FAST ESP 5.3 - is the FAST Search API of ESP 5.3 compatable with OS: Red Hat 5.1 & JDK: 1.6 Update 81 ?

FAST ESP 5.3 - is the FAST Search API of ESP 5.3 compatable with OS: Red Hat 5.1 & JDK: 1.6 Update 81 ?

Per ESP SP 5 release , below OS are supported which should be compatible with API:
 Red Hat Enterprise Linux Release 5.8, 32-bit (and all 5.x minor versions below)
 Red Hat Enterprise Linux Release 5.8, 64-bit (and all 5.x minor versions below)
 Red Hat Enterprise Linux Release 6.3, 32-bit (and all 6.x minor versions below)
 Red Hat Enterprise Linux Release 6.3, 64-bit (and all 6.x minor versions below)
 SuSE Linux Enterprise Server 11, 64-bit
The latest JDK i have seen working on a customer install is jdk1.6.0_45.
Probably you can try update 81 and see if you run into any issues.

XPath API woes

I'm trying to parse an XML document using the Actionscript 2
XPath API. In one place I am using this as my xpath:
presentation/content[@contentName='wellness']/section[@sectionName='Nutrition/Weight']'
It fails when I use a slash in the "sectionName" attribute,
when I remove the slash in the XML file and change the xpath
accordingly it works fine. This XML is being generated for me, so I
really have no choice in the matter, the slash has to stay. Is
there something I can do to get around this problem?

<PName>Product NameX2</PName>
</Product>
</ProductList>
</DataVO>
</DataList>
</Data>
The Problem
=========
While I am maintaining the relationship parsing through XPath API , I am giving to fetch products as API path as "/Data/Datalist/DataVO/ProductList/Product/ProductId" to get the list of products, I can able to get the 4 Products NodeList, But I want to set the each products "VoId" , Like P101 related with 100, P102 related with 100, P201 related with 101, P202 related with 101. Any Sugesstions, parsing logics?

Namespaces are not evaluated as XML constructs in XPath, but namespaces are required to be configured in the parser. Refer

How to add Documents object faster(DI-API)

Hello,
I investigated the time concerning adding to Order Document using DI-API.
Result,339sec per 300 document(for each document has
4 items ,program was not use Start/End transaction).
This result is not so bad, but i wish faster time.
Please suggest faster way to add Documents object using
DI-API.
My source code is below.
vINV = vCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oOders)
For I = 1 To 300
vINV.CardCode = "test"
vINV.Docdate = "2005/12/31"
vINV.DocDueDate = "2005/12/31"
vINV.NumAtCard = "test"
   For J = 0 To 3
     vINV.Lines.ItemCode = "test"
     vINV.Lines.Quantity = 1
     vINV.Lines.Price = 400
     if J <> 3 Then
       vINV.Lines.add()
     End If
    Next J
   RetVal = vINV.Add
Next I

Hi Jiro,
I have never worked with this before, but maybe you can investigate using the DI Server. Search the forum for the DI Server. Herewith an extract from the DI Server help file:
<i>SAP Business One - Data Interface Server (DI Server) is a Component Object Model (COM) service running on a server that enables multiple clients to access and manipulate SAP Business One company database, using SOAP version 1.1 messages.
The DI Server uses the DI core to enable the same functionality provided by the DI API with the following advantages:
- Server architecture.
- <b>Improved performance.</b>
- Connection pooling mechanism.
- Generic interface.
The DI Server operates with SAP Business One application version 2004.</i>
Hope it helps,

I encountered the same problems with binding date variables on Solaris. The SQLBindParamater would be successful for the date, but during the SQLExecute I always get this error:
ORA-01483: invalid length for DATE or NUMBER bind variable
I logged an official service request, and Oracle confirmed the problem. You can see it at bug 5241003. FYI, there is currently no estimated time for a fix.

XPath for Java

Hi all,
I have an xml and i would like to do some query to the xml.
Is there any XPath API that i can use in java ?
Currently using 1.4.2
Is there any other recommendations?
Thanks

XPATH sample code

Hi ,
Does Oracle 9.2.0 has XPATH API's?
I need to use XPATH to extract data from an XML document.
I searched over the net but I am not able to find usage of Oracle XPATH API's in c/c++ .
Can anybody please provide me a code sample to use Oracle 9.2.0 XPAPTH API's.
Thanks

XPath Not Working (Namespace ?)

I am not receiving any errors, but similair XPath in XMLSpy works...
I have an XML document:
<Results>
<acc:Account xmlns:account="http://test/account" id="1">
<acc:Name>Account Name 1</acc:Name>
</acc:Account>
<acc:Account xmlns:account="http://test/account" id="2">
<acc:Name>Account Name 2</acc:Name>
</acc:Account>
</Results>
When I use: "//Results" I get a a Node back
When I use: //Results/acc:Account[@id=1], I get no results back and no errors
To avoid namespace problems I used a StaticNamespaceResolver...
My code:
HashMap prefixes = new HashMap(1);
String namespace = "http://test/account";
prefixes.put("acc", namespace);
try {
XObject obj = XPathAPI.eval(RootNode, queryStr, new StaticPrefixResolverImpl(prefixes));
NodeList nl = obj.nodelist();
System.out.println("NodeList Length: " + nl.getLength());
} catch (Exception ee) {
System.out.println(ee);
Thanks!

Seems to me your problem is that you can't decide what prefix to use...
Is it 'acc' or 'account' ?
In your sample document, try:
<Results>
<acc:Account xmlns:acc="http://test/account" id="1">
<acc:Name>Account Name 1</acc:Name>
</acc:Account>
<acc:Account xmlns:acc="http://test/account" id="2">
<acc:Name>Account Name 2</acc:Name>
</acc:Account>
</Results>And see what the difference is...
Also, the prefix you use in your XPath expression does not have to be the same as the one used in the document. They are linked via the URI and a NamespaceContext. It's quite likely you'll need to implement a NamespaceContext (depending on what XPath API you are using).

Fastest method to load external data?

Hi,
Currently we load external xml file and parse it for our
internal use.
However, parsing take time, is it possible to reduce this
step?
Such as serialize / de-serialize?
thanks.

Are you using Xpath API to parse your xml? This will help
some doing just queries but some parsing will still need to be
done.
Another solution is to not load xml but use Flash remoting.
Flash remoting is a binary format and much faster. WIth Flash
remoting you can pass all your items in the native formats defined
in PHP, ASP.Net, or ColdFusion.

Xml file not loading

i am trying to create an e-learning course that will have
glossaries according to the various lessons that are within the
overall course. i have attached the code that i am using to quickly
switch out the glossary xml file (that contains the definitiosn and
terms). I can currently trace the lessonNumber variable (it is
reading "1"), but when I attempt to trace the glossaryText
variable, the output window is blank....can anyone tell me where i
am going wrong?

Just a hint - perhaps try putting your onLoad declaration
BEFORE your load command. This way, your onload is present before
the load is issued, so in case the XML is loaded really quickly,
the onLoad handler will get called for sure. Does this make sense?
In your case, the XML may have already loaded before you tell the
object WHAT to call after it's loaded.
When I've used the xml object, it looks more like this:
myXML = new XML();
myXML.onLoad = someFunction;
myXml.load("somexmlfile.xml");
Also -afterwards, you have to select a node of the XML to
view. I use the XPath API to do so, by including this
import mx.xpath.XPathAPI;
And then using:
XPathAPI.selectSingleNode within an onLoad function. Take a
look at the documentation for XPathAPI - I had to make a custom
function to return the node I wanted.
Hope this helps you.

Reading a XML file in a standalone java application

Hi,
What are my options if I have a standalone java application running outside any app. server and I need to read an XML file, probably read some of the attributes in the file...? Please explain clearly as I'm new to this. Appreciate your help.
Thanks,
Mahdad

nope you don't need a DTD
you have to write your Java code in a way that doesn't rely too much on the structure:
- avoid getFirstChild().getFirstChild()... because you know that this element is first grandson of that element)
- prefer using getElementByTagName() or some XPath() API
but if the XML completely changes, well, yeah, you have to do some programmation: better think well your document structure in the beginning.

Urgent help for processing XML stream read from a JAR file

Hi, everyone,
Urgently need your help!
I am reading an XML config file from a jar file. It can print out the result well when I use the following code:
===============================================
InputStream is = getClass().getResourceAsStream("conf/config.xml");
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line;
while ((line = br.readLine()) != null) {
System.out.println(line); // It works fine here, which means that the inputstream is correct
// process the XML stream I read from above
NodeIterator ni = processXPath("//grid/gridinfo", is);
Below is the processXPath() function I have written:
public static NodeIterator processXPath(String xpath, InputStream byteStream) throws Exception {
// Set up a DOM tree to query.
InputSource in = new InputSource(byteStream);
DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance();
dfactory.setNamespaceAware(true);
Document doc = dfactory.newDocumentBuilder().parse(in);
// Use the simple XPath API to select a nodeIterator.
System.out.println("Querying DOM using " + xpath);
NodeIterator ni = XPathAPI.selectNodeIterator(doc, xpath);
return ni;
It gives me so much errors:

org.xml.sax.SAXParseException: The root element is required in a well-formed document.This often means that the parser can't find the document. You think it should be able to find the document because your test code could. However if your test code was not in the same package as your real (failing) code, your test is no good because getResourceAsStream("conf/config.xml") is looking for that file name relative to the package of the class that contains that line of code.
If your test code wasn't in any package, put a slash before the filename and see if that works.
