java.lang.IncompatibleClassChangeError: BasicDataSource

Hi,

I have a function return a DataSource, like:
DataSource setupDataSource(String dbName) {
  BasicDataSource ds = new BasicDataSource();
  ...
  return ds;
}

But, when I run the program, I got an exception:

Caused by: java.lang.IncompatibleClassChangeError: Class org.apache.commons.dbcp.BasicDataSource does not implement the requested interface javax.sql.DataSource

What wrong?


Yau.

Hello,

Apparently your code is compiled with another version as used at runtime.
