Variable substitution at resource property file

2013-12-27 Thread Albert Kao

I like to do variable substitution at the resource property file.
I had tried this:
Resource property file:
common.name=What is the name?
page.name.01=${common.name}

Jsp file:
bean:message key=page.name.01 /

The browser displayed the desired message properly.
i.e.
What is the name? is displayed properly.
However, there was runtime error at the weblogic console:
can't parse argument number common.name
java.lang.IllegalArgumentException: can't parse argument number common.name

variable substitution in html:textarea

2014-10-30 Thread Albert Kao

How to do variable substitution in html:textarea? e.g. Java code
package util;
public interface Literals {    public static final String LAST_NAME = 
lastName;}
my.jsp
%@ page import=util.Literals %

html:textarea rows=20 cols=100 property=buffer 
value='%=Literals.LAST_NAME %'/html:textarea

I try to make lastName to appear at my.jsp but get the following 
instead:%=Literals.LAST_NAME %

replace Java scriptlets in JSP page

2014-12-29 Thread Albert Kao

The following Java scriptlet code in a Struts jsp is working fine. 
However, is it possible to change the jsp code so as to remove all the Java 
scriptlet codes? 

The .jsp code is like this:%
  HttpSession httpSession = request.getSession(true);
  MyClient myClient = (MyClient)httpSession.getAttribute(MyConst.MY_CLIENT);
%
logic:iterate id=pOwnersID name=%=MyConst.MY_CLIENT%
  property=pOwners length=%=MyConst.MY_OWNER_MAX% indexId=index
  %
    pageContext.setAttribute(requiredIndex, myClient.getRequiredIndex(index), 
PageContext.PAGE_SCOPE);
  %
  h2
    bean:message key=common.owner.label / %= myClient.getNumber(index) %
  /h2

  div
    logic:lessThan name=requiredIndex value=1
  label for='%=lastName + index%' class=required
    bean:message key=common.lastName.label /
    jsp:include page=/pages/common/required.jsp flush=true /
  /label
    /logic:lessThan
    logic:greaterEqual name=requiredIndex value=1
  label for=%=lastName + index%
    bean:message key=common.lastName.label /
  /label
    /logic:greaterEqual
    html:text styleClass=form-control
  styleId='%=lastName + index%' name=inputForm
  property='%=myForm.pOwners[+index+].lastName%' size=62
  maxlength=30 /
  /div
/logic:iterate


The java code is like this:public class Owner implements java.io.Serializable {
    private static final long serialVersionUID = 7920764268572909394L;
    private String lastName;
    private String ownershipCode;
    //...
    
    public Owner() {
    }

    // getter and setters
    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    //...
    public Integer getRequiredIndex(Integer index) {
        Integer requiredIndex = index;
        if (OWNRSHP_PARTNER.equals(ownershipCode)) {
            requiredIndex = requiredIndex - 1;
        }
        return requiredIndex;    
    }

    public String getNumber(Integer index) {
        String number = Integer.toString(index + 1);
        if (OWNRSHP_SOLE.equals(ownershipCode)) {
            number = ;

As per your instruction, modify catalina.sh:
JAVA_OPTS="$JAVA_OPTS
-Djava.protocol.handler.pkgs=org.apache.catalina.webresources
-XX:+TraceClassLoading -XX:+TraceClassUnloading"

$ catalina.sh run > my_tomcat.log 2>&1

my_tomcat.log:
[Loaded org.apache.commons.lang3.reflect.MethodUtils from
file:/home/alkao/tomee/apache-tomee-plus-7.0.3/lib/commons-lang3-3.5.jar]

Although I had done the following:
export
CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$HOME/Struts2/struts-2.5.12/lib:$CATALINA_HOME/lib:.

$ ls /home/alkao/Struts2/struts-2.5.12/lib/commons-lang3*
/home/alkao/Struts2/struts-2.5.12/lib/commons-lang3-3.6.jar

Therefore the helloworld link in index.jsp did not see the

Re: Clicking helloworld link got java.lang.NoSuchMethodError: org.apache.commons.lang3.reflect.MethodUtils.getAnnotation

2017-09-05 Thread albert kao

I tried
export
CLASSPATH=$JAVA_HOME/lib:$HOME/Struts2/struts-2.5.12/lib:$CATALINA_HOME/lib:$CLASSPATH:.

but the helloworld link in index.jsp still did not see the
/home/alkao/Struts2/struts-2.5.12/lib/commons-lang3-3.6.jar.


my_tomcat.log did not have this line any more
[Loaded org.apache.commons.lang3.reflect.MethodUtils from
file:/home/alkao/tomee/apache-tomee-plus-7.0.3/lib/commons-lang3-3.5.jar]


It had lines such as:

NullPointerException - com.opensymphony.xwork2.util.FileManager$FileRevision.needsReloading(FileManager.java:209) of "Apache Struts 2 Web Application Development" book

2017-11-11 Thread albert kao

I downloaded the source code of the book "Apache Struts 2 Web Application
Development" by Dave Newton from the
https://www.packtpub.com/books/content/support.

Chapter 2 had compile error with Apache Maven 3.5.0.
$ mvn -version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426;
2017-04-03T15:39:06-04:00)

Default locale: en_CA, platform encoding: UTF-8
OS name: "linux", version: "4.4.0-21-generic", arch: "i386", family: "unix"

To fix it, I removed just the  tag in pom.xml.
Then run mvn:
$ cd
/home/alkao/Struts2/Apache_Struts_2_Web_Application_Development/ch02/sanity
$ mvn clean package

Running wildfly-10.1.0.Final:

$ jboss-cli.sh --connect --command="deploy
/home/alkao/Struts2/Apache_Struts_2_Web_Application_Development/ch02/sanity/target/ch02-sanity-1.0.war

Running these 3 http links resulted in the same error in the web browser
below.
Please help. Thanks.

scopedModelDriven and ScopedModelDrivenInterceptor

2017-11-05 Thread albert kao

I am a Struts2 beginner.
I saw the scopedModelDriven and ScopedModelDrivenInterceptor mentioned in
chapter 14 "Migration from Struts Classic" in the "Struts 2 in  Action"
book by "Donald Brown, ...".

The Struts2 documentation said:

"public interface ScopedModelDriven
extends ModelDriven


Adds the ability to set a model, probably retrieved from a given state."

Are scopedModelDriven and ScopedModelDrivenInterceptor used for mainly
for "Migration
from Struts Classic"?
If not, please provide more explanation and source code examples.
Thanks.

When should SessionMap be used instead of Map?

2017-12-07 Thread albert kao

I am looking for an example that SessionMap should be used instead of Map.

In the Struts 2 Getting Started HTTP Session tutorial (
https://struts.apache.org/getting-started/http-session.html),
HelloWorldAction.java used
private Map userSession;

I used SessionMap to replace Map.
i.e.
private SessionMap userSession;

I got the same result after I compiled & executed the modified program, so
this is not an example to show the difference between SessionMap and Map.

Extra row appear in my jsp page after the Submit button is pressed

Triple select tag

2018-04-14 Thread albert kao

I am looking for a triple select tag component which is similar to the
s:doubleselect tag (
https://struts.apache.org/tag-developers/doubleselect-tag.html).
It renders three HTML select elements with the third one changing displayed
values depending on selected entry of second one, and the second one
changing displayed values depending on selected entry of first one.
A generic triple select tag component is desired.
If not, a slim down version is welcome.
I googled and saw s:doubleselect tag examples but did not find anything
about triple select tag.
Please suggest any websites, blogs, examples or implementation tips.
Thanks.

Re: Triple select tag

2018-04-14 Thread albert kao

Martin,

My requirement is triple select tag component implemented with Struts 2
only, without any JS function.
I am still learning how s:doubleselect tag works.
I downloaded the source code from
https://www.mkyong.com/struts2/struts-2-sdoubleselect-example/, compiled
and run it successfully.
This is still work in progress, so I am still working on an example of 3
tag-components wired together.
Please suggest any websites, blogs, examples or implementation tips.
Thanks.

Re: A book of Struts

2018-10-25 Thread albert kao

I think two books are in order:
First, S2 Basics / introduction : one single app development example.
Later, S2 Advanced: advanced topics, deep customization, Internals, Spring
integration, Javascript such as JQuery, etc.

I suggest
- moving Spring integration to the S2 Advanced book.
- adding IDE (Eclipse, ...) configuration to chapter 3.

Therefore https://github.com/lukaszlenart/struts-mini-book becomes:
1_introduction.txt
2_generate-project-with-maven.txt
3_basic-configuration.txt (with IDE (Eclipse, ...))
4_internal-di.txt
5_integration-with-tiles.txt
6_login-and-authenticate.txt
7_final-word.txt

How to display both selected key and value of s:select

2018-12-22 Thread albert kao

I want to display both selected key and value of s:select.
e.g. for the following codes, after I select
key="2", value="Canada"
and press the submit button.
Only the key "Country: 2" is displayed in the registerResult.jsp as desired.
How to make the value "Canada" to display also in the browser?

public class RegisterAction extends ActionSupport {
private String country, selectedCountry;
private ArrayList countryList;

public RegisterAction() {
countryList = new ArrayList();
countryList.add(new Country(1, "India"));
countryList.add(new Country(2, "Canada"));
countryList.add(new Country(3, "US"));
return;
}
}

public class Country {
private int countryId;
private String countryName;
public Country(int countryId, String countryName)
{
this.countryId = countryId;
this.countryName = countryName;
}
public int getCountryId() {
return countryId;
}
public void setCountryId(int countryId) {
this.countryId = countryId;
}
public String getCountryName() {
return countryName;
}
public void setCountryName(String countryName) {
this.countryName = countryName;
}
}

register.jsp








registerResult.jsp
Country: 
selectedCountry: 
CountryListAll: 
CountryListAll2: 
CountryList:

Hi Yasser,

Thanks for your useful suggestion!
It works with:
public class RegisterAction {
...
   public Country getSelectedCountryObject(String selectedCountry) {
  for (Country c : countryList) {
 if (String.valueOf(c.getCountryId()).equals(selectedCountry))
return c;
  }
  return new Country(0, "");
   }
...
}

I tried this jsp but it did not work because some s:text did not get
substituted.


">



.properties file
comp.href=https://www.mycomp.com/client.html#x1
browser.window.title=Title
common.test.button=Test



I tried to modify this jsp but then it did not compile :(.
Please help.
Thanks.

How to pass value from AbstractInterceptor to ActionSupport classes

2022-02-02 Thread albert kao

My application likes to pass value from AbstractInterceptor to two
ActionSupport classes (codes below).
When the user presses the Back button of a browser, hasValue() return true
for class Action1.
When the user presses the Back button of a browser, hasValue() return null
for class Action2.
My log show that request.setAttribute(KEY, Boolean.TRUE); //line A are
executed for class Action1 and Action2.
Where is the bug?
Is it related to type="tiles" and type="redirectAction" in struts.xml?
Please help.
Thanks.

import javax.servlet.http.HttpSession;

import org.apache.struts2.StrutsStatics;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;


public class MyInterceptor extends AbstractInterceptor {
public static final String KEY = "KEY";

@Override
public String intercept(ActionInvocation invocation) throws Exception {
HttpServletRequest httpServletRequest = (HttpServletRequest)
ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_REQUEST);

final ActionContext context = invocation.getInvocationContext();
session = context.getSession();
HttpServletRequest request = (HttpServletRequest)
context.get(StrutsStatics.HTTP_REQUEST);
HttpSession httpSession = request.getSession(true);

synchronized (httpSession) {
httpServletRequest.setAttribute(KEY, Boolean.TRUE); //line A
}
}
}


import org.apache.struts2.interceptor.ApplicationAware;
import org.apache.struts2.interceptor.RequestAware;
import org.apache.struts2.interceptor.SessionAware;
import org.apache.struts2.interceptor.ScopedModelDriven;
import com.opensymphony.xwork2.ActionSupport;

public class CoreAction extends ActionSupport implements Preparable,
SessionAware, ApplicationAware, RequestAware {

public boolean hasValue()  {
HttpServletRequest httpServletRequest = (HttpServletRequest)
ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_REQUEST);
return
Boolean.TRUE.equals(httpServletRequest.getAttribute(MyInterceptor.KEY);
}
}

public class Action1 extends CoreAction implements
ScopedModelDriven {
//...
}

public class Action2 extends CoreAction implements
ScopedModelDriven {
//...
}

Browser Back button intercept, no javascript

2022-01-25 Thread albert kao

If the user presses the Back button of a browser, my application likes to
intercept that and display a text message at the current web page.
How to do that without using javascript?

The following codes show an approach with AbstractInterceptor.
Please review whether it will work.
If yes, how to get the flag or value that the Back button of a browser was
pressed?
If not, please suggest alternatives.
Thanks.


import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.struts2.StrutsStatics;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;


public class MyInterceptor extends AbstractInterceptor {
private Map session;

@Override
public class MyInterceptor extends AbstractInterceptor {
private Map session;

@Override
public String intercept(ActionInvocation invocation) throws Exception {
   final ActionContext context = invocation.getInvocationContext();
   session = context.getSession();
   HttpServletRequest request = (HttpServletRequest);
  context.get(StrutsStatics.HTTP_REQUEST);
   HttpSession httpSession = request.getSession(true);

   synchronized (httpSession) {
   //...
   }
  }
}
