eclipse - EAR file with multiple WAR files. Sharing classes -

i using eclipse neon , maven development. there 2 main projects. project 1 contains web services including both soap , restful. has database accesses implemented. project 2 contains ui angular implementation. angular ui utilizes restful services of project 1 data access. application packaged ear file containing war files 2 projects. (this not design!!!)

there few servlet classes in ui application handles authorization issues. classes in each war file independent. need access data database tables 1 of servlet classes. since capability in project 1 should able utilize classes in project 2.

in eclipse have both projects in workspace , have added project 1 build path of project 2 can add proper objects needed project 2. however, when try build project 2 can't find classes project 1. tried adding project 1 export list of project 2 made no difference.

i can provide pom files necessary.

i don't know try.

one way share these db access features in both applications consist in packaging them common libs within ear.

see this maven documentation

just 1 remark, imo it's not pattern have multiple application accessing/modifying same data model. see this answer on question "multiple application using 1 database?" details.

so perhaps should consider keeping data model access logic in existing first war (which contain rest , soap services) , make second app backend consume new service first app example?

another option package these webapps single 1 (so single war), providing both ui , backend features (your servlets , apis together).

edit: cannot judge application design not take @ it. pointed out @david, it's not bad pattern have multiple webapps different purposes, packaged ear or not, more if these apis made different types of clients (ui, backends, etc...)
