I am trying to create a Application Identity to connect to a OPC server using Basis254SignandEncrypt with a username and password Authentication. I get this IO Exception
java.io.IOException: The filename, directory name, or volume label syntax is incorrect
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.createNewFile(Unknown Source)
at com.prosysopc.ua.stack.utils.FileUtil.writeFile(SourceFile:116)
at com.prosysopc.ua.stack.transport.security.Cert.save(SourceFile:194)
at com.prosysopc.ua.ApplicationIdentity.loadOrCreateKeyPair(SourceFile:632)
at com.prosysopc.ua.ApplicationIdentity.loadOrCreateCertificate(SourceFile:466)
at com.prosysopc.ua.ApplicationIdentity.loadOrCreateCertificate(SourceFile:358)
My code looks like this
certStore = new PkiDirectoryCertificateStore();
validator = new DefaultCertificateValidator(certStore);
client.setCertificateValidator(validator);
validator.setValidationListener(validationListener);
// *** Certificates
privatePath = new File(certStore.getBaseDir(),”privatefile”);
privatePath.canWrite(); // return a true to show that the directory is writable
privatePath.getAbsolutePath();// returns the correct path to the file
int[] keySizes = new int[] {0,4096};
Set supportedHttpsModes = new HashSet();
supportedHttpsModes.addAll(HttpsSecurityPolicy.ALL_102);
supportedHttpsModes.addAll(HttpsSecurityPolicy.ALL_103);
supportedHttpsModes.addAll(HttpsSecurityPolicy.ALL_104);
client.getHttpsSettings().setHttpsSecurityPolicies(supportedHttpsModes);
client.getHttpsSettings().setCertificateValidator(validator);
// Define a custom certificate validator for the HTTPS certificates
applicationDescription = new ApplicationDescription();
applicationDescription.setApplicationName(new LocalizedText(Applicationidentity + “GKNAerospace”));
applicationDescription.setApplicationUri(“urn:” + APPLICATIONURI + Applicationidentity);
applicationDescription.setProductUri(“urn:” + PRODUCTURI);
applicationDescription.setApplicationType(ApplicationType.Client);
try {
ApplicationIdentity.loadOrCreateCertificate(applicationDescription, “opcclient”, “opcclient”, privatePath, null, keySizes,true);
} catch (SecureIdentityException | IOException e) {
e.printStackTrace(); // I get error at this point
}
What is the problem ?

Hello swaj!
The certificates are stored to PKI\CA folder of your working directory by default. Could you verify that your working directory allows you to write files into it? Alternatively, you can try to initialize PkiDirectoryCertificateStore with an absolute path, e.g. “C:\\Folder1\\Folder2\\PKI”, of a folder that allows writing files into it.

Hello Matti Siponen
I tried to verify that I have user rights by actually writing a file using a another Java program into the same folder. The error I get still exists.

Hello swaj!
This exception could also be caused by attempting to write a file with filename containing invalid characters. In Windows based systems these invalid characters are , :, “, /, \, |, ? and *. Please verify that your Applicationidentity used to set application name doesn’t contain any of these characters.

This is the path I use
File privatePath = new File(“C:\\Users\\Admin\\Desktop\\certs\\privatefile”);
I can write to a file using the same path by using the java.io.fileWritter. Problem still exists !!!!!
Thank you

There should be no problem with your path. However, if your Applicationidentity contains invalid characters, it will cause this exception. Please specify the value of Applicationidentity used in the following line of the code:
applicationDescription.setApplicationName(new LocalizedText(Applicationidentity + “GKNAerospace”));
