Class BulkLoader

java.lang.Object
com.bea.content.loader.bulk.BulkLoader

All Implemented Interfaces

FilenameFilter

Direct Known Subclasses:

FileBulkLoader

public class BulkLoader

extends Object

implements FilenameFilter

The Content Manager bulk loader application. <p/>

This class will scan the local file system for files to load via the content manager. <p/>

BulkLoader has limited use when loading against a Library Services Enabled Repository. If the content is new (not currently loaded into the WLP Repository) and Library Services is enabled, the content may be loaded. In this case, the workflowstatus property must be specified in the md.properties, which defines the workflow status id used when the content is checked in. All lifecycle actions will operate as if the bulkloader user is a user in the admin tools. So, for example if a content item is checked in as "Ready" then the assignements will occur. Please review the Workflow javadoc for more information. <p/> The status transitions for the default workflow are as follows:

• 1 = DRAFT
• 2 = READY
• 3 = REJECTED
• 4 = PUBLISHED
• 5 = RETIRED <p/>

The type (ObjectClass) for the file along with the values of any required properties must be specified in the metata data properties file. Thus, a type must be defined in the content repository before the bulkloader may load files from the file system.

A folder will be loaded as a Hierarchy Node and a file will be loaded as a Content Node.

The actual bytes will be loaded into the primary property (must be defined in the type) and must be of type Binary.

In order for bulkloader to run, the repository and the application must be passed in as arguments and the server must be running.

This class is mainly designed to run as a command-line application, via a "java com.bea.content.loader.bulk.BulkLoader" command-line. To see a usage, give it a -h flag or read the Usage.txt in this package.

Additionally, BulkLoader objects can be created and used to provide the functionality in other places. The lifecycle of a BulkLoader is as follows:

The base directory that will be loaded may be passed in using the -d paramter. If it is not specified then the current directory "." will be used. Any additional argument will be considered a file/folder to load relative to the base directory, or if an absolute path is specified then it will be used.

For FileSystemRepositories, the "-d" parameter must be the same as the "cm_fileSystem_dir" property in content-config.xml unless the repository is managed.

Folders (directories) will automatically be assigned an ObjectClass of type (ObjectClass.FOLDER)

• Construction
• parseArgs() if not passed in to constructor.
• validateArgs() to make sure the loader has valid arguments.
• doLoad() to execute the load.

Not calling parseArgs() and validateArgs(), in that order, will cause the BulkLoader object to most likely ungracefully fail. However, once those methods have been invoked, doLoad(), can invoked.

If manually constructing and utilizing a BulkLoader object, be certain to synchronize all access to the object. Since the command-line program is single-threaded, BulkLoader objects are not thread-safe by design.

To load the default LoaderFilters, the BulkLoader looks for the com/bea/content/loader/bulk/loader.properties file in the CLASSPATH. From that it reads the list of default LoaderFilter class names from the "loader.defFilters" property. To not use any of the default filters, specify +filters in the command-line args.

fixPath

public String fixPath(String path)

Fix up a path to be forward-slash style and to not have empty path parts.

debug

public void debug(String mesg)

Out put a debug message.

Subclasses can override this method to change where messages go.

public void warning(String mesg,
                    Throwable ex)

Output a warning message.

Subclasses can override this method to change where messages go.

warning

public void warning(String mesg)

Output a warning message.

error

public void error(String mesg,
                  Throwable ex)

Output an error message.

Subclasses can override this method to change where messages go.

error

public void error(String mesg)

Output an error message.

isReadableDirectory

public static boolean isReadableDirectory(String name)

Check if the specified file name is a directory that we can get into.

isHidden

public static boolean isHidden(File f)

Check if the specified file is a hidden file.

Under UNIX, the File.isHidden() reports that "/weblogicCommerce/dmsBase/." is a hidden file, which it is not. So, this fixes that problem by getting canonicals paths for directories before calling isHidden(). That seems to do the trick.

main

public static int main(BulkLoader loader,
                       String[] args)

The main method invoked on a BulkLoader instance.

This will take a BulkLoader through the bulk loading steps. Output will be sent via the BulkLoader's debug(), warning(), and error() methods.

This will not call System.exit().

Parameters

args - the command-line args.

Returns

the exit code (0 for success, non-zero for failure).

See Also

parseArgs(java.lang.String[]), validateArgs()

main

public static void main(String[] args)

Command-line entry point.

This will call System.exit() on invalid args or error. To invoke a bulk load from your own code, create and manipulate a BulkLoader object. You can use the other main method, which does not exit.

Parameters

args - the command-line args.

main(com.bea.content.loader.bulk.BulkLoader,java.lang.String[])
