struts needs to map url requests to FilterDispatcher
your WEB-INF/web.xml should have filter configured and mapped as:
  <filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    <init-param>
       <param-name>actionPackages</param-name>
       <param-value>your.action.package</param-value>
    </init-param>
    <init-param>
       <param-name>templateDir</param-name>
       <param-value>template</param-value>
    </init-param>      
    <init-param>
       <param-name>theme</param-name>
       <param-value>simple</param-value>
    </init-param>  
    <init-param>
       <param-name>org.apache.catalina.jsp_file</param-name>
       <param-value>index.jsp</param-value>
    </init-param>
  </filter>

  <filter-mapping>
    <filter-name>struts</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

ive used OpenEJB with TC
then again you could deploy your EAR to a true EJB3 container with a J2EE-AppServer such as GF, WL or AMSServer..even resin would handle EJBs

Hi,

I have made a struts form:
<s:form action="addProduct" method="POST" >
Name nl<s:textfield name="productNameNl" />
price: <s:textfield name="productPrice" value=""/>
</s:form>

and the mapped actionclassmethod addProduct with:

public String addProduct(){
Product p = new Product(productNameNl, productPrice);
ProductDA.getInstance().addProduct(p);
return SUCCESS;
}

public void setProductNameNl(String productNameNl) {
this.productNameNl = productNameNl;
}

public String getProductNameNl() {
return productNameNl;
}

public void setProductPrice(double productPrice) {
this.productPrice = productPrice;
}

public double getProductPrice() {
return productPrice;
}



When I run my jsp with that form, everything goes well when I enter for
example 3 or 5 in the pricebox.

But when I enter 0 (not the letter O, but zero), 0,0 or a letter i get
the error message:

/-- Encapsulated exception ------------\

java.lang.NoSuchMethodException: setProductPrice([Ljava.lang.String;)



Why doesn't it recognize a zero as a double, but as a string?

I think with a validation xml the problem with the letters will be
solved?



Any help would be appreciated!



Thx,

Sandy

Well everyone has an opinion so here mine:

I want to unit test my Struts actions in the full Struts context which
includes the interceptor stack and validation. This way I know my actions
and results are configured correctly since I test them. I also know my
declarative validations are working correctly. I use junit and I really
don't want or have time to have to learn another test tool for integration
testing.

So to do this type of testing I wrote a StrutsTestContext class to run my
actions.
For full info see:
http://glindholm.wordpress.com/2008/06/30/unit-testing-struts-2-actions/

I don't use Spring so this class would need to be tweaked for Spring but you
are welcome to use this as a starting point.

This gives me a lot of flexibility for testing, sometimes I test against an
actual database (with hibernate) and sometimes I mock the services that the
actions use.

Hi!

I am wondering, why setters for cmd and id fields @ my Person action (see
below) is called twice. For example, when browser requests
/person-aaa-bbb?dum=ccc , this gets stdout-ed :

example.Person@(protected)
setCmd ]aaa[
setId ]bbb[
setCmd ]aaa[
setDum ]ccc[
setId ]bbb[
execute

I know setter is just a setter, but this thing is really annoying me :) -
definately this kind of behaviour is undesirable. Any thoughts?
