Migrating existing Rest Easy Project to SpringBoot
by Lloyd Fernandes
Team,
I am trying to integrate my existing project from RestEasy implementation to SpringBoot 2.x
My current project settings has two application classes(javax.ws.rs.core.Application): App1 and App2
Three Provider Classes: P1, P2 and P3
The providers are registered to the applications as follows:
App1 --> P1, P2
App2 --> P1, P3
Applications are registered by updating the singletons set in the Application Constructors of App1 and App2. Example:
public App1{ singletons.add(new P1()); singletons.add(new P2());}
I was referencing the RestEasy - SpringBootStarter :https://github.com/resteasy/resteasy-spring-boot/blob/main/mds/USAGE.md. Had the following questions after reading the description:
1. I do not see the use of such singletons recommended anymore. So how do I ensure, that the Providers are registered to the correct Application?
2. How do i convert the context param, filter-mapping, login-config, security constraint configurations defined in web.xml to the equivalent SpringBoot configurations that would work with Rest Easy.
3. What has more precedence the SpringBoot Security modules or the RestEasy security constraints?

RESTEASY003210: Could not find resource for full path
by Edoardo Panfili
Hi,
I am switching from (tomcat8+java8+resteasy3.6) to (tomcat9+java11+resteasy4)
All seem works fine except the home page of my application.
If I point the browser to "http://localhost:8080/myApp/" this is the answer:
"RESTEASY003210: Could not find resource for full path: http://localhost:8080/myApp/"
Don't know why resteasy is responding outside the application path, can someone help me?
this is my configuration:
---------------------------------
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/ws")
public class WebServices extends Application {
}
---------------------------------
In my pom.xml file I am using this dependencies:
org.jboss.resteasy:resteasy-jaxrs-all:4.0.0.Final
org.jboss.resteasy:resteasy-jackson2-provider:4.0.0.Final
org.jboss.resteasy:resteasy-servlet-initializer:4.0.0.Final
thank you
Edoardo

jakarta.ws.rs vs javax.ws.rs
by Benno Fünfstück
Hello,
I see that resteasy uses the `javax.ws.rs` package. But the jakarta EE
jars provide `jakarta.ws.rs`. It seems that the two namespaces are not
compatible. What's the relation between them?
Best,
Benno

Microprofile config
by Alvaro Arenas
Hi,
I am adding my project to a stream down wildfly v23 (withou microservices modules) and I use smallrye-config in my project. When adding my deployment with the microprofile configuration package incleded (for example "org.apache.geronimo.config:geronimo-config-impl:1.2.2") the souces in the file org.eclipse.microprofile.config.spi.ConfigSource get automatically added by wildfly but the implementation class is not found.
I get the following error
Caused by: java.lang.NoClassDefFoundError: Failed to link org/jboss/resteasy/microprofile/config/ServletConfigSource (Module "org.jboss.resteasy.resteasy-jaxrs" version 3.15.1.Final from local module loader @fc1522fa (finder: local module finder @4332406a (roots: /Users/alvarena/hki/keycloak/standalone/keycloak-13.0.0/modules,/Users/alvarena/hki/keycloak/standalone/keycloak-13.0.0/modules/system/layers/keycloak,/Users/alvarena/hki/keycloak/standalone/keycloak-13.0.0/modules/system/layers/base))): org.eclipse.microprofile.config.spi.ConfigSource

... 26 more
I don't understand how the system is able to find the file org.eclipse.microprofile.config.spi.ConfigSource but not the implementation classes that are in the same package.
Any idea what could be wrong
Best regards,
Alvaro

resteasy XXE vulnerability
by Wang Veronica
Hi experts,
We use resteasy 3.0.6final, and XXE vulnerability was reported during penetration test.
Seems that 3.0.6final contains partial fix for XXE vulnerability, but need to set resteasy.document.expand.entity.references parameter to false explicitly. A more complete fix seems to have been done after 3.0.10.
We can upgrade to a more recent version, e.g. 3.1.2. Another option I am thinking is not to support XML Media type (we actually need to support json only). Is this a feasible approach to ultimately avoid XXE attack and any pointers to achieve this? (In our REST API code, we currently declare consume and produce annotations to support application/xml and application/json).
Is there a simple resteasy configuration to disable support of application/xml?
Thanks, Veronica

Resteasy multipart filename
by Gunnar Schmid
Hello,
I'm using Resteasy client to upload files to a service.
I can set the filename using the @PartFilename annotation:
@FormParam("file")
@PartType(MediaType.APPLICATION_OCTET_STREAM)
@PartFilename("staticfilename.bin")
public InputStream file;
But this sets the filename at compile time - how can I make this dynamic?

Integration with Spring Boot v1 and Prometheus
by Alexandre Briani Kieling
Hi,
What's the best way to instrument a REST API based on Spring Boot v1 and
RESTEasy?
I noticed that Micrometer doesn't integrate with RESTEasy, only Spring MVC
and Jersey.
Should I use the Prometheus Java client?

Adding the list back as I dropped it by mistake.

There is no way that I'm aware of to associate a converter with a type.
However, returning null is the way to stop processing a
ParamConverterProvider.
