Cannot upload an image file from a deployed JSP page in Tomcat 10
1) Summary of the problem:
>From Tomcat 10 and onwards there has been a move from Java EE to Jakarta EE as

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 items = upload.parseRequest(request);
25:
26: // Process the uploaded items
27: Iterator iter = items.iterator();

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).
Re-Cannot upload an image file from a deployed JSP page in Tomcat 10
Hi Mark, If I understand well: a) I should remove the commons*.jar files from my /u01/tomcat/base/middleware/tomcat10/webapps/TESTS/WEB-INF/lib. b) I do not need to have a specific configuration for Tomcat 10 to use servlet-api and jakarta EE packages. I still do not understand the following: c) Do I use the correct servlet-api jar package ? You answered: If you are using Tomcat 10, you need to use the Jakarta EE package names. You can't use the Java EE package names. You can't use any library that uses the Java EE package names. But the servlet-api is already included in the Tomcat 10 lib. What's wrong with this ? d) Does someone know what can be the problem ? You answered: See above. You are trying to use a Java EE library with Jakarta EE. I use these modules in the JSP page: <%@ page import="org.apache.commons.fileupload.*" %> <%@ page import="org.apache.commons.fileupload.disk.*" %> <%@ page import="org.apache.commons.fileupload.servlet.*" %> <%@ page import="java.io.*" %> <%@ page import="java.util.*" %> <%@ page import="jakarta.servlet.*" %> <%@ page import="jakarta.servlet.http.*" %> <%@ page import="jakarta.sql.*" %> <%@ page import="java.sql.*" %> <%@ page import="org.apache.commons.fileupload.disk.DiskFileItemFactory" %> <%@ page import="org.apache.commons.fileupload.FileItemFactory" %> What's wrong with this ? e) Option 1, 2, 3 The JSP page has not been migrated from Tomcat X to Tomcat 10. It has been directly deployed in Tomcat 10. What is wrong in the code of my JSP page ? Thanks by advance for any indications.

Write your web application using the Jakarta EE APIs. Use the Tomcat migration tool for Jakarta EE to convert commons-fileupload-1.5.jar from from Java EE to Jakarta EE (and any other libraries using the Java EE APIs). Deploy your web application with the converted JARs. Option 2. Write your web application using the Java EE APIs and then deploy it to webapps-javaee rather than webapps and Tomcat will use the migration tool to convert your web application for you. Option 3. Write your web application using the Java EE APIs and convert it to Jkarata EE using the migration tool. Once converted, deploy it to the webapps directory. Note: If you use any deprecated Java EE APIs you may still see failures after conversion as Jakarta EE 10 most of the deprecated APIs.

Hi Thomas,
I get returned "Page no found" when I navigate through:

I don't understand the relation between the code in my JSP page and the link

I had the same issue because I used internal Tomcat classes.
In the past the servlet specification didn't have methods to deal with
multipart uploads.
Since Servlet 3.0 there are methods for retrieving the uploads:
https://docs.oracle.com/javaee/6/tutorial/doc/gmhba.html
I replace the ServletFileUpload and used standard methods like getParts().
This worked for me.

Thomas

I can go for Option 2. So, I guess I need to re-write my JSP page as if it was for Java EE for Tomcat 9 (or earlier versions) for instance, correct? You wrote "Write your web application using the Java EE APIs and then deploy it to webapps-javaee rather than webapps and Tomcat will use the migration tool to convert your web application for you". What is webapps-javaee ? How can I use it if I have a JSP page for Java EE.

There is nothing wrong with the code in the JSP page but the library you are trying to use (commons-fileupload-1.5.jar) will not work with Tomcat 10. The quickest fix is probably option 1: Use the Tomcat migration tool for Jakarta EE to convert commons-fileupload-1.5.jar from from Java EE to Jakarta EE and then use the converted JAR rather than the original. The best solution is probably the one Thomas pointed out: Option 4: Stop using commons-fileupload-1.5.jar and use the methods provided by the Servlet API to handle file uploads.

I don't ask to fix the code. I wish to understand what is wrong how it can be possibly solved keeping the format of a JSP page. You mention a servlet part, but I do not use a servlet. All the code is contained in the JSP page.

We already posted you with the docs where you can read about the necessary changes you need to make to your page, it is all written there (just call getParts() or getPart(..) on the servlet request object). You can ask about specific failures again if you have errors etc. but at least I don't fix your code to make it work - you can do that yourself and ask again if something isn't working like expected, after reading the docs we pointed you to and adapting your page.

I do not upload a (image) file to the database, but on the server (/tmp).

You can do this via web.xml. See the following SO question for an

Re: Re-Cannot upload an image file from a deployed JSP page in Tomcat 10
Hi, Thanks for all the tips. It is solved. I managed to create such a working page in Tomcat 9 (without any specific configuration). I just deployed that same page in Tomcat 10(also without any specific configuration), and it works. For the rest, I will wait for Tomcat 11. I guess it will be a more stable version.
