Unable to compile the JAXB generated java files

Question

Hi
I am using JAXB 2.0 API for binding process.
I have products.xml file as
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE PRODUCTDATA SYSTEM "products.dtd">
<PRODUCTDATA>
<PRODUCT PRODID="P001" CATEGORY="Books">
<PRODUCTNAME>Gone with the wind</PRODUCTNAME>
<DESCRIPTION>This is abt American Civil War</DESCRIPTION>
<PRICE>25.00</PRICE>
<QUANTITY>3</QUANTITY>
</PRODUCT>
</PRODUCTDATA>
and products.xsd(Schema file) as
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="PRODUCTDATA" type="prdt"/>
<xsd:complexType name="prdt">
<xsd:sequence>
<xsd:element name="PRODUCT" type="prd" maxOccurs="unbounded" />
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="prd">
<xsd:sequence>
<xsd:element name="PRODUCTNAME" type="xsd:string"/>
<xsd:element name="DESCRIPTION" type="xsd:string"/>
<xsd:element name="PRICE" type="xsd:positiveInteger"/>
<xsd:element name="QUANTITY" type="xsd:nonNegativeInteger"/>
</xsd:sequence>
<xsd:attribute name="PRODID" type="pid" use="required"/>
<xsd:attribute name="CATEGORY" type="xsd:string" use="optional"/>
</xsd:complexType>
<xsd:simpleType name="pid">
<xsd:restriction base="xsd:string">
<xsd:pattern value="[p]{1}/d{3}"/>
<xsd:length value="4"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
I am converting these schema file to java files by using binding compiler xjc.
So that three java files are genearated automatically.

Next step is to compile these three files
So I am compiling these three files it gives me compiler error as:

25 errors
I want all three files to compiled successfully.If it is compiled only then I will continue on Unmarshalling process

Answer 1

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)
HTH,
