Just Another Stored Procedure Question

[Yusuf]

Hi,
Really2 sorry for asking, i know this has been asked before many times,
i have browsed through the docs, the faqs page, and the mailing lists,
but i can't seem to make this work (oracle): 

oracle procedure : 

PROCEDURE generate_counter (
        v_result         OUT      VARCHAR2,
      v_msco_number    IN       NUMBER,
      v_lca_id         IN       VARCHAR2,
      v_prefix         IN       VARCHAR2,
      v_suffix         IN       VARCHAR2,
      v_total_length   IN       NUMBER
);

in sqlmap : 

<parameterMap id="elions.bas.procCounter.param" class="hashMap">
        <parameter property="hasil" jdbcType="varchar" javaType="string"
mode="OUT"/>
        <parameter property="msco_number" jdbcType="number"
javaType="int" mode="IN"/>
        <parameter property="lca_id" jdbcType="varchar"
javaType="string" mode="IN"/>
        <parameter property="prefix" jdbcType="varchar"
javaType="string" mode="IN"/>
        <parameter property="suffix" jdbcType="varchar"
javaType="string" mode="IN"/>
        <parameter property="length" jdbcType="number" javaType="int"
mode="IN"/>
</parameterMap>

<procedure id="elions.bas.procCounter" parameterClass="hashMap">
{call EKA.SISTEM_KONTROL_SPAJ.GENERATE_COUNTER (#hasil:varchar#,
#msco_number:number#, #lca_id:varchar#, #prefix:varchar#,
#suffix:varchar#, #length:number#)}
</procedure>

in spring dao : 

public String selectCounter(int msco_number, String lca_id, String
prefix, String suffix, int total_length) {
        Map map = new HashMap();
        String hasil = "";
        map.put("hasil", hasil);
        map.put("msco_number", msco_number);
        map.put("lca_id", lca_id);
        map.put("prefix", prefix);
        map.put("suffix", suffix);
        map.put("length", total_length);
        String result = (String)
getSqlMapClientTemplate().queryForObject("elions.bas.procCounter", map
);
        System.out.println("RESULT = " + result);
        System.out.println("HASIL = " + hasil);
        return hasil;
        }

both the String result and hasil contains nothing... can someone help
me? thanks
