| 1 | | Implement the!MapFish print server; Stéphane has documented (mailing list ?) how to set up the JAVA server directly in Tomcat, that is without the need to have !MapFish Server. |
| | 1 | Implement the!MapFish print server. Here's what needs to be done. |
| | 2 | |
| | 3 | * Server-side requirements |
| | 4 | |
| | 5 | * Install Maven (http://maven.apache.org/download.html) |
| | 6 | * Put install path (on windows : C:\Program Files\apache-maven-2.2.0\bin) on the system path |
| | 7 | * Test on a commandline : ' mvn -version' |
| | 8 | * Create the war file based on directory .../geoprisma/trunk/lib/externals/mapfish-print/print-servlet |
| | 9 | * At the prompt type : 'mvn clean install' |
| | 10 | * Deploy the war file in a Tomcat container |
| | 11 | |
| | 12 | * Apache conf |
| | 13 | |
| | 14 | * In the !GeoPrisma Apache conf, create a reverse proxy to direct requests to the print server, e.g.; |
| | 15 | {{{ |
| | 16 | LoadModule proxy_module modules/mod_proxy.so |
| | 17 | LoadModule proxy_connect_module modules/mod_proxy_connect.so |
| | 18 | LoadModule proxy_http_module modules/mod_proxy_http.so |
| | 19 | LoadModule proxy_ftp_module modules/mod_proxy_ftp.so |
| | 20 | |
| | 21 | ProxyRequests Off |
| | 22 | <Proxy *> |
| | 23 | Order deny,allow |
| | 24 | Allow from all |
| | 25 | </Proxy> |
| | 26 | ProxyPass /print http://localhost:9998/print-servlet-1.2-SNAPSHOT/pdf |
| | 27 | ProxyPassReverse /print http://localhost:9998/print-servlet-1.2-SNAPSHOT/pdf |
| | 28 | }}} |
| | 29 | |
| | 30 | |
| | 31 | * Add this variable to configure the print server url: |
| | 32 | {{{ |
| | 33 | var printConfigUrl = '/print/info.json'; |
| | 34 | }}} |
| | 35 | |
| | 36 | * !GeoPrisma service implementation |
| | 37 | |
| | 38 | * Implement a new service |
| | 39 | * Implement a new 'print proxy' to that service |
| | 40 | * Make sure the print proxy can use proxy classes to resolve service url and to modify the url string contained in the JSON object sent to the print server, e.g. |
| | 41 | {{{ |
| | 42 | |
| | 43 | http://localhost:9998/print-servlet-1.2-SNAPSHOT/ |
