Front End (GUI) for Java Web Based Appl.

Hi Gurus,
I am new to Java. Can anybody tell me, what is the front end(GUI) used in Java web based applications? I was told that Swings/Applets are rarely used. Is there are a 3rd party took to design GUI for Java based applications?

we cannot have swing as front end?You can use Swing inside an Applet inside a web application, but usually that's not needed, as you already have a client application that's quite powerful (the browser).

Unable to Print Purchase order automatically using SAP GUI for JAVA

Hi SAP gurus,
Some of the PC's in our company use windows and some LINUX. Therefore we use two types of SAP GUI. One for windows and the other one JAVA. PO approval was set to print automatically. In a windows setting, there are no problems with this setup. But in SAP GUI for JAVA, no print outs are produced and no error messages are displayed. I am using SAP GUI for JAVA version 7.10 ver 6. and I use Front end printing for linux access method G.
please help,
gungertz

hi gungertz,
You can use U type access method for printing SAP document using linux desktop.
Please refer to my blog posting here (http://sapbasis.wordpress.com/2007/08/23/print-sap-documents-using-linux/)

Help needed in creating Front End GUI

Hello all,
Iam trying to develope a Front end Gui. Reading data from a spread sheet, which has the following data 6 cloumn's 1) Parameter 2) Group 3) Max value 4) Min value 5) Default value 6) Value. Group is pretty much again classified in to 4-types.
a) Temperature group --- Slide
b) Switch --- Push button
c) Sensor group (voltage or pressure) ---- Knobs
d) Digital Inputs --- Numeric Input
From the spread sheet,for each parameter based on what type of group I should to create either a slider, or a switch or a knob or a Digital Input. And Based on 3rd and 4th column information, scale should be adjusted. 5th column should be used to set a default value and 6th column to assign a value
to that parameter.
Some one pls give me any suggestion how to approach, begin with this process. Iam worried how to classify the parameters in to group's.
-Lucky.

You could set up 15 to 20 controls of each type on your front panel. You will need to work with references to each control to get and set properties since there will be no way to wire them up to any specific functions on your block diagram since which controls mean what will vary during run time. So you would move the block diagram terminals for the 15-20 controls of each type off to the side of your diagram.
When you go through your setup spreadsheet, you can set the visibility and front panel coordinates of each control you want to use. For any you don't want to use, you will make them invisible. Use property nodes to set the properties of each control.
When you want to read from or write to a control, you will need use the reference of the particular control with a property node to get or set its value.
This is not an easy archtitecture. You will need to maintain arrays of references for each type of control. You will also need to maintain a cross reference array so that you if want to access Control C (for example), you know which reference to index out which might happen to be element 1 in the array of slide references. Perhaps control G would be element 4 of your array of knob references.
But with good organization of your control references and perhaps some good subVI's for setting and obtaining the references so you can index them out of the appropriate array, it can be done. I would recommend looking at Ben's Action Engine Nugget for ideas of how to store the references in a functional global variable.

How to set a default start and/or end date for New Events based on trigger date.

I'm using the CalendarActivityListener to get current row when clicking on an existing event. As per previous posts this listener gives you access to event detail including Start Date, End Date, etc.
However, what I want to do is to default the start (and end) dates for New Events based on the trigger date.
I've tried the CalendarListener and can grab the Trigger Date from it - however, I can't see a way to pass this directly to the popup/dialog I'm using to create the new event.
At present I'm putting the TriggerDate into the ADFContext session scope e.g. ADFContext.getCurrent().getSessionScope().put("TriggerDate",calendarEvent.getTriggerDate());
Then, I've tried multiple approaches to try and "get" the TriggerDate from session scope to drop it into my new Calendar Event basically, I'm trying to default the InputField(s) associated with the Start Date using the value from the session - I've tried
1. setting the default value for the InputField in the jspx using a binding expression i.e. value="#{sessionScope.TriggerDate}" - this actually sets the value appropriately when the jspx is rendered but, when I go to create I get a NPE and I can't debug. I assumed that it might be a Date type issue - it would appear that CalendarListener provides a date of type java.util.Date and that the StartDate attribute of my VO/EO/table is a DATE and therefore requires oracle.jbo.domain.Date so I tried casting it - to no effect
2. Using a Groovy expression *(StartDate==null?adf.context.sessionScope.TriggerDate:StartDate)* in my calendar's EventVO to default the Start Date to the same result
Any thoughts or ideas?

John,
Thanks for that suggestion - could not get it to work. However, I did manage a different approach. I finally determined the sequence of events in terms of how the various events and listeners fire (I think).
Basically, the CalendarActivityListener fires, followed by the listener associated with the Calendar object's Create facet, followed finally by the CalendarEventListener - the final is where the TriggerEvent is available and then finally, control is passed to the popup/dialog in the Create facet. So, my approach of trying to set/get the TriggerDate in the user's HTTP session was doomed to failure because it was being get before it had been set :(
Anyway, I ended up adding a bit of code to the CalendarEvent listener - it grabs the current BindingContext, navigates through the DCBindingContainer to derive an Iterator for the ViewObject which drives the calendar and then grabs the currently active row. I then do a few tests to make sure we're working with a "new" row because I don't want to alter start & end dates associated with an existing calendar entry and then I define the Start and End dates to be the Trigger Date.
Works just fine. Snippet from the listener follows
BindingContext bindingContext = BindingContext.getCurrent();+
*if ( bindingContext != null ) {*+
DCBindingContainer dcBindings = (DCBindingContainer) bindingContext.getCurrentBindingsEntry();+
DCIteratorBinding iterator = dcBindings.findIteratorBinding("EventsView1Iterator");+
Row currentRow = iterator.getCurrentRow();+
if ( currentRow.getAttribute("StartDate") == null)+
currentRow.setAttribute("StartDate", calendarEvent.getTriggerDate());+
if (currentRow.getAttribute("EndDate")==null)+
currentRow.setAttribute("EndDate", calendarEvent.getTriggerDate());+
*}*

SAP GUI for Java 7.10 rev 7 - strange behavior using mouse

Hi,
I use last revision of SAP GUI for Java 7.10 on linux and I've noticied that some mouse actions do not work as expected. I'll use describe an examples:
(1)
In rev.6 I simly push button on screen and move over text, text is marked and then I can use CTRL-C to copy text to clipboard.
In rev.7 pushing button and move does nothing. I need one initial click more and then it works as expected.
(2)
Click to icon in an ABAP list sometimes activate another icon from screen (it seems that focus isn't moved from its previous position to new mouse cursor position).
Because rev.7 has been released at the end of 2008, it is possible, that some dotted revision (solving these troubles) has been released, does anybody know solution?
Thank you for some hints,
Pavel

Hello Pavel,
we have not yet been aware of such issues, so a newer dotted version would likely not make a difference.
(1) The behavior pretty much depends on the specific component you are clicking and selecting its text.
So a specific test case identifying the component is required to investigate the issue.
(2) Also for this case I ask to provide the exact context, even if it happens there only "sometimes".
Please provide also information requested in [note 326558|https://service.sap.com/sap/support/notes/326558], parts 2.) and 3.)
If you could provide all this as part of a [support message|http://service.sap.com/message] would be great.

Dear Rolf-Martin,
I have problem w/ sapgui java that puzzled me all along ...
I've downloaded SAPGUI Java 700r2.1 .. then successfully installed in my PPC ibook G4 ... up and running well ...
one day my colleague with a new MacBook (Intel Core Duo 2GHz) want to have SAPGUI ...
i installed it, run the apps, it works well to the point of SAPLOGON window ...
But it cannot connect to any server defined ...
When I create a new connection, it correctly connected to server and group list can be chosen, but still when I click it to connect nothing happened as if the program not running.
Java -version is 1.5.0_07 .. software update checked, no issue with Java or else ...
I've also try to change the JDK to 1.4.2 to no avail.
I'm stuck. system already re-installed. install sapgui from fresh but problem still persist.
No clue from Googling ... no clue from sapnotes ...
Would you please point me to something so I can dig in ?

Which file on the DVD should I select to install front end gui

Hello Basis gurus
I am trying to install the Front End Gui on my laptop (SAP GUI for Windows 7.20).
The older versions had a file called SETUP.EXE which I used to select to install the Front End Gui.
However, on this CD I don't see that file.
I read the Installation Guide which gives 2 scenarios.
1. Creating an installation server and then use that to install on different systems on the network.
2. Taking the CD to each windows client and install it directly from the CD.
However, the installation guide explains the scenario 1, installing using installation server.
There is no explanation of how to do the installations directly from CD. Since I don't see the setup.exe file, I don't know what else to do. Has anyone done this? If so could you please let me know. I would appreciate it.
Thanks a lot
R

If you are talking about the NW 7.0 Presentation DVD/CD for the SAP GUI 7.20 installer, once extracted, I believe the setup you are looking for is located here:
Under NW_7.0_Presentation\PRES1\GUI\WINDOWS\WIN32
From that location you should see the setup executeables.
SapBiSetup.exe
SapGuiSetup.exe
SetupAll.exe
If you run the SapGuiSetup.exe, that should install 7.20 for you.
If you run the SetupAll.exe, that will present you with options you want to have installed along witht he SAP GUI. (Business Explorer, Engineering Client Viewer, etc.Planning Grid, KW Add-On, etc)

Looking for a web based filemanager (or similar).

Hello,
I have a small server at home hosting all my files and I am looking for a simple setup to be able to access these files from pretty much every where.
Usually I'm using ssh or sftp but the thought of being able to access the files through a web interface is really sounding good. So, I have been searching for a web based file manager and found a few, but none that really made me go wow.
The best so far is probably Ajaxplorer. One thing that I'm looking for though is a PAM authentication feature which Ajaxplorer doesn't have. Are there any web based file managers around that supports this?
Or... maybe I'm looking for the wrong things. Are there other nifty solutions available for accessing files on a remote folder through a web interface?

zenlord wrote:
If PAM authentication is all you're missing, why don't you setup http_auth?
THX for the suggestion, I was looking for something like this myself and the next version should have LDAP_auth - alrighty then!
Zl.
http_auth... do you have any nice links on how to use it? I've never heard of it
Ajaxplorer is quite nice after all and setting up repositories isn't all that bad. Looks like I'm sticking to it while I continue my search for another app.

SAP GUI for Java 7.00 rev 4 - bug in ABAP download

When I try to download ABAP source code or when I use "Edit Locally" in SE38 (the easiest way how to write/edit programs with a comfortable editor), ABAP source is downloaded to my computer with trailing 0x00 bytes. It has small side-effect in Local Editing: new code with this block is uploaded into SAP and syntax check of such program fails.
Using 7.00 rev 3 works fine.
Has anybody idea how to eliminate this bug?

SAP GUI for JAVA - Search Help ALV display

I need to be able to display search helps in the ALV grid format or the ' Dialog Modal ' option as seen on the Settings for all F4 helps tab under the personalize option for search helps.
Currently when I am using a Macintosh machine the system ignores the system setting and my personal settings and displays all search results in an ABAP List format. Unfortunately the ABAP list format does not work correctly when used to input a field on another ABAP list report.
This behaviour can be found on the Mozilla Firefox browser when SAP GUI for HTML and the SAP GUI for JAVA.
Your help will be greatly appreciated.

Hi Rolf-Martin,
Thank you for your detailed explanation on how the ALV grid control is implemented for the SAP GUI for Java. This has been pretty insightful. The good news is that I finally figured out a solution to my problem. You see I inherited an old custom program where an ABAP list is used as an interactive data capture screen with input fields. Well a couple of fields had search helps. The program has worked fine with the regular SAP GUI until a MAC OS user tried to use it with the SAP GUI for Java. Whenever they selected a line from the search help it would bring back the entire onto their input screen.
A sample of the code:
form search_help.
 CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
 EXPORTING
 TABNAME = 'EKPO'
 FIELDNAME = 'MATNR'
 SEARCHHELP = 'ZMAT1_A'
 SHLPPARAM = 'MATNR'
 TABLES
 RETURN_TAB = RET_TABLE.
IF NOT RET_TABLE-FIELDVAL IS INITIAL.
 LINXX-XMATNR = RET_TABLE-FIELDVAL.
 MODIFY CURRENT LINE FIELD VALUE XMATNR FROM LINXX-XMATNR. " ****
ENDIF.
SET CURSOR 9 SY-CUROW. " ********
endform.
The problem was being caused by the fact that the search help ABAP list was overriding the sy-XXXX values for the current line contents, index, pageno, cursor row for the calling ABAP list. So when a user selected a row from the search help this would now become the current context and be transferred back to the calling program.
The fix was pretty simple; all I had to do was save the current line context and the context prior to calling the search help. After the search help was run I would then replace the current line with the saved one in my local variable. I hope this makes sense. We now have a couple of happy MAC OS users.
Once again I thank you for your patience and support in this matter.
Have a great day,
Edwin.
