Hi,
I have a problem when i compile a spreadsheet into a PKG. Hope you can
help me.
(Bevor this i used Guvnor to create a PKG from Spreadsheet, but i decide to
do this by my own)
The question is, how do I add this class to the package builder?
This is my Programm:
public static void main(String[] args) {
try {
final SpreadsheetCompiler converter = new SpreadsheetCompiler();
FileInputStream fis = new FileInputStream(new
File("E:\\temp\\myfirstDecTable.xls"));
final String drl = converter.compile(fis, InputType.XLS);
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(new StringReader(drl));
Package pkg = builder.getPackage();
} catch (Exception e) {
System.out.println("Error: " + e);
}
}
The Exception:
java.lang.ClassNotFoundException: Unable to find class 'KundenEntscheidung'
at
org.drools.base.ClassTypeResolver.resolveType(ClassTypeResolver.java:215)
at
org.drools.compiler.PackageBuilder.mergePackage(PackageBuilder.java:1002)

Did you import KundenEntscheidung into the spreadsheet?
Can you import and use the class in a simple handcoded DRL?

I imported the class in my DRL with the following lines:
import de.test.xml.KundenEntscheidung;
global KundenEntscheidung dieKundenEntscheidung;
But i can't use it in a simple hand coded DRL :( ...
How can i generate the DRL from the class file?

If you can't import it with a DRL import, it's either misspelled or not in
the classpath.

What do you mean? DRL is never generated from a (do you mean: Java?) class
file.

I try to add it with the following code:
PackageBuilder builder = new PackageBuilder();
Resource rs =
ResourceFactory.newClassPathResource("de\\test\\xml\\KundenEntscheidung");
builder.addDsl(rs);
But my programm throws always:
java.io.FileNotFoundException: 'de\test\xml\KundenEntscheidung' cannot be
opened because it does not exist

If this is a Java class, there is a .java file and, after compilation with
Java, a .class File. Neither one is a Domain Specific Language definition
file that could be added to the Package Builder.

But how do Guvnor do that?
In Guvnor i can upload a POJO and it integrate it into the PKG.

What are you trying to achieve?
As each email goes back and forth we appear to be moving from your original
questions to, perhaps, nearer your requirement.
If you upload a XLS decision table to Guvnor and the necessary supporting
POJO model file you should be able to build the package therefrom, without
the need for anything else.
With kind regards,
Mike
