Dear all, For info: I am new to Jenkins... just started to use it last month. Trial 1: I have installed jenkins on a windows server, installed TFS plugin and the connection to TFS is successful. Trial 2: I have installed Jenkins on AIX... I placed the Jenkins.war file in the webapps folder in tomcat and started tomcat. Jenkins was deployed and when launching the job (Build now) I got the same error as you described above. Trial 3: I have installed Jenkins on Redhat... I placed the Jenkins.war file in the webapps folder in tomcat and started tomcat. Jenkins was deployed, i installed the TFS plugin and when launching the job (Build now) I got the same error as you described above Trial 4: I installed Jenkins on Linux without using tomcat. I got the rpm file from http://pkg.jenkins-ci.org/redhat/ and installed it using yum. I installed the TFS plugin and it works perfectly. The problem is that I must have Jenkins installed on AIX. Again I am new to Jenkins but I am not sure the it has to do with the server URL. Hope the above can guide the experts to a solution. Didier M |
