public class RepositoryConfig

extends Object

Represents the configuration of a content repository. Each Repository may have specific properties that are necessary in order to be properly configured. Please see the specific repositories documentation for configuration information.

****************WARNING****************

When getting binaries from the BEA Repository (including both a binary Node Property and also a binary PropertyChoice) the default is to return the InputStream as a ByteArrayInputStream, thus consuming server memory until the bytes are released. If you application will be reading in very large files, you may switch to streaming mode. This means that the InputStream returned may read directly from a database resource, depending on the database or driver. This is accomplished by creating a property on the RepositoryConfig called "STREAMING_ENABLED" with the value set to "true". To disable streaming you must remove the "STREAMING_ENABLED" property entirely. Switching to streaming mode must be done with caution as it places additional requirements on developers using the api. The issue is that the InputStream through a BLOB, may be attached to a database connection (or other transactional resource). The use of this stream must therefore be within the context of a transaction to ensure that it is isolated from uses by other threads, etc. If you don't begin a UserTransaction before calling this method and then either commit or rollback the tx after you close the InputStream, the connection may go back into the WLS connection Pool and will be reused by another thread. This will lead to deadlocking the server. All of the BEA code that uses the api (tags, servlets, portlets and admin tools) are all protected through the use of a transaction. For those that are calling the API directly, here is an example of wrapping the call in a tx with exception handling left out

 try {
     Context initCtx = new InitialContext();
     tx = (UserTransaction)initCtx.lookup( "java:comp/UserTransaction" );
     tx.setTransactionTimeout( transactionTimeout );
     tx.begin();
     bytes = nodeOps.getPropertyBytes(nodeId, propertyId);
     // empty the bytes
 }
 finally {
     // make sure to close InputStream
     if ( bytes != null ) {
         bytes.close();
     }
     if ( tx != null ) {
         switch ( tx.getStatus() ) {
             case Status.STATUS_ACTIVE:
                 tx.commit();
                 break;
             case Status.STATUS_MARKED_ROLLBACK:
                 tx.rollback();
                 break;
             default:
                 // this is bad - an unexpected status
                 // throw exception
                 break;
         }
    }
 }
