Versions and osgi and async and such

[Benson Margulies]

I am struggling to maintain some code that wants to use the latest 4.x
version of http asynchronous client via OSGi.

The latest async client is 4.1.2. I've had this working, but a small change
has put me in a state where various things implode, so I'm trying to start
over from first principles.

When I use that as a dependency, I end up with ...

are you using the correct core version?

I wasn't. There's a servicemix OSGi jar that embeds an old copy of core
that snuck into the classpath.

Hi All ,

We are also trying to use the lastest HTTPClient 4.5.5 with Asycn Httpclient ..

When we try to bundle the latest Async HttpClient we are not able to start the application because of missing dependency.. we need to find the relevant OSGI jars httpclient-cache-4.5.3 etc which we could bundle

Can someone guide here ...

Thanks,
Aparma

You need to latest version of HttpCore 4.4.x OSGi bundle and HttpClient
4.5.x OSGi bundle.

Hi,

We tried and we are able to get our bundle up with the dependency of the httpclient async.. This is not an OSGI but via writing to the bundle classpath from pom.

<httpcore.version>4.4</httpcore.version>
<httpclient.version>4.5.4</httpclient.version>
<asyncclient.version>4.1.3</asyncclient.version>
<commons-logging.version>1.2</commons-logging.version>
<commons-io.version>2.4</commons-io.version>

<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpasyncclient</artifactId>
<version>${asyncclient.version}</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>

<dependency>

<version>${commons-logging.version}</version>
</dependency>
<dependency>


But when I run my service I'm getting

java.lang.NoSuchMethodError: org.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.<init>(Lorg/apache/http/impl/nio/reactor/IOReactorConfig;Ljava/util/concurrent/ThreadFactory;)V
org.apache.http.impl.nio.client.IOReactorUtils.create(IOReactorUtils.java:43)
org.apache.http.impl.nio.client.HttpAsyncClientBuilder.build(HttpAsyncClientBuilder.java:666)
org.apache.http.impl.nio.client.HttpAsyncClients.createDefault(HttpAsyncClients.java:60)

I tried moving to the different version of httpcore.. It still does not work.

Can some please help here

There still must be an older version of HttpCore on your classpath.
