oracle.jsp.parse.JavaCodeException - Root cause and solution

Sometimes we see the following exception after doing a webcenter portal deployment

Error details

OracleJSP error: oracle.jsp.parse.JavaCodeException: Line # 13, oracle.jsp.parse.JspParseTagScriptlet@5cefd96
Error: Java code in jsp source files is not allowed in ojsp.next mode.

Solution

Make sure that the web.xml in the Deployer project is empty, it should not have any adf library references.

It should looks as below.

<?xml version = '1.0' encoding = 'windows-1252'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">
</web-app>

Do we need to restart the managed server after webcenter deployments?

Yes, we need to restart the managed server after Webcenter deployments

Many developers are wondered why the changes made to the Webcenter are not dynamically obtain the changes?

An excerpt from the Webcenter portal documentation is as below

Most WebCenter application configuration changes that you make, through Fusion Middleware Control or using WLST, are not dynamic; you must restart the managed server on which the application is deployed for your changes to take effect. For example, when you add or modify connection details for WebCenter services such as Announcements, Discussions, Documents, Mail, and so on, you must restart the application's managed server.

There are several exceptions; portlet producer and external application registration is dynamic. Any new portlet producers and external applications that you register are immediately available in your WebCenter application and any changes that you make to existing connections take effect immediately too.

Fix for Oracle 12c database installation error: File not found C:\app\oracle12c\product\12.1.0\dbhome_2\ctx\admin\dr0ulib.sql.sbs

Sometimes we see the below error on installation of the Oracle 12c Database

File not found C:\app\oracle12c\product\12.1.0\dbhome_2\ctx\admin\dr0ulib.sql.sbs

Solution for the issue

1. Unzip the database zip files into one single directory (C:\DBSetup) say as below

• winx64_12102_database_1of2
• winx64_12102_database_2of2

2. Now copy the setup folder in 2nd folder to first older (If the windows asks for merging, do it)

3. Then abort the current installation and start fresh again. It should be done.

Code to read the adfc-config.xml parameters from managed bean in ADF

The sample code to  read the adfc-config.xml parameters from managed bean in ADF is as follows

# Get the adf context object and get the config object from there
ADFContext adfContext = ADFContext.getCurrent();
ADFConfig adfConfig = adfContext.getADFConfig();

# Read the details of adfc-config.xml in the form of a MAP
Map configurationMap = adfConfig.getConfigObject("http://xmlns.oracle.com/adfm/config");
Long rowLimit =(Long)configurationMap.get("jbo.row.limit");  

ADF JavaScript Partitioning for better performance

What is JS Partitioning?
By default ADF framework downloads a bunch of Java Script libraries on each page load and we should consider to bucket the JS library calls to reduce the number of calls made. By default all ADF pages need the boot.js and core.js files to operate.

Additionally, JS files are downloaded either combined as partitions or one for each component (if no partition is defined).

Why should we implement it?
ADF is smart enough to download only the javaScripts belonging to the components rendered on the page. If individual JS files are downloaded, however, then there will be lot of network traffic per page, slowing down the page performance. The solution is to use JavaScript Partitions.

How to implement it?
The exact procedure is to create the java script partitions xml file with the name adf-js-partitions.xml file in WEB-INF and configure the partitions as needed. More documentation can be found here

Change the Oracle SOA BPEL properties at runtime

Often it is useful to be able to set properties influencing behavior of a BPEL process after it has been deployed. Of course, a danger with changing settings at runtime is that they also need to be applied to the development branch in order to avoid the changes to be overwritten at redeployment of a process. Oracle provides several mechanisms of changing settings of a BPEL process at runtime.
