we are using
import org.opensaml.saml2.metadata.provider.AbstractObservableMetadataProvider;
import org.opensaml.saml2.metadata.provider.MetadataProviderException;
in opensaml 2. however now i want to upgrade it to opensaml 3. are there any alternatives for AbstractObservableMetadataProvider and MetadataProviderException in opensaml 3?

I'm parsing a XML string to convert it to a JsonNode in Scala using a XmlMapper from the Jackson library. I code on a Databricks notebook, so compilation is done on a cloud cluster. When compiling my code I got this error java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; with a hundred lines of "at com.databricks. ..."
I maybe forget to import something but for me this is ok (tell me if I'm wrong) :
import ch.qos.logback.classic._
import com.typesafe.scalalogging._
import com.fasterxml.jackson._
import com.fasterxml.jackson.core._
import com.fasterxml.jackson.databind.{ObjectMapper, JsonNode}
import com.fasterxml.jackson.dataformat.xml._
import com.fasterxml.jackson.module.scala._
import com.fasterxml.jackson.module.scala.experimental.ScalaObjectMapper
import java.io._
import java.time.Instant
import java.util.concurrent.TimeUnit
import javax.xml.parsers._
import okhttp3.{Headers, OkHttpClient, Request, Response, RequestBody, FormBody}
import okhttp3.OkHttpClient.Builder._
import org.apache.spark._
import org.xml.sax._
As I'm using Databricks, there's no SBT file for dependencies. Instead I installed the libs I need directly on the cluster. Here are the ones I'm using :
com.squareup.okhttp:okhttp:2.7.5
com.squareup.okhttp3:okhttp:4.9.0
com.squareup.okhttp3:okhttp:3.14.9
org.scala-lang.modules:scala-swing_3:3.0.0
ch.qos.logback:logback-classic:1.2.6
com.typesafe:scalalogging-slf4j_2.10:1.1.0
cc.spray.json:spray-json_2.9.1:1.0.1
com.fasterxml.jackson.module:jackson-module-scala_3:2.13.0
javax.xml.parsers:jaxp-api:1.4.5
org.xml.sax:2.0.1
The code causing the error is simply (coming from here : https://www.baeldung.com/jackson-convert-xml-json Chapter 5):
val xmlMapper: XmlMapper = new XmlMapper()
val jsonNode: JsonNode = xmlMapper.readTree(responseBody.getBytes())
with responseBody being a String containing a XML document (I previously checked the integrity of the XML). When removing those two lines the code is working fine.
I've read tons of articles or forums but I can't figure out what's causing my issue. Can someone please help me ? Thanks a lot ! :)
Welcome to dependency hell and breaking changes in libraries.
This usually happens, when various lib bring in different version of same lib. In this case it is Jackson.
java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; means: One lib probably require Jackson version, which has this method, but on class path is version, which does not yet have this funcion or got removed bcs was deprecated or renamed.
In case like this is good to print dependency tree and check version of Jackson required in libs. And if possible use newer versions of requid libs.
Solution: use libs, which use compatible versions of Jackson lib. No other shortcut possible.
upgrading to 2.12.5 version fixed my issue.
this issue may also appear when there are multiple versions of jackson jars in project lib directory. you should remove the older versions.
I have a lot of successful rest accesses in grails 2.x.x
I simply coded
import grails.plugins.rest.client.*
import grails.util.Holders
import org.codehaus.groovy.grails.web.json.JSONObject
import org.codehaus.groovy.grails.web.json.JSONArray
and Classes JSONObject, JSONArray, RestBuilder, RestResponse where available for further use.
What are the corresponding imports in 4.0.1 and what jars resp. what lines in build.gradle are necessary?

Grails 4 offers better options than to interact with the classes you asked about but to answer the question as asked...
org.grails.web.json.JSONObject is in grails-web-common-4.0.1.jar. Use import org.grails.web.json.JSONObject.
org.grails.web.json.JSONArray is in grails-web-common-4.0.1.jar. Use import org.grails.web.json.JSONArray.
grails.plugins.rest.client.RestBuilder is in grails-datastore-rest-client-6.1.12.RELEASE.jar. Use import grails.plugins.rest.client.RestBuilder.
grails.plugins.rest.client.RestResponse is in grails-datastore-rest-client-6.1.12.RELEASE.jar. Use import grails.plugins.rest.client.RestResponse.
Depending on what other dependencies you may have in your project those may or may not be pulled in transitively so you may not need to add them to your build.gradle directly. The most likely scenario is you won't need to add anything to pull in grails-web-common-4.0.1.jar but you probably will need to pull in grails-datastore-rest-client-6.1.12.RELEASE.jar which can be done by adding the following to your build.gradle:
compile "org.grails:grails-datastore-rest-client:6.1.12.RELEASE"
If you want to pull in grails-web-common explicitly you could use the following:
compile "org.grails:grails-web-common:4.0.1"
If you are using the BOM correctly, you could simplify that with the following:
compile "org.grails:grails-web-common"
I hope that helps.
In the c++ environment, I can use the cvEigenVV command, but I import the opencv module in python, corresponding to which API ?
the error in python: module 'cv2' has no attribute 'cvEigenVV'
I am developing Spring Boot + AXON example from the link: https://blog.novatec-gmbh.de/event-sourcing-spring-boot-axon/ and just updated Spring Boot version 2.1.0.RELEASE.
Multiple markers at this line
- The type DefaultMongoTemplate is deprecated
- The constructor DefaultMongoTemplate(MongoClient) is
deprecated
Code
import com.mongodb.MongoClient;
import org.axonframework.eventsourcing.eventstore.EventStorageEngine;
import org.axonframework.mongo.eventsourcing.eventstore.DefaultMongoTemplate;
import org.axonframework.mongo.eventsourcing.eventstore.MongoEventStorageEngine;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
#Configuration
public class AggregateConfig {
#Bean
public EventStorageEngine eventStore(MongoClient client) {
return new MongoEventStorageEngine(new DefaultMongoTemplate(client));
}
}
Looks like DefaultMongoTemplate code is deprecated, what's the replacement for it ?
As off Axon release 4.0, extension package, like Mongo, have been moved to a dedicated repository (which you can find here). Additionally, when upgraded from Axon 3.x to 4.0, we have replaced several constructors on the infrastructure components in favor of the Builder pattern.
One of these which has undergone that change, is the DefaultMongoTemplate.
A part from that story though, I just checked out Axon 3.x (as I assume you're not looking at 4.0 at the moment), and the org.axonframework.mongo.eventhandling.saga.repository.DefaultMongoTemplate is deprecated in favor of the org.axonframework.mongo.DefaultMongoTemplate. I pull this from the javadoc at the moment, so I had hoped that would be visible on your side.
Any how, I hope this helps you out!
And if you've got the change, I'd recommend to upgrade to Axon 4.x, as new features will get added in that version instead of version 3.x.
I am using OpenWhisk on Bluemix . I need to make the following in order to redirect std streams:
from IPython.utils.io import capture_output
I encounter an error
ImportError: No module named IPython.utils.io
Is there a solution there for missing modules?
