    <p>Need some guidance. </p> <p>I have java webstart app and I want it to connect to a server via SSL.just adding a property like:System.setProperty("javax.net.ssl.trustStore","my.keystore");But since a JAWS program is downloaded from server didn't work and don't have a my.keystore on local file system. So decided to distribute the certificate to all clients.I did the following and it worked.</p> <ol> <li>Read this trust store as a stream (use getResourceAsStream method).</li> <li>Save it in any file on the client machine (sometemp)</li> <li>Call System.setProperty ("javax.net.ssl.trustStore", trustStorePath);</li> </ol> <p>But I am sure there must be better solutions than this.. Any ideas to make it better? </p> <pre><code>public boolean validateUserFromActiveDirectory(String userId) { final String MEMBER_GROUP = "CN=asdadasd,OU=asdasdasd Accounts,OU=adasdas,OU=asdasdas,DC=asdasdas,DC=asdasdas,DC=adasdasd,DC=asdasdasd"; String employeeNumber = ""; final String LDAP_INIT_CTX = "com.sun.jndi.ldap.LdapCtxFactory"; final String LDAP_URL = "ldap://xx-ssssssss.eee.eee.eeeee.eeeee:636"; final String MY_ATTRS[] = { "employeeNumber" }; String adminPassword = "somepassword"; String securityProtocol = "ssl"; boolean isValidUser = false; try { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, LDAP_INIT_CTX); env.put(Context.PROVIDER_URL, LDAP_URL); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.REFERRAL, "follow"); env.put(Context.SECURITY_PRINCIPAL, MEMBER_GROUP); env.put(Context.SECURITY_CREDENTIALS, adminPassword); env.put(Context.SECURITY_PROTOCOL, securityProtocol); //C:\Documents and Settings\yourusername\Local Settings\Temp File tf = File.createTempFile("someTruststore", ".jks"); tf.deleteOnExit(); byte buffer[] = new byte[0x1000]; ClassLoader cl = JNDI.class.getClassLoader(); InputStream in = cl.getResourceAsStream( "someTruststore.jks"); FileOutputStream out = new FileOutputStream(tf); int cnt; while ((cnt = in.read(buffer)) != -1) out.write(buffer, 0, cnt); in.close(); out.close(); System.setProperty("javax.net.ssl.trustStore", tf .getAbsolutePath()); DirContext context = new InitialLdapContext(env, null); SearchControls searchControls = new SearchControls(); searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE); NamingEnumeration results = context.search( "XX=ent,XX=abc,XX=aaaaa,XX=aaaa", "(sAMAccountName=" + userId + ")", searchControls); if (results != null &amp;&amp; results.hasMore()) { //some logic } } } catch (Exception e) { e.printStackTrace(); } return isValidUser; } </code></pre> <p>-Padur ===========================**=============</p> <pre><code>/** </code></pre> <p>* */</p> <pre><code>package util; /** * @author spaduri * */ import java.io.IOException; import java.net.InetAddress; import java.net.Socket; import javax.net.SocketFactory; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLSocketFactory; import javax.net.ssl.TrustManager; public class CustomSSLSocketFactory extends SSLSocketFactory { private SSLSocketFactory factory; public CustomSSLSocketFactory() { try { SSLContext sslcontext = null; // Call getKeyManagers to get suitable key managers KeyManager[] kms=getKeyManagers(); if (sslcontext == null) { sslcontext = SSLContext.getInstance("SSL"); sslcontext.init(kms, new TrustManager[] { new CustomTrustManager() }, new java.security.SecureRandom()); } factory = (SSLSocketFactory) sslcontext.getSocketFactory(); } catch (Exception ex) { ex.printStackTrace(); } } public static SocketFactory getDefault() { return new CustomSSLSocketFactory(); } public Socket createSocket(Socket socket, String s, int i, boolean flag) throws IOException { return factory.createSocket(socket, s, i, flag); } public Socket createSocket(InetAddress inaddr, int i, InetAddress inaddr1, int j) throws IOException { return factory.createSocket(inaddr, i, inaddr1, j); } public Socket createSocket(InetAddress inaddr, int i) throws IOException { return factory.createSocket(inaddr, i); } public Socket createSocket(String s, int i, InetAddress inaddr, int j) throws IOException { return factory.createSocket(s, i, inaddr, j); } public Socket createSocket(String s, int i) throws IOException { return factory.createSocket(s, i); } public String[] getDefaultCipherSuites() { return factory.getSupportedCipherSuites(); } public String[] getSupportedCipherSuites() { return factory.getSupportedCipherSuites(); } protected KeyManager[] getKeyManagers() throws IOException, GeneralSecurityException { // First, get the default KeyManagerFactory.

I started writing my own CustomSSLSocketFactory..right now I am bypassing security...based on the example by platinum solutions.If I do that ...will the information pass as a clear text on the network?</p> <p>Now I wonder what should I do with the truststore file I am having "sometruststore.jks" file. What should I do with that ..Do I have wrie my own custom trustmanager software ? Please guide me in correct direction.</p> <p>-padur</p>

    1. COThe information will not be clear text. It will be encrypted, but not authenticated since this code considers all certificates to be trusted. You don't have to write your own trustmanager to handle the .jks file. Take a look at my answer below and see that you can pass a KeyStore instance to to the SSLSocketFactory subclass. You can get that instance in the same way you are in your original code by loading if off of the classpath.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
