kandi X-RAY | mysql-connector-j Summary
MySQL provides connectivity for client applications developed in the Java programming language with MySQL Connector/J, a driver that implements the Java Database Connectivity (JDBC) API and also MySQL X DevAPI. MySQL Connector/J 8.0 is a JDBC Type 4 driver that is compatible with the JDBC 4.2 specification. The Type 4 designation means that the driver is a pure Java implementation of the MySQL protocol and does not rely on the MySQL client libraries. The driver also contains an implementation of MySQL X DevAPI, an application programming interface for working with MySQL as a Document Store through CRUD-based, NoSQL operations. For more information, please visit the official MySQL Connector/J documentation.

I'm currently struggling with exposing the REST api in my project using Apache Camel. When I run the project it seems to be fine in the console, but it just doesn't work:

Answered 2022-Mar-25 at 16:33The component camel-servlet is not meant to be used in standalone mode as you are trying to do. It is meant to be used when you deploy your Camel application on a Servlet container or an Application Server.
In standalone mode, if you want to expose a rest endpoint, you should rather use a component like camel-undertow, camel-jetty, camel-netty-http or camel-platform-http (you can find the full list here).
Assuming that you want to use undertow, you will have to follow the next steps
In your pom file you need to replace camel-rest with camel-undertow, as next:

Answered 2022-Feb-27 at 18:25Luis Miguel Mejía Suárez's comment worked perfectly and was the easier approach.
In the context of this project, all I had to do was:
- Append
-SNAPSHOTto the version in/version.sbt(should not be needed normally but for this project I had to do this) - Run
sbt publishLocalin the parent project.
After this, the example project (which already targets the -SNAPSHOT version) is able to pick up the locally built package.

ANSWER
Answered 2022-Feb-23 at 22:05Your error says the interface HttpSessionIdListener cannot be found.
Looking at the Javadoc for that interface tells us it was added in Servlet 3.1 specification.
Now look at the Which version? page on the Tomcat site. There we see that Tomcat 7 supports Servlet 3.0. For Servlet 3.1, you need Tomcat 8 or later.
Be aware that Tomcat 8.0.x has been superseded by Tomcat 8.5.x.
