[opencms-dev] How to list files from a folder in opencms?

[Patric Dosch]

Hey Mihai,

>> I don't know how to read data from the resource type(xml), which I can access using el expression.
But ${value.YourFieldName} is an el expression.
Now you need the value in your java world? Correct?


The best way should be to use a el-function. This https://newfivefour.com/tomcat7-el-custom-function.html seems to be a nice example. As far as I know the web.xml stuff is not needed anymore.


A not so nice way:

<c:set var=”yourVar” value=”${value.YourFieldName}”/>

<%
String yourVar = (String) pageContext.getAttribute(“yourVar”);
%>

Hope to understand your problem correctly.
But that are java questions and not opencms questions 😊

Regards, Patric

I don't need the value to be rendered in the HTML, I need to process it in the formatter (in the Java code between <% %>. Any time the resource type is processed via formatter I need to get a url from a field and then process it, not just output it in the HTML using el expressions.
How can I do that?

Thanks!
Mihai

This should help: http://documentation.opencms.org/opencms-documentation/content-in-opencms/formatters-and-their-configuration/index.html#4.2

So ${value.YourFieldName} holds the information

I need to create a new resource type in opencms which have 1 field. The field is for a target folder.
Every time I select a folder from VFS and save the resource(xml) the formatter will render a the list of files from the specified folder.

I managed to create a jsp file which will create the list of files needed, but only with the target folder hardcoded. I don't know how to read data from the resource type(xml), which I can access using el expression.
Can you help me?
