Looks like Apex listener 1.1.4 requires Weblogic 10.3.3 and above.
This requirement exists since the first release.
Would someone know where can i download an earlier Apex listener compatible with WLS 10.3.2
You could try to use the current release anyway, but possibly you'll encounter problems, e.g. because libraries like the Java Servlet API are too old.
But why don't you consider updating your WLS?
