Okay so i uploaded a new scenario to the site, but when i tried to load the scenario it came with an error. In Greenfoot on my computer it works fine, but here's the error: CacheEntry: updateAvailable=false,lastModified=Mon Sep 10 12:41:30 CEST 2012,length=283213 CacheEntry: updateAvailable=false,lastModified=Fri Aug 17 13:49:55 CEST 2012,length=143160 Attempting to reconnect to storage server greenfoot.util.GreenfootStorageException: Error connecting to storage server: Connection refused: connect at greenfoot.platforms.standalone.GreenfootUtilDelegateStandAlone.ensureStorageConnected(GreenfootUtilDelegateStandAlone.java:259) at greenfoot.platforms.standalone.GreenfootUtilDelegateStandAlone.getCurrentUserInfo(GreenfootUtilDelegateStandAlone.java:300) at greenfoot.util.GreenfootUtil.getCurrentUserInfo(GreenfootUtil.java:881) at greenfoot.UserInfo.getMyInfo(UserInfo.java:234) at TestWorld.setupWorld(TestWorld.java:27) at WombatWorld.<init>(WombatWorld.java:42) at TestWorld.<init>(TestWorld.java:19) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at greenfoot.export.GreenfootScenarioViewer.instantiateNewWorld(GreenfootScenarioViewer.java:323) at greenfoot.export.GreenfootScenarioViewer.init(GreenfootScenarioViewer.java:226) at com.sun.deploy.uitoolkit.impl.awt.AWTAppletAdapter.init(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) java.lang.NullPointerException at TestWorld.setupWorld(TestWorld.java:27) at WombatWorld.<init>(WombatWorld.java:42) at TestWorld.<init>(TestWorld.java:19) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at greenfoot.export.GreenfootScenarioViewer.instantiateNewWorld(GreenfootScenarioViewer.java:323) at greenfoot.export.GreenfootScenarioViewer.init(GreenfootScenarioViewer.java:226) at com.sun.deploy.uitoolkit.impl.awt.AWTAppletAdapter.init(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Java Plug-in 10.7.2.11 Using JRE version 1.7.0_07-b11 Java HotSpot(TM) Client VM User home directory = C:\Users\Zamoht So is there a problem in my code, my version of Java or does it have something to do with the site at the moment?

at TestWorld.setupWorld(TestWorld.java:27): String userName = UserInfo.getMyInfo().getUserName(); at WombatWorld.<init>(WombatWorld.java:42) setupWorld(xStart, yStart); at TestWorld.<init>(TestWorld.java:19) super(100, 100, 50, 50); I don't know if this adds any useful information.

So I tried to split line 27 into two bits like this: UserInfo user = UserInfo.getMyInfo(); String userName = user.getUserName(); And it says that "String userName = user.getUserName();" is a problem. So is anyone else experiencing problems with the getUserName() method??

Okay I fixed it by adding: 
UserInfo myInfo = UserInfo.getMyInfo();
if (myInfo.isStorageAvailable())
But I don't get any info. Is the storage down or is it just me having this problem?

I think the storage is down. My 'Private Messaging' scenario, which has been working fine for quite some time, has been showing my 'Not logged on' screen when I, in fact, have been logged on.

Good thank you.

The correct coding (above) is: 
if (UserInfo.isStorageAvailable())
{
    UserInfo myInfo = UserInfo.getMyInfo();
    // etc.
}
You should still be able to test (offline) the UserInfo coding of your scenarios.

We restarted the server yesterday and it seems the storage server didn't come back up - it should be fixed now. But yes, you should always check whether storage is available before trying to use it! :)
