public ModelAndView Details(@ModelAttribute("") @Validated App app, BindingResult result, @RequestParam(value="paramSessionAttr", required=false) String sessionAttr, @RequestParam("paramAction") @NotNull @NotEmpty String param_action){ ... }
When I implement @NotNull
@NotEmpty
annotation validator in getParam its cause error said :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'appController' defined in file [C:\apache-tomcat-8.0.29\wtpwebapps\Application Portal\WEB-INF\classes\com\controller\AppController.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.controller.AppController]: Constructor threw exception; nested exception is java.lang.Error: Unresolved compilation problems:
The type javax.validation.Payload cannot be resolved. It is indirectly referenced from required .class files
The import javax.validation cannot be resolved
Using hibernate-validator-5.2.2.jar
Tomcat 8.0
spring-4.2.3.jar
When I Import javax.validator which is validation-api-1.1.0.jar [JSR-349]
its cause this error,
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl
When I remove @NotNull
@NotEmpty
and validation-api-1.1.0.final
working fine.
When I import validation-api-1.1.0.final
without @NotNull
@NotEmpty
I got this error
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl
I tried download from other source and import validation-api-1.1.0.final
I also got the same error as above.
I have found org.hibernate.validator.internal.engine.ConfigurationImpl
in hibernate-validator-5.2.2-Final.jar
servlet Possible bean configuration missing something ?

Imported Library
REFERENCES
I guess some library is missing because I download library à la carte
you download from here as a package instead of you download à la carte
setup GUIDELINE http://hibernate.org/validator/documentation/getting-started/
Import and include library below in your project
Then your code should be working.
