To achieve that, you would need to store in a

问题 Can @Stateless class have different modifiers than public? In documentation I have only found constraints of constructor/methods visibility, but nothing interesting about class level access. 回答1: According to ejb3-1 specification: 4.9.2 Session Bean Class The following are the requirements for the session bean class: • The class must be defined as public, must not be final, and must not be abstract.

问题 I have a simple restful web service that uses Bean Validation 1.1 (and Hibernate Validator 5.1.3 as the implementation) and I'm deploying it on JBoss EAP 6.4.0. Since JBoss 6.4 comes bundled with Bean Validation 1.0 and its implementation library (Hibernate Validator 4.3.2), there is a conflict and none of service calls work. Below is the error that I get: java.lang.NoSuchMethodError: javax.validation.Validator.forExecutables()Ljavax/validation/executable/ExecutableValidator; org.apache.cxf

问题 I always use Jave EE 6 framework for web application. So I am not sure what I about to do is correct. I need to create an native client command-line application that has database access. So simple java Project with JDBC would do that job. But the requirements for db access include connection pool, concurrency handle, and transaction ..., Now the requirement of the projects does eventually build a web interface, but first it will build a command line application first. And this is when i am

问题 How can I control the max file size and/or the max request size when using resteasy to handle a multipart/form-data request ? My code looks like this: @POST @Path("/somerestresource") @Consumes(MediaType.MULTIPART_FORM_DATA) public Response handleForm(@MultipartForm MyForm form) { ... } With a Servlet I can control stuff with the @MultipartConfig annotation. So I'm thinking about bypassing resteasy and using @Context to inject a HttpServletRequest and having my servlet configured inside the
