I'm trying to migrate my application from JDev 220.127.116.11.2 to 18.104.22.168.0 but even after Jdev migrate to new version, the application won't compile correct. Seems that some classes wont recognize dependecies from other package. If i have a class in Web that import a class from Model, in compile time the console give me this kind a error: "package 'xxx.yyy.www' does not exist". If i open any class that gave me this error there isn't any warning or red line showing errors, in the line of the import i can use Ctrl + right click and go to the class without problems. The dependecies between projects (web, model and ejb) are correct. I dont know what is, any help will be appreciated.
