I have created the scaffolding for a dynamic task with a single added input/output value and it seems to work fine when I install it in ED and test it in a workflow. But, when I try to add the following code below, it installs but I get workflow errors that seem to be pointing to ClassNotFound type errors in the EngagementDesigner.log. My guess is that I'm either using the wrong objects to do an HTTP POST with Breeze, or missing some dependencies. Does anyone have an example of some code to do an HTTP POST in Breeze with the necessary Maven dependencies? Here is what I have. Note that this builds with "mvn clean package" fine and the svar loads/installs in ED, but I get an error when I use it in a workflow. The EngagementDesigner logs (with this code) are saying ClassNotFoundException for org.apache.http.ssl.SSLContext.


Code in my execute method of HelloExecution.java with simple HTTP POST to a test url (Open to a more Breeze-friendly code sample):

CloseableHttpClient httpclient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("http://testurl.com");
CloseableHttpResponse response2 = httpclient.execute(httpPost);
response2.close();

imports added to top of HelloExecution.java:

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.HttpRequest;

dependencies added to my pom.xml:

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-configuration2</artifactId>
<version>2.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.2</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.1</version>
<scope>compile</scope>
</dependency>

Import-Package setting in pom.xml (I keep adding classes to this each time I get ClassNotFound in the log and it fixes the one I added and gets another one. With this code, it is griping about org.apache.http.ssl.SSLContext, but if I add that to the Import-Package I get "Failed to Deploy" when I try to install the svar. So I'm not sure what's going on:

<Import-Package>org.apache.http.util,org.apache.http.protocol,org.apache.http,org.apache.http.config,org.apache.http.client.methods,org.apache.http.impl.client.*,com.avaya.collaboration.util.logger,javax.persistence,org.json,com.avaya.app.entity,com.avaya.workflow.*,com.roobroo.*;!*</Import-Package>

Roger,

Is there a way you can zip up your project and attach here? I can take a look at why it has runtime failures...

From what you are describing, it looks like there is some scope mix ups (compile VS provided) in one of the poms. Most likely the pom.xml that is sitting inside the "tasks" directory. Can you check if the class you are getting the ClassNotFound for while running has a "provided" scope in this pom? If it is, then it expects that class to be available at runtime - which is not.

Use compile scope and it will most likely work. But it may bloat up your deployment artifact (.svar) size.

Let me know. I can help. Thanks!

- Prakash.

I've attached the project directory, and yes it is the pom.xml in Tasks that I've been editing and I have used compile on all of them. Here are the only ones I've added. This project is getting an error when run in collaboratory about org.apache.http.ssl.SSLContext ClassNotFound. The typical way I've fixed those has been to add the base class (org.apache.http.ssl) to the <import-package> entry in the same pom.xml, but if I do that for this one I get a "failed to deploy" when I try to install it.

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-configuration2</artifactId>
<version>2.1</version>
<scope>compile</scope>

Please send all Collaboratory issues to collaboratory@avaya.com and mention what lab you are working in. Please let me know what lab you are working in.

I was told that I needed the 3.2 SDK, although there seems to be some confusion on your end which SDK(s) I need to update for 3.2. I have installed the 3.2 SDK on this link:

http://www.devconnectprogram.com/site/global/products_resources/avaya_breeze/avaya_snap_ins/engagement_designer/releases/3_2/index.gsp

I then created a new dynamic task project and it prompted me to use 3.2.
So I chose 3.2 and created the basic scaffolding project. Without
editing anything, I just ran "mvn clean package" and get this error. So I can't test my original issue until I get a raw 3.2 scaffolding project to build.

After installing the latest SDK, I still get the same error building a blank scaffolding project. Here is the entire log of what I did from command prompt:
