How to display an error Message in Web Dynpro

Hello,
I want to display an error message in Web Dynpro. I'm using this,
IWDMessageManager message = wdComponentAPI.getMessageManager();
message.reportSuccess("<some relevant debug message>");
However, the message is always shown at the bottom of the screen. It is possible to select the location in the screen for showing this object? Or what is the best way for doing this? I've tried to use a Label but I can't set the type (warning, error, info) it's only a message.
Thanks
Regards

Hi,
If you include the UI, it will display at the top of the screen..
Please see below how to create a message in the message editor.
http://help.sap.com/saphelp_nw04/helpdata/en/72/1d6526263ff24995016a152705eab2/frameset.htm
and this is how you access the error message in the application ti display it to the end user

Messages in Web DYNPRO

Hi Gurus,
Can anybody help me to learn different types of messaging in Web Dynpro?
And some links to learn all about messaging in web dynpro.

Dear Veera
There are two ways to define where messages are to be displayed on the screen:
1. The default position of the message area is on top of the page. If this position
is fine, the developer does not have do anything.
2. If a position different from the default message area position is desired,
the MessageArea container UI element has to be used. A MessageArea UI
element can be defined as a sub-element of all other container elements.
Message Handling
In the Web Dynpro application, you can set the way messages are displayed. On
the Properties tab of a Web Dynpro application, message handling can be defined
by setting the radio button to the following values:
Show Message Component on Demand
If at least one message is reported, the message area is displayed in a
group-box style. The message area contains the last message and information
about the number of messages reported in total. In addition, a button is
displayed, allowing the user to display all messages in a list. Messages
related to UI elements are displayed as links. Selecting such a link navigates
to the UI element related to the message.
Always Display Message Component
In addition to the behavior described above, the message area is also
displayed if no message is reported.
Display Messages Without Message Component
All messages reported are displayed in the message area. This area does not
have a group-box style, but it is transparent. All messages are displayed
at once; no extra navigation is required to obtain the list of all messages.
Messages related to UI elements are displayed as links. Selecting such a link
navigates to the UI element related to the message.
Methods for Defining Messages:
In order to report a message, methods of the IF_WD_MESSAGE_MANAGER
interface have to be used. The Web Dynpro runtime automatically instantiates a
class implementing this interface. The reference to this class can be obtained from
the self reference WD_THIS, using the expressions:
r_api = wd_this->wd_get_api().
r_mmanager = r_api->get_message_manager().

HT201209 I bought a movie with the digital copy and it gives me option to redeem it with iTunes, but when I type in the redeem code it shows a message saying: you must insert your digital copy dvd in the computer in order to redeem this code" . The dvd is

I bought a movie with the digital copy and it gives me option to redeem it with iTunes, but when I type in the redeem code it shows a message saying: " you must insert your digital copy dvd in this computer in order to redeem this code" . The dvd is in. WTH? This is especially with FOX movies, I never have trouble with Universal Picture movies.

Thanks for your reply, but you might have misunderstood it a bit. I'm NOT trying to buy a movie. ****, I'm not even in the actual Apple Store, when this happens I'm in the library not the Store part of iTunes.
To clarify - I have purchased a physical copy of a movie which came with another physical copy which contains the digital copy. The digital copy is on the DVD, all I need is just to transfer this file to my iPod Touch, for example, I'm not trying to download it from the store or repurchase it and it's not any gift code that I've received, the digital copy is on the disc. This is the first time ever that I've purchased something on a disc and I'm not allowed to access it because the disc hasn't been purchased within my country.
So again - I'm not attempting any purchase or download any purchased digital copy - it's on a DVD I own physically so... why is even the region of my Store relevant, the code I enter is (as I assume) just supposed to check if it's a legal genuine copy (which it is, as I've said - there are 6 discs in the pack: 3 movies on 3 Blu-rays and 3 DVD containing these digital copies of them). If I own it, I think that's proof enough that I have the right to use it. I just don't get it. I fully agree with you and understand your point if there was any purchase going on here, but it's not, it's just - I put a disc into my computer and I can't access it

How do I rewrite current code for java 1.3

I'm using the code below that is written for java 1.4. I have been told that the company can not push JRE 1.4 to the company, and that I need to write my code for java 1.3. I'm using org.w3c.dom for my create xml, etc.

Are there features of Java 1.4 that you specifically took advantage and are there any particular lines you are having problems with or did you just freak and post it here?
Basically compile it under Java 1.3 and see what complains. I've done several projects that compile under 1.2, 1.3, and 1.4.

SAP Web Dynpro With Java

Hi Guys
A situation at work has forced me to learn web dynpro with java. I already have some experience with the ABAP web dynpro . Now the question is how much "java" do i need to learn to learn sap WebDynpro based on java. Should I first try and get a fair 'hands on' on core java and then shoot for web dynpro or should I take the other approach, that is just learn as much java as is required for web dynpro . Any suggestions?
thanks
sameer

Hi Sameer,
I believe you need not thoroughly know Core Java to begin for Web Dynpro Java but yes, you should have a fair idea about object, class and exceptions that i believe you would already have after working in ABAP. The UI elements can be just inserted into the component by drag and drop and codes correspondly would be auto generated. Only for customization of some functionalities, you will have to write code in Java using APIs.
Just go through the following tutorials recommended by SAP to start over Web Dynpro Java on NWDS.

Tips on how to write efficient java code for java mapping

hi
I do not have much knowledge in Java
Can anybody tell me some tips on how to write efficient and optimised java code to be used in java mapping
Thanks,

hi D'za,

A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the best solution to go for.

Error messages on Web Dynpro ABAP

Hi all!!
I have created a Web Dynpro ABAP which consumes 2 Web Services from XI through Proxy classes.
When a method of a Proxy class from a WS gives an exception, an error screen is automatically displayed, How could I handle this exception and personalize the error message??
Thanks and regards,

Theming Options for Web Dynpro ABAP/Java - Custom CSS

What options are available for creating a custom CSS for WDA? My project is going towards SAPUI5, and they want to apply the same look and feeavl to their Web Dynpro applications.
I know the Theme Designer is an option - but this customer is running on NW 7.3. Obviously to get the WD CSS to look similar UI5, it will require changing all of the WD selectors.
Finally, we have a 7.4 Sandbox. If I build the theme there, is it backwards compatible to their 7.3 landscape?

UI Theme Designer is the only supported way and it is available for NW 7.3 as well, assuming you are up to date on Support Packages. As long as you create a theme with UI Theme Designer the theme will work in any system that supports the same, there might be small functional and visual differences though depending on the SP levels of the source and target systems. SAP recommendation is to always use the latest version available to create (and consume) themes. You could start by using the Cloud version of UI Theme Designer, export and import into your own system. That said your NW 7.3 system needs to support UI Theme Designer to be able to use custom themes created by it.

Example code for java compiler with a simple GUI

There is no question here (though discussion of the code is welcome).
/* Update 1 */
Now available as a stand alone or webstart app.! The STBC (see the web page*) has its own web page and has been improved to allow the user to browse to a tools.jar if one is not found on the runtime classpath, or in the JRE running the code.
* See [http://pscode.org/stbc/].
/* End: Update 1 */
This simple example of using the JavaCompiler made available in Java 1.6 might be of use to check that your SSCCE is actually what it claims to be!
If an SSCCE claims to display a runtime problem, it should compile cleanly when pasted into the text area above the Compile button. For a compilation problem, the code should show the same output errors seen in your own editor (at least until the last line of the output in the text area).

kevjava wrote: 2. Line numbering, and/or a line counter so you can see how much scrolling you're going to be imposing on the forum readers.
Good idea, and since the line count is only a handful of lines of code to implement, I took that option. See the [line count|http://pscode.org/stbc/help.html#linecount] section of the (new) [STBC Help|http://pscode.org/stbc/help.html] page for more details. (Insert plaintiff whining about the arbitrary limits set - here).
I considered adding line length checking, but the [Text Width Checker|http://pscode.org/twc/] ('sold separately') already has that covered, and I would prefer to keep this tool more specific to compilation, which leads me to..
kevjava wrote: 1. A button to run the code, to see that it demonstrates the problem that you wish for the forum to solve...
Interesting idea, but I think that is better suited to a more full blown (but still relatively simple) GUId compiler. I am not fully decided that running a class is unsuited to STBC, but I am more likely to implement a clickable list of compilation errors, than a 'run' button.
On the other hand I am thinking the clickable error list is also better suited to an altogether more abled compiler, so don't hold your breath to see either in the STBC.
You might note I have not bothered to update the screenshots to show the line count label. That is because I am still considering error lists and running code, and open to further suggestion (not because I am just slack!). If the screenshots update to include the line count but nothing else, take that as a sign. ;-)
Thanks for your ideas. The line count alone is worth a few Dukes.

Web Dynpro without Java stack?

Hello
a simple question : Is is possible to deveop and run Web Dynpro applications on a system with no Java stack? It is a ECC 6.0 system.
Thanks
A.

Hi Aleksandra,
Yes it is posible to develop and run Web Dynpro applications without Java Stack.
For Web Dynpro for ABAP :- Java stack not required, you can do with SAP System T-Code - SE80 if Web Dynpro Component available in your sap system.
For Web Dynpro for Java :- You must require Java Stack.
Hope this will helps you.
Thanks

Web Dynpro ABAP - Java stack required?

Hey everyone,
We are currently planning an upgrade to ECC 6.0 and Netweaver 2004s. A source of debate during this planning has been whether or not to install the Java stack in our upgraded system.
I'm an ABAP developer, so I'm really looking forward to using Web Dynpro ABAP. Does anyone know if the Java stack is required to effectively use Web Dynpro ABAP? It seems like the two should be independent...but I just want to be sure.
Thanks in advance!!
Chad

No, you do not need the java stack to run WDA applications. It runs purely on the ABAP stack. You can develop your WDA app in SE80 and run it. It will run in a browser from the ABAP stack. If you have a portal, then you know that this runs on the java stack. Also, your portal is probably not running on the same box as your backend ERP system. If you running a portal, I would suggest installing both the java stack as well as the ABAP stack for you portal to run on. Then you will be able to use WDA to create applications to run in your portal.
So to sum up, the portal runs on the java side, if you have both stacks running under your portal you can development WDA and WDJ applications, which both can run on that same engine. To answer you question, you DON'T need the java stack to develop and run your WDA application, but if you want it to run in a portal, then you need a java stack to run the portal on top of. This can be a completly separate box and a standalone java stack. Did I confuse you even more?

How to Pass Java Objects between Web Dynpro and Java SAP iViews

Basically I have an SAP web dynpro iView that I do stuff with and I want to pass an object to another iView which is just a regular Java iView. From what I've read and tried, I can't just stick something in the session object and hope that the Java iView can pull it down the other end. I had a dream that it was possible (seriously).
Anyway, are there any possible solutions around? Please advice and share you throughts. I will try to dream about it again tonight and see if its really gonna work this time.
thanks for your help in advance

There is no easy way you can pass objects other than those supported by express such as String, map, list etc.
Though not advised, you can create a class with static variables to handle the storage of such java objects during transition between form and workflow. You will need to somehow identify the objects uniquely .

New to Programming, need your help with writing code for java in Xcode.

Hey everyone! Sorry if I sound like a total idiot here with a bunch of developers but I could really use your help. I am in college and having a bit of problems with my intro to programming class. The class is entirely Java based and so, after having to use dos windows on my grandpas crappy laptop I found out about xcode. I downloaded and installed it but I am having problems seeing where exactly it is that I am to write my code for a normal java application. Any help would be greatly appreciated! I wrote it on the bottom of a bunch of code that looked strange to me. For relatively simple java programs I chose the java application template. Is there something here that I missed?

The Java Application project template looks like it sets up an application and some kind of starting UI using Swing/AWT. I didn't look at it too indepth, but if you are in an introductory course this might be more than you need to complete your assignments. There doesn't seem to be blank Java template, so I don't know what you should use. Perhaps just a blank project you add your .java files to.
To answer where to write code, you would write it in your .java files under the /src folder. Execution begins in
public static void main(String args[]) {}
in YourAppName.java, then creates an object based on your application class, and runs the code from there to display the UI.
