I think I can answer your first question. From what I recall in
parsing/reading documents, InputStream is a poor choice for XML documents
that include other documents. An InputStream object can't tell you where
its source is. Therefore, there is no way to find relative paths. I would
try the following:

final URL schema1Url = BeanGenerator.class.getResource("xsd/schema1.xsd");
final XmlObject schema1 = XmlObject.Factory.parse(schema1Url);

See if that helps.

<br>
I have some xsd schemas in my source tree and I want to generate java<br>
sources with XML Beans.<br>
I cannot use ant or maven task, I have to do it in plain java.<br>
<br>
I use the following java code:<br>
<br>
final InputStream schema1Stream =3D<br>
BeanGenerator.class.getResourceAsStream(&quot;xsd/schema1.xsd&quot;);<br>
final XmlObject schema1 =3D XmlObject.Factory.parse(schema1Stream);<br>

final XmlObject schema2 =3D XmlObject.Factory.parse(schema2Stream);<br>
final XmlObject[] schemas =3D { schema1, schema2 };<br>
final BindingConfig config =3D new BindingConfig() {<br>
=A0 =A0@Override<br>
=A0 =A0public String lookupPackageForNamespace(String uri) {<br>
=A0 =A0 =A0return &quot;ch.mypackage&quot;;<br>
=A0 =A0}<br>
};<br>
<br>
final Filer filer =3D new FilerImpl(null, new File(&quot;.java/src/&quot;),=
 null,<br>

final XmlOptions options =3D new XmlOptions();<br>
options.setCompileDownloadUrls();<br>
XmlBeans.compileXmlBeans(null, null, schemas, config, null, filer,<br>
options);<br>
<br>
<br>
I have questions:<br>
<br>
1) The schemas have include statements like this:<br>
<br>
=A0 =A0&lt;xs:include schemaLocation=3D&quot;./th000008_extern.xsd&quot;/&g=
t;<br>
<br>
How can I make XmlBeans to include this schemas? Its located in the same<br=

folder as the original schema, but XMLBeans does not<br>
find it:<br>
<br>
URL &quot;./th000008_extern.xsd&quot; is not well-formed<br>
<br>
how to solve that?<br>
<br>
2) I want everything XmlBeans generates in the package &quot;ch.mypackage&q=
uot;.<br>
How can I to this? XmlBeans generates a lot of other stuff like xsb<br>
files which are not in that package.<br>
<br>
How can I say to XmlBeans to not generate this files?<br>
<br>
3) When I use one of the generated classes, there is the following<br>
runtime error:<br>
<br>
java.lang.RuntimeException: Cannot load SchemaTypeSystem. Unable to load<br=
