#cyperweb
Try http://cyperweb.ng.bluemix.net to see what this app looks like,
you can fork this project @github
or @oschina.
###Technique stacks
To name but a few:
- Spring MVC
- Spring JDBC + OpenJPA
- Spring Cloud
- Maven
- Websphere Liberty Profile 8.5.5 or Tomcat 7
- MySQL
###How to deploy the app to Bluemix.
You can either install cloud foundry plugin from
Eclipse marketplace, or you can use cloud foundry CLI like this:
$cf login -a https://api.ng.bluemix.net
API endpoint: https://api.ng.bluemix.net
Username> your username
Password> your password
$cf create-service mysql 100 mysql-cyper
$cf services
$cf bind-service cyperweb mysql-cyper
$cf push cyperweb --no-manifest --no-start -p ./cyperweb.war
$cf start cyperweb
###Maven You can use below command to generate a war package for bluemix.
mvn clean packagethe generated file will be cyperweb.war for this project. Be careful when you are using maven eclipse plug-in.
#####a. Don't use below maven archetects in Eclipse JEE, they are meant for RAD.
- webapp-jee5-was
- webapp-jee5-liberty
Nevertheless, use maven-archetype-webapp honestly.
#####b. Use Maven -> Update Project..(Alt +F5) with caution! Below error can be occurred：
[AUDIT ] CWWKF0011I: The server DemoServer is ready to run a smarter planet.
[ERROR ] SRVE0293E: [Servlet Error]-[Failed to load listener: org.springframework.web.context.ContextLoaderListener]: java.lang.ClassNotFoundException: org/springframework/web/context/ContextLoaderListener

at [internal classes]with the help of git，the above Maven->Update Project will cause .project change from
<buildCommand>
<name>org.eclipse.m2e.core.maven2Builder</name>
<arguments>
</arguments>
</buildCommand>
<buildCommand>
<name>org.eclipse.wst.validation.validationbuilder</name>
<arguments>
</arguments>
</buildCommand>to
<buildCommand>
<name>org.eclipse.wst.validation.validationbuilder</name>
<arguments>
</arguments>
</buildCommand>
<buildCommand>
<name>org.eclipse.m2e.core.maven2Builder</name>
<arguments>
</arguments>
</buildCommand>and will change .classpath from
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="maven.pomderived" value="true"/>
<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
</attributes>
</classpathentry>to
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="maven.pomderived" value="true"/>
</attributes>
</classpathentry>After I revert the changes in .classpath, the issue is resolved.
###Auto rebind configurations You don't need to do anything if you are using spring framework and you already have below piece of configuration done there.
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>Because spring framework has a built-in support for cloud and is smart enough to auto re-configure your file, it will automatically bind the environment service to this dataSource and will ignore any your configurations here given that you only have one RDBMS service bind to your application.
However, if you want more fine control over your application, you can do below things.
pom.xml for maven.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>cloudfoundry-connector</artifactId>
<version>0.9.5</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-service-connector</artifactId>
<version>0.9.5</version>
</dependency>applicationContext.mxl for spring framework.

">
<cloud:data-source id="dataSource" service-name="mysql-cyper" />
</beans>Notice the new cloud declaration, xmlns:cloud="http://www.springframework.org/schema/cloud"
and http://www.springframework.org/schema/cloud http://www.springframework.org/schema/cloud/spring-cloud.xsd
BTW, again, service-name is optional if there is only one RDBMS service bind to this app.
###Odds and ends
- You need to bind mysql service before you start application for the first time.
- You must include jars for jdbc drivers, the bluemix won't provide jdbc drivers for you.
