Unable to upload files with Spring security filter in Struts2 using File upload 
interceptor
-------------------------------------------------------------------------------------------

                 Key: WW-3247
                 URL: https://issues.apache.org/struts/browse/WW-3247
             Project: Struts 2
          Issue Type: Bug
          Components: Core Interceptors
    Affects Versions: 2.1.6
         Environment: Windows XP, Vista
            Reporter: Sundeep Raikhelkar


I am able to upload files in struts2 (2.1.6), when I remove the spring security 
filter in web.xml. With spring security filter, I get a null in File object 
inside action class. That is line with code "testFile.length()" throws null 
exception. 

I have provided my code snippets below. Along with struts, I am using spring 
2.5.6 and Spring security 2.0.5.

Can anybody please help on this?

Web XML
 
<!--<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

-->

<!--
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
-->

 
Struts XML

<!--All packages extend base package--> 
<package name="base" extends="struts-default">
<interceptors>
        <interceptor-stack name="base-stack">
                <interceptor-ref name="defaultStack" />
                <interceptor-ref name="fileUpload">
                        <param name="maximumSize">10240</param>
                </interceptor-ref>
        </interceptor-stack>
</interceptors>
<default-interceptor-ref name="base-stack" />
</package> 



JSP 

<s:form action="save" method="post" enctype="multipart/form-data">
<s:file name="testFile" id="testFile"></s:file>
<s:submit></s:submit>
</s:form>

 
Action
private File testFile;

public File getTestFile() {
        return testFile;
}

public void setTestFile(File testFile) {
        this.testFile = testFile;
}

public String save(){
        byte[] testFileContent = new byte[(int) testFile.length()];
        new FileInputStream(testFile).read(testFileContent);

        //write testFileContent  to a local file
        writeFile("D:\\etl.gif",testFileContent); 
        return ActionSupport.SUCCESS;
}
