Getting Tomcat error- any ideas?

Im on a Uni tomcat server and am getting this error "The requested resource (/05ics42/servlet/SessionServlet) is not available."
I cant change the actual tomcat settings but i dont think its that, all the other students dont have this problem so im thinking the tomcat settings are fine. Im under the impression that it may actually be something in my servlet.

Any ideas? Thanks for any help Gurus :D

<servlet-class>SessionServlet</servlet-class>Your servlet class MUST have a package. Specify a package for the servlet class, recompile it and place it with the proper directory structure corresponding to the package under WEb-INF/classes for your web application. Then specify the <servlet-class> tag with the fully qualified servlet class name.
It should solve your problem.

Flashbuilder 4 Upgrade from Flex 3 getting following errors any idea

Hi:
I'm getting the following 2 errors when I try to compile a swf from Flex 3 to FB4
Any ideas and how to get around this
1) 1061: Call to a possibly undefined method addChild through a reference with static type mx.core:INavigatorContent
      this is the AS call
        app.dashboardstack.selectedCild.addChild(panel);
2) 1118: Implicit coercion of a value with static type mx.core.INavigatorContent to a possibly unrelated type
             mx.core.Container
        var subjectObject:Container = accordion.selectedChild;
Thanks, Mike

You need to read this, http://www.adobe.com/devnet/flex/articles/flex3and4_differences.html and a couple of other related articles in the Flex Developer Center.

Tomcat error, any idea?

Hi,
I am using tomcat container for jsp pages. The problem is that the moment I start tomcat I get following error. I did not even go to browser and has not even loaded any jsp page. this is just initial tomcat startup error. What could be the reason?

I ran into the same snag. Apparently, tomcat v4.1.x has some dependencies on the example web applications deployed in the webapps directory, and removing them causes this silent failure to occur. I fixed the problem by restoring the example webapps, but apparently this can be avoided by using the $TOMCAT_HOME/conf/server-noexamples.xml.config file.
Good luck!

I cant get into itunes producer keep getting an error my username and password is incorrect. i have made a new one all good still same error any ideas?

I'm having a very similar problem.
I'm based in the U.K. and am trying to publish an iBook through the iTunes bookstore. I have made my book in iBooks author 2.0. My iTunes is up to date.
When I try and publish the iBook I have passed and ticked the Pre Publish Check; and the Create Account, but when I try and download iTunes Producer through iTunes Connect I'm told "Your Apple ID does not have permission to access iTunes Content."
When I try and re-set my iTunes Store account I'm told "The iTunes Store Account has already applied to distribute content on the iBookstore." Of course it has I just did that.
If I try and sign in to iTunes Connect through the Publishing pane I'm told "Your ID or Password was entered incorrectly." Even though I've just used it to sign into iTunes (and here), so my password and Apple ID work fine elsewhere.
Is my access to the iTunes Connect being delayed while my submission is processed, i.e. the processing of my tax and account details? Or am I stuck in a loop?
If this is still processing (I started this 20 hours ago) I assume that I have to submit the book itself when I can download iTunes Producer at a later date, as I haven't submitted the book yet?
I emailed the problem to iTunes Store and was refered to [email protected], only for them to say they don't read or reply to emails sent to that address??????
I'm not sure which part of the process I've reached - if any. I feel I'm in limbo. I have an iBook ready to go - but where is Apple?
Any help would be most welcome.

Have you tried to export different images as a test to see if it is related to the one you are getting the error on? Also try to export to a different folder other then the Desktop, again to see if the problem is connected to that folder.
Another thing to do is run the Aperture Library First Aid on the library. Hold the option and command keys down while you start Aperture. First run the Permission Repair and see if that helps. If not quit Aperture and restart and run the Library Repair and try.
Post back if you still have problems

if you use a hdmi to dvi converter then you only get picture and not audio because dvi don't carry audio same with vga

Standard troubleshooting steps in order are as follows - checking after each one to see if the problem is resolved:
Power your iPad off and on.
A reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
Restore your iPad with iTunes from your iPad's backup.
Restore your iPad with iTunes as a new iPad or not from your iPad's backup.
