java - Jersey jdbc @resource not working -

i'm trying have simple jersey based jaxrs listener, running on existing tomcat 7.0.57. tomcat has global config in context.xml jdbc datasource, want use.

my problem can't resource resolve via @resource annotation.

heres simple test example

@path("/") public class testjersey {     @resource(name = "jdbc/default")     private datasource dsa;      @resource(name = "java:comp/env/jdbc/default")     private datasource dsb;      @resource(lookup = "java:comp/env/jdbc/default")     private datasource dsc;      @resource(mappedname="jdbc/default")     private datasource dsd;      @get     @produces("text/plain")     public string test() throws namingexception {         stringbuffer ret = new stringbuffer();         ret.append("a: " + dsa + "\n");         ret.append("b: " + dsb + "\n");         ret.append("c: " + dsc + "\n");         ret.append("d: " + dsd + "\n");                 datasource ds1 =                (datasource) initialcontext.dolookup("java:comp/env/jdbc/default");         ret.append("1: " + ds1 + "\n");         return ret.tostring();     } } 

this test app returns following

a: null b: null c: null d: null 1: org.apache.tomcat.jdbc.pool.datasource@1518c95{connectionpool[d..... 

so jdbc connection configured, , can accessed explicit dolookup, why can't working @resource annotation?

my apps web.xml contains

<servlet>     <servlet-name>test</servlet-name>     <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class>     <init-param>         <param-name>jersey.config.server.provider.packages</param-name>         <param-value>com.test</param-value>     </init-param> </servlet>  <servlet-mapping>     <servlet-name>test</servlet-name>     <url-pattern>/*</url-pattern> </servlet-mapping> 

i've spend time searching i'm doing wrong can't find it. i've read posts suggesting adding things following web.xml snippets, haven't helped

  <resource-ref>       <description>db connection</description>       <res-ref-name>jdbc/default</res-ref-name>       <res-type>javax.sql.datasource</res-type>       <res-auth>container</res-auth>   </resource-ref> 

for completeness, maven dependencies jersey:

<dependency>     <groupid>org.glassfish.jersey.containers</groupid>     <artifactid>jersey-container-servlet</artifactid>     <version>2.19</version> </dependency> 

it looks peeskillet right needing level of cdi.

i'll explain had add, kind of jumps away lot of instructions found.

first, need cdi manager, weld 1 of need dependency in our pom that

<dependency>     <groupid>org.jboss.weld.servlet</groupid>     <artifactid>weld-servlet</artifactid>     <version>2.2.15.final</version> </dependency> 

it need logging dependency, avoid warnings or logging, logs going normal java util logging

<dependency>     <groupid>org.slf4j</groupid>     <artifactid>slf4j-jdk14</artifactid>     <version>1.7.12</version> </dependency> 

only isn't enough, jersey apparently uses hk, not cdi need adapter.

<dependency>     <groupid>org.glassfish.jersey.containers.glassfish</groupid>     <artifactid>jersey-gf-cdi</artifactid>     <version>2.6</version> </dependency> 

then adapter seems have broken dependency need add 1 more avoid 2 page stack trace each request.

<dependency>     <groupid>javax.transaction</groupid>     <artifactid>javax.transaction-api</artifactid>     <version>1.2</version> </dependency> 

so have code in place, need 1 last thing make work.

you need empty web-inf/beans.xml. don't quite follow why though.

some sites state need meta-inf/context.xml entry, didn't find needed that, perhaps injecting custom classes?

hopefully helps else
