Problem:  While executing an API calling a File-AID Data Privacy project, an error was received: 
SEVERE: UnsatisfiedLinkError 
java.lang.UnsatisfiedLinkError: no disguise in java.library.path
The cause of this issue is a missing disguise library when using the legacy encryption method with an API calling a Data Privacy project.
 
Solution: Copy the disguise library and specify it in the Path environment variable.
 

Note: A system administrator may be needed to make the required changes.
 

1. Copy the library from a File-AID/EX installation 

If File-AID/EX is not installed on the machine running the API, either install File-AID/EX or simply copy the disguise library from another File-AID/EX installation. The library is specific to the platform where the API is running (32 or 64 bit).

  • On Windows, the main installation folder will have either a disguise_x86.dll (32 bit) or disguise_amd64.dll (64 bit).
  • On UNIX, the library will be named libdisguise.so. 
 

2. Specify the library in the Path environment variable 

After copying the library, it should be specified in the Path environment variable.

  • On Windows, this is done from System > Advanced System Settings > Environment Variables > System variables. Edit the Path value to include the disguise dll file path.
  • On UNIX, it should be added to the .sh script as follows: export LD_LIBRARY_PATTH=$LD_LIBRARY_PATH:/u/usersdir/libdisguisedir (where /u/usersdir refers to the location of the libdisguise.so). The library must also be executable, so running a chmod 775 command against the file may be necessary.
