my bpel.xml is:
<?xml version = '1.0' encoding = 'UTF-8'?>
<BPELSuitcase>
<BPELProcess id="DB_MasterDetail" src="DB_MasterDetail.bpel">

Answer 1

i forgot to mention that i defined a
CLASSPATH=D:\OraBPELPM_1\integration\orabpel\lib\connector15.jar;D:\OraBPELPM_1\integration\orabpel\lib\olite40.jar
and added the following to Path:
D:\OraBPELPM_1\integration\orabpel\bin;D:\OraBPELPM_1\jdk\jre\bin\server
but it did not help.
