Hi all,
I have read the email the from Francesco Izzi (21.04.2009). He was searching for a possibility to reload the Geoserver configuration via Rest. -> http://www.mail-archive.com/geoserver-devel@lists.sourceforge.net/msg04914.html
I had the same problem, so I tried to find a solution.
I'm not sure if the way I have implemented the function is really correct, but it seems to work.
Hoping somebody can take a look at the code to upgrade and correct it.
Justin Deoliveira provides an indication to take a look at the restconfig extension and specially at the CatalogResource Base.java.
Greetings, Lars Schrader
1. The solution should accept the following url to reload the catalog
curl -u username:password -v -XPOST http://localhost:8080/geoserver/rest/catalogreload
2.1 adding the following code into the applicationContext.xml of the restconfig extension
<entry>
<key><value>/catalogreload</value></key>
<value>catalogReloader</value>
</entry>
.............
<bean id="catalogReloader" class="org.geoserver.catalog.rest.CatalogReloader" parent="abstractCatalogFinder"/>
2.2 create a new class org.geoserver.catalog.rest.CatalogReloader
package org.geoserver.catalog.rest;
import java.util.logging.Logger;
public class CatalogReloader extends AbstractCatalogFinder {
static Logger LOGGER = Logging.getLogger( "org.geoserver.catalog.rest");
public CatalogReloader(Catalog catalog) {
super(catalog);
}
@Override
public Resource findTarget(Request request, Response response){
try{
CatalogResourceBase.reloadCatalog();
}catch(Exception e){
LOGGER.warning(CatalogReloader.class.getName()+" : catalog couldn't be reloaded.");
}
response.setStatus(Status.SUCCESS_ACCEPTED);
return null;
}
}
2.3 adding the following code into the org.geoserver.catalog.rest.CatalogResourceBase of the restconfig extension
/**
* Static method to reload the catalog
*/
protected static void reloadCatalog() throws Exception {
GeoServerLoader loader = GeoServerExtensions.bean( GeoServerLoader.class );
try {
synchronized (org.geoserver.config.GeoServer.CONFIGURATION_LOCK) {
loader.reload();
LOGGER.info(CatalogResourceBase.class.getName()+" : catalog could be reloaded.");
}
}
catch (Exception e) {
throw new RuntimeException( e );
}
}
3. After that I have created a new restconfig-1.7.x.jar with the complete restconfig extension.
The answer of the curl statement is:
< HTTP/1.1 202 Accepted
< Server: Apache-Coyote/1.1
< Date: Fri, 24 Jul 2009 08:05:01 GMT
< Server: Noelios-Restlet-Engine/1.0..8
< Transfer-Encoding: chunked
<
* Connection #0 to host localhost left intact
* Closing connection #0
4. You can also access the rest patch via java. The solution based on the email from
Santiago Montico (21.07.2009). -> http://www.mail-archive.com/geoserver-devel@lists.sourceforge.net/msg06425.html
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.ProtocolException;
import java.net.URL;
import org.apache.log4j.Logger;
import sun.misc.BASE64Encoder;
public class GeoServerCatalogReloadRest {
private static Logger geoServerCatalogReloadLogger = Logger
.getLogger(GeoServerCatalogReloadRest.class.getName());
public GeoServerCatalogReloadRest () {
}
public static Boolean doReload (String urlGeoserver, String usernameGeoserver,
String passwordGeoserver) {
String result = null;
try {
// example:
// username:admin
// password:geoserver
// url:http://localhost:8080/geoserver/rest/catalogreload
URL url = new URL(urlGeoserver + "rest/catalogreload");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
// write auth header
BASE64Encoder encoder = new BASE64Encoder();
String encodedCredential = encoder.encode((usernameGeoserver + ":" + passwordGeoserver)
.getBytes());
connection.setRequestProperty("Authorization", "Basic " + encodedCredential);
connection.setRequestProperty("Content-Type", "text/xml");
connection.connect();
result = connection.getResponseMessage();
} catch (MalformedURLException mue) {
geoServerCatalogReloadLogger.warn(GeoServerCatalogReloadRest.class.getName()
+ ": url not correct -> " + result + " : " + mue.getMessage());
return new Boolean(false);
} catch (ProtocolException pe) {
geoServerCatalogReloadLogger.warn(GeoServerCatalogReloadRest.class.getName()

return new Boolean(false);
} catch (IOException ioe) {
