Abstract

A web server is connected to a terminal computer capable of performing hypertext transfer protocol communications with the web server. The terminal computer includes a browser for displaying information. The web server executes a plurality of web applications upon receiving a request from the terminal computer. The web server transmits messages output by the applications being executed to the terminal computer. The terminal computer displays messages received from the web server collectively in one window of the browser.

a message transmitting unit that transmits the messages stored in the message storing unit to the terminal computer, and

the terminal computer includes

a request sending unit that sends the request to the web server;

a message receiving unit that receives the messages from the message transmitting unit; and

a message displaying unit that displays messages received by the message receiving unit collectively in one window of the browser.

2. The web application system according to claim 1, wherein

the terminal computer is capable of being used by a plurality of users,

the request sending unit sends user identification information for identifying a user currently logged in the terminal computer when sending the request to the web server,

the message storing unit stores therein messages in association with each application identification information for each user identification information,

the message transmitting unit transmits the messages stored in the message storing unit for each user identification information to the terminal computer,

the message receiving unit receives the messages for each user identification information transmitted from the message transmitting unit, and

the message displaying unit displays messages received by the message receiving unit collectively in a separate window of the browser for each user identification information.

3. The web application system according to claim 1, wherein

the terminal computer is provided in plurality,

the request sending unit sends terminal-computer identification information for identifying a terminal computer currently in communication with the web server when sending the request to the web server,

the message storing unit stores therein messages in association with each application identification information for each terminal-computer identification information,

the message transmitting unit transmits the messages stored in the message storing unit for each terminal-computer identification information to the corresponding terminal computer,

the message receiving unit receives the messages for the terminal-computer identification information transmitted from the message transmitting unit, and

the message displaying unit displays messages received by the message receiving unit collectively in a separate window of the browser for each terminal-computer identification information.

4. The web application system according to claim 1, wherein the web server further includes a message output unit that is booted by the web applications, receives messages output from the web applications, transfers received messages to the message storing unit using an inter-process communication mechanism, and records the received messages in the message storing unit.

5. The web application system according to claim 4, wherein the web server further includes

a determining unit that determines whether number of messages present in the message storing unit exceeds a predetermined number upon receipt of a new message from the message output unit;

and

a message deleting unit that, when the determining unit determines that the number of the messages exceeds the predetermined number, deletes an oldest message from the message storing unit.

6. The web application system according to claim 2, further comprising a login accepting unit that accepts user login to the web application system and determines whether the user is an authentic user, and

the message transmitting unit transmits the messages stored in the message storing unit for a user that is determined to be authentic by the login accepting unit to the terminal computer.

7. The web application system according to claim 1, wherein the message displaying unit displays the messages in an order of time series.

8. The web application system according to claim 1, wherein

the web terminal further includes a setting unit that sets a cycle at which the message transmitting unit is to transmit the message from the message storing unit to the terminal computer, and

the setting unit includes

a cycle-extending unit that extends the cycle by a predetermined time period if a new message is not stored in the message storing unit during the cycle;

and

a cycle-shortening unit that shortens the cycle by the predetermined time period if a new message is stored in the message storing unit during the cycle.

9. A web server in a web application system in which the web server and a terminal computer capable of performing hypertext transfer protocol communications with the web server, wherein the terminal computer includes a browser for displaying information, wherein the web server includes

an executing unit capable of executing a plurality of web applications upon receiving a request to that effect from the terminal computer;

a message storing unit that stores therein messages output from each web application that is being executed by the executing unit in association with each application identification information for identifying each web application that is being executed; and

a message transmitting unit that transmits the messages stored in the message storing unit to the terminal computer.

10. The web server according to claim 9, further comprising a message output unit that is booted by the web applications, receives messages output from the web applications, transfers received messages to the message storing unit using an inter-process communication mechanism, and records the received messages in the message storing unit.

11. The web server according to claim 10, further comprising:

a determining unit that determines whether number of messages present in the message storing unit exceeds a predetermined number upon receipt of a new message from the message output unit; and

a message deleting unit that, when the determining unit determines that the number of the messages exceeds the predetermined number, deletes an oldest message from the message storing unit.

12. A computer-readable recording medium that stores therein a computer program that realizes a web-application-message displaying method on a web server and a terminal computer capable of performing hypertext transfer protocol communications with the terminal computer, the terminal computer includes a browser for displaying information, the computer program casing the computer to execute:
