We have created a custom xpath function for use with SOA Suite and BPM. This has been built as per specified within the http://docs.oracle.com/cd/E29597_01/dev.1111/e10224/bp_appx_functs.htm#SOASE11100. We have also reviewed the Oracle Sample for mapper-107-ExtensionFunctions (sample demonstrates the use of user-defined extension functions). This has been registered with jDeveloper and SOA within the oracle.soa.ext_11.1.1 (run ant to include in oracle.soa.ext.jar)
We ideally want to use this is BPM within an xsl. However when consuming this function is either BPEL or BPM using an xsl, the xsl fails with an error such as:
XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is ora:doXSLTransformForDoc("xsl/Transformation_1.xsl", $inputVariable.payload). The XPath expression failed to execute; the reason was: javax.xml.transform.TransformerException: oramds:/deployed-composites/default/gwCustomXpathUtil_rev1.0/xsl/Transformation_1.xsl<Line 9, Column 113>: XML-22043: (Error) Extension function error: Method not found 'getWeekDayDate'. Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
In an Assign it operates fine and returns the expected result. We have included a combination of both of the Config files (ext-mapper-xpath-functions-config.xml and ext-soa-xpath-functions-config.xml) in the META-INF folder, however neither allow the use of this function in the XSL.
I believe there may be an issue getting the custom xpath functions within XSL files. Hence I have also raised an SR. Has anyone experiences of this?
Our SOA / BPM suite environment is using 188.8.131.52.4 and has the following patches applied:
