Update an existing Java/Tomcat Web Application

I need a experienced Java developer who can Update my Java Web Application to work in Tomcat 9 and to develop a password change feature. The application works perfectly on Java 8 and Tomcat 7. The Database behind is Oracle 19.

1. Support of the Tomcat Version 9:

- If i want to start my Application on Tomcat 9 i get the error message: Caused by: [login to view URL]: [login to view URL]

- The class LifecycleSupport is removed since tomcat 8.5.9

- Probably its enough just to include the class, but this might be just the tip of an iceberg of incompatibility

- The Application is using a Webservice for authentication, This is where to problem starts because the webservice is not updated by the owner anymore

- The developer should bring the application to work on tomcat 9

2. Develop a Passwordchange in the settings

- There should be a possibility to change the password for the client, because we always just give a standard password at the beginning

- The changed password has to match to the password-policies

- If the User trys to login 5 times with the wrong password he should be blocked and get an automatic email to his accont

For Development i can give you the Database Oracle 19 DUMP and the application with the neccesary .jar's and classes. The Application is in german but i can help you with translations. More information i will give you in a Videocall before we start the project. I will need everythng done in 1 Week.
