written by Shirin , April 28, 2008

Hi,

When i come to the stage of creating a Oracle Applications Partner link, it gives WSDL Write Error and the message is The Wrapper procedure HR_MAINTAIN_PROPOSAL_API$INSE, could not be found in the package

XX_BP EL_SalaryPropasalService for the schema AP PS.

My Question is do i need to create a Wrapper before i execute this step and if i need to create what should be available in Wrapper

Apprecaite your help

Hi George,

This is a very nice and handy document for beginers. I have worked on Oracle SOA for last few months and have come across many performance related issues while designing any SOA interface.

was little bit curious if there could be any perfomance issue if we use File Adapter rather than using straight forward OS scripting.

Would you please share your views in this regard.

Many Thanks,

Debanjan

TIA
