Almost every body working with BPEL will run in the error:
[Error ORABPEL-10902]: compilation failed
[Description]: in "C:\projects\vijfhuizen.com\trunk\src\soa\bpel\HelloWorld\bpel\HelloWorld",
XML parsing failed because "". [Potential fix]: n/a.
The JDeveloper error message does not say more, especially the last one, "Potential fix: n/a". But it is possible to get some more in depth log info. This is done via build.xml file that JDeveloper creates for your bpel process.
Do the following steps:
Change the 'verbose' setting to true in the build.properties file.
# Set verbose to true if you want to
# see verbose output from deployment tasks
verbose = true
Right click on build.xml and then run ant task 'Compile'.
Detailed result is now shown in the log.
