How to get the host list in the wifi on mobile devices?

Hi
My AIR app need work on both Android and iOS.
ServerSocket and DatagramSocket are neither supported on mobile device. So how can I get the IP of other hosts in my wifi?
I tried to get the ip range and use socket to connect them one by one to check if they are available. But it's too slow. Is there another quick way?
Thanks

Thank you Saumitra Bhave. I download some samples and read some articles for how to use native functions.
But many things are sitll not clear to me, so I failed. Let me describe my flow:
1. compile all Java code to a .jar file, and put it into Android-ARM folder in my project.
2. create some functions to call the .jar with flash.external.ExtensionContext.
3. create a extension.xml to describe the path.
4. use command to compile .jar and AS functions into .ane with ADT.
then I can use this .ane file in any my AS project, right?
BTW, I'm using Flash Profassional, no Flash Builder 4.6.

How to get the Host name of Unix server

Hi all,
I am need to use the Host name of application server for some purpose.
where can i see the host name of the unix server ?

SYST-HOST or SY-HOST contain the name of the application server.
You may also use the following internal call to get the actual application server
call 'C_SAPGPARAM'
     id 'NAME' field 'rdisp/myname'
     id 'VALUE' field servername.
For the IP adress
CALL FUNCTION 'DB_DBRELINFO'
    IMPORTING
      dbinfo = dbinfo.
READ TABLE kernel_version INDEX 11.
kinfostruc-ip_address = kernel_version-data.

How can I get the host name from Email address?

hi
When I using socket to develope an email-sending servlet,I don't know how to get the host name from emial address.can you help me,thanks

Stripping off the user name will give you the domain of from field in the message. This is not the same as the host. Take a look at:
http://www.stopspam.org/email/headers/headers.html
Theres a pretty good discussion about email headers and how to use the information. You probably want to check the information here against the RFC.

How to get the current user name in Provider hosted app using appOnlyAccessToken

Hi,
Please help me, how to get the HostWeb UserName in Provider Hosted App
i have Provider hosted App, and Anonymous Authentication is enabled on AppWeb, using appOnlyAccessToken
Below code does not return current user who Log in in hostweb, it is returning
SharePoint App (app@sharepoint)
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
clientContext.Load(web.CurrentUser);
clientContext.ExecuteQuery();
clientContext.Web.CurrentUser.LoginName;
Below code gives a blank name when Anonymous Authentication is enabled, if Anonymous Authentication is disabled
app prompts for credentials
HttpContext.Current.User.Identity.Name
Thanks
Ram

Hi,
Since you are using a provider Hosted app if you want to get the current logged in name than do not use AppOnlyAccessToken else use AccessToken which is App + user Context AccessToken.
then
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
clientContext.Load(web.CurrentUser);
clientContext.ExecuteQuery();
clientContext.Web.CurrentUser.LoginName;will return proper user Name.
HttpContext.Current.User.Identity.Name will never return the user as this object is related to IIS server of your App Server not sharepoint.you should set this as Anonymous in case of provider hosted app.you can download the below sample which uses the AccessToken which has user name in it.https://code.msdn.microsoft.com/Working-provider-hosted-8fdf2d95

How to get the metadata in Designer?

How to get the UDDI Key to publish a service provider system in SR?

Hi,
I am following instruction in appendix 1 & 2 of the white paper at https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/1079b1af-dcb7-2b10-9ebb-eafcaa3cbbea?overridelayout=true
trying to publish a service provider system into the service registry. One thing not clear to me is how to get the uddikey as needed in step 6 in appendix 1.
My service registry is in a PI 7.1 SP4 system. I followed the instruction in appendix 2 but there is no uddi key displayed in the General tab. Please help.
Regards,
Jiannan
Paragraph extracted from the whitepaper:
There may be cases in which the NWA logical settings do not match the Services Repository
settings when Visual Composer is trying to locate the enterprise services. Such cases can occur
when there is no SLD ID definition of the physical system in the Services Repository.
Currently, Visual Composer cannot search for services on a physical system with an empty SLD ID
(which is not a valid one).
To obtain this capability, the following steps should be performed to generate the necessary data
for each system with a non-valid SLD ID, so that Visual Composer can search for services over it.
1.Log on to http://<serverName>:<serverPort>/WSNavigator.
2.Select the Services Registry radio button.
3.In the Find field, enter sr and choose Go.
4.Select the ServicesRegistrySi line and choose Next.
5.Under the Operation Name, search for the publishPhysicalSystems operation, select it and choose Next.
6.Fill the service information parameters with the following (see Appendix 2 for details on how to get this information) :
6.1.Click the + icon in the physical system[].
6.2.Deselect the Classifications checkbox.
6.3.Click the + icon in the classificationReferenceGroups[].
6.4.Click the + icon in the classificationReferences[].
6.5.Deselect the classificationSystemKey checkbox.
6.6.Deselect the uddiKey checkbox and enter the value <localUddiKey>.
6.7.Deselect the value checkbox and enter the value <localSystemHostName>.
6.8.Deselect the host checkbox and enter the value <localHostName>.
6.9.Deselect the physicalSystemKey checkbox.
6.10.Deselect the logical key checkbox and enter the value <System name>.<SystemHome>.<host name>.
6.11.Deselect the systemName checkbox and enter the value <system name>.
6.12.Deselect the type checkbox and enter the value 2.

Hi Jiannan,
No worries, you can go to UDDI client from the main page of PI i.e. http://<serverName>:<serverPort>/
And you use the search function for the TModel for your Physical System. Search parameters can use the % wildcard.
Hit the search and you find the UDDI Key for the Physical System.
Cheers.

When a file is uploaded, the file name is also submitted. The path of the file is available only to the machine within the Local Machine security zone. The value property returns only the file name to machines outside the Local Machine security zone. See About URL Security Zones for more information on security zones.
i need to know on how to get the compelete path /directory of the filename
using <input type="file"> tag You can't. Its a security thing.
is there any other way to get an input file from a local host aside from <input type="file"> tag?No. Not using just html.
You could always go into activex components, but thats different again.

How to get the IP address of smtp server?

For A record in DNS, we can use Java API InetAddress.getHostAddress() to get the IP address.
But for mx record, how to get the IPaddress?

If you know the hostname of the MX record (eg. mail.somehost.com), you can still use the InetAddress.getByName(hostname).getAddress()
If you don't know the specific host name you can do a DNS lookup directly:
        String host="somehost.com";
        DirContext ictx = new InitialDirContext();
        Attributes attrs = ictx.getAttributes("dns:/" + host, new String[]{"MX"});This will give you a javax.naming.directory.Attributes object from which you can...
Attribute att = attrs.get ("MX");This will give you all the MX records for the domain. To get the IP address of the MX hosts, you need to parse the record String returned. Usually something like:
somehost.com       MX preference = 10, mail exchanger = mail.somehost.comParse out the mail.somehost.com and use:
    String mailhost = <Parse MX record here>
    InetAddress host = InetAddress.getByName(mailhost);

How to get the iphone serial number in application?

hello, everyone
i really want to konw how to get the iphone serial number in aplication ? As it's different from uniqueIdentifier ....
thank you

Michele is correct - sneep will help you get the serial from the running domain on the M3000 ,
and it is a good idea to install STB on your machines.
If that isn't possible for you, then sneep can be downloaded directly from [http://www.sun.com/sneep]
I believe that on this platform, sneep gets the serial from the output of prtconf.
There is a minor correction to be made :
After installed SNEEP use "man sneep" for all technical details.The sneep man page is not linked into the shared man pages, so you need to use
man -M /opt/SUNWsneep/man sneep
with out going to OK prompt (Banner)It is worth noting that the serial shown in the OBP banner is not the product serial
that you will find on the physical serial tag.
The banner "serial" is the decimal equivalent of the host ID, which you normally get in hexadecimal from the "hostid" command.

How to get the remote user IP address if behind the proxy or firewall

Hi
How do i get the remote user Ip address who is invoking the servlet behind from a firewall.
When i use getRemoteHostAddr it gives the proxy ip address not the actuall user host address... Kindly let me know how to get the actual user ip address
satish

There is no reliable way to determine the original IP, and such information is not useful to you if the original IP is behind a firewall. What do you propose to use it for? There is probably an alternative way to do things that does not require the remote IP.
