use custom swrl built-in problem

[zzw95]

Hi,
I have downloaded this example project, and transfer it to a jar file , and put the jar file to path "G:\Protege-5.0.0\plugins".
But in Protege , I use the "strings:" in a swrl rule , it shwos the error"Prefix not reistered for prefix name",even if I create the prefix "strings".
Cheers.

I had the same experience when testing the library in Protege 5.2. The reason seems to be that the prefix is not registered in the SWRLBuiltInManager.java class. I forked this project to https://github.com/i3mainz/swrlapi-swrlgeo and could use the prefix as intended in the testing class when modifying SWRLBuiltInManager.java to include my prefix. In Protege this still does not seem to work properly as it seems. I speculate that the SWRLBuiltInManager.java class included in Protege 5.2 is loaded instead of my modified class and therefore does not include the prefix. Would appreciate any hint of how to fix this problem permanently.
