Strange problem with NWDS - Custom code vanishes!

Hi all:
I am very much new to SAP NWDS world. I have got background in core Java coding and now trying to pick up the Java WebDynpro for which I am practising some examples in SAP NWDS.
I have got a Java WebDynpro application with 2 views. In the implementation tab of one view I am trying to put in some custom code for the function :
public void wdDoInit()
//@@begin wdDoInit()
//@@end
However after I hit the Save all metadata button, the custom code vanishes and the function wdDoInit() goes back to the initial form ( shown above ). As a result I cant save the custom code.
Any help with this issue?
Cheers!
Thanks
Anindya

Yes that's what I thought. But couldn't really find any forum on WebDynpro Java. So I put it in the NetWeaver Platform forum!
Thanks and regards,
Anindya

Strange problem with In-line If-Else block

Hi!
I've discovered a very strange problem with the following code:
enum Enum {
 A, B, C
 public static void main(String[] args) {
 Enum e = Enum.C;
 Object o = e == Enum.A ? 1 : e == Enum.B ? 2 : null; // Throws NullPointerException because of the null. Why???
 }I'm using Java 6
Thanks in advance!

Instead of guessing what the problem is, how about we go to [the source|http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.25] and see what's actually happening.
Our line is
expr ? <int> : (expr ? <int> : <null>)Let's look at the inner conditional first. By JLS 5.1.8, we have two different types, neither of which is a reference type. The null is convertible to int, so we have two types convertible to numerics and we apply unboxing to the null, which is where your error is coming from.
Your fix works because Object is not convertible to int, so we fall through to the last case and use boxing on the ints instead of unboxing on the null.
Another way to fix this is to use Integers instead of ints. Since Integer is a reference type, we hit the third case and never try to unbox.
Object o = (e == A ? Integer.valueOf(1) : (e == B ? Integer.valueOf(2) : null))

Strange Problem with Code Groups / Codes

Hey all, have a strange problem with Code Groups and Codes.
Our data migration team accidentally loaded an early version of our catalog (code groups and codes) in to our 'Gold' configuration client. They then proceed to delete them all via transaction qs41. However, the code groups have been deleted, but not the codes.
So, basically, no codes groups exist in table QPGR or QPGT but all the entries remain in QPCD with the assigment to code groups. The usage indicator is not set on the codes so why they did not get deleted with the codes groups is unknown.
The issue that this is now causing us is that we can't recreate the codes groups with these codes assigned as the system thinks they already exist (via a check on table QPCD i would expect).
Also, i have been unable to recreate what happened did in other clients... seems very strange.
Any help appreciated.
Cheers

Ben,
You could try SE11, and see if you can delete the records from there.. but I'm not hopeful...
Otherwise you may need to write a quick ABAP program to delete the data base entries.

Strange problem with Subviews on 1.0 Beta

Hi,
I'm having a strange problem with SubViews on 1.0 Beta. I'm not sure If I'm being stupid and have done something wrong, or if there's a problem here.
My application is directly based on one of the examples, so the structure etc is almost identical. I've simplified the files below to avoid confusing the issue.
The default landing page (greeting.jsp) looks like this:
<%@ taglib declarations for HTML and CORE taglibs %>
<HTML>
<HEAD><title>Insulation Layer Demo</title></HEAD>
<body bgcolor="white">
<f:view>
<jsp:include page="sysstatus.jsp" />

</f:view>
</body>
</HTML>
sysstatus.jsp looks like this:
<%@ taglib declarations for HTML and CORE taglibs %>
<f:subview id="SystemStatusView">
<h:form id="systemStatusForm">
<h:selectboolean_checkbox id="System1Available" value="#{SystemStatus.system1Available}"/>System 1 
<h:selectboolean_checkbox id="System2Available" value="#{SystemStatus.system2Available}"/>System 2
<h:command_button id="submit" action="success" value="submit" />
</h:form>
</f:subview>When I view this page, the checkboxes all seem to work okay (in that their state is preserved across calls etc), but the formatting is very screwy. The resulting page looks something like:
<chkbox1> <chkbox2> <Submit>
System 1
System 2
<Other HTML content from greeting.jsp>When I look at the HTML source code being generated, it is genuinly being generated as above, that is, all the form tags first, and then the rest of the content. Interestinly, I tried adding a ${SystemStatus.system2Available} into the body text, and it was rendered as literal text (i.e. not evaluated as EL), which is very curious -- makes me wonder if the included file is included as text, rather than JSP, although the custom taglibs and <f:form> tags etc are not in the generated HTML.
If I lift all the content between the <h:form> tags (inclusive) out of sysstatus.jsp and put it in greeting.jsp in place of the <jsp:include> tag, all is well.
Any ideas? All help gratefully recieved!
Thanks,
Paul

Personally, I think it is a bug in the rendering model of JSF itself because if you include any non-JSF tags, they don't get rendered according to my understanding of the what the spec says (in the location the tags are written).
The only workaround that I could come up with is to use straight JSF tags in all of your layers. Things are then rendered the way that they "should" be rendered.
You could try wrapping all of your HTML tags in <f:verbatim> tags and see if that helps.
Good luck!

Some strange problem with Flash/As3

Hi,
I am having some strange problem with my flash cs3.
Whatever script I write in as3 doesn't work, even a stop() function doesn't work . But when I change my publish setting to as2 it works fine.
Not sure about the root cause, may be some setting or preference or my cs3 is corrupted.
Can anybody please advise.
Thanks,

try this
create a new fla as3,

Hi Ivan
I have faced this problem earlier BUT ultimately I have to create the DC from scratch.
But you can check these things:
1.Have you copy/pasted Dictionary type from other location (check the path of the dictionary types ) --> If yes then deleted that and create again(do not use copy/paste)
2.This also happens if your "Used DC" has some problems in the JDI --> Remove the used DC and add it again.
3.Make sure the NWDI infastructure is perfect- this may be a cause.
4. Check Context mappings --> delete all mappings > save metadata > Create again.
5. Delete the model and recreate it again.
6.If you have done reimporting model make sure to restart J2EE instance.
Hope this solves the problem - if not please post
Regards
Ananda

Strange problem with connection to Integrator Server

Hi,
I have a strange problem with making a connection to my Integrator Server.
I have one workspace folder that I share between Integrator version 2.4 and 3.0 (I have several versions installed for testing purposes)
When I try to create a new Integrator Server Project in Integrator Designer I get this nice 'Connect to CloverETL Server' panel.
By default: the connection URL is http://localhost:8080/clover. So by default Integrator Designer wants to connect to my 2.4 Integrator Server.
When I change this to http://localhost:8301/clover by using the drop-down box and fill in my credentials everything is looking fine. I click Next.
The problem now is that every time I switch to the next or previous configuration windows the connection is reset to the default http://localhost:8080/clover.
So it seems like Integrator Designer resets the CloverETL Server URL each time I switch to a different configuration window by using NEXT or BACK.
The problem occurs in both versions of Integrator Designer.
Does anybody know that the problem is? Can I change the default URL to my 3.0 Integrator Server?
Greetings,
Marcow

I'm using iPlanet App server as well and experiencing similar problem. I load my SQL Server driver by Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"), then use DriverManager.getDriver() to obtain the Driver.
However, the Driver returned is not the SQLServerDriver as expected. The Driver returned is com.netscape.server.jdbc.Driver! And then when I do Driver.getConnection("jdbc:microsoft:sqlserver://MyServer"), it throws an SQLException saying that it doesn't accept a jdbc:microsoft:sqlserver subprotocol. Well, of course it doesn't, it's not a microsoft Driver at all.
I suspect the problem is that the netscape Driver's acceptsURL() method ALWAYS returns true in iPlanet app server, thus when you getDriver(), the netscape Driver is always returned (and always returned as the first one since it's default?). Thus even though the same piece of code works fine as a standalone application, it just doesn't work on iPlanet app server.
My work around is:
Class.forName("my.Driver");
Enumeration enu = DriverManager.getDrivers();
Driver useThis = null;
while (enu.hasMoreElements()) {
Driver d = (Driver)enu.nextElement();
if (d.getClass().toString().indexOf("my.Driver") > -1) {
useThis = d;
Mind that my above code does not have an performance issue. If you look into the source code of how DriverManager get a Driver for a particular URL, it also loads the whole set of available Drivers, then call acceptsURL() method on each of them to find the first "suitable" one. Thus time complexity is the same.
I know this is not a very elegant solution and it defeats the purpose of having a DriverManager. Does any one else has a better way to solve this problem, like a way to specify the priority of each Driver so that SQLServerDriver is returned before the netscape Driver?
Thanks a lot.

Strange Problem with Mail & Address Book

Hi,
I'm having a strange problem with Mail & Address Book.
When I go to compose a new message from Mail and hit the Address button (to show my email addresses), it won't launch the contacts window!
I get this log from console;
2007-10-15 22:55:59.079 Mail[410] * -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)
If I try to launch the Address Book from my Applications folder, it won't open, and it gives me this log from console;

I tried deleting the preferences, re-installing Address Book, also tried creating a new user, again no luck!
Can somebody help!!!
Please?!

Hi dp13.
Do you have any Address Book plug-ins or system utilities that could interfere with Address Book? In the Finder, go to each of the following folders (if they exist). What do you see there?
/Library/Address Book Plug-Ins/
~/Library/Address Book Plug-Ins/
To make accurately reporting this information easier, you may open /Applications/Utilities/Terminal, type the following command (you can just copy it here and paste it in Terminal), and press <Return>. You can then copy the output of that command from Terminal and paste it in your reply to this post:
ls -1 /Library/Address\ Book\ Plug-Ins ~/Library/Address\ Book\ Plug-Ins
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder. You can easily locate any of the folders referred to in this post by copying the folder path here, doing Go > Go to Folder in the Finder, and pasting the folder path there.
<hr>
Did you also reinstall the appropriate Combo Update after reinstalling Address Book?
Quit all the applications and verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all the filesystem issues, if any, reinstall the Combo Update for the type of computer and the version of Mac OS X you’re using, unless this is the version of Mac OS X that came with the computer:
About the Mac OS X 10.4.10 Combo Update
Mac OS X 10.4.10 Combo Update for PowerPC
Mac OS X 10.4.10 Combo Update for Intel
After installing the Combo Update, the computer may restart twice and the first restart may take several minutes. This is normal.
Take a look at the following articles for guidelines on how to properly install system updates:
Troubleshooting installation and software updates
Installing software updates
Basically, you should verify/repair the startup disk and back up before installing the update, no applications should be running while installing it, and you may experience unexpected results if you have third-party system software modifications (not normal applications) installed.

Strange problem with linking to external vob-file

I have a strange problem with linking to external vob-file. I
have created a link using BudApi:
on mouseup
set OK = baOpenFile ( the pathname &
"Files\General\Video\VTS_01_1.VOB", "normal")
end
This code opens mpg-videos correctly, but nothing happens
when I try to open vob-files with the same code. The strangest
thing is that when I change the default program for vob-files to
WinDVD this code works and the file opens, but when I change the
default program to Nero Showtime this code doesn't do anything
(when I open the file 'manually' from the folder, it opens
correctly on Nero Showtime). My client uses Nero Showtime, so I
really would appreciate any help on this one.

If you open a command prompt, do you get an association
listed like this
example for .txt files:
C:\>assoc .txt
.txt=txtfile
C:\>ftype txtfile
txtfile="D:\Program Files\JGsoft\EditPadLite\EditPadLite.exe"

Strange problem with Dreamweaver Pop-Up menus

Hello:
I have encountered a very strange problem with DreamWeaver
pop-up menus, and I was wondering if I could get some help from
this forum, as I can't seem to find an answer anywhere else.
The problem involves use of DreamWeaver's pop-up menu
behavior — all works as expected, and my local preview of the
Web page/site works fine, but when I upload the site to a server, I
see extra question mark and "box" characters added to my drop-down
menus. This problem is inconsistent between browsers: Sometimes I
see it only on IE, sometimes I also see it on Firefox.
For example, check out the following URLs:
http://libertycreativesolutions.net/clients/cci/
... this implementation of drop-down menus ("Services"
button, etc.) displays an extra "box" character for each of the
drop-down menu items, but this only occurs in IE -- Firefox is
fine.
http://libertycreativesolutions.net/clients/microtek/HTML/MicroTek_home.html
... this implementation of drop-down menus shows an extra
question mark above the triggering link onMouseOver for Firefox,
and in IE, it shows this "box" character for both the triggering
buttons and for each menu item.
For both of these sites, the pop-up menus work without a
problem *when I'm looking at a local version on my workstation*.
What in the Wide Wide World of Sports is going on here????
Any help for this problem is appreciated.
Note that I stripped out the JavaScript code for menu
information from the <head></head> area of each of
these pages and placed it in a linked JavaScript document.
HELP!

First, you need to read this, written by the person who
adapted that menu
code for Macromedia -
http://www.losingfight.com/blog/2006/08/11/the-sordid-tale-of-mm_menufw_menujs/
Then you need to know that there are MUCH better ways to do
such things -

Strange Problem with PAR deployment.

Hi Everybody,
I am undergoing with the strange problem with PAR deployment. When I am deploying any Par file its going successful but when again If I am changing this same PAR file in NWDS and deploying it ... its deploying but not showing the updated deployment version. To see the updated version, every time, I have to go Portal->System Admin->Support->Admin Console and DELETE the existing PAR file. But this procedure takes too time to work on each and every time. Can you help me with some new concept where the new deployed version will get updated on previous one without any manual process or if this something related to cache problem then how to work out?
Thanks,
Roshan Gupta

Hi,
If it saves you time you can also deploy from here:
.../irj/servlet/prt/portal/prtroot/com.sap.portal.runtime.system.console.ClusterAdminConsole
In some cases (rarely) I observed the behavior you described above.
In thoes cases after deploying the file I click the "clean" button on the bottom, since after the deployment it contains the name of the par you just uploaded it'll save you the time of looking for that par to earase.
After that you have to deploy the par again, but again it's allready in the browse console box.
Best Regards,
Nadav.

Strange Problem With Extra Spaces

Hello,
My development staff is experiencing a very strange problem with our JSP pages which display the values from a JDBC result set. We have two environments here: development and production. We have been creating pages in development which work out fine in our development environment. But when we move the page into production, each value which results from the ResultSet getString() method is having multiple blank spaces appended to the end of the value. So, for example, a 5 digit zip code field is really showing up with a length of 8 or 9 because there are extra spaces added to the end of the value.
We are able to work around this problem by using the trim() method, but this is getting quite tedious to do to every single page in the site. It is very annoying because the problem does not exist in the development environment.
So you figure there must be a difference in our development and production environments. But there really isn't. Here is the details for both environments:
OS: Windows NT 4.0
Web Server: Apache with Tomcat setup as a plugin
Database: Sybase ASA 6.0.3
JDK: 1.3
Apache and Tomcat were installed from the same download on both servers. Sybase was installed from the same CD on both servers - and the JDBC Driver (SybDriver) was copied from one server to the next.
Sorry for the long explanation - but does anyone have any idea what could be occurring? Why are the extra spaces being appended to the production pages and not the development pages?
As always, thanks in advance for any suggestions!

Hello Paul,
Thank you for taking the time to analyze this case.
The data in the system comes from two different sources. The first source is a nightly feed from a legacy system. The second source is user input via the JSP application. The records that were inserted from the nightly feed have an accurate length() value (meaning there is no untrimmed spaces trailing along.) But the values coming in from the application have extra spaces appended to them. In the development environment, however, both sources provide properly trimmed data.
If I enter an 8 character last name into the web form in the production app, the value which ends up in the database upon submission will have 2 to 3 extra spaces. I know that this sounds strange - and believe me, it is boggling everyone here. I suspect this problem has to do with the Tomcat installation - even though it was installed identically in each server.
I think we are just going to have live with using the trim() for every database submission. As always, thank you for the help, and all ideas are always welcome.

Strange problem with Domain Values

Dear All,
I encounter one strange problem with Domain Fixed Values.
Background:
We have a custom domain ( ZXREF2) created for custom data element(ZXREF2) which has replaced standard dataelement in BSEG for field XREF2. This domain has 12 Fixed values. The idea was to have F4 help for field "Reference Key2" in FBL5N/FBL01 tcodes. It is working fine with these 12 Fixed value, means, on F4 we could see all these 12 values and when selecting a line from F4 the entry got thru the screen validation ( plz note hat this validation is like checking the mandatory value so this is done even before PAI).
Problem:
The requirement was to add a new line to F4 values( tecnically, 13th record in domain ZXREF2). We added this line to domain and moved to Quality system. Its working fine in both Dev and Qality, but the strange problem occured after moving and testing in Production.
In production, we could see all 13 lines in F4 help. BUT, after selecting the new one( 13th one), and after the value appears on screen field, when Enter is pressed, it gives error message "Enter Valid value".
This error message also comes when we enter any value which is not there in F4. That means, system is able to recognize the new value in F4, but falied to validate that.
We thought that, this might be the problem with Buffer, and request Client to re-start the system. Even after system restart, it still gives the same error message.
Please note that, the error message is triggered even before PAI of the screen called. So noway( I already tried system debugging) we can debug this error message to findout the rootcause.
Any quick help would be highly appriciated.
Thanks and Regards,
Prasad.

Hello Max,
I guess DB Utility ( SE14 ) is to be run only when there is a change at structure level, to make Runtime and Database objects in sync. Here, we just added a new line to existing domain, and this added a new row to the Database table DD07T/DD07L.
Could you please expalin it more clearly if your view is different that what I just described.
Prasad.

Strange problem with jpcap library.

Hello everone;)
I have a very strange problem with jpcap. I have ubuntu 8.10, libpcap installed by apt (manually upgraded to 0,9,8) and jpcap 0.7 (installed from deb package).
My code is:
* To change this template, choose Tools | Templates
* and open the template in the editor.
package agh;
import java.util.logging.Level;
import java.util.logging.Logger;
import jpcap.*;
import jpcap.packet.Packet;
* @author iceman
public class Main
 * @param args the command line arguments
 public static void main(String[] args)
 try
 Tcpdump interfejsy = new Tcpdump();
 catch (Exception ex)
 Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
// agh_MainFrame ramka = new agh_MainFrame();
// ramka.setVisible(true);
 // TODO code application logic here
class Tcpdump implements PacketReceiver
 public void receivePacket(Packet packet)
 System.out.println(packet);
 public Tcpdump() throws Exception
 System.out.println("wszedlem do wykazu interfejsow");
 NetworkInterface[] devices = JpcapCaptor.getDeviceList();
 if (devices.length ==0)
 System.out.println("no devices");
 for (int i = 0; i < devices.length; i++)
 System.out.println(i + " :" + devices.name + "(" + devices[i].description + ")");
System.out.println(" data link:" + devices[i].datalink_name + "(" + devices[i].datalink_description + ")");
System.out.print(" MAC address:");
for (byte b : devices[i].mac_address)
System.out.print(Integer.toHexString(b & 0xff) + ":");
System.out.println();
for (NetworkInterfaceAddress a : devices[i].addresses)
System.out.println(" address:" + a.address + " " + a.subnet + " " + a.broadcast);
When i start this simple code it isn't working correctly. On the output i have only "no devices". JpcapCaptor doesn't see any mine network interfaces. On windows this code works correctly.
Anyone has any idea what is wrong?
Thanks,
iiceberg

Hi, guys,
I also have a similar problem but in Windows. I've been using a W2008 Server for a short time. For what I've seen and have been told, it works like a Vista. I've wrote a program which uses jpcap and winpcap and, first of all, gets the device list.
Well, if I boot my computer and log on with my usual account, which in theory is an administrator, gets 0 devices when I run the program.
Then, if I log on with the actual Administrator account i works perfectly.
And, if after logging and running the program with the Administrator account (NOT just logging on) I log on with my usual account, it works too.
It's like the Adm account has some kind of "top" permission that doesn't go away at logoff. I tried that because I had some other problems accessing the DVD-ROM for writing from my usual account.
I think that I doesn't happen in WXP, but I haven't tested that last problem, yet.
Any ideas??
Thank you.
