[JBoss-user] [JBoss Seam] - Re: Entity Manager null
Hi James
I have changed the servlet mapping to be /servlet/ and added the filter
code to the web.xml file in my application as per your code snippet.
I am able to call the doPost method in my servlet which in turn calls
|
| EnvelopeUploadBean uploader = null;
| try
| {
| uploader = new EnvelopeUploadBean();
| }
| catch (Exception e)
| {
| e.printStackTrace();
| }
|
| String result = uploader.uploadEnvelope(inputStream);
|
|
This then runs everything in the *bean* correctly.
However - I am still unable to get the EntityManager (it is still null when I
am trying to persist the data to my database)
I have searched the reference docs for info on the SeamServletFilter and how to
use it with very little success.
If possible, could you explain, or point me in right dicetion as to how to
involk the filter and make it possible for me to use the EntityManager
Thanks
Neil

I'd got this porblems as well, while trying to inject the Entitymanager, my
Problem was, that the bean accessing the EntityManager wasn't an ejb3
sessionbean. So this solved my problem:
@Stateless
| public class foo{
| @PersistentContext EntityManager em
| ...
| }
after making the Bean a Sessionbean the EntityManager was injected correctly

I have the following
| @Stateless
| @Name(envelopeUpload)
| public class EnvelopeUploadBean implements EnvelopeUpload, Serializable
| {
|
| @PersistenceContext
| private EntityManager em;
|
| .
|
|
I have even tried with the unit name of the context ( the DS) and that doesnt
work either.
The other Objects that I am injecting are working fine. I can get the Object
the I am going to persist and set all the vars.

did you set up the datasource the right way?

I would think so. All the other functions of retrieving data from the database and displaying it in datatables are working fine in my web app. It is just the bean that is called by the servlet, where the em is null and I cant seem to instantiate it.

[JBoss-user] [JBoss Seam] - Re: Entity Manager null
Make sure that you have the seam servlet filter invoked before your filter and that you pass it conversationid as a parameter. See the documentation on the SeamServletFilter. the entry in the web.xml is this. | filter | filter-nameSeam Servlet Filter/filter-name | filter-classorg.jboss.seam.servlet.SeamServletFilter/filter-class | /filter | | filter-mapping | filter-nameSeam Servlet Filter/filter-name | url-pattern/servlet/*/url-pattern | /filter-mapping Hope this resolves your issue, James View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3927705#3927705 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3927705 --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
