11. JSF.. What about Java 9?

This post NEEDS has been UPDATED !!!


Java 9 is a bit more complicated to install than java 8, and needs Eclipse Oxygen v2 or higher. But take into account that it is adviseable to install Eclipse after installing Java 9!!!

1. Installing Java 1.9

Lets follow the steps of Shahrukh Aslam.

#download repository
sudo add-apt-repository ppa:webupd8team/java

#update reposotory
sudo apt-get update

#install
sudo apt install oracle-java9-installer

#make this java version default
sudo apt install oracle-java9-set-default

To see all the java versions installed try:

sudo update-alternatives --config java


    To verify the java version, from a terminal try java -version . If you don't get java 9, you should add the following lines to the /home/your-user-name/.bashsr file.  

    export JAVA_HOME=/usr/lib/jvm/java-9-oracle
export PATH=$JAVA_HOME/bin:$PATH

2. Install eclipse Oxygen 2

And install again Lombok.

Eclipse Oxygen2 should be installed after Java 9 installation, not before !!!

3. Update your maven pom.xml

Java 9 does not include many libraries in its JDK, so they must be included in then pom.xml file.

This matter is explained later in this post. It is commented in the pom.xml all the additional libraries needed:

4. Alternative maven pom.xml (not recommended)


This is the pom-xml that I initialy proposed. But I think the previous one is best. So take care if you use this one. We have explicitly indicated to use maven 3.7.0 compiler for Java 9 and updated the pluggins to newer versions.

The major changes are:

  • Lines 13 and 14:  Java version has changed for 1.8 to 9
  • Lines 275 and downwards: References to new pluggins are introduced. Special mention to compiler version to 3.7.0 (line 280)

5. Java Build Path aims at JDK 9 instead of JDK 5

Right Click on your project- Build Path - Configure Build Path and verify that in Java Compiler you jave JavaSE-9 in use compliance from execution environment.



In the same window, configure also Project Facets so that aims to Java 9


6. The JEP 320 or the missing reference problem

As indicates this JEP 320 all the modules that can be qualified as JEE have been deprecated. The recommended way to use them seems to be adding the jars to the build path.

PROBLEM:

The removed references/utilities from JDK 9  textually quoting are:
  • java.xml.ws (JAX-WS, plus the related technologies SAAJ and Web Services Metadata)
  • java.xml.bind (JAXB)
  • java.activation (JAF)
  • java.xml.ws.annotation (Common Annotations)
  • java.corba (CORBA)
  • java.transaction (JTA)
Related modules in Java SE 9 are also deprecated for removal:
  • java.se.ee (Aggregator module for the six modules above)
  • jdk.xml.ws (Tools for JAX-WS)
  • jdk.xml.bind (Tools for JAXB)
  This JEP will remove the nine modules listed above:
  • Their source code will be deleted from the OpenJDK repository.
  • Their classes will not exist in the JDK runtime image.
  • Their tools will no longer be available:
    • wsgen and wsimport (from jdk.xml.ws)
    • schemagen and xjc (from jdk.xml.bind)
    • idlj, orbd, servertool, and tnamesrv (from java.corba)
  • The JNDI CosNaming provider (from java.corba) will no longer be available.
  • No command line flag will be capable of enabling them, as --add-modulesdoes on JDK 9.
The rmic compiler will be updated to remove the -idl and -iiop options. Consequently, rmic will no longer be able to generate IDL or IIOP stubs and tie classes.
The JDK documentation and man pages will be updated to remove any references to these modules and tools, and to indicate the rmic changes.

Also continues with the

SOLUTION PROPOSAL:

This proposal assumes that developers who wish to compile or run applications on the latest JDK can find and deploy alternate versions of the Java EE technologies. The Reference Implementations (RIs) of JAX-WS and JAXB are a good starting point because they are complete replacements for the java.xml.ws and java.xml.bindmodules in JDK 9. The RIs are available as Maven artifacts: (note that they must be deployed on the class path)
The tools for JAX-WS and JAXB are also available as Maven artifacts:
There are also Maven artifacts that contain just the APIs of the Java EE technologies:

BUT:

Take into account that some of the references should be added <type>pom</type> that they could be found. For instance

    <properties>
       <jax.version>2.3.0</jax.version>
    </properties>

    <dependency>
      <groupId>com.sun.xml.ws</groupId>
      <artifactId>jaxws-ri</artifactId>
      <version>${jax.version}</version>
      <type>pom</type>
    </dependency>
    
    <dependency>
      <groupId>com.sun.xml.bind</groupId>
      <artifactId>jaxb-ri</artifactId>
      <version>${jax.version}</version>
      <type>pom</type>
    </dependency>
    
    <dependency>
      <groupId>javax.transaction</groupId>
      <artifactId>javax.transaction-api</artifactId>
      <version>1.2</version>
    </dependency>
    
     <dependency>
      <groupId>javax.annotation</groupId>
      <artifactId>javax.annotation-api</artifactId>
      <version>1.2</version>
    </dependency>

 But with jars that reference to APIs, we may need implementation, so for javax-activation, we may need this pom entry:

     <dependency>
      <groupId>com.sun.activation</groupId>
      <artifactId>javax.activation</artifactId>
      <version>1.2.0</version>
    </dependency>

Take into account that the pom.xml proposed at first includes this points yet.

10. JSF How to access my resources files?

Sometimes it is really difficult to access any resources form different Java applications. So let's see some scenarios: 1. Executable jar application in a NO WEB environment. Take into account that this is not a JSF application !!! It is desired to have a property file outside the "jar file" so that we can change properties when needed. For instance, we will place the properties file in the same folder that the "jar file" lies. To access the folder where the jar is, the trick is to access the folder where the compiled classed are placed and scale 3 folders . (Oh! rather strange, if anybody knows a better idea.., he will be welcome). Here is a simple code. The name of the class containing the code is ThisClass, and we have created a Property class that feeds with a file in the same folder that the" jar file" 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 /** * Gets the folder where resides the executable

The pom.xml file Eclipse complains about the simple generated file. It seems that a web.xml is required if the packaging is selected to war. The simple generated file is  1 2 3 4 5 6 7 8 9 <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> org.ximodante

9. JSF: Solving common problems

1. Target Unreachable, identifier [bean] resolved to null When you reference a bean in a xhtml file with "#{bean.method}" and get this error, you should verify that: The bean implements Serializable . The references (javax.servlet-api.4.0.0, javax.faces.2.3.3,  javax.el.api.3.0.1, org.primefaces.6.1) have been selected in your pom.xml You have created the files bean.xml and faces-config.xml in the webapp/WEB-INF folder You have used the correct annotations from CDI  (javax.inject.Named and javax.enterprise.context.SessionScoped, ...) and not ManagedBean or jsf2.2 scopes. 2. Bean declaring a passivating scope must be passivation capable This error causes server not starting and fills up the console with long chained exceptions. It is very annoying. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 SEVERE: A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start co
