Exception when deploying a XMBean
I have a standard MBean that deploys fine on JBossesb-server-4.6 (JDK 1.5). I used twiddle to create the XMBean XML from the MBean. I then changed the jboss-service.xml to
<?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE server PUBLIC "-//JBoss//DTD MBean Service 3.2//EN" "http://www.jboss.org/j2ee/dtd/jboss-service_3_2.dtd"> <server> <!-- Specify required library jars as needed. --> <classpath codebase="." archives="*" /> <!-- Mail Service --> <mbean code="com.mail.MailService" name="com.mail:service=MailService" xmbean-dd="mailservice-xmbean.xml"> </mbean> </server>
The mailservice-xmbean.xml looks like
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mbean PUBLIC "-//JBoss//DTD JBOSS XMBEAN 1.2//EN" "http://www.jboss.org/j2ee/dtd/jboss_xmbean_1_2.dtd"> <!-- xmbean descriptor generated by 'twiddle' on Fri Sep 25 12:51:00 EDT 2009 for 'com.mail:service=MailService' --> <mbean> <description>Management Bean.</description> <class>com.mail.MailService</class> <constructor> <description>MBean Constructor.</description> <name>com.mail.MailService</name> </constructor> &defaultAttributes; <attribute access='read-write' getMethod='getMailFromName' setMethod='setMailFromName'> <description>MBean Attribute.</description> <name>MailFromName</name> <type>java.lang.String</type> </attribute> <attribute access='read-write' getMethod='getMailFrom' setMethod='setMailFrom'> <description>MBean Attribute.</description> <name>MailFrom</name> <type>java.lang.String</type> </attribute> <attribute access='read-only' getMethod='getStateString'> <description>MBean Attribute.</description> <name>StateString</name> <type>java.lang.String</type> </attribute> <attribute access='read-only' getMethod='getState'> <description>MBean Attribute.</description> <name>State</name> <type>int</type> </attribute> <attribute access='read-write' getMethod='isEnabled' setMethod='setEnabled'> <description>MBean Attribute.</description> <name>Enabled</name> <type>boolean</type> </attribute> <attribute access='read-only' getMethod='getName'> <description>MBean Attribute.</description> <name>Name</name> <type>java.lang.String</type> </attribute> <attribute access='read-write' getMethod='getMailURL' setMethod='setMailURL'> <description>MBean Attribute.</description> <name>MailURL</name> <type>java.lang.String</type> </attribute> <operation> <description>MBean Operation.</description> <name>start</name> <return-type>void</return-type> </operation> <operation> <description>MBean Operation.</description> <name>jbossInternalLifecycle</name> <parameter> <description></description> <name>p1</name> <type>java.lang.String</type> </parameter> <return-type>void</return-type> </operation> <operation> <description>MBean Operation.</description> <name>destroy</name> <return-type>void</return-type> </operation> <operation> <description>MBean Operation.</description> <name>create</name> <return-type>void</return-type> </operation> <operation> <description>MBean Operation.</description> <name>sendTestMessage</name> <return-type>void</return-type> </operation> <operation> <description>MBean Operation.</description> <name>stop</name> <return-type>void</return-type> </operation> <operation> <description>MBean Operation.</description> <name>sendTestMessage</name> <parameter> <description></description> <name>p1</name> <type>java.lang.String</type> </parameter> <return-type>void</return-type> </operation> &defaultOperations; </mbean>

I don't understand why the exception is getting thrown. There is a MailServiceMBean interface that the MailService implements. What am I missing?
