How to use URL iview parameters??

Thanks in advance,

Hi Ameya,
Basically, you need to create a HTTP system, then create a URL Iview giving this http system as a reference in it.
Check this <a href="https://www.sdn.sap.com/irj/sdn/thread?threadID=389042">thread</a> for details.
You can also refer to
<a href="http://help.sap.com/saphelp_nw70/helpdata/en/f5/eb51730e6a11d7b84900047582c9f7/frameset.htm">SAP Help Library</a>

but its now working .. so please help me how to slove this problem
If is not the correct way then please suggest me best way to achive this.
Thanks
Mukesh

Hi Mukesh,
I think this may work,
1, Create a HTML Layout.
    You can put your image wherever u want with HTML Codes.
    Check this, [Article|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3915a890-0201-0010-4981-ad7b18146f81] & [Help|http://help.sap.com/saphelp_nw04/helpdata/en/cc/00c93e9b2c3d67e10000000a114084/frameset.htm]
    With this, u can use the standard KM commands also.
2, U need to use KM Navigation iView for this rather than KM Doc iView.
3, In the Nav iView, u can use &rndLayoutSet=nameOfUrHTMLLayout to force the view with this new layout.

URL iView Problem - How to Use URL Parameter of Type 'User Information'

Hello URL iView experts
I am currently working on integration of backend-functionality with the help of an URL iView.
I want to use a parameter of type 'User Information'. In SAP Help Library it is said, that it is possible to set the value of a parameter according to a dynamic query on the users attributes. (Link SAP HELP)
It is also said, that one can retrieve the Logon ID of the users account.(Attribute Name: j_user -> Link SAP HELP Attributes )
I can choose the type 'User Information' but i don't know what to specify in the field 'Value'.
I have made a screenshot of the problem.->[Link to screenshot|http://img66.imageshack.us/img66/7782/urliviewproblemfrsdnthrel3.jpg]
But if i am calling the application this way, he doesn't retrieve the Logon-ID of the account, but he just uses the 'j_user' as value for the parameter.
Can you tell me, what i need to specify in the field value?
Best Regards
Marcus

Hi Marcus,
> It is also said, that one can retrieve the Logon ID of the users account
This is not correct; on the help.sap.com-page concerning the URL-iView-Parameters, it is printed that "other attributes (general, account, group, role) are not supported". The j_user attribute is part of the account group, so - not supported.
For your needs, it may be a better choose to use the AppIntegrator, which offers such a possibility by using "<User.LogonUid>"; see http://help.sap.com/saphelp_nw70/helpdata/EN/36/5e3842134bad04e10000000a1550b0/frameset.htm and https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/e0cbc309-ff89-2a10-8bad-bcde4c152ecb

How to use URL class instead of Socket

Hi all. I am developing a small inventory control system for a warehouse.
I am suing a Java desktop application that connects to a servlet via Internet.
I have been searching the net how to use JSSE for my application since i am new to secure sockets and JSSE.
Since I havent implemented security In my current system yet, i am using URLConnection conn = url.openConnection(); to connect to a servlet.
However, in a good tutorial that I found about JSSE, sockets are used directly for connection, insted of URLCOnnection. They use the code like this: SSLSocketFactory sf = sslContext.getSocketFactory();
SSLSocket socket = (SSLSocket)sf.createSocket( host, port ); Since, using sockets is overly complex for me, I want to make use of the URLConnection class instead to keep it simple.
Could anyone please tell me how to make use of the URLConnection class to establish secure http connection.
by the way, the tutorial is here:
http://www.panix.com/~mito/articles/articles/jsse/j-jsse-ltr.pdf
thanks.

Here you go. The following code snippet allows you post data to http URL. If you have to do the same to https URL , please let me know.
OutputStream writeOut = null;
HttpURLConnection appConnection = null;
URL appUrlOpen = null;
//data to be posted.
String data = "This is the test message to post";
byte[] bytesData = this.data.getBytes();
appUrlOpen = new URL(""Your Servlet URL");
appConnection = (HttpURLConnection) appUrlOpen.openConnection();
appConnection.setDoOutput(true);
appConnection.setDoInput(true);
appConnection.setUseCaches(false);
appConnection.setInstanceFollowRedirects(false);
appConnection.setRequestMethod("post");
appConnection.setRequestProperty("Content-Type","application/text");
appConnection.setRequestProperty("Content-length", String.valueOf(bytesData.length));
writeOut=appConnection.getOutputStream();
writeOut.write(bytesData);
writeOut.flush();
writeOut.close();
String inputLine;
StringBuffer sb = new StringBuffer();
reader = new BufferedReader(new InputStreamReader(appConnection.getInputStream()));
char chars[] = new char[1024];
int len = 0;
//Write chunks of characters to the StringBuffer
while ((len = reader.read(chars, 0, chars.length)) >= 0)
sb.append(chars, 0, len);
System.out.println("Response " + sb.toString());
reader.close();
sb=null;
chars = null;
responseBytes = null;

How to use URL CHIPs in Page Builder?

Hi all,
I have encountered a problem of using URL CHIPs in CHIP Catalog.
I cannot find any documents on how to use the CHIPs in CHIPs Catalog of Page Builder. I just simply want to display a URL in NWBC. I suppose that there is an input in URL CHIPs for URL addresses and then the URL can display. However, it is not the case.
I have already looked at the template of URL CHIPs (WDR_TEST_PAGE_CHIP_PROV_2) and still I don't understand how to use the URL CHIP.
Please give me some hints on this one.

How to open URL iView in new window

HI,
We are not able to open the URL iView, which is assigned to page, in new window.
We set the property "Launch in New Window" to Launch in Separate Window but no use.
Please let us know the solution
Thanks

Hi Tatayya,
Remove the delta-link that you have done for that iview to the page. Change the necessary settings on the iview level (skip this part if you have already done). Then re-"delta-link"the iview to the page and test if it open in a different window.
Could also be your cache, so go ..navigate via Sys adm--> Navigation -> clear cache.
Hope that helps.
