Hi Giovanni,
The classpath shows the commons jar added under UserEntries.
I am getting another error when I try running the program now :
Exception in thread "main" java.lang.NoClassDefFoundError:
org/drools/brms/server/util/BRXMLPersistence
at com.org.RulesTest.main(RulesTest.java:40)
Caused by: java.lang.ClassNotFoundException: org.drools.brms.server.util.BRXMLPersistence
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)
... 1 more
This was not coming till now.
The exception come at the line when the .brl file is to be processed.
I am not able to figure out. I tried googling the error. But no use!
Please help!
Thanks
M

Are you launching the application from within eclipse?
Have you checked the classpath of the launch configuration? You can see it
by right-clicking the .java file and then selecting "run as --> run
configurations..."
Does it show the commons jar?

Hi,
I just tried everything I could think of but still getting error.
Using following code for converting from .brl file to .drl file:
File file = *new* File(rulesFiles);
String brl = *null*;
*try*{
BRXMLPersistence read = (BRXMLPersistence)
BRXMLPersistence.*getInstance*();
BRDRLPersistence write = (BRDRLPersistence)
BRDRLPersistence.*getInstance*();
brl = FileUtils.*readFileToString*(file);
System.*out*.println("File content: " + brl);
String outputDRL = write.marshal(read.unmarshal(brl));
String drlFilePath = "drlFile.drl";
File drlFile = *new* File(drlFilePath);
FileUtils.*writeStringToFile*(drlFile, outputDRL);
addRulesToThisPackage.addPackageFromDrl(*new*
InputStreamReader(RuleRunner.*class*
.getResourceAsStream(drlFilePath)));
}*catch* (IOException e) {
e.printStackTrace();
}
I have added the org.apache.commons .jar files to the classpath.
It contains a FileUtils.java file which I added to the classpath.
Now the error I get when I run the program is :
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
FileUtils cannot be resolved
at com.org.RuleRunner.loadRuleFile(*RuleRunner.java:70*)//
at com.org.RuleRunner.loadRules(*RuleRunner.java:45*)
at com.org.RuleRunner.runStatelessRules(*RuleRunner.java:102*)
at com.org.RulesTest.main(*RulesTest.java:40*)
I don?t understand why still I am getting the error.
RuleRunner.java:70 is : brl = FileUtils.*readFileToString*(file);
Is there any thing else I could use ?/ Could you give me a hint??
Thank you
M
