SAP CAP Java connection to OnPremise destination service is throwing error

2024-02-01T01:40:55.638000+01:00

Hi Experts,

I am trying to connect On Premise ( SAGE Api system ) through my Java CAP application.

I am using DestinationAccessor to connect my destination, I made successful connection to destination, but I couldn't read the content from API system.

This is my code.

HttpDestination destination = DestinationAccessor.getDestination(destName).asHttp();

HttpClient client = HttpClientAccessor.getHttpClient(destConfiguration);

HttpGet request = new HttpGet(absoluteURI);

HttpResponse response = client.execute(request);

My absolute URI is "http://devsage:9999/portalapi/api/data/Orders" , the same url is working when I tried,

"curl -v -i "dest_name.dest/portalapi/api/data/Orders" and it is giving data.

client.execute is giving below error, in my BAS,

I/O exception (java.net.SocketException) caught when processing request to {}->http://connectivityproxy.internal.cf.ap10.hana.ondemand.com:20003->http://devsage:9999: Connection reset

This is my destination created in BTP.

Thanks in advance,

Ramkumar

SAP CAP JAVA accessing business rules destination is giving bad credentials error

2024-02-01T03:26:30.632000+01:00

Hi Experts,

I am trying to access Business rule destination defined in BTP through DestinationAccessor but it is giving below error,

"Failed to read authentication token of destination 'BUSINESS_RULES_BPA'. The destination service responded with an error: 'Bad credentials'.

This is my code to access the destination,

DestinationAccessor.getDestination("BUSINESS_RULES_BPA").asHttp()

The same client secret and password is working fine in Postman.

Thanks in advance.

How to use Cloud SDK OpenAPI Client with CAP?

2024-02-23T06:19:37.594000+01:00

Hi community,

I'm attempting to use the Cloud SDK's OpenAPI Client in a CAP Java project, but I'm unable to access the generated API client. The structure of my project is as follows:

The OpenAPI Client has been generated with the following setting in pom.xml.

			<plugin>
				<groupId>com.sap.cloud.sdk.datamodel</groupId>
				<artifactId>openapi-generator-maven-plugin</artifactId>
				<version>${cloud.sdk.version}</version>
				<executions>
					<execution>
						<goals>
							<goal>generate</goal>
						</goals>
						<phase>generate-sources</phase>
					</execution>
				</executions>
				<configuration>
					<inputSpec>${project.basedir}/api-specs/AuthorizationAPI.yaml</inputSpec>
					<outputDirectory>${project.basedir}/openapi</outputDirectory>
					<apiPackage>customer.cap_openapi.generated.authorization.api</apiPackage>
					<modelPackage>customer.cap_openapi.generated.authorization.model</modelPackage>
					<apiMaturity>released</apiMaturity>
				</configuration>
			</plugin>

Here's the source for the CAP event handler:

package customer.cap_openapi.handlers;

import org.springframework.stereotype.Component;

import com.sap.cds.services.handler.annotations.On;
import com.sap.cds.services.handler.annotations.ServiceName;
import com.sap.cloud.sdk.cloudplatform.connectivity.DestinationAccessor;
import com.sap.cloud.sdk.cloudplatform.connectivity.HttpDestination;

import customer.cap_openapi.generated.authorization.api.RoleCollectionsApi;
import cds.gen.authorizationservice.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Component
@ServiceName(AuthorizationService_.CDS_NAME)
class AuthorizationServiceHandler {

    Logger logger = LoggerFactory.getLogger(AuthorizationServiceHandler.class);
    
    @On(event = GetRoleCollectionsContext.CDS_NAME)
    public void getRoleCollections(GetRoleCollectionsContext context) {
        logger.info("getRoleCollection handler");

        HttpDestination destination = DestinationAccessor.getDestination("xsuaa").asHttp();
        // RoleCollectionsApi rolecollectionApi = new RoleCollectionsApi(destination);
        
    }
}

I'm encountering the error "The import customer.cap_openapi.generated cannot be resolved". Is the srv/openapi directory the appropriate place to generate the OpenAPI Client? How can I make the Open API client accessible from the event handler source?

The code for the project is available in the following Git repository: https://github.com/miyasuta/cap-openapi/tree/generate_client

Filter Attachments displayed on Customer BO

2024-03-16T00:03:40.081000+01:00

Hi,

I'm trying to create 3 EC to display Attachments linked to Customers (BO); these 3 EC would be filtered according to TypeCode (standard and custom ones), however, it seems it doesn't work properly.

I have followed the last part of this article "Display selected Documents in Front End" (https://community.sap.com/t5/enterprise-resource-planning-blogs-by-members/selected-document-type/ba-p/13329469), it works for a custom BO, but not for an EC of Attachments based on Customer standard BO, all attachments keep on displaying.

Here it the reuse COD_Documentlist:

The binding is correct:

Worse, is the AdvancedListPane for DocumentList (Customer.Root.AttachmentFolder.DocumentList), everything is bind correctly, but somehow, CategoryType and TypeCode values just don't display in the list...

Even if the value is actually there, in the 2nd line in "Type de document" (TypeCode) column...

The DataModel:

Is the entity Attachments untouchable? What is SAP hiding??

How to call API endpoint on BTP nodejs app from another BTP app?

2024-03-21T15:46:00.486000+01:00

Hi all,

I have a BTP NodeJS application (A) which needs to make a REST call to another BTP application (B) at a regular interval.

In the mta.yaml file for app (A) I have specified the following resource which links to the exposed service of app (B):

  - name: app_a_using_app_b_api
    type: configuration
    parameters:
      provider-nid: mta
      provider-id: <app B name>:<app B exposed service>
      version: ">=0.0.0"

This resource has been added as a required resource for app (A) module:

  - name: app_a_srv
    type: nodejs
    path: .
    requires:
      - name: app_a_db
      - name: app_a_using_app_b_api
        group: destinations       
        properties:
          forwardAuthToken: false
          name: app_b_api
          url: ~{url}         
          timeout: 30000

In app (A) package.json I then specified the destination:

  "cds": {
    "requires": {
      "middlewares": true,
      "app_b_api": {
        "kind": "destination",
        "credentials": {
          "destination": "app_b_api"
        }
      }
    }
  }

Within app (A), at a regular interval, the following function is then called:

    async doRequestToAppB() {
        try {
            const destination = await getDestination({ destinationName: "app_b_api" });
            const data = await executeHttpRequest(destination, {
                method: 'GET',
                url: "/api/ping"
            });

            logger.info(`Request OK: ${JSON.stringify(data)}`);
        } catch (err) {
            logger.error(`Request FAILED: ${err}`);
        }
    }

This request now fails with the following error in the catch-clause:

[app_a] - Request FAILED: TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'TLSSocket'
    | property '_httpMessage' -> object with constructor 'ClientRequest'
    --- property 'socket' closes the circle

I have tried many ways, but somehow I don't seem to be able to have app (A) automatically do a request to app (B), failing with the above error...

I also tried to debug the executeHttpRequest function from within BAS, but that did not give me any clues either.

If anyone has any clues, ideas, directions or tips on how to solve this, that will be highly appreciated!

Thanks in advance,

CAP Java - Destination - Proxy Configuration

2024-04-08T14:22:09.604000+02:00

Hello Community,

we are developing a Java CAP application on the BTP and need to access data from an on-premise system.

The cloud connector is configured and the destination created in the cockpit.

We are able to use curl in the Business Application Studio terminal and use the destination.

We followed the documentation to access remote services in Java CAP and create a HTTP client.

import com.sap.cloud.sdk.cloudplatform.connectivity.Destination;
import com.sap.cloud.sdk.cloudplatform.connectivity.DestinationAccessor;
import com.sap.cloud.sdk.cloudplatform.connectivity.HttpClientAccessor;
import org.apache.http.client.HttpClient;

Destination destination = DestinationAccessor.getDestination("toKbvStage");
HttpClient client = HttpClientAccessor.getHttpClient(destination);

On the BAS we export some configuration and are then able to use the HTTP client.

export destinations='[ { "type": "HTTP", "name": "toKbvStage", "url": "http://toKbvStage.dest", "ProxyHost": "localhost", "ProxyPort": 8887 } ]'

In the mta.yaml we bind the destination service to our service. In the log file we receive the following error:

Unable to create an HttpClient from the provided destination. The destination is supposed to target an on-premise system but lacks the correct proxy configuration. Please check the application logs for further details.

My interpretation of the error is, that the destination is found, but something on the destination configuration is missing. Does anybody know, how to solve this? Am I missing any additional configuration?

CAP odata-v2-adapter: batch request is not supported?

2024-04-25T23:26:14.891000+02:00

Hi community,

I have developed an OData service with CAP using odata-v2-adapter. When I try to execute $batch requests to the v2 endpoint, the service returns the following error:

{
    "error": {
        "code": "400",
        "message": {
            "lang": "en",
            "value": "OData-Version '2.0' is not a supported version."
        },
        "severity": "error",
        "target": "/#TRANSIENT#",
        "ContentID": "cov2ap_1",
        "innererror": {
            "errordetails": [
                {
                    "code": "400",
                    "message": {
                        "lang": "en",
                        "value": "OData-Version '2.0' is not a supported version."
                    },
                    "severity": "error",
                    "target": "/#TRANSIENT#",
                    "ContentID": "cov2ap_1"
                }
            ]
        }
    }
}

In the request body, odata-version: 2.0 is specified.

request url: /odata/v2/sales/$batch

--batch
Content-TYpe: multipart/mixed; boundary=changeset

--changeset
Content-Type: application/http
Content-Transfer-Encoding: binary

POST SalesOrders HTTP/1.1
Content-Type: application/json
odata-version: 2.0

{
    "orderDate": "2024-04-23",
    "customer": "Postman",
    "items": [
        {
            "product": "PC",
            "quantity": 1,
            "price": 1000
        }
    ]
}

--changeset--

--batch--

The error is raised at the following line of code.

If I remove the "odata-version: 2.0" or change the version to 4.0 (inconsistent with the request url though), the request succeeds. This makes calling the v2 endpoint using SAP Cloud SDK (Java) OData v2 client difficult, as the client (seemingly) sets "odata-version: 2.0".

Is there any solution for this issue?

Assistance Required: SMTP Authentication Error in BTP CAP Application

        try
        {
            const mailConfig = {
              from: 'test@gmail.com',
              to: 'test@gmail.com',
              subject: 'e-mail subject',
              text: 'e-mail text'
            };
            sendMail({ destinationName: 'hotmail' }, [mailConfig]);
            return data;
        }
        catch(err) {
            console.log(err);
        }
    });

Thank you in advance for your help!

Adding connectivity-destination-service as a dependency makes the CAP service endpoints disappear

2024-05-01T23:40:55.051000+02:00

Hi community,

In a CAP application developed with Java, I am trying to use SAP Cloud SDK (Java) to make batch request to a remote OData service. Local testing works fine. Now, to deploy this application to Cloud Foundry, I've added the following dependency to the srv/pom.xml, as per the document. Cloud SDK version is 5.8.0.

		<dependency>
			<groupId>com.sap.cloud.sdk.cloudplatform</groupId>
			<artifactId>connectivity-destination-service</artifactId>

Then, strangely, all the service endpoints are disappeared.

Have any of you experienced such issue?

SAP CAP - Could not work with on-premise remote odata service via destination - 401 authentication

2024-05-13T09:13:13.054000+02:00

Hi all,

I have a CAP framework based application which is intended to connect to a remote service via destination (on-premise odata v2 service).

The name of the destination is MyDest1.

The contents of the package.json are as below:

          }
        },
        "[production]": {

my-service.js:

const cds = require('@sap/cds');
module.exports = cds.service.impl(async function() {
    const bupa = await cds.connect.to('ZGW_MY_SRV');
  
    this.on('READ', ['EntityA', 'EntityB'], async (req) => {
        try {
            const result = await bupa.run(req.query);
            return result
        } catch(error) {
            console.error("Error accessing destination:", error);
            // throw new Error("Failed to access data from destination.");
            req.error(502, `Gateway error: ${error.message}`);
        }
    });
});

If I run the application in Business Application Studio (BAS) using commands:

cf login -a https://api.cf.eu10.hana.ondemand.com/ --sso and cds watch --profile hybrid,

it works as in if I click on the entity from the previewed services in the new tab, I get the data from the on premise system via destination and the same gets logged to the BAS terminal:

[2024-05-11T10:48:58.004Z] INFO     (env-destination-accessor): Successfully retrieved destination 'MyDest1' from environment variable.

However once deployment to the BTP cloud foundry space, it throws an error message as 401 Unauthorized.

In the apps that I access via cf logs <myapp-srv> --recent, I could see the URL I am maintaining in the destination in axios error logs.

I believe the CAP library is able to get the URL but not performing the authentication based on the method, username and password provided in the destination.

Need help.
