Chapter 5 - Configuring the Servlet for the Web Mapping Service (WMS) Table 10: Change the Function Service_Debug OGC_Compliancy_Mode Capabilities_DTD_URL Focus_Port Focus_HostName MapService_Configuration Changing the Values Service_Debug helps you to debug the WMS servlet during installation and development. By default, Service_ Debug parameter is not activated. OGC_Compliancy_Mode specifies whether the WMS servlet is running in OGC compliancy mode or not. By default, the OGC_Compliancy_Mode parameter is set to false. Capabilities_DTD_URL specifies the HTTP address of the Capabilities’s DTD (capabilities_1_0_0.dtd) that is in \webapps\wms\DTD in the folder where you installed Tomcat. By default the address is http:// [localhost]:8080/wms/DTD/ capabilities_1_0_0.dtd. Focus_Port is a number that specifies which port the Geomatica WebServer Monitor is using (see “Using the Assisted Method” on page 40). Focus_HostName specifies either the IP address or the host name where Geomatica WebServer Monitor is running (see “Using the Assisted Method” on page 40). MapService_Configuration specifies the path and file name of the XML file that the WMS servlet requires to configure itself (see “Using the Customized Method” on page 40). Since Geomatica WebServer is compliant with the Open Geospatial Web Map Server Interface Implementation Specification, it can provide a Capabilities file. The web.xml contains a list of parameters that are commented out by default, but you can use them to customize the servlet. The second set of parameters (see Table 11 and Table 12) determines the values returned in the Capabilities file. To comply with the Open Geospatial Web Map Server Interface Implementation Specification, you must enter values corresponding to your project. By default unspecified values are given the default value of “none”, except the parameter Service_Name which is “GetMap” by default. Each time you change the parameters, restart Tomcat to unload the servlet from memory. Table 11: Change the Capabilities Values (compatible with version 1.0.0 and higher) Service_Name Service_Title Service_Abstract Service_KeyWord Service_OnlineResource Service_Fees The Service_Name parameter is defined as “GetMap” within the Web Mapping Specification namespace. The Service_Title parameter contains a title to identify the server to the user. The Service_Abstract parameter is a descriptive statement about the server. The Service_KeyWord parameter provides a register of short words to help with catalogue searching. Currently, no controlled vocabulary is defined. The Service_OnlineResource parameter declares the top-level HTTP URL or home page for your service. The Service_Fees parameter indicates the fees imposed on the user. The reserved keyword “none” indicates that no fees exists. 42 PCI Geomatics
Reconfiguring Geomatica Focus Project Using EASI Table 11: Change the Capabilities Values (compatible with version 1.0.0 and higher) Service_AccessConstraint Table 12: Change the Capabilities Values (compatible with version 1.1.1 and higher) Path_Contact_Information Setting Parameters in Tomcat The Service_AccessConstraint parameter indicates the access constraints imposed on the user. The reserved keyword “none” indicates that no constraint exists. The Path_Contact_Information parameter declares the file containing the contact or support information for your service. If you are using Tomcat as your HTTP server, the parameters are set in the web.xml file found in \webapps\wms\WEB-INF in the folder where you installed Tomcat. Each time you change the parameters, restart Tomcat to unload the servlet from memory. For example, the code below sets the MapService_Configuration parameter in the web.xml file: MapService_Configuration C:\configuration.xml Reconfiguring Geomatica Focus Project Using EASI EASI is a scripting language that you can use for querying, specifying parameter values, and executing tasks. You can build an EASI script to automatically compute more complex or timeconsuming results. With EASI you can access and manipulate raster imagery, vector data, projection information, general binary files, and text files. To open the EASI Servlet: 1. Make sure that Tomcat is running and the Geomatica WebServer Monitor is running with a Geomatica Focus project. 2. Type the following in the address bar of your browser: http://[localhost]:8080/wms/EasiServlet Replace [localhost] by the name of the computer or IP address where Tomcat is installed. 3. In the EASI Editor box, type the EASI script that you want to use. For example, to open a Geomatica Focus project from a remote location, you can type: Call ReadJOLTProjectFile ("C:\\Program Files\\Geomatica_V100\\demo\\newport.gpr") 4. Click Process EASI. 5. Restart Tomcat. You can also restart Tomcat from a remote location, see “Resetting the Servlet from a Remote Location” on page 43. Resetting the Servlet from a Remote Location When you make changes in your Geomatica Focus project, you must update the MapService with the new map data set. To do this, normally you stop and restart Tomcat through the command prompt (see “Exploring the WCS Folder” on page 16). If you are at a remote location from the servlet, you can used the MapService Reset Button to stop and restart it. To reset the MapService: 1. Make sure that Tomcat is running and the Geomatica WebServer Monitor is running with a Geomatica Focus project. Geomatica WebServer Suite Installation Guide 43
