Thread: java code error

code=java
Hi guys!, I have this error while running ejb-3 application. What can I do to solve it.
DEPLOYMENTS IN ERROR:
Deployment "jboss.jca:name=MySq,service=DataSourceBinding " is in error due to
the following reason(s): ** NOT FOUND Depends on 'jboss.jca:name=MySq,service=Da
taSourceBinding' **
Deployment "<UNKNOWN jboss.j2ee:ear=PostOffice3.ear,jar=PostOffice3-ejb.jar,na
me=PostOffice3SB,service=EJB3>" is in error due to the following reason(s): ** U
NRESOLVED Demands 'persistence.unit:unitName=PostOffice3.ear/PostOffice3-ejb.jar
#PostOffice3-ejbPU' **

Just for the sake of guessing, curiosity and trial.

Deployment "jboss.jca:name=MySq,service=DataSourceBinding "

isn't it MySql instead of MySq? I'm assuming you had to type that, i am also assuming you are trying to connect to a database and the error itself is that is not finding the db, might be because of a typo.

Could be wrong, i'm posting for learning purposes lol.
