Obtaining client certificate in servlet using apache + tomcat

Hi,
I'm porting a webapplication from Javawebserver to Apache/1.3.6 (Win32) mod_jk mod_ssl/2.2.6 OpenSSL/0.9.2b
The application needs to get the client certificate hash code.
Using Javawebserver I used
request.getAttribute ("javax.net.ssl.cipher_suite");
request.getAttribute("javax.net.ssl.peer_certificates");
etc
How do I set up the apache webserver so that I can read the client certificate and what is the attribute called?
I've tried this in the httpd.conf:
SSLOptions +ExportCertData
And the attribute:
"SSL_CLIENT_CERT"
Like it says in the Tomcat documentation.
I'm not sure if I need to set up Tomcat as well..
Any help would be greatly appriciated!
Sincerely,
AM Hjemaas

Yup use ajp13 not ajp12 or mod_webapp
refer to http://www.galatea.com/flashguides/apache-tomcat-24-win32.xml on setting up..
THIS IS IMPORTANT!!!
use Apache mod_jk.dll diretive:
JkEnvVar Apache_Env_Var FORWARD_ALIAS
this will send a apache environment variable (http://myapache/cgi-bin/printenv.pl to see whats available) to Tomcat
JkEnvVar SSL_CLIENT_CERT SSL_CLIENT_CERT
Then in Tomcat servlet use request.getAttribute("SSL_CLIENT_CERT") to get the cert in PEM format
Hope this helps

Client Certificate Mapping authentication using Active Directory across trusted forests

Hi,
We currently have a setup where the on-premises environment and the cloud environment are based on two separate forests linked by a 1-way trust, i.e., the exist in the on-premises AD and the 1-way trust allows them to use their
credentials to login to a cloud domain joined server. This works fine with the Windows authentication.
We are now looking at implementing a 2-Factor authentication using Certificate. The PKI infrastructure exists in the On-Premises Forest. The users are able to successfully login to on-premise servers configured with "AD CLient Certificate
Mapping".
However, we are unable to achieve the same functionality on the cloud domain joined servers. I would like to know
1. Is this possible?
2. If yes, what do we need to do to make this work.
Just to clarify, we are able to authenticate using certificates by enabling anonymous authentication. However, we are unable to do the same after turning on "Client Certificate Mapping authentication using Active Directory"

1. Yes!
2. Before answering this I need to know if your are trying to perform a smart card logon on a desktop/console or if you just want to use certificate based authentication in an application like using a web application with client certificate requirements
and mapping?
/Hasain
We will eventually need it for smartcard logon on to desktop/console. However, at present, I am trying to use this for certificate based authentication on a web application.
To simulate the scenario, I setup up two separate forests and established a trust between them.
I then setup a Windows PKI in one of the forests and issued a client certificate to a user.
I then setup a web server in both the forests and configured them for anonymous authentication with Client SSL requirement configured.
I setup a test ASP page to capture the Login Info on both the servers.
With the client and the server in the same forest, I got the following results
Login Info
LOGON_USER: CORP\ASmith
AUTH_USER: CORP\ASmith
AUTH_TYPE: SSL/PCT
With the client in the domain with the PKI and the server in the other Forest, I got the following response
Login Info
LOGON_USER:
AUTH_USER:
AUTH_TYPE:
I tried the configuration with the Anonymous Authentication turned off and the AD CLient Certificate mapping turned on.
With the client and the server in the same forest, I am able to login to the default page. However, with the server in a trusted forest, I get the following error.
401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied

How to retrieve DN from client certificate in servlet

Hello,
My servlet has to use SSL, and authenticate users based on the owner of a client certificate.
Is there a way for my servlet to obtain the session's client certificate and extract the owner's DN from it?
Thanks!

Tomcat 3.3.2? That's a pretty darned old version. We're up to 5.0.x now. Time for an upgrade?
Yes, that's a CLASSPATH problem, because the TOMCAT_HOME/common/lib/servlet.jar should certainly be in the CLASSPATH. How are you running Tomcat? Do you use the startup.bat script, or is it installed to run as a daemon service? If it's the former, make sure the servlet.jar is in the script CLASSPATH. If it's the latter, make sure servlet.jar, bootstrap.jar, and tools.jar are added to the -D parameter java.class.path.

Problem connecting oracle database to jsp pages using Apache Tomcat server 8.0

My oracle is installed in the D: drive and tomcat in c:. i copied the ojdbc6.jar file from oracle to lib directory of tomcat server.
Then i set CLASSPATH in environment variables as "C:\Program Files\Apache Software Foundation\Tomcat 8.0\lib\ojdbc6.jar" in system variables
My path variable is set as "C:\Program Files\Java\jdk1.7.0_02\bin".
My program is as follows in notepad:

>> ODBC Driver Manager ... Data source name not found
That appears to be ODBC drivers looking for a DSN (Data Set Name). If it wants a DSN, the DSN has to be specified in the code, and the DSN has to be configured in the windows host ODBC applet. So that is at least two squirrels to get in the right tree before moving forward. A ...host:...[port:]SID|service name are some of the bits needed in a jdbc connect string, and that is in no way related to DSNs. A Whole Different Animal. If it wants a DSN that might be what needs to go in the URL bit.
And ODBC setups can be confusing, especially if an x64 OS is in the mix- if that is the case there are two different ODBC configuration applets, one for x64 the other for x86, and if one gets as far as talking to an actual database it might toss an architecture error. Only way to fix that "problem" is *delete* the ODBC DSN and then run the correct (maybe the x86) ODBC config utility, and set up the DSN. Again.

Java Servlet Setup Apache/Tomcat

How do I setup a CLASSPATH to a file called serverhub.jar in a folder. (ex. c:\javaclient/serverhub.jar)
Then I need to name the Servlet "hub" and give it a class name of com.peregrine.hub.HubServlet
Then I need to give it initialization arguments
servers=servername:6000
default=servername
threads=500
Can someone tell me where to setup these items for a tomcat jserver and an apache http server. I already have the jserver and apache server up and running.

You set this up under the TOMCAT_HOME/webapps/"servlet context"/WEB_INF directory. This directory should contain a classes directory, which contains your servlet class. It should also contain a lib directory, where you put the jar files. Finally, it should contain a web.xml file. This XML file is where you specify the servlet name, servlet class and initialization parameters.
You can follow the examples located in TOMCAT_HOME/webapps/examples or see http://jakarta.apache.org/tomcat/tomcat-3.2-doc/appdev/index.html

Servlet mapping with Apache + Tomcat

I'm trying to set up my servlet with apache + Tomcat(3.2.3), and i'm using mod_jk as the Tomcat-Apache plug-in.
The HelloWorld servlet that comes with the examples app worked fine at: http://localhost/examples/servlet/HelloWorldExample,
but how do I change the configurations, so that it can be invoked at:
http://localhost/examples/HelloWorldExample ?
It appears to me that '/servlet/' is the default prefix for Tomcat's RequestInterceptor, there is no way to get around that.
Any insights will be greatly appreciated, thanks!
Elaine

hi
Try this:
add below code in web.xml file in examples/WEB-INF
F directory
<servlet-mapping>
<servlet-name>
HelloWorldExample
</servlet-name>
<url-pattern>
/HelloWorldExample
</url-pattern>
</servlet-mapping>
Thanks for the reply, the web.xml is already set up this way, in fact, I'm able to invoke the servlet through tomcat(running on port 8080): http://localhost:8080/examples/HelloWorldExample,
tomcat reads the web.xml without any problems.
The problem comes from Apache(port 80), http://localhost:80/examples/HelloWorldExample wouldn't work, only http://localhost:80/examples/servlet/HelloWorldExample works.
It appears to me that when requests are relayed from Apache to tomcat, you need to tell tomcat that you intend to invoke a servlet by prefixing '/servlet/', if you look in the server.xml, it has
<RequestInterceptor
className="org.apache.tomcat.request.InvokerInterceptor"
debug="0" prefix="/servlet/" />
I've tried to change this to something else, it didn't seem to make any difference.

Problem using multiple Client Certificates

Hi folks, I had (mistakenly) posted an earlier version of this question to the crypto forum.
My problem is that I have multiple client certs in my keystore, but only one is being used as the selected certificate for client authentication for all connection�s. So, one connection works fine, the rest fail because the server doesn�t like the client cert being presented.
I have been trying to get the JSSE to select the proper client certificate by making use of the chooseClientAlias method. (init the SSL context with a custom key manager that extends X509ExtendedKeyManager and implements the inherited abstract method X509KeyManager.chooseClientAlias(String[], Principal[], Socket))
But, still no luck.. the JSSE is not calling in to the my version of chooseClientAlias, and it just keeps presenting the same client certificate.
No clue why, any thoughts on how to get the JSSE to call my version of chooseClientAlias?
Thanks!
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(createCustomKeyManagers(Keystore, KeystorePassword),
            createCustomTrustManagers(Keystore, KeystorePassword),null);
SSLSocketFactory factory = sslContext.getSocketFactory();
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
urlConn = (HttpsURLConnection) conn;
urlConn.setSSLSocketFactory(factory);
BufferedReader rd = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
     System.out.println(line); }
public class CustomKeyManager extends X509ExtendedKeyManager
    private X509ExtendedKeyManager defaultKeyManager;
    private Properties serverMap;
    public String chooseClientAlias(String[] keyType, Principal[] issuers, Socket socket)
        SocketAddress socketAddress = socket.getRemoteSocketAddress();
        String hostName = ((InetSocketAddress)socketAddress).getHostName().toUpperCase();
        String alias = null;
        if(serverMap.containsKey(hostName)){
            alias = serverMap.getProperty(hostName.toUpperCase());
            if(alias != null && alias.length() ==0){
                alias = null; }
        else {
            alias = defaultKeyManager.chooseClientAlias(keyType, issuers, socket);
        return alias;
.

Topic was correctly answered by ejp in the crypto forum..
namely: javax.net.ssl.X509KeyManager.chooseClientAlias() is called if there was an incoming CertificateRequest, according to the JSSE source code. If there's an SSLEngine it calls javax.net.ssl.X509ExtendedKeyManager.chooseEngineClientAlias() instead.*
You can create your own SSLContext with your own X509KeyManager, get its socketFactory, and set that as the socket factory for HttpsURLConnection.*

What is the option client certificate for user authentication used for?

Hi All,
I have to work on a FTPS - XI -SAP scenario.
I can see an option for client certificate for user authentication when security is enabled for the FTP adapter. what exactly is this option used for?
P.S: I went through sap help but couldnt quite understand.

Thanks a lot Mark.
So for a FTPS -> XI -> SAP scenario the following settings are required.
1. I have to create a certificate in Visual Admin for the XI server , send a csr to a CA and get it signed by them, and i have to add this to the ssl_service view.
2. I have to hand over the public key to the FTPS server & this key will be used for encryption of the file
the above 2 steps are mandatory.
If i choose to use the client certificate option , i have to get the client certificate from the FTPS server and add it into the TrustedCAs list. This certificate is just to imply that the client is what it claims to be.
Will this certificate be used for encryption?
To make it clear let me put it this way. The certificate created in the XI Server is used for encryption and also for ascertaining that the its what it claims to be.
The clients certificate option is used only to make sure that the client is what its claiming to be & this is not used for encryption?

Multiple Realms in Apache Tomcat

Sorry, if this is the wrong forum, but its the closest match i could find.
I am trying to run 2 servlets that use apache tomcat's j_security with a FORM login to authenticate clients. I would like these 2 servlets to be authenticated by having j_security look in two different tables in a MS SQL 2000 Server database.
I have read up a lot on apache tomcat's site, and the sense that i've made of it is that i need to have multiple realms, and in order to do that i need multiple contexts. I've tried wrapping my realm tag in a context tag but it doesn't work. What am i missing?
thanks.
<Context path="/servlet/" docBase="ROOT/WEB-INF/classes" reloadable="true" />
          <Realm className="org.apache.catalina.realm.JDBCRealm" debug="99"
     driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
     connectionName="sa" connectionPassword="******"
     connectionURL="jdbc:microsoft:sqlserver://localhost:1433;databaseName=ConcernCheck;selectMethod=cursor;"
userTable="Operator" userNameCol="Username" userCredCol="Password"
     userRoleTable="Operator" roleNameCol="Role" />
</Context>
Thanks

How to place a servlet file in Tomcat 5.0?

Hi,
i'm using Apache Tomcat 5.0 as myweb server.i don't know how to set the class path and where to place my servlet and html files,and how to run my servlet file.if anybody knows plz give me a detailed description abt this topic.

Look at the directory structure of your Tomcat installation directory. You will see a webapps directory under that. The Tomcat installation comes with samples ready to run. Look at those and create a similar directory structure under webapps for your application. I don't think you need to worry about classpath. Tomcat should be taking care of all that if you create the proper directory structure.
You run your servlet by specifying a url like:
localhost:8080/servlets-examples/from a browser. This assumes that your installation is using port 8080 which I think is the norm for Tomcat. Here "servlets-examples" is the name of the directory you created. Actually Tomcat 5.0 comes with a "servlets-examples" application. This would be a good directory to look at. You could also run their examples to get a feel for it.
If you are new to servlets, you'll probably have to get a book that explains how things need to be set up. You'll need to create a web.xml for your application. If you look at the servlets-examples directory under webapps, you'll see that it has a WEB-INF directory under it and that directory contains a file called web.xml as well as a sub-directory called classes. This structure is standard accross all application servers because it corresponds to the war (wars are specialized types of jars for web apps) file standard.

Maybe your web.xml is wrong. Doublecheck it.

How to install apache tomcat in nebeans

hello everyone,
i am not able to configure apache tomcat in my netbeans.
i am little bit confuse between apache tomcat and glassfish servers. can any one tell where we glassfish and where we use apache tomcat?

Tomcat is a 'servlet engine'; put as simple as I can make it, it is a Java webserver. You can create web applications based on servlets & JSPs and run them on Tomcat.
Glassfish is an Java Enterprise (JEE) server and provides an implementation for the full Java Enterprise Edition specification. This also includes servlets & JSPs, but on top of that you get a whole batch of additional services.
I would start with Tomcat if I were you. You don't need to configure anything, if you download the proper Netbeans bundle it comes with Tomcat 7 already setup. If that is not the case, you either picked the wrong bundle or you made wrong decisions during installation.
edit:
Question for you. Do you know anything about Java at all (since you are posting this in new to java)? If not then you are waaaaaaaay out of your league trying to get into web programming, it is complicated and confusing enough if you know Java, it is near impossible to understand if you don't even know the basics of the basics yet.

Apache Tomcat vs IBM Websphere

Hi,
In our current deployment, I am using Apache Tomcat as the Java Application Server that comes bundled with Hyperion Planning 9.3.1 suite of applications. The documentation also suggests Oracle Application Server, IBM Websphere and BEA WebLogic. Currently the application stack is Hyperion Planning only, with Financial Reporting for the reporting needs.
For our current situation, we have shortlisted between using the bundled Apache Tomcat or IBM Websphere. For comparison I wanted to know how stable Apache Tomcat is in general compared to websphere? How many concurrent users can it handle? Are there any specific limitations of Apache Tomcat that I should consider? Can someone list the major pros and cons of each?
Thanks in advance

I agree with Jake.. Tomcat can handle much more than a few users. Whether it can handle the load for your environment may depend on your usage pattern, size of forms, etc.
We typically use Tomcat for our Dodeca product that uses the Java API to talk to Essbase. It doesn't product 'forms' but rather just transfers data via XML between the client and server. With that product, we do have one customer that is serving appx 7,000 users on a single Tomcat server. In that case, however, the usage pattern is that field users log in daily (or sometimes weekly) and run a few reports (that retrieve data via XML).
Note that Tomcat has a configuration parameter in the server.xml file to set the max number of threads that can be spawned by the process. You may want to tune that parameter if you decide to run Tomcat in production (and absolutely be sure to give it more heapsize in the java options).
