You have to load image in File object before using it
like this
File file = new File("c:\\files\\image.png");
Image image = new Image(file.toURI().toString());

Play framework : UnexpectedException: While applying class play.classloading.enhancers.LVEnhancer

What's wrong?

Thank you very much for your answer.
I found the solution : I didn't have the version of javassist that didin't match with the project files.
With the Playframework 1.3, javassist-3.20xxx didn't work. I had to install javassist-3.19xxx

Error during sbt execution: java.lang.ExceptionInInitializerError
can any one help how shall i proceed.

It is pretty much clear if you read your (own) stack trace carefully:
Caused by: java.lang.RuntimeException: BAD URI: file://f:/Play/activator-1.2.10-minimal
You are trying to access a file via an URI which is malformed.
A correct URI would be either file:/f:/Play/activator-1.2.10-minimal or file:///f:/Play/activator-1.2.10-minimal (see also this answer).

Amit... probably he dont know (how to) "play" ....
check this up...

Google App add contact error?

In my GAE app there is the following line :
ContactsService myService=new ContactsService("app-name");
It compiled fine, but when run, it cause the following error :

I've included guava-r09.jar, so it has the "ImmutableSet", if I don't included guava-r09.jar, it will say :
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableSet
What should I do ?

I found out why : don't need to include google-collect-*.jar, source of error.

Anyone using grailsflow in its Plug-in or Demo version?

Grailsflow seems to be broken (as of Jan 2010) with Grails 1.2 or above, in both 'demo' and the plug-in flavours. Is there anyone out there using it? Have moved code out of the plug-in into my BootStrap.groovy, so the app will start.
#see jcatalog forum post
But still need to work around or resolve the error in all views.
See stack trace below:

The error is because it is unable to load the resource bundles for the messages. I moved them out into the default messages.properties file and modified the GSP's accordingly. Now the application starts fine and I can access the pages fine but there are still some errors as below..
