Here is my Fitnesse page:

!path C:\Users\Jayasree\workspace\Selenium\bin\Sample
!|import|
!|add|

My fixture code:
package Sample;
import fit.ColumnFixture;
public class add extends ColumnFixture{
public int a;
public int b;
public add(int a,int b)
{
this.a=a;
this.b=b;
}
public int getA() {
return a;
}
public void setA(int a) {
this.a = a;
}
public int getB() {
return b;
}
public void setB(int b) {
this.b = b;
}
public int sum() {
return a+b;
}
}
I'm getting the following error:
variable defined: TEST_SYSTEM=slim

How can I solve this?
The import table requires the names of the packages to import:

interfaces
abstract class Adder<T> {
T add(T a, T b);
}
abstract class Multiplier<T> {
T multiply(T a, T b);
}
abstract class Displayer<T> {
void display(T a);
}
An implementation that just happens to implement all three.
class IntImpl implements Adder<int>, Multiplier<int>, Displayer<int> {
#override
int add(int a, int b) {
return a + b;
}
#override
int multiply(int a, int b) {
return a * b;
}
#override
void display(int a) {
print('printing: ${a}');
}
}
A consumer that needs support for two of the interfaces.
But, I could not find how to declare such a thing.
class DisplayingAdder<T, K extends Adder<T>> {
final K engine;
DisplayingAdder(this.engine);
T addAndDisplay(T a, T b) {
final r = engine.add(a, b);
// How do I change DisplayingAdder class parametrization to make the next line functional?
// engine.display(r);
return r;
}
}
Code to exercise the above
void main() {
final e1 = IntImpl();
final da = DisplayingAdder(e1);
da.addAndDisplay(3,4);
}
Not sure what can be changed to allow the generic parameter to declare support for more than one abstract class.
You can't restrict a generic type to a type that implements multiple supertypes. The best you're going to have to do is separate engine into an object that implements Adder and an object that implements Displayer, then pass the instance of IntImpl to both. (This is more scalable anyway since it also allows you to pass different values to each if you wanted.)
class DisplayingAdder<T, A extends Adder<T>, D extends Displayer<T>> {
final A adder;
final D displayer;
DisplayingAdder(this.adder, this.displayer);
T addAndDisplay(T a, T b) {
final r = adder.add(a, b);
displayer.display(r);
return r;
}
}
void main() {
final e1 = IntImpl();
final da = DisplayingAdder(e1, e1);
da.addAndDisplay(3,4);
}
I am writing a small "language" to create javascript code. Essentially it is hiding/showing some html form elements. But i need to add custom javascript code to some, e.g. what to do on a click-event.
Action:
'on' eventName=ID 'do' code=CODE
;
terminal BEGIN: "!$";
terminal END: "$!";
terminal CODE:
BEGIN -> END
;
I can now create an Eclipse-Plugin and code in my language, but the value of the field code contains the BEGIN and END characters.
on eventName do !$
var x = thisIsJavaScript();
console.log(x);
$!
My value is:
!$
var x = thisIsJavaScript();
console.log(x);
$!
I want only the part in between without !$ and $!.
Any hint is appreciated.
Thank you very much!
you should write a valueconverter for your terminal rule
import org.eclipse.xtext.common.services.DefaultTerminalConverters;
import org.eclipse.xtext.conversion.IValueConverter;
import org.eclipse.xtext.conversion.ValueConverter;
import org.eclipse.xtext.conversion.ValueConverterException;
import org.eclipse.xtext.nodemodel.INode;
import com.google.inject.Inject;
public class MyDslConverters extends DefaultTerminalConverters {
#Inject
private CODEValueConverter codeValueConverter;
#ValueConverter(rule = "CODE")
public IValueConverter<String> CODE() {
return codeValueConverter;
}
public static class CODEValueConverter implements IValueConverter<String> {
#Override
public String toValue(String string, INode node) throws ValueConverterException {
return string.substring(2, string.length()-2);
}
#Override
public String toString(String value) throws ValueConverterException {
return "!$" + value + "$!";
}
}
}
I am trying to match a Java method name to a regex, but I'm not sure how to do it in Rascal. I want to match a method whose name starts with test (such as JUnit 3 test cases) and transform it to a JUnit 4 test case, with the #Test annotation and removing the test prefix. My code looks like this:
public tuple[int, CompilationUnit] refactorJUnitTestCaseDeclaration(CompilationUnit cu) {
int total = 0;
println(cu);
CompilationUnit unit = visit(cu) {
case(MethodDeclaration)`public void <Identifier name>() <MethodBody body>`: {
if(/test[A-Z]*/ := name) {
total += 1;
newName = name[4..];
insert (MethodDeclaration)`#Test public void <Identifier newName>() <MethodBody body>`;
};
}
};
return <total, unit>;
}
This code results in the following error:
Expected str, but got Identifier
Is there any way to access the name method identifier as a String, so I can try to match it? If not, whats the best way to accomplish this task?
The regex pattern operator wants to match against strings only, so you have to map the parse tree of name (which is of type Identifier) to a string like so: "<name>".
Similarly, to splice back the new name string into the location of an Identifier you have to map it back to Identifier like so: [Identifier] newName.
The end result looks like this:
public tuple[int, CompilationUnit] refactorJUnitTestCaseDeclaration(CompilationUnit cu) {
int total = 0;
println(cu);
CompilationUnit unit = visit(cu) {
case(MethodDeclaration)`public void <Identifier name>() <MethodBody body>`: {
if(/test[A-Z]*/ := "<name>") {
total += 1;
newName = [Identifier] "<name>"[4..];
insert (MethodDeclaration)`#Test public void <Identifier newName>() <MethodBody body>`;
};
}
};
return <total, unit>;
}
You can also directly match the tail out with a named group:
public tuple[int, CompilationUnit] refactorJUnitTestCaseDeclaration(CompilationUnit cu) {
int total = 0;
println(cu);
CompilationUnit unit = visit(cu) {
case(MethodDeclaration)`public void <Identifier name>() <MethodBody body>`: {
if(/test<rest:[A-Z]*>/ := "<name>") {
total += 1;
newName = [Identifier] rest;
insert (MethodDeclaration)`#Test public void <Identifier newName>() <MethodBody body>`;
};
}
};
return <total, unit>;
}
I'm adjusting my app to work in Websphere 8.5.5 and i found that my app doesn't inject EJB but the same app in Jboss 7.1.1 works ok.
After tha, i create a dummy app and it doesn't work(only add 2 Integers).
Can someone help me?
Edited:
package resources;
import javax.annotation.PostConstruct;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import co.com.prueba.local.SumadorLocal;
#ManagedBean
#ViewScoped
public class SumadorUI {
private Integer a;
private Integer b;
private Integer c;
#EJB
private SumadorLocal sumadorLocal;
#PostConstruct
private void init(){
System.out.println("Init :"+sumadorLocal);
}
public String sumar(){
c=sumadorLocal.sumador(a, b);
return null;
}
public Integer getA() {
return a;
}
public void setA(Integer a) {
this.a = a;
}
public Integer getB() {
return b;
}
public void setB(Integer b) {
this.b = b;
}
public Integer getC() {
return c;
}
public void setC(Integer c) {
this.c = c;
}
}
UPDATED:
I add new EJB to testing if the problem injection is in ManagedBean or all app, and only the problem is ManagedBean.
After read and tested, i found a solution. In this link explain how create a implementation of DiscoverableInjectionProvider (Class that help to inject EJB instance) https://developer.ibm.com/answers/questions/176344/injection-of-stateless-ejbs-into-jsf-managed-beans.html. With this class and adjust web.xml works for me.
I have many queries with many select fields and some nested entities. This a simplified version of nested entity structure:
public class OuterEntity{
private String name1;
private String name2;
private MiddleEntity middle;
//... get/set..
}
public class MiddleEntity{
private String surname1;
private String surname2;
private InnerEntity inner;
//... get/set..
}
public class InnerEntity{
private String nickname1;
private String nickname2;
//... get/set..
}
All entities have 1:n relationship, so I can write a single long query to get all data. I want to avoid multiple queries to get each single entity separately.
select
o.name1
o.name2
m.surname1
m.surname2
i.nickname1
i.nickname2
from outertable o
join middletable m on m.id=o.middle
join innertable i on i.id=m.inner
I wish to have a RowMapper for this mapping using column names aliases that can get and nest all entity. Maybe I can describe all nesting path with columns alias:
select
o.name1 as name1
o.name2 as name1
m.surname1 as middle_surname1
m.surname2 as middle_surname2
i.nickname1 as middle_inner_nickname1
i.nickname2 as middle_inner_nickname2
from outertable o
join middletable m on m.id=o.middle
join innertable i on i.id=m.inner
Do you think is it possibile? Does jdbctemplate provide something for this need?
I'm not asking to code a new RowMapper for me, I just want to know if exists something or better solution becase I think it is a very common problem
My actual solution is to get entities separately (one query per entity) and map them with BeanPropertyRowMapper. Another solution could be to write a different RowMapper for each query, but I will use this as last chance because I should write many different mapper for a common logic.
ORM frameworks like Hibernate is not an option for me.
I did not find nothing for now, I tried to write a custom BeanWrapper base on BeanPropertyRowMapper soruce.

* BeanRowMapper for nesting beans of 1:n entity this uses query aliases to build entity nesting.
* Field names should be exactly the same of bean property, respect cases and do not use underscore for field names
* "id" columnname/alias is used to check if a nested entity should be null.
*
* example:
* select
* a.p1 as property1
* b.id as entityname_id //<-- if this is values is null, the entity will be null
* b.p1 as entityname_property1
* b.p2 as entityname_property2
* c.id as entityname_subentity_id //<-- if this is values is null, the subentity will be null
* c.p1 as entityname_subentity_property1
* from a,b,c
