Use the findByMultipleParameters bo operation in application service

Question

Hi
I am trying to use the default findByMultipleParameters operation of a business object in an application service.
I want to use the application service exposed as a webservice within webdynpro.
But how can I pass all the parameters i a way, that it is not necessary to fill all fields in webdynpro? Is there any example code?
Any help would be appreciated.

Hi Ketan,
You can implement findAll or findById in application service. First while defining the operations set the output parameter to be a structure which contains that BO(You create yourself a complex structure for it-there you can set cardinality).
Then in the application service under that operation using the service Bean of the BO access the Bo's corresponding methods(either findById or findAll). Get that output and set it in the output parmeter and return it.
public com.caf.types.FindAllAmendmentsResMsg findAllAmendments(
               @javax.jws.WebParam(name="inputParameter1")
               com.hcl.xapps.ipr.caf.types.FindAllAmendmentsReqMsg inputParameter1) {
          FindAllAmendmentsResMsg response = new FindAllAmendmentsResMsg();
          try {
               List<Amendment> amendmentList = new ArrayList<Amendment>();
               amendmentList = (List<Amendment>) this.getAmendmentService().findAll();
               response.setAmendmentList(amendmentList);
          } catch (CAFFindException cfe) {
          return response;
The above is an example for findAll.
Hope it helps you
