calling a strored procedure from a cfcomponent

I get the following error when I invoke a cfcomponent which has a cffunction that calls a stored procedure:

Here is the fault returned when invoking the web service operation:

AxisFault
 faultCode: {http://xml.apache.org/axis/}HTTP
 faultSubcode:
 faultString: (500)Internal Server Error
 faultActor:
 faultNode:
 faultDetail:
      {}:return code:  500

      {http://xml.apache.org/axis/}HttpErrorCode:500
 
 
The error occurred in C:\CFusionMX7\wwwroot\accountInformation.cfm: line 54
 
52 :        <cfinvoke  webservice="http://LOCALHOST/component_lookup1a.cfc?wsdl" method="getAcctInfo"   returnvariable="rst1">  
53 :              <cfinvokeargument name="acct_id" value="#v_acct_ID#">
54 :              <cfinvokeargument name="premID"   value="#v_prem_id#">  
55 :       </cfinvoke>
 

Here is the component

<cfcomponent>
<cffunction name = "getAcctInfo"  access="remote"    returntype="query">
<cfargument name= "acct_id" required = "true" displayname="acct_id" >
<cfargument name = "premID" required = "true"  displayname="premID">

<cfstoredproc procedure= "acctLookup2" datasource= "CFDM">

<cfprocparam type= "In" cfsqltype=   "CF_SQL_CHAR"    value= "#arguments.acct_id#" null="no">
<cfprocparam type= "In" cfsqltype=   "CF_SQL_CHAR"    value= "#arguments.premID#" null="no">
<cfprocparam type= "OUT" cfsqltype=  "CF_SQL_CHAR"    null="no"  variable = "p_acct_id">
<cfprocparam type= "OUT" cfsqltype=  "CF_SQL_CHAR"    null="no"  variable = "p_address">
<cfprocparam type= "OUT" cfsqltype=  "CF_SQL_CHAR"    null="no"  variable = "p_city">
<cfprocparam type= "OUT" cfsqltype=  "CF_SQL_CHAR"     null="no"  variable = "p_postal">
<cfprocresult name= "acctLookup" resultset="rst1">
</cfstoredproc>
<cfreturn  rst1>
</cffunction>
</cfcomponent>

Here is the stored procedure:

CREATE OR REPLACE procedure acctLookup2(

p_acct_num in  varchar2,
p_premID in varchar2,
p_acct_id out varchar2,
p_address out varchar2,
p_city out varchar2,
p_postal out varchar2)
as
Begin
      SELECT ACCT_ID, ADDRESS1, CITY,  POSTAL
      into  p_acct_id, p_address, p_city, p_postal
      FROM V_ACCOUNT_INFO_FAST
      WHERE acct_id = p_acct_num
      AND PREM_ID = p_premID;
End ;

Please help
