No.

Well, there is the "module extending a module" concept I blogged about, but you gotta look at all of the various warnings indicating why you should consider this route carefully.

Come meet me at Devcon 2017 or 2017 LSNA!

Hi David,

Thanks for your response.
I checked for alternate approach suggested by you https://web.liferay.com/web/user.26526/blog/-/blogs/extending-liferay-osgi-modules
Unfortunately its not suitable with my requirement.

Now I am trying to achieve my requirement with different approach in that I am trying to render the Categories page default by ascending order of 'SortOrder' value, that I have stored for each category in the key_, value pair.
To achieve it want to override the getCategories(Hits hits) method of 'assetCategoryLocalServiceImpl.java' file.

Could you please guide on procedure to override 'assetCategoryLocalServiceImpl.java' class.
Also, is there any document or online material is available that can help in overriding different files in Liferay 7. Till now I am able to override JSPs, wrapper class only.

Thanks in advance!
