How do I include external GSPs or template in the GSP file when the template to be included is not under views folder?

Yes, you can easily do that. Here you go:
import grails.gsp.PageRenderer
class MyLib {
static namespace = "foo"
static defaultEncodeAs = "raw"
PageRenderer groovyPageRenderer
def externalTemplate = { attrs, body ->
String externalFilePath = attrs.externalPath
/*
* Put content of that external template to a file inside grails-app/views folder
* with a temporary unique name appended by current timestamp
*/
String temporaryFileName = "_external-" + System.currentTimeMillis() + ".gsp"
File temporaryFile = new File("./grails-app/views/temp/$temporaryFileName")
/*
* Copy content of external file path to the temporary file in views folder.
* This is required since the groovyPageRenderer can compile any GSP located inside
* the views folder.
*/
temporaryFile.text << new File(externalFilePath).text
/*
* Now compile the content of the external GSP code and render it
*/
out << groovyPageRenderer.render([template: "/temp/$temporaryFileName", model: attrs.model])
// Delete the file finally
temporaryFile.delete()
}
}
Now in your actual GSP where you want to include the external GSP, you can write so:
<body>
<foo:externalTemplate externalPath="/home/user/anyExternalFile.gsp" model="${[status: 1}" />
</body>
