• why jsessionid is appended to each url?

  - by sword101

  greetings all i am deploying an app using spring framework on the apache tomcat when running the application from the tomcat directly,there's no jsessionid appended to any url at all but after mapping the application to the domain,and trying to run it i got a jsessionid appended to each url in the application,i tried the spring security attribute disable-url-rewriting but it doesn't work,it removes the jsessionid from the url but the application doesn't work no more,the user cannot login. so i guess it's another problem,any ideas why this happens,how to solve it? thanks.

• What's the most minimal way to achieve Dependency Injection?

  - by Chuck

  I've been reading about Spring and although it's claimed to be a less complex alternative to EJB, I'm having a hard time wrapping my head around it. Is there a more minimal way of achieving Dependency Injection than adopting the Spring approach?

• Finding out if LDAP user in Sun Directory Server 5.2 is locked out, in Java

  - by simon

  I'm developing an application using Java, Tomcat, Spring Framework and Spring LDAP 1.2.1 for LDAP access. According to our LDAP administrator, it is not possible to find out programmatically, if a specific user is locked out in the directory - the user is just not returned. This makes life difficult for me, as I need to identify locked out users. Is our administrator right, or is it possible somehow to find out, if a particular user is locked out? If yes, how?

• JSF data transfer between UI and business layer

  - by Ram

  Hi, We are using JSF in UI, Spring in business layer, Hibernate in persistence layer. Now my question is how to pass data from the JSF UI to spring business layer. Can I directly use my business object in my backing bean or should I transfer data between the layer through DTO? Can one explain me with clear explanation if possible with piece of code and that related websites?

• How to catch an exception and email information about it in liferay portlet

  - by heikkim

  I have a custom portlet made for liferay and sometimes it throws an exception. Why it throws exceptions is irrelevant. How to catch exceptions thrown by portlet handler methods in order to email information about them? I know I could do try catching on every handler method but it would be a much more elegant and cleaner solution to catch the exception on a higher level and just email some information about the error. I'm using Spring Portlet MVC, so i got all spring-related niceties at hand.

• What web platform is right for me?

  - by egervari

  I've been looking at web frameworks like Rails, Grails, etc. I'm used to doing applications in Spring Framework with Hibernate... and I want something more productive. One of the things I realized is that while some of the things in Grails is sexy, there are some serious problems with it. Grails' controllers: 1) are implemented awfully. They don't seem to be able to extend from super classes at runtime. I tried this to add base actions and helper methods, and this seems to cause grails to blow up. 2) are based on an obsolete request parameters model (rather than form backing objects, which are much nicer). 3) are hard to test. Command objects are treated totally differently... and it's actually MUCH harder to write the test than it is to write the controller code. 4) Command objects operate totally differently. They are pre-validated and bound, which causes a lot of inconsistencies than basic parameter model. 5) Command objects are not reusable, and it's a pain in the rear to reuse most of the stuff from the domain classes, like constraints and fields. This is TRIVIAL to do in basic Spring. Why the hell was it not trivial to do in Grails? 6) The scaffolding that is generated is pure crap. It doesn't generalize inserts and updates... and it actually copy/pastes a pile of code in two views: create.gsp and edit.gsp. The views themselves are gargantuan piles of doggie do-do. This is further compounded by the fact that it uses low-level parameters and not objects. Integration tests are 30x slower than a Spring integration test. It is disgusting. Some mocking tests are so hard to write and aren't guaranteed to work when it's deployed, that I think it discourages fast, tdd test cycles. Most things seem to screw up grails while it's running, like adding a taglib, or anything really. The server restart problem wasn't solved at all. I'm starting to think going with Spring/Hibernate/Java is the only way to go. While there is a pretty big cost at startup, I know it'll eventually smooth out. It sucks I can't use a language like Scala... because idiomatically, it is so incompatible with Hibernate. This app is also not a run-of-the-mill UI over a database. It's got some of that, but it's not going to be a slouch. I am deathly scared of Grails now because of how crap it is in the Controller layer. Suggestions on what I can do?

• How does init() get called on a Handler in a WebApp

  - by stevebot

  Hey, I have a Handler object that functions kind of like a service. It has a public init method defined in the Implementation but not the Interface. This Handler is also being autowired via Spring. How does the init method get invoked? Is it via Spring or does Tomcat call this?

• Passing Request Object into Service Layer

  - by SpringTrickery

  In a spring mvc + spring core app, we have have a view layers, a facade, a service layer, a dao layer and a stored-proc based persistance layer. The service layer is unaware of the clients that utilitize its methods. Is it fine to propagate raw http requests into the service layer? Or is it bad practice and a violation of the loose coupling principles? If it is, then what's a clean workaround?

• A file is being http posted, how can I reference the parameter by index?

  - by Blankman

  An XML file is being posted to a url that my spring mvc is responding to. In .NET, I could do this: request.Form[0] request.Form["abc"] or request.QueryString[0] request.QueryString["some_key"] Now with spring/servlets it seems I can only do this: request.getParameter("some_key") or get all the names or values. When someone is posting a file to a url, using http post, won't this be just a single request parameter then? Can I get the parameter using index with servlets?

• Can @Inject be made option in JSR 330 (like @Autowire(required=false)?

  - by Eric B.

  Spring's @Autowire can be configured such that Spring will throw an error if no matching autowire candidates are found: @Autowire(required=false) Is there an equivalent JSR-330 annotation? @Inject always fails if there is no matching candidate. Is there any way I can use @Inject but not have the framework fail if no matching types are found? I haven't been able to find any documentation to that extent.

• setProperty must be overridden by all subclasses of SOAPMessage

  - by Pablo

  I'm trying to deploy some web services in a WAR application on JBoss 5.1.0. I have created the source files from an existing wsdl using JAX-WS tool wsgen. This created the Service files and @XmlType annotated clases that would act as request and response wrappers. This classes worked well on JBoss 4.2.3, but when moving to JBoss 5.1.0, I get this exception. java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage My configuration: Windows XP SP3 (but getting the same on Vista, as well as on Linux) Sun JDK 1.6.0_17 JBoss 5.1.0 GA for jdk6 Thanks in advance!

• Retrieving WSDL file from secure service

  - by Anonimo

  I have a Web Service developed with JAX-WS. I have secured the web service with BASIC authentication configured in Tomcat. When I try to access the web service using a Java client, I first need to create the port, and then specify the credentials, as follows: CustomerServiceClient customerServiceClient = new CustomerServiceBottomUpService(); //1 CustomerService customer = customerServiceClient.getCustomerServicePort(); //2 Map<String, Object> context = ((BindingProvider) customer).getRequestContext(); //3 context.put(BindingProvider.USERNAME_PROPERTY, "kermit"); //4 context.put(BindingProvider.PASSWORD_PROPERTY, "thefrog"); //5 The problem I have is that, after line 1, I get an Authorization error (HTTP 401) as I obviously haven't provided the server with the credentials yet. I am creating the client artifacts from a server WSDL, hence the authentication problem when creating the service, and don't want my clients to store the WSDL locally as it's just annoying for them. How can I get around this problem?

• How to generate proxy for a child class when my web service return a parent class?

  - by Amir Borzoei

  Hi * I have a web method like this: public class ParentClass{ public String str1; } public class ChildClass : ParentClass{ public String str2; } public class WebService{ public ParentClass WebMethod(){ return GetFirstChildClass(); //Return a child class } } When I generate proxy for this web service by Visual Studio, VS just generate proxy for ParentClass but I need ChildClass too. For workaround I add a dummy method to WebService that return ChildClass to generate proxy for ChildClass in client. public class WebService{ ... //This is a dummy method to generate proxy for ChildClass in client. public ChildClass DummyWebMethod(){ return null; } } In addition I write web service in java (JAX-WS) and my client is a SilverLight Application. Is there a better solution for this problem? tanx for your help ;)

• Creating a web-service client directly from the source

  - by ben

  Hi, I am trying to generate the WS client jar directly from the @Webservice class(es). Let's take this example : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } I can generate a war file and use glassfish to serve this webservice, and from there I can use the glassfish WSDL URL to generate the client sources. What I am trying to do is to skip the glassfish part. From my maven project defining the webservice, I would like to use the jaxws-maven-plugin to create the client classes but I cannot find any way to specify the actual URL of the webservice. It should be possible right? @see also http://stackoverflow.com/questions/2097789/creating-a-web-service-client-with-a-known-but-inaccessible-wsdl

• Invoke webservice using jaxws when the wsdl has more than one service

  - by Hugo Palma

  I'm trying to get hold of the FindService on this wsdl using jaxws. I generated the classes just fine using wsimport. But when i do: FindService findService = new FindService(); i get the exception: Exception in thread "main" javax.xml.ws.WebServiceException: {http://s.mappoint.net/mappoint-30/}FindService is not a valid service. Valid services are: {http://s.mappoint.net/mappoint-30/}CommonService So, it seems that jaxws is only finding CommonService in the wsdl which is the first one declared in it. Any idea how i can use the FindService ? Thanks.

• Java: using endpoint to publish webservice to tomcat server

  - by Will

  hi all, i am creating a simple SOAP web service. i am to ensure that it runs on a tomcat web service. im trying to implement this with JAX-WS (see code) my question is: does the Endpoint.publish use the tomcat server to host this or is it a mini glassfish kind of server? should i be extending UnicastRemoveObject or something similiar instead? ideally it would be able to be packaged into a .WAR and dropped in the directory and just work. It doesn't seem to work with my installed tomcat server as is because it says the port is already in use. I'm using Ubuntu karmic with the tomcat6 package installed, it could also be my user doesnt have permissions to publish to the running tomcat on 8080 i hope this question is clear enough sample code: @WebService public class UserAttributes { public static void main(String[] args) { UserAttributes instance = new UserAttributes(); Endpoint.publish("http://localhost:8082/WebServices/userattributes", instance); } public string Hello() { return "Hello World"; } }

• Exceptions and web services

  - by Schildmeijer

  Im using the standard java ws implementation shipped with e.g. java6 (javax.jws.*). I have the following: import javax.jws.*; @WebService(name="Widget") public interface Widget { @WebMethod public @WebResult String getGadget(@WebParam(name = "id") long id) throw MyOwnException; } Is this possible? Do I have to annotate MyOwnException with e.g the @WebFault annotation? During my initial tests I also noticed that, on the client side, the autogenerated MyOwnException was renamed to MyOwnException_Exception and wrapped the "original" MyOwnException. Or if this is a bad idea, are there any recommended Exceptions to throw from a webservice like this?

• Getting Raw XML From SOAPMessage in Java

  - by Daniel Lew

  I've set up a SOAP WebServiceProvider in JAX-WS, but I'm having trouble figuring out how to get the raw XML from a SOAPMessage (or any Node) object. Here's a sample of the code I've got right now, and where I'm trying to grab the XML: @WebServiceProvider(wsdlLocation="SoapService.wsdl") @ServiceMode(value=Service.Mode.MESSAGE) public class SoapProvider implements Provider<SOAPMessage> { public SOAPMessage invoke(SOAPMessage msg) { // How do I get the raw XML here? } } Is there a simple way to get the XML of the original request? If there's a way to get the raw XML by setting up a different type of Provider (such as Source), I'd be willing to do that, too.

• How to write web services in java

  - by gurupriyan.e

  Though this might appear as a duplicate of Java Web Services , I would like to know Where to start and to continue.In the past, I have invested so much of time to find where to start but I wasn't able to. There are so many jargons and chaos (at least for me!) while reading the pages about web services. There are so many terms - like JAX-RPC, JAX-WS, Axis, Rest, Servlet as WebService, EJB's as Web Service and other terms that I don't know. Can this User group consolidate and give a highlevel overview of Java Web Services which is easy to understand and follow? I appreciate your kindness and thanks for your help.

• Web Service Security java

  - by WhoAmI

  My web service was created some time back using IBM JAX-RPC. As a part of enhancement, I need to provide some security to the existing service. One way is to provide a handler, all the request and response will pass through that handler only. In the request I can implement some authentication rules for each and every application/user accessing it. Other than this, What are the possible ways for securing it? I have heard someting called wsse security for web service. Is it possible to implement it for the JAX-RPC? Or it can be implemented only for JAX-WS? Need some helpful inputs on the wsse security so that i can jump learning it. Other than handler and wsse security, any other possible way to make a service secure? Please help.

• Eclipse plugins for Spring / Hibernate development?

  - by es11

  I have a running dynamic web project in Eclipse (Java EE + Maven + Spring). I am at the point where I need to integrate a persistence layer and want to use Hibernate with a mySql database. I am wonder what plugins would be useful for me at this point? For Hibernate should I install hibernate tools or is it not necessary? Are then any plugins that are most widely use for connecting / exploring database connections that would be appropriate for the type of project I am working on? Thanks.
