We have seen this issue before in 2 scenarios on Tomcat:
- problem of sync between the cache and the actual war file. Not sure where the cache is stored in WS from memory but you could try to delete the cache
- war file not correctly built. You said you redeployed. If cache deletion does not work, can you expand (did you predeploy or predeploy+deploy with wdeploy or just took the file and redeployed it in the console)?

Hope this helps
