[Security & JAAS/JBoss] - Re: writing new LoginModul - unable to replace Principal ??
by info＠connext.co.za
Good Day,
There are two parts this:
1. Customise the Principal class
2. Retrieving the CallingPrincipal
1. Customise the Principal class
By default the LoginModules in JBoss make use of the SimplePrincipal class to denote principals in the system. It is easy to change the principal that the LoginModules create by setting the principalClass of the LDAPLoginModule in login-conf.xml
Example
<module-option name="principalClass">za.co.connext.jboss.LDAPPrincipal</module-option>
Just remember that the Principal class needs a constructor that takes the name of the user as a parameter.
2. Retrieving the CallingPrincipal
To enable to session context to retrieve the caller principal, the login module should save the information in the Subject.
The easiest way is to create a SimpleGroup with the name CallerPrincipal and add your principal object to it. Add the CallerPrincipal group to the principals collection of the subject. You should check the principals collection first to determine if the CallerPrincipal group was added by a LoginModule further up the chain. All of this should be done in the commit method of the LoginModule. In my implementations when using JBoss is to always to do a super.commit() before adding my custom logic in the commit method.
Hope this helps.

[JBoss jBPM] - Oracle exception deploying process
by mteira
Hello.
I'm trying to setup jBPM inside JBoss 4.0.4 GA. Once I've deployed the jbpm.ear (from CVS) I tried to deploy a process from the Graphic Designer. I'm getting an oracle exception while trying to identify older versions of the process trying to be deployed. What could be the cause? The select shown works correctly into an SQLPlus session.
Thanks.

[The Lizzard's corner] - Re: Are Open Source Software Tools Better than Commercial?
by jwenting
There doesn't have to be a problem, yet I do in my own experience notice that those OS tools that have (large) corporations behind them are generally far superior to those that don't.
Not just stability (will it be actively maintained in a few months and will there be support when and if I need it) but overall software quality and especially documentation quality are a lot better when there's corporate oversight rather than a bunch of hobbyists (who might well hold jobs writing other software) working together.
Because let's face it, maintenance programming and documentation writing are among our least favorite activities as programmers and when there's noone telling us to do it those activities tend to get sidestepped or rushed.
And there's the crucial fault with many OS projects that don't have corporate sponsorship where contributors are making a living writing that stuff for those sponsors (and are thus told to do that documentation and maintenance or loose that income), they tend to add a lot of shiny new features without serious commitment to stabilising what's already there (and documenting it).
Of course there are also poorly documented and maintained non-OS products, but the percentage is lower.
