Hi
I'm trying to add the ability to read an XML file into my WebObjects
application and I'm stumbling at the first hurdle. I wonder if anyone
can tell if I'm doing the right thing.
My application needs to read an XML file that has been exported from
FileMaker. The first few line of the file are:
<?xml version="1.0" encoding="UTF-8" ?>
<FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult";>
<ERRORCODE>0</ERRORCODE>
<PRODUCT BUILD="11/13/2002" NAME="FileMaker Pro" VERSION="6.0v4"/>
<DATABASE DATEFORMAT="d/M/yyyy" LAYOUT="" NAME="04_inquiriesfp5"
RECORDS="1" TIMEFORMAT="k:mm:ss "/>
<METADATA>
<FIELD EMPTYOK="YES" MAXREPEAT="1" NAME="accommodation" TYPE="TEXT"/>
<FIELD EMPTYOK="YES" MAXREPEAT="1" NAME="Action_ID" TYPE="NUMBER"/>
and so on ......
I have copied some code from Apple's XML Serialization documentation,
but the application fails while trying to read the above data file.
The exception message reads:
java.io.StreamCorruptedException: Caught EOFException while reading the
stream header
at
java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:840)
at java.io.ObjectInputStream.<init>(ObjectInputStream.java:163)
at
com.webobjects.foundation.xml.NSXMLInputStream.<init>(NSXMLInputStream.j
ava:290)
at Import.deserialize(Import.java:118)
"Import" is the name of my WOComponent. The message appears to say
that it struck End Of File while reading the header. What's wrong with
the header? Does this mean that the NSXMLInputStream class cannot cope
with an XML file produced by FileMaker? The documentation refers to
"transformation" of XML. Is it saying that XML files produced by third
parties (FileMaker), need to be reformatted before they can be read by
NSXMLInputStream?
Here is the code I copied:
import java.util.*;
import java.io.*;
import com.webobjects.appserver.xml.WOXMLDecoder;
import com.webobjects.foundation.xml.NSXMLInputStream;
public void deserialize() {
// Filename of the input file.
String filename = "/Library/WebObjects/enquiries.xml";
try {
// Create a stream from the input file.
FileInputStream input_stream = new
FileInputStream(filename);
// Create an XML-input stream.
NSXMLInputStream xml_stream = new
NSXMLInputStream(input_stream); <------- fails on this line
// Read the data.
String theString = (String)xml_stream.readObject();
int theInt = xml_stream.readInt();
// Close the streams.
xml_stream.close();
input_stream.close();
}
catch (IOException e) {
e.printStackTrace();
}
catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
