Pass BLOB as parameter to Packaged Stored Procedure

Question

Does JDBC (thin or otherwise) support passing a BLOB as a parameter to a packaged stored procedure in Oracle, or do we have to do an 'insert' statement to get it in?
All the articles I've seen seem to refer to insert and select, but I want to strictly enforce all access to the database being through a package rather than table level access.
We've certainly had no difficulty receiving blobs from the resultset returned by our packaged procedures.
Any help appreciated,
Thanks
Jason.

Can someone please demonstrate exactly how to use formula results as date parameters to a SQL stored procedure?  Keep in mind, there are two parameters to the stored procedure.
I have gleaned this much: Use Add Command and insert the procedure with
EXEC ServerName.dbo.usp_sprocName;1 '{?StringParameter}'
but if I try to do
{CALL ServerName.dbo.usp_SprocName({@Formula1},{@Formula2})}
then it gives the error "No value given for one or more required parameters". 
Both of the parameters are VARCHAR(50).
I have finally found this link: [http://msdn.microsoft.com/en-us/library/ms710248(VS.85).aspx|http://msdn.microsoft.com/en-us/library/ms710248(VS.85).aspx]
This Microsoft site defines the format of the ODBC escape sequences, but I still do not know how to convince Crystal to insert it's parameter results or formula results.
Pulling what's left of my hair out . . .
