Class PVCBufferUrlCmdImpl

  • All Implemented Interfaces:
    AccCommand, ControllerCommand, ECCommand, ECTargetableCommand, PVCBufferUrlCmd, Protectable, com.ibm.websphere.cache.Sizeable, com.ibm.websphere.command.CacheableCommand, com.ibm.websphere.command.Command, com.ibm.websphere.command.CommandCaller, com.ibm.websphere.command.TargetableCommand, java.io.Serializable

    public class PVCBufferUrlCmdImpl
extends ControllerCommandImpl
implements PVCBufferUrlCmd
    Buffers parameters in the request and executes target command with buffered parameters. This command is provided for cellular phones which have limitation in length of HTTP request header. The command enables to input long value of parameters by buffering parameters in database.

    Behaviour

    1. Checks parameters and changes succeeding process
    2. If parameter b_new is specified:
      1. Creates a new record in PVCBUFFER table and redirects to specified URL
      2. Redirects to the URL specified by b_new
    3. If parameter b_update is specified:
      1. Checks expiration of buffered parameters
      2. Merge parameters in request with parameters in database and stores merged parameter to the database
      3. Redirects to the URL specified by b_update
    4. If parameter b_exec is specified:
      1. Checks expiration of buffered parameters
      2. Merge parameters in request with parameters in database and stores merged parameter to the database
      3. Add buffered parameters to the target command and executes target command.
