Re: ExecuteAndWaitInterceptor Issue - ThreadLocal object
I'm having a hard time understanding why refactoring your utility
class would have a serious impact on the migration time. If it's just
that you don't want to change the signature of your utility method
because it's used many other places, then create a new utility method
with the required parameters and extract the common bits. That way you
have kept your old method, created a new one and shared the common
code between them:
Before:
public static void doSomething(HttpServletRequest request) {
// Do something with the request
}
After:
public static void doSomething(HttpServletRequest request) {
// Extract params from request
doSomething(param1, param2, param3);
}
public static void doSomething(Object param1, Object param2, Object param3) {
// Do whatever you need with the params
}

As you say, the request object can be recycled by the container after
the thread has executed [1]. You can't fix this as it's up to the
container to handle this. You have to refactor your code so it's not
passing the request object around to different threads. Typically you
would extract the information you need from the request and pass the
data you nedd to the new thread instead.

You are right.
But I'm having method like

As u said, I am going to make another

Now tell me what I should write in above blank line to call my actual

Re: ExecuteAndWaitInterceptor Issue - ThreadLocal object
The other way around, something like this:
Boolean isValidUser(HttpServletRequest request) {
Map data = extractDataFromRequest(request);
isValidUser(data);
}
Boolean isValidUser(Map data) {
}
Note that you can't use the Struts 2 RequestMap either since it's
backed by the actual request object. So either you have to copy the
values in the map, or even better, extract the actual
objects/parameters the method need to do it's logic and pass them as
parameters instead.

RE: Dummy example Struts 2.0 - My Sql
Hi. Use struts-blank.war Create your action classes and required beans. You can create your ConnectionManager class that returns connection when requested. Code Action to interact with database, take connection from your connectionManager class. This is as simple as you write in simple servlet. The difference is only that you are using specialized version of servlet i.e. Action. http://javaboutique.internet.com/Web_App_Struts/ You can use above link to have brief idea. -Original Message- From: Carlos Iglesias [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 26, 2008 3:16 PM To: user@struts.apache.org Subject: Dummy example Struts 2.0 - My Sql Hello, I'm beginning wity Struts and I found the samples very useful, expecially the app struts2-showcase-2.0.11.2.war.

Try to understand my problem.
I don't wana change my method signature.
I have no problem to make another overloaded method.
But I don't want to change my original method.
You replied me with changing my original method.

Need to change over here but what?

Re: Struts2 2.0.11 problem with url and parameters
I've create a sample application with only one jsp, one action and no
user-defined interceptors. Even in this case the parameter is not being set.
These are the application main file. Please help!!I don't know what more I
can try.

Struts - indexed property problem with jdk1.5 - overloaded get/set method with same name - for Struts Team
Hello everyone;
I am using jdk1.4, struts1.0 and tomcat4.1 for my application. And I wanted
to upgrade my application to jdk1.5.
Struts1.0 had some problem with jdk1.5. I was not able to interpret two
property with the same name, one is indexed and other is not.
E.g. I have one ActionForm namely BrokerList.java.
.
String brokerName;
ArrayList brokers; // list of Broker Beans
.
And following get/set methods.
Public String getBrokerName()
.
Public void setBrokerName(String brokerName)
.
Public String getBrokerName(int index)
{
Return ( (broker)Brokers.get(i) ).getBrokerName();
}
Public String setBrokerName(int index, String brokerName)
{
( (Broker)brokers.get(i) ).setBrokerName(brokerName);
}
You can imagine the code for JSP also. User is able to enter multiple
brokers from single JSP.
Now, this code was running fine under jdk1.4. But this code doesn't run
under jdk1.5.
This gets confused when it find 2 get/set methods with the same name. But
they are actually different considering parameter index. It's overloaded
method.
I solved this issue by writing my own
org.apache.struts.util.PropertyUtils.java class to handle this situation.
(from struts.jar)
Can anybody tell me.. from what version of struts this issue is resolved???
Actually, I am on the way to upgrade my application to better version of
struts where I don't have to change in-built classes.
This issue can be better understood by Struts Team. If you don't understand
my question let me know to explain more. Your help is appreciated.
regards,
Rajil Davda

Re: Dummy example Struts 2.0 - My Sql
Thanks for answering so quickly... I'll try 2008/11/26 Rajil [EMAIL PROTECTED] Hi. Use struts-blank.war Create your action classes and required beans. You can create your ConnectionManager class that returns connection when requested. Code Action to interact with database, take connection from your connectionManager class. This is as simple as you write in simple servlet. The difference is only that you are using specialized version of servlet i.e. Action. http://javaboutique.internet.com/Web_App_Struts/ You can use above link to have brief idea. -Original Message- From: Carlos Iglesias [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 26, 2008 3:16 PM To: user@struts.apache.org Subject: Dummy example Struts 2.0 - My Sql Hello, I'm beginning wity Struts and I found the samples very useful, expecially the app struts2-showcase-2.0.11.2.war.

Re: Struts2 2.0.11 problem with url and parameters

Struts 1.3.8 : Cancel Button (and custom submit one)
Hi, I'm having a trouble setting this up: Let's imagine I have Search.do form, and clicking a link, it goes to Result.do. Then I but an html:cancel element on the jsp pages (all of them), and set something like: action path=/Welcome forward=/pages/welcome.jsp / action path=/Search type=com.something.SearchAction name=SearchForm scope=request validate=true input=/pages/search.jsp cancellable=true forward name=back path=/Welcome.do / /action action path=/Result type=com.something.ResultAction name=ResultForm scope=request validate=true input=/pages/result.jsp cancellable=true forward name=back path=/Search.do / /action I want that when a user clicks the cancel, the result will send to search, but the search will sent to the welcome page (site's home page). It all works well, too well indeed ... so I now have a problem: since the html:cancel will generate: input type=submit name=org.apache.struts.taglib.html.CANCEL value=Exit onclick=bCancel=true; / The struts framework (under RequestProcessor.processPopulate) will get this request property and set an attribute. Everything goes alright, but then my ResultAction catches the click, forwards to SearchAction but it also catches the cancel and re-forwards it to the Welcome page. Is there a way that I can remove the cancel data right before forwarding in ResultAction? So that it just make one back-forward?

On your previous example the test println isn't even being executed, so there's something else wrong, no? What if you use the url tag's action attribute w/o the .action extension? Is the link rendering properly? In general we don't use the s:a... tag for non-Ajax URLs, too--what if you use a plain HTML a... tag with the generated URL?

need to create servlet
We're working on a struts 2 application in Websphere and the plan is to serve static content via the IBM Http Server while all other requests are forwarded to the application server. We're having trouble forwarding action requests to the app server, but there's an FAQ that describes what needs to be done. http://www-01.ibm.com/support/docview.wss?rs=177context=SSEQTJdc=DB560 dc=DB520uid=swg21315589loc=en_UScs=UTF-8lang=enrss=ct177websphere The question is, how do we create a separate server context root for *.action in order to get rid of the filter mappings in the web.xml? Any hints would be appreciated... thanks, filipe

Re: need to create servlet
I am guessing its suggesting you have one context root for static content and another root for your actions and stuff. for example you might have something like for actions http://localhost/actions/login.action and for static contents http://localhost/static/login.png and in your login.action jsp you will have to refer to login.png as img src='/static/login.png'/ and in the HTTP server you set it to only intercept /static I am just guessing see if this helps
