Create a new asset in Guvnor through REST API (POST method)

neokiing Jan 28, 2013 12:29 AM

Hi All,

I am trying to create an asset (.txt file ) in GUVNOR through REST API in JAVA. But the problem is when using the post method to create asset .. program is executing with no error but i am having SERVER_ERROR(http 500 error..) as a response.

Steps I followed :-

1.Created an asset named SayanFileTest

2.Got the Asset Info in Atom -XML format ..

3.Replaced the asset name With new one (FileUploadTest1)

4.Called the post method to create a new entry in GUVNOR.

Can anybody please help me with this one? I am providing the code.. Please tell me what i am doing wrong in this and how to solve it.

(N.B. - I am using jboss-as-7.1.1.Final and drools-guvnor 5.3.0)

***********************

//package imported..

import org.apache.abdera.model.Document;

import org.apache.abdera.model.Entry;

import org.apache.abdera.protocol.Response.ResponseType;

import org.apache.abdera.protocol.client.AbderaClient;

import org.apache.abdera.protocol.client.ClientResponse;

import org.apache.abdera.protocol.client.RequestOptions;

// Post method

Abdera abdera= new Abdera();

AbderaClient client = new AbderaClient(abdera);

UsernamePasswordCredentials userpass = new UsernamePasswordCredentials("admin","admin");

client.addCredentials(url.toExternalForm(),null,"Basic",userpass);

ClientResponse resp = client.get(new URL("http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/SayanFileTest").toExternalForm());

Document<Entry> doc = resp.getDocument();

Entry prevEntry = doc.getRoot(); // have done this to get the atom-entry at the first place

Entry newEntry = abdera.newEntry();

// copied the prevEntry to populate the below string

String newResponse ="<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><atom:entry xmlns:atom=\"http://www.w3.org/2005/Atom\" xmlns=\"http://www.w3.org/XML/1998/namespace\" xml:base=\"http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/SayanFileTest\"><atom:title xmlns:atom=\"http://www.w3.org/2005/Atom\" type=\"text\">SayanFileTest</atom:title><atom:id xmlns:atom=\"http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/SayanFileTesthttp://www.w3.org/2005/Atom\">http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/SayanFileTest</atom:id><atom:published xmlns:atom=\"2013-01-23T14:10:33.173+05:30http://www.w3.org/2005/Atom\">2013-01-23T14:10:33.173+05:30</atom:published><atom:author xmlns:atom=\"http://www.w3.org/2005/Atom\"><atom:name xmlns:atom=\"adminhttp://www.w3.org/2005/Atom\">admin</atom:name></atom:author><atom:content xmlns:atom=\"http://www.w3.org/2005/Atom\" type=\"application/octet-stream\" src=\"http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/SayanFileTest/binary\"></atom:content><atom:summary xmlns:atom=\"http://www.w3.org/2005/Atom\" type=\"text\"></atom:summary><metadata xmlns=\"\"><uuid><value></value></uuid><categories></categories><format><value>.txt</value></format><state><value>Draft</value></state><versionNumber><value>2</value></versionNumber><checkinComment><value></value></checkinComment><archived><value>false</value></archived></metadata></atom:entry>";

// replaced the name of the previous asset

newResponse=newResponse.replaceAll("SayanFileTest","FileUploadTest1");

System.out.println(newResponse);

newEntry.setContent(newResponse);

        client = new AbderaClient(abdera);
        client.addCredentials(new URL("http://localhost:8080/drools-guvnor/").toExternalForm(), null,"Basic",new org.apache.commons.httpclient.UsernamePasswordCredentials("admin", "admin"));

        RequestOptions options = client.getDefaultRequestOptions();
        options.setContentType(MediaType.APPLICATION_ATOM_XML);

        ClientResponse clientResponsePost = client.post(new URL("http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets").toExternalForm(), newEntry, options);

        System.out.println(clientResponsePost.getType()+ "__________ " + clientResponsePost.getStatus());

I am a newbie in this. Any help will be really appreciated.

Thanks in advance ,

Hi.

You can try running this method.

private static void addingNewAsset() {
        WebClient client = WebClient.create("http://localhost:8080");
        byte[] fileBytes = null;
        try {
            fileBytes = Files
                    .readAllBytes(Paths
                            .get("src/main/resources/com/resources/guvnor/assets/guvnorRuleExample.drl"));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        String fileSource = new String(fileBytes);
        Response response = client
                .path("guvnor/rest/packages/testPackage/assets")
                .accept(MediaType.APPLICATION_ATOM_XML_TYPE)
                .header(AUTHORIZATION, AUTHORIZATION_VALUE)
                .type(MediaType.APPLICATION_OCTET_STREAM_TYPE)
                .header("slug", "guvnorRuleExample.drl").post(fileSource);
        System.out.println("Status:" + response.getStatus());
    }

* You should have running guvnor in local instance (localhost:8080/guvnor)
* you should have a package called "testPackage"

Cheers
