Using XPath from Java

I've heard that you can use XPath from within Java instead of having to use it within XSLT, but I'm not sure what the syntax is?
Does anyone know?
Thanks,
Oodi

import org.apache.xerces.parsers.DOMParser;
import org.apache.xpath.XPathAPI;
DOMParser parser = new DOMParser();
parser.parse(inputFile);
doc = parser.getDocument();
/* Search using XPATH */
String xpath = "/XpathToSearch";
NodeIterator nl = XPathAPI.selectNodeIterator(doc, xpath);
HTH,
Joe

Read xml using xpath in java

Hi ALL,
I have a xml as follows:
<AAA>
<BBB>
<CCC>xyz</CCC>
<DDD>abc</DDD>
</BBB>
</AAA>
Now using any of the java class, i just need read the value of "CCC" as follows:
(i.e using xpath i need to read the value)
String val = x.somemethod("/AAA/BBB/CCC");
Thanks!

In case you're curious - here's the dom4j equivalent of dvohra09's sample code.
SAXReader saxReader = new SAXReader("org.apache.xerces.parsers.SAXParser");
Document doc = saxReader.read(source); //Where source is your file, input source, input stream, reader, or url
String value = doc.valueOf("//AAA/BBB/CCC"); //Result given the xml from OP = 'xyz'OK - not much difference with this simple example but if you haven't settled on an API, dom4j is worth looking at (IMHO).

Using JNDI from Java Stored Procedures

Hi,
we want to call external services (mostly via middle tier/J2EE) from within the database (9i Rel. 2) using Java Stored Procedures and JNDI.
Does anybody have some hints/samples how to do this? Will we have to use oc4jclient.jar? If yes, how? Where can I find some more detailed documentation?
Lot's of questions...
Thank
Matthias

Uh, not JNI but JNDI you asked. And use of JNI should be generally discouraged unless there is absolutely no other way (like co-located CORBA code for decoupling+speed). Can you direct me to a HOW-TO Oracle DB JVM configuration page? I want to know how to configure the internal DB JVM in a hurry.
Thank you,
Bryan

Connecting to AW using AWConnection from java

Hi all,
I have some java code which performs some AW manipulation based on relational tables, the code works perfectly both inside the database and externally.
The problem I have is that I don't want to have to pass the username, password, and connectstring into the java procedure. I want to take advantage of the "kprb" type connection, i.e. I want to be able to use the defaultConnection method of the Oracle driver like I would with jdbc: the session has already been connected by sqlplus
I can't work work out if this is possible via the AWConnection method, I guess it must be using a loopback type connection based on the tnsnames.
Anyone know if it can be done?
Cheers,
Mark...

Hi Mark,
The AWXML api has a mode which does exactly what you want, you should create an Interaction object which contains a set of actions you want to perform. This object can then be serialized into xml by calling the writeToXML method on it. At this point, you can use the returned string to create a clob which is then passed to a pl/sql procedure called sys.interactionexecute. This procedure takes the xml as a clob and executes it in the internal jvm using the connection information from the envoker of the pl/sql procedure.

Using COM from java

hi all,
I'm trying to find a way to call functions from a C++ COM object (.tlb).
Since I don't have a clue about C++ I thought about using an API or Tool that will help me to generate the appropriate wrappers and stubs to use with java.
Does someone have any idea of an API or Tool which is suitable for the above scenario?
many thanks in advance..........

JNI : Unsatisfied Link Error using C++ from Java

Am using JNI to call a C Function which in turn creates a new C++ object and calls a method on it.
When I run the java program that calls this native method, I get a UnsatisfiedLinkError : No <lib> in java.library.path.
If I change the C function to do a simple printf instead of creating a new object , it works fine.
I am printng out the java.library.path before calling the loadLibrary method, the path is correct.
Am using Java 1.2.2 and compiling with gcc 2.7 on solaris 2.6 (Sun OS 5.6)
Any help would be appreciated. I have seen some other folks having similar problems but haven't seen any replies that seem to solve the problem.

The 'man' pages for ldd say this :
Using the -d or -r option with shared objects can give misleading results. ldd does a "worst case" analysis of the shared objects. However, in practice some or all of the symbols reported as unresolved can be resolved by the executable file referencing the shared object.
Most of them seem ok, but I am wondering about "__builtin_new", anyone know what shared lib that's supposed to be in ?

Using ByteBuffer from java.nio package

Hi,
I have a java.nio.ByteBuffer object that is returned from the C++ code, created using NewDirectByteBuffer. I would like to use this ByteBuffer object in my java code to create a WritableRaster object. I would like to avoid an array copy here as the data may be huge.
Could someone please let me know if there is a solution to this?
Thanks in advance for any help.

Warning: I know almost nothing about the java.awt.image package - so please take what Im going to suggest as the throw away, off the top of my head random rambling that it is......
Could you implement a custom DataBuffer which sits on top of a NIO ByteBuffer? Already, custom DataBuffers provide access for certain data types (e.g. theres a DataBufferByte, DataBufferDouble which wrap arrays) - so I guess you could write a NIODataBufferByte - or what ever - which sits on top of a ByteBuffer.
Im not sure how this would tie in with the SampleModel though (again, I dont know anything about this area).
Hopefully someone who knows this stuff will come across this thread and actually give you some decent advice :o)

Using Perl From Java!

Hi there, i have an assignment for university, part of it is to send data to a perl script through a Java applet. My perl script works, as i have tested it with a HTML form, however when i try it with java, i get nothing, nothing, no errors or warnings. Im using JBuilder6.
I am convinced that there is a problem with my code and a connection is not being opened, my lecturer cant see what the problem is (im not too impressed!) so i come to you.
All the perl does is create a file called test.txt and print within it the name, email..etc from the applet.
Thanks in Advance, Dave Williams.
JAVA:
void btnSendPosting_actionPerformed(ActionEvent e) { //Send Posting Event
name = txtName.getText();
email = txtEmail.getText();
message = txtareaText.getText();
path = txtFilePath.getText();
String url = "http://localhost/cgi-bin/diag.pl";
System.out.println("Url entered");
try
theURL = new URL(url);
System.out.println("Url prepaired");
catch (MalformedURLException f)
System.out.println("Bad URL: " + theURL);
try
System.out.println("Beggining Connection...");
URLConnection connection = theURL.openConnection();
connection.setDoOutput(true);
PrintWriter out = new PrintWriter(connection.getOutputStream());
out.print("txtName="+name +"&txtEmail="+ email +"&txtMessage="+ message +"&txtPath="+path);
out.close();
System.out.println("End of Connection");
catch (IOException f)
System.out.println("Error Opening Connection");
} //Send Posting Close bracket

Hi All heres the code with the propper tags i think, as for smorgasbords comment, I realise the security issue with java, but my lecturer seems to think its a good idea. Now the java applet opens a stream to my perl script and sends it parameters which the perl script uses to create the file. So java isnt making the file on any computer, perl is creating it on the server (EasyPHP actually). The example code given by my lecturer does actually work however for reasons which neither myself or the lecturer cannot see, it just doesnt create the file (or even open the perl script for that matter, as i used a file monitor to check if the 'diag.pl' file was accessed). I hope ive cleared up any questions.
Thanks
Dave

Hi,
You can try a package named: JTwain, which is available at http://asprise.com/product/jtwain.
JTwain supports all kinds of digital cameras and scanners. You can use Java to access, contorl digital cameras and scanners, and of course, to acquire images with flexible settings.
The developers' guide is available @ http://asprise.com/product/jtwain/devGuide.php
In the simplest case, one line of Java code can solve your problem.
Good luck!

Problem in using Timestamp from java.sql.*

AOA
i have declared a variable
private Timestamp entryDate = new Timestamp(8);while using it in my application. it inserts similar time stamp in database , like
01/01/1970 5:00:00 AM
How to get current time from it and how to insert it in databse.

AOA
i have declared a variable
private Timestamp entryDate = new Timestamp(8);
Why? What does that 8 mean to you? Did you read the docs to see what it means to Timestamp?
>

01/01/1970 5:00:00 AM
How to get current time from it and how to insert it
in databse.Did you read the docs for Timestamp? There's a constructor and/or a set method that takes a Date or a number of millis. You can get the current time in millis with System.currentTimeMillis. (I think that's the method name. Look at System's docs.)
As far as inserting it, you'll do something like this: TimeStamp ts = ...;
Connection con = DriverManager.getConection(...);
PreparedStatement ps = con.prepareStatement("insert into foo (bar) values (?)");
ps.setTimestamp(1, ts);
ps.executeUpdate(); Google for jdbc tutorial for more details.

Using DCs from Java DC

I need to use tc/wd/webdynpro (default) DC in a Java DC. I add it in Used DCs with Build Time (and I also try with build, design, run time...), compile and deploy successfull but when I run web dynpro DC that use Java DC (deployed with J2EE DC), the class IWDNodeNotificationListener is not found.
¿What option I need to use tc/wd/webdynpro DC in runtime?

Hi Sebastian,
I guess this is the problem with required class or package not defined. check this link once.

How to retrieve a node using xpath in java

Hi,
I need to make an application in which on click of a button an xml is
displayed on the browser.
Now when a user selects a node in the xml then i need the xpath of the selected node for some processing.
How to retrieve the xpath.
I am using Struts framework.

There is not a specific method for achieving this.
You can store the whole xml document into a defined
structure. And get the needed xpath by some index.Yes i know that i'll need to store the file.
But my XML is fixed and the same XML is used everytime.
Now the structure of the XML is like it has same named nodes inside the parent node.
example :
<Human>
<Person>
<Person></Person>
<Person>
<Person><name>fsfsdsdf</name></Person>
</Person>
</Person>
<Human>
Now if the user selects the person node which contains name node then how to get the XPATH.
Can u help regarding the same........

Using C# from java

Hi,
I need to integrate my java code with a C# system. There is a C# dll that I should use. What is the best way to do this?
Thanks,
Zohar.

There are some products to make working with JNI easier, for example JNIEasy (never used it myself, however).
You can also search Google for "java c# interoperability" or similar search terms.

Using XPATH to extract value.

I need some help to extract the LatestFillQuantity element value using XPATH.
in Java.
I am unable to extract the value of 10000.
Please help as to what have I done wrong.?
The Document configNode contains the flwg:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<i:Interest >
     <i:Generation>3</i:Generation>
     <i:Extension>
        <i:Active.From/>
        <i:Order>
          <i:Status>Confirm</i:Status>
          <i:LatestFillQuantity>100</i:LatestFillQuantity>
        </i:Order>
</i:Extension>
</i:Interest>
My Java Code
private void extractValue(Document configNode)
     XPathFactory factory = XPathFactory.newInstance();
        XPath xpath = factory.newXPath();
          try{
         XPathExpression expr
          = xpath.compile("//i:Order/i:LatestFillQuantity/text()");
         Object result = expr.evaluate(configNode, XPathConstants.NODESET);
         NodeList nodes = (NodeList) result;
         for (int i = 0; i < nodes.getLength(); i++) {
             System.out.println(nodes.item(i).getNodeValue());
         }catch(Exception e){
              System.out.println("Sorry,this aint working");
     }

The nodes being parsed are namespace prefixed.
To parse a namespace node with the JDK 5.0 javax.xml.xpath package, set the NamespaceContext on the XPath object.
An implementation of NamespaceContext with a single prefix corresponding to a namespace uri:
public class NamespaceContextImpl implements NamespaceContext{
public String uri;
public String prefix;
public NamespaceContextImpl(){}
public NamespaceContextImpl(String prefix, String uri){
     this.uri=uri;
     this.prefix=prefix;
public String getNamespaceURI(String prefix){
   return uri;
public void setNamespaceURI(String uri){
   this.uri=uri;
public String getPrefix(String uri){
   return prefix;
public void setPrefix(String prefix){
   this.prefix=prefix;
public Iterator getPrefixes(String uri){return null;}
}
