Re: gwt compilation issues while upgrading from GWT 2.7.0 to GWT 2.9.0

Hi All,

Thanks to your support, I was able to resolve the compilation issue just by changing to GWT 2.9.0 and removing gwtx.

There were changes which i had to do because of removal of gwtx. Like not using java.text classes (SimpleDateFormat, DecimalFormat etc.) and using GWT compatible classes as an alternate.

I also faced issues due to removal of closure compiler. Had to do some refactoring to remove unused classes from the mentioned <source path= package

Thanks again to all.

IIRC, gwtx replaces/shadows some emulated classes; it's likely that it's the one causing issues here.

Try compiling with -failOnError, and/or look at the beginning of the compiler output for early problems that will cascade and cause everything else to fail.

Hi Team,

Currently we are using SmartGWT 4.1 LGPL, GWT 2.7.0 & Java 1.8 with below supporting libraries

gin-2.1.2.jar

gwtexporter-2.4.0.jar

guice-3.0.jar

javax.inject.jar

guice-assistedinject-3.0.jar

aopalliance.jar

gwtx-1.5.2.jar

While just upgrading to GWT 2.9.0 and doing gwt compile, i am getting below error,

[ERROR] Unable to find class java/lang/Enum

     [java]          Resolving method valueOf

     [java]             [ERROR] Unable to resolve type java/lang/String of argument arg0

It is also having too many occurrences of below error,

[ERROR] Unable to find class java/lang/Object

Any suggestion about how to resolve it, or if you need more details ?

Thanks
