Overriding MultiPartConfig
I am having trouble finding a way to override my MultiPart config. I have a servlet with a configuration in the web.xml.
<servlet>
...
<multipart-config>
...
</multipart-config>
</servlet>
However, I would like to be able to be able to configure this outside of the web.xml file so it can be changed outside of the webapp directory. Is there a way to do this from the "context" in the conf/Catalina/localhost directory?
Doing it programmatically would be ok for me as well, but I can't find anyway to access the multi-part config through the standard APIs.
I don't think I can use the annotation @MultipartConfig since I am writing something that extends javax.ws.rs.core.Application and I need to be able to configure this at startup time.
I am just using Jersey, running inside of Tomcat.
Thanks!

web.xml takes precedence over web-fragment.xml files and annotations
(Servlet spec rules for merging configuration settings).
I suspect Jersey sees there is no Servlet and defines a default.
Maybe try this and if this doesn't work ask the Jersey folks.
- Define the Servlet in web.xml
- In your ServletContextListener use
ServletContext#getServletRegistrations() and find the Servlet in
question
- Modify the MultiPartConfig for that Servlet as required.

RE: Overriding MultiPartConfig
Posted by "Mark A. Claassen" <MC...@ocie.net>.
Thanks for the reply!
I have been working this for a while and having been failing. There is so much going on here that I don't understand that I feel like such a newby.
First, when the multi-part config is in my local web.xml, everything works. However, if I remove that whole servlet from my web.xml, I see that Jersey initializes my servlet on its own first, and then my context listener tries to add it again and the registration object I get back from addServlet is null.
I assume that Jersey is doing this auto-configuration based on the annotations I use, but if this is true, why does it work when the configuration is in my web.xml? The org.apache.catalina.Wrapper created in the Application has an Overridable property, but it is false here.
Any help would be appreciated. Is this more of a Jersey question?

You can only do this if you remove the entry from web.xml.
You'd need to register the servlet in a ServletContextListener and then use ServletContext#addServlet() and then ServletRegistration.Dynamic#
setMultipartConfig()
(along with ading any other configuration / mapping required by the servlet)

@MultipartConfig has to be added to a Servlet class and can only be changed by recompilation - which is more work than changing web.xml.
