Passing a parameter to the struts2 component

I am trying to create a struts2 component using freemarker. I created a file ftl

with code like this:

<script type="text/javascript" src="${parameters.library?default('')}"></script>

It is expected that a named parameter library

will be passed to the component. If the parameter is absent, then the default is a space String

.

In my JSP page, I access this component like this:

<s:component template="mytemplate.ftl">
    <s:param name="library" value="/scripts/mylibrary.js"/>
</s:component>

Unfortunately, no value was specified for the library parameter. It's always empty String

.

I'm using the advice from the tutorial and it seems that the tag s:param

should pass this parameter to the template and make it available. What am I missing here?

Does anyone have any experience creating these components that might shed some light?

Thank.

send parameter with single quotes



<s:component template="mytemplate.ftl">
    <s:param name="library" value="'/scripts/mylibrary.js'"/>
</s:component>

I ended up running into some syntax in the docs that work. I have to reference a parameter like this:



<script type="text/javascript" src="${parameters.get('library')?default('')}">
</script>
