Subject [jira] [Commented] (AIRAVATA-1635) [GSoC] Integrate Airavata Java Client SDK with GridChem Client
Date Thu, 19 Mar 2015 01:26:38 GMT


Dimuthu Upeksha commented on AIRAVATA-1635:

Hi all,

Suresh : Ok. I removed previous forks in my repo and these are new forks

I will be working on my forks until I improve builds. Hopefully we may be able to convert
ant builds to maven builds. Then I'll send you a pull request. 

I tried to run GridChem-2.0.0.jar  using java -jar GridChem-2.0.0.jar but it gave following
error. How can I resolve this? It seems like some libraries are not added to the classpath.

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/CommandLineParser

Sudhakar: Thank you. I'll look into that and let you know in case of issue. 

I may need some details of how to build and start GridChem-Middleware-Service. I can see some
targets in build.xml but couldn't figure out which target to invoke. There are some shell
scripts inside the project (,,,,, What is the correct script(s) that are needed to start the server?

> GridChem is a Science Gateway enables users to run computational experiments on multiple
supercomputing resources. Currently GridChem, a java swing based webstart client [1] uses
a Axis2 based Middleware Service [2] which brokers users actions into computational jobs.

> This project needs to understand the Client [1] and port it to use Apache Airavata java
client SDK. The project has following components:
> * Integrate GridChem client with Airavata User Store (implemented by WSO2 Identity Server)
> * Integrate with Airavata API for application executions.
> * Integrate with Atlassian JIRA + Confluence for user error reporting and status notifications.
