Problem I found : </b><br>
In the class JavaDialectConfiguration in jar file drools-compiler.jar there
is a method named "setCompliler", in this method Null Pointer

<br>
Solution I provided :</b></font><font size=3> </font><font size=2 face="Trebuchet MS"><br>
In my application I created my custom class CustomJavaDialectConfiguration
by extending to class JavaDialectConfiguration, In this class I overrided
the method setCompiler. My method was exactly same as that of method setCompiler
in JavaDialectConfiguration . To call my dialect class I also overrided
the method "addDialect" of PackageBuilderConfiguration class
. For that I created class CustomPackageBuilderConfiguration by extending
to PackageBuilderConfiguration. <br>
after that I wrote the code:</font><font size=3> </font><font size=2 face="Trebuchet MS"><br>
<br>
PackageBuilderConfiguration cfg = new CustomPackageBuilderConfiguration();</font><font size=3>
</font><font size=2 face="Trebuchet MS"><br>
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(cfg);</font><font size=3>
<br>
</font><font size=2 face="Trebuchet MS"><br>
<br>
Now application is running perfectly fine from both eclipse and command
prompt without any exception.</font><font size=3> </font><font size=2 face="Trebuchet MS"><b><br>
<br>
I want to know as my overrided method "setCompiler" was exactly
same then why I had to override method, and In original code (ie in drools-compiler.jar
file) why it was giving exception ??? Was that due to class
lader or something else ?? Please do help in this regard ....</b></font><font size=3>
