[GeoNetwork-devel] Integrating Geonetwork with External application

Kumaran_Narayanaswam · January 30, 2012, 10:55am

Hello,

We have an external application which lists metadata as hyper links and when the user clicks a metadata link it should open the geonetwork metadata edit page

I tried a sample code to test this approach and always get You may not have the privileges to do this operation.ServiceNotAllowedEx : Service not allowed.

I am passing the admin/admin as default username and password to the below code.

//Geonetwork Login code

……

Cookie loginCookie = httpClient.getState().getCookies()[0];

String cookieName = loginCookie.getName();

String cookieValue = loginCookie.getValue();

System.out.println("cookieName : "+cookieName);

System.out.println("cookieValue : "+cookieValue);

// encode user name and password

// set default authenticator

//javax.servlet.http.Cookie gnCookie = new javax.servlet.http.Cookie(cookieName, cookieValue);

response.addHeader(“Accept”, “text/plain,application/xhtml+xml,application/xml;q=0.9,/;q=0.8”);

response.addHeader(“Content-Type”, “application/x-www-form-urlencoded”);

response.addHeader(“Connection”, “Keep-Alive”);

response.addHeader(“Keep-Alive”, “300”);

response.addHeader(“Cookie”, cookieValue);

//response.addCookie(gnCookie);

response.sendRedirect(“http://localhost:8081/geonetwork/srv/en/metadata.edit?id=1”);

For example after Login the following is printed

cookieName : JSESSIONID

cookieValue : 88F9E1ECB7F6BAADC6CF429DCE01A9EF

and when the http://localhost:8081/geonetwork/srv/en/metadata.edit?id=1 is been called I note a different session Id printed in Jeeves Log. Why is that the session id being passed being not considered?

Any inputs on this will be really helpful.

I would look into httpclient’s cookie handling. It does an acceptable job, you shouldn’t have to add the header explicitely.

Also are there proxies in the way?

Jesse,

The idea is to forward the response to the browser and open it as a web page. With HttpClient we are able to access the url and the response is returned as html content, but rather than returning the response we want the response to be forwarded to a web browser as if the user accesses the url in web browser

There are no proxies. Thanks.

Regards

Kumaran
