SQLException堆栈跟踪

Question

So I got sort of strange situation. I have Spring webapp and in it I have JNDI datasource that I have defined in tomcat's server.xml to connect to mysql database I have mysql-connector-java 5.1.2 in my Maven pom.

Application works when I start it from localhost, but when I deploy it to remote tomcat it is not getting the call to the database.

This Exception occurs :

Couldnt execute sql CALL shareholders_company_list(?)
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Unable to create correct SQLException class instance, error class/codes may be incorrect. Reason:

** BEGIN NESTED EXCEPTION **

java.sql.SQLException
MESSAGE: Can't instantiate required class due to java.lang.ClassNotFoundException: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException

STACKTRACE:

java.sql.SQLException: Can't instantiate required class due to java.lang.ClassNotFoundException: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException

Is there away to avoid this ClassNotFoundException, so that I can get full stack trace, since it seems that explicit error why this happens is in MySQLNonTransientConnectionException, and I can't seem to reach it.

Answer 1

在tomcat\\lib下mysql-connector-java-latestVersion.jar所需版本（如果没有优先级，则为最新版本）
