Hello All - Can I use the request-attributes in data-sly-include like the below so that I can use the values in JSP.
E.g.
<sly data-sly-include="${ '/apps/project-name/components/../manipulate.jsp' @ requestAttributes='abc.html'}" />

 

Please confirm if the syntax is correct. if so,  what is the parameter name should I use it to get the value?

<%= request.getParameter("param") %>

Hi @v1101 

 

In order to pass values to JSP, you are in right direction to use requestAttributes. But the parameter requestAttributes takes a map instead of a single value. In order to set a map and then pass as request parameter refer https://docs.adobe.com/content/help/en/experience-manager-htl/using/htl/block-statements.html#request-attributes.

 

 

public class Settings extends WCMUsePojo { // used to pass is requestAttributes to data-sly-resource public Map<String, Object> settings = new HashMap<String, Object>(); @Override public void activate() throws Exception { settings.put("property1", "abc.html"); } }

 

you can also use sling model to set key value pairs.

 

you can then call jsp like this:

 

<sly data-sly-use.myclass="com.adobe.examples.htl.core.hashmap.Settings" data-sly-include="${ '/apps/project-name/components/../manipulate.jsp' @ requestAttributes=myclass.settings}" />

 

 
In JSP file, you can get this property value like :

 

<%@include file="/libs/granite/ui/global.jsp"%> <%=request.getAttribute("property1")%>​

 

 

you can not use getparameter as it will provide you query parameter in the URL.

 

Hope it helps!

Thanks!

Hi @v1101 ,

Yes, you can pass request-attributes [0] to data-sly-include and data-sly-resource in order to use them in the receiving HTL-script. This allows you to properly pass-in parameters into scripts or components:

 

<sly data-sly-include="${ 'something.html' @ requestAttributes=a_map_of_attributes}" />


[0]: https://docs.adobe.com/content/help/en/experience-manager-htl/using/htl/block-statements.html#request-attributes

 

In regards to accessing the parameter name, check https://stackoverflow.com/questions/1890438/how-to-get-parameters-from-the-url-with-jsp for more details.

 

 

Thanks!!

      Thanks nupurjain for the response. Basically I want to pass the specific clientlib category details of the component to the JSP and the category details may vary based on every component.
