A method and system for processing MTOM messages comprising a root document and one or more binary attachments referenced by the root document, in a Web service requester or provider. When an inbound MTOM message is received, a pipeline comprising a plurality of message handlers is selected to process the received message. The message is unpackaged by separating the binary attachments from the root document, and the pipeline properties are checked to determine if conversion of the message is required. Responsive to the result of the determination, either conversion of the message is carried out, by encoding the binary data in each of the attachments and replacing each reference in the root document to a binary attachment with the encoded data for that attachment, and processing the converted message by the pipeline, or the root document and binary attachments are processed by the pipeline.

Managing dynamically allocated memory in a computer system in which garbage collection process is scheduled separately from data processing comprises initiating a system program and providing system memory for use by the system program, the system program being arranged to provide a processing environment, initiating an application program within the processing environment for performing one or more units of processing, allocating a portion of the memory for use by the application program for performing the processing, providing a first unit of processing to the application program, determining the proportion of the provided system memory in use on completion of processing of the first unit; and if the proportion exceeds a predetermined threshold, providing a memory recovery instruction to the system program to identify elements in the system memory occupied by objects or data inaccessible to the application program and to free the elements of the provided system memory.
