[jira] Created: (ODE-101) TransformerFactory is used without
initialization in Start()
TransformerFactory is used without initialization in Start()
------------------------------------------------------------
Key: ODE-101
URL: https://issues.apache.org/jira/browse/ODE-101
Project: Ode
Issue Type: Bug
Components: JBI Integration
Environment: Windows XP Pro, ServiceMix 3.1
Reporter: Xuli
Priority: Critical
After deployment of ODE engine, quit ServiceMix then restart it. Now, execute a process with doXslTransform will cause the problem.
While deploying the ODE engine, ServiceMix will invoke OdeServiceUnit.Deploy() method to instanciate a compiler according to the BPEL script version, then in turn instanciate a "XPath10ExpressionCompilerBPEL20" or "XPath20ExpressionCompilerBPEL20" object in which one's constructor, the TransformerFactory will be initiated by executing the following lines:
---------------------------------------------------------------------------------------------------------
TransformerFactory trsf = new net.sf.saxon.TransformerFactoryImpl();
XslTransformHandler.getInstance().setTransformerFactory(trsf);
---------------------------------------------------------------------------------------------------------
But after deployment, the ServiceMix will invoke init()->start() only. The TransformerFactory will keeping uninitialized and will cause the problem while executing DoXslTransformFunction.Function()->XslTransformHandler.getInstance().cacheXSLSheet(xslUri, xslSheet.sheetBody, resolver)->parseXSLSheet(uri, body, resolver)->_transformerFactory.setURIResolver(resolver)

--------------------------
Maybe add following lines to "org.apache.ode.bpel.elang.xpath10.runtime.XPath10ExpressionRuntime.initialize(Map properties)" is better to solve the problem:
public void initialize(Map properties) throws ConfigurationException {
--------------------------------------------------------------------------------------------------------------
TransformerFactory trsf = new net.sf.saxon.TransformerFactoryImpl();
XslTransformHandler.getInstance().setTransformerFactory(trsf);

------------------------------------
Ok, i get it, the problem is that if you only use Xpath 1.0 it won't get initialized properly (bc the init occurs in XPath20 module only).
Xuli last suggested fix seems the way to go. I'll check that in.

-----------------------------------
Yeah, I'm not sure I'm following either. We can't really resolve the problem by adding these lines where they don't necessarily belong to. Could you give us a stacktrace for the exception so we can check the problematic code path? Thanks.

------------------------------------
I'm not sure I follow. The lines you refer to get called in XPath20ExpressionRuntime.initialize, so I don't see why you'd be getting a problem, unless something else was going on. Can you provide an exception trace showing the error?

Xuli updated ODE-101:
---------------------
Affects Version/s: Incubator
I solved this problem by adding the following lines to org.apache.ode.jbi.OdeServiceUnit.Start():
if (_registered.size() != pids.size()) {
for (QName pid : new ArrayList<QName>(_registered))
try {
_ode._server.unregister(pid);
_registered.remove(pid);
} catch (Exception ex) {
__log.error("Unable to unload " + pid, ex);
}
}
else
{
-------------------------------------------------------------------------------------------------------
// Initialize _transformerFactory member of XslTransformHandler
TransformerFactory trsf = new net.sf.saxon.TransformerFactoryImpl();
XslTransformHandler.getInstance().setTransformerFactory(trsf);
