What are you talking about? Your custom SB code should not ever call a remote API, those are for use in the browser only.

RE: i unable to get custom API Jsonws URL using service builder

I am not sure, what your question is, but you have a Null Pointer Exception here:

    at com.travel.management.service.ExpenseLocalServiceUtil.createExpense(ExpenseLocalServiceUtil.java:64)
    at com.travel.management.portlet.TravelManagementPortlet.actionAdd(TravelManagementPortlet.java:56)

Tipp: The last "Caused by: " block usually contains the really interesting exception.


Some other thoughts:

You should not use the Util classes. Instead, reference the service and let OSGI inject it. In the ServiceImpl it is also totally unnecessary to do that, since your localservice (and a few others) alre already available.

public Expense getExpenseById(long empId) throws PortalException , SystemException{
        
        return ExpenseLocalServiceUtil.getExpense(empId);
        
    }
you should change that line to

return expenseLocalService.getExpense(empId);


Another thing: You probably want to update the namespace to something more fitting for your project.
<namespace>FOO</namespace>
