12 Oracle WebCenter

This chapter describes issues associated with Oracle WebCenter. It includes the following topic:

12.1 General Issues and Workarounds

This section describes general issues and workarounds. It includes the following topics:

12.1.1 Using Oracle WebLogic Communications Server

Oracle WebLogic Communications Server (OWLCS) is provided as a sample for development only. It should not be used for production deployments.

12.1.2 Using Jive Forums Documentation

Oracle WebCenter Discussions (Jive Forums) is an optional component of Oracle WebCenter. Complete documentation for Jive Forums is included for reference. However, Jive software installations and upgrades outside of the WebCenter product installation are not supported.

12.1.3 Using the Rich Text Portlet

At runtime, if you encounter a null pointer exception while trying to customize or refresh the content of a Rich Text Portlet, reload the page, and then customize or refresh your portlet.

12.1.4 Expanding/Collapsing Folders in the All Saved Searches Task Flow (Accessibility Issue)

When using only the keyboard in WebCenter Spaces, you cannot expand or collapse folders in the All Saved Searches task flow. To work around this issue, view the saved searches using the Search main view task flow for personal saved searches, or the Search group main view task flow for group space-specific saved searches.

12.1.5 Clearing Customizations Stored in MDS

In Oracle JDeveloper, choosing Clean Runtime MDS Customizations from the Application menu does not clear the customizations made at runtime that are stored in the MetaData Services (MDS). You can delete customizations by either manually deleting them from the configured directory or by using JDeveloper.

To clear these customizations by using JDeveloper:

  1. In the Application Navigator, click the Application Menu icon next to your application's name and select Application Properties.

  2. In the Application Properties dialog, expand the Run node in the left pane, then select MDS.

  3. In the right pane, under Run: MDS, select Delete customizations before each run. Doing so clears the MDS of any runtime customizations every time you run the application. To save the runtime customizations every time you run the application, select Preserve customizations across application runs.

12.1.6 Removing Blank Spaces from DOMAIN_HOME and JDEV_SYSTEM_DIRECTORY Path Names

On a Windows platform, a WebCenter domain name cannot contain spaces, and the domain cannot be created in a folder that has a space in its path. Also, pages in custom WebCenter applications are not rendered if there is a space in the path to the system directory in Oracle JDeveloper. Therefore, ensure that DOMAIN_HOME and JDEV_SYSTEM_DIRECTORY paths do not contain spaces.

12.1.7 Configuring setDomainEnv.cmd for Using Wiki and Blog Services

On Windows platforms, if you want to use the Wiki and Blog services in Oracle WebCenter, you must modify the DOMAIN_HOME/bin/setDomainEnv.cmd.

Search for the following entry in the setDomainEnv.cmd file:

set %WC_APPSDIR_ARGUMENT%=-Dwc.apps.dir=%WC_APPS_DIR% 

Replace the entry with the entry given below. The exact changes that you need to make are marked in bold.

set %WC_APPSDIR_ARGUMENT%=-Dwc.apps.dir=%WC_APPS_DIR% 

12.1.8 Navigating in the Documents Tab in Internet Explorer 7 (Accessibility Issue)

When using only the keyboard in WebCenter Spaces in Internet Explorer 7, cursor position is not highlighted for certain buttons in the Documents tab and the Document List Viewer task flow in page edit mode. Although the cursor position indicator is not shown, the cursor focus for the button objects is correct. To work around this issue, use Internet Explorer 8 or any other supported browser like Safari 4.x or Firefox 3.x.

12.1.9 Installing Oracle SES

To install Oracle Secure Enterprise Search (Oracle SES):

  1. Install Oracle SES

    For information about how to install Oracle SES, refer to the Oracle Secure Enterprise Online Documentation Library 10g Release 1 ( available here on OTN:


  2. Install the Oracle SES patch set.

    To do this, download patch 7514463 from http://support.oracle.com.

  3. Install the Oracle SES Oracle Database Connector patch set.

    To do this, download patch 9022819 from http://support.oracle.com.

12.1.10 Setting Up IMP Connections to Microsoft OCS

When setting up an Instant Messaging and Presence (IMP) connection to Microsoft Office Communications Server (OCS), the connection wizard only shows the base.connection.url and domain parameters as mandatory. However, the userDomain and ocsServer parameters also are mandatory.

12.1.11 Crawling WebCenter Spaces with SES over an HTTPS Connection

If you configure Oracle Secure Enterprise Search (SES) to crawl WebCenter Spaces over an HTTPS connection using BASIC authentication, you must apply patch 6690355 to the SES home. Patch 6690355 is for Oracle Containers for J2EE (OC4J), which is a standalone installation of OC4J within the SES home. As indicated in the README file for patch 6690355, if you have not also installed patch 5912518, you must apply it first before applying patch 6690355.

To apply both patches:

  1. Download patch 5912518 and 6690355 from http://support.oracle.com.

  2. From your Oracle Secure Enterprise Search home, navigate to $ORACLE_HOME and run the following commands:

    bin/searchctl stop
    cd oc4j 
    setenv ORACLE_HOME <current-working-directory> 
    unzip p5912518_111000_GENERIC.zip
    unzip p6690355_101340_GENERIC.zip
    cd 6690355
    $ORACLE_HOME/OPatch/opatch apply -jdk ../../jdk -jre ../../jdk/jre
    cd .. 
    setenv ORACLE_HOME <current-working-directory>
    bin/searchctl start

12.1.12 Running Oracle WebCenter with Microsoft ActiveDirectory

When running Oracle WebCenter with a Microsoft ActiveDirectory identity store, ClassCastExceptions may arise. To work around this issue, you must apply patch 9039508. You can download the patch from http://support.oracle.com.
