Common Provider Class

Hi group. While creating channels, i've realized that all hyperlinks
open a new browser window. I've talked to someone who is familiar with
iPS, and he said that i would need to create a new provider class. This
seems like a lot of work for a small task. Does anyone have an alternate
solution, and if not, does anyone know which provider i should use as a
template to build off (ex: the URL scraper class)? Thanks a lot. - Chris
Austin

If you create a url scrapper channel, you links are stored in some kind of html. in the href add a TARGET argument in the link. TARGET=1. Put this in all your links and they will all open in the same window.WesSystems EngineerNavidec.com303-222-1000 Chris Austin wrote:Hi group.

How to get database connection in common java class

hi friendz,
plz help me...
I am using JDEV 11.1.2.2.0 version.
my problem is I'm writing common java class which can reuse any application.
in this case when im create database connection like this,
String username = "a";
String password = "b";
String thinConn = "jdbc:oracle:thin:@IP:1521:database";
DriverManager.registerDriver(new OracleDriver());
Connection conn =
DriverManager.getConnection(thinConn, username, password);
conn.setAutoCommit(false);
return conn;
but this statement not working in java class.its working only backing bean.
import oracle.jdbc.OracleDriver;
DriverManager.registerDriver(new OracleDriver());
how can i do that??
hope your help
-Harsh-

What is the error message in Java class?
With JDBC 4.0 driver the DriverManager class has added support for the Java SE Service Provider mechanism to the getConnection() and getDrivers() methods using which JDBC drivers may be loaded automatically. The following Class.forName() method is not required to be invoked.
Class.forName(“oracle.jdbc.OracleDriver”);
Only the following is required to obtain a connection.
String url="jdbc:oracle:thin:@localhost:1521:ORCL";
Connection connection = DriverManager.getConnection(url,"oe", "pw");

Service not working after altering Model provider class

Dear all,
I have created a OData service and consumed it successfully. I was able to post data to it. Now after altering the "model class" i.e., adding one property and changing ABAP Dictionary type. After doing these changes but i couldn;t consume the service and get "500 Internal server".
Did anyone experience this problem? Please note i didnt use Service builder(SEGW) to create a project instead i did all manually using Model and Data provider classes.
Please suggest. Your help is appreciated.
Points will be awarded to helpful answers.

Hello Prabaharan,
This is a generic error at client side and there can be multiple reasons for it. This error is from the hub system and only way to check this error is to look into error log and application log in hub system.
Common Problems: property type errors (date, decimal/precision etc.)
But looking at the problem you are facing like Ron suggested you might get 500 internal server error because properties like data and time need to be defined nullable and you might have missed that.
Kindly check and mark fields as nullable if properties you are sending in the payload are null values.
lo_property->set_nullable( ).
Cache clean up is required only when you have done some changes to your model.
See the metadata and confirm if the new property added by you is present. if you are not able to see then do the following.
Try Clearing the cache using /n/iwbep/cache_cleanup and /n/iwfnd/cache_cleanup t-code.
Also clear server cache using /nsmicm t-code as shown below.

Can we use more than one Help Provider class in a same project in ADF11g

Hi All,
There are two help providers i want to use .They are "ResourceBundleHelpProvider","OHW Help Provider"
In adf-settings.xml file
<help-provider>
<help-provider-class>oracle.adf.view.rich.help.ResourceBundleHelpProvider</help-provider-class>
<property>
<property-name>baseName</property-name>
<value>com.symmetry.dashboard.panels.Help</value>
</property>
</help-provider>
if try to register both help providers confliction occurs. Is it possible to register and use more than one help provider.?
Thanks in advance.:)

Thanks Frank,
In adf-settings.xml file
<help-provider>
<help-provider-class>oracle.adf.view.rich.help.ResourceBundleHelpProvider</help-provider-class>
<property>
<property-name>baseName</property-name>
<value>com.symmetry.dashboard.panels.Help</value>
</property>
</help-provider>
<help-provider prefix="RB_">
<help-provider-class>oracle.help.web.rich.helpProvider.OHWHelpProvider</help-provider-class>
<property>
<property-name>ohwConfigFileURL</property-name>
<value>/myHelpset/config.xml</value>
</property>
<property>
<property-name>baseURI</property-name>
<value>http://127.0.0.1:7101/Dashboard_workflow/myHelpset/%3c/value>
</property>
</help-provider>
I differentiated the help providers with the "prefix" attribute in the <help-provider> tag. So now confliction is not occuring between those.
I used this prefix in the "helpTopicId" property of the adf components like "input text box" . I got the result. :)

Re: How do you create and use "common" type classes?

Hi,
You have 2 potential solutions in your case :
1- Sub-class TextNullable class of Framework and add your methods in the
sub-class.
This is the way Domain class work. Only Nullable classes are sub-classable.
This is usefull for Data Dictionary.
The code will be located in any partition that uses or references the supplier
plan.
2- Put your add on code on a specific class and instanciate it in your user
classes (client or server).
You could also use interface for a better conception if needed. The code will
also be in any partition that uses or references the supplier plan where your
add on class is located.
If you don't want that code to be on each partition, you could use libraries :
configure as library the utility plan where is your add-on class.
You can find an example of the second case (using a QuickSort class,
GenericArray add-on) with the "QuickSort & List" sample on my personal site

I'm relatively new to forte and I'd like to know how can you handle utility
type classes that you want to use through out your application? Ideally
what I want is a static class with static methods.
Let's say that I have a StringUtil class that has a bunch of methods for
manipulating strings.
My problem is that we have code that runs on the client and code that runs
on the server. Both areas could use the StringUtil class, but from what I
understand, I have to create StringUtil in a plan and then create a server
object of type StringUtil. The server object will eventually get assigned
to a partition. That's not good since I really want the server object to
physically reside at the server end and at the client end. (Actually, I
don't want a server object, I just want to invoke a static method of a
static class).

Hi Richard,
Your question about "utility classes" brings up a number of issues, all of
which are important to long-term success with Forte.
There is no such thing as a static method (method that is associated with a
class but without an implicit object reference - this/self/me "pointer") in
TOOL, nor is there such thing as a global method (method not associated
with a class at all). This is in contrast to C++, which has both, and
Java, which has static methods, but not global classes. Frequently, Forte
developers will write code like this:
result, num : double;
// get initial value for num....
tmpDoubleData : DoubleData = new;
tmpDoubleData.DoubleValue = num;
result = tmpDoubleData.Sqrt().DoubleValue;
tmpDoubleData = NIL; // send a hint to the garbage collector
in places where a C++ programmer would write:
double result, num;
// get initial value for num....
result = Math::Sqrt(num);
or a Java programmer would write:
double result, num;
// get initial value for num....
result = Math.sqrt(num);
The result of this is that you end up allocating an extra object now and
then. In practice, this is not a big deal memory-wise. If you have a
server that is getting a lot of hits, or if you are doing some intense
processing, then you could pre-allocate and reuse the data object. Note
that optimization has its own issues, so you should start by allocating
only when you need the object.
If you are looking for a StringUtil class, then you will want to use an
instance of TextData or TextNullable. If you are looking to add methods,
you could subclass from TextNullable, and add methods. Note that you will
still have to instantiate an object and call methods on that object.
The next issue you raise is where the object resides. As long as you do
not have an anchored object, you will always have a copy of an object on a
partition. If you do not pass the object in a call to another partition,
the object never leaves. If you pass the object to another partition, then
the other partition will have its own copy of the object. This means that
the client and the server will have their own copies, which is the effect
you are looking for.
Some developers new to Forte will try to get around the lack of global
methods in TOOL by creating a user-visible service object and then calling
methods on it. If you have a general utility, like string handling, this
is a bad idea, since a service object can reside only on a single
partition.
Summary:
* You may find everything you want in TextData.
* Unless you anchor the object, the instance will reside where you
intuitively expect it.
* To patch over the lack of static methods in TOOL, simply allocate an
instance when required.
Feel free to email me if you have more questions on this.

Payload is not available in Proxy provider class

Hi PI Gurus,
I have developed interface Legacy -> PI - > ECC
The payload flown from PI to ECC successfully and i am able too see the payload in Monitor. But the payload is not getting read and not available in INPUT table of Proxy provider class. The no of record is available in proxy provider class.
I am not facing this issue for other interface which was created with similar data flow.
Thanks and regards,
Mohanraj V.

The payload flown from PI to ECC successfully and i am able too see the payload in Monitor.
Do you see successful message in ECC MONI?
But the payload is not getting read and not available in INPUT table of Proxy provider class. The no of record is available in proxy provider class.
Make sure the proxy is active or was re-generated if there were any changes in the data type in XI. At the other hand check the inbound proxy code once again.

Deploying large applications and common used classes

I've got an application containing EntityBeans, statefull/stateless
SessionBeans, and a Webapplication. Every component is packed in a jar File
and all together in an EAR-File as an application.
Those EJBs share some common classes, for example:
EjbA in A.jar and EjbB in B.jar share a Helperclass C.
Where do I put this class C? I try to avoid to put this class C in the
Classpath of the application server. And when I put C in both jar-Files I
got a ClassNotFoundException in one of the EJBs. I'm using WLS 6.0.
Any ideas? Thanx in advance.

FYI, this is fixed in 6.1

6.0 audit provider class location

Hi,
I have been using 6.0 with my application deployed in the default web
application.
I have a class which implements audit functionality which is located
in the classes
directory within DefaultWebApp_myserver/WEB-INF
I am also using that audit class to implement an audit provider class
which is also located in the classes directory within the default web
app.
Now I am trying to deploy the 'default" application as a war.
I am having a problem which I boot wls since it can't find the audit
provider. Is it impossible to use classes within a webapp as the audit
provider. If so, what is the preferred way of deploying the audit
provider class. Should it and all its dependents be in a jar file and
that jar file in the classpath which is used when starting wls?
Will I have a problem if the dependent audit class which is used be
the audit provider is in the classpath when starting wls and also in a
jar file which is part of the war???
Thanks,
Rob

I am experiencing the same problem when calling InitContext() from Ant's JUnit task. I am suspecting that the custom class loader has something to do with this. Does the JSP client in Tomcat has it's own classloader?
The actual initial context factory class is in 'weblogic.jar'. You can open it up with WinZip.

How do I switch user in Common Provider 11.1.1.3 ?

Hi,
After I login to Smartview in Excel using Common Provider 11.1.1.3, I don't seem to be able to change my login ID. It always connects me automatically as my 1st login ID.
how do I switch user in Common Provider 11.1.1.3 ?

I have found that in 11.1.1.3 what John says actually doesn't work every time.
.... very annoying.
If you do the steps John said and it still doesn't work. Do it again. But this time close Excel after you disconnet and then reopen Excel. This will work every time.
Kind of a bug in my opinion but haven't bother chasing after it with Oracle

Error When Trying to POST: Method not implemented in data provider class

Hi Experts,
I have created an Odata Service using Netweaver Gateway Service builder. I am using Advanced Rest Client to test the service. I can successfully GET my data, but I run into issues when I try and POST new data.
When trying to POST, I used the GET method to get the x-csrf-token, and added it to my header. I also updated the body XML with the data that I would like to POST. However, after sending the POST request, I am getting a "500 Internal Service Error" with the xml message "Method '<OdataServiceName>'_CREATE_ENTITY" not implemented in data provider class".
Any help on this would be greatly appreciated. Thanks!

Hi Kelly,
Can you share screenshots of the error? Maybe something wrong with payload :can you share the same also? Did you try to debug it by putting a breakpoint in the CREATE_ENTITY method in the backend? Any luck?

Model provider class and data provider class

please explain Model provider class and data provider class?

Hi,
both MPC and DPC get generated as runtime artifacts.
MPC - This is used to define model. you can use the method Define to create entity, properties etc using code based implementation. you rarely use MPC extension class.
DPC - used to code your CRUDQ methods as well as function import methods. you write all your logic in redefined methods of DPC extension class.
Refer Generated ABAP Classes and Service Registration - SAP NetWeaver Gateway - SAP Library for more information.
you can also refer my blog Let’s code CRUDQ and Function Import operations in OData service! which will provide you clear idea on how to redefine various CRUDQ methods in DPC extension class.

How to get HTTP headers from Data Provider Class?

Hi,
I'm the beginner in SAP NetWeaver Gateway. Using Service Builder I created CRUD OData web service and implemented CRUD operations in Data Provider Class. Data Provider Class has methods like MYENTITY_GET_ENTITYSET, MYENTITY_GET_ENTITY, MYENTITY_CREATE_ENTITY, MYENTITY_UPDATE_ENTITY. How can I get HTTP headers from the methods of this Data Provider Class?

You can do so by using the following code in DPC
Data : Lo_facade type ref to /IWBEP/IF_MGW_DP_INT_FACADE.
lo_facade ?= /iwbep/if_mgw_conv_srv_runtime~get_dp_facade( ).
lt_client_headers = lo_facade->get_request_header( ).
