Hello,

I get a strange exception in my OPC UA Client:

java.lang.NullPointerException
at org.opcfoundation.ua.transport.UriUtil.getSocketAddress(Unknown Source)
at org.opcfoundation.ua.transport.UriUtil.getSocketAddress(Unknown Source)

at com.prosysopc.ua.client.UaClient.connect(Unknown Source)
at de.spektra.infraview.conformance.OpcUaTestSuite.connect(OpcUaTestSuite.java:216)

It doesn’t show up every time i try to connect, but very often. My code looks like this:

destClient = new UaClient(url);
final PkiFileBasedCertificateValidator validator = new PkiFileBasedCertificateValidator();
destClient.setCertificateValidator(validator);
ApplicationDescription appDescription = new ApplicationDescription();
appDescription.setApplicationName(new LocalizedText(APP_NAME,
Locale.ENGLISH));
appDescription
.setApplicationUri(“urn:localhost:spektra.com:infraview:OpcUaClient”);
appDescription.setProductUri(“urn:spektra.de:infraview:OpcUaClient”);
appDescription.setApplicationType(ApplicationType.Client);
final ApplicationIdentity identity = ApplicationIdentity
.loadOrCreateCertificate(appDescription, “spektra”,
null, //Private Key Password
new File(“”, “private”), //Key File Path
true); //Enable renewing the certificate
destClient.setApplicationIdentity(identity);
destClient.setLocale(Locale.GERMAN);
destClient.setTimeout(1000 * 60 * 2);
destClient.setSecurityMode(SecurityMode.NONE);
destClient.setUserIdentity(null);

destClient.connect();

The NullpointerException appears at the destClient.connect() command. Any help would be appreciated.

Felix
