[opencms-dev] Multiple Content Areas

[Alexander Kandzior]

Jens,

you might try the following:

<%
String target = "/uri/of/the/page/file";
String element = "name_of_element";
com.opencms.file.CmsObject cms; // init this e.g. with
CmsJspActionElement.getCmsObject()

com.opencms.template.CmsXmlTemplate template = new
com.opencms.template.CmsXmlTemplate();
byte[] res = template.getContent(cms, target, element, null);
String result = new String(res, cms.getRequestContext().getEncoding());
// now check content of result to see if it is empty "" or not
%>

I didn't try this myself so I am not 100% if it works or not. If it
dosen't, try around with this and have a look at the source of
CmsJspActionElement method "public String getContent(String target)".

Best Regards,
Alex.

Is there any way to check whether one content area is empty (i.e. the
content editor did not enter anything in that particular body)? The
return type of CmsJspActionElement.include(...) is void, so I can't
directly check it. Is there any way to retrieve the content of a content
area as, say, a String, where I could further process it in my JSP code?

Thanks for any hints,

Jens
