perf issue when converting from java to edi

Hi Claude,

I have a perf issue when calling the smooks.filterSource() method.

This is my code:

StringSink sink = new StringSink();

ExecutionContext executionContext = smooks.createExecutionContext();

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

XStream xstream = new XStream(new DomDriver());

xstream.autodetectAnnotations(true);

xstream.toXML(ediResponse1G, byteArrayOutputStream);

Source source = new ByteSource(byteArrayOutputStream.toByteArray());

smooks.filterSource(executionContext, source, sink);

If I run only a request, the conversion from java object (ediResponse1G) to edifact works fine…but if I run 10 parallel threads I got this error:

As I said, the javaObject contains all the required fields, because the conversion has been made successfully with one single request.

Could you please help me to understand what the error cause is and why I got :

Caused by: java.lang.ClassNotFoundException: org.mvel2.compiler.Accessor

Considering that :

<version>2.5.2.Final</version>

is included in my application because the dependency has been resolved by smooks-core: 2.2.0 that is inside smooks-javabean-cartridge: 2.0.2?

Thanks in advance,

Serena

Hi Serena,

Posts need to be directed to the community since, while it's true I'm a core committer, I'm just one of many contributors.

About the error, looks like it's related to https://github.com/mvel/mvel/issues/194 . Can you create an issue in the relevant cartridge? One workaround to solving this could be synchronising the first execution.

Claude

Hi Claude,

sure, I'm going to open the issue.

Thanks,
