问题 I'm using GWT for a class project, and although everything worked before, I recently refactored my code and suddenly I'm running into the title error. I searched around and it seems that the GWTBridge problem is caused by 2 main things: a) a bug which was fixed for 2.5.1, or b) trying to call client-side code from the server and vice versa (classNotFoundException GWTBridge). I'm using GWT 2.5.1 and I'm 99% sure I'm not violating case b), so I'm at a loss. I literally just copy and pasted code

问题 This question already has answers here : Do I know if I need Multi-Dex enabled? (ClassNotFoundException) (2 answers) Closed last year .

问题 I inherited a JBOSS 4.2.3.GA . ear project in which everything loads and runs fine if I build it with JDK 7u45, but fails to load & run early in the JBoss Bootstrap if I build it with any newer update of JDK 7 (e.g. 7u76, 7u79, 7u80). The JBOSS server itself runs on Java 1.7.0_45. The logged reason for the failure is a ClassNofFoundException for a class that is actually there (even for the failing .ear): log4j:ERROR Could not create the Layout. Reported error follows. java.lang
