Load Test SSE Services with JMeter help

Hi,

 I am trying to load test sse services with JMETER via java sampler. My java class works fine and connects to stream. but when i try to export java program to jar and then use that jar in jmeter as java sampler, it gives me classnot found error. can you please help me with this? I am attaching the java project and jmeter project with this query

How to run Java Project:

1. Open Project in eclipse

2. add all libraries inside ./extJar as external jars to project build path

3. Run Main method in AppTest class (this will show that the stream is being read by logic)

Here are the steps i followed.

1. Created a java project and imported two external jars from jmeter install directory

a. ApacheJMeter_core.jar

b. ApacheJMeter_java.jar

2. Created java sampler class in eclipse extending AbstractJavaSamplerClient

3. Created some other logic for SSE events handling. All the external libraries required for this are kept in ./extJar folder

4. Exported the project into Jar

5. Placed this Jar into lib/ext folder of jmeter 

6. Created a jmeter project and used java sampler

7. chose the class the dropdown

8. Run the test.

Observations: observed following error
