I want to define two servlets in my Spring web.xml - one for the application html/jsp pages, and one for a web service that will be called by an external application. Here is the web.xml:
<servlet>
<servlet-name>myservlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>myservlet</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/user-service-servlet.xml</param-value>
</context-param>
<servlet>
<servlet-name>user-webservice</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>user-webservice</servlet-name>
<url-pattern>/UserService/*</url-pattern>
</servlet-mapping>
If I have myservlet use the DispatcherServlet in the file by itself, it works fine. If I have the user-webservice with the context-param for it's config file (user-service-servlet.xml), it works fine. However, if I have both in the file, then the myservlet doesn't work as the myservlet-servlet.xml file isn't loaded automatically. If I remove the context-param, then the myservlet works, but the user-webservice doesn't work as it's configuration file (user-service-servlet.xml) isn't loaded.
How can I have both servlets defined and both of their configuration files loaded?
As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:
<servlet>
<servlet-name>myservlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>myservlet</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/applicationContext.xml
/WEB-INF/user-webservice-beans.xml
</param-value>
</context-param>
<servlet>
<servlet-name>user-webservice</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>user-webservice</servlet-name>
<url-pattern>/UserService/*</url-pattern>
</servlet-mapping>
I know this is a bit old but the answer in short would be <load-on-startup> both occurrences have given the same id which is 1 twice. This may confuse loading sequence.
Use config something like this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>myservlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet>
<servlet-name>user-webservice</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
and then you'll need three files:
The *-servlet.xml files are used automatically and each creates an application context for that servlet.
From the Spring documentation, 13.2. The DispatcherServlet:
The framework will, on initialization of a
DispatcherServlet, look for a file named [servlet-name]-servlet.xml in theWEB-INFdirectory of your web application and create the beans defined there (overriding the definitions of any beans defined with the same name in the global scope).
