Mapping of data object in Hibernate search is done using annotations,
However this require adding the hibernate search JAR to the classpath.

But in the UI I don't want to add Hibernate Search JAR to the UI classpath because it is a backend JAR, how can I overcome this problem?

Hi,

the easiest would be to just include the jar file. Is there any particular reason why you don't want to include it into the UI?

Otherwise two options come to my mind

• Implement a xml configuration for Hibernate Search. It should be straight forward and you would make other people happy as well - https://www.hibernate.org/443.html ;-)
• Use the maven-shade plugin to include just the annotations you need into your UI jar. This approach of course is only working in case you are using maven as build tool and one has to carefully think about the implications.
