[Resin-interest] resin:set and resin-web.xml
I define an EL variable using resin:set in resin.conf (under the host element). Then this EL variable is referenced from the resin-web.xml file of a webapp. This used to work in 4.0.10 and 4.0.15, but it does not work in 4.0.18. For example a resin:message after resin:set displays the variable correctly, but the same resin:message in in resin-web.xml displays an empty value . Should this still work or something has changed in the meantime? By the way the documentation at http://www.caucho.com/resin-4.0/admin/config-el-ref.xtp#resinset refers to both var and name attributes. Out of these two, only var works. ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest

Re: [Resin-interest] How to make this simplest CanDI work ?
BTW , Is META-INF/beans.xml defined in the JavaEE spec ? What's the
relation with beans.xml and resin-web.xml ?
yes, beans.xml is part of JSR-299.
resin-web.xml has the same role as web.xml, it is processed by Resin
after web.xml. You can place resin specific / non-standard configuration
into resin-web.xml.

I am new to CanDI , I want to migrate my spring app to JavaEE6 , but
having a lot of troubles in Resin (4.0.5) CanDI :
There is no working sample in the resin site , most are outdated ...
Here is my very basic sample , just JPA 2 and a Servlet :
public interface PersonDao {
public Person get(long id);
}
public class PersonDaoImpl implements PersonDao , Serializable {
@PersistenceContext(unitName = mining, type =
PersistenceContextType.EXTENDED)
EntityManager em;
@Override
public Person get(long id) {
return em.find(Person.class , id);
}
}
public class HelloServlet extends HttpServlet {
@javax.inject.Inject
private PersonDao personDao;
@Override
protected void doGet(HttpServletRequest hreq, HttpServletResponse
hres) throws ServletException, IOException {
PrintWriter out = hres.getWriter();
System.out.println(personDao = + personDao); // outputs Null
Person p = personDao.get(1L); //NPE , personDao is not injected
out.println(Hello, world! , person = + p);
out.close();
}

This is a very basic Dao + JPA pattern , but I cannot find how to

Can somebody give me a hint ? Thanks in advenced !

Re: [Resin-interest] CanDI java.lang.StackOverflowError
The name of the first class is misleading (maybe Scheduled... would have
been better, it is executing scheduled tasks itself), Resin's scheduler
hasn't been involved in the configuration. But the issue is either the
same or we have two independent issues. If I remove the constructor
initialization by creating an empty constructor and use setter instead
of it, then the CanDI initialization does completes. However, if I add
@Startup annotation, so a class instance is actually created, then I
again receive StackOverflow.
Wesley Wu írta:
This could be a lazy init problem I think.
The scheduled tasks would be inited before some of other beans which
the tasks need.
I've met this before.
The workaround:
Inject the Injector into your task, no other webbeans.
When the task starts (run()), create webbeans instances via the injector.

2010/2/11 Hontvári József hontv...@flyordie.com:
I reduced the configuration to the minimum. It consists of a circular setter
dependency, and then a separate third constructor initialization which
refers to one of circular items. Both have to be present, otherwise
StackOverflow doesn't happen. I attached a configuration sample and a part
of the log file, logged on finer level.

initialization. Is there a way to debug this error? There is no stack

Can you send that section of the configuration file? It looks like it's
something to do with the resin:if like the test EL expression,
although it could also be the contents of the if.
Also, it's possible that adding a logger name= level=finer/ in the
resin section will show the stack trace.

[Resin-interest] bean tag and JMX
The doc for 4.0.x says that the resource tag is deprecated in favor of bean. If I try to setup JMX bean with bean then it doesn't work. It is registered as a CanDI object, but it is not registered in the MBean server. However, if I replace bean with resource then everything is correct, the JMX bean is shown by JConsole and the resin log also shows that it was registered. bean name=trafficSummary mbean-name=mireka:type=TrafficSummary type=mireka.filter.builtin.TrafficSummary / ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] prologue
I have included a prologue section in resin-web.xml, but it is not
accepted by Resin, see the log extract below.
I have't find a section dedicated to the prologue element in the
documentation, there are only indirect references to it. On the other
hand it is included in the default resin-xml (host-default / webapp) so
it mustn't be deprecated. This reference page contains almost the same
code as an example (prologue in resin-web.xml):
http://www.caucho.com/resin/reference/env-tags.xtp#class-loader
Where is prologue valid? Or where can I find this myself? For the 3.1
there is a Relax NG section in the configuration part of the
documentation, but not for 4.0.
