Hi there,
I am testing a CDO 4.1 server using a SSL connection. Everything went well with a simple TCP connection based on the example server. Currently the client connection test fails on server side due to an occuring java.nio.BufferUnderflowException.
Some details:
- CDO 4.1.1.v20120911-1146 (Juno SR1 release)
- Win x86_64 machine, Win7, Java7_09
To mention first, the NIO exception lets me think of an native problem within the 64bit enviroment, but I am not sure about that. I'm not very familiar with the Net4j interna. As far as I see, the SSL handshake works, but a read attempt fails afterwards.
What I've done so far:
- a CDO server based on the example master server (org.eclipse.emf.cdo.examples.installer.master) with a acceptor type "ssl"
<acceptor type="ssl" listenAddr="0.0.0.0" port="2036"/>
- created a keystore and truststore according to bug report https://bugs.eclipse.org/bugs/show_bug.cgi?id=333947 and modified the vmargs for launch
-Xms40m
-Xmx1024m
-Ddebug=true
-Dnet4j.config="${project_loc:/org.eclipse.emf.cdo.examples.installer.master}/config"
-Dorg.eclipse.emf.cdo.server.browser.port=7777
-Dosgi.console.enable.builtin=true
-Djavax.net.ssl.trustStore=file:///${resource_loc:org.eclipse.emf.cdo.examples.installer.master/ssl}/truststore.jks
-Djavax.net.ssl.trustStorePassword=truststore
-Djavax.net.ssl.keyStore=file:///${resource_loc:org.eclipse.emf.cdo.examples.installer.master/ssl}/keystore.test.jks
-Djavax.net.ssl.keyStorePassword=truststore
-Dorg.eclipse.net4j.tcp.ssl.passphrase=truststore
-Dorg.eclipse.net4j.tcp.ssl.trust=file:///${resource_loc:org.eclipse.emf.cdo.examples.installer.master/ssl}/truststore.jks
-Dorg.eclipse.net4j.tcp.ssl.key=file:///${resource_loc:org.eclipse.emf.cdo.examples.installer.master/ssl}/keystore.test.jks
-Dsun.security.ssl.allowUnsafeRenegotiation=true
-Dorg.eclipse.net4j.util.om.trace.disable=false
- enabled tracing
- created a test client connection with
// Enable logging and tracing
OMPlatform.INSTANCE.setDebugging(true);
OMPlatform.INSTANCE.addLogHandler(PrintLogHandler.CONSOLE);
OMPlatform.INSTANCE.addTraceHandler(PrintTraceHandler.CONSOLE);
// Prepare container
IManagedContainer container = ContainerUtil.createContainer();
Net4jUtil.prepareContainer(container); // Register Net4j factories
SSLUtil.prepareContainer(container);
CDONet4jUtil.prepareContainer(container); // Register CDO factories
container.activate();
// Create connector
IConnector connector = SSLUtil.getConnector(container, CDOTests.URL);
// Create configuration
CDONet4jSessionConfiguration configuration = CDONet4jUtil.createNet4jSessionConfiguration();
configuration.setConnector(connector);
configuration.setRepositoryName(CDOTests.REPO);
// Open session
CDOSession session = configuration.openNet4jSession();
session.options().setGeneratedPackageEmulationEnabled(true);
CDOTransaction cdoTransaction = session.openTransaction();
assert null!=cdoTransaction.getResourceNode("testResource"); //$NON-NLS-1$
session.close();
connector.close();

Hi Bernold,
The SSL connector has been developed by NoMagic and I'm not able to give advice for it. I've cc'ed Saulius from NoMagic
in the hope that he can provide more infos.
Cheers
