Oracle XDK for Java: method setXSLT

[lion]

Hi All!

how I can use method setXSLT from OracleXMLQuery class
when I try:
java.lang.NoClassDefFoundError: oracle/xdb/XMLType
oracle.xml.sql.query.OracleXMLQuery.setXSLT(OracleXMLQuery.java:747)

code:
...
xmlQuery = new OracleXMLQuery(this.mainDbConn.getConn(),sql);
...
xmlQuery.setXSLT("/[path]/[name].xsl","");
....
