I'm trying out a java-based conversion of EDIFACT messages to XML. The conversion libraries give three different exceptions;
On the first one or two calls, I sometimes, but not always, can't unlock the api, because I'm on a one week trial license, and on a computer that is not directly connected to the internet:
<log>
2007-01-17 11:19:42,297 [EDIFACT_OUT] DEBUG no.nmd.was.messagecentral.map.AbstractMap - The call to StylusFileFactory.unlockAPI() failed:
2007-01-17 11:19:42,297 [EDIFACT_OUT] DEBUG no.nmd.was.messagecentral.map.AbstractMap - You must be connected to the internet to use an evaluation copy of Stylus Studio.
2007-01-17 11:19:42,312 [EDIFACT_OUT] DEBUG no.nmd.was.messagecentral.map.AbstractMap - The call to StylusFileFactory.unlockAPI() failed:

</log>
Then when I call the Converter for the second or third time after startup, I get one of the two following exceptions; either a NullPointerException or an InvalidFormatException. These two take turns, without any apparent pattern:
<NullPointer>

The EDIFACT.jar file is explicitly added to the classpath.
I run StylusStudio 2007 Enterprise suite, build 735f. I downloaded it for evaluation / proof-of-concept on Friday, so I'm on a one week evaluation license.
The code I'm developing runs on an IBM WebSphere app server, version 6.0.2.15, and the app server uses IBM java version 1.4.2. It runs on a Windows 2000 Workstation.
com.stylusstudio.bindir is C:\Programfiler\Stylus Studio 2007 XML Enterprise Suite\bin
I am trying to invoke the EDI adapter, in order to map an edifact string to XML (and then transform it to our generic message format). The Java code is a work in progress, and as of now it looks like this:
<javacode>
private static ConverterFactory factory = null;
public AbstractMap() {
super();
if (factory == null) {
if (StylusFileFactory.unlockAPI("XXX") != true) {
String eMsg = StylusFileFactory.getUnlockAPIError();
if (eMsg != null && eMsg.startsWith("Insert your")) {
logger.debug("Edit this demo program and insert your Installation ID in the call to unlockAPI");
logger.debug("Make sure CustomFileSystem.jar is in your classpath,");
logger.debug("then compile and run it again.");
}
else {
logger.debug("The call to StylusFileFactory.unlockAPI() failed:\n");
if (eMsg==null)
logger.debug("No reason for failure was returned.");
else logger.debug(eMsg);
}
}
else {
logger.debug("StylusFileFactory was unlocked ok.");
factory = ConverterFactory.newInstance();
System.setProperty("com.stylusstudio.bindir",
"C:\\Programfiler\\Stylus Studio 2007 XML Enterprise Suite\\bin");
}
}
}
protected GenericMessage Map(String messageString) {
String prop = System.getProperty("com.stylusstudio.bindir");
logger.debug("com.stylusstudio.bindir = " + prop);
try {
StringWriter sw = new StringWriter();
StreamSource input = new StreamSource(new ByteArrayInputStream(messageString.getBytes()));
StreamResult output = new StreamResult(sw);
Converter conv = factory.newConvertToXML("adapter:EDI:decode=no:tbl=no:typ=no:opt=yes");
conv.convert(input, output);
logger.debug(sw.toString());
}
catch (ConverterException ex) {
logger.error("Converter error: ", ex);
}
return null;
}
</javacode>
