The top_head.jsp dynamic includes load additional links in the theme’s head.
It uses the following keys:
Load additional links in the theme’s head before the existing ones:
/html/common/themes/top_head.jsp#pre
Alternatively, you can load additional links in the theme’s head, after the existing ones:
/html/common/themes/top_head.jsp#post
The example below injects a link into the top of the top_head.jsp:
@Component(immediate = true, service = DynamicInclude.class)
public class CssTopHeadDynamicInclude extends BaseDynamicInclude {
@Override
public void include(
HttpServletRequest request, HttpServletResponse response,
String key)
throws IOException {
PrintWriter printWriter = response.getWriter();
String content =
"<link href=\"http://localhost:8080/o/my-custom-dynamic-include/css/mentions.css\"
rel=\"stylesheet\"
type = \"text/css\" />";
printWriter.println(content);
}
@Override
public void register(DynamicIncludeRegistry dynamicIncludeRegistry) {
dynamicIncludeRegistry.register("/html/common/themes/top_head.jsp#pre");
}
}
Page Source:
<head>
...
<link href="http://localhost:8080/o/my-custom-dynamic-include/css/mentions.css" rel="stylesheet" type="text/css">
...
</head>
Note that the link’s href attribute’s value
/o/my-custom-dynamic-include/ is provided by the OSGi module’s
Web-ContextPath (/my-custom-dynamic-include in the example).
Now you know how to use the top_head.jsp dynamic includes.
