Question

I have received a project with many lines like the following ones:

HtmlOutputText content = new HtmlOutputText();
ValueBinding vb = dashBoardBean.getApplication()
    .createValueBinding(columnas[cont][1]);
content.setValueBinding("value", vb);

Eclipse, with Java 5, marks them as deprecated (both class ValueBindingand the method setValueBinding).

So I looked the API for HtmlCommandLink.setValueBinding() (it actually is at UIComponentBase) and found this:

Deprecated. This has been replaced by UIComponent.setValueExpression(java.lang.String, javax.el.ValueExpression).

So I changed the last line code to the following:

content.setValueExpression("value", null);

But now I get a compiler error.

I also tried:

UIComponent uic;
uic.setValueExpression("", null);

And get the same error:

The type javax.el.ValueExpression cannot be resolved. It is indirectly referenced from 

required .class files

What’s the meaning of that error? How can I solve it?

You need the JSF 1.2 (or greater) jars on your classpath.
