Adding External jar file in webdynpro in CE 7.1 EHP 1

Hi,

How to add external jar file in webdynpro component. I am using CE 7.1 EHP 1 SP04 .Public part of external library is used in the webdynpro dc. I created Enterprise Application and used that in runtime in the wybdynpro dc also.

I am not getting any error at the time of deploy but at the time of activating getting the following error.

ERROR: E:\usr\sap\CED\J10\j2ee\cluster\server0\temp\CBS\1\.B\354\t\65FFED04CAA1231EE16A570686EC24D6\gen_wdp\packages\com\sap\home\ovsuser\ovsuserapp\comp\OvsUserComp.java:23: package com.sap.security.api does not exist
     [javac] ERROR: import com.sap.security.api.ISearchAttribute;
     [javac] ERROR:                             ^
     [javac] ERROR: E:\usr\sap\CED\J10\j2ee\cluster\server0\temp\CBS\1\.B\354\t\65FFED04CAA1231EE16A570686EC24D6\gen_wdp\packages\com\sap\home\ovsuser\ovsuserapp\comp\OvsUserComp.java:24: package com.sap.security.api does not exist
     [javac] ERROR: import com.sap.security.api.ISearchResult;

Please help.
