Hi,
I have created file upload.jsp:
<%@ page contentType="text/html; charset=ISO-8859-2" %>
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2">
<META NAME="Author" CONTENT="Bartlomiej Pawlowski">
<title>upload</title>
</head>
<body>
<html:form action="/upload" >
File <html:file property="file" maxlength="30" styleClass="form2"/>
<html:submit>Upload</html:submit>
</html:form>
</body>
</html:html>
and ActionForm bean:
public class UploadForm extends ActionForm {
private FormFile file;
public UploadForm() {
}
public void setFile(FormFile file) {
this.file = file;
}
public FormFile getFile() {
return file;
}
}
when I submit this form I receive following exception:
Internal Servlet Error:
javax.servlet.ServletException: BeanUtils.populate

at
org.apache.struts.action.ActionServlet.processPopulate(ActionServlet.java:1910)
at
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1521)
Root cause:

What is wrong?
Who can help me?
