Deferred binding failed error - gwt

I am unable to solve this exception. I am trying to implement the cell table in gwt which is in GWT showcase. Below is my exception.

I am getting here in the below part..
interface DatabaseConstants extends Constants {
String[] contactDatabaseCategories();
}
DatabaseConstants constants = GWT.create(DatabaseConstants.class);

This could be a few things first check you have a DatabaseConstants.properties file to store the values, next ensure that the key contactDatabaseCategories exists and has a comma separated list of values. Also might have to create the constants as a stand alone class
UPDATE
Move the interface to it's own .java file
Create a text file called DatabaseConstants.properties at the same level as the .java file
within that you can put
contactDatabaseCategories=Category1,Category2
That should stop that error and provide you a value for more information take a look at constants

Groovy - use Grape to download documentation and sources

It's possible to use Grape to download a dependency from Maven central:
#Grab(group='org.apache.commons', module='commons-lang3', version='3.4')
Specifying a type of jar within the Grab annotation does the same thing:
#Grab(group='org.apache.commons', module='commons-lang3', version='3.4', type='jar')
and according to the javadoc, the value of type can also be javadoc and sources, however trying the following in IntelliJ:
#Grab(group='org.apache.commons', module='commons-lang3', version='3.4', type = 'sources')
results in:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

Eclipse gives a similar error. So is there a a way to use Grape to download sources/javadoc when editing a groovy script in an IDE?
The doc you link to also mentions the possibility of using the classifier attribute, which seems to work better (Grape will indeed grab the corresponding jars):
#Grab(group='org.apache.commons', module='commons-lang3', version='3.4', classifier='sources')
However, it looks like Grape support in Idea is incomplete. In order for Idea to use the grabbed packages, you need to place your cursor on the #Grab annotation, press alt-enter and grab the artifacts manually. You could then copy them to module libraries from the projet structure's settings. That seems to do it for me, although I also feel it defies the whole point of using Grape...

NetBeans 7.4 not creating jar files properly

I am developing a project for a Java Enterprise Applications class. I have an application with an ejb module that has "facade" classes from a class library that connects to a simple Twitter-like database. All the logic is working fine, however, when I add the remote beans for the facade and try to run it, the application crashes with the stack trace included at the end.
Looking throught the GlassFish output screen, I found the following warnings:
WARNING: ACDEPL112: The following extensions or libraries are referenced from the manifest of C:\Users[project_path]\Questions\dist\gfdeploy\Questions\QuestionClient.jar but were not found where indicated: QuestionLib.jar ; ignoring and continuing
INFO: ACDEPL103: Java Web Start services started for the app client Questions/QuestionClient.jar (contextRoot: /Questions/QuestionClient)
INFO: Questions was successfully deployed in 3,097 milliseconds.
WARNING: The collection of metamodel [EntityType] types is empty. Model classes may not have been found during entity search for Java SE and some Java EE container managed persistence units. Please verify that your entity classes are referenced in persistence.xml using either elements or a global false element. The lookup on [class com.problemSet3.db.Questions] will return null.
WARNING: EJB5184:A system exception occurred during an invocation on EJB QuestionsFacade, method: public java.util.List com.problemSet3.db.AbstractFacade.findAll()
When I checked the path, I found that the .jar file mentioned exists where it should, but it is instead named QuestionLib_jar and it is a folder with all the contents of the jar file. This files are being generated by NetBeans, I don't know how the jar files are being compiled to folders instead of actual jars.
How can I fix this?

Java Result: 1
Well, after a painful night and morning I finally solved it. The persistence.xml file that was being used by the ejb module had this line:
<exclude-unlisted-classes>false</exclude-unlisted-classes>
I went into the properties and made it include each class manually, so now it looks like this:
<class>com.problemSet3.db.Answers</class>
<class>com.problemSet3.db.Questions</class>
<class>com.problemSet3.db.Users</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
plus the other generated code. I still get the warning on GlassFish, but no exceptions are thrown.

Jar file containing NetSNMPAction

I am running an application that uses classes generated from a WSDL using wsimport. As I've encountered NoClassDefFoundError I've added the appropriate jar files to the Eclipse build.
However I'm stymied now with a missing interface:

While I'm looking for the Jar file that implements this interface. I'm more troubled by the number and type of missing classes that the generated code seems to require. One missing class was the Java Python interpreter (which I resolved by adding . I'm wondering if I'm heading into a place I don't want to be and should review my Eclipse project. I'm not sure where to start doing that so I'm asking for some advice on how to keep from going down the road to jar hell.
Update: I've changed from using wsdlimport artifacts to using wsdl2java and it's generated code. It's working but I'd still like some advice for the future.

Had the same thing here. Resolved it by replacing the Image (<img>) with a Label (<div>) and gave it a background-image style property. Adding and removing the Label from the dom does not throw the exception in IE.
I am also got this exception, i resolved this. In my case i am removing image from parent while doing this in IE8 GWT runing a thread for changing the proeprites on the image that time it is throwing exception. so instead of removing i just made it hidden, it is resolved

GWT serialization exception

I have a simple service method which returns ArrayList. However when I call this method, I am getting an exception as follows:

I am using Maven2, GWT 2.3 and JavaSE1.6
I know GWT can serialize ArrayList as I have used it countless times so I cant figure out what in world is going wrong over here.
Could you have forgotten to add the servlet and servlet-mapping entries in web.xml or the #RemoteServiceRelativePath annotation on your service interface?
I'd start by making sure your Async, Service, and Impl classes match up to the RPC specification exactly. GWT will throw an error if you did anything (missing parameter, different return type) differently. Take a look at the google documentation on RPC, they sufficiently describe RPC calls (in a quite lengthy fashion).
The RPC interfaces and implementation do match, otherwise you would not be able to compile. I'm quite sure what you put in the ArrayList is causing the problem. Is it a generic ArrayList or a list of certain types? Try using Java Generic (e.g. ArrayList) to help the GWT compiler optimizing your code.
