Setting Up the Sample

A web application hosted in Apache Tomcat is used as the client.

Checkout the Playground sample from here using SVN.

In the pom.xml file found in the sample you checked out, uncomment the parent tag and add the groupId.

<!--parent>
        <groupId>org.wso2.identity</groupId>
        <artifactId>wso2is-identity-samples-oauth2</artifactId>
        <version>5.0.0</version>
        <relativePath>../pom.xml</relativePath>
</parent-->


<groupId>org.wso2.identity</groupId>

To generate the .war file you must run the following Apache Maven command in the sample's location using the command line.
```
mvn clean install
```
Copy the playground2.0.war file to the <TOMCAT_HOME>/webapps directory to deploy the webapp in Apache Tomcat.

Make sure to update the following parameters in the WEB-INF/web.xml file.

<servlet>
        <servlet-name>oAuth2ClientServlet</servlet-name>
        <servlet-class>com.wso2.identity.oauth.sample.OAuth2ClientServlet</servlet-class>
        <init-param>
             <description>serverUrl</description>
             <param-name>serverUrl</param-name>
             <param-value>https://localhost:9443/services/</param-value>

Tip: localhost is the server that hosts WSO2 API Manager and 9443 is the default SSL port of it.

Update param-value of setup to AM as shown below.

<servlet>
        <servlet-name>oAuth2AccessResourcePage</servlet-name>
        <jsp-file>/oauth2-access-resource.jsp</jsp-file>
        <init-param>
            <description>setup</description>
            <param-name>setup</param-name>
            <param-value>AM</param-value>
        </init-param>

Restart Apache Tomcat and access http://localhost:8080/playground2.0/ (assuming Tomcat is running on HTTP port 8080). You are directed to the landing page of the sample application. Click on Import Photos and you the following page appears.

This application is used to request access tokens using the four OAuth2 grant types.
