Browser authentication from client program
How is it possible to authenticate a browser from a client program? For example, how does the small "mail" icon in yahoo messenger open up a browser, then authenticate it against yahoo.com and display the email Inbox? Do browsers provide some API through which this kind of authentication is possible? Any insights in this direction would be greatly appreciated.
Thanks
Karthikeyan,
The error message says it all: feature is not supported.
For your information, your question has been asked (and answered) several times previously in this forum. Did you try searching the forum archives?
Personally, I just live with this limitation -- it's not critical for me. Have you tried the MetaLink Web site?
Good Luck,
Avi.

OS Authentication from Java Program
We are getting the below error while trying to get oracle connection using OS authentication.
from the unix shell, we are able to "sqlplus /" . ie., invoke a sqlplus session using / account
java.sql.SQLException: ORA-01004: default username feature not supported; logon denied
echo $TNS_ADMIN
/data/oracle/product/8.1.7.4/network/admin
We gave the below options
Option 1:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:oci8:@database","","");
Option 2:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:oci8:/@database");
However when substituted with actual user id and password the connection works
conn = DriverManager.getConnection("jdbc:oracle:oci8:@database", user , password);
The 8.1.7.4 oracle client is installed and am using classes12.jar of oracle8i version
Can you pls. helpKarthikeyan,

Reading files from clients machine through a browser
if i have to access or use some files say C:\hello\myimage.jpg from client machine's local drive, how it can be done using some technology in Java eg applets or some other way. please read the following situation to have a better undertsanding of the problem,
consider the following situation:
a web application is running on client PC, and on click of a button, i have to generate a report in some format and insert some images in that report which are on clients local drive and their path is known to me say C:\ myimage.jpg.
if the mages were on the server(where web application is hosted), then its not a prob.
if there any other technology in java to read files from clients PC through a browser other than javaSign the applet.

Could not browse pages from IIS after re-installation of Oracle client
Hi all,
Unfortunately, I hit a issue today in the morning. I could not browse pages from IIS after I re-installed my oracle client on my machine. Below is the error massage from browser.

When I comment a line for OracleWebEventProvider in health monitoring providers in machine.config, it works fine for me. But, Im wondering what went wrong during re-installation and how do I rectify this issue with out a temporary workaround.
Please let me know your suggestions in this regards and thanks for the help in advance.

KumarAfter I ran the "uninstaller" on the Oracle CD .. there were services still in existance, however, once I deleted the c:/Oracle folder, they were gone. I also re-booted the pc and double-checked, before I tried re-installing.
Thanks !

Hi,
look into services, is there any services is still exist or running with the same name.
or give any other SID which you have given previously.

I heard somebodies are developing solutions to do RMI from client browser,
is this a good idea?The Limitations of RMI Applets on the Internet
Although using RMI in Internet-based applets seems like a good idea, in practice, the instability of Internet connections and a lack of client support make it impractical. Among the obstacles to deploying RMI applets on the Internet are the following:
* Despite supporting the majority of the Java 1.1 specification, the most popular web browsers -- Netscape Navigator and Microsoft Internet Explorer -- do not adequately support RMI. Navigator supports RMI on most platforms but does not support HTTP tunneling, so Netscape users connected to the web through a proxy server can't use an RMI applet. Meanwhile, Netscape for the Macintosh does not support RMI at all. Internet Explorer 4.0-5.0 also lacks RMI support, although a patch is supposedly available to add the missing classes (the RMI classes are available from Microsoft's web site, but instructions for installing them is not provided). As a result, a large percentage of Internet surfers can't use RMI applets in their current browser.
* The RMI registry can experience problems when handling connections via the Internet. A bug that causes the registry to stop accepting new connections occurs all too frequently with web-based RMI clients, requiring that the registry be shut down and restarted. Also, in Java runtime environments prior to JDK 1.2.2, server sockets created to handle connections from Internet-based RMI clients can live on indefinitely (consuming server resources) even after those clients are shut down.
* The RMI registry is not as flexible as most server applications, answering only to client connections made to one specific hostname. This means that your RMI server application cannot support multiple domains on a single web server, which limits your deployment options.
* Many applications may require that data exchanged between client and server be encrypted, compressed, or handled in some other fashion. Doing this with RMI is simple enough, requiring only that you implement your own socket classes and an RMI socket factory that creates your special sockets. However, overriding the default socket factory disables RMI's ability to do HTTP tunneling, thereby preventing access by proxy server users.
* Deploying an RMI server application requires additional network firewall configuration. By default, RMI objects are bound to random, "anonymous" server port numbers, making it impossible to predict the ports that must be available to Internet clients. RMI functionality new to Java 2 allows you to specify a port number when creating a remote object, but deployment still requires that firewalls allow access to ports not typically used by web-based applications.

AND when u get the sample code working, tell me how u did it. okay? :) thx! mail me at [email protected]. -
It worked fine until 6 days ago - then the machine suddenly could not access the gmail account. Accessing gmail from browser or from Thunderbird on ANOTHER machine works fine.
Using IMAP and ssl.
I can see this problem has many treads on the web - so it should be known to Mozilla.
RegardsLots of thread on the web about "This problem" very few solutions though or you would not be here.
The usual cause is anti virus or firewall. Which is why solutions are thin on the ground. Have you tried starting windows in safe made with networking? and then starting Thunderbird -
Copy file from client PC to server in a web deployed application
I have developed one application using Oracle forms 6i, which is deployed on the web server.
I run this application from a client PC in Internet Explorer using internet.
I want to copy one file from the client PC to the web server.
I have done following things
- Created a shared folder on the server and given full rights to every one on this folder
- I use 'net use' command in my program to connect to this shared folder
- I use copy command to copy file from local client pc to server. This copy command I am executing using host command of my programming (PL/SQL: eg. host('copy abc.txt \\server\share\') )
But this does not work.
When I do the same thing in command window, it works.
(ie. Start-Run cmd to open command window and then type the above copy command)
Can you please tell me, how to copy a file from client PC to the sever in Web deployed application?
ThanksI downloaded D2KWUtil from the link suggested by you. It has very nice example demo form. But the documentation provided says following
Using D2KWUTIL in Web Deployed Applications
The use of this library is not supported with Web deployed applications.
In a web deployment scenario not all functions within D2KWUTIL will work. Any function that interacts with the User Interface (such as those in the WIN_API_DIALOG package) will fail.
Any interaction with the O/S by other functions will all be executed on the NT server and will act within, or return information pertinant to, the environment on that machine. For instance GET_COMPUTER_NAME will return the Server’s name, not the name of the computer that the Client browser is running on. Likewise COPY_FILE will copy files in the Forms Server not on the Client.
Functions such as those in WIN_API_BITOP will continue to work without change.
so this will not work in web deployed application.
Any other suggestion?
Thanks -

Client Program accessing J2EE entity Bean
I have trouble find my Course J2EE bean from a client. (The client
runs on the same computer but a different VM from the bean.)
In Glassfish (Sun Application Server Nine), I set up a simple
Container-Managed Entity Bean. I tried to access it from an external
client as described in the glassfish EJB
FAQ https://glassfish.dev.java.net/javaee5/ejb/EJB-FAQ.html
Here is the client program:

Debug.P(C.getName());

com.sun.corba.ee.impl.corba.CORBAObjectImplEarlier, I tried the version below, but based on the suggestion by Mr. Ebbert
in the forum started "Error When running the Client Program" by sree_devi,
I checked
the following. I went to "Jndi Tree Browsing" from the Administrative Console
and I found a "RS.CourseHome" entry under "ejb" I found RS.CourseHome there
but did not see the "Course" tghat I expected to see
Thus, I tried the version above:
package RS;

public class Client {
public static void main (String arg[]) throws IOException {
try {
InitialContext jndiContext = new InitialContext ();
Object o = jndiContext.lookup("Course");

Course C = home.create(1);
C.setName("blah");
CoursePK PK = new CoursePK();
PK.number=1;
C = home.findByPrimaryKey(PK);
Debug.P(C.getName());
catch (java.rmi.RemoteException re) {Debug.P("Remote Exception" + re.getMessage());}

catch (javax.ejb.CreateException ce){Debug.P("Create Exception"+ce.getMessage());}
catch (javax.ejb.FinderException fe){Debug.P("Finder Exception"+fe.getMessage());}
}When I run it, I get the following Naming Exception: Course not found
I confirmed at the administrative console, that I have "Course" listed
under Enterprise Applications:
As per the ejb FAQ, I set up my $CLASSPATH so it starts as follows:
/opt/j2ee/SUNWappserver/lib/appserv-rt.jar:
/opt/j2ee/SUNWappserver/lib/javaee.jar:I also verifed in my domain.xml that the orb-listener-1, the default
naming service port was at 3700.
Here is the info on the Bean that I have running for both of the tries

"some other processing" comprises of printing of debug lines and publishing to the message queue using JMS. I added more debug lines so that i could see whats really happening... here is the result
myTableHome.create(...); <----------- no exception was thrown and it returned LocalMyTable object
print out "Insert successful"
print out "publishing message"
... publish message to message queue using JMS...
print out "Publish done"
... after few milliseconds...
java.sql.BatchUpdateException: Data exception -- row already exist in index PK_MYTABLE on table MYTABLE.
From the exception it seems like its doing a batch insert. So that seems to explain why the java.sql.BatchUpdateException is thrown few milliseconds after my call to myTableHome.create(...);
Is it possible to disable batch update / insert? how?
thanks in advance,

New User M.Senthil..Hi,
Well,i don't know whether if this helps people here are not.
It is always a good practise to do it via Servlet and then download content.
The adavantage of doing this is
1). You may not need to pack the downloadable with the .war which you ultimately genrate which ceratinly help us in terms of faster deployment.
3). You may update the new content just by moving a file to the backup folder.
2).One may definately download the content irrespective to the content/file.
Hope example below helps..
Configurations:
In the above example we are assuming that we placing all downlodable file in D:/webapp/downlodables/ and you have configured the same path as a init param with the name "filePath" in your web.xml.
something like the one below.
<servlet>
<servlet-name>DownloadServlet</servlet-name>
<servlet-class>com.DownloadServlet</servlet-class>
<init-param>
<param-name>filePath</param-name>
<param-value>D:/webapp/downlodables/</param-name>
<!--Could use any backup folder Available on your Server-->

Urgent : problems in authenticating the client
Hi every one,
Im new to SSL and have a problem in authenticating the client with the server. when i disable
((SSLServerSocket)serversocket).setNeedClientAuth(true);
both the server and client work fine and i get the required output.
if i use -Djavax.net.ssl.truststore=trustStoreName and -Djavax.net.ssl.keyStore=keystoreName in the command line for the client then it works but i want to do it without the commandline options
I tried to debug the clients ssl handshake where it seams that if i dont mention the truststore and keystore in the command line it wont take the ones mentioned in the code.
If anyone has a solution for this or any idea can you please help me out im stuck on it for about a week now. Thanks in advance.

Deo_ZoneHi...
i'm new to ssl connection....i implement the code for ssl connection through java program...i use the following code
String keystore = "<java_home>/jre/lib/security/cacerts";
System.setProperty("javax.net.ssl.trustStore",keystore);
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.SECURITY_AUTHENTICATION,"simple");
env.put(Context.SECURITY_PRINCIPAL,adminName);
env.put(Context.SECURITY_CREDENTIALS,adminPassword);
env.put(Context.SECURITY_PROTOCOL,"ssl");
String ldapURL = "ldaps://mydc.speedrock.com:636";
env.put(Context.PROVIDER_URL,ldapURL);
DirContext ctx = new InitialLdapContext(env,null);
i use this code in my web application and using server tomcat 5.5 server...
Steps:
1. Started my tomcat server
2. attempt to change ActiveDirectory user password.
At this time i'm not importing AD server certificate into cacerts file..
In this situation it throws exception.
3. now i import the valid certificate into cacerts file using keytool command
keytool -import -alias xyzADCert -keystore <javahome>/jre/lib/security/cacerts -keypass changeit -storepass changeit -noprompt -file <java_home>/jre/lib/security/ca.cer;
when i run this command from console, import the certificate successfully....
4. now again attempts to change password...
In this situation it gives same previous exception....
But, when i restart the tomcat server and attempts change password, its working fine...
The same thing happens in case of delete certificate...
Steps:
1.Start the tomcat server

View data in client B from client A in the same SID without a valid logon?
Hi Folks
We are planning on upgrading our 4.6C system to ERP 6.0, and are initialy considering having two clients in the same sandbox SID. One would be for the developers to perform code remediation checks (client A), and one would contain a copy of production data for performing testing of functionality over live data (client B).
Would it be possible to view data in client B from client A in the same system without a valid logon to client B or RFC connection to client B from client A? For example via the use on an ABAP program to SQL the database?
I know one can use transactions like SM30/SM31 to view, compare, and adjust data between clients, but this requires an RFC connection and valid logon to the target client.
Regards
Kevin.Hi Kevin.

Short answer: yes.
If someone has the right to write and execute ABAP reports on the system he is able to access the data of all clients. So I don't think that this setup is advisable. Don't mix development and production data in one system.

V_Cpy_Result := Webutil_File.Copy_File ('C:\File_Name.Xml', '/u01/oradata/odsuat/ssr_xml_dir/Outbound/File_Name.Xml');
but this does't work, please provide me with the way or the command that I can copy the selected file from client to Unix DB server...Hello,
If you want to transfer files between client machine and A.S. or database machine, use the Webutil file_transfer package's functions.

How to find out a file from client machine
hi all,
I want to read a file from client machine, like a outlook express file in which all the address are saved, using servlet. Initially i do not know the file path for that file, How i can read that file.
plz help me
thanx in advace
ManishYou have 2 possibilities. First, you might be able to mount the client's disk drive at the server; the servlet can then access that drive directly. Second, install a client program on the client machine and communicate with that program, and have it do the search (or whatever).
Outside of Java, there are remote-access programs - like PCAnyWhere.
