SQL, SSIS, And Stored Procedure

I am trying to execute a stored procedure that runs a SSIS package. This package imports a .csv flat file (from a different server) and appends to an existing table. When I run the package from SQL Server Management Studio it works great. When I execute the Stored Procedure, I get an error stating "The system cannot find the file specified." Eventually, I would like to execute the Stored Procedure from an asp.net webpage button click event.

The code for the stored procedure:

USE [JElog]
GO
DECLARE @return_value int
EXEC @return_value = [dbo].[importGLJEdata]
SELECT 'Return Value' = @return_value
GO

asp.net VB code:

  Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myconn As New SqlConnection(ConfigurationManager.ConnectionStrings("JElog-SQL").ConnectionString)

Dim MyCmd As New SqlCommand("importGLJEdata", myconn)
MyCmd.CommandType = CommandType.StoredProcedure

myconn.Open()
MyCmd.ExecuteNonQuery()
myconn.Close()

End SubThanks,
SMC
