 com.sun.midp.jump.installer.JUMPInstaller
All known Subclasses: com.sun.midp.jump.installer.JUMPFileInstaller,
| JUMPInstaller | | abstract public class JUMPInstaller (Code) | | An JUMPInstaller manages MIDlet suites and libraries
present in a Java application environment. An MIDlet suite
distributed as a descriptor and JAR pair.
The descriptor identifies the configuration and contains security
information and the manifest of the JAR describes the contents.
The implementation of an JUMPInstaller is
specific to the platform and provides access to
procedures that make an MIDlet suite visible to users.
Each installed package is uniquely identified by a storage name
constructed from the combination
of the values of the MIDlet-Name and
MIDlet-Vendor attributes.
The syntax and content of the strings used to identify
installed packages are implementation dependent.
Only packages installed or upgraded using this API appear
in the list of known packages.

refer to an application descriptor.
If the component to be installed is the same as an existing
component (by comparing the MIDlet-Name,
MIDlet-Vendor attributes)
then this install is an upgrade if the version number is greater
than the current version. If so, the new version replaces in its
entirety the current version.
It is implementation dependent when the upgraded component is
made available for use.
The implementation of install must be robust in the presence
of failures such as running out of memory. If this method
throws an exception then the package must not be installed
and any previous version of the component must be left intact
and operational.
To receive status updates and installer warnings, provide an install
listener. If no listener is provided all warnings will be thrown
as exceptions.
Parameters:
location - the URL from which the application descriptor can beupdated
Parameters:
storageId - ID of the storage where the suite should be saved
Parameters:
force - if true the MIDlet suite components to beinstalled will overwrite any existing components withoutany version comparison

| isJadSigned | | public boolean isJadSigned()(Code) | | Checks to see if the JAD has a signature, but does not verify the
signature. This is a place holder the the Secure JUMPInstaller and
just returns false.
true if the JAD has a signature |
| isSameUrl | | abstract protected boolean isSameUrl(String url1, String url2)(Code) | | Compares two URLs for equality in sense that they have the same
scheme, host and path.
Parameters:
url1 - the first URL for comparision
Parameters:

| postInstallMsgBackToProvider | | protected void postInstallMsgBackToProvider(String message)(Code) | | Posts a status message back to the provider's URL in JAD.

| processPreviousRMS | | protected void processPreviousRMS() throws IOException(Code) | | If this is an update, make sure the RMS data is handle correctly
according to the OTA spec.
From the OTA spec:
The RMS record stores of a MIDlet suite being updated MUST be
managed as follows:
-
If the cryptographic signer of the new MIDlet suite and the
original MIDlet suite are identical, then the RMS record
stores MUST be retained and made available to the new MIDlet
suite.
-
If the scheme, host, and path of the URL that the new
Application Descriptor is downloaded from is identical to the
scheme, host, and path of the URL the original Application
Descriptor was downloaded from, then the RMS MUST be retained
and made available to the new MIDlet suite.
-
If the scheme, host, and path of the URL that the new MIDlet
suite is downloaded from is identical to the scheme, host, and
path of the URL the original MIDlet suite was downloaded from,
then the RMS MUST be retained and made available to the new
MIDlet suite.
-
If the above statements are false, then the device MUST ask
the user whether the data from the original MIDlet suite
should be retained and made available to the new MIDlet
suite.
exception:
IOException - if the install is stopped |
| setUnsignedSecurityDomain | | public void setUnsignedSecurityDomain(String domain)(Code) | | Sets security domain for unsigned suites. The default is untrusted.
Can only be called by JAM for testing.
Parameters:

| transferData | | protected int transferData(InputStream in, OutputStream out, int chunkSize) throws IOException(Code) | | Function that actually does the work of transferring file data.
