git status – displays modified files and staged files.
git commit – commits all staged files to current remote branch
git log – history of commits in the current branch
git show <commit-number> – displays commit information for a particular commit.
git show-branch – one line summary of current branch
git diff <commit-number1> <commit-number2> – difference of two commits
git mv old-file-name new-file-name – renames a file / directory, retains all commit history.
git clone <repository_name> <workspace_name> – makes a full copy of a repository

if (isEven(n)) {
return n / 2;
}
return (n * 3) + 1;
}
}


Here is sample of ant war task.

<war destfile=”myapp.war” webxml=”myapp/web.xml”>

<classes dir=”myapp/classes” />

<lib dir=”myapp/lib”>

<exclude name=”whatever you need to exclude” />

</lib>

<fileset dir=”myapp/jsp” />

<fileset dir=”myapp/html” />

</war>

In action class you can override validate() and it’s signature is:

public  ActionErrors validate(ActionMapping mapping, HttpServletRequest request)

Typically you validate presentation related information such as missing text or wrong format etc., If a validation error occurred for an input field, you can create an ActionError class  with message key (for internationalization purposes ) and the name of the input field. In the JSP you can use Struts <html:errors /> tag to display these errors.

Sometimes you need to validate business validation such as ‘check user alredy existed in the system’, these should be performed in actions’ perform(), I will post the details in my next blog.

1. Prepare you language speicific resource bundles.
2. Provide default resource bundle in struts-config.xml using message-resources
3. Include struts bean tag lib in your web.xml using taglib
4. In JSP,  include your struts bean tag lib directive
5. In JSP,  replace all hard-coded string … values with interntaionalized property keys using message property of bean tag

1. request – HttpServletRequest
2. response  – HttpServletResponse
3. Session – HttpSession
4. out – JspWriter
5. application – ServletContext
6. config – ServletConfig
7. pageContext
8. page
9. exception (available only to error pages).

Here are some examples:
<c:out value=”${pageScope.maxAttempts}” />
<c:out value=”${requestScope.maxAttempts}” />
<c:out value=”${sessionScope.maxAttempts}” />
<c:out value=”${applicationScope.maxAttempts}” />

If you try to display a value without specifying a scope, it first looks the value in the pageScope, requestScope, sessionScope and finally applicationScope. If it finds a value it displays otherwise it display ‘empty‘. Remember you won’t see null in the expression language.

Passing a constant:
<dsp:param name=”maxProducts” value=”100″ />
You can retrieve the “maxProducts” parameter in the droplet by calling request.getParamter(“maxProducts”) which returns value of 100.

Passing a bean:
<dsp:param name=”order” bean=”ShoppingCart.current” />
You can retrieve the order object by calling request.getParamter(“order”)

Passing another parameter as parameter:
<dsp:param name=”lastOrder” param=”order” />
Here the lastOrder contains the reference to order which is also parameter

In ATG you can view the content without actually sending the email, by setting dummyMode property to false of SMTPEmail component.

Here is the direct link to dummyMode property of SMTPEmail component:
http://<your_server>:<port>/dyn/admin/nucleus/atg/dynamo/service/SMTPEmail/?propertyName=dummyMode

With <dsp:getvalueof you can create a constant, param or a constant value.

Defining constant value:

<dsp:getvalueof var=”age” value=”25″ />

The equivalent in JSP:
String age = “25″;

Defining a parameter in request scope:
<dsp:getvalueof var=”age” param=”customerAge” scope=”request” />

The equivalent in JSP:
String age = request.getParameter(“customerAge”);

Defining a bean:
<dsp:getvalueof var=”employee” bean=”com.mycompany.Employee” />
The equivalent in JSP:
Employee employee = new Employee();
