> Query params in xml mapping files generate incorrect code for integers and possibly other scalers. In the case below,
> I have tried "int", "integer", "Integer" and "java.lang.Integer" and "Ljava.lang.Integer;"  for the type of parameter "region".
> <query name="com.tgcusa.idmgr.ProgramId.findProgramId">
>     <query-param name="region" type="integer"/>
>     <query-param name="epgser" type="string"/>
>     <query-param name="epgepi" type="string"/>
>     <![CDATA[
>       select pid.tgcsh, pid.tgcser, pid.tgcepi from com.tgcusa.idmgr.ProgramId
>       as pid where pid.region == :region and pid.epgser == :epgser and
>       pid.epgepi = :epgepi
>     ]]>
>   </query>
> The code generator always produces:
> public List findTgcSerForEpgSer(int region, java.lang.String tepgser)
>     {
>         Query query =
>             sessionFactory.getCurrentSession().getNamedQuery("com.tgcusa.idmgr.ProgramId.findTgcSerForEpgSer");
>         query.setParameter("region", region);
>         query.setParameter("tepgser", tepgser);
>         return query.list();
>     }
> Which has the compilation error:
>     [javac] Found 2 semantic errors compiling "/sandbox/mainline/srcroot/sw/tgcs
> vc/lib/java/src/com/tgcusa/idmgr/ProgramIdHome.java":
>     [javac]    171.         query.setParameter("region", region);
>     [javac]                 ^----------------------------------^
>     [javac] *** Semantic Error: No applicable overload for a method with signatu
> re "setParameter(java.lang.String, int)" was found in type "org.hibernate.Query"
> . Perhaps you wanted the overloaded version "org.hibernate.Query setParameter(ja
> va.lang.String $1, java.lang.Object $2) throws org.hibernate.HibernateException;
> " instead?
> It seems that:
> 1) There is ambiguity about the type "integer".  I have seen it generate java.lang.Integer in other  code.
> 2) for "int", a query.setParameter should support int.
> 3) for an Integer object, the setParameter call is ok, but the the method parameter shoud be Integer not int.
