java ee - Deploy ejb-jar to be used by multiple wars (Glassfish) -

we have project creates jar file containing jpa entity , service classes access database. have number of different applications need make use of jar file. deploy jpa jar file ejb-jar , have other apps make use of via client jar file included in war.

along entity classes, our jpa project has generic service interface defined follows:

public interface genericservice {      <t> t create(t t) throws exception;      <t> t find(class<t> t, object id) throws exception;      <t> t update(t t);      list<?> findwithnamedquery(string queryname) throws exception;      list<?> findwithnamedquery(string queryname, int resultlimit) throws exception;      list<?> findwithnamedquery(string namedqueryname, map<string, object> parameters) throws exception;      list<?> findwithnamedquery(string namedqueryname, map<string, object> parameters, int resultlimit) throws exception;      <t> list<t> findwithnativequerylistresult(string sql, class<t> type) throws illegalargumentexception;      <t> list<t> findwithnativequerylistresult(string sql) throws illegalargumentexception;      <t> t findwithnativequerysingleresult(string sql, class<t> type) throws illegalargumentexception;      <t> t findwithnativequerysingleresult(string sql) throws illegalargumentexception; } 

which implemented in stateless session bean:

@stateless @ejb(name = "java:global/dataservice", beanname = "dataservice", beaninterface = dataservice.class) @local public class dataservice implements genericservice {      @persistencecontext(unitname = "database")     private entitymanager em;      protected entitymanager getentitymanager() {          return this.em;     }      @override     public <t> t create(t t) throws illegalargumentexception, entityexistsexception, persistenceexception {          em.persist(t);         return t;     }      .... etc .... } 

we use maven our builds , set generate client jar:

  <plugin>     <groupid>org.apache.maven.plugins</groupid>     <artifactid>maven-ejb-plugin</artifactid>     <version>2.3</version>     <configuration>       <!-- false default -->       <generateclient>true</generateclient>       <ejbversion>3.1</ejbversion>     </configuration>   </plugin> 

and have set empty ejb-jar.xml file:

<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" version="3.1" metadata-complete="false">     <enterprise-beans>     </enterprise-beans> </ejb-jar> 

the client file generated used dependency in our war projects:

<dependency>     <groupid>my.package</groupid>     <artifactid>data-model</artifactid>     <version>1.0</version>     <classifier>client</classifier> </dependency> 

when deploy both ejb-jar , war files, looks okay. when try access service/entity classes war application, get:

obviously, there's no method defined on our batch entity class __jr_selector__, coming from? how debug this?

any advice on how we're setting ejb-jar and/or war use appreciated well.

we deploying glassfish 3.1.2.2 server.
