<s:submit action="uploadSample" value="All upload" />
</s:form>

struts.xml

<interceptor-ref name="defaultStack"/>
<result name="input"> /login.jsp</result>
<result name="success">/main.jsp</result>
</action>

UploadMySample.java

public class UploadMySample extends ActionSupport {            
  private File sample;
  private String sampleContentType;
  private String sampleFileName;

  public File getSample () {
      return sample; 
  }
  public void setSample (File sample) {
      this. sample = sample;
  }
//---- here file uploading code ---//

return SUCCESS;

This is not a problem of Struts. For security reasons modern browser don't allow to set a value for file upload fields. If you want to display the file name after the upload you'll have to use simple text.
