OK I put chain module to cocoon.xconf

    <component-instance
 
class="org.apache.cocoon.components.modules.input.JXPathMetaModule" 
             logger="core.modules.input.utils" name="jxpath">
		
            <input-module name="chain"/>

		<function name="java.lang.String" prefix="str"/>

                <package name="java.util" prefix="util"/>
    </component-instance>
in chain module is always string attribute "dn" ()
    <component-instance 
 
class="org.apache.cocoon.components.modules.input.ChainMetaModule" 
       logger="core.modules.input" 
       name="chain">
      <input-module name="request-param"/>
      <input-module name="request-attr"/>
      <input-module name="session-attr"/>
      <input-module name="defaults"/>
</component-instance>

so how can I access to length of the string in dn attribute ?
the example str:length(dn) do not work
The output of the wrapped module is the new context object in JXPath 
speak. So it should be {jxpath:str.length(.)} (?)
Please see JXPath homepage for correct syntax.
