Hi,

1. Can you check that the generated MANIFEST contains the afterburner import ?
2. If you install afterburner bundle after your bundle, you have to refresh your bundle as it's an optional import

Hi,

I have a simple Hello World type Karaf Bundle. The activator code looks
like below:-

|public class HelloWorldActivator implements BundleActivator { @Override
public void start(BundleContext bundleContext) throws Exception {
System.out.println("STARTING DEMO: hello, world\n");
System.out.println(getJsonDataAsString()); } @Override public void
stop(BundleContext bundleContext) throws Exception {
System.out.println("STOPPING DEMO"); } private String
getJsonDataAsString() { JsonDataBlob jsonDataBlob = new JsonDataBlob();
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new AfterburnerModule()); try { return
objectMapper.writeValueAsString(jsonDataBlob); } catch(Exception e) {
e.printStackTrace(); } return ""; } } |

The java object which I am trying to convert to json is a simple object
as shown below:-

|package com.hello.world; public class JsonDataBlob { private String add1
= "JP Naagar"; private String add2 = ""; private int shippartagent = 1;
public String getAdd1() { return add1; } public void setAdd1(String
add1) { this.add1 = add1; } public String getAdd2() { return add2; }
public void setAdd2(String add2) { this.add2 = add2; } public int
getShippartagent() { return shippartagent; } public void
setShippartagent(int shippartagent) { this.shippartagent =
shippartagent; } } |

Whenever I am trying to install the bundle I am getting the below
exception:-

All the required Jackson bundles are installed in Karaf:-

|karaf@root>bundle:list | grep Jackson 123 | Active | 50 | 2.6.2 |
Jackson-core 125 | Active | 50 | 2.6.2 | Jackson-annotations 238 |
Installed | 80 | 2.7.1 | Jackson-module-Afterburner
karaf@root>bundle:list | grep jackson 124 | Active | 50 | 2.6.2 |
jackson-databind |

Everything works fine if I just comment out the below line:-

|objectMapper.registerModule(new AfterburnerModule()); |

I have placed the required code in github
<https://github.com/debraj-manna/afterburner-issue>

Has anyone able to execute the Jackson's Afterburner module in Karaf 3.0.5?

Thanks,

Debraj
