Ive been using anotation for my beans (I havent used them before) and I found out I have to include some dependencies and so on, like this:
<!--JSF API-->
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.0.2</version>
</dependency>
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.0.2</version>
</dependency>
<!-- PrimeFaces -->
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>3.3</version>
</dependency>
<!-- JSF -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.1.2</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>
<!-- Javax Servlet. This needs to be included for runtime only! -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
and well.. the problem is that the I keep getting the error of
The import javax.faces cannot be resolved
Every time I need to use the managed bean... I am using Maven and I am supposed to have downloaded all things I need, I also tried other POM and in that project I can use anotations, so, I guess is a misconfiguratino of the POM? I didnt do anything special to ecplise, except enable the maven clean, maven eclipse, and maven eclipse skip test
I really checked other answers, like these:
The import javax.servlet can't be resolved
How do I import the javax.servlet API in my Eclipse project?
but nothing, any idea what could be wrong??
You should not import the servlet API but implementation of the API, for example the servlet container implementation you want on which you want to run your project : Tomcat, JBoss, Websphere, Glassfish....
E.g. for tomcat :
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-servlet-api</artifactId>
<version>7.0.30</version>
<scope>provided</scope>
</dependency>
Thanks for the answer, I checked that using Maven its a little bit different and in the built path you have to specify the path for your maven repository, so, it will incluide all libraries directly or you can copy and past them into your project

I'm new to Maven and not sure how to write dependancies for my pom.xml
I am trying to use the following class:
import org.apache.activemq.junit.EmbeddedActiveMQBroker;
And this is my attempt at writing a dependancy:
<dependency>
<groupId>org.apache</groupId>
<artifactId>activemq-junit</artifactId>
<version>5.15.9</version>
</dependency>
But I am still getting an error
Try with the following.
<dependency>
<groupId>org.apache.activemq.tooling</groupId>
<artifactId>activemq-junit</artifactId>
<version>5.13.1</version>
<scope>test</scope>
</dependency>
You can get the details from mvnrepository.com.
First of all we go to the official Maven Dependencies Page of ActiveMQ - https://mvnrepository.com/artifact/org.apache.activemq/activemq-broker/5.15.9.
Then, we go to the "Test Dependencies" category, where we clearly can see the JUnit artifact.
so, use in your pom.xml file next dependency for version 5.15.19:
<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-broker -->
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-broker</artifactId>
<version>5.15.9</version>
</dependency>
UPDATE
Add also the next dependency:
<!-- https://mvnrepository.com/artifact/org.apache.activemq.tooling/activemq-junit -->
<dependency>
<groupId>org.apache.activemq.tooling</groupId>
<artifactId>activemq-junit</artifactId>
<version>5.15.9</version>
<scope>test</scope>
</dependency>
I'm using the following Maven dependency for the auth0 jwt library for Java:
<!-- https://mvnrepository.com/artifact/com.auth0/java-jwt -->
<dependency>
<groupId>com.auth0</groupId>
<artifactId>java-jwt</artifactId>
<version>3.8.1</version>
</dependency>
When I try to import the package in a Java servlet like this:
com.auth0.jwt
the auth0 isn't recognised, and I get the message Cannot resolve symbole 'auth0'
I've tried different versions of the dependency, and also cleaning and rebuilding the project, and closing and opening IntelliJ, but it still isn't recognised.
I've also looked at the auth0 Java quickstart, which suggests that for a Java servlet I may need to use these Maven dependencies:
<dependency>
<groupId>com.auth0</groupId>
<artifactId>mvc-auth-commons</artifactId>
<version>1.+</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>
I'm already using the 2nd one (for the servlet-api). The com.auth0 dependency isn't recognised at all though, as a valid dependency.
What can I try in order to import com.auth0.jwt?
I tried the same dependency in a Google Cloud Endpoints project:
<!-- https://mvnrepository.com/artifact/com.auth0/java-jwt -->
<dependency>
<groupId>com.auth0</groupId>
<artifactId>java-jwt</artifactId>
<version>3.8.1</version>
</dependency>
I could then import com.auth.jwt. I'm guessing that the library only works inside an Endpoints API.
Trying to start an Eclise Maven Web-Project in J2EE preview server (in Glassfish4, it works fine) i get an error:
java.lang.ClassNotFoundException: javax.faces.webapp.FacesServlet
Howewer, trying to make the fix like adviced on some another topik in this forum:
set in properties->project->fasets-> user library the jsf-api-2.1,jar
(as external jar, what is not nice),
i get another error :
Started ServerConnector#1727e0ec{HTTP/1.1,[http/1.1]}{0.0.0.0:8080}
java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/faces/webapp/FacesServlet
Searching for solution i found the info, that this is caused by classes in
javaee-web-api what are just blueprints and server must have implementaion for them.
That is why for example you write maven dependency for that as provided, like:
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
So i guess it is in this external jar too, it just not suppose to be included. What jar must i add then to fix this problem, or there is another better solution for this?
you can add below dependency into project pom.xml
and try to update the project.'
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.1.7</version>
</dependency>
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.1.7</version>
</dependency>
or you can also add
<dependency>
<groupId>javax.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>
I have maven-depenencies folder which lists over 50+ jars I need for compile and testing on my local. In addition POM.xml have specific (see snippet) which lists the dependencies I wanted in "target/final_build.jar". I do not want rest of maven - dependencies I can see on eclipse IE. I just want following packaged as aprt of final jar..
What is the easy way to accomplish . I tried copy-dependencies but it copied all Maven dependencies and not the 4 listed in pom.xml. More over they are copied over to lib/src folder.
Desired state is to just have 4 dependencies mentioned below are part of "target/outputfile.jar"
<dependencies>
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-core</artifactId>
<version>3.0.3</version>
</dependency>
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-stream</artifactId>
<version>3.0.3</version>
</dependency>
</dependencies>
Dependencies that are needed for compile/test but not for the application (because the (EE-/JDK-/?-) Container already have this classes) can be specified by the dependency scope provided:
<dependencies>
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-core</artifactId>
<version>3.0.3</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-stream</artifactId>
<version>3.0.3</version>
<scope>provided</scope>
</dependency>

I have a standard J2EE web application that includes web services. I'm using the webservices-rt library to host the services. [See the maven dependency below]. However, I get the following exception at run time:

Maven WS Dependency
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>webservices-rt</artifactId>
<version>1.4</version>
<scope>compile</scope>
</dependency>
Am I missing a library? I've tried adding jaxws-rt. However, that requires an additional repo [jboss]. I'm a bit leery of that, as that it introduces a lot of new libraries into the project.
If you are using Maven, add below to your project should solve your problem:
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-rt</artifactId>
<version>2.3.2</version>
</dependency>
You don't have to add others jar because it will automatically pull the rest of dependencies. I prefer to add the jar to my war instead of Tomcat lib. I think it is more portable.
try
The JAX-WS dependency library “jaxws-rt.jar” is missing.
Go here http://jax-ws.java.net/.
Download JAX-WS RI distribution.
Unzip it and copy “jaxws-rt.jar” to Tomcat library folder “{$TOMCAT}/lib“.
Restart Tomcat.
For a maven, tomcat application try these dependencies in your pom.xml
<dependencies>
<!-- jax-ws maven dependency -->
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-rt</artifactId>
<version>2.2.8</version>

I hope this works for new people who will face this issue

Declaring the JBoss repo doesn't automatically import the repo libraries. It simply makes the libraries available for importing.
Bottom line is that if you want to use a class that's in a library, then you have to pull the library into your project. If the library is in the JBoss repo, then you have to declare the JBoss repo.
