URGENT!iBATIS not evaluating value in #value# when accessing ORACLE

Question

Hi,
I am unable to run an SQl to select a record set from oracle when i specify the value in where condition in the following manner.
This is my sql query in XML file:
<select id="getContractor" resultMap="contractorResult" parameterClass="contractor">
select EIXID as eixid, FIRST_NAME as first_name, LAST_NAME as last_name from TB_CONTRACTOR where EIXID = #eixid#
</select>
But, when i hard code the value in sql as follows it works fine and retrieves the record.
<select id="getContractor" resultMap="contractorResult" parameterClass="contractor">
select EIXID as eixid, FIRST_NAME as first_name, LAST_NAME as last_name from TB_CONTRACTOR where EIXID = '12345'
</select>
Has anyone faces this issues. What can be the possible reason for this issue? Is there an alternate way to do it (Without using stored procedure). Please help!!
Its urgent.

Bingo. The issue is that Oracle can apply implicit conversion between a
value passed in with the SQL as it's parsed, so it will equate a passed
in "ABC" with the real table value "ABC ". However, if the query is
parsed with a parametrer marker instead, such as in a PreparedStatement,
you lose the implicit conversion, so "ABC" != "ABC ". The only solutions
are to:
1 - redefine the column as VARCHAR2(9)
2 - Pad all your parameter values to 9 characters, (send "ABC "
3 - File a TAR asking Oracle to enhance it's query plan engine to apply
the same implicit conversion of a string parameter as it would have done
to a string value passed in in the original SQL. (Good luck on this one... ;) )
