Solution/Workarounds:
-Place xmlparserv2.xml under bpel10.1.2.0.2/lib and put in bpel10.1.2.0.0/lib.

bpel.xml file

bpel.xml is the deployment descriptor. It has wsdl locations of all the web services the bpel process is invoking.

Also, other configurations may be set in this file (within tab).
Example:
1. Passing parameters from a jsp that invokes the bpel process.








]]>

2. Certain properties (like db prop) may be set in this file so that they dont need to be hardcoded in the bpel process itself. Click here for more information about setting properties in bpel.xml.

Reading properties from bpel.xml

You can define properties in bpel.xml file and then read these in the BPEL process using ora:getPreference("propname"). One of the adv being avoiding having any hard coded stuff in the bpel process.

Example - Define in bpel.xml
preferences
property name="sid"bpeldb/property
preferences

These may be read inside the bpel process:
String sidName= getPreference("sid");

BPEL Logging

Changes to the level of logging may be changed in the BPEL console >Manage BPEl Domains tab > Logging.

Logging level may be any one of the following:
--Debug
--Info
--Warn
--Error
--Fatal
--Off

Also, auditLevel (Under Configuration in Manage BPEL Domain) may also be set in the manage bpel domain to any of the following:
a. Off (no logging)
b. minimal (without any audit details)
c. production (all events logged, except assign activity)
d. development (all events logged, including assign activity)

Time out with Notification Service

There is an issue with the notification service. It times out quite often.
There is a patch available for that (that may be obtained from metalink) - 5014466. However this patch works with only the 10.1.2.0.0 version.
There is no backport of the fix to 10.1.2.0.2 as of now.

With 10.1.2.0.2 version, it gives the following error:
