I came across this post regarding adding portlets to the ump.
I copied the custom portlet directory and .war file into the webapps folder on my UMP.
I added an entry for the custom webapp to wasp.cfg <webapps> section
I set auto.deploy.enabled = true in the portal_ext.properties file.
When I go my wasp probe, I see the portlet listed in the webapps tab, and it shows a green play icon.
However, I can't seem to find the custom portlet in the list.
I went to Plugin Configuration in Control Panel, but I do not see the option to add a portlet, as the previous post suggested.
Has this processed changed in UMP 7.5? If so, does anyone have the steps or dopcumentation on adding custom portlets?
