Method Detail

sfDeploy

public void sfDeploy()
              throws SmartFrogException,
                     java.rmi.RemoteException
Retrieve our file from our parent libraries.

  1. locate parent Library implementation
  2. get information about repository cache
  3. work out names of remote URL, local filename
  4. bind our localfilename
  5. fetch the jar (or fail)
  6. validate the JAR (or fail)

Specified by:
sfDeploy in interface Prim
Overrides:
sfDeploy in class CompoundImpl
Throws:
SmartFrogException - error while deploying
java.rmi.RemoteException - In case of network/rmi error

download

public void download()
              throws SmartFrogException
Download the file, even if it is present. Tries every repository in turn.

Throws:
SmartFrogException - if there are no repositories.

makeRepositoryUrlList

public java.lang.String makeRepositoryUrlList()
make string list of the repositories

Returns:
a (possibly empty) list of URLs

downloadFromOneRepository

public java.io.IOException downloadFromOneRepository(java.lang.String repositoryBaseURL)
                                              throws SmartFrogException
try to fetch the file from a single repository. All IOExceptions caught during fetching are logged at debug level, and turned into a failure of this method.

Parameters:
repositoryBaseURL -
Returns:
the exception that got us here
Throws:
SmartFrogException

checkMd5Checksum

public void checkMd5Checksum()
                      throws SmartFrogException
check that md5 checksum

Throws:
SmartFrogException

checkSha1Checksum

public void checkSha1Checksum()
                       throws SmartFrogException
check our sha1 checksum

Throws:
SmartFrogException

checkChecksum

public void checkChecksum(java.io.File file,
                          java.lang.String algorithm,

                          int blocksize)
                   throws SmartFrogException
check the checksum of a file. This is not hidden at download time, as we do it *every* load, even if the file is in cache. That may be overkill, but there you go.

Parameters:
file -
algorithm -
hexValue -
blocksize -
Throws:
SmartFrogException

makeRemoteUrlPath
