Why use RESThub

[Igor Rosenberg]

Hi,

 

I’ve just started developing a REST service. I decided to go the jersey+tomcat+maven way. Then I stumbled upon RESThub. Is there information somewhere on the difference between the available REST-enabling platforms? Some comparison table between jersey, RESTeasy, RESThub & others?

 

Regards

 

Igor

Hi,

In fact we are not at the same level. RESThub is an integration
framework that give you what we consider as the best stack (Hibernate
3.5 used as JPA 2 provider, Spring 3 used with JEE6 annotations,
Jersey used as JAX-RS implementation) in order to allow you to develop
efficiently you app.

We have tried various JAX-RS implementations, especially CXF and
Jersey. And Jersey is really the perfect match for what we need. I
know that RESTeasy provide nice advanced features too, but since we
are fine with Jersey on a lot of project, we plan to keep it. When we
started, CXF did not implement JAX-RS 1.1, but I has changed since CXF
2.3 implement it.

One blocking point with CXF was that you had to configure your
webservices in a central configuration file, which is not the RESThub
way of doing that.

For your need, you could use RESThub to see how Jersey work in a full
stack example. If you have Maven and java6 installed, just type the
followjng command to create a sample project :
mvn org.apache.maven.plugins:maven-archetype-plugin:2.0:generate -
DarchetypeRepository=http://resthub.org/nexus/content/repositories/
snapshots -DarchetypeGroupId=org.resthub -DarchetypeArtifactId=resthub-
simple-webapp-archetype -DarchetypeVersion=1.0-SNAPSHOT

After that, just launch "mvn jetty:run" to have a Jersey instance
running.

You will find more information on the RESThub presentation :

Hello

 

Using the example found for resthub, I try to run:

                mvn tomcat:run

               

Compilation works fine, but when tomcat is started:

 

GRAVE: Exception starting filter JpaFilter

java.lang.ClassCastException: org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter cannot be cast to javax.servlet.Filter

        at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:275)

 

Is that a common error?

 

Thanks for any hints.

What version of Tomcat is runned with mvn tomcat:run ? Tomcat 6 ?
Could you also check that it works with jetty:run instead ?

Hi,

Works flawlessly with 'mvn jetty:run'. I don't think Tomcat is the one I've installed myself - I didn't change the pom.xml, I don't think maven could infer I had a local tomcat (which is not running). I think it's instead the one maven downloads (Apache Tomcat/6.0.29), as it states:
Searching repository for plugin with prefix: 'tomcat'.

The trace has more info:

[INFO] [tomcat:run {execution: default-cli}]
[INFO] Running war on http://localhost:8080/RESTapp
[INFO] Using existing Tomcat server configuration at D:\resthub\RESTapp\target\tomcat
26-nov-2010 15:10:43 org.apache.catalina.startup.Embedded start
INFO: Starting tomcat server
26-nov-2010 15:10:44 org.apache.catalina.core.StandardEngine start
INFO: Starting Servlet Engine: Apache Tomcat/6.0.29

Thanks for helping
Igor

On our side we usually run RESThub applications in jetty:run while
developping, and on Tomcat on production, and we have no issues.
Perhaps you could deploy your war in a vanilla Tomcat to check the
result. I would suspect an issue in Tomcat Maven integration, which is
far away from jetty one.
