Hallo Zusammen,

ich habe seit längerem das folgende Problem, den ich nicht gelöst bekomme. Vielleicht kennt einer von Euch sich besser aus. Wäre Ihn/Ihr sehr dankbar für einen Ratschlag/Tipp.

Folgende Laufzeitumgebung habe ich:
- WAS 6.0 / integriert in IBM RAD 6.1
- IBM DB2 Version 9.1

ich hab zwar noch nie in JAVA programmiert aber auffällig ist das im mapping file name="actStatus" type="long" ist in im setter BigInteger.
kommt denn die exeption auch wenn

public Long getActStatus() {
return this.actStatus;
}

public void setActStatus(Long actStatus) {
this.actStatus = actStatus;
}

ist ?

Hello Folks,

thank a lot for your helps and advices:

The solution was:
A) I changed the HQL-Statement to:
result = session.createQuery("select rvr from RVarRegions rvr where actStatus <> 1 ").list();

B) I changed in the Java-File the datatype from java.lang.Long to java.math.BigDecimal:

public class RVarRegions implements java.io.Serializable {
private BigDecimal actStatus;
private BigDecimal companyId;

public BigDecimal getActStatus() {
return this.actStatus;
}

public void setActStatus(BigDecimal actStatus) {
this.actStatus = actStatus;
}

public BigDecimal getCompanyId() {
return this.companyId;
}

public void setCompanyId(BigDecimal companyId) {
this.companyId = companyId;
}
}

C) Also the database driver is now changed from "COM.ibm.db2.jdbc.app.DB2Driver" to "com.ibm.db2.jcc.DB2Driver"

D) Changes in the config file of hibernate hibernate.cfg.xml
<property name="hibernate.bytecode.use_reflection_optimizer">true</property>
...
<property name="hibernate.connection.driver_class">com.ibm.db2.jcc.DB2Driver</property>


Thanks again for your helps & advices


Best Regards,

Hallo Uwe Lesta,

Infor für Dich: Nein, ich habe den hbm.xml file nicht angepasst. Da steht weiterhin long als Typ!
