I hav three table, a role table, an action table and a composition permission table which contain roleId and actionId.

The code for RolePos.hbm.xml is
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="system.RolePos" table="role">
<id name="roleId" type="int" column="roleId" unsaved-value="0">
<generator class="increment"/>
</id>

<property name="roleName">
<column name="roleName"/>
</property>

<set name="properties" lazy="true" inverse="true" cascade="all-delete-orphan">
<key column="roleId" />
<one-to-many class="system.PermissionPos" />
</set>

</class>

</hibernate-mapping>

The code for ActionPos.hbm.xml is
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="system.ActionPos" table="action">
<id name="actionId" type="int" column="actionId" unsaved-value="0">
<generator class="increment"/>
</id>

<property name="actionName">
<column name="actionName"/>
</property>

<set name="properties" lazy="true" inverse="true" cascade="all-delete-orphan">
<key column="actionId" />
<one-to-many class="system.PermissionPos" />
</set>
</class>

</hibernate-mapping>

The code for PermissionPos.hbm.xml is
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="system.PermissionPos" table="permission">
<id name="roleId" type="int" column="roleId" unsaved-value="0">
<generator class="assigned"/>
</id>

<id name="actionId" type="int" column="actionId" unsaved-value="0">
<generator class="assigned"/>
</id>

<many-to-one name="roleId" class="system.RolePos" column="roleId"/>

<many-to-one name="actionId" class="system.ActionPos" column="actionId"/>
</class>

</hibernate-mapping>

After run the program, it shows Could not parse mapping document from resource PermissionPos.hbm.xml and Could not parse mapping document from resource PermissionPos.hbm.xml. Can anybody help me? Thanks a lot.

Hi arjensen,

Why you have two ID in one HBM.From where you have read it.

<id name="roleId" type="int" column="roleId" unsaved-value="0">
<generator class="assigned"/>
</id>

<id name="actionId" type="int" column="actionId" unsaved-value="0">
<generator class="assigned"/>
</id>


To avoid these type of problem use XML Editor ,XML Buddy plugin ,Exadel plugin

Hi Dharmendra,

So what should to edit for the composition xml? Should i change to

<property name="roleId" type="int">
<column="roleId" unsaved-value="0"/>
</property>

<property name="actionId" type="int">
<column="actionId" unsaved-value="0"/>
</property>

<many-to-one name="roleId" class="system.RolePos" column="roleId"/>

<many-to-one name="actionId" class="system.ActionPos" column="actionId"/>

I new for hibernate, so not very familiar for it. Thanks for ur help. ;)

Try to see composite tag for hibernate

Hi,

I had look through the reference guide, but it stills could not parse mapping document. In permission(composite xml), i change to
<composite-id class="system.PermissionPos" mapped="true">
<key-many-to-one name="roleId" class="system.PermissionPos" column="roleId"/>
<key-many-to-one name="actionId" class="system.PermissionPos" column="actionId"/>
</composite-id>

so for role xml and action xml does i have to add one-to-many column too?

Hi arjensen,

what is mapped="true" where it is written reference.




<composite-id
name="propertyName"
class="ClassName"
unsaved-value="any|none"
access="field|property|ClassName">

<key-property name="propertyName" type="typename" column="column_name"/>
<key-many-to-one name="propertyName class="ClassName" column="column_name"/>
......
</composite-id>

Let me know your Exp level .That would be great to me to know your understanding so that i could replay according to that

I new to hibernate ;)

Now for rolePos mapping file
<class name="system.RolePos" table="role">

<id name="roleId" type="int" column="roleId" unsaved-value="0">
<generator class="increment"/>
</id>

<set name="permissionPos" lazy="true" inverse="true" >
<key>
<column name="roleId" />
</key>
<one-to-many class="system.PermissionPos"/>
</set>

<property name="roleName">
<column name="roleName"/>
</property>
</class>

actionPos mapping file
<class name="system.ActionPos" table="action">

<id name="actionId" type="int" column="actionId" unsaved-value="0">
<generator class="increment"/>
</id>

<set name="permissionPos" lazy="true" inverse="true" >
<key>
<column name="actionId" />
</key>
<one-to-many class="system.PermissionPos"/>
</set>

<property name="actionName">
<column name="actionName"/>
</property>
</class>

and permissionPos composite mapping file
<class name="system.PermissionPos" table="permission">
<composite-id>
<key-many-to-one name="roleId" class="system.RolePos" not-null="true">
<column name="roleId" />
</many-to-one>

<key-many-to-one name="actionId" class="system.ActionPos" not-null="true">
<column name="actionId" />
</many-to-one>
</composite-id>
</class>

But it still can't run. I really no idea for this..

See some more example in google .
