Get server and client ip address and port

[Former Member]

Hi!! I want to get the address and port of the server where the application is running and the same information of the user who is connecting.

Since I'm using NW04s I can no longer use the hijack:

HttpServletRequest req = ((IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest();

String baseURL = "http://"req.getServerName()":"req.getServerPort()"/VideosTutorialesGAT/index.jsp";

I'm succesfully using the WDProtocolAdapter to get the address, like this:

String dirIP = WDProtocolAdapter.getProtocolAdapter().getRequestObject().getClientHostAddress();

But I can not find the right command to get the port number... where can I find this information??

Thanks a lot!!

I was happy since it worked, but then I remembered that I read in the blog below that we ought to use only the clases which names begin with WD or IWD only... is there another way to get the port??

Hi Alejandro Monteverde,

See this thread:

Also, you can read the http header for getting server & port.

BTW, if you need the url for navigating to a portal component/application/document you don't need the server & port, you can use relative path.

For example if you are running WD application called 'A', you can open WD called 'B' you can write:

IWDWindow window = wdComponentAPI.getWindowManager().createExternalWindow("/webdynpro/dispatcher/local/Bprj/Bapp", "", false);
window.open();

In your case use:

IWDWindow window = wdComponentAPI.getWindowManager().createExternalWindow("/VideosTutorialesGAT/index.jsp", "", false);
window.open();

Same for KM document or JSP file...

Omri,

Your hint leads me to the following:

1. java.net.InetAddress.getLocalHost() returns InetAddress of local host, inetAddress.getCanonicalHostName() returns the fully qualified domain name for this IP address. Now we have FQDN of server:

final java.net.InetAddress myAddress = java.net.InetAddress.getLocalHost();
final String httpHostName = myAddress.getCanonicalHostName();

2. If you know, WebAS Java sets ceratin JVM properties when starting JVM, these properties are available via System.getProperty(). So we can get following variable:

final String instanceNumber = System.getProperty("SAPSYSTEM").toString();

4. Http port in WebAS Java is composed as 50000 + instanceNumber * 10 (50##0 where ## is instance nuimber), hence

final int httpPortNumber = 50000 + 10 * Integer.parseInt( instanceNumber );

Puzzle solved! No non-API calls! Neither WD API calls

That last one is the answer I was looking for!!! the only issue there is that you should multiply by 100 instead of multiplying by 10.

Thanks a lot!!!

hi ,

check out following code

String hostName = TaskBinder.getCurrentTask().getProtocolAdapter().getServerName();

int port = TaskBinder.getCurrentTask().getProtocolAdapter().getServerPort();

hope it helps
