Howdy, CFers! We've got an incredibly frustrating situation with a CF Web Services-based API that we wrote and maintain. We had an API in place for years that was stable and working happily with Ruby, PHP, and ColdFusion clients. Then this year a .NET client came along, and we found that our web service was not interoperable with statically-typed languages due to our extensive use of structs.
We eventually realized we had to re-write the API without structs, and we've done so. It now uses scaler values, arrays, and CFCs (which get translated to SOAP complexTypes). The .NET client is happy, and we wrote proof-of-concept clients in about 6 different languages to ensure that we'd be interoperable this time around. To our great dismay, it appears that our ColdFusion 7 servers can't serve the new API reliably. It works for about a day or so after restarting, then the clients start getting errors like: Error: coldfusion.xml.rpc.CFCInvocationException [java.lang.ClassNotFoundException : tafkan.remote_api.pfapi.v.trunk.rsp_pf_survey_status_array] and java.lang.NoClassDefFoundError: tafkan/remote_api/pfapi/v/trunk/pf_unit Restarting the CF instances is the only way to make the problem go away. A lot of time and money was put into rebuilding the API, so everyone is really at wit's end about this. We've noticed that the WEB-INF/cfc-skeletons directories of our CF instances eventually seem to have two copies of the classes for each of the CFCs used by the API. For example: -rw-r--r-- Feb 17 09:15 remote_api.pfapi.v.trunk.pf_datum.class -rw-r--r-- Feb 3 12:20 tafkan.remote_api.pfapi.v.trunk.pf_datum.class It seems like the errors are coming from a namespace or class search path problem, so we tried switching all CFC references to be fully-qualified (dot notation starting with a mapping) instead of just simple references to CFCs in the current directory. This seemed promising, but the problem came back within 24 hours. Environment: ColdFusion 7,0,2,142559 with hf702-70523, 2-instance cluster Sun Java 1.4.2_13 Apache 2.0.52 Centos 4.5 32-bit Maybe upgrading one of these venerable pieces of software would help? Maybe upgrading just AXIS? We need help! I'm sure that there is someone out there with more CF/AXIS/SOAP experience than us that can help us get this problem resolved. Adobe support doesn't seem to be an option, as CF7 is EOL'ed and in extended-extended support (and that just for a few more days). We will pay the right person good money to help us figure this out. If you're that person, or think you might know who they are, please contact me ASAP! Thanks for reading this mega-post!
