154.2. Configuring WAR deployments

For WAR implementations, you need to configure the servlet options in the WEB-INF/web.xml file.

Camel 2.15.x

Use relative paths for both the base.path and api.path parameters.
For example, to set up the Camel Swagger API servlet for any environment: 
...
<servlet>

  <servlet-name>ApiDeclarationServlet</servlet-name>
  <servlet-class>org.apache.camel.component.swagger.DefaultCamelSwaggerServlet</servlet-class>

<!-- Specify the base.path and the api.path values using relative notation
because the actual paths will be calculated at runtime as
http://server:port/contextpath/rest and http://server:port/contextpath/api-docs,
respectively -->
  <init-param>
     <param-name>base.path</param-name>
     <param-value>rest</param-value>
  </init-param>
    <init-param>
     <param-name>api.path</param-name>
     <param-value>api-docs</param-value>
  </init-param>
  
  <init-param>
     <param-name>api.version</param-name>
     <param-value>1.2.3</param-value>
  </init-param>
  <init-param>
     <param-name>api.title</param-name>
     <param-value>User Services</param-value>
  </init-param>
    <init-param>
     <param-name>api.description</param-name>
     <param-value>Camel Rest Example with Swagger that provides a User Rest
     service</param-value>
  </init-param>
  <load-on-startup>2</load-on-startup>
  
</servlet>            

<!-- swagger api declaration -->
<servlet-mapping>
   <servlet-name>ApiDeclarationServlet</servlet-name>
   <url-pattern>/api-docs/*</url-pattern>
</servlet-mapping>

Camel 2.14.x

Both servlets, org.apache.camel.component.swagger.spring.SpringRestSwaggerApiDeclarationServlet and org.apache.camel.component.swagger.servletlistener.ServletListenerRestSwaggerApiDelarationServlet, support the same options.
Use absolute paths for both the base.path and api.path parameters.
For example, to set up the Camel Swagger API servlet for Spring: 
...
<servlet>

  <servlet-name>ApiDeclarationServlet</servlet-name>
  <servlet-class>org.apache.camel.component.swagger.spring.SpringRestSwaggerApiDeclarationServlet</servlet-class>

  <init-param>
     <param-name>base.path</param-name>
     <param-value>http://localhost:8080/rest</param-value>
  </init-param>
    <init-param>
     <param-name>api.path</param-name>
     <param-value>http://localhost:8080/api-docs</param-value>
  </init-param>
  
  <init-param>
     <param-name>api.version</param-name>
     <param-value>1.2.3</param-value>
  </init-param>
  <init-param>
     <param-name>api.title</param-name>
     <param-value>User Services</param-value>
  </init-param>
    <init-param>
     <param-name>api.description</param-name>
     <param-value>Camel Rest Example with Swagger that provides a User Rest
     service</param-value>
  </init-param>
  <load-on-startup>2</load-on-startup>
  
</servlet>

<!-- swagger api declaration -->
<servlet-mapping>
   <servlet-name>ApiDeclarationServlet</servlet-name>
   <url-pattern>/api-docs/*</url-pattern>
</servlet-mapping>
