Method Detail

getXmlaTransform

public static String getXmlaTransform(String xmlaPrefix)

This is a parameterized XSLT. The parameters are: "soap" with values "none" or empty "content" with values "schemadata", "schema", "data" or empty With these setting one can extract from an XMLA SOAP message the soap wrapper plus body or simply the body; the complete body (schema and data), only the schema of the body, only the data of the body or none of the body

getCatalogLocator

public static CatalogLocator getCatalogLocator()

getDataSources

public static DataSourcesConfig.DataSources getDataSources(String connectString,
                                                           Map<String,String> catalogNameUrls)
                                                    throws org.eigenbase.xom.XOMException

Throws:

public static String getDataSourcesText(String connectString,
                                        Map<String,String> catalogNameUrls)

With a connection string, generate the DataSource xml. Since this is used by directly, same process, communicating with XMLA Mondrian, the fact that the URL contains "localhost" is not important.

Parameters:

connectString - Connect string

catalogNameUrls - array of catalog names, catalog url pairs

This validates a XMLA response using xpaths to extract the schema and data parts. In addition, it does a little surgery on the DOMs removing the schema nodes from the XMLA root node.

Throws:

SAXException

IOException

XPathException

validateNodes

Validate Nodes with throws an error if validation was attempted but failed, returns true if validation was successful and false if validation was not tried.

Returns:

true if validation succeeded, false if validation was not tried

Throws:

                                             TransformerException

A given Document has both content and an embedded schema (where the schema has a single root node and the content has a single root node - they are not interwoven). A single xsl transform is provided to extract the schema part of the Document and another xsl transform is provided to extract the content part and then the content is validated against the schema.

If the content is valid, then nothing happens, but if the content is not valid an execption is thrown (currently a RuntimeException).

When Mondrian moves to Java 5 or includes the JAXP 1.3 jar, then there is a utility in JAXP that does something like this (but allows for multiple schema/content parts).

Throws:

SAXException

IOException

ParserConfigurationException
