Can I access to the reports repository via API?

I want to access the reports repository like the designer from my own client. How can I do it?

Since version 14.x the designer use a JSON-RPC API to access the remote repository. See the Wikipedia for details to JSON-RPC.
The same API is used in version 15.x and 16.x. There is no warranty that this will work in future versions. Currently there is no plan to change this in the future.

System requirments:

  • You need the plugins repository.zip and jsonrepository.zip in your server.
  • The user need the system permission rights for “Remote Designer” or “Repository”. The names can vary between different versions.

URL: <server base url>/jsonrpc/repository

Structures:

  • FolderDescription
  • String name
  • int rights
  • int foldertype
  • FileDescription
  • String name
  • long size
  • long lastModified
  • int rights

Methods:
All available methods of your version can be found in the enum com.inet.report.plugins.json.repository.shared.RepositoryMethods in the jsonrepository plugin.

The follow method documentation use a Java method declarartion like it will be used with a wrapper.

  • Root

FolderDescription = Root()

  • Folders
List<FolderDescription> = Folders(String parent)
  • Folder

FolderDescription = Folder(String parent, String name)

  • Files

List = Files(String parent)

  • File

FileDescription = File(String parent, String name)

  • CreateFolder

FolderDescription = CreateFolder(String parent, String name)

  • CreateFile

FileDescription = CreateFile(String parent, String name)

  • Rename

FileDescription/FolderDescription = Rename(String parent, String name)

  • Delete

Boolean = Delete(String element)

  • Exists

    Boolean = Exists(String element)

  • Thumbnail

ASCII-String = Thumbnail(String name)

  • Keywords

List = Keywords(String name)

  • SetKeywords

Boolean = SetKeywords(String name, String… keywords)

  • Search

List = Search(String phrase)

  • ServerVersion

String = ServerVersion()

  • Save

Boolean = Save(String name, ASCII-String data)

  • Load

ASCII-String = Load(String name)

Protocol Sample:

–> {“jsonrpc”: “2.0”, “method”: “Root”, “id”: 3}
<-- {“jsonrpc”: “2.0”, “result”: {“name”:“foo.rpt”,“rights”:0,“foldertype”:0}, “id”: 3}

Usage with JSON-RPC 2.0 library http://software.dzhuvinov.com/json-rpc-2.0-client.html

This library is very strict. You need the patched version 14.1.660 or higher.

Sample code:

import java.net.URL;

import com.thetransactioncompany.jsonrpc2.JSONRPC2Request;
import com.thetransactioncompany.jsonrpc2.JSONRPC2Response;
import com.thetransactioncompany.jsonrpc2.client.JSONRPC2Session;

public class JsonRpcTest {

public static void main( String[] args ) throws Exception {
    URL serverURL = new URL( "http://localhost:9000/jsonrpc/repository" );
    JSONRPC2Session session = new JSONRPC2Session( serverURL );
    JSONRPC2Request request = new JSONRPC2Request("Root", null);
    String[] contentTypes = {"application/binary-json", "application/error-json", "application/clearreport-json"};
    session.getOptions().setAllowedResponseContentTypes(contentTypes);
    JSONRPC2Response response = session.send(request);
    if (response.indicatesSuccess()) {
        System.out.println(response.getResult());
    } else {
        System.out.println(response.getError().getMessage());
        System.out.println(response.getError().getCode());
    }
}

}
