properties ref fail

[hoangthang]

I'm using Spring 1.1.1, and have some trouble with ref, because I want share some properties to all my JndiObject. my applicationContext-jms.xml

    <bean id="QMTestCF" class="org.springframework.jndi.JndiObjectFactoryBean">
    	<property name="jndiEnvironment"><ref local="ref"/></property>    		
        <property name="jndiName"><value>cn=QM_Test,cn=jms,cn=thailh</value></property>
    </bean>
    
	<bean id="ref" class="java.util.Properties">
		<constructor-arg>
			<props>
				<prop key="java.naming.factory.initial">com.sun.jndi.ldap.LdapCtxFactory</prop>
    			<prop key="java.naming.provider.url">ldap&#58;//192.100.100.12&#58;389/dc=cicat,dc=com</prop>
			</props>
		</constructor-arg>
	</bean>

when i run some test:

FileSystemXmlApplicationContext context = 
            new FileSystemXmlApplicationContext("/Web Content/WEB-INF/classes/applicationContext-jms.xml");

i've got Exception:

since java.util.Properties extends java.util.Hashtable, you can use the following workaround:

  <bean id="ref" class="java.util.Hashtable">
    <constructor-arg>
      <map>
        <entry key="java.naming.factory.initial">
          <value>com.sun.jndi.ldap.LdapCtxFactory</value>
        </entry>
        <entry key="java.naming.provider.url">
          <value>ldap&#58;//192.100.100.12&#58;389/dc=cicat,dc=com</value>
        </entry>
      </map>
    </constructor-arg>
  </bean>

<bean id="ref" class="java.util.Properties">
<constructor-arg>
<props>
<prop key="java.naming.factory.initial">com.sun.jndi.lda p.LdapCtxFactory</prop>
<prop key="java.naming.provider.url">ldap://192.100.100.12:389/dc=cicat,dc=com</prop>
</props>
</constructor-arg>
</bean>

actually, this declaration will be executed as

  Properties ref = new Properties(props);
  //ref.isEmpty() returns true

which is very different from

  Properties ref = new Properties();
  ref.putAll(props);
  //ref.isEmpty() returns false

thank you, now i am understand it, no more wonder. Another way working well is

    <bean id="baseJNDI"  abstract="true">    	
		<property name="jndiEnvironment">
    		<props>
				<prop key="java.naming.factory.initial">com.sun.jndi.ldap.LdapCtxFactory</prop>
    			<prop key="java.naming.provider.url">ldap&#58;//192.100.100.12&#58;389/dc=cicat,dc=com</prop>
			</props>
		</property>
	</bean>	

    <bean id="QMTestCF" parent="baseJNDI" class="org.springframework.jndi.JndiObjectFactoryBean">    		
        <property name="jndiName"><value>cn=QM_Test,cn=jms,cn=thailh</value></property>
    </bean>

but I have Problem, but it does't matter:

Severity	Description	Resource	In Folder	Location	Creation Time
2	Attribute "abstract" must be declared for element type "bean".	applicationContext-jms.xml	mqdemo/Java Source	line 21	October 5, 2004 12:04:07 PM

to use abstract, you need to migrate / upgrade Spring Framework to version 1.1
