- Re: Using stateless beans generated by seam in stand 2007-07-13 - By JbossDing

Thanks for the reply and code example. But I thought the code generated by seam
-gen is not ejb (please refer to my above first message). I am very shallow on
seam so far. When I follow the seam tutorial of the Registration example,
everything is making sense, like you will code the session bean with annotation
@(protected) and entity bean with @(protected) What's more, there is a ejb-jar.xml
for deployment descriptor and each bean has remote methods that client can call
, for example method register().
However, if you look closely at the generated code as I posted above, for table
host, seam-gen generated 2 java files in src/Action folder, which I think
should be where session beans are. They HostHome.java and HostList.java. By
looking at those code closely, they do not have annotation @(protected) or
@(protected) What is more, I do not know what remote methods will execute CRUD
operations. For example, in HostHome.java, it has setHostId, getHostId, isWired
, wire, getDefinedInstance. If I need to update the records, what remote method
to call?
I am not very familiar with JPA. I thought the code you put in the last message
is for client to use JPA to query database. That is terrific. However, because
seam-gen generated data-access layer codes like session bean and entity beans,
I would like to be lazy and use the generated codes in client directly.
After a little reading of seam, it occurs to me that seam-gen generated data
-access code in src/Action folder is not suitable for direct call from a
standalone java application. Please correct me if I am wrong. I really need
some jboss seam guru to tell me if there is a way for standalone java client
(replacing jsf) to reuse seam-gen generated data-access codes. seam-gen is great
, but it's just too mysterious for me to us in a not so usual way.
Thanks for your attention nd help
