Hi,
please use telnet tool instead of SUM which is simple and easy. Please refer the blog (JAS-ADM)DeployController Commands - SAP Netweaver Application Server Java - SCN Wiki
Also check this SAP note 1715441 - How to Deploy/Undeploy/Redeploy SCA/ SDA/ EAR/ WAR files on J2EE servers on Netweaver release:7.1, 7.2, 7.3, 7.4 and 7.5
Hope this helps.
Thanks,
Pradeep
