java.lang.NoClassDefFoundError: org/json/simple/parser/ParseException

[DaniMunoz]

Copy / Pasted from App Engine Log:

Uncaught exception from servlet
java.lang.NoClassDefFoundError: org/json/simple/parser/ParseException
at com.google.cloud.backend.spi.ProspectiveSearchServlet.doPost(ProspectiveSearchServlet.java:62)

line 62 -> Sender sender = new Sender(gcmKey);

As mentioned in other issue, I have imported the missing libraries:

• gcm-server.jar
• gson-2.2.4.jar

I am using Eclipse Juno 4.2.2. with Android 4.3 (API 18). The message sent to the server is stored correctly in datastore, but this error keeps arising in the log.

Am I missing anything? Is any other library needed?
