Will there be an updated version of the SCEA certification for JEE6?
Or are the changes with JEE6 not so important to make an update for SCEA necessary?
Why didn't Sun inform us as they promised last year?


We wanted to inform you that the full beta for the new Sun Java Programmer Plus Certification has been delayed to later in this year based on the results from initial beta testing and to align more closely with the upcoming release of JDK 7. We will get back in touch with you as soon as we have revised dates for the full beta test.



I tried to register today, but was informed that


All selections will be made by February 15, 2010.



Did anybody already receive a voucher for registration?
Have you already searched the JNDI-tree of your JBoss whether your bean was bound to the JNDI-tree?
And did you see any strange log messages when deploying your application to the server?
In this case, you can use an applet for selecting a folder on the client side, but you would have to code the tranfer of the individual files to the server yourself (commons-fileupload handles only the server-side of file-transfer as far as I know).

As far as I know it is not possible to upload several files or a complete folder in one turn via HTTP to the server.

Just call

This will invalidate the session on the server, therefore you don't have to care about the session cookie.

In the forEach-Tag, the list you are using is called

resultlist

, in the scriptlet-code the list you are using is called

returnlist

.
Are you sure you are using the same list in both cases?

That's true, therefore you should add

to your servlet code and

to your jsp-pages.

You are using relative paths in your JSP pages and servlets. I would suggest to use absolute paths (beginning with '/'), this should solve your problem.

For more specific validation concerns, you should perhaps consider to use a validation framework, e. g. Commons Validator.

If you really want to send a mail in a j2me-application, you can find a good introduction here.
But I still don't understand why you ask for jsp and servlets in the context of j2me. This only makes sense, when your j2me-application doesn't send the mail itself but calls a servlet which sends a mail via JavaMail. If this is the case, you really should consult the documentation Ulf mentioned.

Perhaps you have enabled Session-Cookies for Localhost, but not for the Remote-System in your browser-settings.
In your Source-Code, you do not have any statements for URL-Rewriting when cookies are disabled, so without session-cookies your application will lose the session every time the user clicks on a link.

If I were you, I would check how the HTML-page of the application is built and what parameters etc. are sent (by the way, did you URL-encode the URL you are calling in your application?).
In addition, you can check how the HTTP-communication is structured (e. g. with the LiveHTTPHeaders-Plugin in Firefox) when you call the target application in your web browser. This should give you insights about what parameters are sent and how they are transmitted to the target system.
Afterwards you should try to rebuild this structure manually with your HttpUrlConnection.

I think this API is replaced by SAAJ (SOAP with Attachments API for Java).
Have you set rtexprvalue to true in your tld?
