I'm trying to do upload a file using struts2 file tag. Followed all the mentioned as given in http://struts.apache.org/2.0.11/docs/file-upload-interceptor.html. but still am not able to retreive the file contents in my action class. Below is the code snippet which i added.
ApplicationResources.properties
struts.messages.error.uploading=a general error that occurs when the file could not be uploaded
struts.messages.error.file.too.large=occurs when the uploaded file is too large
struts.messages.error.content.type.not.allowed=occurs when the uploaded file does not match the expected content types specified
Struts.xml
<interceptors>
<interceptor name="servletConfig" class="org.apache.struts2.interceptor.ServletConfigInterceptor"/>
<interceptor name="fileUpload" class="org.apache.struts2.interceptor.FileUploadInterceptor"/>
<interceptor-stack name="basicStack">
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="fileUpload"/>
</interceptor-stack>
</interceptors>
<action name="uploadFile" method="uploadFile" class="com.example.MyAction">
<interceptor-ref name="fileUpload"/>
<exception-mapping exception="java.lang.Exception" result="error"/>
<result name="success">/jsp/success.jsp</result>
</action>
MyAction.java
import java.io.File;
//The below properties with getter and setter methods defined
private File subUploadFile; // The actual file
private String uploadContentType; // The content type of the file
private String uploadFileName; // The uploaded file name and path
public String uploadFile() throws Exception {
System.out.println("Inside uploadFile() .....");
System.out.println("File : " + getSubUploadFile());
System.out.println("File Name : " + getUploadFileName());
System.out.println("Content type : " + getUploadContentType());
return SUCCESS;
}
myForm.jsp
<s:form action="goSubRegn" method="POST" enctype="multipart/form-data">
<s:file size="110" name="subUploadFile"/>
All the S.O.P. are printing null
