问题 In java EE, the way you get an EJB from a remote server is by looking it up in JNDI. The specification defines the JNDI name for a given bean type. However, this seems to be only if you want to get a bean off your local computer. I want to get the bean off a remote server, like most users would. How do I specify the server URL? Do I pass a map to the InitialContext constructor? Note: There is another question that is pretty much the same, but that has become out of date since the definition

问题 I am fairly comfortable with standalone Java app development, but will soon be working on a project using a Java EE application server. Does anyone know of a straightforward how-to tutorial to getting a hello-world type application working in an application server? I'm (perhaps naievly) assuming that the overall approach is similar between different frameworks, so I'm more interested in finding out the approach rather than getting bogged down in differences between the different frameworks.

问题 Am trying to gain control over the URL endpoints of my web services when deployed to Glassfish (and preferably to TomEE too). I have a class: @Stateless @WebService( targetNamespace = "http://foo.net/doc/2012-08-01", name = "FooService", portName = "FooPort", serviceName = "FooService") public class FooSoapService extends SoapBase { ... } And a web.xml: <servlet> <description>SOAP Endpoint for Foo operations.</description> <servlet-name>Foo</servlet-name> <servlet-class>com.foo.FooSoapService

问题 I wrote a simple web service program but I can not test it on glassfish 4.0 web server . When I Test Web service I see this message : Make sure the service has been deployed successfully, and the server is running. I can see it in list of deployed web services on glassfish web server . and I add this file to \jdk1.8.0\jre\lib to fix the problem. jaxp.properties javax.xml.accessExternalSchema = All But it doesn't work Also I see this error in url of tester page : lineNumber: 52; columnNumber:

问题 I've set up a simple jersey server like this: ResourceConfig rc = new ResourceConfig().packages("com.example.jersey_test/services"); HttpServer server = GrizzlyHttpServerFactory.createHttpServer(URI.create(API_URI), rc); And I have a bean that simply throws an exception: @Path("persons") public class PersonService { @GET @Produces(MediaType.APPLICATION_JSON) public String getPersons() { java.util.logging.Logger.getGlobal().log(Level.INFO, "test"); throw new RuntimeException("test"); } } The

问题 I have recently started developing another GWT module. So I created a package with all my new classes and one specific class that implements a new entrypoint. I modified in my gwt.xml to my new entrypoint. When I compile, I get the following error: GWT Compiling client-side code. WARNING: 'com.google.gwt.dev.GWTCompiler' is deprecated and will be removed in a future release. Use 'com.google.gwt.dev.Compiler' instead. (To disable this warning, pass -Dgwt.nowarn.legacy.tools as a JVM arg.)

问题 I have three tables in my database, a Student, a Classe, and an Assignement. The POJOs are as the following: Student{ Classe currentClasse; Set<Assignement> assignements; } Classe{ Set<Assignement> assignements; SchoolYear schoolYear; } Assignement{ Classe classe; Student student; Boolean pass; } Basically, a student has a current class, and a list of assignements (all the classes he's been assigned to). My problem is that under hibernate, I'd like to know all the students who do not have a

问题 I have a server dedicated for static contents so I don't want to use the resources dir for storing javascript files but I don't want to stop using the <h:outputScript /> tag. How can I make that tag generate a link to my static server where the files are located instead of RES_NOT_FOUND . I don't even need JSF to check if the files are there... I tried: <h:outputScript name="#{requestBean.staticURL}/javascript.js"/> To generate: <script type="text/javascript" src="http://static.server.com
