How to configure WSO2 ESB to route messages through a proxy server

When using WSO2 ESB, there are situations in which you need to talk to an endpoint which sits behind a proxy. In such cases, you should configure the ESB transport sender to forward the messages to the proxy server.
In order to do so, you just need to add the following two parameters as child elements of <transportSender name="http" class="org.apache.synapse.transport.nhttp.HttpCoreNIOSender">

<parameter name="http.proxyHost" locked="false">localhost</parameter>
<parameter name="http.proxyPort" locked="false">8090</parameter>

Note:- Change the proxy port and host according to your environment

Hello,

First of all, thanks for this information. I need to pass http proxy information to WSO2ESB because all connections should go through a proxy in our server. However, I am not sure how to supply this information (proxy host and port) in WSO2 ESB 4.7.0 for Windows. Do you have a walkthrough for that?

Thanks in advance.

WSO2 Stratos - Introducing WSO2 middleware Platform as a Service (PaaS)

Image
Yesterday we released our newest integrated cloud middleware platform, WSO2 Stratos . It is now online and ready for use! For the past few years, WSO2 has been doing many releases based on revolutionary Carbon platform , which helped to consistently improve the platform with introducing latest state-of-art technologies. The initial releases of Carbon product platform intended to improve the features of the individual products. For example, a lot of core features were introduced to WSO2 ESB, WSAS, Governance Registry etc.. Then we focused on ease of integration and more component based model. We introduced Equinox based provisioning model to build your SOA platform by picking and choosing the components as and when you need. Then, the core product platform has been enhanced to support multi-tenancy. With the multi-tenant supported architecture at hand, our brilliant development team was able to introduce the first ever comprehensive middleware PaaS. Why is this so important? Now, WSO2 C...

During the initial rounds of testing your integration solution or even in production systems, you may have come across the following error. org.apache.axis2.AxisFault: The system cannot infer the transport information from the URL .... Some of you may have struggled hours figuring out a solution to address this issue. Let me explain this error in detail and possible causes of this. So, next time when you see this error in your WSO2 ESB setup, you will not have to spend time unnecessarily googling everywhere. There can be many different causes of this error. I have observed  four main reasons. Cause 1 This is the simplest cause. Suppose, you have a proxy service similar to the following. <proxy xmlns="http://ws.apache.org/ns/synapse" name="MistakesTest...

Working with HTTP multipart requests in soapUI

Image
You can use HTTP request test step in soapUI to submit messages with various Content-Types.  In this post, we will have a quick look into the multipart/form-data requests in soapUI. multipart/form-data requests usually come into action when you do HTML form submissions with file attachments. For example, have a look at the following HTML form post. <form action="http://localhost:8090/CKFileUploadApp/UploadServlet" method="post" enctype="multipart/form-data"> <input type="file" name="file"> <input type="text" name="paramName"> <input type="submit" name="Submit" value="Upload File"> </form> In the forms like above, we have file upload option as a form input where we can upload a file along with the form submission. In that case, the request's HTTP content type will be multipart/form-data. How can we simulate such a request using soapUI...
