Hi Greg,
It was my mistake and a very basic java question. But you need not be rude for that.

Hi Thomas,
Thanks a lot for the help.
I am also facing problem in uploading my modified working memory back to my output file.
Once the rules are fired and the data in my working memory is modified how do I reupload it to my text file?
I store all my data in a vector which loads it to the working memory.
Could you point me towards some documentation which explains it?
Thanks so much.

Hi Greg,
I have my input files inside the src directory of my eclipse project.
I am passing the files as follows:
private static final String DATA_INPUT_FILE = new String []{ "Input1.txt", "Input2.txt"};
private static final String DATA_OUTPUT_FILE = "Output.1.txt";
private static final String RULES_FILES = new String [] {"Rule1.drl", "Rules2.drl"};
public static void main(String[] args) throws Exception {
BufferedReader input = new BufferedReader(new FileReader(DATA_INPUT_FILE));
Converter c = new Converter(DATA_INPUT_FILE); // this reads my input files
Vector<Object> v = new Vector<Object>();
v = c.getFactInput(); // loads all information contained in the input files
new RuleRunner().runStatelessRules(RULES_FILES,null, v,null); FileOutputStream output = new FileOutputStream(DATA_OUTPUT_FILE);
Error Log:
Exception in thread "main" java.io.FileNotFoundException: Input1.txt (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
at com.org.RulesTest.main(RulesTest.java:29)
Can you tell me why that happens??
The file is present.
Thanks.

This isn't really a Drools question just a basic java programming question.
You are trying to read your input files from the current working directory (which defaults to the root of your project in eclipse).
What you probably want to be doing is reading your files from the classpath instead. Using ResourceFactory.newClassPathResource is the way I normally go about reading my files but you can do it with the standard class loader methods as well.

Hi,
still struggling with this one (see below),
but I did a slide change in the test-code
try {
val env = new java.util.Hashtable[String, String]
env.put(Context.INITIAL_CONTEXT_FACTORY,
"bitronix.tm.jndi.BitronixInitialContextFactory")
val ctx = new InitialContext(env)
val ut1 : UserTransaction = (ctx.lookup(
"java:comp/UserTransaction")).asInstanceOf[UserTransaction]
} catch {
case ex: Exception => ex.printStackTrace()
}
(Sorry, code is in Scala, but should not be a problem to read it).
Instead of "java:comp/UserTransaction" (as written in the docs) I wrote
"comp/UserTransaction" and it works.
But since this is some test-code and I am able to do the look-up as I want
("comp/UserTransaction"), as soon as I use
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env )
I have no influence anymore (its drools-code ;-) and it looks like its
using internally "java:comp/UserTransaction".
Is there any way to change this (setting it) ?
Cheers, Rob

It's probably that your transaction manager, for an odd reason, doesn't bind with the good name;
You can do the following workaround:
Final InitialContext initContext = new InitialContext();
initContext.bind("java:comp/UserTransaction",initContext.lookup("comp/UserTransaction"));
And voila, those two jndi name should point to the same object.
I stress the fact that what I've written hasn't been tested.

Like a previous commenter said, the code below won't compile. java.io.FileReader has three constructors, none of which take a String[].
What you are asking are very, very basic Java questions. Does the NYSE seriously employ java coders who don't know the answer to these questions? Try google:
