I'm trying to store portlet preferences in a backing bean (JSF) as mentioned in this tutorial
But, I can not understand how they imported Preference class here
Map<String, Preference> mutablePreferenceMap =
(Map<String, Preference>) elResolver.getValue(
facesContext.getELContext(), null, elExpression);
the package javax.portlet.* don't contain faces.preference.Preference
Anyone has an idea about that, specially how to save portlet preferences
thanks in advance
You have to add the Liferay Faces Bridge JAR to your project.
Add the following dependencies:
<dependencies>
<dependency>
<groupId>com.liferay.faces</groupId>
<artifactId>liferay-faces-alloy</artifactId>
<version>3.1.0-ga1</version>
</dependency>
<dependency>
<groupId>com.liferay.faces</groupId>
<artifactId>liferay-faces-bridge-impl</artifactId>
<version>3.1.0-ga1</version>
</dependency>
<dependency>
<groupId>com.liferay.faces</groupId>
<artifactId>liferay-faces-portal</artifactId>
<version>3.1.0-ga1</version>
</dependency>
</dependencies>
and the liferay-faces-bridge-api jar which is a dependency for liferay-faces-bridge-impl has this Preference interface.

I know we can use this #ApiModelProperty annotation from this link to hide an id from the request when we use Swagger-Ui
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
But I am using this spring doc OpenApi dependency
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.2.32</version>
</dependency>
I am not getting this annotation #ApiModelProperty when I used springdoc-openapi-ui. What could be the annotation for this?
You have to replace swagger 2 annotations with swagger 3 annotations (it is already included with springdoc-openapi-ui dependency). Package for swagger 3 annotations is io.swagger.v3.oas.annotations.
It's all explained here:
https://springdoc.org/migrating-from-springfox.html
I began to study Vaadin and wrote the code as stated in the tutorial:
List<PatientEntity> personList = new ArrayList<>();
Grid<PatientEntity> grid = new Grid<>(PatientEntity.class);
I got errors in the second line
Type 'com.vaadin.ui.Grid' does not have type parameters" () and "Diamond operator is not applicable for non-parametrized types" (<>)
Dependencies from pom.xml:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-bom</artifactId>
<version>13.0.11</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-core</artifactId>
</dependency>
</dependencies>
</dependencyManagement>
Type 'com.vaadin.ui.Grid' does not have type parameters
This is not the correct package. I think this is the grid from Vaadin 8. Try com.vaadin.flow.component.grid.Grid
Edit: adding #Tazavoo's comment into my answer, as it might very well solve your problem.
Have you added a Vaadin dependency to your pom.xml? Adding it to <dependencyManagement> does not actually add it as a dependency. You should keep the vaadin-bom there, as it will control the versions, but move vaadin-core to your actual <dependencies> tag.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-bom</artifactId>
<version>13.0.11</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-core</artifactId>
</dependency>
</dependencies>
With this pom structure your IDE should automatically suggest the correct Grid import to you (after you remove the incorrect import statement of course)
I'm not sure but you should try to remove the PatientEntity.class from the constructor
(as in the second exemple of vaadin)
After logging in on website using Okta for authentication I go to the home page and it gives a null pointer exception when I am trying to grab the logged in User Principal.
Here is my Security Dependencies: (I am using Spring boot 1.5.6)
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>com.okta.spring</groupId>
<artifactId>okta-spring-boot-starter</artifactId>
<version>0.2.0</version>
</dependency>
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.2.0.RELEASE</version>
</dependency>
Here is my controller:
#GetMapping("/")
public String home(Model model, Principal principal) {
System.out.println(principal.getName());
return "/home";
}
Any help to point me in the right direction would be great. I have looked at the documentation and it seems I am not doing things incorrectly.
Actually i am facing a problem that Swagger-ui can't show me input for MediaType.APPLICATION_OCTET_STREAM, so lets imagine this next service:
#PUT
#Path("/performAudioQuery")
#Consumes(MediaType.APPLICATION_OCTET_STREAM)
public Response performAudioQuery(InputStream audioInputStream){
//Impl of the service
}
and here are the dependencies
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-jersey2-jaxrs</artifactId>
<version>1.5.6</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.22.2</version>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
and i am using wildfly 9.x
So what should i do to make it possible for Swagger-ui working good with this previous service?
The current version of the Swagger/OpenAPI specification (2.0) doesn't deal kindly with file uploads as what's known as body parameter. We've formulated a workable solution that is covered at https://github.com/OAI/OpenAPI-Specification/issues/50 - however that solution is currently not fully supported by swagger-core and not supported at all in swagger-ui.
This question already has answers here:
Display dynamic image from database or remote source with p:graphicImage and StreamedContent
(4 answers)
Closed 7 years ago.
I have JSF:
<p:graphicImage value="#{chatView.userPhoto}">
<f:param name="userId" value="#{user.id}"/>
</p:graphicImage>
user.id is valid I have checked.
And bean:
#ManagedBean
#ViewScoped
public class ChatView extends BaseView {
/*
* Injecting managed beans in each other
* http://balusc.blogspot.com/2011/09/communication-in-jsf-20.html#InjectingManagedBeansInEachOther
*/
#ManagedProperty("#{chatUsers}")
private ChatUsers users;
public StreamedContent getUserPhoto() {
// there output is {}
System.out.println(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap());
return new DefaultStreamedContent();
}
}
But I have empty map in debug output for requestParameterMap. Any idea why?

But anyway I get empty request parameter map in debug output.
Thank to this answer https://stackoverflow.com/a/25425111/836701 I found the solution. The problem was in #ViewScope it should be #SessionScope for getting parameters from f:param.
