Why don't my Toplink descriptors reflect the Java Code in the structure panel in JDeveloper? -

-

i learning oracle adf, including toplink orm. well, think toplink orm, correct me if wrong. added connection sqlite database, , generated bunch of java class. using chinook example database.

the wizard did not found foreign key mapping, tried adding one-to-many relationship between artist class , album class. added list<album> field in artist class.

public class artist implements serializable {      // existing fields, default constructor , get/set omitted      //...     private list<album> albums;      public artist(int artistid, string name, /* added */ list<album> albums) {         this.artistid = artistid;         this.name = name;         this.albums = albums;     }      //...     public list<album> getalbums() {         return this.albums;     }      public void setalbums(list<album> albums) {         this.albums = albums;     }  }

i tried told toplink album list had 1 many relationship album elements. when opened toplink mapping , tried edit descriptor, new field not present in "structure" panel. tried looking refresh button, found none. there no "add field" either. googled crazy , did not found anything. strange thing is, restarted jdeveloper, , albums field there, , able set one-to-many relationship on it...

so really, question : there way make field appear without restarting jdeveloper? old pretty fast.

the problem disappeared after few reboot. bug in jdeveloper. solution classic "three r" of computer troubleshooting.

  1. restart jdeveloper, toplink structure panel reflect java code
  2. reboot computer.
  3. reinstall jdeveloper

inconvenient... works.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
