Issue with @ManagedBean injection with LIferay 6.2 Faces + Primefaces

[7年前 に Tulsi Rai によって更新されました。]

Hello,
We are trying to build a new liferay 6.2 project with JSF/Primefaces frontend technology. I ran into issue with accessing the managed bean from the xhtml. Here's what we are using -

• liferay-plugins-sdk-6.2
• liferay-portal-6.2-ce-ga6
• java 7.*
• Liferay IDE

The issue is that I don't have access to the managed bean named as "simple" in my view.xhtml as the #{simple.greeting} call would not return any thing and nothing happens while clicking on Submit and Cancel buttons. In fact, the @PostConstruct init() method does not seem to have invoked at all as I don't see the message being printed in the console.

Can someone please give me some idea as to what going on here?
Thank you.
Tulsi

Here are my program files -
SimpleBean.java

package com.lifery.jsf.beans;

import java.awt.event.ActionEvent;

import javax.annotation.ManagedBean;
import javax.annotation.PostConstruct;
import javax.faces.bean.ViewScoped;

@ManagedBean(value="simple")
@ViewScoped
public class SimpleBacking {
	
	private String message;
	private String name;
	 
	
	@PostConstruct
	public void init(){
		System.out.println("Initializing...");
		message = "Welcome to Liferay JSF!";
	}
	
	public String greeting(){		
		return message;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
	public void processAction(ActionEvent actionEvent){
		System.out.println("Processing with - " + name);
	}

	
	public void cancelAction(ActionEvent actionEvent){
		System.out.println("Cancelling...");
	}

}

Hello Tulsi,

You should be able to try our primefaces demo from here:
https://web.liferay.com/community/liferay-projects/liferay-faces/demos#primefaces-applicant-portlet

The source code for the demo will show you how to access something in your bean like this:
https://github.com/liferay/liferay-faces-bridge-impl/blob/4.x/demo/primefaces-applicant-portlet/src/main/webapp/WEB-INF/views/applicant.xhtml#L20

you can also use this archetype in order to quickly create a primefaces portlet to start a new JSF project that has the correct jars you will need:

mvn archetype:generate \
  -DarchetypeGroupId=com.liferay.faces.archetype \
  -DarchetypeArtifactId=com.liferay.faces.archetype.primefaces.portlet \
  -DarchetypeVersion=3.0.1 \
  -DgroupId=com.mycompany \
  -DartifactId=com.mycompany.my.primefaces.portlet

For an example of PostConstruct, you can try the export pdf demo.

Let us know if those examples work in your environment. If there are any error messages, please let us know what they are.

Hope that helps!

Phil

Thanks Philip.

I finally got it working.
I still have one question - since its an Ant based project, the Liferay IDE produces ivy.xml with the older version of jars as shown below, is it possible to override those older version to the current version? How can I do so?

How can I upgrade the primefaces from 3.5 to 6.0?

<dependency name="org.primefaces.primefaces" org="com.liferay" rev="3.5" />

Hi again Tulsi,

Thank you for letting us know that you are using Ivy. Unfortunately, our archetypes and version scheme are not released with an ivy.xml. So, what you will need to do is use the archetype portlet at liferayfaces.org or generate a maven archetype using this command:

$ mvn archetype:generate \
  -DarchetypeGroupId=com.liferay.faces.archetype \
  -DarchetypeArtifactId=com.liferay.faces.archetype.primefaces.portlet \
  -DarchetypeVersion=3.0.1 \
  -DgroupId=com.mycompany \
  -DartifactId=com.mycompany.my.primefaces.portlet

The Primefaces 6 jar will be automatically included by that command as well as all of the correct groupIds, artifactIds, and versions (GAVs) for the bridge jars that you need to start using with liferay 6.2. Then, you will need to manually edit your ivy.xml file to use those GAVs from either the pom.xml or the build.gradle files generated by mvn. It looks like you will need these GAVs for what you are trying to do:

dependencies {
    compile group: 'org.primefaces', name: 'primefaces', version:'6.0'
    compile group: 'commons-fileupload', name: 'commons-fileupload', version:'1.3.1'
    compile group: 'commons-io', name: 'commons-io', version:'2.4'
    compile group: 'com.liferay.faces', name: 'com.liferay.faces.bridge.ext', version:'3.0.0'
    compile group: 'com.liferay.faces', name: 'com.liferay.faces.bridge.impl', version:'4.0.0'
    compile group: 'log4j', name: 'log4j', version:'1.2.14'
    runtime group: 'org.glassfish', name: 'javax.faces', version:'2.2.13'
    providedCompile group: 'javax.faces', name: 'javax.faces-api', version:'2.2'
}

Hope that helps!

Phil, Thanks for your guidance. I sill have an issue updating the library versions. I started a new thread specially focusing on this particular issue -
https://web.liferay.com/community/forums/-/message_boards/message/85243095

Hope you can guide me.

Thank you.

Tulsi,

Thank you for trying our suggestions and telling us step-by-step how you arrived at the current issue that you are having now. You are SO close! All you have to do now is go into your 6.2 version of liferay's webapps directory and remove your older (non-working) deployed portlet (then re-deploy).

to be more clear, you only needed to do the following steps:

cd ${LIFERAY_6.2_HOME}/tomcat/webapps
rm ${old_primefaces_portlet}
cp ${new_primefaces_portlet} ${LIFERAY_6.2_HOME}/deploy/.

Let us know if this solved your issue!

Phil

First off, THANK YOU Phil for guiding me with so many responses to resolve my issue.
Thank You

I accomplished my project goal - set up a project based on Liferay 6.2 + Primefaces 6 (the latest version).
Now my ivy looks like this -

<!--?xml version="1.0"?-->

<ivy-module version="2.0" xmlns:m2="http://ant.apache.org/ivy/maven" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nonamespaceschemalocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
	<info module="portlet_primefaces_tmpl" organisation="com.liferay">
		<extends extendType="configurations,description,info" location="../../ivy.xml" module="com.liferay.sdk" organisation="com.liferay" revision="latest.integration" />
	</info>

	<dependencies defaultconf="default">
		<dependency org="log4j" name="log4j" rev="1.2.14" />
		<dependency org="commons-fileupload" name="commons-fileupload" rev="1.3.1" />
		<dependency org="commons-io" name="commons-io" rev="2.4" />
		<dependency org="org.glassfish" name="javax.faces" rev="2.2.13" />
		<dependency org="javax.faces" name="javax.faces-api" rev="2.2" />
		<dependency org="com.liferay.faces" name="com.liferay.faces.bridge.ext" rev="3.0.0" />
		<dependency org="com.liferay.faces" name="com.liferay.faces.bridge.impl" rev="4.0.0" />
		<dependency org="com.liferay.faces" name="com.liferay.faces.bridge.api" rev="4.0.0" />
		<dependency org="org.primefaces" name="primefaces" rev="6.0" />
		<dependency org="com.microsoft.sqlserver" name="sqljdbc4" rev="4.0" /> 		
	</dependencies>
</ivy-module>

With the ivy.xml udpate, and deleting the previously deployed jar, I had one more issue as shown below -

Compiling 2 source files to C:\apps\liferay-plugins-sdk-6.2\portlets\payroll-portlet\docroot\WEB-INF\service-classes
    [javac] Annotation processing got disabled, since it requires a 1.6 compliant JVM

    [javac] 	/**

    [javac] 	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    [javac] The type java.util.Comparator cannot be resolved. It is indirectly referenced from required .class files

So I had to have the Jdk 1.6.x and the above issue was resolved!
Then I had the following issue -

Caused by: com.sun.faces.config.ConfigurationException: It appears the JSP version of the container is older than 2.1 and unable to locate the EL RI expression factory, com.sun.el.ExpressionFactoryImpl.  If not using JSP or the EL RI, make sure the context initialization parameter, com.sun.faces.expressionFactory, is properly set.
	at com.sun.faces.config.ConfigureListener.registerELResolverAndListenerWithJsp(ConfigureListener.java:694)
	at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:243)
	... 13 more

So I had to update the web.xml from version 2.5 to version 3.0. I replaced the

<!--?xml version="1.0"?-->

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	.  .  .
</web-app>

to

<!--?xml version="1.0" encoding="UTF-8"?-->
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
     .  .  . 
</web-app>

Now All is good The liferay portlet project is running with the following -

• Liferay 6.2
• JDK 1.6.0_45
• Primefaces 6.0

Now I have a completetly different issue which I think I should post it in a new thread.
As you know the project is up and running with the default database that Liferay needs. But I would like to configure to use a different database for housing the project specific tables. And as you can guess, I did find a few links but ran into an issue implementing it. So I will post it into a new thread with its own topic. Hope you will find sometime to give me a pointer or two.

Thank you again.
