A alguns dias atr\u00e1s na lista GeoServer-BR<\/a>, um usu\u00e1rio precisou recarregar o cat\u00e1logo de Geoserver sem precisar reiniciar o servi\u00e7o. \u00c9 poss\u00edvel recarregar o cat\u00e1logo usando o m\u00f3dulo de LWP no Perl, sempre que uma nova layer for adicionada ao Geoserver. Se voc\u00ea tiver o Perl, o seguinte c\u00f3dio deve servir para voc\u00ea tamb\u00e9m:<\/p>\n

[source language=”:Java”]
\n#!\/usr\/bin\/perl<\/p>\n

use HTTP::Request::Common;
\nuse HTTP::Cookies;
\nuse LWP 5.64;
\nuse strict;<\/p>\n

reload_geoserver_catalog();<\/p>\n

sub reload_geoserver_catalog {
\n my $browser = LWP::UserAgent->new;
\n my $cookie_jar = HTTP::Cookies->new;<\/p>\n

#Perform geoserver authentication:
\n my $url =
\n ‘http:\/\/localhost:8080\/geoserver\/admin\/loginSubmit.do’;
\n my $response = $browser->request(POST $url,
\n [‘username’ => ‘someusername’,
\n ‘password’ => ‘somepassword’,
\n ‘submit’ => ‘Submit’]);<\/p>\n

die "Error: ", $response->header(‘WWW-Authenticate’) ||
\n ‘Error accessing’,
\n # (‘WWW-Authenticate’ is the realm-name)
\n "\\n ", $response->status_line, "\\n at $url\\n Aborting"
\n unless $response->is_success;<\/p>\n

$cookie_jar->extract_cookies($response);<\/p>\n

#Load the new catalog:
\n $url =
\n ‘http:\/\/localhost:8080\/geoserver\/admin\/loadFromXML.do’;
\n my $req = new HTTP::Request POST => $url;
\n $cookie_jar->add_cookie_header($req);
\n $response = $browser->request($req);<\/p>\n

#Finally, logout:
\n $url =
\n ‘http:\/\/localhost:8080\/geoserver\/admin\/logout.do’;
\n $req = new HTTP::Request POST => $url;
\n $cookie_jar->add_cookie_header($req);
\n $response = $browser->request($req);
\n}

Se voc\u00ea estiver usando Linux, voc\u00ea poderia tamb\u00e9m usar o comando curl<\/strong>, que pode realizar o mesmo objetivo. Veja como utilizar o curl, neste link<\/a>.
\nPara utilizar Java, segue o c\u00f3digo bastando apenas alterar o username\/password:<\/p>\n

[source language=”:Java”]
\n\/\/ do login
\n URL url=new URL("http:\/\/localhost:8080\/geoserver\/admin\/loginSubmit.do?username=goeserverUser&password=geoserverPassword&submit=Submit");
\n URLConnection conn = url.openConnection();
\n InputStream inStream = conn.getInputStream();
\n String responseString=new String();
\n BufferedReader in = new BufferedReader(new InputStreamReader(inStream));
\n while(in.ready())
\n { responseString+= in.readLine(); }
\n System.out.println("———\\nresponseString:"+responseString);<\/p>\n

\/\/ reload
\n String cookie=conn.getHeaderField("Set-Cookie");
\n System.out.println("cookie-text:"+cookie);
\n cookie = cookie.substring(0, cookie.indexOf(";"));
\n String cookieName = cookie.substring(0, cookie.indexOf("="));
\n String cookieValue = cookie.substring(cookie.indexOf("=") + 1, cookie.length());
\n String cookieString=cookieName+"="+cookieValue;
\n URL url2=new URL("http:\/\/localhost:8080\/geoserver\/admin\/loadFromXML.do");
\n URLConnection conn2 = url2.openConnection();
\n conn2.setRequestProperty("Cookie",cookieString);
\n \/\/ set the Cookie for request
\n conn2.connect();
\n inStream = conn2.getInputStream();
\n in = new BufferedReader(new InputStreamReader(inStream));
\n responseString=new String();
\n while(in.ready())
\n { responseString+= in.readLine(); }
\n System.out.println("———–\\nresponseString:"+responseString);<\/p>\n

O c\u00f3digo seguinte \u00e9 em PHP, ele permite cadastrar uma FeatureType nova e ent\u00e3o recarregar o cat\u00e1logo. Para isso voc\u00ea necessitar\u00e1 incluir a classe HttpClient.class.php (http:\/\/scripts.incutio.com\/httpclient\/index.php<\/a>). Este c\u00f3digo \u00e9 uma parte de um c\u00f3digo que recebe apenas XML, cria uma tabela tempor\u00e1ria no PostGIS, insere o dado e finalmente registra o novo layer no GeoServer.<\/p>\n
