[opencms-dev] requestContext cannot be resolved

[Paoletti Corrado]

Hi,
it works! Thank you very much.

Despite last two rows in suggested article I replaced them with:

String prop = "";
try {
                prop = cmsObject.readPropertyObject(cmsAction.getRequestContext().getUri(), "cosa", false).getValue();
}
catch ( CmsException exc ) {}
if ( CmsStringUtil.isEmptyOrWhitespaceOnly( prop ) ) {
                prop = "";
}

I think it isn't the best solution (I'm not Java wizard!) but I made this change because if I use:

CmsProperty myprop = cmsObject.readPropertyObject(cmsAction.getRequestContext().getUri(), "cosa", false);
prop = (myprop != null) ? myprop.getValue() : "";

and cosa property exists but has not value and test prop value:

if ( prop == "" ) {
                out.println("prop has not value");
} else {
                out.println("prop has value " + prop);
}

I always have "prop has value null" and I don't understand why.

For further reference the complete code is:

<%@ page import="org.opencms.jsp.CmsJspActionElement,
                 org.opencms.file.CmsObject,
                 org.opencms.file.CmsResource,
                 org.opencms.file.CmsProperty,
                 org.opencms.main.CmsException,
                 org.opencms.util.CmsStringUtil,
                 org.opencms.main.OpenCms" session="true" %>
<%@taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

<%
String prop = "";

CmsJspActionElement cmsAction = new CmsJspActionElement(pageContext, request, response);
CmsObject cmsObject = cmsAction.getCmsObject();

try {
                prop = cmsObject.readPropertyObject(cmsAction.getRequestContext().getUri(), "cosa", false).getValue();
}
catch ( CmsException exc ) {}

if ( CmsStringUtil.isEmptyOrWhitespaceOnly( prop ) ) {
                prop = "";
}
%>

Hi Corrado,

try this:

CmsProperty titleProp = cmsObject.readPropertyObject (cmsAction.getRequestContext().getUri(), "Title", false);

Best regards

Hi all,

in my template I'd like to read a custom property.



Reading article:



http://www.opencms-wiki.org/wiki/Read_a_property_of_an_arbitrary_CmsResource



I copied and pasted code suggested but when I click over a html based on the template I get the error:



Unable to compile class for JSP:

An error occurred at line: 15 in the jsp file: [my jsp file]

requestContext cannot be resolved



I don't know what i'm doing wrong.



Thank you.
