'IBM ODM cannot generate a valid WADL

I've been plagued for months with an error in ODM. It doesn't prevent my services from working, it only prevents ODM from automatically generating the JSON input payload when I test a service through the Rule Execution Server (the Retrieve HTDS Description File).

I attached a screenshot of the error.

What is puzzling is that:

  • if I move my variable from Input to Output, then the JSON gets generated in the Server Response section
  • if I manually enter my own JSON, the service executes correctly and I get back a decision

Does anyone have any idea what could possibly be wrong here?

Very likely your variable is not being deserialized properly. This would explain both the error you are getting and why you get it only as an input variable.

We get a similar error using a java.tim.ZonedDateTime with ODM 8.9.1, which does not support the java.time package. We just ignore the error -- and are hoping we can avoid it when we move to ODM 8.10.2.

Solution 2:[2]

hard to help as some of the context is missing. However the symptoms you describe tells there is a serialization issue one of the class of the HTDS interface.

It could be :

  • a getter/setter missing
  • a dependency missing in the XOM (classloader)
  • or a @jsonIgnore missing on a non getter/setter method whose name starts by get or set.
