@WebServices look up EJB's on every single http request (not only webservice
requests)
--------------------------------------------------------------------------------------
Key: SEAMFACES-55
URL: https://jira.jboss.org/browse/SEAMFACES-55
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration
Affects Versions: 3.0.0.Alpha3
Environment: Glassfish 3.0.1 on Windows 7 64 bit, 32 bit jvm (1.6.0_20)
Reporter: Anders Ã…berg
After splitting our application into frontend (JSF2) and backend (EJB3.1
remote) modules running on different servers, performance in the application
became horrible. Rendering an empty JSF page took about 3 seconds.
It turned out that because of 3 @WebService annotated beans with remote @EJB's
injected, lots of traffic goes to the backend server on every http request (to
JSF pages, css, js etc). We don't know exactly what this traffic is, but adding
breakpoints in @PostConstruct methods in the webservices showed that they are
not being instantiated.
After removing seam-faces the problems went away. And if we annotate the
webservices with @Stateless they also went away. So we have a workaround, but
would like to know if this issue could affect other areas as well. Performance
is still sub par.
More info here:
http://seamframework.org/Community/SeamFaces300Alpha3WeirdButSeriousPerformanceIssue
I have created some webapps to reproduce the problems:
faces-server: webapp with a remote ejb EchoService
faces-client: webapp with an empty jsf page (meaning just plain text) and an
EchoWebService that injects EchoService using @EJB
faces-client-seamfaces: identical to the one above but with
seam-faces-3.0.0.Alpha3 in WEB-INF/lib. And different name obviously.
Steps to reproduce problem (on Glassfish 3.0.1 at least):
- Deploy faces-server first, and then both faces-client and
faces-client-seamfaces.
- Open /faces-client/empty.xhtml and /faces-client-seamfaces/empty.xhtml.
Rendering the first one takes about 4-6ms, the second one takes 60-80ms.
- Undeploy faces-server and try to reload the pages. The first one still works,
the second one gives an exception:
