A group of protocols is described that establish an information bus. The protocols allow various applications and components to plug into the information bus. As a member of the bus, each application or component can exchange information with any other application or component in a structured way. The information bus is especially useful in interconnecting Java beans and applets in a Java virtual machine and in a distributive computer environment. An apparatus is disclosed that is utilized to produce data from an application to an information bus for sharing the data with other applications utilizing the information bus. The data producing apparatus comprises a data element building logic, which builds data elements containing the data within the application, a data notification logic, which notifies the information bus of the availability of the data element, and a data element transfer logic, which transfers data element from one application to another. An event listing logic can also be included that is utilized to listen for data element requests from applications utilizing the information bus. The data element builder logic may be configured to change the data within a data element and the data notification logic may be configured to announce the data change across the information bus to at least some of the applications. The data element builder logic specifies the data name using either a property or a parameter. The data element builder logic also provides a view associated with the data item where the data item is a java object. The data element builder logic may also remove data elements for access while the data notification logic notifies the information bus of the removal of the particular data elements.
