Reading POST-Request-Parameter-Values from WebDynPro now possible?

Hello,
in the past I always was disappointed that in WebDynPro there was no way to read POST-request-parameter-values directly after the call of a WebDynPro-Application.
The only (documented) way to read / transfer request-data into an WebDynPro-application was via "URL query string parameters" in the request URL.
The last week I forgot this restriction. I called my WebDynPro-application using a POST-Request-Parameter (cookie_guid) instead of an URL-parameter.
After noticing my mistake, I was really surprised that the WebDynPro could read / shows the the POST-Request-Value.
I didn't make any changes in the coding of my WebDynPro-Application (zvis_show_sso_cookie).
After this cognition I built the following simple HTML-formular to analyse the behavior of the WebyDynPro by calling it with an URL-Parameter (cookie_guid=Url-GUID) together with the POST-Parameter (cookie_guid = Post-Value-GUID).
After calling the WebyDynPro it reads / shows the "POST-Value" of the request !!!
(Remark: If I made a simple refresh or type directly the URL "http://hg10762.vis-extranet.de:1080/sap/bc/webdynpro/sap/zvis_show_sso_cookie?sap-language=DE&cookie_guid=Url-GUID" in the browser, the same webdynpro reads / shows the URL-Parameter-Value).

        <input type="reset" value=" Abbrechen">
      </td>
    </tr>
</table>
</form>
</body>
</html>
My questions:
I there any documentation that describes the behavior of WebDynPro after calling it by using POST-Parameter values?
I believe in the past it wasn't possible to read POST-request-parameter-values in WD. Has SAP changed the functionality?
Is the behavior I described in my example above mandatory?
Regards
Steffen

As far as i know in general HTTP request GET method is standard but in SAP POST is standard. All the client request is passed as POST to the server in order to avoid the URL parameter length restriction in GET method.

Unable to get parameter values from a remote database

I am linking to a remote database view via a synonym in Oracle and trying to retrieve parameter values from it. The username and password are the same for the local and remote database and I can run the SQL query using SQL plus against the database and values are returned. However, when I try and run the same query in Crystal Reports (XI) I receive an Oracle error:
"An attempt was made to connect or log in to a remote database using a connection description that could not be found.
Action:
Specify an existing database link. Query the data dictionary to see all existing database links. See your operating system-specific Net8 documentation for valid connection descriptors. "
How can it be that Crystal cannot run the query when it is valid in SQL plus?
Any tips/info would be appreciated.
many thanks
Claire
Oracle is version 10

When running one of the reports in VS.Net this is the error I receive:
"A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in crystaldecisions.crystalreports.engine.dll

When running the same report in Crystal Reports designer I receive this error message:
"Prompting failed with the following error message: 'List of Values failure: fail to get values. [Cause of error: Failed to retrieve data from the database. Details: [Database Vendor Code: 2019].

So this one is also failing in the designer.
All the parameters in the main report are static and the ones in the subreport are passed in from the main report.

How to omit parameter values from exceptions thrown by the JDBC driver

Is there a way to get the Oracle JDBC driver to omit the parameter values from the message when it throws an exception?
We have an application that persists credit cards and when an exception is thrown by the driver, it's including the credit card number in the error message, which ultimately gets logged by the application. There are too many layers and locations, including OpenJPA, Spring, and our own application, where we'd have to massage the error data to remove that card number.
For example, we get the following exception:
Caused by: org.apache.renamed.openjpa.lib.jdbc.ReportingSQLException: ORA-20104: Permission denied
ORA-06512: at "PROTEGRITY.PTY", line 57
ORA-06512: at "PROTEGRITY.PTY", line 383

at org.apache.renamed.openjpa.lib.jdbc.LoggingConnectionDecorator.access$800(LoggingConnectionDecorator.java:57)
The actual content of the message appears to come from the JDBC driver, not OpenJPA.
This particular example doesn't show the card number, but only exposed that possibility as a risk.
BTW: before you ask, for PCI compliance we're using a database layer service to encrypt the card numbers before they're stored in the table.
Thanks much.

Get parameter value from PLSQL portal Item

Hi,
i have some page link like :
http://server:7777/portal/page?...&myparameter=test
I don't know how to get myparameter. I want to access this parameter value in a PlSql portal Item in this page
can somenone help me ?
is there an API to get those parameters?
thanks in advance
Joao

If do you want to get a parameter value from an item, you'll need to construct a procedure that receive your parameter value and configure your item to call this procedure.
But If you want to get a parameter from a portal page, first you need to configure the parameter in page properties, construct a portlet and configure "function describe_parameters" to get the parameter and work your parameter in "procedure show".

Problem in getting parameter value from selection screen in web dynpro abap

    ENDCASE.
ENDLOOP.
So, can any one solve this problem.
Thanks in advance,

Hi Radhika,
Try using GET_RANGE_TABLE_OF_SEL_FIELD...
Please Refer below code..
   DATA: NODE_FLIGHTS TYPE REF TO IF_WD_CONTEXT_NODE.
DATA: RT_CARRID TYPE REF TO DATA.
DATA: ISFLIGHT TYPE TABLE OF SFLIGHT.
DATA: WSFLIGHT TYPE SFLIGHT.
FIELD-SYMBOLS: <FS_CARRID> TYPE TABLE.
Retrieve the data from the select option
RT_CARRID = WD_THIS->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD( I_ID = 'S_CARR_ID' ).
Assign it to a field symbol
ASSIGN RT_CARRID->* TO <FS_CARRID>.
CLEAR ISFLIGHT. REFRESH ISFLIGHT.
SELECT * INTO CORRESPONDING FIELDS OF TABLE ISFLIGHT FROM SFLIGHT
                       WHERE CARRID IN <FS_CARRID>.
NODE_FLIGHTS = WD_CONTEXT->GET_CHILD_NODE( NAME = `FLIGHTS` ).
NODE_FLIGHTS->BIND_ELEMENTS( ISFLIGHT ).

The customer want to use particular F4 help on report, but some input value before press enter key are not used in event of "at selection-screen on value-request for xxx", How to get parameter value in this event?

You probably want to look at function module DYNP_VALUES_READ to allow you to read the values of the other screen fields during the F4 event... below is a simple demo of this - when you press F4 the value from the p_field is read and returned in the p_desc field.

Now i am in new SRM 5.0 project where we are using integrated ITS and i developed small screen in which I am trying to read the value which I am entering in template text filed.
In debug mode i could see that ,when it execute FIELD-GET macro getting SY-SUBRC is equal to 1. I am not able to get the template value in PAI because of macro failure.
I just copied the same program which i developed in external ITS system still same problem.
Please some one help me if I am missing some thing in this.
Code which i am using.is

<textarea name="FREE_TEXT_DES" cols="35" rows="10" onKeyPress=fmlength()> </textarea>
<input type=submit name="~OKCode=TEXT" value="Send text">
</form>
In Back end code of PAI.
move sy-ucomm to ok_code.
data: len type i.
   data: idx type i.
data: wide_row(80) occurs 0 with header line.
   data: wide_text(80) occurs 0 with header line.
   idx = 1.

Read Query String Parameter Value in SSRS

Hi,
We have Project Server 2010 and Sharepoint Server 2010 env and using SSRS 2008 R2 for reporting purpose in Native mode.
Here I am displaying the SSRS Project report in Project Server page using Report Viewer web part like below.
Here I want to read projuid query string parameter value (Highlighthed above in URL ) in SSRS by using any way, so that I can pass that
projuid value in my SSRS report parameter to filter and make this report dynamic.
Right now I have to select the ProjectName (Label) which passes ProjUID
as value from the Parameter, but I want it should read the projuid
from URL so that this reports will display the project the data for the opened Project automatically
Thanks and let me know in case we can achive this using OOTB or some custom functions.

Hi,
For the report parameter, you can get the value from database query or some embedded funcitons etc. or even some customerized function.
You may consider to create your own code for the report to read the projuid from application or URL. The customer code can be used to get the values from the applicaiton or from the url etc. Then report can call the customer code function to get the value.

Very Urgent please help me. --Request parameter value returning null

Hi
I am getting null values for the request parameter. The following is the code snippet.
The following code working well when I rolled back to my old version. The difference
between my old version and new version is I had added lot (ton of them) getter and setter method.
Initially not much code left int the class. The value is passed from the jsp (when clicked). Once again the same code is working when I rolled back to old version.
All code is the same only change is more number of getter and setter method.
Please help me.
Thanks in advance

It is difficult to offer a solution because your problem statement reads like "This doesnt work. Help Help. Oh it doesnt work. Help. It works only for two days. Please Help."
Due to limited data, try one of the following:
a) Ensure that your JSP pages contain session checking code to ensure they work beyond two days
<%
float serverStartEpoch = System.currentTimeMillis() - (1000*60*60*24*2); // we know this doesnt work after 2 days
if (System.currentTimeMillis() > serverStartEpoch) {   // beyond failed time
    System.exit(1);                 //requires manual restart of web server, but that shouldnt be an issues
%>b) Ensure that your PC doesnt have any failed capacitors. Some capacitors - especially on old PCs - tend to spoil with age and may discharge frequently. Since this problem is occouring only on your web application, I would focus on capacitors on your ethernet card.
Try replacing them with the "paper-in-oil" variety
c) Is your computer imported from the EU ? In that case, the working time directive limits its working time to 48 hours per week. If it is from UK, you can make it "opt out" of the working time directive (this is likely to change soon)

How can i pass parameter values from html to a shell script

Hi Guys...
I had a requirement where i need to execute a sql statement and print the output in HTML page. This report has parameters to enter. So i created a HTML form which accepts parameters. When the submit button is pressed, the action tag in the form invokes unix shell script file. It will open sqlplus and run the sql script file .sql and print the output in the HTML page.
sql script contains the query and some set options which prints the output in HTML page. Like "SET MARKUP HTML ON"... The query has some parameters like "select * from emp where empno = &&empnumber. I will use the same name "empnumber" while created the HTML parameter form like " <input type = "text" name="empnumber" size="10" align="left">.
user sees this parameter form and enters some value in to that empno text box.
My question is how can i catch these parameter values in a shell script and pass it to the sql script to execute it.
Help Appreciated
Thanx

This is a A Bad Idea (tm). This type of CGI processing is old and were (and still is) full of security holes. Very easy to inject stuff (Unix commands and SQL) into it.. To get those parameters into SQL*Plus requires using Unix shell commands to process it - and something like a backquote allows all kinds of nasty stuff to be injected. The Unix shell was never designed to be used as a secure CGI environment.
There are far better and far superior alternatives. Perl (with Perl_DBI) and PHP (using Zend Core for Oracle) come to mind as web scripting languages.
Even easier is using HTMLDB. Very few moving parts. Is free. Supports Oracle 9.2 and 10G.

Parameter value from app is not being used

Hi,
I have .NET application which renders the report from BOE using infoObject model. This report has parameter and the paramter info is passed from the application using following code.
CrystalReportViewer1.EnterpriseLogon = enterpriseSession;
CrystalReportViewer1.ReportSource = (Report)infoObject;
CrystalReportViewer1.ParameterFieldInfo = parameterFields;
But when I try to run this form...though the parameterfields have the detail of the paramter still Promt screen is scheduled by BOE to provide input for the parameter...
Can someone help me on this why the parameter value I am sending is not being used.
Thanks

It might have something to do with how you are creating your parameter field collection that you are passing to the viewer. Please refer to the ViewReportParameter sample in the following collection available [here|https://boc.sdn.sap.com/node/5794]

Passing parameter value from one script to another in job chain steps

Hi all,
We have a scenario where in we have a job chain with two steps
1-Step 1 contains a script which fetches value from database to the script parameter(in/out) - PAR_DB_VALUE
2-Step 2 contains another script which uses the value of the parameter PAR_DB_VALUE and has to assign to another parameter in the script 2 called PAR_FETCHED_VALUE(in)
How to pass the value of PAR_DB_VALUE to PAR_FETCHED_VALUE which are parameters in two different steps
Please help
Thanks and Regards
Raj

Hi,
You can achieve this as follows (CPS version 6 & 7):
- Edit the chain
- Go to the second step, to the parameters of the script call in that step
- Go to the parameter (PAR_FETCHED_VALUE) that you want to be filled by the parameter of the first step
- choose "Chain value" in the detail screen for the parameter, and select the desired out parameter from the drop down
Note that both parameters need to be of the same type for this to work.
Regards,
Anton.
