[Ulf Dittmer]

Welcome to JavaRanch.

error is displayed.

What error is that? Is there a stack trace to go along with it?

[Kebede Abdi]

thanks alot! it is really amessing to get a reply soon.
the error is :
rec deallocate is unreported exception javax.speech.EngineException;mustbe caught or declared to be thrown

[Rob Spoor]

That's a compiler error. javax.speech.EngineException is a checked exception, so you should follow the instructions in the error message: catch it (try-catch block) or add it to the throws clause of your method.

[Kebede Abdi]

thanks friends !

i fix that error with try-catch block.like this
try{
rec.deallocate();
System.exit(0);
catch(Exception ex){ex.fillInstackTrace();}

but what happened to this

public void resultAccepted(ResultEvent e)

there is red underline on resultAccepted
i ignore it and run the program but there is error on line 35 as

java.lang.NullPointerException
at javaapplication19.HelloWorld.main(HelloWorld.java:35)

My final question: before the HelloWorld example 0n the site
http://java.sun.com/products/java-media/speech/forDevelopers/jsapi-guide/Recognition.html#7408
there is a grammar and it says Place this grammar into a file
is that important if so how can i do that? i'm really new to it. If there is another information which i must know about JSAPI please help friends thanks!

[Rob Spoor]

Although the problem occurs when calling jsapi, the real problem is basic Java - exception handling, missing methods, etc. Moving to JiGb

[Campbell Ritchie]

Please tell us exactly where you get the NullPointerException, and then go through the line and see which object references might be null.

[Bert Bates]

consider making this an intermediate thread...

[Campbell Ritchie]

I agree with Rob that finding the location of an NPE is a beginner's topic.

[Kebede Abdi]

For what Campbell asks the NullPointerException is at a line rec.allocate();

[Campbell Ritchie]

Assuming there is nothing else on the line, this suggests the rec object was null at that point.

Have you instantiated rec correctly? Probably in the constructor.

Has rec been reassigned to null?

Has anything been serialised and rec been lost on the way?

Has rec somehow been passed as null?

There is a good chance that you will know how to sort out the NPE when you have answered those questions.

Then let's see whether any problems remain; if it is a JSAPI problem still, it might then be necessary to move this thread again.

[Kebede Abdi]

Ok! friends i will fix it
But please tell me how to work with JSGF and JSAPI on netbeans
to load the grammar thanks for help!

[Kebede Abdi]

hi!!
please tell me about them!

Dawit,
We have lots of forums here, arranged by category.
To get the most of the ranch, always remember to choose a proper forum.

Since your new question is related more to IDEs I suggest you post it here to get a better response
Also please start a new thread for a new question.

[Kebede Abdi]

THANKS Maneesh and thankyou all!
i try my best but...
Any one who run the HelloWorld example in netbeans
the example is on the site
http://java.sun.com/products/java-media/speech/for...pi-guide/Recognition.html#7408
please show me. I badly need it, after i know it well i'm going to use jsapi for another appliction .
please from the scratch.
Thanks for bighearted help that is why i feel free!!!

[Kebede Abdi]

hello friends !!!
i fix the NPE error by running my program on diffirent PC .

i use You may be an all the neccerary steps for file reader

FileReader reader = new FileReader("C:/Documents and Settings/dawi2137/Desktop/hello.gram");
RuleGrammar gram = rec.loadJSGF(reader);

Now i get problem on FileReader like this
java.io.FileNotFoundException: C:\Documents and Settings\dawi2137\Desktop\hello.gram (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:106)
at java.io.FileInputStream.<init>(FileInputStream.java:66)
at java.io.FileReader.<init>(FileReader.java:41)
at javaapplication1.HelloWorld.main(HelloWorld.java:31)
how can i fix it?

[Maneesh Godbole]

The problem is here

java.io.FileNotFoundException: C:\Documents and Settings\dawi2137\Desktop\hello.gram (The system cannot find the file specified)

Make sure the file exists.

[Kebede Abdi]

I create the file and save in the path mentioned as hello.gram!

And i'm sure that the file is regular file not a directory.

[Kebede Abdi]

now the file is allready read but nowthe error is
the grammar name is not specified at public what is happing
i follow all the procedure

[Campbell Ritchie]

No longer a beginner's topic.

Moving.

[Kebede Abdi]

Sorry for disterbance and THANKS A lot for being with me!
