injecting env-entry into interceptor by @Resource does not work

[gunterze]

I use an Interceptor to initialize a POJO Service deployed as EJB Singleton:

public class LdapDicomConfigurationInterceptor {

    @Resource(name="ldapURL") String ldapURL;

    @Resource(name="userDN") String userDN;

    @Resource(name="password") String password;

    @Resource(name="baseDN") String baseDN;

    @PostConstruct

    void init(InvocationContext ctx) {

        LdapDicomConfiguration dc = (LdapDicomConfiguration) ctx.getTarget();

        LdapEnv env = new LdapEnv();

        env.setUrl(ldapURL);

        env.setUserDN(userDN);

        env.setPassword(password);

        try {

            dc.init(env, baseDN);

        } catch (Exception e) {

            throw new RuntimeException(e);

        }

    }

    @PreDestroy

    void close(InvocationContext ctx) {

        LdapDicomConfiguration dc = (LdapDicomConfiguration) ctx.getTarget();

        dc.close();

    }

}

But LdapDicomConfigurationInterceptor fields does not get injected.

Specifiying injection fields in ejb-jar.xml by

      <env-entry>

        <env-entry-name>password</env-entry-name>

        <env-entry-type>java.lang.String</env-entry-type>

        <env-entry-value>admin</env-entry-value>

        <injection-target>

          <injection-target-class>org.dcm4chee.conf.ldap.LdapDicomConfigurationInterceptor</injection-target-class>

          <injection-target-name>password</injection-target-name>

        </injection-target>

      </env-entry>

instead of @Resource works.

You have a mismatch between the ejb-name specified in the ejb-jar.xml (DicomConfiguration) and the annotated bean class implementation (LdapDicomConfigurationInterceptor). You can either change the ejb-jar.xml to use LdapDicomConfigurationInterceptor as the ejb-name or use the @javax.ejb.Singleton(name="DicomConfiguration") on the bean implementation class.

LdapDicomConfigurationInterceptor is not the EJB, but the Interceptor implementation.

I forgot to mention, that the lyfe-cyle methods in the inteptor class get invoked, so @PostConstruct and @PreDestroy annoations are processed properly - in opposite to the @Resource annotions.
