Error Creating Instance for target process BPM11g

Hi,

When you deploy your BPM process which has a initiator task and try to instantiate the process from BPM workspace, You might get this error   “Error Creating Instance for target process”

Cause :  There might be some business object hanging, means You might have created a business object  but haven’t used in any of the human task, then you get this error

Solution : Delete the business object if it is not required or use the business object as an input to any of the human task.

Cheers,

dvm:lookupValue() issue in BPM 11.1.1.5 ,11.1.1.6

It is a annoying issue that DVM lookup function (dvm:lookupValue()) used inside xsl transformation of a BPM doesn't work.

Solution:  Use a script task and fetch the desired value from DVM look up inside a BPM process.

Resolution:

  

1)      1) Check the JDK Requirement of the JDeveloper version which is to be installed. Eg. As per Oracle documentation for Jdev 11.1.1.6.0 the JDK shall be JDK_6.0_27 or above.

2)       2) Check the server jdk version.To do the same t go to location WL_HOME/common/bin/commEnv.cmd ad Look for lines like the ones below (examples are from a WLS install on a Unix machine)

#JAVA_USE_64BIT, true if JVM uses 64 bit operations.

3)      3) Install JDK version which is either server version or lower than that version and then build/migrate your service.
