S2: NullPointerException at AnnotationActionValidatorManager.lo adFile

[Néstor Boscán]

I've been trying to make Struts 2 JavaScript Validation work on WebLogic
10.3.6. I first used 2.3.8 version and then the latest 2.3.15.2 version. I
still get the same error:

java.lang.NullPointerException
        at
com.opensymphony.xwork2.validator.AnnotationActionValidatorManager.lo
adFile(AnnotationActionValidatorManager.java:391)
        at
com.opensymphony.xwork2.validator.AnnotationActionValidatorManager.bu
ildAliasValidatorConfigs(AnnotationActionValidatorManager.java:271)

Any ideas?
