wsgen ClassCastException from JPrimitiveType to JClass
------------------------------------------------------
Key: XFIRE-806
URL: http://jira.codehaus.org/browse/XFIRE-806
Project: XFire
Issue Type: Bug
Components: Generator
Affects Versions: 1.2.3
Environment: Windows, Ant
Reporter: Geert Engels
Assigned To: Dan Diephouse
Using Ant wsgen task from xfire 1.2.3 against WSDL from
https://adwords.google.com/api/adwords/v8/CampaignService?wsdl I get:
[wsgen] 15-Dec-2006 09:20:04 org.codehaus.xfire.gen.Wsdl11Generator generate
[wsgen] INFO: Generating code for WSDL at
file:/c:/work/workspace/bcp/src/etc/wsdl/ggl/CampaignService.wsdl with a ba
e URI of file:/c:/work/workspace/bcp/src/etc/wsdl/ggl/CampaignService.wsdl
[wsgen] 15-Dec-2006 09:20:04
org.codehaus.xfire.gen.jsr181.AbstractServiceGenerator generate
[wsgen] INFO: Creating class com.teracode.bcp.api.ggl.CampaignInterface
BUILD FAILED
C:\work\workspace\bcp\build\build.xml:72:
org.codehaus.xfire.gen.GenerationException: Could not find holder type.
This seems to be the same as question posted on Nov 2nd here
http://www.mail-archive.com/[email protected]/msg01259.html to which
there never was a reply.
Running the Ant task through a debugger, I can intercept an embedded
ClassCastException, which originates at line
org.codehaus.xfire.gen.jsr181.AbstractServiceGenerator.java:252.
The code there is as follows:
protected JType getHolderType(GenerationContext context,MessagePartInfo part)
throws GenerationException
{
JType genericType = context.getSchemaGenerator().getType(context,
part.getName(), part.getSchemaType().getSchemaType());
try {
JClass holder = context.getCodeModel().ref("javax.xml.ws.Holder");
holder = holder.narrow((JClass) genericType); /* THIS IS WHERE THE
CLASSCASTEXCEPTION OCCURS */
return holder;
} catch (Exception e) {
throw new GenerationException("Could not find holder type.", e);
}
}
The MessagePartInfo, when the ClassCast is thrown, contains a schemaType which
stringifies to "org.codehaus.xfire.aegis.type.basic.ObjectType[class=<null>,
QName={https://adwords.google.com/api/adwords/v8}responseTime]";.
The ClassCastException is from JPrimitiveType to JClass.
Anybody know how to get Xfire wsgen to work with this WSDL? All others from
WSDLs from Google AdWords API, not only this service but all others, and not
only v8 but v7 and v6 as well, fail in the same way.
It's easy to reproduce, using a testcase as per below:
import junit.framework.TestCase;
public class WsGenTest extends TestCase {
public void testIt() throws Exception {
WsGenTask task = new WsGenTask();
task.setOutputDirectory("C:/EXT");
task.setWsdl("https://adwords.google.com/api/adwords/v8/CampaignService?wsdl";);
task.setPackage("blah");
task.setOverwrite(true);
task.setGenerateServerStubs(false);
//task.setCaseSensitive(false);
//task.setDefaultexcludes(false);
try {
task.execute();
} catch( Throwable t ) {
t.printStackTrace();
fail(t.toString());
}
}
}
