[rules-users] xls decisiontable - unable to resolve method using strict-mode

[ollem]

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

RuleTableprint the incoming query   
CONDITIONACTION
MYHTTPD 
request  System.out.println($param);
Matcher  Logger
/webserver root

Anybody who knows what this is about?

Thanks // Olle

[rules-users] cron timer not running

[ollem]

Hi!

I have a problem with getting cron based timers to start running.
The rules compiles just fine it's just that the timer never executes the
rule.
When I use timer ( int: 1m ) it works fine but not with cron timers.
My rule looks like the following:

rule whatever
timer(cron:* 0/1 * * * ?)
when

[rules-users] ASMAccessorImpl classloader issue?

[ollem]

Hi!

I'm trying to use jackson to deserialize JSON to declared types.
When I do that I get classloading problems when inserting the fact into
knowledgespace.
I have explicitly set the context classloader to
org.drools.rule.JavaDialectRuntimeData$PackageClassLoader during
deserialization.
The problem only occurs when I insert facts at a high rate. I use a http to
send data that will be inserted as facts and when I send only 100 facts I
have no problems, when I step this up to around 500 I get the following
stacktrace. Has anybody seen anything like this? Please help me!

Best Regards // Olle Mårtensson

[rules-users] Custom file format

[ollem]

 
I'm in a situation where my domain models are stored with automatically
generated package and class names. I'm looking for a way to somehow map a
fake import to the real import att compile time.
I guess a dialect is not the way since it only deals with the rules part.
I'v been thinking about using ResourceTypeBuilder.

Any ideas ?

Thanks // Olle
