Netbeans fails to deploy web application on tomcat

I am using NetBeans IDE for building Servlet Applications. When I build and try to deploy on Tomcat I get the following errors-
In-place deployment at D:\SpringBootProjects\Servlets\urlrewritingsample\build\web
Deployment is in progress...

FAIL - Failed to deploy application at context path [/urlrewritingsample]

I use in my lib only the jar org.mozilla.javascript in version 1.7.5
I have no idea what it could be, I did a search so I didn't understand what it could be...
Is it environment configuration? I verified that the "AbstractExpressionCompiler" class does a "ScriptNode tree = parse(exp, engine.getJSContext(context));" Is it not something with the context of the application?

I had a jar called js.jar, from what I saw there are "rhino" classes too, in the end it was just a conflict of equal libraries, I deleted the old js.jar and kept the org.mozilla.javascript

I've some troubles with showing index.html

i've got some troubles with showing index.html. application.properties is empty. Spring boot v2.6.2, java 11, html 5.

Unexpected null-pointer-exception (NPE) in Hibernate findDirty during commit

I get the following stacktrace and I don't know where to look. Any insights? To my knowledge I'm using the entitymanager in a threadsafe way but the codebase is quite large so can't be 100% sure. Is that the direction to search for the problem?
The error happens rarely and repeating the exact same steps in the application does not trigger the bug again.

From the error, it looks like something in UserDao is not implementing Serializable. https://www.baeldung.com/java-serialization has some info on serialization, but a starting point is making your class implements Serializable.

You must see error
com.example.dao.UserDao.login(UserDao.java:31)
com.example.controller.UserController.login(UserController.java:32)
select * from user where email=? and pass=?
Probably method parameters are missing or something wrong while passing parameter in dao.
