Enums don't match schema: problem with jaxb or xsd?

Question

I\'m trying to use JAXB to unmarshal this file into Java objects. I know that there\'s a problem with SAX in J6 that rejects the maxOccurs line, and I\'ve changed it to

Answer 1

There are a couple of enumeration values that are causing this issue. These issues can be overcome through the use of a JAXB external binding file (see below).

Enum Issue #1 - Empty String

Some of your enum values are empty string (""), which is causing a String rather than an enum property to be generated:

    
        Blank 
    

Enum Issue #2 - Numeric String

Some of the enum values are numbers which is causing a String rather than an enum property to be generated:

    
        6th grade 
   

Bindings File (bindings.xml)

The following bindings file can be used to address the issues with the educationLevelType, the concepts here can be applied to all the problematic types:

The XJC call can be made as follows (the -nv flag is described below):

xjc -nv -b bindings.xml -d out http://www.acf.hhs.gov/programs/cb/systems/nytd/nytd_data_file_format.xsd

This will cause the following Enum to be generated:

package gov.hhs.acf.nytd;

import javax.xml.bind.annotation.XmlEnum;
import javax.xml.bind.annotation.XmlEnumValue;
import javax.xml.bind.annotation.XmlType;

@XmlType(name = "educationLevelType")
@XmlEnum
public enum EducationLevelType {

    @XmlEnumValue("under 6")
    UNDER_6("under 6"),

    @XmlEnumValue("6")
    SIX("6"),

    @XmlEnumValue("7")
    SEVEN("7"),

    @XmlEnumValue("8")
    EIGHT("8"),

    @XmlEnumValue("9")
    NINE("9"),

    @XmlEnumValue("10")
    TEN("10"),

    @XmlEnumValue("11")
    ELEVEN("11"),

    @XmlEnumValue("12")
    TWELVE("12"),

    @XmlEnumValue("post secondary")
    POST_SECONDARY("post secondary"),

    @XmlEnumValue("college")
    COLLEGE("college"),
    @XmlEnumValue("")

    BLANK("");
    private final String value;

    EducationLevelType(String v) {
        value = v;
    }

    public String value() {
        return value;
    }

    public static EducationLevelType fromValue(String v) {
        for (EducationLevelType c: EducationLevelType.values()) {
            if (c.value.equals(v)) {
                return c;
            }
        }
        throw new IllegalArgumentException(v);
    }

}

maxOccurs Issue

For the maxOccurs issue, the following command line with the no verify (-nv) flag can be used to parse the XML schema:

xjc -nv -d out http://www.acf.hhs.gov/programs/cb/systems/nytd/nytd_data_file_format.xsd

This will get you past the following error without having to modify the XML schema:

parsing a schema... [ERROR] Current configuration of the parser doesn't allow a maxOccurs attribute value to be set greater than the value 5,000.
line 41 of http://www.acf.hhs.gov/programs/cb/systems/nytd/nytd_data_file_format.xsd

Failed to parse a schema.
