Resource not invoked after Jersery Request Filter
spring,jersey,jax-rs,jax-ws,servlet-filters
I have solved the problem, but I am not 100% sure if my solution is the correct way to do it. I have changed the annotation on the filtered serlvet to be @WebFilter, giving me @WebServlet(urlPatterns = { "/*" }, initParams = { @WebInitParam(name = "com.sun.jersey.config.property.packages", value = "com.x.y.resource"), @WebInitParam(name...

Why does QueryParam return null
The problem is you are trying to write to the body of the request, with wr.write("enc="+encData);. @QueryParams should be in the query string. So this instead would work public static void main(String[] args) throws Exception { sendPost(".../encRead", "HelloWorld"); } protected static void sendPost(String url, String encData) throws Exception { String...
Getting Unsupported Media Type when trying to access POST Json consumer endpoint developed using Jersey

The only problem I faced was this exception ...IllegalAnnotationsException... Activite does not have a no-arg default constructor. To fix it I simply added a no-arg constructor in the Activite class.

How to set username and password using Rest easy client builder?
java,http,http-headers,jax-rs,resteasy
Looks like Basic Authentication. If that's the case, you just need to set the Authorization header to Basic base64encode(username:password) For example String credentials = "username:password" String base64encoded = Base64.getEncoder().encodeToString(credentials.getBytes()); Response response = target.request() .header(HttHeaders.AUTHORIZATION, "Basic " + base64Encoded).... The Base64 class I used is from Java 8. If you're not...
How to configure Jersey (javax.ws.rs.*) to reuse ssl sessions

EJB injection not working in different classes
java-ee,netbeans,jersey,ejb,jax-rs
You're creating an ActivityManager yourself, using new ActivityManager(). So the basic rules of Java apply: the constructor is called, and since it doesn't affect any value to activityfacade, this field is set to null. For dependency injection to happen, you can't create the objects yourself, but get them from the...
Jersey Client/JAX-RS and optional (not default) @QueryParam

JAX-RS Custom JSON representation of primitive Resource return type
Not sure if it's a good idea. Would be much better if you'll create new JAX-RS resource and designated entity-class to response with. Still, if you want to mix marshalling with model, you could write your own MessageBodyWriter. For example: @Produces("application/json") public class IntWriter implements MessageBodyWriter<Integer> { @Override public boolean...

JAX-WS @WebService on RESTful web-service endpoint
Exposing a JAX-RS bean as the methods of a SOAP WS using @WebService may be technically possible. It will not lead to a good API design.

How to write single JAX-RS resource for variable number of path parameters
You can use a regex, like @Path("/college/{param: .*}"), then use List<PathSegment> as a method parameter.

In fact, if you look at the content type of the data you send within your request, this corresponds to a multipart content and not a URL-encoded form. The code you use within your server resource only applies to URL-encoded form (content-type application/x-www-form-urlencoded). So it's normal that you can get...

How to implement JAX-RS RESTful service in JSF framework

Exception in the allocation for the servlet
java,angularjs,rest,jersey,jax-rs
There are so many things wrong on so many levels There is no such word as "Authentification". It's "Authentication" :-) @ApplicationPath should be used on the application configuration class, not on your resource classes. For example @ApplicationPath("/rest") public class AppConfig extends PackagesConfig { public AppConfig() { super("the.packages.to.scan.for.resources.and.provders"); } } With...

Preventing infinite recursion in JAX-RS on JPA Entity Serialization (JSON) (without using Jackson annotations)
java,jpa,jackson,jax-rs,resteasy
Yes. Create a dedicated data structure, the representation data structure and map the JPA entity to the data structure. You're mixing concerns and this usually ends up badly. JPA entities are your API towards your data structure, REST representations are your API towards REST.
Reading from a JDBC Blob after leaving the Spring transaction
jax-rs,blob,spring-transactions
I've spent some time now debugging the code, and all my assumptions in the question are more or less correct. The @Transactional annotation works as expected, the transaction (both the Spring and the DB transactions) are commited immediately after returning from the download method, the physical DB connection is returned...

How to disable common name check in SSLContext in java?
java,ssl,jersey,jax-rs,ssl-certificate
If I'm understanding you correctly, I think you can accomplish what you are trying to do by implementing a HostnameVerifier, and just returning true in the verify method. You can set up the verifier on the ClientBuilder. For example Client client = ClientBuilder.newBuilder() .sslContext(sslContext) .hostnameVerifier(hostnameVerifier) .build(); ...
