> Publishing Web-Services Web service is a HTTP based communication technology for computers on network. In enterprise system web-service is used to implement EDI(Web-EDI) and also to integrate smart devices. You can publish Script-Launcher programs as original web-services. Using Web-Services You can communicate with existing web-services by using methods of Session Object in scripts. As shown below, X-TEA Driver can send http-requests to web-service controler of A-Company to get http-responses. Then X-TEA Driver will parse responses to operate your database. Publishing Web-Services You can provide your own web-services to your partners, namely you implement X-TEA Server in your Tomcat to publish Script Launcher programs as web-services. As shown below, X-TEA Server recieves http-requests from B-Company System and launch a program(type of XF000) coded in the requests. And X-TEA Server will incorporate processing results of the program into responses and send them back. Let's see detail process of launching programs accoding to http request. When X-TEA Server receives an http request it will generate a session for the request. And it will scan the parameter with keyword 'function' to call the equevalent function of Script Launcher in system definition(shown as Spec in fig.). When the function terminated, the session will incorporate the result into an http response with keyword 'result' and terminate itself. Web-EDI is not an only purpose of web-services but they will help enterprise systems to integrate smart devices. X-TEA Server can communicate with those smart devices by means of http request/response. Consequently applications on smart devices do not have to have complicated codes to operate tables in the system as functions of Script Launcher do most they need to do. Procesures to set X-TEA Server as Web-Service Controler (1)Programming a function for Web-Service At first, you need to program a function of Script Launcher for web-service. Refer to a coding sample in Script Launcher. It differs from normal functions as follow. - You can not use dialogs nor call form/print functions. - You can scan parameters in http requests by reading instance.parmMap. - Y ou can send result of processing back to http responses by setting values to instance.returnMap with keyword of 'RESULT'. (2)Setting Servlet Container(Tomcat) Install Tomcat and write web.xml as follows to run X-TEA Server on the container. Rewrite "C:\XXXXX\YYYYY.xeaf" according to your environment. If you do not want to fix user, omit tags of User and Password(Then you need to put those parameters in http request with keyword of USER and PASSWORD). Value of "xeadServer.Service" with tag <servlet-class> is the name of web-service controler class of X-TEA Server. <?xml version="1.0" encoding="Windows-31J"?> <web-app> <servlet> <servlet-name>Service</servlet-name> <servlet-class>xeadServer.Service</servlet-class> <init-param> <param-name>SystemDefinition</param-name> <param-value>C:\XXXXX\YYYYY.xeaf</param-value> </init-param> <init-param> <param-name>User</param-name> <param-value>00000</param-value> </init-param> <init-param> <param-name>Password</param-name> <param-value>0000000000</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>Service</servlet-name> <url-pattern>/Service</url-pattern> </servlet-mapping> </web-app> Put web.xml and JAR files(they are in the install folder of X-TEA Driver) on Tomcat folders as follow. ../webapps (Tomcat Servlet Folder) /xteaServer (Project Folder for X-TEA Server) /WEB-INF (web.xml placed here) /lib (JAR files placed here) (3)Launching system Launch Tomcat and type URL as http://localhost:8080/xteaServer/Service in your browser(put IP address if server is not local in stead of localhost). If things are alright, it will show page as follows. Then you POST http requests into the URL via your applications to see how things work. You need to put the parameter of function ID with keyword of 'FUNCTION' in http request to be posted. Security Warning If web-service works in opened network, encode message by any means or use VPN.
