I was working on a project to call Oracle Data Integrator (ODI) from Oracle ESB as part of integration scenario. Part of the ODI installation is to set up infrastructure for public web services, that e.g. allows to call ODI integration scenarios remotely using Web Services calls. ODI Public Web Services uses Apache Axis2 as the web services container.
Installing Axis2 on OC4J 10.1.3. was a real "as easy as 1-2-3" task. Downloaded the WAR Distribution zip file from http://ws.apache.org/axis2/download.cgi, unzipped it on my hard disk and then deployed it using Oracle Application Server control.
After Axis2 WAR deployment, the web services container was ready to rock and to upload the odi-public-ws.aar file required by ODI.
This is just as a reminder for people that wonder how to work with Axis2 and OracleAS.
