Hi kedar, Of course, I do not know what you are trying to achieve in the end, but from the limited information that I have, I think I can agree with manstis that there are 2 options. 1) Download and install Guvnor, which is a UI to edit rules and may be exaclty what you want. 2) Write an application that constructs a text file, based on some inputs and save the text file as myveryimportantrules.drl I have never tried option 2, but it doesn't seem very hard. kedar vyawahare wrote: Thanks for reply. yaa i want exactly the same my U.I should generate the DRL file .But I dont know how to generate a DRL file through U.I.

Re: [rules-users] .drl(rule)file creation
You could look into using org.drools.ide.common.client.modeldriven.brl.RuleModel (in droolsjbpm-ide-common). This is the basic model used by all of the guided editors before translating it into DRL with org.drools.ide.common.server.util.BRDRLPersistence (in droolsjbpm-ide-common too). There are a lot of Unit Tests that illustrate construction of DRL using this approach.

for( VerifierError error: errors ){

Re: [rules-users] Problems with Guided Rule Editor in Eclipse

The plugin is incomplete/buggy and shows errors but rules are correct (you can compile and run them). This problem is the same since version 5.0. There is a JIRA for that since then ... I don't know when a fix is planned, but my feeling is that nobody uses the guided editor under eclipse (dsrl editor works well and provide completions on facts and DSL sentences).

I have created a Drools Project using the basic Hello World example for starters. Ive created a class called Item with 3 attributes itemPrice (float), ItemNumber (int), and itemDescription (String) with getters/setters. I do a New-Drools-Guided Rule to create a .brl file called GuidedRule.brl and get the drools.package created automatically. In drools.package, I add package com.sample; and import com.sample.Item; and save it. Then I go over to GuidedRule.brl and create a simple rule in the guided editor (this is the DRL view of it): rule GuidedRule dialect mvel when item : Item() then item.setItemDescription(New Description); end When I click save I get errors. On the Generated drl (read only), I get two problems - BuildError: Unable to build _expression_ for 'consequence': Failed to compile: 2 compilation error(s): - (1,4) unqualified type in strict mode for: item - (1,44) unable to resolve method using strict-mode: java.lang.Object.setItemDescription(java.lang.String) ' item.setItemDescription( "New Description" );' On the brl source view, I get an error at the attributes - BuildError: Unable to resolve ObjectType 'Item' It seems to not be able to see my class, which is public, belonging to the same package, and included as an import in drools.package. I can get the rule to work if I dont reference Item (simple eval(true) in the LHS, for example). I am running Drools 5.1.1 on Eclipse 3.5.

Re: [rules-users] Drools verifier
Hi Wolfgang,
Yes, you are absolutely right about the path mistake. Can't believe I missed
that. Fixing it removes the errors from the verifier.
However, it still does not return the expected outputs...
System.out.println(result.getVerifierData().getAll().isEmpty()); = returns
false, which is as expected
But the following statement still does not return anything.
for (VerifierMessageBase base : result
.getBySeverity(Severity.WARNING)) {
System.out.println(base);
}
I'm sorry to take so much of your time, I really appreciate your efforts.

Frank

No you can't ... A DSL sentence stands for a whole condition (or action). You can't really add contraints in it. One thing that could work is to define DSL phrase starting with - (see documentation) and add them just under the main DSL sentence. But careful using that, as DSL phrase are not filtered according to their context, your DSL may become complex and a bad usage (which becomes more and more frequent as the DSL grows) will produce rules that does not compile, or worse, that does silly things ... I think I should be able, otherwise how could I write an 'OR' condition between this 2 lines? You must first create a OR condition (something like one of the following is true :), which will create a container for sub-conditions. You can then insert the condition inside this OR container. Also, enums are displayed as a simple selection list (combo box) in the DSL sentence. Is it possible to have multi-selection, effectively getting a list of selected values to be used inside the rule? I don't think so To gain flexibility on rules coding, you should consider not using DSL, or use it when you are really forced to (it is my opinion, as discussed in this thread : http://drools-java-rules-engine.46999.n3.nabble.com/Who-writes-your-rules-Dev-vs-BA-td2398166.html) ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Drools verifier
Can you make few rules for us to test this with.
I have to say that the verifier is not perfect when it searches for redundancy,
so your rules might be too complex for it at the moment.

Re: [rules-users] Drools verifier
Hi, Thanks all for your replies. I forgot I had already uncommented the RHS of a rule, whic onviously did not return a warning. When I comment it, this warning is displayed. Sorry to bother you with this trivial problem. Redundancy, however, isn't detected yet. Neither are the gaps [temperature = 0] and [precipitation != snow] I am assuming this has more to do with the rules, than it has to do with drools verfier. These are the redundant rules: = rule Rule 1 salience 200 agenda-group group1 lock-on-active true when $w : Weather( temperature 0 || precipitation == Weather.SNOW ) $a : Assignment( status == Assignment.INACTIVE) then System.out.println(This rule fired); end rule Rule 2 salience 200 agenda-group group1 lock-on-active true when $w : Weather( temperature 0 || precipitation == Weather.SNOW ) $a : Assignment( status == Assignment.INACTIVE) then System.out.println(This rule fired); end rule Rule 3 salience 200 agenda-group group1 lock-on-active true when $w : Weather( temperature 0 || precipitation == Weather.SNOW ) $a : Assignment( status == Assignment.INACTIVE) then System.out.println(This rule fired); end -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-verifier-tp2681002p2688101.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

I am able to open your process without errors in both Eclipse as well as
in Oryx after importing it to Guvnor. Here is what I have tested your
process with:
Guvnor: latest from trunk (https://github.com/droolsjbpm/guvnor) as well
as the version that comes with jBPM5-Final (
http://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.0-Final/ )
and also the latest snapshot
(http://hudson.jboss.org/hudson/job/jBPM5/lastSuccessfulBuild/artifact/target/)
Oryx: Latest version
(http://people.redhat.com/tsurdilo/oryx/1.0.0.049-SNAPSHOT/), you should
download designer-1.0.0.049-SNAPSHOT-jboss.war
http://people.redhat.com/tsurdilo/oryx/1.0.0.049-SNAPSHOT/designer-1.0.0.049-SNAPSHOT-jboss.war
and rename it to designer.war before deploying.
You may be using some older versions, if you let me what what they are
then I can test with those as well.

Hello everyone,
I am a newbie to Guvnor. I have a set of .dslr files with .dsl to
translate
them.
I know I can just copy and paste .dslr file and .dsl file.
However, the
problem is that
I call external function within .dsl file and when I try to
validate the
dsl, it complains for not having the method.
ex)
[condition][Trade]xpathMatch {xpath}=trade : Trade( type ==
Trade.TRADE_TYPE ) and eval( DslHelper.xmlContentMatches(trade,
{xpath}) )
This is my condition and it has all models like Trade. However, it
complains
about not having DslHelper function. This function has so many
dependencies
that I cannot upload through POJO jar.
Is there any elegant way to solve this problem?
Thanks in advance :)

[rules-users] Open file leak in Drools Compiler
I am running Drools (actually JBoss Rules 5.1.0 ) in Glassfish.
My deployable is an EJB that uses a StatelessKnowledgeSession to run
some rules that I get from a KnowledgeAgent that has a Changeset with a
.drl in it.
Therefore, I have placed the drools compiler into the deployable and it
all appears to work.
Glassfish has a clever little mechanism that, when you unload a
deployable that had some open streams, it tells you all about it (and
kindly closes them).
Glassfish is reporting that InputStreams are being left open that were
opened in the isPackage() method of
org.drools.commons.jci.compilers.EclipseJavaCompiler.
That method has the following code in it:-
final InputStream is =
pClassLoader.getResourceAsStream(ClassUtils.convertClassToResourcePath(pClazzName));
if (is != null) {
return false;
}
So, when is is not null (i.e. open), it is forgotten about and not closed.
Isn't this a potential file handle leak?

Re: [rules-users] Open file leak in Drools Compiler
Yes, but it's not a full blown leak. Wrapping stream use in a try/finally
block is best. Feel free and open a JIRA to fix it. There may be other
instances.

Isn't it regarded as bad practice to
rely on the finalize() method
called by the garbage collector to release such resources?

I am running Drools (actually JBoss
Rules 5.1.0 ) in Glassfish.
My deployable is an EJB that uses a
StatelessKnowledgeSession to run
some rules that I get from a KnowledgeAgent that
has a
Changeset with a
.drl in it.
Therefore, I have placed the drools compiler into
the
deployable and it
all appears to work.
Glassfish has a clever little mechanism that, when
you
unload a
deployable that had some open streams, it tells
you all
about it (and
kindly closes them).
Glassfish is reporting that InputStreams are being
left
open that were
opened in the isPackage() method of
org.drools.commons.jci.compilers.EclipseJavaCompiler.
That method has the following code in it:-
final InputStream is =
pClassLoader.getResourceAsStream(ClassUtils.convertClassToResourcePath(pClazzName));
if (is != null) {
return false;
}
So, when is is not null (i.e. open), it is
forgotten
about and not closed.
Isn't this a potential file handle leak?

Re: [rules-users] Open file leak in Drools Compiler
This is JCI code that we inline. We should probably check if there is a
new JCI version that fixes the problem if it is indeed a problem.
Can I ask you please to open a JIRA with the info you reported here?

Re: [rules-users] Basic doubt regarding Drools Fusion - @expires
By default, Drools does not start any internal thread, so that you can embed it in non-multithread applications or in JEE containers. That means that the actual release of events in such cases depends on triggers. In your example, after 1h has passed, whenever something happens to the session (a new rule is fired, a new event is inserted, the session clock is advanced, etc), the event will be expired as part of the action. Remember though that it only happens when running in STREAM mode. In CLOUD mode, event garbage collection does not make sense and will not happen. Edson 2011/3/16 Makewise - Vitor Rui Mendonça vitor.mendo...@brisa.pt Hi all! I’ve got a really basic doubt… I’ve read several documentation regarding it but I think I need some advice here… Imagine that I have an event: *declare* A @role( event ) @expires( 1h ) *end* On my Java code, I call “fireAllRules()” method every time that I put an event into the working memory. My doubt: When does event A expires? a) One hour after it was inserted (time-based and without the “fireAllRules()” method call) or b) by calling “fireAllRules()” method (event-based) T.I.A.

[rules-users] drools design question
Hi, We are developing an insurance application and we have decided to use drool rules for our business rules Now, we could have global business rules(applies to all states), specific to state, specific to factor X, specific to factor Y etc. This way we are expecting many drl files. Now, when the application runs, we would know the values for state, factor X, factor Y etc. and using these values we would determine(using database) which drl files to load dynamically and just run the rules in those drls. Is this approach recommended? Do you have any suggestions?

[rules-users] Custom dates with @date-effective and @date-expires
Hi, Can I use any arbitrary date for the drools execution so that correct rules are fired based on not current date but any arbitrary date? This is in the context of @date-effective and @date-expires metadata that can be specified as part of a rule. Drools expert documentation seems to imply that this metadata uses current date though I am not clear what current date (system date?) means.

Re: [rules-users] Problems with Guided Rule Editor in Eclipse
In experimenting with my own Guided editor files I am trying both the Fact and Condition sentences to use the Guided editor in Eclipse without typing any DRL or Java by prospective business users. I have a Java project with classes that are imported by a rule project with drools.package (and the imports), a dsl file, and a guided rule (.brl) file. The most obvious odd thing is that when using while the Fact menu, the menu is populated correctly, but my int field is being surrounded by quotes in the translated drl (i.e., it is translated as a string). This is despite the fact that relational operators are presented for the field, but string operators for string fields. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Problems-with-Guided-Rule-Editor-in-Eclipse-tp2683535p2692235.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] [Urgent] Error in ontext assist in DSLR Editor
I am seeing this behavior in 5.1.1 - it is as if the context sensitivity is
far to greedy for replacement.
Since this may not have been clearly understood from the original posting,
if I have
There is an {Instance} with field of {value}
and my cursor is at the end of the line and I select, using control-space in
the editor
whose name is {name} it produces
Twhose name is {name} instead of appending whose name is
{name}
Is this intended behavior? It effectively prohibits nesting dsl expressions
when using the dslr editor. This seems like something a JIRA would have
been written on to handle by now.
