I have a method that can be called if the person has a specific role and they are associated with a particular group in JIRA. Since the groups in JIRA are dynamic, I can't have a role per JIRA group.
#DeclareRoles({
FileServerRoles.FILE_ADDER,
FileServerRoles.FILE_ADDER_ALL,
FileServerRoles.FILE_VIEWER,
FileServerRoles.FILE_VIEWER_ALL})
public final class FileServerRoles {
/**
* A user that can add files to the system.
*/
public static final String FILE_ADDER = "file-adder";
/**
* A user that can add any files to the system.
*/
public static final String FILE_ADDER_ALL = "file-adder-all";
/**
* A user that can view files in the system.
*/
public static final String FILE_VIEWER = "file-viewer";
/**
* A user that can view all files in the system.
*/
public static final String FILE_VIEWER_ALL = "file-viewer-all";
}
I am declaring all of the roles using #DeclareRoles.

I have had no problem with any of the roles when that are referenced in #RolesAllowed. I have also tried moving the roles declaration into web.xml. There aren't many references to the error on google.
Has anyone seen this? What was your solution?
I was receiving the same "No mapping available for role reference" error when calling the isCallerInRole(roleName) method within an EJB in GlassFish 3.1. What fixed it for me was adding the appropriate #DeclareRoles annotation to my EJB. If the role name passed to isCallerInRole is not in #DeclareRoles, an IllegalStateException gets thrown. I'm not sure how security works within a decorator but #DeclareRoles was the key for me.
Here is a simple example:
#Stateless
#LocalBean
#DeclareRoles({"user", "admin"})
public class ExampleEJB {
#Resource
private SessionContext sessionContext;
public boolean isUserInRole(String roleName) {
return sessionContext.isCallerInRole(roleName);
}
}

I have a form that based on collected information generates a report. I have multiple sources from which to generate reports, but the form for them is the same. I tried to implement strategy pattern using an interface implementing report generator services, but that led to wicket complaining about serialization issues of various parts of the report generator. I would like to solve this without duplicating the code contained in the form, but I have not been able to find information on dynamic injection with #SpringBean.
Here is a rough mock up of what I have
public class ReportForm extends Panel {
private IReportGenerator reportGenerator;
public ReportForm(String id, IReportGenerator reportGenerator) {
super(id);
this.reportGenerator = reportGenerator;
final Form<Void> form = new Form<Void>("form");
this.add(form);
...
form.add(new AjaxButton("button1") {
private static final long serialVersionUID = 1L;
#Override
protected void onSubmit(AjaxRequestTarget target)
{
byte[] report = reportGenerator.getReport(...);
...
}
});
}
}
If I do it this way, wicket tries to serialize the concrete instance of reportGenerator. If I annotate the reportGenerator property with #SpringBean I receive Concrete bean could not be received from the application context for class: IReportGenerator
Edit: I have reworked implementations of IRerportGenerator to be able to annotate them with #Component and now I when I use #SpringBean annotation I get More than one bean of type [IReportGenerator] found, you have to specify the name of the bean (#SpringBean(name="foo")) or (#Named("foo") if using #javax.inject classes) in order to resolve this conflict. Which is exactly what I don't want to do.
I think the behavior you're trying to achieve can be done with a slight workaround, by introducing a Spring bean that holds all IReportGenerator instances:
#Component
public class ReportGeneratorHolder {
private final List<IReportGenerator> reportGenerators;
#Autowired
public ReportGeneratorHolder(List<IReportGenerator> reportGenerators) {
this.reportGenerators = reportGenerators;
}
public Optional<IReportGenerator> getReportGenerator(Class<? extends IReportGenerator> reportGeneratorClass) {
return reportGenerators.stream()
.filter(reportGeneratorClass::isAssignableFrom)
.findAny();
}
}
You can then inject this class into your Wicket page, and pass the desired class as a constructor-parameter. Depending on your Spring configuration you might need to introduce an interface for this as well.
public class ReportForm extends Panel {
#SpringBean
private ReportGeneratorHolder reportGeneratorHolder;
public ReportForm(String id, Class<? extends IReportGenerator> reportGeneratorClass) {
super(id);
IReportGenerator reportGenerator = reportGeneratorHolder
.getReportGenerator(reportGeneratorClass)
.orElseThrow(IllegalStateException::new);
// Form logic omitted for brevity
}
}
As far as I am able to find, looking through documentation and even the source for wicket #SpringBean annotation, this isn't possible. The closest I got is with explicitly creating a proxy for a Spring bean based on class passed. As described in 13.2.4 Using proxies from the wicket-spring project chapter in Wicket in Action.
public class ReportForm extends Panel {
private IReportGenerator reportGenerator;
private Class<? extends IReportGenerator> classType;
private static ISpringContextLocator CTX_LOCATOR = new ISpringContextLocator() {
public ApplicationContext getSpringContext() {
return ((MyApplication)MyApplication.get()).getApplicationContext();
}
};
public ReportForm(String id, Class<? extends IReportGenerator> classType) {
super(id);
this.classType = classType;
final Form<Void> form = new Form<Void>("form");
this.add(form);
...
form.add(new AjaxButton("button1") {
private static final long serialVersionUID = 1L;
#Override
protected void onSubmit(AjaxRequestTarget target)
{
byte[] report = getReportGenerator().getReport(...);
...
}
});
}
private <T> T createProxy(Class<T> classType) {
return (T) LazyInitProxyFactory.createProxy(classType, new
SpringBeanLocator(classType, CTX_LOCATOR));
}
private IReportGenerator getReportGenerator() {
if (reportGenerator = null) {
reportGenerator = createProxy(classType);
}
return reportGenerator;
}
}
I am running jee-2019-06 version of Eclipse. Here is my Model-Bean-Facade structure:
I am not including getters/setters for brevity.
My Identifiable:
/** Identifiable interface for Entities; used for DAO - Service transitions. */
public interface Identifiable<T extends Serializable> extends Serializable {
public T getId(); // identifiable field
public String getTitle(); // user friendly name (maybe different from actual entity's name)
public String getName(); // every entity has a name
public String getDescription(); // every entity should have a description
}
My Abstract Bean:
public abstract class AbstractBean<T extends Identifiable<?>> {
protected final transient Logger log = Logger.getLogger(this.getClass());
private final Class<T> clazz;
private T model;
public AbstractBean(final Class<T> clazz) {
this.clazz = clazz;
}
protected T createInstance() {
try {
return this.clazz.newInstance();
} catch (InstantiationException | IllegalAccessException e) {
this.log.error("[" + this.getClass().getSimpleName() + ".createInstance()] : Error : {} {}", e.getMessage(), e);
return null;
}
}
protected AbstractFacade<T> getFacade() {
return null;
}
}
My Abstract Facade:
#Transactional
public abstract class AbstractFacade<T extends Identifiable<?>> {
protected final transient Logger log = Logger.getLogger(this.getClass());
protected final Class<T> clazz;
public AbstractFacade(final Class<T> clazz) {
this.clazz = clazz;
}
}
My Bean:
#Named
#ViewScoped
public class CarBean extends AbstractBean<Car> {
#Inject
private CarFacade facade;
public CarBean(){
super(Car.class);
}
#Override
public CarFacade getFacade() {
return this.facade;
}
}
My AbstractEntity:
#MappedSuperclass
public abstract class AbstractEntity implements Identifiable<Integer> {
private Integer id;
private String name;
private String description;
public AbstractEntity() {
}
}
My Entity:
public class Car extends AbstractEntity {
public Car() {
}
}
I have no problems in showing the value to the user.
I have problems in validation and hyperlink in Eclipse:
<h:outputText value="#{carBean.model.name}" />
Facelet validator cannot validate name of model. It yellow underlines name. Also, I cannot Ctrl + click to activate hyperlink on name.
I saw on another developer's eclipse that both of my problems were not issues at all. I compared all the tools installed in both Eclipses and could not find anything relevant.
My question: what tools do I have to install or what settings/adjustments am I missing?
Please note: I do not want to disable the validator and I want to be able to hyperlink fields in facelet so that I will access the field using Ctrl + click.
Thank you.
I am using Spring Data MongodB 1.4.2.Release version. For Spring Data MongoDB, I have created the custom repository interface and implementation in one location and create custom query function getUsersName(Users users).
However I am still getting below exception:

}
The query method declaration in your repository interface is invalid. As clearly stated in the reference documentation, query methods need to start with get…By, read_By, find…By or query…by.
With custom repositories, there shouldn't be a need for method naming conventions as Oliver stated. I have mine working with a method named updateMessageCount
Having said that, I can't see the problem with the code provided here.
I resolved this issue with the help of this post here, where I wasn't naming my Impl class correctly :
No property found for type error when try to create custom repository with Spring Data JPA
I am having issues with RPC calls and GWT. Essentially, I have a Person class (common code between client and server) that is created in the client side web code, sent to the server code via an RPC call, and then saved to a DB (OrientDB). I have verified that the following work:
RPC call - I am able to send info to the server and retrieve info from the server
save to DB - have verified that a Person object is saved to the DB
Where I am having issues is the transfer of the POJO from the client to the server. I have verified that the POJO's properties are intact right before it is sent to the server, however, the object passed to the server contains null values for all properties. Essentially, the class is transferred but the information is not. It then saves to the DB, but obviously without any relevant information contained within it.
I will copy what I feel is relevant below, please let me know what else I can provide to make this problem easier to identify. Note these are still in a testing state, so mind the comments :)
Any idea why my POJO's information is being lost in translation?
Person object, followed by the abstract class it inherits from:
public class Person extends org.matesweb.shared.AbsPerson implements Serializable
{
#Id
private String id; // DON'T CREATE GETTER/SETTER FOR IT TO PREVENT THE CHANGING BY THE USER APPLICATION,
// UNLESS IT'S NEEDED
//sets new user details

/*this method adds a new purchase to the purchases variable*/
/* public void addPurchase(float price, String description)

return groups;
}
public void setGroups(org.matesweb.shared.Group[] gro)
{
groups = gro;
}
public org.matesweb.shared.Purchase[] getPurchases()
{
return purchases;
}
public void setPurchases(org.matesweb.shared.Purchase[] purch)
{
purchases = purch;
}
}
Service
package org.matesweb.client;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import org.matesweb.shared.Person;
#RemoteServiceRelativePath("peopleService")
public interface PeopleService extends RemoteService {
//test services
String stringTest(String outgoingString);

//production services
String savePerson(Person p);
}
ServiceAsync
import com.google.gwt.user.client.rpc.AsyncCallback;
import org.matesweb.shared.Person;
public interface PeopleServiceAsync
{
//tests
void stringTest(String outgoingString, AsyncCallback<String> incomingString);
void getPerson(String persId, AsyncCallback<Person> retPerson);
//production services
void savePerson(Person p , AsyncCallback<String> st);
}
ServiceImpl call for this particular method:
//production calls
#Override
public String savePerson(Person p) {
String st = ioObj.saveObj(p);
if(st.equals("Success")){
return "Your information has been saved successfully!";
} else{
return "Something has gone wrong on our end... Sorry! Error:<br /> " + st;
}
}
and finally, the call itself
private static void savePerson(Person p)
{
// Initialize the service proxy.
if (peopleSvc == null) {
peopleSvc = GWT.create(PeopleService.class);
}
//resets status
st="";
// Set up the callback object.
AsyncCallback<String> callback = new AsyncCallback<String>() {
#Override
public void onFailure(Throwable caught) {
st = caught.getMessage();
Label stLabel= new Label(st);
personTable.setWidget(3,1,stLabel);
}
#Override
public void onSuccess(String result) {
st = result;
HTML stLabel= new HTML(st);
joinPanel.add(stLabel);
}
};
// Make the call to the people service.
peopleSvc.savePerson(p, callback);
}
I was able to fix this issue by implementing GWT's IsSerializable interface. I also removed the Serializable interface from the Person class and let it inherit IsSerializable from the abstract class it inherits from.
I need to pass a class object through the gwt rpc connection as a generic but it seems that rpc does not cooperate with it. The class is serialized using the java.io.Serializable. I have checked it using the gwt IsSerializable but i still have the error.

The paradox is that when i am running my application through the eclipse plugin everything works fine. Could anyone help me please? I have checked to fix the problem through the DTO solution without any success. Moreover i have tried to implement a CustomFieldSerializer as Google suggests without any success too.
Thanks in advance,
Stefanos Antaris
P.S. Sorry for the huge post :-)
Well the problem is that you trying to transport a Class object over the network. I have no idea why it is working in dev mode (I've tried it on local project and it failed), but it shouldn't work. You have to use something else instead of Class name for example String, which will contain a name of class. Theoretically it can work if you create CustomFieldSerializer for Class, but using String instead of Class will be easier.
Classes with persistence annotations can work well on the server side, but if you want to pass its data to the client you must create a plain java serializable class to transport data from server to client.
As noted in the previous answer, persistence annotations are not supported in the client side, as they cannot be translated to equivalent javascript code (and it makes sense since the client doesn't have the responsability of persistence).
It could be that the persistence-related annotations in MySource.java make it implossible to translate to javascript. Try removing the annotations to see if it's related. Also make sure that MySource.java is in a package declared as translatable in the module xml file ("source" element).
Try using implements Serializable for defining you class.
I mean like this:
public class AndroidSource extends MySource implements Serializable{
public AndroidSource() {
super();
}
}
Your RPC Services must deal just with Serializable Objects. Domain classes are not translatable to JavaScript So GWT can't send and receive via network (RPC Protocole) such objects. You need to create DTO classes (wich shadows domain class) implementing java.io.Serializable and then reconfigure all your RPC Service to use in input DTOs and output DTOs. Good Luck for your project.
