What can cause Content Platform Engine to fail deployment on WAS 8.5.5.9 with No valid target is specified error?
When installing CPE on WebSphere 8.5.5.9, the deployment task fails with "No valid target is specified in the ObjectName WebSphere:cell=YourCell, node=YourNode ,server=YourServer". All prerequisites were checked, including "EJB tool for pre-EJB 3.0 modules"
Though WAS 8.5.5.9 is the first version to support Java 1.8, CPE 5.2.1.x only supports Java 1.6 and 1.7 as noted in the Software Compatibility Report: http://ibm.co/2agCn1X.
Down grade to Java 1.6 or 1.7 before proceeding with the deploy task. Also confirm you've selected the correct deployment type (Standard, Network Deployment, or Cluster) and the JVM, node and cell names are correctly selected in the Configuration Manager (CMUI) by using the drop down lists provided.
Please review the Limitation when you use the ejbdeploy command with Java 1.8 https://www.ibm.com/support/knowledgecenter/en/SSEQTP_8.5.5/com.ibm.websphere.base.doc/ae/rtrb_ejbdeploy390.html

This error can also be caused if the target truly can not be found. For example, in the deployment task in CMUI, if the JVM name is manually typed in the application server field and it's wrong. Always use the drop downs to select server, cell and node names in the Application Server properties as well as the deployment task in CMUI.
On that note: Use managesdk command to switch java versions being used by the profile that will be hosting the jvm that CPE will be deployed to.
