Help request for using API to change WSDL file path

Hello,

I'm newly using SoapUI (API) to do some testing. And meet a problem here. I'm using SoapUI software to create a project file named as "project.xml", in which, the WSDL xsd file is defnined as a local path.

And currently, I'm using the JAVA API (WsdlProject) to load the this project.xml in another mochine, and I got the exception that, the xsd file doesn't exist.

I know that I must update the xsd file path before load the project, but I don't know how can I do that. Can any people help on this?

Thanks!
