    • Property Summary Print widget and service → Print service and server-side requirements

  • Ticket #5 – Description

    v2 v4  
    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.
     1Implement 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.

     94!GeoPrisma will replace the url shown above by that of the print proxy and the various !GeoPrisma proxy parameters.  The print proxy will re-map the url to the one specified in the Apache conf file
