Hi All,

I need to know the use of this declaration. What does this code do.

`declare fieldEcho in "SAPXJutil.dll";`

`fieldEcho()` --- What does this function do?

Hello Arun,

generates you a list of html input tags (type=hidden) for each field in the last request sent; behavior can be seen in the (output of) login and changepassword templates.

hi

good

syntax: `declare fieldEcho, getLanguages

in "SAPXJutil.dll"; fieldEcho()`

and you can check if no language specified at the service level, you can provide the list of languages available in the system in drop-down by the following code:

`if (~language=="")`

<TR>

<TD>Language:</TD>

<TD><SELECT name=~language>

`if (getLanguages

("langId", "langDesc") == 0) repeat with i from 1 to

langId.dim` <OPTION selected

value=`langId`>`langDesc`</OPTION>

`end else`

<OPTION value=en>No allowed languages specified! Using

English as default.</OPTION> `end`</SELECT> </TD></TR>`end`

The following is an example login template for using the Windows NT domain controller for verifying the user's password:

`declare fieldEcho, fieldEchoWML, getLanguages in "SAPXJutil.dll";`

<h3>Please log on to the SAP System</h3>

<table>

<tr>

<td>

<form method="post" action="`wgateURL()`">

`fieldEcho()`

<table>

<tr><td>Service:</td><td>`~Service`</td></tr>

`if (~client=="")`

<tr><td>Client:</td><td><input name="~client" value="`RSYST MANDT`"></td></tr>

<tr><td>

<input name="~clientinput" type="hidden" value= "1">

</td></tr>

`end`

`if (~extauthtype == "DLL" || ~extauthtype == "NTpassword")`

`if (<sub>login=="")`<tr><td>Login:</td><td><input name="</sub>login" value="`RSYST-BNAME`"></td></tr>

<tr><td>

<input name="~logininput" type="hidden" value="1">

</td></tr>

`end`

`if (~password=="")`

<tr><td>Password:</td><td><input type=password name="~password" value=""></td></tr>

<tr><td>

<input name="~passwdinput" type="hidden" value="1">

</td></tr>

`end`

`if (~extauthtype=="NTpassword")

if (~ntdomain=="")`

<tr><td>NT domain:</td><td><input name="~ntdomain" value=""></td></tr>

`end`

`end`

`if (~language=="")`<tr><td>Language:</td>

<td>

<select name="~language">

`if (getLanguages ("langId", "langDesc") == 0)

repeat with i from 1 to langId.dim`

<option value="`langId<i>`">`langDesc<i>`</option>

`end

else`

<option value="en">No allowed languages specified! Using English as default.</option>

`end`

</select>

</td></tr>

`end`

`end`

<tr><td></td><td>`~MessageLine`</td></tr>

</table>

</td>

</tr>

<tr>

<td>

<table allign=center">

<tr>

<td>

<input type=submit name="~OkCode=/0" value="Logon">

</tr>

</table>

</td>

</tr>

</form>

</td>

</tr>

</table>

Hi Mrutyunjaya,

Thanks for the input.

Can you further explain some of the points.

<Form method = "post" action = "`wgateurl()`"

What is the service file does it call to login to SAP

<input type=submit name="~OkCode=/0" value="Logon">

What is the purpose of the okcode.

What program or service file does it call.
