Installation

To send errors to Rollbar from your Java application, you should use our rollbar-java package.

compile('com.rollbar:rollbar-java:1.0.0')

rollbar-web

If your web server is implemented as a Servlet, you can configure and enable Rollbar entirely within your WEB-INF/web.xml file using rollbar-web:

<?xml version="1.0" encoding="UTF-8"?>
<web-app ...>
    <!-- Rollbar listener and filter -->
    <listener>
        <listener-class>com.rollbar.web.listener.RollbarRequestListener</listener-class>
    </listener>

    <filter>
        <filter-name>Rollbar Filter</filter-name>
        <filter-class>com.rollbar.web.filter.RollbarFilter</filter-class>
        <init-param>
            <param-name>access_token</param-name>
            <param-value>[{{ server_access_token }}]</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>Rollbar Filter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- Servlets -->
    <servlet>
        <servlet-name>hello</servlet-name>
        <servlet-class>com.yourdomain.yourapp.servlet.HelloRollbarServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>hello</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
</web-app>

rollbar-web exposes a request listener and a filter which can be used to report all errors that occur during the request lifecycle to Rollbar. You can see a rollbar-web example on GitHub.

Configuration

All configuration is done via the Config object in rollbar-java. You can see the interface here.
