I have been on this issue for atleast 2 weeks now. Trying to use Wicket with
EJB. This occurs when I use @EJb for either a stateless or stateful bean .
*My code below
The webpage which has the EJB as a variable*
public class PartnersZipCode extends PrescientTemplateOriginalPage{
@EJB(name = "ejb/publishZipCodes")
transient private PublishZipCodes partnerInterests;
@EJB
transient private ProspectivePartners marketPlace;
private String sessionZip="sessionZip";
private String sessionEmail="sessionEmail";
private String nameFromSession;
private String dbKeys="dbKeys";
private Vector<Integer> forkeys;
private Form zipCodeFormOfInterest;
private Label partnerOne;
private Label partnerTwo;
private Label interestedZips;
private Collection listOfZips;
public PartnersZipCode() {
zipCodeFormOfInterest=new Form("zipCodeFormOfInterest");
partnerOne=new Label("partnerOne");
partnerTwo=new Label("partnerTwo");
interestedZips=new Label("interestedZips");
zipCodeFormOfInterest.add(partnerOne);
zipCodeFormOfInterest.add(partnerTwo);
zipCodeFormOfInterest.add(interestedZips);
add(zipCodeFormOfInterest);
nameFromSession=(String) getSession().getAttribute(sessionEmail);
forkeys= (Vector<Integer>) getSession().getAttribute(dbKeys);
partnerInterests.publishZip(nameFromSession,listOfZips=(Collection)
getSession().getAttribute(sessionZip));
}
}
*The EJB Class*
@ManagedBean
@JMSConnectionFactoryDefinition(
name="java:app/jms/ZipCodesConnectionFactory"
)
public class PublishZipCodes {
Message message;
Session session;
JMSProducer messageProducer;
Collection nextZipCode;
//@Resource(lookup = "java:comp/jms/ZipCodesConnectionFactory")
// ConnectionFactory connectionFactory;
@Resource(lookup = "jms/ZipCodes")
Topic topic;
@EJB
StartUpSingleton bean;
@Inject
@JMSConnectionFactory(value ="jms/ZipCodesConnectionFactory")
JMSContext connection;
public PublishZipCodes() {
}
@PostConstruct
public void publish() {
if(connection==null){
connection=bean.getConnection();
}
// messageProducer=connection.createProducer();
nextZipCode=new ArrayList<>();
if(nextZipCode.isEmpty()){
}
messageProducer=connection.createProducer();
message= connection.createTextMessage(
Arrays.deepToString(nextZipCode.toArray()) );
messageProducer.send(topic,message);
}
public void closeConn(){
connection.close();
}
public JMSContext getConnection() {
return connection;
}
public void setConnection(JMSContext connection) {
this.connection = connection;
}
public void publishZip(String toString, Collection arrayList) {
nextZipCode=arrayList;
if(messageProducer==null){
messageProducer=connection.createProducer();
}
HashMap maptoString=new HashMap();
maptoString.put(toString,nextZipCode.toArray());
message= connection.createTextMessage((String)
maptoString.keySet().stream().map(key -> key + "=" +
maptoString.get(key)).collect(Collectors.joining(", ", "{", "}")));
messageProducer.send(topic,message);
}
}
*The continuous and frustrating error below*
