hk2 | A light-weight and dynamic dependency injection framework | Dependency Injection library

For simplifying our web services I'd like to introduce a custom MyObj class using the Jersey framework in version 2.34 and want to inject the created instances via the @Context annotation.

I have two questions:

1. Assuming a web service method @GET test(@Context MyObj obj), how can I control when instances of MyObj are created in respect to the execution of existing servlet request filters?

2. To create instances of MyObj, I already have a working example based on HK2's Factory's (see below). Since I observed that my factory class gets instantiated twice, and Jersey 2.26+ recomments to use the newer approach based on Supplier's, I tried to convert my example. Unfortunately, configure() won't be called in the provided Binder implements Supplier class, and thus, no objects get created. How can I get this working? (Btw., In both cases, Binder and BinderHK are registered via jersey.config.server.provider.classnames in my web.xml.)

Thank you for any help.

Working HK2 Factory example:

I have that error when i execute my getCustomers() method in Postman. The problem is that for some reason executes the method getOrder() isntead of just getCustomers(), if i let it uncommented. I have searched about this issue but i was not able to find anything that worked in my case. Any help will be very apreciate.

Error:

I have actually a similar problem as described here JAX-RS Resource not found in GlassFish Server. Since one should not ask for help in the answers I make a new question.

I created a project named "SPCore" which is a simple RESTful Webservice. It uses jax-rs libs, jdk 11 and a Tomcat 9.0.44 server. I have an index.html in the webapps folder which shows Hello World. The context path is set to /sp-core. If I'm calling localhost:8080/sp-core the index.html file is returned. So that works.

I have some resources (I will only show one as example). The resource "ProcessEventResource" should return "hello world" as plain text when a GET request comes. The path is set to @Path("processEvent"). Sadly I get an error 404 when I'm calling localhost:8080/sp-core/processEvent

I tried so far:

1. add an / at the beginning of the path declaration

2. I added a subclass application as mentioned here in the updated answer JAX-RS Resource not found in GlassFish Server. Still I get the 404 error when calling localhost:8080/sp-core/api/rest/processEvent

I have the assumption that something with the servlets or paths is not working correctly.

In the following I will provide my project structure, the pom file, the resource and the application class. I cut some small parts (package names, group-id, ...) which refers to the company I'm working for. If you need more Information please let me know.

Project structure

pom.xml:

I have a small JAX-RS (Jersey 3.0.1) API running in a standalone Jetty 11 but want to use Weld 4.0.0 instead of HK2. The Jetty bootstraps the Weld context properly (Jetty module ci-decorate was installed as described in the Weld documentation)

In my test application I have my security configuration class as follows.

I am trying to stream from a Kafka topic to Google BigQuery. My connect-standalone.properties file is as follows:

Local tomcat is not starting and it is failing when trying to creating bean that connects to Oracle DB. The error is java.sql.SQLRecoverableException: IO Error: Connection reset. The only change we made is, we used ojdbc8.jar dependency in Pom.xml earlier it has ojdbc6.jar. I am running the tomcat on jdk 1.8 library/java/javavirtualmachines/jdk1.8.0_162.jdk/Contents/home/jre/

We have imported the rds-ca-2019-root.der in to the cacerts file. library/java/javavirtualmachines/jdk1.8.0_162.jdk/Contents/home/jre/lib/security/cacerts

This is happening after updating the SSL_VERSION to 1.2 on Oracle 12.2.0.1 RDS server.

Here is the stacktrace.

I want to run a Dropwizard (a REST Application).

I have a pom.xml file that uses old version of dropwizard (1.0.3) and it works. And there is another pom.xml available bellow for the new version (2.0.10) but it does not run.

Here is the working pom.xml (1.0.3 version of DropWizard) which is available on githut :

Just copy past the pom.xml to reproduce the error or the working version.

Here are the two pom.xml files :

• Here is the corresponding pom.xml for old DropWizard Release (1.03 ) that works

I'm writing an E2E Test for my REST-Application. So the test, that is located in the frontend, calls the deployed backend, this is working perfectly fine except for one tiny problem: When the readEntity Method on the received Response is called, an java.lang.ArrayStoreException occurs. My observations show that the Problem lies within a self written Constraint Annotation:

I've written my own Constraint-Annotation @Future for Bean-Validation, my POJO uses this Annotation to validate that a LocalDateTime is in the future. I've also provided two simple Interfaces, which are used as Validation-Groups:
