaf. I saw your reply but for some reason it no more exists.</p> <p>[tomcat-home]/lib/ext had been removed from [tomcat-home]/conf/catalina.properties common.loader list in 7.4.1 GA2. Putting mysql connector to [tomcat-home]/lib worked fine. I guess it is possible to add a custom directory to catalina.properties common.loader list to have addidional jar files separated from tomcat's ones but for now [tomcat-home]/lib is Ok for me.</p>

<p>I have been using mysql-connector by adding the JAR file to global classpath [tomcat-home]/lib/ext.</p> <p>Liferay 7.4.1 has moved all JARs from [tomcat-home]/lib/ext to [tomcat-home]/webapps/ROOT/WEB-INF/lib and [tomcat-home]/lib/ext no more exists.</p> <p>Any suggestions where I should put my mysql-connector? Deploying it into osgi/modules causes <em>SQLException: Cannot load JDBC driver class 'com.mysql.cj.jdbc.Driver'</em> when a portlet tries to load the class.</p> <p>Cheers!</p>
