Hi, all,

my work environment, JBoss5.0.0GA+MySQL, now I use datasource encryption.

my application-policy as follow:

<application-policy name="fgdb-password-encrypted">
 ....

 </application-policy>

I define a mbean as follows:

<mbean code="org.jboss.resource.connectionmanager.TxConnectionManager"
...>
 ...
 <attribute name="JndiName">...</attribute>
 <attribute name="SecurityDomainJndiName">fgdb-password-encrypted</attribute>
 ....
 </mbean>

Now I can't connection database, I find the cause is that it can't get Instance of JBoss Security Subject Factory.

and I find a xml file security-jboss-beans.xml, it has some sentence.

<!-- Instance of JBoss Security Subject Factory -->
 <bean name="JBossSecuritySubjectFactory"
 class="org.jboss.security.integration.JBossSecuritySubjectFactory">
 <property name="securityManagement"><inject bean="JNDIBasedSecurityManagement" /></property>
 </bean>

but I don't know how to get this instance.
so I modify a class BaseConnectionManager2 in this jar jboss-jca.jar
I add as follows sentence,

subjectFactory = new JBossSecuritySubjectFactory();
 ((JBossSecuritySubjectFactory) subjectFactory).setSecurityManagement(new JNDIBasedSecurityManagement());

now my problem disappears, I think mondify JBoss class is not a good way,
Can someone give me some hints?
any help can be appreciated.
