[Isuru Udana]

Hi Venkat,

You should be able to build the product without an issue in the following
order.

1. https://github.com/wso2/carbon-transports
2. https://github.com/isudana/carbon-gateway
3. https://github.com/isudana/product-integration-server

Thanks.

 Hi Senduran,

 I've tried your samples and they are working fine.  Now I'm pretty
 comfortable with messaging internals.

 Since I am able to get response back from BE server, I thought of
 starting off by defining custom XML XSD's.  I'm using JAXB for reading XML
 objects.  When I run it as a standalone program, it is working fine.  But,
 when I run it within OSGi, I'm getting exception.

  I tried all possible solutions given here
 .


 Kindly find the project here
 .

 Could you kindly help me with this.?  Is it advisable to use JAXB with
 OSGi..?

 Meanwhile I'll try other ways also.

 Hi Venkat,

 As a first step, you can extend the carbon message process with your
 simpleLB. Similar to your MockEngine.
 I'll share you a sample soon to send a request to the server.

 Hi Isuru,

 Thank you.

 I went through the code and I'm having good overview about it.  I
 also tried connecting to gateway through TELNET and tried few OSGi
 commands.  It worked fine.

 I tried implementing the same MockEngine Example
 ,
 but I'm getting this Error 

 Please find the code here:

 MockEngine.java

Re: [Dev] Proposal 8: [ESB/GW] HTTP Load balancer on top of WSO2 Gateway - Reg

[Kasun Indrasiri]

I think for the LB runtime also we should use the same engine that we are
building for the integration server. I think IsuruU is still finalizing the
code and the repo structure. Once it is completed, Venkat can start working
on the same engine.
So, in the mean time shall we start focusing on a use case. May be the
session persistence thing?

Hi Venkat,

I have gone through your usecases document and it seems good.We need to
figure out a way how we can actually implement those usecases. As Kasun
mentioned please look in to carbon transport implementation and try to
write a simple engine . Basically we need figure out best way for configure
transport according to configurations given through engine . for  example
we need to configure transport for SSL support and those informations are
published by loadbalancer  engine to the transport any how those need to be
loosely couple with transport implementation .

thanks

Re: [Dev] Proposal 8: [ESB/GW] HTTP Load balancer on top of WSO2 Gateway - Reg

[Kasun Indrasiri]

Hi Venkat,

May be you should start going through the carbon http transport and GW
code[1]. Please not that we won't be using Camel as the message routing
engine for the loadbalancer as it too heavy weight. I think,
understanding[2] about OSGI and how carbon transport/messaging/engine works
together is important at this point.

Hi Venkat,

Thanks for the great enthusiasm.  We will look in to that and let you  know
soon.

 Hi Isuru,

 Thank you this document helped me to understand requirements of this
 Proposal in a much clear way.

 Yesterday I downloaded Beta3 release of product-gw and tried header
 based and REST based mediation. And I also started learning about Apache
 Camel. I also noticed Netty logs while starting gateway.

 I could understand how product-gw will work and the degree of
 customization it provides.

 I also did research on HTTP LBs and read about Google App Engine LB in
 detail.

 Yes, sure. I'll do these background work

 It would be helpful if you could provide me  detailed Architecture
 Diagrams for Carbon Messaging, Carbon Transports and Product Gateway also.

 Thanks,
 Venkat.

 Hi Isuru & Kasun,

 I am Venkatraman, pursuing Final year B.Tech Computer Science &

 area of
 interest is Computer Networking and I am also proficient in JAVA
 programming.

 I came to know about WSO2 through its contribution in GSOC 2015 and
 I'm very eager & excited to work on WSO2 products.

 The other proposals involving WSO2 gateway have
 https://github.com/wso2/product-gw as reference URL. But in
 Proposal 8 no refgerence URL is mentioned.

 Could you kindly guide me in starting with this proposal idea?

 Will be looking forward to hear from you.

Hi Venkat,

Thanks for your interest in the above proposal. Yes, the same link is valid
for all the projects related GW (I've updated the references). So, to get
started with you can start running the samples and going through the code
base of GW.
Also you can come up with the use cases that you are planning to add on top
of HTTP GW. And come up with a design of the existing GW and how the LB
related features will be implemented on the GW.

Please subscribe to dev@wso2.org and use that mailing list to communicate
