Re: [rules-users] Run Drool Application From Command Prompt

2009-07-28 Thread Greg Barton 
heh.  I just remembered that Thread.currentThread().getContextClassLoader() can 
return null as well. :)  A good thing to do is have a utility function like the 
attached class loading utility class.  Rearrange the class loading order to 
suit your taste.

 It's unclear from your post when you get the NPE: from the
 command line, from eclipse, or when integrated with OFBiz.
 (I assume you're referring to http://ofbiz.apache.org/)
 
 It's undoubtedly a classpath issue.  Just peek at the
 source a bit.  I'm not sure what version you're using,
 but if you look at the source in the svn repo you'll see
 that line 92 of JavaDialectConfiguration is this:
 
 getClass().getClassLoader().loadClass(
 org.eclipse.jdt.internal.compiler.Compiler );
 
 See the javadoc for Class.getClassLoader() that says
 Returns the class loader for the class. Some
 implementations may use null to represent the bootstrap
 class loader. This method will return null in such
 implementations if this class was loaded by the bootstrap
 class loader.
 
 So, it looks probable that in the environment that's having
 problems, the JavaDialectConfiguration class is loaded by
 the bootstrap classloader.  What is the VM
 implementation you're using?
 
 It might be best if
 Thread.currentThread().getContextClassLoader() was used
 instead of getClass().getClassLoader() in
 JavaDialectConfiguration and elsewhere.  Devs, have an
 opinion on that?

Hi 

you r right, When I run the application (integrated with OFBiz) from

 Re: [rules-users]
 Run Drool Application
 From Command Prompt
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 It's unclear from your post when you get the NPE: from
 the command line,
 from eclipse, or when integrated with OFBiz. (I assume
 you're referring
 to http://ofbiz.apache.org/)
 
 
 
 It's undoubtedly a classpath issue.  Just peek at
 the source a bit.
  I'm not sure what version you're using, but
 if you look at the source
 in the svn repo you'll see that line 92 of
 JavaDialectConfiguration is
 this:
 
 
 
 getClass().getClassLoader().loadClass(
 org.eclipse.jdt.internal.compiler.Compiler
 );
 
 
 
 See the javadoc

Subject: Re: [rules-users] Run Drool Application From Command Prompt


Hi 

I still have not got any solution
of my problem that I posted previously. I have included all required jar
files and set proper class path .. Please do help ? 

problem:  

I am trying to integrate Drool with
ofbiz and run application from command prompt. In one way I have integrated
it properly and I am able to run it successfully.

Code : Which I was using initially

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); 

or

PackageBuilderConfiguration cfg = new PackageBuilderConfiguration();
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); 

Exception I got :

org.drools.RuntimeDroolsException: Unable to load dialect 
'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java 
:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'
at 
org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:274)

org.drools.compiler.PackageBuilderConfiguration.init(PackageBuilderConfiguration.java:176)

org.drools.compiler.PackageBuilderConfiguration.init(PackageBuilderConfiguration.java:153)
at org.drools.compiler.PackageBuilder.init(PackageBuilder.java:242)

Caused by: java.lang.NullPointerException
at 
org.drools.rule.builder.dialect.java.JavaDialectConfiguration.setCompiler(JavaDialectConfiguration.java:92)
at 
org.drools.rule.builder.dialect.java.JavaDialectConfiguration.init(JavaDialectConfiguration.java:55)
at 
org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:270

Problem I found : 
In the class JavaDialectConfiguration in jar file drools-compiler.jar there
is a method named setCompliler,  in this method Null Pointer
Exception was coming.

Solution I provided :
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. 
after that I wrote the code:

PackageBuilderConfiguration cfg = new CustomPackageBuilderConfiguration();
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(cfg);


Now application is running perfectly fine from both eclipse and command
prompt without any exception.

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
