How to reuse the jakarta regexp


is it possible to reuse the jakarta regexp?

The library comes with EP60 and can be found at


I can include the library in Eclipse and compile everything fine, but get runtime errors in the portal. Being an EP development newbie I tried to declare the library in the SharingReference property of the portalapp.xml, but this did not work either.

Thanks in advance

    Hi Wilfried,

    Yes, it is possible to reuse any external common library from several applications. You have to do two steps:

    1. Add a record into cluster\server\managers\library.txt in a format:

    library library_name jar1;jar2;...jarN

    jarX is a jar location either relative from cluster\server\additional-lib or absolute

    2. Add a line to cluster\server\managers\reference.txt in a format:

    reference application library_name

    where library_name is the same as registered in library.txt

    in your case there is a registered library that includes jakarta-regexp-1.2.jar already. find in library.txt line

    library com.sapportals.dqp.lib

    if it mentions libraries your application doesn't need or finds in other places you should create a new library record otherwise just use it.

    Additional information you may find in engine's docs:

    Administration Manual->Configuration Tasks->Configuration of additional libraries.
