Installing BAM Mediator Feature
The following installation instructions apply to WSO2 ESB version 1. Download WSO2 ESB version 4.5.x onwards.1. Download the WSO2 ESB from location: or later from http://wso2.com/products/enterprise-service-bus. Since BAM Mediator Aggregate feature is available by default from ESB 4.6.0 onwards, you do not have to install it separately if you use a newer ESB version.
2. Since both ESB and BAM server will be run concurrently, change the port number of ESB by applying an offset. To apply an offset, navigate to <ESB_HOME>/repository/conf and open file, carbon.xml, where <ESB_HOME> is the WSO2 ESB's product distribution directory. Then change the value in xpath Server/Ports/Offset from 0 to some other integer. For example,
...
- As the ESB pack was downloaded and started, downloaded and start the WSO2 BAM without the same port offset as ESB.
- In the ESB product directory go to $esb_home/samples/axis2Client
- Build the backend service with Apache Ant (You need to install Apache Ant before that.) with the following code.
ant stockquote -Daddurl=https://localhost:8244/services/Simple_Stock_Quote_Service_Proxy -Dmode=fullquote -Dsymbol=testString
(Here addurl value should be given from the https endpoint located in Simple_Stock_Quote_Service_Proxy's service dashboard that can be navigated by going to the ESB management console Main→Web Services→List Main→Services→List from side panel and selecting Simple_Stock_Quote_Service_Proxy. Any preferred string can be used instead of the testString for symbol )
Now BAM mediator in the proxy service, Simple_Stock_Quote_Service_Proxy should have dumped data extracted from the ESB to the key-space, EVENT_KS in the Cassandra database, with column family name same as the Stream Name. Data in the Cassandra database can be seen from the Cassandra Explorer in the BAM server.
