Locking mechanism provided by the Web AS Java

Hi All,
I have a requirement to lock an object for a specific action
with using locks provided and managed by the Web AS Java (i have to use TableLocking API).
I have read about the locking mechanism in "SAP NetWeaver Developer Studio Documentation help" .
I need code samples (how it can be done).
How i should check data availability (is it locked?)?
Thanks.

Browsing the web with JAVA

hi everybody
is there class ,component, whatever in java to browse the web inside java application ,
i mean <i give it an URL and it will browse the page >
thanks alot

The best Java based browser technology I am aware of is from ICEsoft. It's small, fast, and has superb rendering abilities e.g., html 4.01, css 2, etc...

Crawling the Web with Java

Hi everyone.
I've been trying to learn how to make a web crawler in java following this detailed albeit old tutorial: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/
The SearchCrawler class they feature can be found in two parts:
First part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/3/
Second part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/4/
I don't want to copy and paste the code because it is really long and an eyesore if viewing here.
I get a lot of errors when compiling of which I do not understand. The majority of the errors (62 of them to be precise) are "class, interface or enum expected" errors, with the remaining few being "illegal start of type" and "<identifier> expected" errors.
Can someone here perhaps take a look at it and compile it and see if they also get the same errors? I realise it is an old tutorial but there are hardly any detailed resources I can find for java web crawlers.
Thanks.

Odd I can't seem to log into my account. Never mind.
I have used java before, the problem here I suppose is I'm not good enough to spot what's the problem. The code seems fine bracket wise and it has really left me stumped.
If someone code put it in their editor and attempt to compile and see if I'm not the only one that's having a problem.. that would be much appreciated.

No NWDI activity asked while modifying the Web Dynpro java code

Hi,
We have 2 team in our project, one offshore team and one onsite team. We have NWDI also in our landscape.
I have created 1 project in my local NWDS from DTR using create project option from NWDI track , when i do any modification in that web dynpro code once it appears in my local NWDS, its asking for the activity, all this is fine.
But when my offshore team send me this project from offshore (offshore team also working on this project), i go to my local machine under C:\Documents and Settings\user\.dtc\0\DCs\xyz.org\.. (workspace, where all the project folders are created in my local machine ) and replaces the web dynpro project (which i created using create project option from NWDI track ) with the project which offshore teams gave me that is I copy paste the project folder I received from offshore team.
I closed the NWDS and reopened NWDS, i did repair and reload also, but now when i try to do any code modification in that project its not asking any activity at all. So i want to know the reason why its not asking activity at all while modifying the code.
if now i do any code changes, and since no activity is asked, it wont be transported to QA and Prd system.
Can anyone have any suggestion on this..

Hi GLM,
I think you might be right that some files are in read as well as write mode. I went to my local machine and checked the project folder C:\Documents and Settings\user\.dtc\0\DCs\xyz.org\testproject\_comp\.dcdef file , its not in read only mode, that is read only flag was not checked.
I again checked the mode of .dcdef file in other web dynpro projects which are asking for the activity in all those projects mode of .dcdef was read only that is read only flad was checked in .dcdef file. ( I am not sure is .dcdef file only giving this problem that si because of this file not in read only mode I am not asked for the activity)
So could you plzz tell me how to make in read only. when ever i click the read only check box of .dcdef file and reload the project in my NWDS. that read only check box is getting removed. how to do this..
regarding your query, landscape in offshore team and onsite team are different, client has not provided nay access to its landscape to ofshore team so offshore team can not check in / check out the code written by me and same applies to me I can not check in / check out the code written by offshore team , only option is offshore team do some changes in the code and send the project folder via email and I have to deploy in client landsacpe and do further modification.

CONVERT_OTF_2_PDF output can be shown on the web using java sevlet

Hello, all,
I used FM CONVERT_OTF_2_PDF, and I can create a pdf file on my PC by using content in table lines of FM. Now I don't want to create a pdf file on my desktop. I want to pass the value of the table lines to remote java program to show this PDF file on the web. Does anyone knows how do I code it in Java program to be able to show the contents in table lines as PDF? Would you please give an example code? Thank you!

Hi, Dennis,
The contents in the table look like following. (code)

There are two fields (TDFORMAT and TDLINE) in the table, I used following Java code to put them together as PDF. But When I open it as PDF file, it says "the file does not start with %PDF-' . Do you see why
(code)
byte[] pdfstream;
byte[] myout = new byte[]{};
         byte[] tdformat = new byte[]{};
         byte[] tdline = new byte[]{};
         //String myout = "";
         for (int i = 0; i < lt_pdftab.getNumRows() ; i++) {
              JCO.FieldIterator e1 = lt_pdftab.fields();
           while (e1.hasMoreElements()) {
          JCO.Field field = e1.nextField();
          lt_pdftab.setRow(i);
           if (field.getName().equals("TDFORMAT")) {

Standard F4 (search help) in the web dynpro JAVA

Hi,
         I have a small doubt in web dynpro Java. Basically I am an ABAP developer. We created some custom Remote function modules (RFM). Now are able to call RFM through web dynpro JAVA in the portal. We are able to run the RFMs in the portal.
         But we have problem with search help. How can I built the search help for the input fields in the portal using web Dynpro Java.
         Can we bring standard search help (which is exist in R/3) in the portal?

Hi,
I think there is no standered functionality available in WDJava to achieve this functionality like ABAP or WDAbap. but, you can still achieve this using OVS option. to do this also, first you should have an interface which can talk to the R3 system and search the dB as per the query parameters i.e, an RFC which can the desired form of input and give you the desired output.
for more info on OVS, please look into this below links.

The error message is pasted below.
And also how do I run the web service on the browser.
Please help.

If you are getting this error, then you are most likely compiling your code with a different JVM than what is shipped with the application server. Oracle9iAS Release 2 (9.0.2) uses the JDK1.3.1. I got this error when I compiled the code with JDK1.4.0_01.

Reading an xml file in the web services java file

I want to read some data in the webservices file.so i am writing my own xml file through which i want to read data.but i am not able to read xml file from web services file.also , i am not able to put xml file in the .ear file,as there is no such tag in servicegen script through which i can add xml file in the .ear file.
i know in case of servlets,i will specify context-param attributes in web.xml,and i can access those in my servlet.can i do anything like this for webservices,and i am not using any servlets for web services.
kindly tell any solution.

One possible option to parse an xml-file to a flex XML object:
public function parseConXML(source:String):void
                xmlLoader = new URLLoader();
                xmlLoader.load(new URLRequest(source));
                  // Eventlistener: if URL loaded --> onLoadComplete function
                  xmlLoader.addEventListener(Event.COMPLETE, xmlLoadComplete);
            public function xmlLoadComplete(evt:Event):void{
                var xml:XML = new XML();
                 // ignore comments in XML-File
                XML.ignoreComments = true;
                   //ignore whitespaces in XML-File
                 XML.ignoreWhitespace = true;

How to save the image on the web through java code?

Suppose a picture can be loaded on the browser, and nothing
else. If I want to use a jave code to intercept the picture
and save it into a file, what does the code look like? I know
the URL of the picture. Thanks.

Hi. Running your code, I got the following, with the URL as:
String dir = "http://california.biocars.org/viewFrames2.php?";
String fileName = "r=840190844&fn=/data/pub/kb030129_fp_2_001.img&xsize=512&ysize=512&zoom=1&contrast=2048&xcen=0.5&ycen=0.5&wval=0&jpq=100";
String urlName = dir+fileName;
URL imageURL = new URL(urlName);
So something wrong? This output does not look like anything
of a jpeg file. Thanks.

Unable to remove Default Search Provider in the Web Browser

Hi Pros !!!
My Default search provider is automatically updated by VenteeRo Search Provider. When I try to move it it is giving me the following error :
Please find the following image.

This is normal behavior and you could not delete the default search provider. To resolve this problem, add another search provider and make it default, for example you could add Bing as your default search:
http://www.iegallery.com/Addons/Details/16523
When you click add, make sure to set it as default search engine and then open Manage Add-ons again and then delete the current search provider.

Web AS Java 6.40 sp11

Hi All, any help you can give would be greatly appreciated, or indeed point me to the right place if this is not the correct forum, Thanks!
I was installing sp11 from sp0 on an XI 6.40 system, following the sp11 install pdf documentation. I patched the kernel, imported the SAP BASIS 6.40 sp, changed relevant configuration (including updating the jdk from 1.4.2_05 to 1.4.2_07) but when I got to the section on SAP Web AS Java 6.40 support package I ran into an issue. I downloaded the relevent patches and unpacked with SAPCAR, ran SAPInst from the unpacked folders and all was working until it reached the phase "Deploy File System" directly following the phase "SDM Installation/Upgrade". I got an error dialog (Retry/View Log/Stop/Reset) and the log showed the following error:
ERROR 2005-04-04 14:34:51
MUT-02041 SDM call of j2eeenginestartstop mode=manual ends with returncode 16
I also get this error if I run the above call on the command line, together with a java stack, which also appears in the logs:

Severe (internal) error. Return code: 16
I can't find anything in the sap notes about this, or in the other documentation, and am really stuck. I have tried checking if there is another sdm server running and there is not (if I start one I get a different error saying that there is already an SDM server running)
If I really can't work out what to do I will have to go back to the last system backup I did because at the moment the J2EE engine won't even start and I can't get the SAPInst to go forward or backward to where I was before I ran it (e.g under j2ee/os_libs I have a folder "moved_by_sapinst" which remains even when I do a "reset" after the error and the Jlaunch exe has been moved there, and I think this may be why my j2ee server is not starting??)
Many thanks for any help you can give,
Cheers,
Chris

Hi all,
Does anyone else have any suggections as to what I might try? I am still having this issue and have tried everything I can think of, I will keep trying but am running out of ideas.. The fact that the stack trace mentions CVERS table leads me to believe that the Web AS Java sp11 install is maybe looking for a component in my system that is not there, the only 4 things listed in my CVERS table are:
PI_BASIS 2004_1_640 0008 X
SAP_ABA   640        0011 S
SAP_BASIS 640        0011 S
SAP_BW    350        0011 W
Could I be missing something vital or is this a red herring?!
Thanks for any help you can provide,
Chris

How call key Function in WEB Dynpro Java?

Hi,
Somebody know how to call key Function(F1, F2, ... F12) in WEB Dynpro Java to launch and Event?
Thanks in advance.

Hi,
You can WDHotKey property to define the different keyboard shortcuts to enable the user to trigger events with key combinations.
When the user presses the key board shortcut defined as the hotkey then onAction event is triggered.
The keys F2, F3, F4, F5, F6, F7, F8 and F9 are not supported, they call predefined functions provided by the Web Dynpro Framework.
The complete list of supported shortcuts is here:

" APPLICATION NOT FOUND" while deploying Web dynpro java Application

Hi, I am getting a message that "application not found " While deploying the web dynpro java application .......... please give me a solution for this .

Hi Ram,
This error comes generally when your webdynpro project does not have an application. To create an application in your webdynpro project follow the underlying steps:
<Project>->WebDynpro->Applications ---> right click and create New Application.
Follow the steps to create the application.
Now if you create archive and deploy, it will not give you the error again.
Best Regards,
Ravi

Date format problem in web dynpro java

Currently, the date format that gets displayed in our webdynpro java application is MMDDYYYY...i am assuming this is because the web dynpro application has language resource set to en_US as its Current locale in the web dynpro deployed content section. Howver i want it to display as DDMMYYYY. I have changed the default properties in visual admin for web dynpro from en to en_GB however this has no impact what so ever as the current locale is always set to en_US even after the change so am wondering this property is hidden some where else. Now the web dynpro i am talking about is a adobe portal application. Could you give me any pointers as to where else i can look for or how i can change the current locale properly ??
Regards
Kal

The date format in the Web Dynpro Java Application depends upon locale. At runtime WDJ will do the following process to get the current locale for the date format to be determined.
1. First the WDJ Application will check for the locale set for the user in UME.
2. If there is no default locale in UME, then the it will check for the locale in the in the browser which in most cases by default is en-us.
3. If not, then it will check for the sap.systemLocale in the Propertysheet default of Visual Admin
4. If there no locale specified in Visual Admin, itu2019s taken from the WAS JVM
Please check the below SAP Note

Adding a field in Web dynpro java in Travel Request application

Hi All,
How to add a field in Web dynpro java in Travel Request application or can we copy the Web dynpro java application to Web dynpro ABAP and add a field. Experts, Can you please suggest me step by step in resolving the problem.
Thanks & Regards,
Kumar

Hi Kumar,
First, in order to customise the ESS webdynpro Java iViews you need to be aware that, you are about to change the SAP standard iviews. In order to avoid this you can make a copy of the SAP standard one's and then try to customise the copied one's.
Now, you should have NetWeaver Development Infrastructure(NWDI) installed. Once it is installed you should also install the Netweaver Developer Studio (NWDS) on your computer.
Once you have these two installed, you should deploy the ESS Business Package onto the NWDI by creating tracks. There is a cookbook available on SAP Service Marketplace for configuring NWDI for ESS.
Once you have all the above mentioned tools, have a look at the following blog which clearly explains about the procedure of customising ESS iviews.
/people/vinoth.murugaiyan/blog/2007/08/24/essmss-customization-150-make-it-simple
Also check the following Wiki, this might be useful!
https://www.sdn.sap.com/irj/scn/wiki?path=/display/erphcm/employee%252bself%252bservice
I hope this helps. Let me know if you have any issues.
Dont forgett to contribute points if this is useful! All the Best.

PG
