This chapter describes issues associated with Oracle WebCenter. It includes the following topics:
This section describes general issues and workarounds. It includes the following topics:

Section 12.1.12, "Running Oracle WebCenter with Microsoft ActiveDirectory"
Oracle WebLogic Communications Server (OWLCS) is provided as a sample for development only. It should not be used for production deployments.
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.
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.
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.
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:
In the Application Navigator, click the Application Menu icon next to your application's name and select Application Properties.
In the Application Properties dialog, expand the Run node in the left pane, then select MDS.
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.
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.
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:
if "%WC_APPSDIR_ARGUMENT%"=="" {
set %WC_APPSDIR_ARGUMENT%=-Dwc.apps.dir=%WC_APPS_DIR%
set EXTRA_JAVA_PROPERTIES=%WC_APPSDIR_ARGUMENT% %EXTRA_JAVA_PROPERTIES%
}
Replace the entry with the entry given below. The exact changes that you need to make are marked in bold.
if "%WC_APPSDIR_ARGUMENT%"=="" {
set %WC_APPSDIR_ARGUMENT%=-Dwc.apps.dir=%WC_APPS_DIR%
set EXTRA_JAVA_PROPERTIES=-Dwc.apps.dir=%WC_APPS_DIR% %EXTRA_JAVA_PROPERTIES%
}
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.
To install Oracle Secure Enterprise Search (Oracle SES):
Install Oracle SES 10.1.8.2.
For information about how to install Oracle SES 10.1.8.2, refer to the Oracle Secure Enterprise Online Documentation Library 10g Release 1 (10.1.8.2) available here on OTN:
Install the Oracle SES 10.1.8.4.0 patch set.
To do this, download patch 7514463 from http://support.oracle.com.
Install the Oracle SES Oracle Database Connector 10.1.8.4.4 patch set.
To do this, download patch 9022819 from http://support.oracle.com.
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.
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) 10.1.3.4.0, 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:
Download patch 5912518 and 6690355 from http://support.oracle.com.
From your Oracle Secure Enterprise Search 10.1.8.4 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
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.
This section describes documentation errata. It includes the following topics:
In Oracle Fusion Middleware Developer's Guide for Oracle WebCenter, in the section "How to Create a Content Repository Connection Based on the Oracle Content Server Adapter", the description for the URL of the Web Server Plugin parameter in the table "Configuration Parameters for Oracle Content Server" reads:
"If the RIDC socket type is web, then the URL must be in this format: http://host_name/web_root/plugin_root. For example: http://mycontentserver/cms/idcplg"
This description should read as follows:
"If the RIDC socket type is web, then the URL must be:
For Oracle Content Server release 11.1.1.3.0: http://host_name:port_number/_dav/web_root/plugin_root. For example: http://mycontentserver:4444/_dav/cms/idcplg
For Oracle Content Server release 10.1.3.4.1 or 10.1.3.5: http://host_name:port_number/web_root/plugin_root. For example: http://mycontentserver:4444/cms/idcplg"
In Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter, in the section "Default Identity and Policy Stores", we describe the LDAPs supported for the policy store as:
"The policy store can only be configured to use Oracle Internet Directory 11gR1 and 10.1.4.3, and OVD 11gR1 with the Local Store Adapter (LSA)."
The description should read:
"The policy store can only be configured to use Oracle Internet Directory 11gR1 and 10.1.4.3."
Oracle WebCenter no longer supports OVD 11gR1 with the Local Store Adapter (LSA) for use with the policy store.
