Let ApplicationContext Pick up Properties by Runtime Environment

In one of my recent projects, I needed to point to different data sources by run-time environment.

In the web container, we can define jndi data sources. But what about in the batch environment?

I have heard of something like dummy jndi but I have some problem trying to understand it. So I figured out another way.

In the applicationContext.xml file, I used propertyConfigure to define location at classpath:application.${runtime}.properties.

Then I created two properties file, application.development.properties and application.production.properties.

Then in the applicationContext.xml file, I just pick up the properties.

Then in the command line, I just need to specify the "runtime" variable by using -Druntime=development or -Druntime=production.

Done.

Note: if in applicationContext we need a value "\\abc\aaa", we need to define it in the properties file as "\\\\abc\\aaa".

Portal Drive

A nice tool to map KM folders into Windows PC/server.

Download path:

SAP Software Download Center -> Support Packages and Patches -> N -> SAP NetWeaver -> (Your SAP Portal Version/Release) -> Entry by Component -> Frontend

I downloaded 4.4 and 4.5. I installed 4.5.

Check if WebDAV is enabled. System Administration -> System Configuration -> Knowledge Management -> Content Management -> Protocols -> WebDAV

The Enable WebDAV Server should be checked on.

Configuration url

http://:57100/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/

Done.

Unlock a document in KM

EP Upgrade from 7.0 SP 18 to 7.01 SP 8

After the upgrade, I found a new deployment would only be effective after the SAP reboot.

Download NetWeaver Developer Studio 7.0

To download NWDS 7.0 or 7.01, search by JIDE* on SAP support portal.

SAP - How to make IScheduleTask configurable

cc.xml co.xml

SAP - dist/PORTAL-INF/config

We are not using NWDI. We use a third-party source code management system.

The dist/PORTAL-INF/config folder was checked into the repository. Later when we did a quick PAR upload, NWDS complained not able to delete the folder.

Tried to find a way to prevent it being checked in, but found no solution.

Finally I found if I define this folder as Derived, it won't give me any trouble.

Some small consideration when design web applications

Sometimes I think to myself, what makes web application different from others? I find a real case when I review a real application.

This application has an edit page, on which user can select "Y" or "N" from a drop list. It also define keys for "Y" and "N" in a message properties file and this application is designed for English only.

I think there are at least two small places that the designer can do better.

1. use radio button instead of drop down list, this saves one click.
2. still put real messages in properties files but no need to treat a "Y"/"N" choice as a real message

The reason to put real messages in properties files even for an English only application is to allow business easily change those messages during the whole application life cycle. It will still be an application level change, but you would have much more confidence that a regression test will not be needed.

SAP Portal - Multiple Node Installation of a KM Scheduler Task

In an environment with more than one CM system, you must assign one (any) CM system in the cluster to each scheduler task.

Do not assign a scheduler task to more than one CM system at the same time. In the configuration of a scheduler task, there must be only one entry in the CM Systems parameter.

To balance the load, we recommend assigning all scheduler tasks to one dedicated CM system that runs separate from the load balancer. This separation removes the load caused by running the scheduler tasks from the other nodes and makes them available solely for your users.

Have fun! World Cup is coming.

Last month a world wide telephone survey was conducted by the U.N.

There was only one question asked: "Would you please give your honest opinion about solutions to the food shortage in the rest of the world?"

This survey was a HUGE failure because of the followings,

1. In Eastern Europe they didn't know what "honest" meant.
2. In Western Europe they didn't know what "shortage" meant.
3. In Africa they didn't know what "food" meant.
4. In China they didn't know what "opinion" meant
5. In the Middle East they didn't know what "solution" meant
6. In South America they didn't know what "please" meant
7. In the USA they didn't know what "the rest of the world" meant
8. In Australia they hung up as soon as they heard the Indian accent.

SAP Portal - Internationalization on Room Directory

NetWeaver Collaboration with Enterprise Portal 7.0.18 only supports English and German.

To internationalize it, download com.sap.netweaver.coll.appl.ui.room.par and add

UIRoomdirectoryConsts_es.properties to support Spanish and
UIRoomdirectoryConsts_fr.properties to support French.

Then redeploy the par to EP.

SAP Portal - Promote KM Changes to Next Stage

As I said in my previous posts, we created a new XML form, a couple of new predefined properties, and a new filter. Now we need to promote these changes to next stage.

Portal Content

• create a transport package and add the changed iView into the package

KM Configuration

• create a configuration archive and add the following into the archive
• KM->CM->Form-Based Publishing -> Forms Availability ->Folder Settings, the new folder-form setting
• KM->CM->Global Services->Property Metadata->Properties, the new metadata
• KM->CM->Global Services->Property Metadata->Groups, the new metadata group
• KM->CM->Global Services->Property Structures->Property Groups, the new property group and the all_groups
  
• KM->CM->Global Services->Resource List Filters, the new resource list filter
• KM->CM->Repository Filters, the new filter class
• KM->CM->User Interface->Settings->Layout Set, the new browser

XML Form

• copy the new xml form to next stage

Create a FM_News_Form

SAP Portal - Use Properties in XML Form

I found almost zero documents on this subject. I figured it out finally with some common sense and some luck.

I configured some predefined properties to my KM documents. After it, I needed to create a XML form and use these properties for users to create such documents.

Here is what I had done.

1. Open an existing News form and save as my own project, called FM_News.
2. At the left side, select the Data Model, right click on Properties and select Reload Properties
3. At the editor area, add a label ABC, add three check boxes A, B, and C
4. Add a label DE, add two radio boxes, D and E
5. Define A - Caption A, Name ABC, Value A, Property Reference /Properties/default:ABC
6. Define B - Caption B, Name ABC, Value B, Property Reference /Properties/default:ABC
7. Define C - Caption C, Name ABC, Value C, Property Reference /Properties/default:ABC
8. Define D - Caption D, Name DE, Value D, Property Reference /Properties/default:DE
9. Define E - Caption E, Name DE, Value E, Property Reference /Properties/default:DE
10. Note: check box for multiple selection and radio box for single selection, XML Form Builder may warn you to use Combo Box instead, ignore it.
11. Save and generate.
    

SAP Portal - XML Forms Builder

This builder is under the Content Management tab of Content Manager role.

After every change to the form, save the project and generate the project.

This generation, my understanding, is to publish the change to portal.

To move the change to QAS or PRD, copy its xml files from \usr\sap\[sid]\SYS\global\config\cm\etc\xmlforms to QAS or PRD servers.

SAP Portal - How to Configure Predefined Properties for KM Documents

We use KM Navigation iView to broadcast news which are posted in KM repository.

We need to separate them by Field and by Language.

2. New
3. Global Services -> Property Metadata -> Properties
4. New - Unique ID = NewsGroup-Field, Property ID = Field, Namespace Alias = default, Group = NewsGroup, Mandatory = Yes, Multi-Valued = Yes, Maintainable = Yes, Default Value = Field1, Allowed Values(csv) = Field1,Field2,Field3
5. New - Unique ID = NewsGroup-Language, Property ID = Language, Namespace Alias = default, Group = NewsGroup, Mandatory = Yes, Multi-Valued = No, Maintainable = Yes, Default Value = English, Allowed Values(csv) = English,French
6. Global Services -> Property Structures -> Property Groups
   
7. New
8. Global Services -> Property Structures -> Property Groups, select all_groups and Edit
9. Add the newly created NewsOptions to Group Items and OK
   
10. Content Administration -> KM Content, select a document and open its Details
11. Settings -> Properties -> NewsGroup tab
12. Done
    

SAP Portal - Namespaces
