"Noinitialcontextexception" error while boosting GWT application via Eclipse

Question

I’m trying to upload an application made in GWT 2.4 in Eclipse Kepler (4.3), using Google Plugin for Eclipse.

When using the option Run As > Web Application, I immediately receive in the log the error below:

Answer 1

After researching about the error, I realized that the same occurs in this environment due to the order of loading the dependencies in classpath of the execution.

The solution was to access the menu Run > Run Configurations..., select the respective execution configuration, go to the tab Classpath and move the GWT-related entry to the top of the list.

Order of entries causing error:

Order of entries that solves the problem:
