The first step is to download the 'Integration Components' to the Jasper Server machine and then install them using the java command mentioned.
The following example was run from a Windows Jasper Server (For Linux, the steps are the same only adjust the paths and remove the .exe from the java command)
Example:
OneClick Web Page ~~> Administration ~~> Report Manager ~~> Jasper Integration
Copy 'spectrumConfigInstaller.jar' to the Jasper Server Machine
Install the 'spectrumConfigInstaller.jar' using the java and the command: java.exe -jar "C:\Users\Administrator\Downloads\spectrumConfigInstaller.jar" -install
Example with output
C:\Program Files\CA\SC\CA Business Intelligence\java\bin>java.exe -jar "C:\Users\Administrator\Downloads\spectrumConfigInstaller.jar" -install
To complete the pre-installation step, provide the following details.
Enter the CABI Apache-Tomcat Home Location:C:\Program Files\CA\SC\CA Business Intelligence\apache-tomcat\
Enter the CABI Webapp Name (Default: jasperserver-pro):
