We know that there is a archetype of hibernate , archetype of spring , archetype of struts. how i can generae a structure of project that collect the three archetype ?
or in other wise, how to generate a structure of jee project that collect a set of frameworks ?
thx
You can just add the dependencies to a clean maven pom.xml.
<project
...
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
...
</plugin>
</plugins>
<dependencies>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.2.3</version>
</dependency>
<!-- spring hibernate etc here -->
<dependency>
</dependencies>
I would add them one at a time and carefully build up the required configuration for each pieces while making sure the project continues to compile at each step.

I need to modify and deploy some liferay modules that I didn't write. The original developer is not with the company anymore and there's almost no documentation on the code. The project is structured differently to the liferay projects I'm familiar with, so I'm struggling with the deployment.
It's a maven project with a number of modules, and when I build it generates multiple jar files. When I copy one of those jar files to my local deployment folder Liferay prints something like:
13:07:23,201 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][ModuleAutoDeployListener:70] Module for /Users/ali/LIFERAY/liferay-portal-6.2-ee-sp14/deploy/com.monator.ehp.routes.servicemix.moci-1.6.1.jar copied successfully. Deployment will start in a few seconds.
... and then nothing. If I check the liferay/data/osgi/modules/ directory I do see the jar file is present there, however when I test the behaviour I do not see my changes reflected, even after restarting the tomcat server.
We're running Liferay 6.2 ee sp14 with tomcat and postgres. I believe the modules in question are osgi modules, but I don't think that changes the deployment method?
EDIT: This is the main project pom file, running "mvn install" in the same directory does not create a war file, but does create multiple individual jar files in the various child module folders:

Liferay 6.x can deploy war files, not jars!
Maybe your maven projects builds many jars for then build a war file?
Better if you post the pom.xml and the internet crew try to understand the mistery..
EDIT:
This project build osgi jars for Apache Camel to create some custom routes! https://camel.apache.org/ , there are not Liferay modules!
(Maybe Liferay plays as Camel consumer/producer?)

While i am going to modify the code in java file or the controller those are not effecting while I am running the project. I think Maven is not compiling the Java code.
Is the folder structure is correct ?
Where the class files are generated in the project ?
Can any one suggest with explanation.
Based on your question and the comments below it I try to give you a answer:
is the folder structure correct?
Yes ist is. It follows the Maven standard directory structure described here: http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html
It however misses a webapp-folder (see next point) which will not make your build fail but end in a war not containing a WEB-INF folder - hence it is not a standard webbapplication as defined by the Java EE standard (http://docs.oracle.com/javaee/6/tutorial/doc/bnadx.html).
Where are the class files generated in the project?
After maven runned the phase compile (mvn compile) of the default lifecycle (http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html) the compiled class files will be placed under /target/classes.
If you continue to the phase package (mvn package) maven will build a war (jar is the default packaging type which was overwritten in your pom) containing your classes as well as your resources which is placed under /target
Note: If you are building a webapplication you place your website's content such as a deployment descriptor (web.xml) or HTML/JSP/JSF pages etc. under a folder src/main/webapp (the WEB-INF folder should be under src/main/webapp/WEB-INF).
Regarding the comments disscussion
If you expect to see changes in Java files on the fly Maven will not support you out of the box. Maven is a build tool - e.g. if you change something in your project you will request maven to build the project again to have the changes ready in a deployable form (e.g. you have a war file in your /target folder which you can then deploy).
If you want to see changes on the fly you should try a websearch for topics such as Hotdeployment, JRebel, embedded jetty since there are quite a few options available to archive this.
One general approach to have hotdeployment "out of the box" is to point the exploded directory of a hotdeploy-supported (web)(application) server to the exploded directory of your maven build. Right on the same level as you will find your spring-login-security-xml.war the is a folder spring-login-security-xml which contains the unpacked webapplication. This will however not spare you to have a build per change.
This is the first issue that popped up for me when my class files were not being generated. My fix does not apply to this question, but I'm mentioning it here in case it helps someone else.
I had a quick copy and paste setup with a single top level pom.xml. In it I had set
<packaging>pom</packaging>
which caused the java files to be ignored. The fix was to remove the packaging tag, letting it default to jar.
I have some dependencies in my webapp that I've marked as provided because I expect them to be provided by an appserver (maybe a production environment provides these dependencies at the specified versions). How do I simulate that when I'm running tests or in development on my localhost using for example the tomcat7-maven-plugin goals like run?
I can't see any way to do it without manually copying jars around. I can see how to use the test classpath - is there something wrong with what I'm trying to do?
OK, I've found a way of getting this to work - it's reasonable but there's a duplication of dependency information and a magic profile... I feel that the tomcat7-maven-plugin should provide a means of making provided dependencies available in the container when running.
Add a profile that is activated when the tomcat plugin runs, and add the dependencies that have provided scope with compile scope to that profile, eg.
... in project pom ...
<dependencies>
<dependency>
<groupId>com.mycompany</groupId>
<artifactId>my-provided-artifact</artifactId>
<version>1.2.3</version>
<scope>provided</scope>
</dependency>
</dependencies>
...
<profiles>
<profile>
<!-- profile activated as cli param when tomcat7 plugin runs -->
<id>tomcat</id>
<dependencies>
<dependency>
<groupId>com.mycompany</groupId>
<artifactId>my-provided-artifact</artifactId>
<version>1.2.3</version>
<scope>compile</scope>
</dependency>
</dependencies>
</profile>
</profiles>
I use, for example, this:
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<path>/myApp</path>
</configuration>
<dependencies>
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.3</version>
</dependency>
</dependencies>
</plugin>
and then also include the dependency again later with provided.
I have 2 projects that I am using the FindBugs plugin in maven to identify bugs. I am also using the #SuppressFBWarnings annotation to ignore specific bugs.
With the first project, I added the dependancies to the pom.xml and both the findbugs report and the annotation worked fine. With the second project, the report gets generated, but it still identifies bugs that I have suppressed using the annotation.
I run mvn clean install site to generate the reports on my machine in the build folder.
Each of the 2 projects I mentioned, have sub-projects with their own pom.xml files in their sub-directories, so in the parent directory, I also have a pom.xml. This directory layout is mirrored identically in both of the main projects.
Here is the XML I added to the parent poms under the <reporting> tag:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<xmlOutput>true</xmlOutput>
<findbugsXmlOutput>true</findbugsXmlOutput>
<fork>true</fork>
<threshold>Low</threshold>
<effort>Min</effort>
</configuration>
</plugin>
Also, in this same parent pom, I added this to the <dependencyManagement><dependencies> section:
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>annotations</artifactId>
<version>2.0.1</version>
</dependency>
This is identical in both of the main projects poms.
Now, in the sub-projects where I actually use the #SuppressFBWarnings annotation, and only in that particular sub-project, I have this under <dependencies>:
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>annotations</artifactId>
<version>2.0.1</version>
</dependency>
Also, this is mirrored in the other working project. I copied and pasted directly.
One project works perfect and I can successfully suppress false positives. The other project completely ignores the #SuppressFBWarnings anotation, and I can't seem to fix it.
Is there something I'm missing here?
I think that if an annotation is not found, instead of giving an error, it will just ignore it? How can I tell if its not found?
Hopefully this is a simple fix.
Thanks.
#SuppressFBWarnings was introduced with the annotation in version 3. That's why it should look like this:
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>annotations</artifactId>
<version>3.0.1</version>
</dependency>
Try to add annotations artifcat to the plugin dependencies :
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<xmlOutput>true</xmlOutput>
<findbugsXmlOutput>true</findbugsXmlOutput>
<fork>true</fork>
<threshold>Low</threshold>
<effort>Min</effort>
</configuration>
<dependencies>
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>annotations</artifactId>
<version>2.0.1</version>
</dependency>
</dependencies>
</plugin>
Ensure that the dependency added is in between the dependencies tags.
Like this:
<dependencies>
<dependency>
<groupId>something</groupId>
<artifactId>something</artifactId>
<version>something</version>
</dependency>
<dependencies>
We are using maven to build an EAR that contains WAR, the JARS are duplicated on both EAR's root and WAR's lib folder, I read about the skinny jars to remove the jars from the WAR but I don't want this as I want to keep the WAR as stand alone unit,
IS there a way to do it the other way around and remove the JARs from the EAR's root folder ?
attached is the EAR POM
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-ear-plugin</artifactId>
<version>2.6</version>
<configuration>
<modules>
<webModule>
<groupId>com.csv.xyz</groupId>
<artifactId>web</artifactId>
</webModule>
</modules>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>com.csv.xyz</groupId>
<artifactId>web</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>war</type>
<scope>compile</scope>
</dependency>
</dependencies>
The "maven-skinny-war" solution isn't any drawback in your case. Also have a look at this question and my answer: How to make maven place all jars common to wars inside the same EAR to EAR root?
With this solution you will first get WARs packaged with their own dependencies and second, an EAR module with skinny WARs. So everything is deployable on its own and nothing is duplicated.
I don't think this would be a good idea because of the class loader architecture. If a JAR is part of a WAR, it's defined by the web app class loader, which may result in multiple instances. If it's part of an EAR, it's defined by the enterprise app class loader, which is a different class loader.
To remove a dependency from the EAR lib folder, declare the dependencies as provided in the EAR pom, for example to remove commons-lang:
<dependencies>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
<scope>provided</scope>
</dependency>
</dependencies>
Just make sure if you have EJB modules that they don't require the dependency! Also webModules do not contribute to the EAR's root lib folder, do you have more dependencies in you ear pom?
