JNDI using SSL hangs on multiple connections

Hi *,
I have read several topics in this forum but nobody responds, will be that somebody has solved this?
http://forum.java.sun.com/thread.jspa?forumID=51&threadID=539143
If I establish a SSL connection without credentials (anonymous) and change soon the credentials, the application hangs.
The same it happens if I do it on the contrary (first with credentials and soon without these).
And finally, the application also hangs if I use multiple SSL connections.
I'm lost :-)
Anticipated thanks

Brainstorming with a co-worker solved the problem. A graphic I was using was too large for InDesign to handle on the multiple document data merge. So I reducd the file size, and that did the trick.

Shall I use one datasource for multiple connection pool?

Hi,
I need to clarrify that, Shall I use one Datasource for multiple connection pool in distributed transaction?
Thanks with regards

No. If its transactions across multiple databases you should use different datasources.

Some RST are seen during TCP disconnection when using SSL connection

Some RST are seen during TCP disconnection when using SSL connection
It is expected that the disconnection sequence for a secure connection to be as follow:
client ************************* server
--- alert (warning, close notify) --->
<--- alert (warning, close notify) ---
in any order;
and then:-
--------------- FIN, ACK ------------>
<----------- FIN, ACK ---------------
------------------ ACK ----------------->
Instead of the sequence described above, the TCP connection for a secure connection is closed with an RST.
For instance, Wireshark capture shows that an SSL+SASL TCP connection is closed in the following manner:
client ************************** server
--- alert (warning, close notify) ---->
---------------- FIN, ACK ------------>
<--- alert (warning, close notify) ---
<----------- FIN, ACK ---------------------
------------ RST -----------------> *(This RST message should be investigated, an ACK message was expected)*

I agree it should be an ACK not an RST but it doesn't really matter. The connection is closed, and as neither the client nor the server has any pending data it is benign. Worth investigating in a later JRE.

Cannot download a file with internet explorer 6 using SSL connection

Hello,
I am working on a application that uses SSL. But when the clicks a button to donwload a file using IE 6 or IE 7, internet explorer shows a error message saying that "The internet explorer cannot open this site". This error dont occur in Firefox, but i have to use Internet Explorer. And the error occurs only if i use https, with http it works fine.
I search the net and i found that internet explorer has a bug, that when the server sends the http header "Pragma: no-cache" or "Cache-control: no-cache,max-age=0,must-revalidate", then the internet explorer doesnt cache the file, and i cannot open it. See here: http://support.microsoft.com/kb/316431/en-us
My problem is that OC4J appears to send this headers automatically. I am using Oracle Enterprise Manager 10g Application Server Control 10.1.3.3.0. Here, is my code to send the file:
HttpServletResponse response = (HttpServletResponse)
FacesContext.getCurrentInstance().getExternalContext().getResponse();
response.setContentType("application/x-download");
response.setHeader("Content-Disposition", "attachement; filename=\"file.pfx\"");
response.setContentLength((new Long(myFile.length())).intValue());
OutputStream out=null;
try {
out = response.getOutputStream();
fis = new FileInputStream(myFile);
int n;
while ((n = fis.available())> 0) {
b = new byte[n];
int result = fis.read(b);
out.write(b, 0, b.length);
if (result == -1) break;
out.flush();
out.close();
} catch (Exception e){
throw new DownloadException("Erro ao enviar arquivo para o stream de download.");
finally{
FacesContext.getCurrentInstance().responseComplete();
You can see that i not send that headers in this code.
Here, is the headers sent to IE when i use https.

Hi!
I don't have a solution fou you, just a few ideas =)
You can check what headers response contains with
response.containsHeader( "your_header_here");
http://java.sun.com/j2ee/sdk_1.2.1/techdocs/api/javax/servlet/http/HttpServletResponse.html#containsHeader(java.lang.String)
after that you could set/overwrite those headers that you don't like with, for example:
response.setHeader("Cache-control", "no-cache,max-age=0,must-revalidate");
Aparently Pragma and Cache-control headers should be used in pair, as noted here
http://curl.haxx.se/mail/archive-2005-12/0003.html
quote:"The author of Bad Behavior points out that RFC2616 requires that a
Pragma: header to be accompanied by a Cache-Control: header. From what I
see, it only says "SHOULD" (in section 14.32), but that is still a
strong recommendation and something to be considered, IMHO."
I'm a bit sceptical about you needing to cache the file, but if you feel strong about it, you could read this
http://www.mnot.net/cache_docs/#META
If you're working on SSL there is supposed to be some kind of validation, certificate or something like that. IE6 and 7 both have strong security measures in these regards. Maybe you should look something up in that direction.
Hope I helped.

Problems with connecting to MacOS X Snow Leopard Server using SSL

I can successfully connect to my SL mail server if I do not enable SSL, but if I do enable SSL the iPhone mail client just fails to connect with a message "Cannot Get Mail - The connection to the server "servername" failed". I have set SSL to ON in Mail preferences, but I cannot see how to install the server's certificate. With most mail clients it seems like the server's certificate gets installed the first time you try and retrieve mail, but this does not happen with the iPhone.
The reason I am having to switch SSL on is that I have a number of PC mail clients, and it does not seem as if any of the various versions of Outlook support any form of authentication other than plain text (except NTLM or SPA, which are not supported by MacOS X Server, probably because they are MS proprietary). So I think I will probably have to fall back to a plain text login, but using SSL to secure the process.
Excuse me if I have misconstrued any aspect of this, but it is based on what I have been able to trawl up so far in an extremely under-documented area.
I have looked at the iPhone documentation but it is very sketchy in the area of SSL implementation. For example the iPhone User Guide just says "To adjust SSL and password settings, tap Advanced. Ask your network administrator or Internet service provider for the correct settings."

Thanks for the suggestion, but the question is really to do with how to get an SSL certificate onto an iPhone since the normal way of doing this with an email client doesn't happen.
I have posted a reply in a thread in the SL Server section regarding the best way to cope with Outlook clients, which is the question the other way around. Essentially what I need is one form of secure authentication which works for both iPhones and Outlook - and this doesn't seem to be possible on the basis of my experience so far.
So back to my question - how do you connect from an iPhone to a mail server which requires SSL?

Connecting Using SSL Authentication Without Username and Password

Hi,
We're on RedHat Linux 4.0 using 10.2.0.3 (server/client). We're trying to figure out a way to connect to the database using instantclient and JDBC-OCI and SSL authentication without using a username or password. According to the documentation this should be possible but no sample code is given.
LD_LIBRARY_PATH is set /opt/app/oracle/product/10.2.0/db_1/lib:/usr/lib:/home/oracle/instantclient where the instantclient was installed from the 10.2.0.1 client software
and we are using JDK version 1.6.0_03.
We're also referencing the following paper:
http://www.oracle.com/technology/tech/java/sqlj_jdbc/pdf/wp-oracle-jdbc_thin_ssl_2007.pdf
We've got our client and server wallets configured and the sample code we tried looks like this:
import java.sql.*;
import java.sql.*;
import java.io.*;
import java.util.*;
import oracle.net.ns.*;
import oracle.net.ano.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.*;
import java.security.*;
import oracle.jdbc.pool.OracleDataSource;
public static void main(String[] argv) throws Exception {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Security.addProvider(new oracle.security.pki.OraclePKIProvider());
System.setProperty("oracle.net.tns_admin", "/opt/app/oracle/product/10.2.0/db_1/network/admin");
String url = "jdbc:oracle:thin:@orcl";
java.util.Properties props = new java.util.Properties();
props.setProperty("oracle.net.authentication_services","(TCPS)");
props.setProperty("javax.net.ssl.trustStore",
"/opt/app/oracle/product/10.2.0/db_1/admin/wallet/server/cwallet.sso");
props.setProperty("javax.net.ssl.trustStoreType","SSO");
props.setProperty("javax.net.ssl.keyStore", "/opt/app/oracle/product/10.2.0/db_1/admin/wallet/client/cwallet.sso");
props.setProperty("javax.net.ssl.keyStoreType","SSO");
props.put ("oracle.net.ssl_version","3.0");
props.put ("oracle.net.wallet_location", "(SOURCE=(METHOD=file)(METHOD_DATA=(DIRECTORY=/opt/app/oracle/product/10.2.0/db_1/admin/wallet/client)))");
System.out.println("At Here...");
OracleDataSource ods = new OracleDataSource();
//ods.setUser("scott");
//ods.setPassword("tiger");
ods.setURL(url);
ods.setConnectionProperties(props);
System.out.println("At Here1...");
Connection conn = ods.getConnection();
System.out.println("At Here2...");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select 'Hello Thin driver SSL "
+ "tester ' from dual");
while (rset.next())
System.out.println(rset.getString(1));
rset.close();
stmt.close();
conn.close();
When this code is compiled and run, the following error is thrown:
Exception in thread "main" java.sql.SQLException: invalid arguments in call
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
If a username and password is supplied, the code works. So does anyone have a working of using SSL to authenticate without supplying username/password?
Thanks
mohammed

Hi,
I just solved this. I noticed from another thread that I was not using the OCI driver (see below):
String url = "jdbc:oracle:thin:@pki14";
Once I changed it to:
String url = "jdbc:oracle:oci:@pki14";
The code worked perfectly. One more setting that you'll have to do is to create the user you want to connect as externally:
create user scott identified externally as
'CN=acme, OU=development, O=acme, C=US';
grant connect,create session to scott;
Note that the DN should be the same as the SSL certificate that you created in your wallet.

Is there any way to config iws6.0 to connect to LDAP directory using SSL client and server authentication. Only SSL server authentication worked when I tried.

As my previous question, I followed the following instructions to setup up connection between iws and an LDAP server.
"Using SSL to Communicate with LDAP
You should require your Administration Server to communicate with LDAP using SSL. To enable SSL on your Administration Server, perform the following steps:
1.Access the Administration Server and choose the Global Settings tab.
2.Click the Configure Directory Service link.
3.Select Yes to use Secure Sockets Layer (SSL) for connections.
4.Click Save Changes.
5.Click OK to change your port to the standard port for LDAP over SSL. "
Q1. Any other steps needed to setup client authentication (or mutual authentication)?
Q2. Do I need to enable security for connection groups in order to have this setup to work?

Check out:
http://docs.iplanet.com/docs/manuals/enterprise/60sp1/ag/esecurty.htm#1008113
You will need to turn on Client Auth as described above. Hope it helps.

When I try to set up my Optimum account email I get a message saying Cannot Connect Using SSL.

When I try to set up my Optimum email account I get an error message saying Cannot Connect Using SSL.

What mail provider is it?
Have you Googled for: setup XXX email on iPhone

You can try going to Mail>the accounts>Advanced and turn Use SSL on or off, the opposite of what it is now.

Does the 'Hotmail' option in IOS mail use SSL to connect to the hotmail servers?

Just wondering, when selecting the 'Hotmail' option when setting up email on IOS mail, whether this automatically uses SSL to connect to the hotmail servers - it doesn't show any server settings when you view the account.

Hi Drewscussions,
Thanks for the reply - I'm just wondering about the security measures in place behind those predefined settings I.e. does it use an encrypted SSL link. I would like to ensure, as I often access emails off public wifi, that I have it set correctly to use an encrypted connection to my hotmail account.
My emails have been working fine - it's more of a question about what security measures are in place in that preset mail option.
Cheers

Connect Adobe Drive to CQ 5.5 using SSL

I recently changed my CQ 5.5 server to use HTTPS (SSL) to connect to it so that it could be accessible from outside our network securely. The browser URL works fine using SSL and the new port, but now Adobe Drive won't connect. CQ Support told me to contact Adobe Drive Support, but I can't find that anywhere.

What is the behavior you're seeing with regard to Adobe Drive not connecting to your CQ 5.5 server? Are you using the latest version of Adobe Drive (related to Hema's question)? Recently released; Adobe Drive CC (compatible with CS6 and CC desktop applications). Is your CQ 5.5 server using a trusted certificate?
Overall, can you please send to me the case number that was provided to you when you contacted CQ support about this issue? I'll have an agent reach back out to you.

How to use multiple connections for xcelsius dashboard via toggle button

Can anyone shed some light on how to apply a toggle button for multiple connections using xcelsius dashboard.
I created two SAP connections in my xcelsius dashboard. The first connection uses query 1 (bottom ten customers) and the second connection uses query 2 (top ten customers). I wanted to use a toggle button where the user would click Top Ten customers versus Bottom Ten customers. Which ever the user clicks in the toggle botton would run that query.
If the toggle button is not the way to handle this can someone explain a better approach to run either query in the same dashboard.
Thanks,
Joe

Hi,
I've never had to do this so have no practical experience. However in theory you should be able to do the following (assuming the data connection type youu2019re using has the "Usage" tab):
Set up the two connections as normal - On the usage tab set the detail query to Refresh before components are loaded and make sure that this is unchecked for the other query. Set both queries to populate the same range so that one query will overwrite the other in the Xcelsius spreadsheet.
Bind a toggle button to a cell e.g. A1
Back to the data connections again and set the "Refresh on trigger" trigger cell to A1. And set the "When Value Becomes" to either "On" or "Off" dependent on how you've set up the toggle button. Repeat for the other query.
Hope this helps,
Paul

No idea how to do anymore. Already tried to figure out. But not work. Can anyone pls help me?

Nope, doesn't pass verification. I get the spinner for a minute or so, then the alert about setting it up without SSL. Are you suggesting I disable Fetch and Push BEFORE I enter the account details? Because I never get past the account details screen, unless I choose "Set up without SSL" after the warning.
