Migration from Tomcat 7 to Tomcat 8

Migration from Tomcat 7 to Tomcat 8 - java

Hi I was having a maven ee project with eclipse Juno and Tomcat 7. Everything was working fine and then I moved towards up-gradation of tomcat server to tomcat 8.
Now I had to download eclipse luna so i did that and configured tomcat 8 with my project in eclipse luna. But I am getting four messages in marker.
Cannot change version of project facet Dynamic Web Module to 3.0.

Plus:
I searched a lot and messed up my web.xml and pom.xml and ./settings files as well and now I dont even remember which changes I have made but one thing i remember is that I was using servlet 2.5 in juno.
Any help in right direction would be very appreciative.
UPDATE 1:
Changed servlet to 3.0.1. But still getting same error
This facet.core.xml file of ./settings folder.
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="wst.jsdt.web"/>
<installed facet="java" version="1.5"/>
<installed facet="jst.web" version="2.3"/>
<installed facet="wst.jsdt.web" version="1.0"/>
<installed facet="jst.jaxrs" version="1.1"/>
<installed facet="jboss.m2" version="1.0"/>
</faceted-project>
When i change jst.web to 3.0 then i get error again cannot change project facet web dynamic version to 3.0

Here:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
It should be 3.0 at least since your web.xml specifies version="3.0". But maintaining this dependency may give you conflicts with Java EE 7.0 dependency here:
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
Looks like you're just copying/pasting/crossing your fingers and hoping that everything works. This is not how you're supposed to do it. Just import the relevant dependencies you will use.

Just Solved the errors by adding this to pom.xml
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>1.7</source>
<target>1.7</target>

</plugin>
</plugins>
</build>

Any help appreciated!
I had this working a day ago, I get the feeling that it's a maven problem but I'm not sure how to fix it.
Running Maven gives a build error :
No compiler is provided in this environment. Perhaps you are running
on a JRE rather than a JDK?

Try to compile it on the shell and check the mentioned paths in Eclipse:
You should have mvn and javac in your %PATH%. Additionally you can set your JAVA_HOME for example to C:\Program Files\Java\jdk1.8.0_144
Good screenshots of the Eclipse and Windows settings are already shown here

If you are building in Eclipse then make sure you are using a JDK to build and not a JRE.
Goto: Window -> Preferences -> Java -> Installed JREs
Then: Verify you are using a JDK and not a JRE.

Maven not building with server's servlet-api

Scenario
I am trying to add server's servlet-api into my existing Dynamic Web Application after reading BalusC's answer on this post.
So from start in am using maven dependency for my project
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>${servlet.version}</version>
<scope>provided</scope>
</dependency>
After reading the BalusC's answer I removed the javax.servlet dependency from pom.xml and I added *Target Runtime into my project.
*
Problem
After this all the errors (in eclipse's window) have gone. But when I try to maven clean install it gives [ERROR] COMPILATION ERROR : package javax.servlet does not exist.
But again if I added the javax.servlet's dependency in pom.xml then it works fine.

P.S: I am using Java 8, Apache tomcat 8 and maven 3.

It's quite correct in stating it can't find the class as you don't have it in your pom file...
Having the dependency there as "provided" is correct. At compile time it'll use stubs downloaded from a repository, at runtime it will use the actual classes installed into and provided by the servlet container.
Balus's answer isn't relevant to maven projects, only native Eclipse projects that aren't built externally to Eclipse.

#Junaid, I had the same problem at my workplace. Later I realized that servlet-api.jar file was not the repository provided by workplace. I guess, we are behind the proxy and that downloads the file from local repository than maven. I had to use the j2ee.jar file for the purpose.

I have added dependency in Pom.xml but Maven is not picking up, maven build gets fails

I need to use gson jar for saving a POJO file to java.For this I added its dependency in Pom.xml
I have this jar in my local m2 repository
But in import statement I am getting this error
I did update project and clean project but didn't resolved the issue.
I then added this jar through add external jar
With this the compilation error got resolved
But when I do Maven install and Maven build it gets failed, the error I am getting is:
It is giving error on import statement, for Gson.

Can anyone please suggest what I am missing or how should i resolve this error

You got wrong dependency declared. It should be
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.7</version>
</dependency>
while your groupId is <groupId>com.google.code.gson.gson</groupId> - notice double .gson at the end.
UPDATE:
So as you have pasted your POM now we can see what is the problem.
You have given dependency (gson) in Dependency Managemet not in Dependencies. You have to include it in Dependencies as well. To understand what dependency management is, read mavens doc https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html

In the project explorer it is shown that project is running on java 1.5
So i changed it to java 1.8 from java build path of project
i removed the java 1.5 and pointed it to java 1.8
then the changes were visible.
but when i update the pom.xml it again show java 1.5.
Also in the project facets it is java 1.8
Please help me in making it java 1.8

Sparsh , In the plugins options of maven you should add the compiler level
org.apache.maven.plugins
maven-compiler-plugin
2.3.2
<configuration>
<source>${jdk.version}</source>
<target>${jdk.version}</target>
</configuration>
</plugin>
<plugins>
And in your properties stanza , you should have
<properties>
<jdk.version>1.8</jdk.version>
</properties>

How to run Spring 3.2 project in Tomcat V6.0.45

I need to develop a spring project. Requirements are as follows:
Spring - 3.0
Hibernate - 3.0
MySql 5.5
Tomcat 6.0
JDK 1.7
I am not using web.xml instead I am using java configuration.When I am trying to run my project on Tomcat v6.0 (by right click in eclipse on project -> Run at Server) it is saying that this project can not be run on any server. I have no idea how to run this project.
My pom.xml is as follows :
<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">

My Facets setting is as follow :-
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="wst.jsdt.web"/>
<installed facet="wst.jsdt.web" version="1.0"/>
<installed facet="java" version="1.7"/>
<installed facet="jst.web" version="3.1"/>
</faceted-project>
I searched some articles and tried to change jst.web to 2.4 instead of 3.1 but it is not working. If I am trying to edit Project Facets through eclipse it is giving me error as Can not change version of project facet dynamic web module to 2.5. Kindly suggest me how to run this project?

Java based configuration for the web (using a ServletContainerInitializer which in turn for Spring will use a WebApplicationInitializer) is a Servlet 3.0 feature. Tomcat 6 supports the Servlet 2.5 specification and as such will not support java based configuration. In short when using Tomcat 6 you MUST use a web.xml. See this for information on which servlet specification is supported by which Tomcat version.
To fix either upgrade to Tomcat 7 or use a web.xml.

Just Solved the errors by adding this to pom.xml <build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.0.2</version> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> </plugins> </build>
