You'll have to add more details on what exact issues you are running into, including the URLs you access, the response codes you get and what it means when you say "css styling are coming different". Which exact version of WildFly 10 are you using?
We are using wildfly 10.1.0
If I deploy following html page with just tinymce into wildfly
<h1>TinyMCE Quick Start Guide</h1>
<textarea id="mytextarea">Hello, World!</textarea>
It loads the editor correctly first, then overrides the editor part with non editable tinymce editor.
Please let me know you need any further information
