XPRESS invoke exception... why?

Question

I got this error in the syslog of my was...
[11/17/11 9:38:34:407 CET] 00000319 SystemOut O XPRESS <invoke> exception:
[11/17/11 9:38:34:415 CET] 00000319 SystemOut O com.waveset.util.WavesetException: Couldn't find method executeQuery() in class oracle.jdbc.driver.OraclePreparedStatementWrapper
I am a bit baffled here...
Anyone seen this and have an idea on how to fix?
Call is...

Well, doing an invoke with connection and preparedStatement as references did not, as I expected, work...
XPRESS <invoke> exception:
Couldn't find method execute(oracle.jdbc.driver.OraclePreparedStatementWrapper) in class com.waveset.util.PooledConnection ==> java.lang.NoSuchMethodException: com.waveset.util.PooledConnection.execute(oracle.jdbc.driver.OraclePreparedStatementWrapper) Reverting back to just an invoke with preparedStatement as reference did as before render this message...
XPRESS <invoke> exception:
Couldn't find method execute() in class oracle.jdbc.driver.OraclePreparedStatementWrapper So I decided to write it in javascript within scripttags instead...
      <Rule name="SQL Command" protected="false" protectedFromDelete="false" hidden="false" localScope="false" authorize="false">
        <RuleArgument name="command" locked="false" />
          <RuleArgument name="args" locked="false" />
        <RuleArgument name="resourceName" locked="false" />
        <RunAsUser>
          <ObjectRef type="User" id="#ID#Configurator" name="Configurator" isWeak="false" />
        </RunAsUser>
        <block trace="false">
          <defvar name="connection">
            <rule name="RuleLibrary_SEB-Common:getConnectionFromDatabaseAdapter" passThrough="false">
              <argument name="resourceName" value="$(resourceName)" />
            </rule>
          </defvar>
          <defvar name="result" />
          <setvar name="result">
            <script>
var con = env.get("connection");
var cmd = env.get("command");
var args = env.get("args");
java.lang.System.out.println("SQL Command connection: "+con);
java.lang.System.out.println("SQL Command command: "+cmd);
java.lang.System.out.println("SQL Command args: "+args);
if (con == null) {
  throw new Packages.com.waveset.util.WavesetException('Can not connect to metadata database.',Packages.com.waveset.msgcat.Severity.ERROR);
var stm = con.prepareStatement(cmd);
var i=0;
while (i &lt; args.size()){
  java.lang.System.out.println("SQL Command prepareStatement( "+i+", "+args.get(i)+" )");
  stm.setString(i+1,args.get(i));
  i++;
var result = null;
result = stm.executeUpdate();
if (stm != null) stm.close();
java.lang.System.out.println("SQL Command result: "+result);
result;
            </script>
          </setvar>
            <rule name="RuleLibrary_SEB-Common:closeConnectionFromDatabaseAdapter" passThrough="false">
            <argument name="resourceName">
              <ref>resourceName</ref>
            </argument>
            <argument name="connection">
              <ref>connection</ref>
            </argument>
          </rule>
          <ref>result</ref>
        </block>
      </Rule>...and voaila, it works!
Output in the was log...
