Ignore the last post, It was a silly mistake on my part .. sorry about that.

It makes no difference if I use run the DTABLE without KnowledgeAgent:

Jan 9 14:08:19: Unable to Analyse Expression request == "/":
Jan 9 14:08:19: [Error: unable to resolve method using strict-mode: ultra.Default.ultra.MYHTTPD.request()]

Jan 9 14:08:19: [Near : {... request == "/" ....}]
Jan 9 14:08:19: ^
Jan 9 14:08:19: [Line: 7, Column: 10]

Drools tries to resolve the property request with a call to ultra.Default.ultra.MYHTTPD.request() when it should look for ultra.Default.ultra.MYHTTPD.getRequest().

Thanks for your answer.

I have now tried to load the XLS without the KnowledgeAgent(see createKnowledgeBase() below).

This time I got class loading problems( see stack trace below).
This only happens when I load a XLS decision table, If I load a DRL rules file it runs fine without classloading issues.

I use a custom classloader that is configured with the KnowledgeBaseConfiguration, I can see that drools is trying to load the rule classes from the custom classloader when I run DTABLE but not when I run DRL.

From the stacktrace it seems as if it's using CompositeClassLoader though.

conf.setStrict(false);

String compilerDumpDir = context.getCompilerDumpDir();

if (compilerDumpDir != null && !compilerDumpDir.isEmpty())

{
pconf.setDumpDir(new File(compilerDumpDir));
}


KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(kBase, bconf);


  kbuilder.add(ResourceFactory.newFileResource("/tmp/templatetest.xls"),

ResourceType.DTABLE,

dtableconfiguration);

Have you tried load the XLS into a KnowledgeBase without using a KnowledgeAgent?

Trying to narrow down where the issue might be will help (everyone) tremendously.

Hello!

I'm using a knowledgeagent to point out a changeset XML which contains the
following DTABLE:

...
<resource source='file:/../templatetest.xls' type='DTABLE' />
...

when I compile I get the following error:

Unable to Analyse Expression request == "/":
[Error: unable to resolve method using strict-mode:
ultra.Default.ultra.MYHTTPD.request()]
[Near : {... request == "/" ....}]
^
[Line: 7, Column: 10] : [Rule name='print the incoming query_9']

The weird this is that MYHTTPD class is a javabean and contains getRequest
and setRequest methods.
notice that it tries a no getter method
ultra.Default.ultra.MYHTTPD.request().
If I do the same logic from a normal DRL rules file it works fine.
MYHTTPD is generated so I cannot past the source here, but it's correct and
as I mentioned working in DRL files.

this is how the XSL file looks like:

RuleSet A rules test
Import ultra.Default.ultra.MYHTTPD

RuleTable print the incoming query
CONDITION ACTION
MYHTTPD
request System.out.println($param);
Matcher Logger
/ "webserver root"

Anybody who knows what this is about?

Thanks // Olle
