QUESTION
TL;DR: I have Spring MVC helloworld app that works on Tomcat 9. The same app on Tomcat 10 gives a 404 error for web request mappings.
The Problem
When deploying a Spring MVC 5 helloworld app to Tomcat 10, the app gives a 404 error for web request mappings. The same helloworld app works on Tomcat 9. It displays the helloworld message on Tomcat 9.
What I Expected
I expected the app to display the helloworld message on Tomcat 10.
Environment
- MS Windows 10
- Tomcat 10.0.2
- Spring MVC 5.3.3
Research I Performed
I researched in the Spring Reference Manual, Section on Web Servlet. I also tested Spring MVC Tutorials onlines. These tutorials worked on Tomcat 9. However, the same tutorials failed on Tomcat 10. I also performed google search on Tomcat 10. I saw references to Jakarta EE but not sure if this is the source of the issue. Java EE 8 and Jakarta EE 8 are backwards compatible.
How to Reproduce
I created a very basic helloword project to test this out. Here is the code that I'm using for the project.
pom.xml
...ANSWER
Answered 2021-Feb-16 at 09:28TL;DR: Spring MVC 5 does not run on Tomcat 10 because of the package renaming from javax.*
to jakarta.*
.
After further research, I was able to find the answer to my question. Spring MVC 5 does currently work on Tomcat 10. This is because Tomcat 10 is based on Jakarta EE 9 where package names for APIs have changed from javax.*
to jakarta.*
.
Tomcat 10 mentioned this on the download webpage:
Users of Tomcat 10 onwards should be aware that, as a result of the 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.*
tojakarta.*
. This will almost certainly require code changes to enable applications to migrate from Tomcat 9 and earlier to Tomcat 10 and later.
For Spring MVC 5, the Spring MVC DispatcherServlet has a dependency on the javax.servlet.*
package namespace. This is using the Java EE 8 javax
package naming. Since Tomcat 10 is based on Jakarta EE 9, the packages for javax
naming are not supported. This explains why Spring MVC 5 does not work on Tomcat 10.
There are github issues filed against the Spring Framework regarding this:
Spring core 5 is not starting on tomcat 10
Support for Jakarta EE 9 (annotations and interfaces in jakarta.* namespace)
In my case, instead of migrating to Tomcat 10, I will stay on Tomcat 9 until the Spring framework is upgraded to Jakarta EE 9.
QUESTION
I have followed the instructions for Azure Kubernetes deploying in the ignite 2.9 documentation https://ignite.apache.org/docs/latest/installation/kubernetes/azure-deployment. But I can't use the ignitevisorcmd.sh
If I run it I can't select the config file using the open command as it loads the config from the url https://raw.githubusercontent.com/apache/ignite/master/modules/kubernetes/config/example-kube-persistence-and-wal.xml. So I placed the config file to some location on the ignite cluster (/opt/ignite/apache-ignite/custom-config/cm-ignite.xml). I connect to one of the nodes and run the ingitevisorcmd on it. I select the config file for the open command but have the error message:
...ANSWER
Answered 2020-Dec-10 at 19:11It's not possible to run the ignitevisorcmd from the same pod in the Kubernetes that runs the ignite service node, because the TcpDiscoveryKubernetesIpFinder can't be used with different discovery ports (From the javadocs: Make sure that all Ignite pods occupy a similar discovery port, otherwise they will not be able to discover each other using this IP finder.). The discovery port is already used by the ignite server, so the visor can only be run as a separate pod.
Also the library ignite-kubernetes should be installed in order to use ignite visor:

Install example-spring
You can use example-spring like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the example-spring component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
