1. Re: Extracting Copyright-value (Atle Enersen)

Helo good people.

Still at the same problem, but I think I am getting closer...

In the code pasted below I am trying to fetch an images copyright-value:

<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>
        <% 
            org.opencms.jsp.CmsJspActionElement cmsElem = new org.opencms.jsp.CmsJspActionElement(pageContext, request, response);
            org.opencms.file.CmsObject cmsObject = cmsElem.getCmsObject();
            String currentUri = cmsObject.getRequestContext().getUri();
            String imageUri = cmsObject.readPropertyObject("ImageTop", currentUri, true).getValue();
            String copyright = cmsObject.readPropertyObject("Copyright", currentUri, true).getValue();
            out.println("<p><strong>Image URI:</strong> " + imageUri + "</p>");
            out.println("<p><strong>Copyright:</strong> " + copyright + "</p>");
        %>

It failes with this exception: Container-page element "/sites/enersen/.content/enersenarticlesimple/enersenarticlesimple_00004.xml" could not be rendered with formatter "/system/modules/org.enersen.core/formatters/enersenarticlesimple.jsp".

org.apache.jasper.JasperException: javax.servlet.ServletException: org.opencms.file.CmsVfsResourceNotFoundException: Error reading resource from path "/ImageTop".

Any help would be appreciated.

Best regards, Atle.

Thanks, Alex.


But I still have a problem I am afraid. I am not able to extract the actual path of the image, or the image name. Here noted as "path-to-your-image".

1. Re: Extracting Copyright-value (Alex Kandzior)




You need to read the "Copyright" property from the file resource.


Traditional tag notation:
<c:set var="imageCopyright"><cms:property name="Copyright" file="%path-to-your-image%" default="" /></c:set>


More modern direct EL notation:
<c:set var="imageCopyright" value="${cms.vfs.readResource['%path-to-your-image%'].property['Copyright']}" />


For further inspiration, you may also look here (around line 230):

Kind regards,
