I am handling file uploads by a multipart filter as described here. I created a WAR file and deployed on Weblogic 10.3.3 server and got error:

<Dec 8, 2011 5:37:07 PM IST> <Error> <HTTP> <BEA-101020> <[ServletContext@26087289[app:playground module:playground.war path:/playground spec-version:null]] Servlet failed with Exception

Then I deployed same WAR file on Tomcat 7.0.11 server and it is successfully running. How is this caused and how can I deploy successfully on Weblogic?

    Deployment on Weblogic 10.3.3 results in an error:

    java.lang.NoSuchMethodError: org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(Lorg/apache/commons/fileupload/RequestContext;)Ljava/util/List;

    Deployment on Tomcat 7.0.11 is successful.

    Weblogic already ships with Apache Commons FileUpload libraries. This error indicates that they are of an older version than which you have in /WEB-INF/lib.

    You have at least 3 options:

    1. Remove the JARs from /WEB-INF/lib.
    2. Replace them by exactly the same version as Weblogic is using.
    3. Change the Weblogic classloading policy to load classes from application first.
