We had the same issue when going to Tomcat 11.
You need to make two changes.
1) get the request params passed in via......... jakarta.servlet.http.Part
Like so.........
import jakarta.servlet.http.Part;
Part fileUpload = request.getPart("param-name");
if(null != fileUpload) {
fileUpload.write(targetFile.getAbsolutePath());
2)define the multi-part values in the servlet def in the web.xml...........
<servlet>
<servlet-name>uploadfile</servlet-name>
<jsp-file>/record/process/captureandconfirm.vpp</jsp-file>
<multipart-config>
<location>/web/tmp</location>
<max-file-size>20848820</max-file-size>
<max-request-size>418018841</max-request-size>
<file-size-threshold>1048576</file-size-threshold>
</multipart-config>
</servlet>
<servlet-mapping>
<servlet-name>uploadfile</servlet-name>
<url-pattern>/record/process/captureandconfirm.vpp</url-pattern>
</servlet-mapping>

Hi,
We have an Apache Wicket application that I just ported to wicket 10. The
application works as expected with the latest Tomcat 10.1.40. But our
application does not work with Tomcat 11.0.6 because file upload (multipart
processing is broken).
Apache wicket 10.x uses fileupload2.jakarta.servlet5 thus I create a branch
using fileupload2.jakarta.servlet6 (
https://mvnrepository.com/artifact/org.apache.commons/commons-fileupload2-jakarta-servlet6/2.0.0-M2)
thinking that might be the problem... But after some debugging the problem
seems to be in Http11InputBuffer and related classes (it seems the whole
package is very different from 10.x branch) or the way fileupload2 is using
them.
Has anyone experienced any similar problems?
