Ill look into it but dont really understand it

is it in your class path?

the persisence xml file is in a folder called META-INF.

The other classes is in the folder called holdem.

Should i add under the ant library manager. And if so which libraries? persistence? persistence jpa2? postgreSQL JDBC Driver?

read the error you just posted. is that class in your classpath?

there is something called eclipselink (JPA 2.0) under the compile tab under libraries.

when I press add library. there is nothing called [org.apache.derby.jdbc.ClientDriver]

Should it be downloaded separately?

have imported import

java.lang.Object.*;

Have added some libraries and the first 2 lines seems to work TY catablance for your patience

But cant get this line to work
Player player = em.find( entityClass, IDnumber);

What should i write where it says entityClass?

It wont accept If i just write the name of the entityclass or null
