Using FOP and JBOSS EAP 7
When using JBOSS EAP 7 and Apache FOP, I randomly (?) get an exception when instantiating a new Fop object. When restarted, the code might work. I suspect a classload issue.
In a standalone situation (Eclipse) everything works fine. Some people suggest the FOP implementation is already loaded in a different security context. Beats me what that means.
Here is the Exception :
Caused by: java.lang.ClassCastException: org.apache.fop.render.afp.extensions.AFPExtensionHandlerFactory cannot be cast to org.apache.fop.util.ContentHandlerFactory
Sample code :
import java.io.File;
import javax.annotation.PostConstruct;
import javax.ejb.ConcurrencyManagement;
import javax.ejb.ConcurrencyManagementType;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import org.apache.commons.io.output.NullOutputStream;
import org.apache.fop.apps.FOUserAgent;
import org.apache.fop.apps.Fop;
import org.apache.fop.apps.FopFactory;
import org.apache.fop.apps.MimeConstants;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
/**
* Force classloader to use FOP apache implementations first (experimental)
*/
@Singleton
@Startup
@ConcurrencyManagement(ConcurrencyManagementType.BEAN)
public class InitBean {
private static final Logger logger = LogManager.getLogger(InitBean.class.getName());
public InitBean() {
super();
}
@PostConstruct
public void initClassloader() {
try {
FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, new NullOutputStream());
logger.debug("Created FOP handler {}", fop.getDefaultHandler().getClass().getName());
}
catch (Exception e) {
logger.error(e.getMessage());
}
}
}
Libraries : Apache fop 2.2; xalan-2.7.2; docx4j-export-fo-6.0.1; xmlgraphics-commons-2.2; xercesImpl-2.11.0; docx4j-6.0.1; serializer-2.7.2
How can I fix this issue?
