[JBoss Seam] - Disable converters for request parameters in the URL
by Basel
How can I disable auto convertion for request parameters that are of type Integer? I'm not sure but it looks like that Seam perform the conversion during the render response phase. In my component I have this:
| @RequestParameter("pn")
| @Out(value="pn", required=false)
| private Integer pageNumber = -1;

If that is not possible then I will have to change it to String, parse to int and catch any number format exception.

[JBoss Seam] - Re: Get / Post
by bambata
I specified already in the form: method="post" and then nothing is displayed in the url anymore when I click for example the submit button of the form. That works already and is not the problem I meant.
The problem is, when I call directly the method of a SFSB, which is annotated with @begin, by using pages.xml(through action-mapping)
then the page which gets displayed contains in the url the conversation-id and the session-id. And in that case no html-form was used.
So the configuration method="get" for this request must have happend internally somewhere, but I have no idea where exactly? How can I change this behaviour to method="post" ?

[JBoss Portal] - Re: OpenLDAP integration, just plan lost what to do after se
by jon_french＠fws.gov
I was asked by Daniel Valero to post my authentication solution, so here it is. Note that this solution will work against both LDAP servers which allow an anonymous bind and those that do not.
In the example login-config.xml below, I've shown how to set up the LoginModule in the case in which you need a "service" LDAP account in order to do an initial bind to the LDAP server before attempting to bind the given username and password.
Also note that I'm assuming that the user is handing me a username of an email.
Thanks to Scott Dawson of Unisys for putting me on the right track with this solution.

| * <li>searchBase - Use searchbase as the starting point for the LDAP search. [required]</li>

| * in order to perform the orginal email query. Leave blank for anonymous bind.</li>
| * <li>java.naming.security.credentials - the password used to bind to the ldap sesrver in order
