How to implement Constants of JheadStart Applications

Hello JheadStart Team
we want to gather all constant values of JHS application in one xml file without having to hardcode them in different sections of application (model or view) , and accessing values by binding them anywhere required . Can you give me have any comment or guidline for better decision?
thanks you

We have some constant values that we want to use them in both viewcontroller and model project such as "where clause values" in model or "Query bind paramter " in view controller . in other word we have expression such as "branchcode=:mybranch" that we want alway read :mybranch value from a file (eg xml) file .
Can you give me best practice or proper solution for this matter.
Thank you

Best practices on how to implement logging in custom application

In the Enterprise Manager it is possible to display/browse the content of different log files generated by the application server modules.
I have some custom web applications which currently use the log4j framework to write to log files. Is it possible to make these log files accesible for the Enterprise Manager ?
Or what is the best practice on how to implement logging in custom applications which can be browsed in the Enterprise Manager (I do not want to use system.out)

I thought that this could be done. An ex- colleague did this - but he didn't tell me how to solve this.
But as it just took 10 minutes to solve this I believe it's fairly easy.

How to implement multiple Value Helps within the same Application ??

Dear Experts,
I want to implement multiple value helps in the same view.For that I have declared exporting parameters of type 'wdy_key_value_table.' within the component controller for each of the value helps.While I do activate and test the application I get the following error :
The following error text was processed in the system HE6 : A row with the same key already exists.
The error occurred on the application server hsdnt24s11_HE6_00 and in the work process 4 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: VALUESET_BSART of program /1BCWDY/9VSHJWRNR0EZPKFT3ZKC==CP
Method: IF_PO_VIEW1~VALUESET_BSART of program /1BCWDY/9VSHJWRNR0EZPKFT3ZKC==CP

I dont know how to implement multiple value helps.Need your help on this.

Mamai.

Hi
Hint is : A row with the same key already exists it means , It is assigning the same value/Key to row and you are calling it at WDDOINIT so it giving error at the time of initialization .
Better way to do the coding at some event in view OR if not possible than just execute the first value help in wddoinit later clear all the value before gettig the other Value help. Code it at WdDoModify View to get its run time behaviour.

How to implement google search in portal application

Hi,
I am using "http://api.google.com/GoogleSearch.wsdl" file to implement google search in portal application. but i am not able to get the search result. how to implement google search. is this "http://api.google.com/GoogleSearch.wsdl" is vaild now ?. how to achieve the soultion.
Regards,
Shanthakumar.

Hi Shanthakumar,
The "GoogleSearch.WSDL" is no longer available as google has replaced it with the new AJAX based searching and they have eventually removed it from public use as well from 7th September 2009. So, I would imagine you would not be able to use the earlier WSDL file for google search. You might have to look in using the new "AJAX Search API". For more information have a look the following links. You can notice "No Longer Available" at the top of the page.
http://googlecode.blogspot.com/2009/08/well-earned-retirement-for-soap-search.html

I hope this helps you.

How to Implement a Time Limit Feature in an Online Test Application ?

I am creating an Online Test application. The time limit can be stored for a Test in the database.
How to implement a time limit such that when the test is started (user clicks on the Start button to go to the fragment containing the Questions) the time left is shown and the test ends (goes to home page) when the timer reaches zero.
Thanks

Hi,
timestamp is a date and thus cannot be used directly to determine seconds passed. So what you need to do is to build the difference between a saved time stamp and the current time.
http://docs.oracle.com/javase/1.4.2/docs/api/java/sql/Timestamp.html
So if you have two time stamps, then calling getTime() on each and building the difference gives you a value, which is millisecond. So to get this to an int value you divide it by 1000

How to implement webdynpro application into portal.

HI all
I have developed a Web Dynpro application (for eg: SAP online registration test for tech ED 2007). how to implement it into portal..
I mean i want it as a role to displayed in my portal.
what tempalte i have to use while creating iview..

please give me step by step solution for this..
Thank&regards
Gayathri

Hi,
Assuming you have deployed your webdynpro, you simply need to create webdynpro iView in portal.
Check this simple help documentation on how to create the iView
http://help.sap.com/saphelp_nw04s/helpdata/en/13/b4dc4281de2878e10000000a155106/content.htm
Once you have created the iView, create a role. Set the entry point of the role to yes.
http://help.sap.com/saphelp_nw04s/helpdata/en/f6/29cf3d4f902d10e10000000a114084/content.htm
Right click on the iView and assign the iView to the role.

How to implement start & stop ai triggers when # scans unknown

I can't seem to find an implementation example for this application.
Some are close but seem to have a big gap on close examination.
The application is to log an unknown number of samples for a
single rotation of a variable speed drum. The drum is connected
to a tachometer which generates 1 pulse per revolution and is the
trigger source.
The user will initiate the data collection and only a single
rotation's
worth of data need be collected and displayed.
The board is a PCI 6111E sampling a single input at ~2 Megahz.
All the examples I've found using a start and stop trigger depend
on knowing how many scans to acquire.
Is there any way to get around that? It seems so simple to
have a
start and stop pulse, a scan rate constant, and just get
the data out of a buffer. But it does not seem to be that simple
or am I missing something here?
There is also an issue with the identical tach signal being used
for both the start and stop trigger. I think that can be gotten
around by using a divide by n counter and feeding that to
trigger config vi but if anyone has any suggestions for that,
they would be greatly appreciated.

How can I interface a Java application which is not running under NetDynamics, to use the EJBs in a NetDynamics application?

One of them uses Enterprise Java Beans implemented with a SUN NetDynamics application server. The other is a straight Java application. Ideally I want the second application to remotely invoke methods on the existing Java beans, so the existing business logic will not be duplicated.
This would seem to be simple, but NetDynamics appears to substitute some proprietary code for part of the EJB interface, and it is not immediately obvious how to let "foreign" java programs access the beans.
I would appreciate it if anyone is able to provide any information on how to achieve this. If you know of any sample code that I could look at, that would be a help too. This may (or may not) be known to SUN as a "stand alone java client".

hi,
can someone help me how to implement logging for method entry parameters and
method exit return value.
can someone help me how to use log4j and integrate it to the method entry
logging and method exit logging.
Here what i need is without writing the log statements for the method entry and
method exit i need to log it to the file
along with other log4j debug statements i provide in the file.I should be able
to configure whether to enable/disable the logging
for method entry and method exit. In method entry i should be able to log the
parameters the method take and in method exit
i should be able to log te return value to the log file, before the method is
returned to the callee.
i hope i am clear
Thanks in advance.

How can i built a java application using java debug class on Log4J

Hi,
As java API support the MethodEntryEvent, using which I can get the automatic logging statements when the method is entered or exited as HelloExample.main(with argument type).
Where HelloExample is the class name.
Main is the method entered with its argument types.
In some cases I have the o/p as
-- VM Started --
====== main ======
main -- HelloExample
callerMethod -- HelloExample
====== main end ======
-- The application exited --
By using Log4J is there any possibility of getting these sort of o/p along with the loggers supported by Log4J. i mean to say can i built an java application which supports the MethodEntryEvent and MethodExitEvent from java API and also uses the Log4J debugging. I took an e.g. trace example, which (in J2SE 1.4.x or 5.x) will be found in $JAVA_HOME/demo/jpda/examples.jar and unpacking it by
jar -xvf $JAVA_HOME/demo/jpda/examples.jar i found the com/sun/tools/example/trace/Trace.java and passed the class constructed with logger taken from Log4J. In this case the logging message is displayed on the console. As per the requirement i need to transfer the whole o/p to an output file along with Log4J logger statements. in this case i should not give any command in the cosule except compiling and executing the programme. the programm also should able to run without the main() as i need to integrate Log4J with an application and the code must me application server independent. i need the output as i got using MethodEnteryEvent (shown as above) in case of java application built using Log4J.
Can any one help me in this regard. can any one give me some suggestion or any programme of this sort. All suggestions are welcomed.
Thanks & Regards,

How to implement Strategy pattern in ABAP Objects?

Hello,
I have a problem where I need to implement different algorithms, depending on the type of input. Example: I have to calculate a Present Value, sometimes with payments in advance, sometimes payment in arrear.
From documentation and to enhance my ABAP Objects skills, I would like to implement the strategy pattern. It sounds the right solution for the problem.
Hence I need some help in implementing this pattern in OO. I have some basic OO skills, but still learning.
Has somebody already implemented this pattern in ABAP OO and can give me some input. Or is there any documentation how to implement it?
Thanks and regards,

How to implement a single sign on feature using java.

Hi,
I have a question like , How to implement **single sign on** feature in java without using any third party framework or tool like LDAP or any other which is available in the market.
Actually the situation is i have all security information into the table and those information is used for single sign on . If a user logged in from a jsp loging page all the security role should be assigned to that particular user.
We can do this using LDAP but i am not supposed to use the LDAP or any third party tool . I have to write a java class for that .
please suggest me the method , how to implement this in a web application.
Edited by: Rakesh_Singh on Mar 19, 2008 11:55 AM

you could setup a token that specifies a user is authenticated. other applications that u want SSO can check for existance of this token
if it is HTTP - you can save the token as a cookie and downstream apps look for this token
yr code needs to validate that the token/cookie was indeed a valid one and not subject to man-in-the middle attack.

Manuel,
When mapping relations to pre-defined schemas using application identity,
you must use the '<fieldname>-data-column' extension syntax discussed in
http://www.solarmetric.com/Software/Documentation/2.2.6/manual.html#metadata

Additionally, in general, you should not have foreign key fields declared in
your java code as well as relations to other objects. For example, in
PermissionGroupMap, you should just have a relation to UserGroup, and no
groupOid field -- the foreign key information will be handled by JDO, and
should not be user-accessible except through the UserGroup relation.
So, something like this is probably more like what you want (I've removed
some fields for brevity):
<class identity-type="application" name="UserGroup"
objectid-class="UserGroupKey" requires-extent="false">
<field name="groupOid" null-value="exception" primary-key="true">
<extension key="data-column" value="GROUP_OID"
vendor-name="kodo"/>
</field>
<field name = "permissionGroupMap">
<collection element-type="PermissionGroupMap"/>
<extension vendor-name="kodo" key="inverse" value="userGroup"/>
</field>
</class>
<class identity-type="application" name="PermissionGroupMap"
objectid-class="PermissionGroupMapKey" requires-extent="false">
<field name="permissionGroupMapOid" null-value="exception"
primary-key="true">
<extension key="data-column" value="PERMISSION_GROUP_MAP_OID"
vendor-name="kodo"/>
</field>
<field name="userGroup" null-value="exception" primary-key="false">
<extension key="groupOid-data-column" value="GROUP_OID"
vendor-name="kodo"/>
</field>
</class>
public class PermissionGroupMap {
java.math.BigDecimal permissionGroupMapOid;
// this is not needed: java.math.BigDecimal groupOid;
/** relationship fields **/
UserGroup userGroup;
public class UserGroup {
java.math.BigDecimal groupOid;
/** relationship fields **/
ArrayList permissionGroupMap = new ArrayList();

How can represent a 1-n relation in a .jdo file without adding more fileds.
Here is my .jdo implementation

How to implement this attribute ?

Hi,
I've this problem.
In our application to control healthcare expense I've implemented a cube with 6 dimensions. (here for who knows Italian : http://www.oracle.com/global/it/customers/profiles/profile_77.html )
The biggest dimension is the "patient" one, with 1.500.000 units at 5th level, grouped in geographic aggregates, until the entire city at highest level.
Now customers wants to have the possibility to select patiens with chronic disease from these. There are about 500 kinds of chronic diseases.
Every patient can have no one, one, or (and this is the problem) more then one of these chronic disease.
How to try to implement this? as a new dimensions or as an attribute ?
I've thought that best way is to introduce a new (chronic diseases) dimension, to have a way to select one or more of these diseases at all levels of patient dimension.
I'm asking how to solve the problem that a single patien can also have more than one disease.
Is there any way to implement this ?

thanks to everyone for the answers
I've some questions.
to olapworld:
have you any sample code to show me how to implement the dimensionalized valueset and the customizations needed ??
to scott:
I think I'm not understanding your suggestion:
my target is to add the "ilnesses" selection to other ones. The most important cube of my applications analyze
healthcare expenses from six dimensions. Customer wants analyze cube "adding" a way to select only "ilnesses" patients and elvaluate their expense.
I'm in doubt becouse a patient can also have more then one ilness, so I can't simply add a "ilnesses" dimensions to the cube and mapping it to an "ilness_id" in the fact table.
How can the two dimensioned cube to help me in this ?
to Rafalm1:
in any case, implementing Count(Distinct patient) would be useful for me, to have a way to count the number of patients who had a healthcae assistence. Can you suggest me how to implement this ?
