How to Serve Static Resources in Jersey 2.0 Using the Filter Configuration?

Jersey /* Servlet Mapping Causing 404 Errors for Static Resources

Issue:
In Jersey 2.0, mapping the Jersey url-pattern to /* results in 404 errors for all static resources (e.g., /index.html).

Solution:

With Jersey 1.x, static content can be served from the same path by using a filter instead of a servlet. Replace the provided servlet XML with the following:

<code class="xml"><filter>
  <filter-name>Jersey Filter</filter-name>
  <filter-class>com.sun.jersey.spi.container.servlet.ServletContainer</filter-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>org.frog.jump.JerseyApp</param-value>
  </init-param>
  <init-param>
    <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name>
    <param-value>/.*html</param-value>
  </init-param>
</filter> 
<filter-mapping>
  <filter-name>Jersey Filter</filter-name>
  <url-pattern>/*</url-pattern> 
</filter-mapping></code>

EDIT for Jersey 2.x:

Use the following XML configuration:

<code class="xml"><filter>
  <filter-name>Jersey Filter</filter-name>
  <filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
  <init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>org.example</param-value>
  </init-param>
  <init-param>
    <param-name>jersey.config.servlet.filter.staticContentRegex</param-name>
    <param-value>/.*html</param-value>
  </init-param>
</filter> 
<filter-mapping>
  <filter-name>Jersey Filter</filter-name>
  <url-pattern>/*</url-pattern> 
</filter-mapping></code>

Copy after login

Gradle Dependency for Jersey 2.x:

<code class="xml"><dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-server</artifactId>
  <version>${jersey2.version}</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency>

<dependency>
  <groupId>org.glassfish.jersey.containers</groupId>
  <artifactId>jersey-container-servlet-core</artifactId>
  <version>${jersey2.version}</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency></code>

Copy after login

Note:
Customize the staticContentRegex parameter in the filter configuration to serve other file types (e.g., .css, .jsp).
