Showing first tab always in a ADF panelTabbed

Oracle ADF panelTabbed component has the capability of remember the last Tab that the user keeps opened.

When the user get back to the page or taskflow that contains the af:panelTabbed, the last tab opened will be shown instead of the first tab.

If you want to show always first tab as "opened", there is a couple of parameters at the af:showDetailItem that will help us.

This  is a sample code that will make the trick:

<af:panelGroupLayout id="pgl1" layout="vertical">
  <af:panelTabbed id="ptab1" position="above">
    <af:showDetailItem text="First" id="sdi1" persist="disclosed" disclosed="true"/>
    <af:showDetailItem text="Second" id="sdi2" persist="disclosed" disclosed="false"/>
    <af:showDetailItem text="Third" id="sdi3" persist="disclosed" disclosed="false"/>
  </af:panelTabbed>
</af:panelGroupLayout>  

 Check ADF Tag Library

• af:panelTabbed
• af:showDetailItem

Big thanks to my co worker María for finding the solution :-)

Validate check-in form fields with Javascript

At one of my current projects we faced the problem that the dDocName field was filled with no common characters by the user.

For example they insert spaces and letters (like áéíóú). This kind of contentID was breaking the indexer process of UCM.

Most of you will tell me to use the AUTO_NUMBER property of content server, but on some type of content, the user have to insert a specified dDocName for our SSXA Web project.

To prevent contentID like "BIOGRAFÍA CATALÁN", we developed a custom component that performs a JS validation before check-in process.

For the validation I've created a REGEX expresion that allows only letters, numbers and underscore.

This is the code inserted in the custom-component. As you see, this will "include" all system validations with the <$include super.custom_schema_validation_script_post$> sentence.
After that, starts our custom validation, we only have to return "false" if we want to cancel the check-in process.

<@dynamichtml custom_schema_validation_script_post@>
<$include super.custom_schema_validation_script_post$>
<$if ((dpAction like "CheckinSel" or dpAction like "CheckinNew" or dpAction like "Update"))$>
if (document.Checkin != null && document.Checkin.dDocName != null)
{
var name = document.Checkin.dDocName.value;
if(name != null && name != '' && name.length > 0)
{
 var rgx_docname = /^[A-Za-z0-9_]{1,30}$/;
 
 if (rgx_docname.test(name))
 {
  vstatus = "Ok";
 }
 else
 {
  vstatus = "Error";
  alert("Error: You cannot use non-ASCII characters for ContentID");
  return false;
 }
}
}
<$endif$>   
<@end@>

Using WebCenter REST API from Java

Most WebCenter services are available over REST access. In this example app we will try to connect to our development Spaces instance and get the list of spaces for the user.

The REST API supports two kind of different authentication, depending where you use the Java code. If you are creating a taskflow to be deployed on same domain of the spaces node, you should use "OIT" auth, this kind of auth does not need the user password on each request to the server.

Instead, if your code is outside of the weblogic domain, you must send (user + password) on each request.

This sample app have a boolean flag to enable "development-mode" that means connection from outside of weblogic domain (for example my local JDeveloper).

Keep in mind that on each request you should have the URL access to your REST API, to generate that URL you need before the userToken.

//Get the client connnection
RESTUtils rest = new RESTUtils();
rest.setDevelopmentMode(true);

//Get weblogic user token
String userToken = rest.getUserToken();

//Creation of endpoint URL

//Sample URL: http://owc:8888/rest/api/spaces?utoken=FMgUQjBKZ96NGgwGdlZrX-WJACJ4_w**
URL endpoint = new URL(RESOURCE_INDEX + UTOKEN + userToken);

//Establishing connection
HttpURLConnection connection = rest.getConnection(endpoint);

This is the sample output of the app after executing the class WCSpaces.java

5-sep-2012 10:34:33 webcenter.rest.RESTUtils getUserToken

As you see, both "displayName" of the spaces are obtained.

Disable component resizing in Oracle Composer

When using Oracle Composer sometimes apper an icon under componentes that allows resizing in runtime.

Check this image

As you see, appears an icon at the botton-right of the component with an appaerance of a triangle. This icon/behaviour can be disabled editing TaskFlow properties and disabling the option.

This action should be performed every time we add a new TaskFlow so is quite annoying.

To disable all resizing behaviour in our portal we have to modify our adf-config.xml file including this lines

  <customizableComponentsSecurity xmlns="http://xmlns.oracle.com/adf/faces/customizable/config">
    <enableSecurity value="true"/>
    <actionsCategory>
      <actionCategory name="personalizeActionsCategory" value="true"></actionCategory>
      <actionCategory name="editActionsCategory" value="true"/>
      <actions>
        <action name="showResizer" value="false"/>
      </actions>
    </actionsCategory>
  </customizableComponentsSecurity>

After this modification, the components won't show the "resize" icon any more.

Configuración REST para WebCenter Spaces (PS3, PS4)

WebCenter Spaces incluye una API REST para consumir sus servicios, esta API es necesaria para alguno de los siguientes casos:

• Utilizar la aplicación de iPhone / iPad
• Utilizar datos de Spaces desde una aplicación WebCenter Portal
• Subir recursos a Spaces (PageTemplate, Content Presenter Templates, etc...)

Para mi ejemplo voy a configurar mi máquina virtual (owc) para que permita este tipo de conexiones.

Es importante indicar que esto solo es necesario en WebCenter PS3 y PS4, en la nueva PS5 ya viene configurado de serie.

Probamos a conectar a la siguiente URL:

• http://<host>:<port>/rest/api/resourceIndex

En mi caso: http://owc1:8888/rest/api/resourceIndex





Como se puede observar no tenemos acceso, realizaremos los pasos que incluye la documentación oficial, que consiste en:

• Configurar Identity Asserter
• Configurar el servidor de almacenes de credenciales.

Pasos a seguir

1.- Creamos el keystore

cd /oracle/jdk/bin (cualquier directorio Java)

./keytool -genkeypair -keyalg RSA -dname "cn=spaces,dc=oracle,dc=com" -alias orakey -keypass welcome1 -keystore /home/oracle/default-keystore.jks -storepass welcome1 -validity 1064

./keytool -exportcert -v -alias orakey -keystore /home/oracle/default-keystore.jks -storepass welcome1 -rfc -file /home/oracle/orakey.cer

./keytool -importcert -alias webcenter_spaces_ws -file /home/oracle/orakey.cer -keystore /home/oracle/default-keystore.jks -storepass welcome1

./keytool -importcert -alias df_orakey_public -file /home/oracle/orakey.cer -keystore /home/oracle/default-keystore.jks -storepass welcome1

2.- Lo copiamos a (Todos los manejados)

cp /home/oracle/default-keystore.jks /oracle/middleware/user_projects/domains/dev_domain/config/fmwconfig

scp /home/oracle/default-keystore.jks oracle@owc2:/oracle/middleware/user_projects/domains/dev_domain/config/fmwconfig/

vi /oracle/middleware/user_projects/domains/dev_domain/config/fmwconfig/jps-config.xml

Añadimos:

<propertySet name="trust.provider.embedded">
<property value="oracle.security.jps.internal.trust.provider.embedded.EmbeddedProviderImpl" name="trust.provider.className"/>
<property value="60" name="trust.clockSkew"/>
<property value="1800" name="trust.token.validityPeriod"/>
<property value="false" name="trust.token.includeCertificate"/>
<property value="orakey" name="trust.aliasName"/>
<property value="orakey" name="trust.issuerName"/>
</propertySet>

3.- Configuro el JKS a través de wlst.sh

/oracle/middleware/Oracle_WC1/common/bin/wlst.sh

connect('weblogic','Oracle11g','t3://owc1:7001')
updateCred(map="oracle.wsm.security", key="keystore-csf-key", user="owsm", password="welcome1", desc="Keystore key")

updateCred(map="oracle.wsm.security", key="enc-csf-key", user="orakey", password="welcome1", desc="Encryption key")

updateCred(map="oracle.wsm.security", key="sign-csf-key", user="orakey", password="welcome1", desc="Signing key")

disconnect()

exit()

4.- Reiniciamos los servidores

Reiniciamos todos los servidores manejados.

5.- Configuramos WLS Trust Service Asserter

1. Accedemos a la consola de WLS
2. Navegamos a Security Realms -> myrealm
3. Nuevo proveedor de autenticación
4. Nombre del "asserter" (por ejemplo, TrustServiceIdAsserter).
5. Seleccionamos TrustServiceIdentityAsserter como tipo.
6. Activar cambios

6.- Configuramos a través de WLST

/oracle/middleware/Oracle_WC1/common/bin/wlst.sh

connect('weblogic','Oracle11g','t3://owc1:7001')

createCred(map="o.webcenter.jf.csf.map", key="keygen.algorithm", user="keygen.algorithm", password="AES")

createCred(map="o.webcenter.jf.csf.map", key="cipher.transformation", user="cipher.transformation", password="AES/CBC/PKCS5Padding")

disconnect()
exit()

7.- Reiniciamos los servidores

Reiniciamos los nodos manejados

Por último, accedo a: http://owc1:8888/rest/api/resourceIndex y vemos el resultado obtenido

Performance of Fusion Middleware

I've just saw a great post from Daniel Mortimer grouping a recopilation of tunning and performance tips on FMW applications.

Installing Weblogic 10.3.6 in command line mode

A couple of days ago I was installing a WLS PS5 for a WebCenter Content installation. Im using linux 64bit version and found an annoying bug.

If you start the installation in GUI mode, the wizard will ask you for the oracle support mail and password. I tried several times to skip that step, but the installation does not allow any action to bypass it.

So my last chance, was the installation by command line, these are the steps of the complete process:
