It is saying NullPointerException. Means that you are assiging or using any object which is having a null value.
You can fix it in two ways
1. You have to put consecutive System.out.println() in your jsps whereever you suspect the error. then you can see the console upto what statements printed. Then you can find the statement which cause error.
2. Go to the work\Catalina\localhost\<application_name> of your tomcate installation find the file familyhistory_jsp inside somewhere of it. Then go to the line number 144 as per your stack. you can get that statement which cause errot. This will require aditional knowledge of sevlet and compilation of jsp into servelet as well.
