Your web application has a dependency on the class co/com/paquetesdatos/panama/utilidades/Funciones and hence the issue.
To resolve the issue, check the existence of the file in your web application, if it is packaged.
Or find the dependency jar having the above missing class and add it to the classpath of the weblogic server and restart the server.
This way weblogic classloader will load the dependency classes and your web application will be able to reference that.
Hope this answers your question!!!
