Hello colleagues.

I'm having trouble with creating and using a Proxy Bridge .

I use this instruction: https://help.sap.com/viewer/b0cc1109d03c4dc299c215871eed8c42/Cloud/en-US/ed1c6732d4214c68846ab9813b9...

After deploying app in SCP I try open this link, but have error.

What could be the problem and what I am doing wrong?

Thanks in advance for the answers)

Servlet code:

package proxy;
import com.sap.ecm.api.AbstractCmisProxyServlet;
public class CMISProxyServlet extends AbstractCmisProxyServlet {
	private static final long serialVersionUID = 1L;

	@Override
	protected boolean supportAtomPubBinding() {
		return false;
	}

	@Override
	protected boolean supportBrowserBinding() {
		return true;
	}

    public CMISProxyServlet() {
        super();
    }

    @Override
    protected String getRepositoryUniqueName() {
        return "DocRep";
    }

    @Override
    // For applications in production, use a secure location to store the secret key.
    protected String getRepositoryKey() {
        return "1234567890abc";
    }

Hi Kirill,

Did you add the role EcmDeveloper to your user?

Best regards,

Hi ivan.mirisola , thanks for the answer. Added a role, now everything works.

But now I have another problem. I want use my ProxyBridge in XSJS app. I create .xshttpdest, but when I make a request, I have this problem, what could be wrong?

My .xshttpdest:

description = "Connection to Proxy Bridge App";
host = "https://cmisproxy******.hana.ondemand.com";
port = 443;
pathPrefix = "/cmisproxy/cmis/json";
proxyType = http;
proxyHost = "proxy";
proxyPort = 8080;
authType = basic;
useSSL = true;
timeout = 0;
sslAuth = anonymous;  

My xsjs code:

function getData() 
{
    try
    {
        var Dest = $.net.http.readDestination('********.******.xsjs.v01', 'documentservice');
        var Request = new $.web.WebRequest($.net.http.GET, '/cmisproxy/cmis/json');
        Request.headers.set("Authorization",'Basic ****************');
        var client = new $.net.http.Client();
    	client.request(Request, Dest); 
    	var response = client.getResponse();
    	var data = response.body.asString();
    	var parse_data = JSON.parse(data);
        return parse_data;
    }
    catch (e)
    {
        return e;
    }
}
getData();

Hi Kirill,

Perhaps you should thing of posting this doubt on a new question as it is a different issue now.

Regardless, I see here the error 400 - which could be something related to SSL handshake (missing certificate in the HANA trust store) or even that you have pathPrefix in both your destination and the request object itself.

Best regards,
Ivan
