I have a java class that I want to import into RHDM 7.9.0. It imports but a warning message is displayed that the class cannot be parsed. Once imported I am able to view it in the Source view but when I try to open the Model View it shows the message "Java file could not be parsed, it won’t be possible to open the Editor tab, use the Source tab instead."
Is this normal or is there something wrong with my Java file?

I found the answer to my question. I imported the class into the com.myspace package but the class definition had com.cdm_testing as the package. Once I changed the package in the Source view it became available in the Model view.

i'm starting with Rest and don't have no idea how to implement it properly. I got an exercise: i must implement a Rest-Client with the RestClient-API from javax.ws.rs standard library and i tried by using the code below, but i'm getting a null pointer exception. But the resource are there and when i try directly from the browser (http://localhost:8080/sep/rest/customers/112). Now my question how can i do it properly. Some constraints, i must use XML (not JSON) for the Data-support.
Hier my client-code:
public Response createCustomer(Customer customer){
log.info("Starting: Rest Create a Customer with Name: " + Customer.class.getName());
this.customerWebTarget = this.client.target(URL);
Response response = this.customerWebTarget.request().
buildPost(Entity.entity(customer, MediaType.APPLICATION_XML)).invoke();
log.info("Ending: Rest Create a Customer with Name: " + response.getEntity().getClass().getName());
return response;
}
CustomerResource-Code:
#Path("customers")
public class CustomerResource implements IAllowedMethods<Customer> {
private static final long serialVersionUID = -6367055402693237329L;
private Logger logger = Logger.getLogger(CustomerResource.class.getName());
#Inject
private CustomerService service;
public CustomerResource() {
logger.info("create of instance " + this.getClass().getName());
}
#Override
#GET
#Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public Response get() {
List<Customer> list = service.loadAll(Customer.FINDALL, Customer.class);
if (list != null && !list.isEmpty()) {
ResponseCustomerList responseList = new ResponseCustomerList();
responseList.setList(list);
return Response.ok(responseList).build();
}
return Response.status(Status.NOT_FOUND).build();

Instead of response.getEntity(), use response.readEntity(String.class) to get the data as a String. If you want to deserialize it to a POJO, then just pass that class to the readEntity.
Also you should make sure to check the status code (response.getStatus()) to make sure it's a success status.
I'm using some JavaFX properties in my app:
#Entity(name = "Klanten")

})
public class Klant implements Serializable {
#Id

private int klantId;
#Transient
private final SimpleStringProperty naam = new SimpleStringProperty();
//private String naam;
//private String straat;
#Transient
private final SimpleStringProperty straat = new SimpleStringProperty();
private String telefoon;
private String huisnummer;

private String woonplaats;

private String postcode;

However when I let JPA generate my database, the column "naam" and "straat" aren't generated. I get no error. How can I resolve this?
I tried all the things listed here:
Possible solution 1
Possible solution 2
These didn't work.
You can try to use regular properties and then have another get method which returns a new SimpleStringProperty, i.e.:
public StringProperty naamProperty() {
return new SimpleStringProperty(naam);
}
public StringProperty straatProperty() {
return new SimpleStringProperty(straat);
}
I am trying to use a lambda to average a field over another grouped field. It fails and says it can't find field price. It does find the tradeMinutes field without problem. This would lead me to believe that it does now the correct class.

I am new at GWT and I have an application which has the following class:
package evaluation.system.shared;
import java.io.Serializable;
import com.google.gwt.user.client.rpc.IsSerializable;
public class Evaluation implements Serializable, IsSerializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String evaluatorRID;
private String fName;
private String lName;
private double score;
public Evaluation() {
}
public String getEvaluatorRID() {
return evaluatorRID;
}
public void setEvaluatorRID(String evaluateeRID) {
this.evaluatorRID = evaluateeRID;
}
public String getfName() {
return fName;
}
public void setfName(String fName) {
this.fName = fName;
}
public String getlName() {
return lName;
}
public void setlName(String lName) {
this.lName = lName;
}
public double getScore() {
return score;
}
public void setScore(double score) {
this.score = score;
}
public Evaluation(String evaluatorRID, String fName, String lName,
double score) {
this.evaluatorRID = evaluatorRID;
this.fName = fName;
this.lName = lName;
this.score = score;
}
}
and each time I run the application the get the following error:
[ERROR] [evaluationsystem] Line 10: No source code is available for
type evaluation.system.shared.Evaluation; did you forget to inherit a
required module?
And as you can see line 10 is the beginning of the class.
Your help is appreciated!
So I found what the problem is, basically its the class name. I am not sure if GWT was unable to recognize the class Evaluation.java because "evaluation" is also in the package name...
All I know is that it occured to me that this could be causing the problem and when I changed the name it worked perfectly!
