Can we use Entity bean(EJB3.0) in struts2.0?

[tyler piter]

Recently i take a try:

EntityBean: User.java
SessionBean: UserDao.java
Struts 2 Action: LoginAction.java

In LoginAction.java, i wrote:

User user=(User)UserDao.findUser(username,password);

Then, i got:

java.lang.ClassCastException: can't cast com.xx.xx.entity.User to com.xx.xx.entity.User.

How can i fix this?

Tyler,

Looks like a class-loading issue. Do you have duplicate (iedntical) classes in the WAR and EJB-JAR? If so, you need to eliminate that.

Thanks,

Reza,

Thanks!
it works now by follow your instruction. it seems jvm is confused by two same classes.

Tyler,

Just so you are aware, we talk about packaging and classloading for Java EE 5 applications in EJB 3 in Action. That being said, most readers seem to gloss over these important parts :-(.
