How to-Transaction across method calls

With reference to the article
"http://otn.oracle.com/tech/java/oc4j/htdocs/how-to-ejb-tx-X-Calls.html", the downloadable example is not available.
Is it possible to recover it ?
Thank yoy in advance

Can't you specify "Requires" in your deployment descriptor for all of these methods involved in the transaction? This should enable the container to manage it for you.

How to restrict repeated method call?

I have a method which fetches data from DB and returns a map.
public Map myDataList(){
returns mymap;
I call this method in the body of another method.
public void myCall(){
myDatalist();
now i want myDatalist() method to be called only once even if myCall() is executed multiple times.

Kapil wrote:
but if i call the method in a static block will it give what i want?
static{
}I'm not quite sure why you're so fixated on only calling a method once. What's wrong with:
static {
   // some set-up code
   while (moreRowsToFetch) {
      fetchAnotherRow();
}But Kayaman's quite right. Explain what you want properly.

Transactional business method is called 4 times on failure

Hi I'm experiencing a strange situation. does anybody have an idea what is wrong or just going on?.
There is a stateful session bean which has a transactional business method called 'apply' to delegate insert/update requests to Toplink which will persist data in database. 'trans-attribute' is defined 'Required'. Toplink registers with the OC4J's external transaction.
when there is an error in commiting the data apply method is called 3 more times (4 times in total).
any idea????
thanks
-Erdem.

Hi Erdem,
This question has been discussed previously on this forum.
[However, when I searched the forum archives to make sure, I couldn't find it -- but I _know_ I had a similar problem _and_ found the answer while monitoring this forum!]
In any case, I think the behaviour that you are seeing is caused by the "max-tx-retries" attribute in the "orion-ejb-jar.xml" file. Here is a resource with some more details:

How can I refresh a calling page on return from a TF activity ?

Hi,
I have a (sounds easy) case where a view activity invokes a BTW with fragments. The called BTF has been declared with isolated data control scope. Inside the BTF some updates happen and when the BTF returns the calling view should display the modified data. The BTF should not be opened as a dialog and the above take place inside a region. There are examples in the Internet for how to implement such case but only calling a taskflow with pages from a dialog.
I tried creating first the Taskflow binding definition [19.10.1 How to Associate a Page Definition File with a Task Flow Activity|http://docs.oracle.com/cd/E35521_01/web.111230/e16182/taskflows_activities.htm#sthref539] , then I set the related operations (Execute, setCurrentRowWithKey, ...) in the Page Definition and invoke the operations inside the “After Listener” Listener (<after-listener>) of the taskflow activity but the binding context is not accessible inside the listener, I get NPE accessing the binding.
After some tests I have found that I can call the Operations using “#data.taskflowdefinition..” but I afraid using this technique because of so many papers stating that this is a bad practice.
Additionally I tested using an invokeAction in the calling page definition page and it works but I prefer “refreshing” the model from the activity (there are many pages calling the same activity).
I am wondering if there is a more elegant solution that I haven’t seen yet.
Thanks for any ideas,
Yiannis

Hi Timo and thank you for your reply,
As far as I know any method executed in the BTF has no effect in the calling page because of the isolated data control scope.
Consider the following layout of a very simple TF diagram. The BTF has "Share data controls with calling task flow" unchecked and "Always begin new transaction"
View --> Method Call --> BTF
Now imagine that a user navigates from the View to the BTF, make updates and finally commits the transaction from a taskflow return activity. The updates are executed inside the "private" BTF's data control scope because of the BTF settings.
Returning to the calling View the user sees stale data from the Data Control of the View, until he re-queries the model.
ADF supports execution of code during the call of the BTF (through Method Call) and also sending and returning parameters from the View to the BTF.
Conversely on return from the BTF there is no handler for executing code (something like "Return Method Call") in order to refresh (e.g. re-query and set current row) the View exploiting the return parameters.
The "After Listener" in the taskflow call activity has not access to the bindings context. Using #{data.bindingTFXXX} I guess that has a risk in a high availability environment for NPE where the http call to the BTF might be processed in a different server than the returning http call so the #{data.bindingTFXXX} might not exists.
The other solution I found using invokeAction with RefreshCondition depends on the returning values of the BTF, bloats the View with Bindings that I would prefer to be in a central place.
Am i missing something in the whole flow above ?

How to handle the call transaction in method of a custom business object

Hello all,
There is a custom report " RPTCORAPP" for approving leaves . As per my requirement i have develop a copy of leave workflow and for approval process i have call "RPTCORAPP" in Custom method of custom object. i have made a transaction for this custom report for approving attendances. I am calling this method though call transaction statement within method.
Problem: while approving the attendance workitem is not disappearing from the portal. Problem is due to call transaction statement.
               once workitem come to the user, user click on it. control goes to the report, which display all the leave to approve on
               the portal.
               If after approving/ rejecting attendance user close the screen.workflow remain in the "process" status.Control wont come back after call transaction statement in the method.
             At the same time if user clicks on back button inspite of closing the screen. it is working fine. workitem disappears from the portal.
How to handle the scenarion. if after approving/rejecting, i want the control to come back to the NEXT STATEMENT after call transactionstatement in my method.
Please help it out........:)

Hi swami,
thanks for reply. but i am not using BDC in my method. iam just calling a custom transaction thriugh statement
Call transaction 'ZHR_APPROVE_CLINOUT'. This transaction directly run the report RPTCORAPP and display all the request.

Using the transaction launcher to call a BOR method to display a PDF

Hello gurus,
I have created a PDF icon and an onclick action to open a pdf, that displays on every row of an assignment block in the actions column, but I do not know the technical process to determine how to get a PDF from the IXOS system from the line selected. (even if I know it depends on an ID attribute of that assignment block) I want to to call a transaction launcher with the url for the pdf in the IXOS that has an ID that identifies which line in the assignment block the user has clicked the pdf icon for (does that make sense?)
In CRM 4, in the collection factsheet assignment block, the link was coded into an XSLT which is then displayed in the GUI and you would have a clickable link for a pdf file in a row in a table. That link would be as follows:
         <xsl:variable name="ev_key">SAPEVENT:?OBJTYPE=<xsl:value-of select="attributes/OBJTYPE"/>&OBJKEY=<xsl:value-of select="@KEY"/>&LOGSYS=<xsl:value-of select="attributes/LOGSYS"/></xsl:variable>
             <a href="{$ev_key}"></a>
This will get the file in IXOS and display it, in CRM 4. In CRM 7, the link is an icon in every line of an assignment block.
Here are some questions I have now for the functional side in the meantime:
1) Can we fetch the PDF in IXOS for each line of an assignment block and have it open? If so, how? Transaction launcher, function modules (like ARCHIVOBJECT_DISPLAY) in the OPTA package? (the package for all IXOS related function modules..)
2) Which URL should I call with the transaction launcher? a URL link to the PDF on the IXOS system?? or sapevent:xxx?
3) Do we have to configure a transaction in the IMG to be launched with the attributes listed there? Do we have to link it to any classes/ objects?
4) Do we have to have the code to the logical link dynamically to call the right PDF for each table line? Is it right to put this code in my event handler?? Usually transaction launchers are just in the nav bar.....
5) Are there any existing examples of this or a similar functionality/ logic that I could refer to, preferably in CRM 7 WebUI?
6) Do you have any code to just display a PDF in a new window? Or prompt a download?
One possible way I thought of would be for me to have a logical link defined in the IMG for the transaction launcher, and have the attributes defined for my BOR object that I would call, and pass it different attributes (eg. objtype, objkey, logsys...) and then return the PDF and display it in the UI in a new browser window by itself. (There is a BOR method for my BOR object named 'display_pdf'!!!!)
What do you think would be the optimal solution here? Does my theory of calling a BOR object with a transaction launcher to display a PDF make ANY sense whatsoever???
Please do not hesitate to propose any potential solution. Any partial answers/ links to wikis/ other threads, anything would be much appreciated.
Thank you in advance.

Hi Any help on this....I am still awaiting the response.
Requirement: My requirement is to launch the SE38 transaction on WEBUI using transaction luncher tool and set the parameter on the selection screen.
Issue: The issue is that I am able to lunch the transaction but unable to set the parameter
Steps Performed:
I want to list down all the steps I performed to launch an SE38 transaction using transaction launcher on the WEBUI
1) Defined logical system in tcode CRMS_IC_CROSS_SYS
-The logical link looks like this
http://<server>:<port>/sap/bc/gui/sap/its/webgui/!?transaction=IC_LTXE&okcode=ICEXECUTE ?sap-client=300
2) Defined URL & paratemeter wherein the request method is "GET", opted for NON-BSP URL
URL link here is
http://<server>:<port>/sap/bc/gui/sap/its/webgui/!?transaction=SE38&okcode=ONLI
-Note: My selection screen okcode os ONLI*
-The logical system ref is provided here
3) Defined the parameter by giving the screen name like for SE38 selection screen name is "RS38M-PROGRAMM"
4) Configured the transaction launcher of type B - URL type and provided the reference of the URL ID, choose the relevant parameter from the drop down and have hardcoded the value, cheked the box "Save Data in Activity Clipboard
5) Added this in the NAvlink/Bus Role etc
6) Now in the handler class of the TL the code looks like this:
IF_CRM_IC_ACTION_HANDLER~PREPARE_DATA_FLOW
__gdc ?=
cl_crm_ui_data_context_srv=>get_instance( gv_view_controller ).
__value
=
'ZC_TEST'.
add_parameter(
   iv_name =
'RS38M-PROGRAMM'
iv_value = __value ).
However, after performing the above steps I am unable to set the parameter. Please suggest where am I missing out on. An early response would really be appreciated.

How to Call Transaction iView that calls RRMXP from Web Dynpro for ABAP

Dear Experts,,
I'm developing an application in Web Dynpro for ABAP wherein I'm supposed to give a link that should open an SAP Transaction iView that calls tcode = 'RRMXP' and I pass the application parameter as QUERY/WBID = <BI query/Workbook ID>.
I tried calling com.sap.portal.appintegrator.sap.bwc.Transaction iView, but it asks for system/application and GUI type parameters. How to pass through the URL?
Any help would be highly appreciated
Regds,
Srini

Hi Wolfgang,,
My problem was that I was supposed to call the BeX Web Analyser ( a BI excel based tool - client installation) on click of a button in my WD-ABAP application. I solved it as follows :
In the portal pcd, I cam across a folder content provided by SAP. Here, you'll find standard template iViews that can be used to call applications ( for which you make iViews). I had to call an SAP TCode : RRMXP so as to call a BI Workbook/Query.
So, I called the standard iView template for sap_transaction_iView as follows :
irj/servlet/prt/portal/prtmode/preview/prtroot/'
           'pcd!3aportal_content!2fcom.sap.pct!2ftemplates'
           '!2fiviews!2fcom.sap.portal.sap_transaction_iview?'
           'sap-config-mode=true&System=BWR3System&TCode=RRMXP'
           '&GuiType=WinGui&OkCode=y&ApplicationParameter=' <appnm> into url.
      l_popup =
         l_window_manager->create_external_window( url = url
                                      has_menubar = ' '
                                     has_statusbar = ' '
                                      has_toolbar = ' '
                                      has_location = ' ').
      l_popup->open( ).
And , it worked.
Any more help pls feel free to revert.

Ejbload() on CMP with transaction = supports - why called before every method?

If an entity bean (CMP v2) has its transaction attrib "supports", why
when a client (ejb/servlet/jsp) calls its business methods does WLS
call ejbLoad() before every method call? Note that the calls do not
occur inside a transaction!
This is not intuitive to me. I would think that ejbLoad() would be
called once when the bean is activated and then all business methods would
access that data.
Note that if you put the entity bean behind a session bean with a
transaction attrib "Required", then the ejbLoad() gets called once no
matter how many business methods are called from the session bean.
This is (obivously) correct.
Why is this relevant? The latest java petstore demo essentially calls
EJBLocal's from jsp (via taglib's) - I guess no different from WLS
EJB to taglib product - where the fine grained getter methods are
called. From what I gather, this means that every one of the jsp
get methods results in a database read! This can't be right!
What am I missing? As above, if the entity bean has "supports"
and is called from a jsp, it appears that ejbLoad()/ejbStore()
would be called for every jsp taglib invocation.

Rob,
Thanks for your reply. This implies that even EJBLocals with fine
grained getter methods should never be used outside a tx scope.Yes, unless you are using Read-Only entity beans which cache data for longer
periods of time.
Even
though you bypass the RMI semantics, you'll be killed by the local tx.
Which to me says that using EJB's from JSP (even via tags) is a bad
idea because each getter method will result in a database read/write,
(unless you go with a readonly EJB as you stated).
Accessing transactional entity beans via tags is probably a bit off. You
could start the tx in the JSP or the tag library, but I don't really like
that pattern much. I prefer making the tags more coarse-grained and having
the tags talk to a stateless session bean which in turn talks to the entity
beans.
>
Unfortunately, I've been seeing some threads on the net advocating
using EJBLocals with tx=supports because one of the most common
patterns has session beans (where you can specify your desired tx)
in front of entity beans (so you're set methods are protected via
the session bean tx),RIght, I think Required or Mandatory is a better choice for the entity beans
here.
but then you can use the EJBLocal (via tags)
on a JSP page (no tx) to view the data via fine grained getter
methods.Other than the performance issues, I dislike this because it exposes the
entity bean directly to the JSP. If I have to go through an interface (the
session bean) to access the entity bean, then I shouldn't have another route
to access the entity bean directly.

As you state, this is a disaster because each getter method
will run in a local tx, requiring a database read/write. Oouch!

First off, I wouldn't recommend that you ever run any EJB with the
'supports' transaction attribute. If you want transactional behavior
use Required, RequiresNew, or Mandatory. If you want to run in an
unspecified tx, use NotSupported or Never.
WLS runs entity beans with an unspecified tx in their own local tx.
That's why you see the reads and writes on the method call boundary.
Your scheme of only reading when the bean is activated could make the
bean's data out of sync with the underlying database. That's acceptable
in many cases, and that's why we have the Read-Only entity bean option.
It gives you exactly what you'd like.

Combination of call transaction & session methods

hi,
how to combine call transaction & session methods in a single transaction.
give me the exact steps to proceed with the above.

Hi Saritha,
Your question is not clear to me but I am assuming your queestion like this
"Providing choice for user for using either call transaction & Session method for uploading data"
When you generate the BDC (Batch Data Communication options define the processing mode for a batch input session) program with SHDB, you can remove a lot of unwanted fields by copying this customize abap include program. It allows you to execute the BDC program immediately without filling up those SAP generate fields. To run background, just run it as a background job.
Execute BDC immediately by replacing the include BDCRECX1
Written by : SAP Basis, ABAP Programming and Other IMG Stuff
                 http://www.sap-img.com
***INCLUDE ZBDCRECX1.
When you generate the program using SHDB, you can replace it
with this if you want to execute it immediately without having
to process it using SM35.
During testing you can used the original include.

include zbdcrecx1.   "After test

How do I keep track of how many times a method is called inside anthr clas?

I am writing code for a program that solves a Knight's Tour. A Knight's Tour is a path a Knight Chess piece can take around the board starting at any spot, touching every square once, and only once. I have to write 2 classes and one is provided. The provided class is encrypted and written by our professor. All I know that it does is simulates the game using the two classes I write and provides a print out and prompts to ask the user which square they want to move to next.
The square class I have to write consists of a constructor that makes a square object that keeps track of its color (white/black) and its status (whether it has been visited, is occupied by the knight, or is free and has not be visited).
The GameBoard class I have to write is what I am having problems with. I am writing a method that determines how many squares have been visited. The previous mentioned class that my professor wrote for me contains a method moveKnight();. The way the program works is that every time moveKnight() is called a square's status is changed to occupied and therefore visited later. moveKnight() will only work if the move requested by the user is a valid move.
SO! My main problem (sorry for all the explaining, just trying to give you all the information) is that I don't know how to keep track of how many times moveKnight() is called by the program. If i can figure this out it should be simple. I'm new to java but i believe...
if(moveKnight() is called)
{count++;} //count is a member variable already initialized
return count;
the moveKnight() is called section within the if() statement is what I am unclear how to do. Please help.
Thanks, Veritas

in your case you want 'count' to be a class attribute rather than a local variable. But yes, incrementing it each time that the method is called will serve your purpose.

How detect method calls that are not already in 1.4

My program is compiled with JDK 1.5 or 1.6 and retroweaved to 1.4.
If I do not take care I may type
int i=65;
Character.isDigit(i);
instead of
Character.isDigit(char)i);
Without casting to char it uses a method that exists only since 1.5 but not
yet in 1.4.
There are a few other methods that had been added since 1.5
Their use leads to NoSuchMethodError on 1.4 clients.
Their usage must be avoided.
How can I recognize them at compile time?
Or has anybody written a tool to check all method calls
whether they already exist in 1.4 ?
If not I would write it myself and probably will use the javap output.
After reading through the docs of java.lang.reflect.Method I guess that
there is no flag telling when a method had been introduced.

there was some discussion on that here:
http://forum.java.sun.com/thread.jspa?threadID=586602
If you use ant, you could also try and configure the src and target properties of javac task:

How to print a method trace to a file (first method called to the end)

I have a tomcat war that I am deploying. I want to use some command line parameter or some tool that will show me a method trace of each method that gets executed.
There is some static initializer in the code that starts everything in the war (the war is not a web app) but simply a process that runs in the background that does stuff.
I want to find out what the first method called in the war is and to locate the static initializer. Having a method trace would do this because this method would be printed out first.
After the static initializer gets called I want to see a method trace of all methods called. Having this printed to a file like Class:Method(params) would be nice.
Even better would be some sort of tool that I could open a trace file with and see method calls in the order they were called.
I tried several Java profiling tools but none of them show me the order (first to last) of the methods called. All I need is to see a method trace from beginning to end.
Any help would be appreciated.

JProbe provided almost everything I needed to see a method call trace. The method graph feature was great.
I have a single static class with a static initializer that runs in a loop but did not know what the class name was (I inherited some code and was told about the static initializer).
So when I fired it up in JProbe it showed me the class running off the root thread. In fact I found another static initializer that was unknown to me and another oddity as well.
The only problem is that the method call graph is collapsed and you need to click [+] to expand every method call.
I am told by JProbe support that there was an "expand all" option in JProbe 7.0 but it is not there in 7.1.
Not sure why they took the time, money and energy to take a needed feature out.
It would be great to have something that did the same thing from the command line or to be able to print a method call trace out to a file but not sure how to do this.

How to use CTUPARAMS in CALL TRANSACTION

How populate and execute methods gets called in UserDefined Action Classes?

In Struts2, if we override methods populate() and execute() , then if we made any request to some Action class which overrides these methods, then how does it look for these 2 methods??
and why populate() method called first and later execute() method????

Thanks for this. Alas, I do not have the source code used to generate the jar file, and I have no means of getting it. I imagine, therefore, that I will not be able to update the manifest file.The manifest file is just a simple text file.
You can get at it by unpacking/repacking the jar file with the jar utility (tar like syntax).
... I assume that classpath is rather like the unix path.It specifies a list of jar files and directories containing java class files (and more).
Is there anything that defines the classpath for each login session and, if so, how do I add to it?As the link I posted says;
you can set a CLASSPATH env.var.

Please help on how to use variables inside a method call

Hello guys,
How's it goin?
Pardon me if you find my question silly, but I am relatively
new in ActionScript 2.0 programming.
I have here a simple problem. It seems I can't use a variable
inside a method call of an object. Here's the code. Please note of
the authParams string variable below.
import AkamaiConnection;
import mx.services.WebService;
var GeneratedToken:String;
var authParams:String;
// Create a Web Service object
var TokGenService:WebService = new WebService("
http://webservice.asmx?wsdl");
// Call the web service method
var myToken:Object = TokGenService.GenerateToken();
// Create an AkamaiConnection object
var connection:AkamaiConnection = new AkamaiConnection();
connection.addEventListener("onConnect", this);
connection.addEventListener("onError", this);
// If you get a result from the web service, save the result
in a variable
myToken.onResult = function(result)
// If you get a result from the web service, save the result
in a variable
myToken.onResult = function(result)
GeneratedToken = result;
authParams = GeneratedToken +
"&aifp=v001&slist=37414/test/Streaming/";
//Call the Connect method of the AkamaiConnection class
connection.connect("cp37414.edgefcs.net/ondemand",true,true,5,true,false,"443","rtmpt",
authParams);
But then, if I use a hard-coded string value in lieu of the
variable, the method call works!
connection.connect("cp37414.edgefcs.net/ondemand",true,true,5,true,false,"443","rtmpt",
"testStringvalue");
I don't know what I'm missing or what I'm doing wrong... Can
somebody help me please? I am using a 30-day trial version of Adobe
Flash CS3. Also, when I Trace output the variables, the values are
there. It just that they can't be read or recognize inside the
method call. Is this a ActionScript limitation?
Thanks so much in advance!

The result param is a returned, “Decoded ActionScript
object version of the XML”. I am not exactly sure what that
means but I have had issues of returned XML values and their
datatype. When I did have these issues I had to cast or convert
into the desired datatype. Try one of the following, assuming the
problem is related to the code that you have bolded.
GeneratedToken = result.toString();
authParams = GeneratedToken +
"&aifp=v001&slist=37414/test/Streaming/";
Or
GeneratedToken = String(result);
authParams = GeneratedToken +
"&aifp=v001&slist=37414/test/Streaming/";
Or
GeneratedToken = result.toString();
authParams = String(GeneratedToken +
"&aifp=v001&slist=37414/test/Streaming/");
