Abstract: A user creates a software tool using a simple Java text markup language (JTML) interface. The user provides the JTML server with JTML pseudo code (code objects) which the JTML server recognizes, and performs routine programming tasks associated with the JTML code objects. The JTML server builds the executable JTML tool by invoking Java classes, associated with the code object, which are necessary to create the tool. The Java classes also create the user interface necessary for the user to enter data and commands for executing the JTML tool once the tool has been created. The JTML server acts as a secure port to the host by insulating the host contact or connection from a client. No code or command passes directly between the host and the client, instead the JTML server mediates all transactions between the two. Additional security is provided by the JTML server logging each user's access and each user's transaction.
