You say you are using the API supplied with Tamino 3.1.1.4 but your original question said you were installing a new version. I guess then you are upgrading from Tamino 3114 to Tamino 3121?
If so, you are just migrating from one version of Tamino API4J to another as advised above. So you can recompile to see any deprecated classes etc, and you can execute your code using the new API jar files.
You can see the version of a TaminoAPI4J jar file by looking at the file “manifest.mf” inside the jar file (with something like winzip). For Tamino 3114, this has a line that says Specification-Version 3.1.1.6, and for Tamino 3121 it says Specification-Version 3.1.2.3. But generally its enough to say “the TaminoAPI4J version that came with Tamino x.x.x.x)”.
