Multiple problems with ServerInvokerServlet and HttpNamingCo
Hi experts of remoting!
My configuration is as follows:
I use JBOSS 4.2.2 GA (EJB3). A remote client (RCP) communicates with the server via the ServerInvokerServlet.
Basically everything works fine and the response time is very good.
Here an example how I connect to the server:
// Initialize initial context
Hashtable env = new java.util.Hashtable();
env.put(InitialContext.PROVIDER_URL, "http://myhost:8080/invoker/JNDIFactory");
env.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.HttpNamingContextFactory");
env.put(InitialContext.SECURITY_PRINCIPAL, "user");
env.put(InitialContext.SECURITY_CREDENTIALS, "password");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
try
{
ctx = new InitialContext(env);
}
catch (NamingException e1)
{
e1.printStackTrace();
}
ctx.lookup(...)Well, as I said it works basically. But I have some further demands, that I haven't been able to implement yet.
1. Security
The application I deploy on the server uses a simple log-in module, witch works great when I use RMI as transport protocol.
If I use http as transport I get an error message that the user name is null!
What do I have to configure to get this working?
2. Exeption handling
Due to a bug in JBOSS remoting I downloaded the latest version of remoting in order to catch remote exceptions on my client. The tutorials say that there is a client-side switch: NO_THROW_ON_ERROR.
Where do I have to set this command within my configuration?
3. Compression
I want to compress traffic between server and client. On the server side I use following configuration:
<mbean code="org.jboss.remoting.transport.Connector"
name="jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3">
<depends>jboss.aop:service=AspectDeployer</depends>
<attribute name="Configuration">
<config>
<invoker transport="servlet">
<attribute name="serverBindAddress">${jboss.bind.address}</attribute>
<attribute name="serverBindPort">8080</attribute>
<attribute name="path">servlet-invoker/ServerInvokerServlet</attribute>
<attribute name="marshaller" isParam="true">org.jboss.remoting.marshal.compress.CompressingMarshaller</attribute>
<attribute name="unmarshaller" isParam="true">org.jboss.remoting.marshal.compress.CompressingUnMarshaller</attribute>
</invoker>
<handlers>
<handler subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler>
</handlers>
</config>
</attribute>
</mbean>At the moment I get an error message when I try this configuration on my server telling me that the header is not in GZIP-format.
What do I have to do here on my client to use compression successfully?
Thank you very much in advance!!
