Problems with SocketAcceptor usage from Spring
SVN revision 534322 breaks my Spring configuration on JDK 1.5. My
problem is quite similar to the problem posted by Vic Ganora but the
fix applied did not work for me.
The problem seems to occur because the beanInfo for SocketAcceptor
doesn't report the setter for the localAddress property because
getLocalAddress returns an instance of INetSocketAddress while the
related setter accepts SocketAddress instances.
IMHO it would be more clear to use SocketAddress in both cases and
furthermore it would solve my problem.
Exception extract:
Exception in thread "main"
org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'org.apache.mina.transport.socket.nio.SocketAcceptor'
defined in file [xxxxx.xml]: Error setting property values; nested
exception is org.springframework.beans.NotWritablePropertyException:
Invalid property 'localAddress' of bean class
[org.apache.mina.transport.socket.nio.SocketAcceptor]: Bean property
'localAddress' is not writable or has an invalid setter method. Does
the parameter type of the setter match the return type of the getter?

Yep. It looks like Spring team fixed their issue.

You need to specify the property editor for InetSocketAddress. You
could add the following element:
<!-- This makes it possible to specify java.net.SocketAddress values
(e.g. :1234 below) as Strings.
They will be converted into java.net.InetSocketAddress objects by
Spring. -->
<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">
<property name="customEditors">
<map>
<entry key="java.net.SocketAddress">
<bean
class="org.apache.mina.integration.spring.InetSocketAddressEditor" />
</entry>
</map>
</property>
</bean>
HTH,

Hi,
i just switched to Spring version 2.0.4 - now the exception looks a
little bit different:
org.springframework.beans.TypeMismatchException: Failed to convert
property value of type [java.lang.String] to required type
[java.net.InetSocketAddress] for property 'localAddress'; nested
exception is java.lang.IllegalArgumentException: Method must not be
null
at org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:385)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1085)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:835)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:423)
After doing some debugging the cause is that Spring's
BeanWrapperImpl.convertForProperty tries to acquire a
PropertyDescriptor via
cachedIntrospectionResults.getPropertyDescriptor method but this
PropertyDescritor instance has write method set to null for
localAddress Property which causes the later exception. I'm using jdk
1.5...

Which version of Spring framework are you using? Did you try with the
latest version of Spring?
