I added filter-def and filter elements to the hibernate mapping file. Now hbm2java complains. I am using Hibernate 3.1. Does anyone know about the issue and can suggest a work-around? Thanks for any pointers.

yeees, but I can't help much when you just say "it complains" and "fails in building something"

...what about stacktraces, error messages and the files you actually hand to it ?

Below is the mapping file I have. Without the filter-def and filter element, hbm2java generates the java code. I am wondering if the hbm2java that comes with Hibernate 3.1 package may not support the filters? Thanks!


<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping>

<filter-def name="myAppFilter">
<filter-param name="myAppFilterParam" type="java.lang.String"/>
</filter-def>

<class name="myClass" table="MY_TABLE" lazy="false">
<meta attribute="scope-field">protected</meta>
<cache usage="read-write"/>
<id name="id" column="MY_ID" type="java.lang.Long">
<generator class="sequence">
<param name="sequence">MYID_SEQ</param>
</generator>
</id>
<property name="appId" column="APP_ID" type="java.lang.String" length="24" not-null="true"/>
<filter name="myAppFilter" condition=":myAppFilterParam != APP_ID"/>
</class>

</hibernate-mapping>

I just learned the -debug option. So here is the full stack trace, which seems to confirm my earlier guess - the filter-def and filter tag are not supported by the tool in the version we are using?

no it just shows that the syntax of your mapping file is incorrect. fix that and it should work.

If you have found what I did wrong with the filter definition I added, can you please share it?

The new element I added under hibernate-mapping is filter-def as suggested by the error message. Is the tool sensitive with white spaces?

read the error message ;)

it says that filter-def needs to come *after* class

One follow-up question:

The filter-def element defines the named filter. Intuitively, the filter-def should be defined first before the class that uses the defined filter? Am I missing anything else here?
