Hi
I'm trying to finish https://issues.jboss.org/browse/AS7-1371 but I ran
into a problem with the class loader. I need way to load the class for a
specified JDBC driver, but I can't seem to figure out how to make it
available on the classpath too my authentication service.
I try to load the connection class like this, and testing it with the
existing H2 JDBC driver:
ClassLoader original = null;
try {
original = Thread.currentThread().getContextClassLoader();
if (original != null) {
Thread.currentThread().setContextClassLoader(null);
}
Class.forName(this.driver).newInstance();
} finally {
if (original != null) {
Thread.currentThread().setContextClassLoader(original);
}
}
The user can setup a outbound connection to a database for authentication,
by using the configuration below
<security-realm name="ManagementRealm">
<authentication>
<local default-user="$local"/>
<database connection="db" plain-text="true">
<!-- simple-select-users table="users"
username-field="user"
password-field="password"/ -->
<sql-select-users sql="select user,password from users where
user = ?" />
</database>
</authentication>
</security-realm>
<outbound-connections>
<database>
<connection driver="org.h2.jdbcx.JdbcDataSource"
name="db"
url="jdbc:h2:/tmp/test;DB_CLOSE_DELAY=-1" username="sa"
password=""
min-pool-size="10" max-pool-size="20" />
</database>
</outbound-connections>
Any suggestions how to solve this?
Thanks!

I found a solution to my problem. Had to update the xsd schema with an
extra attribute "module" and then user need pack his JDBC driver as module.
I use the code below to load the model and the driver class.
Class<?> driverClass =
Module.loadClassFromCallerModuleLoader(ModuleIdentifier.fromString(moduleName),
driver);
driverClass.newInstance();
<outbound-connections>
<database>
<connection module="com.h2database.h2"
driver="org.h2.jdbcx.JdbcDataSource" name="db"
url="jdbc:h2:/tmp/test;DB_CLOSE_DELAY=-1" username="sa"
password=""
min-pool-size="10" max-pool-size="20" />
</database>
</outbound-connections>
Does it make sense?
Thanks

The -ds.xml functionality uses the module through the <driver> tag, so
this would be similar.
Things to watch out for is of course the password attribute - it should
at least support the vault mechanism I would say.

If you make the attribute definition have expressions=true, it will
automatically enable vault support.

given that you use AD.parseAndSetParameter() when parsing and setting
field and
AD.resolveModelAttribute() when getting data from model

I had to do one more thing to make it work with the module class loader,
since the database driver was loaded in it's own class loader and it was
not known to the current class loader I had to find a way to make it
available
I solve it by wrapping the driver in my own class and register the driver
to the DriverManager
Like this :
DriverManager.registerDriver(new DatabaseDriverWrapper(driver));
DriverManager.getConnection(url, user, password);

I can't remember if I replied to this one or not, but a better solution
is to use the Driver class directly. We should avoid sticking random
things in the global registry which might even end up containing
conflicting values.

Jason,
Just so I'm sure I follow you, what you suggestion is solution like this,
right?
Properties cg = new Properties();
cg.put("user", user);
cg.put("password", password);
Connection conn = driverClass.connect(url, cg);

Hi
I'm trying to finish https://issues.jboss.org/browse/AS7-1371 but I
ran into a problem with the class loader. I need way to load the
class for a specified JDBC driver, but I can't seem to figure out
how to make it available on the classpath too my authentication service.
I try to load the connection class like this, and testing it with
the existing H2 JDBC driver:
ClassLoader original = null;
try {
original = Thread.currentThread().getContextClassLoader();
if (original != null) {
Thread.currentThread().setContextClassLoader(null);
}
Class.forName(this.driver).newInstance();
} finally {
if (original != null) {
Thread.currentThread().setContextClassLoader(original);
}
}
The user can setup a outbound connection to a database for
authentication, by using the configuration below
<security-realm name="ManagementRealm">
<authentication>
<local default-user="$local"/>
<database connection="db" plain-text="true">
<!-- simple-select-users table="users"
username-field="user" password-field="password"/ -->
<sql-select-users sql="select user,password from users
where user = ?" />
</database>
</authentication>
</security-realm>
<outbound-connections>
<database>
<connection driver="org.h2.jdbcx.JdbcDataSource"
name="db" url="jdbc:h2:/tmp/test;DB_CLOSE_DELAY=-1"
username="sa"
password="" min-pool-size="10" max-pool-size="20"
/>
</database>
</outbound-connections>
Any suggestions how to solve this?
Thanks!
