String externalServerAddress

Syntax myPopChart.externalServerAddress = "is.mycompany.com:2001";

JavaBean Syntax <JSP:setProperty name="myPopChart" property="externalServerAddress" value="is.mycompany.com:2001" />

Description Specifies the external address and port of your PopChart Server.

The value of this string should be an IP address or domain name, followed by your server port number (e.g. 10.0.0.1:2001, imageserver.mycompany.com:2001). By default, your server port is 2001.

Clients will retrieve the generated image from this address. The address must be accessible from the client, meaning that if you are serving images outside of your company intranet, you may need to configure your firewall so that the address or port is open.

If you don't want to open another port on your firewall, you can use an HTTP redirection module to get to PopChart Server (see Chapter 12, "HTTP Redirection," in the PopChart Server User Guide). In this case, you should set this attribute to the location of the redirector (e.g. www.mycompany.com/popchart). Note that you do not have to specify a port in this case, as port 80 is assumed.

The external server address is different from the internal comm port address, which is the address that your web application server uses to communicate with PopChart Server (refer to the internalCommPortAddress attribute). Both the external and internal addresses must be specified when generating a PopChart image (except when using the JavaScript embedder, which does not use a comm port, or when setting the clusterMonitorAddress while clustering).

For more information about configuring PopChart Server ports and addresses, refer to "Setting Server Address and Ports" in Chapter 3 of the PopChart Server User Guide.
