[JCA/JBoss] - Re: Changinh connection state in CMP EJB
by vickyk
Adrian,
Considering the following scenario
Assuming that in MySQL Database we have a Reauth-Schema SCHEMA with the following tables:
1) Table0
2) Table1
3) Table2
Considering there are 3 users with the following username/password
1) user1/password1
2) user2/password2
3) user3/password3
Now user1,user2 and user3 can access Table0
user2 can only access Table1
user3 can only access Table2
I think I can use GRANT feature in MySql I have yet not tried this ?..
Considering the following flow in the application code
1) Create a connection Pool for user1/password1.
2) Get the connection from the pool which is created in the Step1.
3) Fire a DML command on the Table0.
4) Now, try to fire the command on the Table1.
The Step4 should now get executed as Table1 can't be accessed by user1 identity. The work around should be to change the identity associated with the connection when taken from the Connection Pool for the Step 4.
This is what I understand from the Re-Authentication feature from the EIS(MySql side) , however I am not sure of how to make such settings.
I am trying to understand the Reauthentication feature at EIS side, is this how it works?

[JBoss Seam] - rich:tree with a simple s:link?!
by mugwump
I'm trying to get the most naive implementation of a list with a a seam-link to run:
| <rich:tree rendered="#{not empty containerHome.instance.children}"
| style="width:300px"
| value="#{containerHome.childTree}"
| var="child"
| nodeFace="#{child.type}"
| switchType="client">
| <rich:treeNode type="child">
| <s:link view="/redsys/structure/#{empty from ? 'Container' : from}.xhtml" value="#{child.name}" id="container">
| <f:param name="containerId" value="#{child.id}"/>
| </s:link>
| </rich:treeNode>
| </rich:tree>
|
The link is rendered correctly, however it does not work. It looks like the click-event gets captured by the tree-select-javascript. Is there a simple way of making such a seam-link to work in a tree?!
cheers
