Introduction
he Mini-Language concept in Open For Business is similar to the Gang of Four Interpreter pattern, or the Mark Grand Little Language pattern. This is also the central theme of the Building Parsers with Java book by Steven John Metsker which the OFBiz Rule Engine is based on. The idea is to create simple languages that simplify complex or frequently performed tasks.
In business software there are things that are done hundreds or thousands of times in a single application that a Mini-Language can simplify to the point of cutting implementation and maintenance times not by just 50%, but often as much as 70-90%. Yes, certain tasks will take only 10% of the effort and knowledge to perform. This makes it easier people not familiar with the software to manipulate existing or build new functionality.
Mini-Languages tend to have instructions that are more like method calls in a general purpose language. They are meant to solve a specific problem in a specific context, and are generally worthless or need to be modified for other contexts or problems.
Often this idea is implemented using a free form (BNF) or english-like syntax. In Open For Business the Mini-Languages are expressed as XML files to simplify the learning and manipulation of the syntax, in addition to making the Mini-Languages easier to write and extend.
The DTD for the simple-map-processor and simple-method XML files is in the distribution in ofbiz/core/docs/xmldefs/ofbiz/simple-methods.dtd or on the website at ofbiz.apache.org/dtds/simple-methods.dtd. These are combined into a single DTD to make it easy to use inlined simple-map-processors inside a simple-method.
To specify the DOCTYPE for a simple-map-processors XML file use the following:
<!DOCTYPE simple-map-processors PUBLIC "-//OFBiz//DTD Simple Methods//EN" "http://ofbiz.apache.org/dtds/simple-methods.dtd">
To specify the DOCTYPE for a simple-methods XML file use the following:
<!DOCTYPE simple-methods PUBLIC "-//OFBiz//DTD Simple Methods//EN" "http://ofbiz.apache.org/dtds/simple-methods.dtd">
The only difference between the two DOCTYPE definitions is the root node to use from the DTD.

Simple Map Processor Overview
The Simple Map Processor Mini-Language performes two primary tasks: validation and conversion. It does this in a context of moving values from one Map to another. The input map will commonly contain Strings, but can contain other object types like Integer, Long, Float, Double, java.sql.Date, Time, and Timestamp.
NOTE: The reference information for the simple-map-processor has been moved to annotations in the simple-methods.xsd file.

Simple Method Overview
The Simple Method Mini-Language is a simple way to implement an event that is invoked by the Control Servlet or a service that is invoked by the Service Engine. A Simple Method can be invoked through the static methods on the SimpleMethod class, or as an event through an entry in the controller configuration XML file like the following:
<event type="simple" path="org/ofbiz/commonapp/workeffort/workeffort/WorkEffortSimpleEvents.xml" invoke="update"/>
or as a service through an entry in a services.xml file like the following:
<service name="createPartyRole" engine="simple"
location="org/ofbiz/commonapp/party/party/PartyRoleServices.xml" invoke="createPartyRole" auth="true">
<description>Create a Party Role (add a Role to a Party)</description>
<attribute name="partyId" type="String" mode="IN" optional="true"/>
<attribute name="roleTypeId" type="String" mode="IN" optional="false"/>
</service>
The path or location for a Simple Method is the classpath and filename of the XML file.
In this Mini-Language you can invoke Simple Map Processors, Services and bsh scripts, perform entity related operations, and create messages to return to the caller. Specific operations can be enclosed in if blocks to execute conditionally and values or fields can be copied around in the maps, lists and method environment.
There are a number of tags which can be used to get and set attributes to/from a request or session object when called as an event or to set attributes in the result when called as a service. These operations are only applied when applicable. In other words if you include a env-to-request operation it will only be invoked when the simple-method is called as an event and a env-to-result operation will only be invoked when the simple-method is called as a service. Everything else is the same when called as an event or a service which makes it easy to write flexible logic that can be mounted/applied in various ways.
There are a number of objects that exist in the method environment when a simple-method starts or that are used as it executes to keep track of certain information. Some will exist when called as an event or a service, these are marked in the following list. Each name can be overridden using an attribute on the simple-method tag. The defaults are listed below (you can also find them in the DTD).
Here is a complete list of the attributes of the simple-method tag:
Attribute Name | Reqd? | Default Value | Description |
---|---|---|---|
method-name | Y | N/A | A name (preferably a legal Java identifier) for this method. This name must be unique for the XML file it is in as it will be used to reference this method externally. |
short-description | Y | N/A | A short description of the method for certain system error messages. |
login-required | N | "true" | Is a logged in user (UserLogin object, or login.username and login.password Strings) required to run this method? "true" or "false". |
use-transaction | N | "true" | Create a transaction if none exists for this thread? "true" or "false". |
default-error-code | N | "error" | The default error return code. |
default-success-code | N | "success" | The default success return code. |
parameter-map-name | N | "parameters" | As event: copy of request parameters As service: incoming context |
event-request-object-name | N | "request" | (as event only) |
event-response-code-name | N | "_response_code_" | (as event only) |
event-error-message-name | N | "_error_message_" | (as event only) |
event-event-message-name | N | "_event_message_" | (as event only) |
service-response-message-name | N | "responseMessage" | (as service only) |
service-error-message-name | N | "errorMessage" | (as service only) |
service-error-message-list-name | N | "errorMessageList" | (as service only) |
service-success-message-name | N | "successMessage" | (as service only) |
service-success-message-list-name | N | "successMessageList" | (as service only) |
delegator-name | N | "delegator" | A GenericDelegator object to use in the method |
security-name | N | "security" | A Security object to use in the method |
dispatcher-name | N | "dispatcher" | A LocalDispatcher object to use in the method |
Special Context Access Syntax
In strings and field names a special syntax is supported to flexibly access Map member, List elements and to insert environment values into string constants.
The ${} (dollar-sign-curly-brace) syntax can be used to insert an environment variable value in pretty much any string constant in a simple-method file. Not only can it be used to reference top-level envrionment variables, the syntax elements described below can be used to access values in sub-structures.
You can use the "." (dot) syntax to access Map members. For example if you specify the attribute field-name="product.productName"
it will reference the productName
member of the product
Map. This would be the same as specifying map-name="product" field-name="productName"
. Note that this is, of course, more flexible than a field-name/map-name combination because the Map structure can be multiple levels deep. For example if you have use the attribute field-name="products.widget.productName"
it will reference the productName
in the widget
Map which is in the products
Map.
The "[]" (square-brace) syntax can be used to access list elements. For example you can specify the attribute field-name="products[0].productName"
and it will reference the productName
of the first (position zero) element in the products
List. To make this more useful you can pull a list index from the environment using something like field-name="products[${currentIndex}].productName"
.
There are two extensions to the [] syntax that can be used when refering to an environment location that is the target of an operation. If you do not include a number between the square braces the value will be put at the end of the list. If you put a "+" (plus sign) in front of the number between the square braces (ie: [+2]) it will insert the value before that position in the list instead of replacing the value at that location. For example, specifying [+0] would insert the value at the beginning of the list.
In fact, you can use the ${} syntax to substitute any string or other value at any location in a field-name or other string constant. So, you could even reference a Map member named in some other environment variable. For example you could use field-name="products[${currentIndex}].${currentMember}"
to achieve this effect.
Okay, enough of the general stuff, here is a catalog and description of the available operations.
Call Operations
call-map-processor
The call-map-processor tag invokes a simple map processor from an existing map, creating a new map or adding to an existing one if the named out-map already exists. Resulting messages are added to the named list, and a new list is created if a list with the given name does not yet exist. Note that all lists and maps exist in the same context and must have unique names.
An inline simple-map-processor can be used by putting a simple-map-processor tag under the call-map-processor tag. If both an external and an inline map-processor are specified, the external one will be called first, allowing the inline one to override its behavior.
Attribute Name | Required? | Description |
---|---|---|
xml-resource | N | The full path and filename on the classpath of the XML file which contains an external map processor to execute. This is only required if an external map processor is desired. |
processor-name | N | The name of the external map processor to execute in the specified xml-resource. This is only required if an external map processor is desired. |
in-map-name | Y | The name of a map in the method environment to use as the input map. |
out-map-name | Y | The name of a map in the method environment to use as the output map. Will be created if it does not exist already. If already exists will be added to in place. |
error-list-name | N | The name of a list in the method environment that the error messages will be added to. Will be created if it does not exist. Defaults to "error_list". |
Sub-Element Name | How Many | Description |

call-service
The call-service tag invokes a service through the Service Engine. If the specified error code is returned from the service, the event is aborted and the transaction in the current thread is rolled back. Otherwise, the remaining operations are invoked.
The result-to-request and result-to-session elements will be IGNORED when called in a service context. So, they are ONLY used when called in an event context.

calculate
The calculate tag performs the specified calculation and puts the result in an object in the field of the specified map (see the calculate element attribute descriptions above). The type of the object can be specified with the type attribute, but defaults to Double.
The calculate tag can contain calcop and number tags, and the calcop tag can also contain these two tags to enable nested calculations.
Each calcop tag has three attributes: operator, map-name and field-name. Only the operator is required. The operator specifies the operation to perform on the given field and nested calcops and numbers. It must be one of the following: get | add | subtract | multiply | divide | negative.
Regardless of the operator the action is very similar. It translates to a formula like the following: (V1 [operator] V2 [operator] V3)
. In other words a final result is calculated by applying the operator to the values in the order they are specified. If a field-name (and optionally map-name) is specifies on the calcop tag that field will be used as the first value, otherwise the first nested calcop or number will be the first value.
The get operator is just an alias for add. It adds all of the values under it. Likewise the negative operator is almost an alias for subtract, with the exception that the first value is negated instead of left positive. For convenience the calculate tag itself acts like an add, in other words the calcops and numbers under it are all added together.
Attribute Name | Required? | Description |
---|---|---|
map-name | N | The name of the map in the method environment. If not specified the field-name will be used to get the field from the method environment. |
field-name | Y | The name (key) of the map field to use. |
type | N | The object type to put into this field. Can be: Double | Float | Long | Integer. The default is Double. |
Sub-Element Name | How Many | Description |
---|---|---|
calcop | 0 to many | This tag is used to apply an operator in the calculation. It can have calcop and number tags nested under it, making it also act like a parenthesis. It has three attributes: operator, map-name, and field-name. These are described below. |
number | 0 to many | This is used to put a numeric constant (a number) into the calculation. It has one attribute: value. This must be a properly formatted number or an error will result. |
Here is an example of an XML snippet that performs the calculation a=b+(((c+x+2)*-d)/e)
, or in Reverse Polish Notation (a little bit closer to the resulting XML, and the notation used in the Rule Engine) a=+(b,/(*(+(c,x,2),-d),e))
. Here is the XML:
<calculate field-name="a">
<calcop operator="get" field-name="b"/>
<calcop operator="divide">
<calcop operator="multiply">
<calcop operator="add" field-name="c">
<calcop operator="get" field-name="x"/>
