setDefaultValidateDTDs

public static void setDefaultValidateDTDs(boolean validate)

getMetaData

public ApplicationMetaData getMetaData()

setClassLoader

public void setClassLoader(java.lang.ClassLoader cl)

Set the class loader

Parameters:

ClassLoader - cl - class loader

getClassLoader

public java.lang.ClassLoader getClassLoader()

Gets the class loader

Returns:

ClassLoader - the class loader

getValidateDTDs

public boolean getValidateDTDs()

Get the flag indicating that ejb-jar.dtd, jboss.dtd & jboss-web.dtd conforming documents should be validated against the DTD.

setValidateDTDs

public void setValidateDTDs(boolean validate)

Set the flag indicating that ejb-jar.dtd, jboss.dtd & jboss-web.dtd conforming documents should be validated against the DTD.

load

public ApplicationMetaData load()
                         throws java.lang.Exception

load() This method creates the ApplicationMetaData. The configuration files are found in the classLoader. The default jboss.xml and jaws.xml files are always read first, then we override the defaults if the user provides them

getDocument

public static org.w3c.dom.Document getDocument(java.net.URL url)
                                        throws DeploymentException

Invokes getDocument(url, defaultValidateDTDs)

getDocument

public static org.w3c.dom.Document getDocument(java.net.URL url,
                                               boolean validateDTDs)
                                        throws DeploymentException

Get the xml file from the URL and parse it into a Document object. Calls new XmlFileLoader(validateDTDs).getDocumentFromURL(url);

Parameters:

url, - the URL from which the xml doc is to be obtained.

Returns:

Document

getDocumentFromURL

public org.w3c.dom.Document getDocumentFromURL(java.net.URL url)
                                        throws DeploymentException

Get the xml file from the URL and parse it into a Document object. Calls getDocument(url.openStream(), url.getPath());

Parameters:

url, - the URL from which the xml doc is to be obtained.

Returns:

Document

getDocument

public org.w3c.dom.Document getDocument(java.io.InputStream is,
                                        java.lang.String inPath)
                                 throws DeploymentException

Parses the xml document in is and created the DOM Document. DTD validation is enabled if validateDTDs is true and we install an EntityResolver and ErrorHandler to resolve J2EE DTDs and handle errors.

Parameters:

is, - the InputStream container the xml descriptor to parse

inPath, - the path information for the xml doc. This is used for only for error reporting.
