WAR deployment to Jetty - CUBA Platform. Developer’s Manual

7.3.2. WAR deployment to Jetty

Below is an example of deployment of the WAR files to the Jetty web server. It is assumed that the application uses a PostgreSQL database.

Use Deployment settings > WAR page in Studio or just manually add the buildWar task to the end of build.gradle:
```
task buildWar(type: CubaWarBuilding) {
    appHome = '${app.home}'
    appProperties = ['cuba.automaticDatabaseUpdate': 'true']
    singleWar = false
}
```
Please note that we are building two separate WAR files for Middleware and Web Client blocks here.
Start build process by running buildWar from the Search dialog in Studio or from the command line (provided that you have created the Gradle wrapper beforehand):
```
gradlew buildWar
```
As a result, the app-core.war and app.war files will be created in the build\distributions\war project subdirectory.
Create an application home directory, for example, c:\work\app_home.
Download and install Jetty to a local directory, for example, c:\work\jetty-home. This example has been tested on jetty-distribution-9.3.6.v20151106.zip.

Create the c:\work\jetty-base directory, open the command prompt in it and execute:

java -jar c:\work\jetty-home\start.jar --add-to-start=http,jndi,deploy,plus,ext,resources

Create the c:\work\jetty-base\app-jetty.xml file with the following contents (for a PostgreSQL database named test):

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-" "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure id="Server" class="org.eclipse.jetty.server.Server">
    <New id="CubaDS" class="org.eclipse.jetty.plus.jndi.Resource">
        <Arg></Arg>
        <Arg>jdbc/CubaDS</Arg>
        <Arg>
            <New class="org.postgresql.ds.PGSimpleDataSource">
                <Set name="ServerName">localhost</Set>
                <Set name="PortNumber">5432</Set>
                <Set name="DatabaseName">test</Set>
                <Set name="User">cuba</Set>
                <Set name="Password">cuba</Set>
            </New>
        </Arg>
    </New>
</Configure>

The app-jetty.xml file for MS SQL databases should correspond to the following template:

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-" "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure id='wac' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="CubaDS" class="org.eclipse.jetty.plus.jndi.Resource">
        <Arg/>
        <Arg>jdbc/CubaDS</Arg>
        <Arg>
            <New class="org.apache.commons.dbcp2.BasicDataSource">
                <Set name="driverClassName">com.microsoft.sqlserver.jdbc.SQLServerDriver</Set>
                <Set name="url">jdbc:sqlserver://server_name;databaseName=db_name</Set>
                <Set name="username">username</Set>
                <Set name="password">password</Set>
                <Set name="maxIdle">2</Set>
                <Set name="maxTotal">20</Set>
                <Set name="maxWaitMillis">5000</Set>
            </New>
        </Arg>
    </New>
</Configure>

Optionally (for example, for MS SQL database) you may be required to download the following JARs and add them to the c:\work\jetty-base\lib\ext folder:
```
commons-pool2-2.4.2.jar
commons-dbcp2-2.1.1.jar
commons-logging-1.2.jar
```

Add the following text to the beginning of c:\work\jetty-base\start.ini file:

--exec
-Xdebug
-agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n
-Dapp.home=c:\work\app_home
-Dlogback.configurationFile=c:\work\app_home\logback.xml
# ---------------------------------------
app-jetty.xml

Copy the JDBC driver for your database to the c:\work\jetty-base\lib\ext directory. You can take the driver file from the CUBA Studio lib directory or from the build\tomcat\lib project directory. In case of PostgreSQL database, it is postgresql-9.1-901.jdbc4.jar.
Copy WAR files to the c:\work\jetty-base\webapps directory.
Open the command prompt in the c:\work\jetty-base directory and run:
```
java -jar c:\work\jetty-home\start.jar
```
Open http://localhost:8080/app in your web browser.
