1) Summary of the problem:
>From Tomcat 10 and onwards there has been a move from Java EE to Jakarta EE as
>part of the transfer of Java EE to the Eclipse Foundation, the primary package
>for all implemented APIs has changed from javax.* to jakarta.*.
I have a JSP page deployed in Tomcat 10 that is intended to upload a file from
the desktop (Windows 10) to the server where Tomcat 10 is running (OEL 8).
I am unable to upload an image, and I get this error:
-
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: [24] in the jsp file: [/index.jsp]
The type javax.servlet.http.HttpServletRequest cannot be resolved. It is
indirectly referenced from required type
org.apache.commons.fileupload.servlet.ServletFileUpload
21: ServletFileUpload upload = new ServletFileUpload(factory);
22:
23: // Parse the request
24: List<FileItem> items = upload.parseRequest(request);
25:
26: // Process the uploaded items
27: Iterator<FileItem> iter = items.iterator();

My application name: TESTS
I have these libraries for the TESTS application:
/u01/tomcat/base/middleware/tomcat10/webapps/TESTS/WEB-INF/lib:
commons-fileupload-1.5-test-sources.jar
commons-fileupload-1.5-tests.jar
commons-fileupload-1.5-sources.jar
commons-fileupload-1.5-javadoc.jar
commons-fileupload-1.5.jar
I have in my Tomcat 10 this library:
/u01/tomcat/base/middleware/tomcat10/lib:
-rw-r--r--. 1 tomcat tomcat 365905 Apr 25 12:16 servlet-api.jar
2) The deployed JSP page:
-

<%@ page import="java.io.*" %>

<%@ page import="java.sql.*" %>
<%@ page import="org.apache.commons.fileupload.disk.DiskFileItemFactory" %>
<%@ page import="org.apache.commons.fileupload.FileItemFactory" %>
<%
// Set the upload directory
String uploadDir = "/tmp/";
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
List<FileItem> items = upload.parseRequest(request);
// Process the uploaded items
Iterator<FileItem> iter = items.iterator();
while (iter.hasNext()) {
FileItem item = iter.next();
// If the item is a file, save it to the upload directory
if (!item.isFormField()) {
String fileName = new File(item.getName()).getName();
String filePath = uploadDir + fileName;
File uploadedFile = new File(filePath);
item.write(uploadedFile);
}
}

I have found that it looks like:
https://www.linuxquestions.org/questions/linux-server-73/fileupload-class-not-working-with-tomcat-10-a-4175710078/
But in my situation, it seems to be a different problem.
Does someone know if this is related to a bug ?
Do I use the correct servlet-api jar package ?
Do Tomcat 10 need to be specifically configured for using servlet-api and
jakarta EE packages ?
Does someone know what can be the problem ?
Thanks by advance for any tip(s) and/or suggestion(s).
