  • Cannot load JDBC driver class 'com.mysql.jdbc.Driver'

    #1

    Hi all

    I finally managed to get past the no openspecime.properties file issue.

    Know though I get the following error in tomcat log. Can anyone help please:

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘de-liquibase’ defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is liquibase.exception.DatabaseException: java.sql.SQLException: Cannot load JDBC driver class ‘com.mysql.jdbc.Driver’

    Hello,

    Based on the error message I assume you did not deploy the mysql connector (https://dev.mysql.com/downloads/connector/j/). You have basically two options
    (a): deploy it directly with openspecimen - copy the jar file into the WEB-INF/lib folder within the openspecimen exploded web application folder
    (b): add mysql connector as a common lib in tomcat
