Java EE 6 Enterprise Application: Warning "Unsatisfied dependency: no bean matches the injection point" when injecting a bean
cdi, ear, netbeans, servlets
Solution
I solved the problem: I've just forgotten the beans.xml in the EJB-Project. One beans.xml in an EAR-Project ist not enough...
Problem
I have created a fresh new Java EE 6 Enterprise-Application in Netbeans 7.2. So I have three Projects: - EAR - EJB - WAR In the EJB-Project, I have created a simple Bean: ``` package de.aidaorga.test; import javax.ejb.LocalBean; import javax.ejb.Stateless; @Stateless @LocalBean public class NewSessionBean2343 { } ``` In the WAR-Project, I have created a blank beans.xml in the folder "Web Pages\WEB-INF": ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"> </beans> ``` And I have also created a simple Servlet: ``` import de.aidaorga.test.NewSessionBean2343; import java.io.IOException; import javax.ejb.EJB; import javax.inject.Inject; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; @WebServlet(name = "NewServlet2343", urlPatterns = {"/NewServlet2343"}) public class NewServlet2343 extends HttpServlet { @Inject NewSessionBean2343 newSessionBean2343_1; protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } @Override public String getServletInfo() { return "Short description"; } } ``` Now, Netbeans shows me a Warning "Unsatisfied dependency: no bean matches the injection point" for the field "newSessionBean2343_1" annotated with "@Inject". At deploy time, I get the following Excpetion: ``` Schwerwiegend: Exception while loading the app Schwerwiegend: Exception while loading the app : WELD-001408 Unsatisfied dependencies for type [NewSessionBean2343] with qualifiers [@Default] at injection point [[field] @Inject NewServlet2343.newSessionBean2343_1] org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [NewSessionBean2343] with qualifiers [@Default] at injection point [[field] @Inject NewServlet2343.newSessionBean2343_1] at org.jboss.weld.bootstrap.Validator.validateInjectionPoint(Validator.java:311) at org.jboss.weld.bootstrap.Validator.validateInjectionPoint(Validator.java:280) at org.jboss.weld.bootstrap.Validator.validateBean(Validator.java:143) at org.jboss.weld.bootstrap.Validator.validateRIBean(Validator.java:163) at org.jboss.weld.bootstrap.Validator.validateBeans(Validator.java:382) at org.jboss.weld.bootstrap.Validator.validateDeployment(Validator.java:367) at org.jboss.weld.bootstrap.WeldBootstrap.validateBeans(WeldBootstrap.java:380) at org.glassfish.weld.WeldDeployer.event(WeldDeployer.java:199) at org.glassfish.kernel.event.EventsImpl.send(EventsImpl.java:128) at org.glassfish.internal.data.ApplicationInfo.start(ApplicationInfo.java:313) at com.sun.enterprise.v3.server.ApplicationLifecycle.deploy(ApplicationLifecycle.java:461) at com.sun.enterprise.v3.server.ApplicationLifecycle.deploy(ApplicationLifecycle.java:240) at org.glassfish.deployment.admin.DeployCommand.execute(DeployCommand.java:389) at com.sun.enterprise.v3.admin.CommandRunnerImpl$1.execute(CommandRunnerImpl.java:348) at com.sun.enterprise.v3.admin.CommandRunnerImpl.doCommand(CommandRunnerImpl.java:363) at com.sun.enterprise.v3.admin.CommandRunnerImpl.doCommand(CommandRunnerImpl.java:1085) at com.sun.enterprise.v3.admin.CommandRunnerImpl.access$1200(CommandRunnerImpl.java:95) at com.sun.enterprise.v3.admin.CommandRunnerImpl$ExecutionContext.execute(CommandRunnerImpl.java:1291) at com.sun.enterprise.v3.admin.CommandRunnerImpl$ExecutionContext.execute(CommandRunnerImpl.java:1259) at com.sun.enterprise.v3.admin.AdminAdapter.doCommand(AdminAdapter.java:461) at com.sun.enterprise.v3.admin.AdminAdapter.service(AdminAdapter.java:212) at com.sun.grizzly.tcp.http11.GrizzlyAdapter.service(GrizzlyAdapter.java:179) at com.sun.enterprise.v3.server.HK2Dispatcher.dispath(HK2Dispatcher.java:117) at com.sun.enterprise.v3.services.impl.ContainerMapper$Hk2DispatcherCallable.call(ContainerMapper.java:354) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:195) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:860) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:757) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:1056) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:229) at com.sun.grizzly.DefaultProtocolChain.executeProtocolFilter(DefaultProtocolChain.java:137) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:104) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:90) at com.sun.grizzly.http.HttpProtocolChain.execute(HttpProtocolChain.java:79) at com.sun.grizzly.ProtocolChainContextTask.doCall(ProtocolChainContextTask.java:54) at com.sun.grizzly.SelectionKeyContextTask.call(SelectionKeyContextTask.java:59) at com.sun.grizzly.ContextTask.run(ContextTask.java:71) at com.sun.grizzly.util.AbstractThreadPool$Worker.doWork(AbstractThreadPool.java:532) at com.sun.grizzly.util.AbstractThreadPool$Worker.run(AbstractThreadPool.java:513) at java.lang.Thread.run(Thread.java:722) ``` Why do I get this warning and how do I get rid of it?
