Stored Procedure with input parameters using esql?

Title: Stored Procedure with input parameters using esql?

I want to execute a stored procedure that requires input parameters using the esql logicsheet, but am having difficulty. I can call stored procedures that take no inputs just fine.

Is there a working example/samle code of how to do this? I could only find one brief example in the userdocs and it still does not make sense to me ;(

I have this stored procedure: {? = call get_person(?,?,?,?)}

The first 3 input parameters can accept NULL and the last one will be an actual value.

I have this code using esql logicsheet:
-----------------------------------------------------------------------------
<esql:execute-query>

        <esql:call needs-query="true" >
                        {? = call get_person(
                        <esql:parameter direction="In" type="String"><xsp:expr>NULL</xsp:expr></esql:parameter>,
                        <esql:parameter direction="In" type="String"><xsp:expr>NULL</xsp:expr></esql:parameter>,
                        <esql:parameter direction="In" type="String"><xsp:expr>NULL</xsp:expr></esql:parameter>,
                        <esql:parameter direction="In" type="String"><xsp:expr>'46465445'</xsp:expr></esql:parameter>)}
                </esql:call>

... stuff to process results ....
</esql:execute-query>
-----------------------------------------------------------------------------
But I receive this error:

type fatal
