RSLs can be complicated to create, use, and deploy. The
following table describes common errors and techniques to resolve
#1001 Digest mismatch with RSL
This error indicates that the digest of
a library does not match the RSL SWF file. When you compile an application
that uses an RSL, you specify the library SWC file that the application
uses for link checking at compile time and an RSL SWF file that
the application loads at run time. The digest in the library’s catalog.xml
file must match the digest of the RSL SWF file or you will get this
error. If this error persists, recompile the application against
the library SWC file again and redeploy the application’s SWF file.
you are using framework RSLs, then the SWZ file is a different version
than what the application was compiled against. Check whether this
is the case by adding a failover RSL SWF file and recompiling. If
the error does not recur, then the SWZ file is out of sync.
you are creating an optimized RSL, be sure to run the digest tool
against the library.swf file after you optimized the library.swf
This error indicates that the SWZ or SWF
file is not being found.
The frequently occurs if the client
is not able to download the signed framework RSL from the Adobe
web site, and you have not deployed a local signed framework RSL.
If the client has limited or not internet connectivity, be sure
to deploy the local framework RSL to a location that is accessible
to the client. For more information, see Using the framework RSLs.
It can also occur if Flash Player
tries to load a custom RSL that is not available. For example, if
you specified only “mylib.swf” as the value of the rsl-url parameter
to the runtime-shared-library-path option, but
the SWF file is actually in a sub-directory such as /rsls, then
you must either recompile your application and update the value
of the rsl-url parameter to “rsls/mylib.swf”, or
move mylib.swf to the same directory as the application’s SWF file.
This error indicates that the loaded RSL
was not signed properly. In the case of framework RSLs, the framework’s
SWZ file that the application attempted to load at run time was
not a properly signed SWZ file. You must ensure that you deploy
an Adobe-signed RSL, or be sure to use the signed framework RSLs
that are deployed on the Adobe web site.
The cause of this error is that you do not
have a crossdomain.xml file on the server that is returning the
RSL. You should add a file to that server. For more information,
see Using cross-domain policy files.
If you are loading signed
framework RSLs from the Adobe web site, you should not get this
If you put the crossdomain.xml file at the server’s
root, you do not have to recompile your application. This is because
the application will look for that file at the server’s root by
default, so there is no need to explicitly define its location.
you cannot store a crossdomain.xml file at the remote server’s root,
but can put it in another location on that server, you must specify
the file’s location when you compile the application. On the command
line, you do this by setting the value of the policy-file-url argument
of the runtime-shared-library-path option.
the following example, the RSL SWF file is located in the /rsls
directory on www.domain.com. The crossdomain.xml file is located
in the same directory, which is not the server’s root, so it must
therefore be explicitly specified:
mxmlc -runtime-shared-library-path= ../lib/mylib.swc, http://www.mydomain.com/rsls/myrsl.swf, http://www.mydomain.com/rsls/crossdomain.xml Main.mxml
This error occurs when you try to open an
application that uses RSLs in the standalone player or in the browser
by using the file system and not a server. It means that you are
violating the security sandbox of Flash Player by trying to load
You must deploy your application and RSLs
to a network location, and request the application with a network
request so that Flash Player will load the RSL.
If you are
testing the application locally, you can add the directory to your
Player trust file to avoid this error.
Requested resource not found
You might find this error in your web server
logs. If you deploy the RSL SWF file to a location other than that specified
when you compiled the application, then you will get an error similar
to this when the application tries to run.
The solution is
to either recompile your application and correct the deployment
location of the RSL SWF file or to move the RSL SWF file to the
location that the application expects.
