I followed the walkthrough for setting up a custom authenticator spi for keycloak (version 4.8.3). I pretty much only use the example code i got from here. I only changed the pom so i could compile the project and deploy it with mvn clean install wildfly:deploy. And it works ... I can configure the new authentication flow in keycloak, update the Browser Flow and set the required actions. But if i want to use the new Authentication with my application i get the following message: Invalid username or password. And in the console i get the following output:
17:12:20,721 WARN [org.keycloak.events] (default task-1) type=REFRESH_TOKEN_ERROR, realmId=master, clientId=security-admin-console, userId=null, ipAddress=127.0.0.1, error=invalid_token, grant_type=refresh_token, client_auth_method=client-secret

I looked up the file DefaultAuthenticationFlow.java:194 on github and it seems to be a RuntimeException:
throw new RuntimeException("Unable to find factory for AuthenticatorFactory: " + model.getAuthenticator() + " did you forget to declare it in a META-INF/services file?");
I dont really know what to do about that. I have the META-INF/services from the example project included.
any idea what the problem might be here?
Update:
Here my auth. flow settings:
Bindings ยป Browser Flow: is set to test
Update:
I used something like this for my own authenticator.
public class TestAuthenticator extends UsernamePasswordForm {

For who wants an example:
https://github.com/mfandre/KeycloakSPI/
This example creates an SPI to user storage... The idea is similar to authenticate the user in LDAP but in this example, we will authenticate in a RestAPI and bring the user to the keycloak!

I am recently tasked with migrating an existing application (using myfaces 2 and primefaces 5) from Tomcat(JDK 1.7) to JBoss(openJDK 1.8). Ultimately, the app was able to startup and I managed to reach the login page and logged in successfully.
Once logged in, the SidebarBacking class will be called. This SidebarBacking class extends a AbstractBean class (with no scope defined) and injects a AppContextBean for the menu.

On successfully login, I am able to see the side menu and main page with all the table of data retrieved from the database.
The issue is when I click on any of the menu link, it will throw the following exceptions.

I read that this indicates that the scope already expired when you access the page.
I am able to resolve the exception if I add a scope to the AbstractBean class, however this will cause a problem.
Whenever any data is updated, although the database is updated successfully, data across the whole website will still not be refreshed to its latest information. The data remain in the last state when they are first retrieved. Only when I logged out and logged in again, then only will the new data be reflected.
package com.myapp.pkg2.web.mbean;
#ManagedBean(name = "abstractBean")
#SessionScoped
public class AbstractBean implements Serializable
{
....
I also tried playing around with a few variation for p:commandButton but with no success
<p:commandButton id="btnAssign" value="Assign" action="#{myInbox.assignWork}" update="#all" />
<p:commandButton id="btnAssign" value="Assign" action="#{myInbox.assignWork}" update="#form" />
<p:commandButton id="btnAssign" value="Assign" action="#{myInbox.assignWork}" update="dataTable" />
<p:commandButton id="btnAssign" value="Assign" action="#{myInbox.assignWork}" update=":form:dataTable" />
<p:commandButton id="btnAssign" value="Assign" action="#{myInbox.assignWork}" process="#all" update="dataTable" />
The problem seem to be due to the scope that was added to the AbstractBean as all the backing beans (e.g. MyInboxBacking) extends the AbstractBean class. Therefore, even if they have their own scope (e.g. #RequestScoped, #ViewScoped), they will not take effect due to the parent class's scope.
As such, how can I remove the scope from the AbstractBean without causing the exception stated or is there any way I can refresh the data even with the #Sessionscoped?
I have created a piece of code for generating and downloading an excel file in servlet. The code is provided below:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String act = request.getParameter("act").toLowerCase();
RequestDispatcher rd = request.getRequestDispatcher("sqleditor.jsp");
try {
if(act.equalsIgnoreCase("exec")) {
String uqry = request.getParameter("isql");
if ( !uqry.isEmpty() ) {
qp = new queryProcessor(uqry);
mp = qp.getResultSet();
request.setAttribute("result",mp);
rd.forward(request, response);
} else {
ERROR_MSG = "Please enter a query";
request.setAttribute("errormsg", ERROR_MSG);
rd.forward(request, response);
}
} else if (act.equalsIgnoreCase("excel")) {
String uqry = request.getParameter("isql");
if ( !uqry.isEmpty() ) {
try {
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "attachment; filename=\"" + FILENAME + "\"");
initExcelfile(response.getOutputStream());
} catch (Exception evar1) {
request.setAttribute("errormsg", evar1.getMessage());
rd.forward(request, response);
}
System.out.println("File downloaded at client successfully");
}
}
} catch (AppException evar2) {
request.setAttribute("errormsg", evar2.getmessage());
rd.forward(request, response);
} catch (SQLException evar3) {
request.setAttribute("errormsg", evar3.getMessage());
rd.forward(request, response);
} catch (NullPointerException evar4) {
request.setAttribute("errormsg", evar4.getMessage());
rd.forward(request, response);
} catch (FileNotFoundException evar5) {
request.setAttribute("errormsg", evar5.getMessage());
rd.forward(request, response);
} catch (Exception evar6) {
request.setAttribute("errormsg", evar6.getMessage());
rd.forward(request, response);
}
}
private void initExcelfile(ServletOutputStream outputStream) {
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("Datatypes");
Object[][] datatypes = {
{"Datatype", "Type", "Size(in bytes)"},
{"int", "Primitive", 2},
{"float", "Primitive", 4},
{"double", "Primitive", 8},
{"char", "Primitive", 1},
{"String", "Non-Primitive", "No fixed size"}
};
int rowNum = 0;
System.out.println("Creating excel");
for (Object[] datatype : datatypes) {
Row row = sheet.createRow(rowNum++);
int colNum = 0;
for (Object field : datatype) {
Cell cell = row.createCell(colNum++);
if (field instanceof String) {
cell.setCellValue((String) field);
} else if (field instanceof Integer) {
cell.setCellValue((Integer) field);
}
}
}
System.out.println("Workbook Created");
try {
workbook.write(outputStream);
} catch (IOException e) {
e.printStackTrace();
}
}
But when I move the initExcelfile() method to a separate class file and invoke the method from there I receive the below error:

Could you please let me know what I am missing here due to which I am encountering this error.
Based on the stacktrace, it looks like you are first doing this:
initExcelfile(response.getOutputStream())
which is throwing an exception. Then in the exception handler you appear to be trying to redirect to a JSP to produce an error message. Unfortunately, that is failing because:
the JSP is going to call getWriter() on the response object to find the place to send its output,
you have already called getOutputStream() on the response object, and
you cannot call both getWriter() and getOutputStream() on the same Response object ... or you will get an IllegalStateException!
If you are going to write your spreadsheet directly to the output, you CANNOT redirect to a JSP in the event of failure. Even if the servlet framework allowed it (it doesn't!), you would be liable to get a partial spreadsheet with an error page tacked on the end. The user's web browser wouldn't be able to make sense of that.
There are two alternatives:
Get rid of that attempted redirect in the case where you get an exception while generating the spreadsheet.
Keep the redirect, but change your code so that you prepare and buffer the spreadsheet. Only open the response output stream after you have successfully generated the spreadsheet.
There is also the question of what is causing the exception in the first place. There are no obvious clues that I can see, so you will need to debug that yourself. (For example, you could attach a debugger and set a breakpoint in the exception handler, and look at the caught exception's class, message and callstack.)

I've search a lot of forum but it seems none is working.. TIA
I was using Hibernate 3, now I'm migrating to Hibernate 5, and some problems occurred (of course).
I have several DAO objects that are stored via Hibernate, and some of them have parameter/field/column "modified" which is automatically updated to current time on each save/update in Hibernate.
This is simple DAO:
#Entity
#Table(name="attachments")
#SequenceGenerator(name="common_attachments_seq", sequenceName="common_attachments_seq", allocationSize=1)
public class AttachmentDAO implements Modifications {
private Long id;
private String name;
private Blob content;
private Date modified;
public AttachmentDAO() {}
#Id
#GeneratedValue(strategy=GenerationType.AUTO, generator="common_attachments_seq")
#Column(updatable = false, nullable = false)
public Long getId() {return this.id;}
public void setId(Long id) {this.id=id;}
#Column
public String getName() {return this.name;}
public void setName(String name) {this.name=name;}
#Column
public Blob getContent() {return this.content;}
public void setContent(Blob content) {this.content=content;}
#Column
public Date getModified() {return modified;}
public void setModified(Date date) {modified=date;}
}
This is integrator that sets modifications listener:
public class HibernateIntegrator implements Integrator {
#Override
public void integrate(Metadata metadata, SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) {
EventListenerRegistry eventListenerRegistry=serviceRegistry.getService(EventListenerRegistry.class);
ModificationsEventListener mod=new ModificationsEventListener();
eventListenerRegistry.appendListeners(EventType.UPDATE, mod);
eventListenerRegistry.appendListeners(EventType.SAVE, mod);
eventListenerRegistry.appendListeners(EventType.SAVE_UPDATE, mod);
}
#Override
public void disintegrate(SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) {
}
}
This is ModificationsEventListener which actually updates "modified" parameter:
public class ModificationsEventListener extends DefaultSaveOrUpdateEventListener {
#Override
public void onSaveOrUpdate(SaveOrUpdateEvent event) throws HibernateException {
Object o=event.getObject();
if (o instanceof Modifications) {
Date now=new Date();
Modifications doc=((Modifications)o);
doc.setModified(now);
}
super.onSaveOrUpdate(event);
}
}
This is the code that saves DAO:
// DiskFileItem currentFile = file uploaded to server - Apache's commons-fileupload-1.3.2.jar
Session hibSession=null;
Transaction tx=null;
try {
SessionFactory sf=AttachmentsSessionFactory.getSessionFactory();
hibSession=sf.openSession();
tx=hibSession.beginTransaction();
AttachmentDAO stub=new AttachmentDAO();
stub.setName(fileName);
long length=currentFile.getSize();
InputStream ins=currentFile.getInputStream(); // this is FileInputStream
LobCreator lobs=Hibernate.getLobCreator(hibSession);
Blob blob=lobs.createBlob(ins, length);
stub.setContent(blob);
hibSession.save(stub);
tx.commit();
ins.close();
currentFile.delete();
} catch (Exception ex) {
if (tx!=null) tx.rollback();
log.error("", ex);
} finally {
if (hibSession!=null&&hibSession.isOpen()) {
hibSession.close();
}
hibSession=null;
}
But this code throws error:

sql that hibernate executes is this:
Hibernate:
select
nextval ('common_attachments_seq')
Hibernate:
insert
into
sys_attachments
(content, modified, name, id)
values
(?, ?, ?, ?)
Hibernate:
update
sys_attachments
set
content=?,
modified=?,
name=?,
where
id=?
Apparently problem is that Hibernate inserts record and right after that makes update. FileInputStream doesn't like it because it's closed right after insertion.
When I disable Integrator (updating "modified" field) then it works OK.
Is there any way how to make it work?
I have just seen this:
How to autogenerate created or modified timestamp field?
And it helped me to solve my problem. I had to use EventType.PRE_UPDATE and EventType.PRE_INSERT in Integrator, instead of EventType.SAVE_UPDATE, EventType.SAVE and EventType.UPDATE. And then update values in those listeners like this:
Modifications doc=((Modifications)entity);
doc.setModified(now);
setPropertyState(state, propertyNames, "modified", now);
Where property state setter is here:
private void setPropertyState(Object[] propertyStates, String[] propertyNames, String propertyName, Object propertyState) {
for(int i=0;i<propertyNames.length;i++) {
if (propertyName.equals(propertyNames[i])) {
propertyStates[i]=propertyState;
return;
}
}
}
I have my service as;
#Path("/fileservice/")
public class FileService {
#POST
#Path("/{path}/{filename}/{source}/{client}")
public Response getFilePath(
#PathParam("path") String filePath,
#PathParam("filename") String fileName,
#PathParam("source") String fileSource,
#PathParam("client") String clientId) {
.......
}
and have an jars activator;
#ApplicationPath("rest")
public class JaxRsActivator extends Application{
}
I do not have web.xml.
When i try to access this war from the browser;
i use;
http://localhost:8080/mywar/rest/fileservice
But I'm getting;

Can anybody help me what I'm doing wrong?
You can't access that resource from a web browser because you have it set as a POST method. You'd need to use a tool that can send POST requests and provide the /{path}/{filename}/{source}/{client} parameters you have defined.
According to the JAX-RS documentation the #PathParam should be used for GET requests.
For POST requests, one should either consume JSON or JAXB, for full entity beans, or make use of the #FormParam when the intention is to retrieve information that conforms to the encoding specified by HTML forms. This answer, by #D.Shawley, may elucidate you more on this subject.
Taking the code you've posted as basis, the following is a simple working example:
The Base URI for all REST services
#ApplicationPath("/rest")
public class JaxRsActivator extends Application {}
The REST Service
#Path("/fileservice")
public class FileService {
#GET
#Path("/{id}")
#Produces("text/html")
public Response getFileId(#PathParam("id") String fileId) {
System.out.println(fileId);
return Response.ok().entity(fileId).build();
}
#POST
#Path("/file")
#Consumes(MediaType.APPLICATION_XML)
public Response createFile(MyFile myFile) {
System.out.println(myFile.id);
return Response.ok().build();
}
}
The entity
#XmlRootElement(name="file")
public class MyFile {
#XmlElement
public String id;
#XmlElement
public String name;
public MyFile() {}
}
Your WAR pom.xml file should look like this:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>war-group</groupId>
<artifactId>war-artifact</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<dependencies>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
</project>
Then, in order to test your REST service, you could create a simple client that could look like this:
public class FileServiceClient {
public static void main(String[] args) throws Exception {
callRestServiceGET();
callRestServicePOST();
}
protected static void callRestServiceGET() {
URI uri = null;
try {
uri = new URI("http://localhost:8080/war-artifact-0.0.1-SNAPSHOT/rest/fileservice/98765");
} catch (URISyntaxException e) {
e.printStackTrace();
}
Client client = ClientBuilder.newClient();
Response response = client.target(uri).request().get();
System.out.println("GET sended, response status: " + response.getStatus());
}
protected static void callRestServicePOST() {
URI uri = null;
try {
uri = new URI("http://localhost:8080/war-artifact-0.0.1-SNAPSHOT/rest/fileservice/file");
} catch (URISyntaxException e) {
e.printStackTrace();
}
Client client = ClientBuilder.newClient();
String xml = "<file><id>1234567</id><name>abc</name></file>";
Response response = client.target(uri).request().post(Entity.xml(xml));
System.out.println("POST sended, response status: " + response.getStatus());
}
}
