Error 500: java.lang.NullPointerException

Hello I am working on this servlet, it is a servlet in the /lib folder of my project, which I inherited from another developer. We have been making a lot of changes to the .xsl and .xml, however, it appears to be throwing an exception right here: void getDisplayLifeReviewForHome() { System.err.println ("Can't Find Display Life Review for Home !!! " ); } void getDisplayLifeReviewForUser() { System.err.println ("Can't Find Display Life Review for User !!! " ); } public String getDisplayLifeReviewForUser( BcSQLAgent agt ) throws Exception { if (getDisplayLifeReviewForHome( agt ).equals( TRUE )) { if (_displayLifeReviewForUser == null) { _loadUserValues( agt ); } return _displayLifeReviewForUser; } else { return FALSE; } } // getDisplayLifeReviewForUser() ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++It is breaking here: if (getDisplayLifeReviewForHome( agt ).equals( TRUE )) Also it does not matter if I set this line to TRUE or FALSE, it always gives the NullPointerException. Thanks,
