I am using the below code in my REST service and it throws the error "java.lang.NoClassDefFoundError: com/intersys/jdbc/CacheDataSource] with root cause
java.lang.ClassNotFoundException: com.intersys.jdbc.CacheDataSource
"

Surprisingly when i am using the same code in a static main method its running perfectly.

package webapps.services.datamgmt.webapps;

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
