uploading a file using jsp and com.oreilly.servlet lib package
Sorry to bother you but I need your help folks
I am developing an application to pick up files from a database and sent to a specified location on a different system.
I am presently trying to run this code,I have placed this lib package from oreilly which is supposed to encapsulate the usage of file uploads,which is a jar file called cos.jar into C:\Program Files\Java\jdk1.5.0_03\jre\lib\ext folder .I have a jsp page that calls the bean which does the upload and implement the classes in the oreilly package.I am using tomcat 5
[b]the jsp page that acts as the user interface
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Please Choose The File</title>
</head>
<body bgcolor="#ffffff">
<table border="0"><tr>
<form action="Upload.jsp" method="post"
enctype="multipart/form-data">
<td valign="top"><strong>Please choose your document:</strong>
</td>
<td> <input type="file" name="file1">
</td></tr>
<tr><td><input type="submit" value="Upload File"></td></tr>
</form>
</table>
</body>
</html>
this is the jsp page that calls the bean
<jsp:useBean id="uploader" class="com.UploadBean" />
<jsp:setProperty name="uploader" property="dir" value="<%=application.getInitParameter(\"save-dir\")%>" />
<jsp:setProperty name="uploader" property= "req" value="${pageContext.request}" />
<html>
<head><title>file uploads</title></head>
<body>
<h2>Here is information about the uploaded files</h2>
<jsp:getProperty name="uploader" property="uploadedFiles" />
</body>
</html>
[b]this is the bean class
package com;
import java.util.Enumeration;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.ServletRequest;
import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.multipart.DefaultFileRenamePolicy;
import javax.servlet.*;
public class UploadBean {
private String webTempPath;
private HttpServletRequest req;
private String dir;
// private ServletRequest request;
public UploadBean( ) {}
public void setDir(String dirName) {
if (dirName == null || dirName.equals(""))
throw new IllegalArgumentException("invalid value passed to " + getClass( ).getName( )+".setDir");
//webTempPath = dirName;
dir = dirName;
}
/* public String getDir()
{
return webTempPath;
} */
public void setReq(ServletRequest request) {
if (request != null && request instanceof HttpServletRequest)
{
req = (HttpServletRequest) request;
} else {
throw new IllegalArgumentException("Invalid value passed to " + getClass( ).getName( )+".setReq");
}
}
public String getUploadedFiles( ) throws java.io.IOException{
//file limit size of 5 MB
MultipartRequest mpr = new MultipartRequest(req,dir,5 * 1024 * 1024,new DefaultFileRenamePolicy( ));
Enumeration enume = mpr.getFileNames( );
StringBuffer buff = new StringBuffer("");
for (int i = 1; enume.hasMoreElements( );i++){
buff.append("The name of uploaded file ").append(i).append(" is: ").append(mpr.getFilesystemName((String)enume.nextElement( ))).append("
");
}//for
//return the String
return buff.toString( );
} // getUploadedFiles
}
On running the code I find this error messages
