Hello Experts.
Need some guidance.
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.
- Read this trust store as a stream (use getResourceAsStream method).
- Save it in any file on the client machine (sometemp)
- Call System.setProperty ("javax.net.ssl.trustStore", trustStorePath);
But I am sure there must be better solutions than this.. Any ideas to make it better?
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" };

Laz appreciate your patience, trying to learn when I get some time. 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?
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.
