Complex Target mapping UDF and FCC - urgent

Hi,

I need help as i am stuck in one place due to the error in Java when i am following the below link-

File Content Conversion for Multi Hierarchical Structure

I have a simple Source -

<Message>

<Record> - 1..Unbounded

     <Header> - 1..1

    <field1>....<fieldn>

     <Line> - 1...Unbounded

    <field1>....<fieldn>

</Record>

</Message>

Target Structure -

<File>

<FileHdr> - 1..1

<TrnHdr> - 1..Unbounded  - (Mapped from Source - <Record>)

    <Trn1> - 1..1  (Mapped from Source - <Header>)

    <Trn2> - 1..1  (Mapped from Source - <Header>)

    <TrnDetails> - 1..Unbounded   - (Mapped from Source - <Line>)

<Trailer>    - 1..1

</File>

As FCC can only handle 3 levels, I am facing an issue as the above is 4 levels.

If FCC can handle the above Target, mapping can be done in 1 step.

I am following the above blog but now i am facing issue of error when i am creating the Populate_Result-

Function populate_result, Line 1:

cannot find symbol symbol  : method Iterator() location: interface java.util.Set Iterator It = hashMap.keySet().Iterator();                             ^ Note:<server path>_.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details.

Note: <Server path>.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 1 error

I need help as I want to keep to Graphical mapping instead of using XSLT or huge Java code.
