jasperreports 上的远程 MYSQL 错误：未找到 com.mysql.jdbc.Driver

Question

I am trying to use a remote MYSQL source for my jasperserver. The connection is good and does not throw an error. However, when I try to make a report in jasperstudio, I get the following error

Error log:

I absolutely have the driver class mysql-connector-java-5.1.26-bin.jar in /opt/jasperreports-server-cp-5.5.0/lib too.

I also have the same connector.jar in the class path /opt/jasperreports-server-cp-5.5.0/webapps/jasperserver/WEB-INF/lib ... still nothing.

I'm not sure what the problem is...any help would be appreciated! Thanks!

Answer 1

SOLVED IT!!

I had to add the driver to the class path in jasper suite too!

Answer 2

sudo dnf install mysql-connector-java
updatedb
locate mysql-connector-java.jar

Then simply add the absolute path in your JasperSoft "Driver Classpath" tab.
