Regarding my question on how to parse out a value from an XML string: The
following is the method I use to create the string:
To create my XML String, I call the following method from a JSP.
The method passes a stored procedure from an Oracle database to an EJB that
actually generates the XML.
I return the XML String to the JSP.
public String getPlatformServerClusterDash(){
try {
String xml_string = "";
xml_string += "<PLATFORM__CLUSTER_SERVER_DASHBOARD>";
// Get the Context for the Query EJB
Context ctx = getContext(url, user, password);
ssga.QueryBeanHome home = (ssga.QueryBeanHome) ctx.lookup
("QueryBean");
// call the stored procedure for the QueryBean EJB to extract the
XML from database.
ssga.QueryBean the_ejb = home.create("EXECUTE
inventory.get_cluster_id_for_server( ?, " + PLATFORM_ID + " )");
xml_string += "\n<PLATFORM_GET_CLUSTER_ID_FOR_SERVER>";
xml_string += the_ejb.getXML();
xml_string += "\n</PLATFORM_GET_CLUSTER_ID_FOR_SERVER>";
xml_string += "</PLATFORM__CLUSTER_SERVER_DASHBOARD>";
// release the memory
the_ejb.remove();
// return the raw XML string
return xml_string;
}
catch (Exception e) {
e.printStackTrace();
return "Error: PlatformServerClusterDash";
}
}
