Disabling certificate validation in Java

In case you need to disable validation of certificate here is Java snippet.

 import javax.net.ssl.*;  
 import java.security.SecureRandom;  
 import java.security.cert.X509Certificate;  
 public static void disableCertificateValidation() {  
  // Create a trust manager that does not validate certificate chains  
  TrustManager[] trustAllCerts = new TrustManager[] {   
  new X509TrustManager() {  
   public X509Certificate[] getAcceptedIssuers() {   
   return new X509Certificate[0];   
   }  
   public void checkClientTrusted(X509Certificate[] certs, String authType) {}  
   public void checkServerTrusted(X509Certificate[] certs, String authType) {}  
  }};  
  // Ignore differences between given hostname and certificate hostname  
  HostnameVerifier hv = new HostnameVerifier() {  
  public boolean verify(String hostname, SSLSession session) { return true; }  
  };  
  // Install the all-trusting trust manager  
  try {  
  SSLContext sc = SSLContext.getInstance("SSL");  
  sc.init(null, trustAllCerts, new SecureRandom());  
  HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());  
  HttpsURLConnection.setDefaultHostnameVerifier(hv);  
  } catch (Exception e) {}  
 }  

I took code from here: Java client certificates over HTTPS/SSL

Getting mail.box from Domino server

Domino allows to setup up to 10 mail boxes for 1 server. By default it 1 mail box with name mail.box however if you increase number of mail boxes to 2 and more Domino will create mail1.box, mail2.box ... and you must remember about it.

In order to get mail box without doing lookup to ServerConfig document, just try to initiate mail1.box first and if it does not exists go for mail.box

public Database getMailBox(Session session) throws NotesException{
 String server = session.getServerName();
 Database mailbox = session.getDatabase(server, "mail1.box");
 if (!mailbox.isOpen()) {
  mailbox = session.getDatabase(server, "mail.box");
 }
 return mailbox;
}

There is topic on how to force Domino to use mail.box when multiple mail.boxes are enabled

Domino and No trusted certificate found

We have few agents that communicate with other systems via and today at 13:00 we got such answer from Domino when we tried to set connection with external system. That was a huge problem for us since it affect our business.

It took some time to fix it, but here is a solution

Problem

A Java application running on a Domino server connecting over SSL to another server may require having the SSL certificate authority of the other server imported into its JVM.

Symptom

When a Java application running on a Domino server connects over SSL to another server, but does not have that server's trusted root certificates, an error may occur. One example of such an error is: HTTP JVM: javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.g: No trusted certificate found.

Cause

The trusted root certificates that signed the remote server's SSL certificate must be also be trusted by the Domino server's JVM if a Java application is making an SSL connection.

Resolving the problem

To add the trusted root certificates to a Domino server JVM follow these steps:

A. Obtain the Certificate to be Imported

Each browser displays certificates in different ways, but they are usually quite similar. On the browser's URL bar, there is usually a zone that you can click on to display SSL certificate information. For example, you may see a padlock in the status bar, and clicking on the padlock opens the certificate information. Once the certificate information is open, click on the "Certification Path" informatino. There normally will be a way to export each of the signing certificates (trusted roots). Export the certifiers in the "Base-64 encoded X.509 (.CER)" format. The exported file in this format will be an ASCII text file that has "BEGIN CERTIFICATE" and "END CERTIFICATE" lines at the top and bottom. Once you have exported the certificates that signed the remote server's SSL certificate you can then import them into the JVM.

B. Import the SSL certifier into the JVM.

If Domino is on a UNIX server, perform these steps on a Windows workstation, and then move the cacerts to the server after the import is completed.

Import the SSL Certificate into the JVM using these steps:

• Open a command line and change directory to C:\Lotus\Domino\jvm\bin.
• Run the batch file "IKEYMAN.exe" (a Java application will load).
• Click "Key Database File" then "Open".
• Browse to C:\Lotus\Domino\jvm\lib\security\cacerts. Note, you will have to view "All Files" to locate cacerts.
• Supply the default password of "changeit". Note, consult your administrator if you receive an error pertaining to the password.
• Select "Signer Certificates" in the drop-down menu.
• Click "Add"
• Select "Browse" and locate the .CER file you copied.
• Click "OK" and enter a descriptive label.
• On the Domino console issue the command "restart task http".

Issues when developing IBM Domino Notes applications

Some minor stuff about Domino Designer.

• Undo/'Ctrl+Z' does does not work properly when you developing in Lotus Script, if you do it few times it might mess your code
• 'Ctrl+C'/'Ctrl+V' sometimes does not work from first attempt, so you need to do it twice
• 'Ctrl+C'/'Ctrl+V' sometimes it sets focus on penultimate character so you have to do 1 extra actions to continue write code
• I still have crashes in Domino Designer without any reasons and I've no customization to my Designer
• I'm not happy about speed in Designer, however maybe I expect to much

It is 2013 and Ctrl+Z still work odd, how could it be?
Do you have something to add to that list? :) Please - comments about that!

IBM Designer Java Console effect?

I've faced up with interesting problems. I'm doing integration between MailChimp and Domino application. MailChimp service has very good API so it was not huge problem to push/poll data to/from it and we already implemented solution based on Java. The fun started when I tried to do LS2J part. My first request to java method came up with this dialog

That error does not happen if I enable Java Console in IBM Domino Designer. When Console is up - everything works perfect, otherwise this error:

LS2J Error: Threw java.lang.SecurityException: not allowed to access members in class interface java.util.Map

I can't explain how Java Console affect my security level, however definitely it does. I think it possibly grant users with more access when it is running and maybe there is an explanation why. Does anybody of you can explain that?
