when change the bpel project to a java project, the new deploy descriptor doesn't work correctly, the original eclipse Apache ODE DD wizard loads all .bpel files from the bpel project and generate the deploy.xml file accordingly. But for now, our bpel project is a java project and all bpel artefacts are put into a source folder,
after build the project, all those files were copied into the project output location, so there are two .bpel files in the project for one user customized bpel file, and the old DD wizard will generate a wrong deploy.xml

so the change I do is loading .bpel file only from Source Folder of the bpel project since only the files in a source folder are deployed.
