Jboss throw ClassNotFoundException: XMLGregorianCalendarImpl

ngthphat Aug 10, 2012 11:58 AM

Hi all,

I developed a ear file with some webService inside.

This is a part of my DTO:

     public XMLGregorianCalendar getStartDate() {
                    if(startDate != null){
                              startDate.setTimezone(DatatypeConstants.FIELD_UNDEFINED);
                    }
                    return startDate;
          }


          /**
           * @param startDate the startDate to set
           */
          @XmlSchemaType(name = "date")
          public void setStartDate(XMLGregorianCalendar startDate) {
                    this.startDate = startDate;
          }

I use maven to build my ear file:

                              <plugin>
                                        <groupId>org.apache.maven.plugins</groupId>
                                        <artifactId>maven-compiler-plugin</artifactId>
                                        <version>2.3.2</version>
                                        <configuration>
                                                  <source>${jdkVersion}</source>
                                                  <target>${jdkVersion}</target>
                                        </configuration>
                              </plugin>


                              <plugin>
                                        <artifactId>maven-ejb-plugin</artifactId>
                                        <version>2.3</version>
                                        <configuration>
                                                  <ejbVersion>3.1</ejbVersion>
                                        </configuration>
                              </plugin>

Then, I deploy ear file to Jboss 7.1.1 and try to invoke to web service. However, jboss alway throw a exception, this is a part of log:

Caused by: java.lang.RuntimeException: ClassNotFoundException marshaling EJB parameters
          at org.jboss.as.ejb3.remote.LocalEjbReceiver.clone(LocalEjbReceiver.java:229) [jboss-as-ejb3-7.1.1.Final.jar:7.1.1.Final]

Does someone know why jboss throw that exception? And how to fix it?

I deployed to Glassfish 3.1 and my web service work correctly.

Do you package any xerces jar in your app? My guessing is GlassFish doesn't bundle in a xerces.jar whereas jboss does have a ./modules/org/apache/xerces/main/xercesImpl-2.9.1-jbossas-1.jar. So no conflict when deploying to GlassFish and everything just works. In JBoss, there could be some library conflict or shadowing between the server and the app.

In AS7 we do allow users to package their own versions of xerces. So that shouldn't be a problem in AS7.

Caused by: java.lang.ClassNotFoundException: org.apache.xerces.jaxp.datatype.XMLGregorianCalendarImpl from [Module "my.ear.file.xxx" from Service Module Loader]
So your application has a dependency on the XMLGregorianCalendarImpl. Have you packaged it as a jar within the application? If so, where is it located. Also post a bit more about your packaging details.

@Cheng Fang: I don't package nay xerces in my ear file. I checked xercesImpl-2.9.1-jbossas-1.jar, Jboss already had XMLGregorianCalendarImpl

"In JBoss, there could be some library conflict or shadowing between the server and the app"
=> I think so as well.

@jaikiran pai: Because of some reason, I need XMLGregorianCalendar in DTO part. This is content of my ear file.

my_ear-1.01.18-SNAPSHOT.ear lib -----> commons-collections-3.2.1.jar -----> commons-logging-1.1.1.jar -----> commons-lang-2.4.jar META-INF -----> application.xml activation-1.1.jar ejb-api-3.0.jar hibernate-validator-4.0.0.GA.jar jaxb-api-2.1.jar jaxb-impl-2.1.3.jar jsr250-api-1.0.jar slf4j-api-1.5.6.jar stax-api-1.0-2.jar validation-api-1.0.0.GA.jar xml-apis-ext-1.3.04.jar my_service-1.01.18-SNAPSHOT.jar

I use hibernate as persistence provider.

Every one of those jars in the root of your ear file, except the ones in the lib directory, slf4j-api.jar and my_service-1.01.18-SNAPSHOT.jar don't need to be there, because they contain classes provided by JBoss or the JDK. The slf4j-api.jar will be more useful in the lib directory too.

I fixed by add dependencies in manifest, and it works:

<configuration> <displayName>xcrm_ear</displayName> <includeInApplicationXml>true</includeInApplicationXml> <archive> <manifestEntries> <Dependencies>org.apache.xerces, org.dom4j</Dependencies> </manifestEntries> </archive> </configuration>

@Stephen Coy: Thanks for your idea, I will refactor my project.

Thank jaikiran pai and Cheng Fang as well

Very cool thx, this fixed my problem. However I got this error in combination with artemis-activemq and wildfly-10
