Problem with DB2 XML Extender and JDBC on AS/400

P: n/a

I have a problem with the IBM DB2 UDB XML Extender. I`m working on a
iSeries 400 server (AS/400, V5R1) with a
integrated DB2 (my client is NT 4.0 Service Pack 1 with JDK1.1.8). I
want to create XML files out of the DB2 data
using the XML collections method and SQL mapping.
I successfully enabled my database, put the collection.dtd into
DTD_REF, created a DAD file and enabled the
collection (xcolltest01) using the OS/400 command line via Client
Access Express.
I can find the collection in my DB2XML.LIB on the server in the

To compose the XML document I wrote a Java program. When I start this
program (java testxml4), I always get the following
error message:
java.sql.SQLException: [CEE9901] Anwendungsfehler. MCH3402 nicht
überwacht durch QZXMDB2XML bei
Anweisung 0000000062, Instruktion X'0000'.
at ute(
at cute(
at testxml4.<init><>
at testxml4.main<>

When I enter "java testxml4" again right after the error message came,
I get another error message:
# of rows: 0
ReturnCode: -11
ErrorMessage: DXXQ016 Die Eingabetabelle RESULT_TAB konnte nicht
gefunden werden (my result table hasn`t been found, even though I
created a table with that name before)

This is a very interesting message because there seems to be a
connection to the database, so my java prog seems to
work fine.

I don`t know where the fault is:
1. A wrong way of creating a result table or
2. my java code
1. To create a result table I start SQL from the command line (STRSQL)
and write:
Create table RESULT_TAB(doc varchar(8000))

Then I get the information that the table has been created in QGPL but
without connecting to the journal. I don`t know if this is a problem
´cause I can find the empty table in QGPL.

2. Here`s my full java code that connects to the database and calls
the stored procedure dxxRetrieveXML():
import java.sql.*;

public class testxml4 {
public static void main(String[] args) {
testxml4 mysql;
mysql = new testxml4(
"","jdbc:as400 :S4420B1A", "delta",
} //Treibername der DB2-Datenbank; JDBC-URL; Benutzername; Passwort;
means: DB2-Driver; JDBC-URL; Username; Password

public testxml4(String driver, String url, String user, String
password) {
Connection cn;
CallableStatement cs;

try {
cn = DriverManager.getConnection(url, user, password);

cs = cn.prepareCall("CALL DB2XML.dxxRetrieveXML(?, ?, ?, ?, ?, ?,
?, ?, ?, ?)");
cs.setString(1, "XCOLLTEST01"); // CollectionName
cs.setString(2, "RESULT_TAB"); // result table name
cs.setString(3, "xml_document"); // result column name
cs.setString(4, "valid_document"); // valid column name
cs.setInt(5, 0); // override type
cs.setString(6, "NO_OVERRIDE"); // override
cs.setInt(7, 100); // max # of rows

cs.registerOutParameter(8, Types.INTEGER); // actual # of rows
cs.registerOutParameter(9, Types.INTEGER); // return code
cs.registerOutParameter(10, Types.VARCHAR); // error message text

System.out.println("# of rows: " + cs.getInt(8));
System.out.println("return Code: " + cs.getInt(9));
System.out.println("Message Text: " + cs.getString(10));

} catch (Exception e) {

I`m completely frustrated and don`t know what to do. Is there anyone
that can help me solving this problem?

Thanks in advance,

XML Extenders do use an Isolation Level other than NC, so that would require the
table to be journaled/logged. If you create your table in an SQL created
schema, the journaling will happen automatically.
Create table myschema.RESULT_TAB(doc varchar(8000))

You might want to also specify an isolation level on the JDBC connection, I
don't recall the default.

Hi Kent,

thank you so much for your help. I will try to get the table journaled
tomorrow. I thought that my problem could be the
"Not-Connecting-To-The-Journal"-thing, but I had no idea how to create
a journaled table.
Maybe your advice will solve my problem.
