# Java Web Application example

ROOT.war replaces Tomcat's default ROOT application - $TOMCAT_HOME/webapps/ROOT

## Pre-requisites

* [sdkman](https://sdkman.io/install)

    Install and use JDK 18

    ```bash

    sdk install java 18.0.2-tem

    sdk use java 18.0.2-tem

    ```

* [Apache Maven](https://maven.apache.org/install.html)

  Install Apache Maven 3.9.9

    ```bash

    sdk install maven 3.9.9

    sdk use maven 3.9.9

    ```

* [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)

## Test with Jetty web server

```shell

git clone [email protected]:AndriyKalashnykov/tomcat-root-war.git

cd tomcat-root-war

mvn clean package jetty:run

xdg-open http://localhost:8080/index.html

```

Access http://localhost:8080/index.html or see [Tomcat ROOT WAR Web Application UI](https://github.com/AndriyKalashnykov/tomcat-root-war/blob/master/README.md#java-web-application-ui)

## Create WAR file

```shell

git clone [email protected]:AndriyKalashnykov/tomcat-root-war.git

cd tomcat-root-war

mvn clean install

```

### Building WAR in a Secure environmets that enforce SSL

```shell

mvn clean install -Daether.connector.https.securityMode=insecure -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true

```

## List content of generated WAR file

```shell

jar tf ./target/ROOT.war

```

## Replace TOMCAT ROOT application

Edit `$TOMCAT_HOME/conf/server.xml`: `autoDeploy` and `deployOnStartUp` needs to be set to `false`

```xml

```

Remove default ROOT folder and copy ROOT.war

```shell

rm -rf $TOMCAT_HOME/webapps/ROOT/

rm -f $TOMCAT_HOME/webapps/ROOT.war

cp ./target/ROOT.war $TOMCAT_HOME/webapps/ROOT.war

```
