Re: [Resteasy-users] Pool for javax.ws.rs.client.Client objects?
By default, Resteasy only allows one connection per Client. You have to
use ResteadyClient(Builder) to expand this. Other than that, it should
be threadsafe.
Personally, I'd create the Client as an application-scoped CDI bean and
inject it, or create one with SPring and inject it, or create one in a
servlet listener and add it to ServletContext. If you create per
request, then you lose any socket connection pooling that Apache Http
Client does.

could maybe declare and use a single instance like the following? (in a
JavaEE context)
@Singleton
public class SomeService {
private Client restClient;
@PostConstruct
private void init() {
restClient = ClientBuilder.newClient();
}
.
// Use restClient object here
.
@PreDestroy
private void cleanUp() {
restClient.close();
}
}

[Resteasy-users] Use Resteasy server-side Cache
Hello everyone, I develop a software which provides webservices on a tomcat. These webservices parse and display data from a 3rd website with JSOUP in XML or JSON format. Now I want to use the server-side caching to reduce the requests be made to these websites. The Project is managed with Maven and I'm using the 3.0.6.Final version of resteasy and it will all be deployed on an integrated Tomcat 7 for testing purposes. While researching on how to get the caching into my project I stumbled upon this link http://docs.jboss.org/resteasy/docs/1.1.GA/userguide/html/Cache_NoCache_CacheControl.html which I thought contained everything I needed. So I added the dependency to my pom dependency groupIdorg.jboss.resteasy/groupId artifactIdresteasy-cache-core/artifactId version3.0.9.Final/version /dependency and added the context parameter to my web.xml context-param param-nameresteasy.server.cache.maxsize/param-name param-value1000/param-value /context-param context-param param-nameresteasy.server.cache.eviction.wakeup.interval/param-name param-value5000/param-value /context-param listener listener-classorg.jboss.resteasy.plugins.cache.server.ServletServerCache/listener-class /listener But while trying to run the project on my server I get the following exception SEVERE: Error configuring application listener of class org.jboss.resteasy.plugins.cache.server.ServletServerCache java.lang.ClassNotFoundException: org.jboss.resteasy.plugins.cache.server.ServletServerCache at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1676) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1521) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:415) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:397) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:118) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4638) at org.apache.catalina.core.StandardContext$1.call(StandardContext.java:5204) at org.apache.catalina.core.StandardContext$1.call(StandardContext.java:5199) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) So I build the war with Maven - build and checked for the jar file in WEB-INF/lib/ and found the resteasy-cache-core-3.0.9.Final.jar. What is going wrong? Or is the way on approaching the server-side cache implementation wrong?
