Subject: template and I18N
Hi all,
I've just started to use Struts and I have some questions:
1. How can I use the I18N features in the template tags?
In my template.jsp I've got the following tag:
titletemplate:get name='title'//title
In the page using this teplate the following:
template:put name='title' content='Kalkulation' direct='true'/
I'd like to replace the German text 'Kalkulation' with its
key e.g. 'app.title.calculation' Is there a nice way to do this?
2. How can I use use the I18N features in Struts directly
in Java Scriplets?
Sometimes I need the translated texts in scriplets. What is
the best way to access them?
Now I am using this aproach:
%
MessageResources resources =
(MessageResources) pageContext.getAttribute(
Action.MESSAGES_KEY, PageContext.APPLICATION_SCOPE);
Locale locale =
(Locale) pageContext.getAttribute(
Action.LOCALE_KEY, PageContext.SESSION_SCOPE);
if (null == locale) {
locale = request.getLocale();
}
String myText = resources.getMessage(locale, app.the.text,key);
%
Thanks for an answer

Constants.TOKEN_KEY value proposed change (doesn't work with javascript!!)
Hi,
I use the token_key for transaction support.
But the value of the TOKEN_KEY = org.apache.struts.taglib.html.TOKEN
This is a very odd value to have as a hidden input field on your form.
Which is generated by the FormTag:
input type=hidden name=org.apache.struts.taglib.html.TOKEN
value=
Because you want to use that hidden field in some javascript:
function submitNextpage(themakey)
{
document.nextpage.org.apache.struts.taglib.html.TOKEN.value=themakey;
document.nextpage.submit();
}
You get a javascript error!
Because javascript sees all names between points as an object.
Please change the TOKEN_KEY value in TOKEN_KEY or something like that!!

you could do:

and then have a general.exception in youre resouce bundle:

Please respond

Hi Darren,
we're using VAJ 3.5.2 Enterprise with Tomcat and Struts. First we tried to
run Struts 1.0b1 with Tomcat Test Env 3.1 but unfortunately Struts does not
work with Tomcat 3.1's XML-Parser. If you want you can make a XML
(javax.xml.*) SQL (javax.sql.*) package and put it into Tomcats ./lib
directory and add it to VAJ's classpath. But if you use Tomcat 3.2.1,
struts works out of the box - but not that comfortable as the Tomcat Test
Env does, e.g. you can't debug JSP and Servlet Code anymore :(((
I did a hack (in Tomcats WebReaderXML.java to enable "jspPageCompiler"
again) and added "com.ibm.ivj.tomcat.IJVJavaCompiler" again to re-enable
in-workspace JSP and Servlet Debugging.
Running Tomcat 3.2.1 in VAJ 3.5.x
~~~
In short:
0.) Prerequisites:
* latest jakarta-servlet-api _source_
* tomcat 3.2.1 binary distribution (includes ./src already)
* Tomcat 3.1 Test Environment from www.ibm.com/vadd (to get
"com.ibm.ivj.tomcat.IVJJavaCompiler.java")
* struts 1.0b1 source distribution
1.) Install Tomcat 3.1 Test Environment look into
/path/to/vaj35/ide/features/com.ibm.ivj.tomcat/... to find
IVJJavaCompiler.java
2.) Start VAJ, do _not_ "Add feature Apache Test Env 3.1"!!!
3.) Create new Package, e.g. Apache_Tomcat_321
4.) Import all source from jakarta-servlet-api (do _not_ use servlet-api
from VAJ or other precompiled javax.servlet.* - classes; they _must_ be
compiled within VAJ Workspace to enable debugging of your own servlets and
JSPs) into your Project
5.) import following -- compiled classes (not source!) - from jasper.jar
and webserver.jar (both in tomcat-3.2.1/lib/)
jasper: all .class
webserver: org.apache.tomcat.logging.Logger,
org.apache.tomcat.logging.LogHelper, org.apache.tomcat.util.SimplePool
If VAJ still complains about missing classes (you see this in "All
Problems" - Tab) import compiled .class files from ./lib/*.jar until VAJ is
happy.
6.) create two classes: StartTomcat StopTomcat (code is the same for
both!)
public class StartTomcat {
/**
* StartTomcat constructor comment.
*/
public StartTomcat() {
super();
}
/**
* Starts the application.
* @param args an array of command-line arguments
*/
public static void main(java.lang.String[] args) {
// Insert code to start the application here.
try {
Class aClass = Class.forName("org.apache.tomcat.startup.Tomcat");
java.lang.reflect.Method method = null;
Class[] argsClass = new Class[] { String[].class };
method = aClass.getMethod("main", argsClass);
Object object = null;
Object[] arguments = new Object[] { args };
method.invoke(object, arguments);
} catch (Exception e) {
System.out.println("Exception occured: " + e.getMessage());
e.printStackTrace();
}
}
}
Right click StartTomcat in VAJ and goto "Properties-Classpath": have
follwing files and dirs in classpath:
.;
..\Apache_Struts;
..\IBM IDE Utility class libraries;
..\JSP Page Compile Generated Code;
.\;
.\conf\;
.\src\;
.\lib\jaxp.jar;

And in Properties-Programm have no arguments for StartTomcat and "-stop"
for StopTomcat. Also have "tomcat.home=." in "(java)Properties window"

Re: Data Connection Pool, solution?
there should be another attribute in the datasource like this: testSql="select * from test" and GenericConnection has a setTestSql(String) method and that test method is executed right before the connections is given to the request in getConnection() When it fails it closed and tries another one (or opens another one) So anyone can decide there own test method/sql statement, because i don't think there is a common one. Only some rules must be set: Must the testSQL string return a result set and must it have one result if not it is the same as failing? This would be a nice addition to struts 1.0!

Tomcat question
Hi, One tomcat question for this list (i know there are some tomcat developers here) Why can't i find changes.html or something like that for the tomcat versions? You got now a 3.1.x branch (doesn't seem to be in development anymore) 3.2.x branch (still development 3.2.2 beta 1 as latest mile stonde) 3.3.x branch (the latest in 3.x) And you got 4.0 I know the differences between 3.x (servlet 2.2 / jsp 1.1) and 4.x (servlet 2.3 / jsp 1.2) But why all those 3.x branches and why are there even 2 in development?

BeanMessage Tag proposal
Hi,
When setting the args (arg0,arg1,arg2,arg3,arg4)
you must do this:
bean:message key="foo.foo.foo" arg0="foo1" arg1="foo2"/
But i think it is very rare that you know exactly at design time of the jsp
what value there must be. Because if you do then why not set it directly in
the message it self?
So it is almost any time a runtime expression.
But then i must do things like this:
bean:define id="argstring1" value="totalautotheft"/
bean:define id="argstring2" value="autotheft"/
bean:define id="insurance" name="carinsurance" scope="session"
type="nl.topicus.thema.DynamicForm"/
bean:message key="prompt.advise.wacasco" arg0="%=
insurance.getProperty(argstring1).toString() %" arg1="%=
insurance.getProperty(argstring2).toString() %"/
I must define
bean:define id="argstring1" value="totalautotheft"/
because i can't do this:
bean:message arg0="%= insurance.getProperty("totalautotheft").toString()
%"
I find this a bug of the Tomcat parser if you ask me. Because if he sees
that it is a reqexpr (%=)
then it should first find the % before looking at the closing "!!
Because if these problems i wanted to find a solution
Why is is not possible that i get the Object[] from a name/property???
Then the BeanTag is also not limmited to only 5 args
My example for the above one:
app:message key="prompt.advise.wacasco" (arg)name="insurance"
(arg)property="wacascoObjects"/
and the insurance.getWacascoObjects() does return the Object[] for that
string:

But when i also specify the name/property then i want the value to be filled in when name/property seems to be null! so not: // Retrieve the required property value Object value = this.value; if (value == null) value = RequestUtils.lookup(pageContext, name, property, scope); but: // Retrieve the required property value Object value = null; if(name != null) value = RequestUtils.lookup(pageContext, name, property, scope); if (value == null) value = this.value; johan
Re: DefineTag.value question (proposal)
so not: // Retrieve the required property value Object value = this.value; This will return null if you did not specify a "value" attribute, so the effect is the same as your desired result -- setting the new bean based on the name/property combination. This is not my desired result because i want it to be a default value. It should not ignore the name and property attributes if they are specified. // Retrieve the required property value Object value = null; if(name != null) value = RequestUtils.lookup(pageContext, name, property, scope); if (value == null) value = this.value; This would reverse the priority of lookups, and make the string you specified for the "value" essentially a default if the specified property returns null. That is different from the current behavior, and different from what is documented, but makes a certain kind of sense. But the behaviour is not changed for all the application build today because None in using a name, value combo because at this time that combo doesn't make any sense because it doesn't do a thing. What do people think about changing this? You got my vote! johan
Tomcat (servlet2.2 spec question)
Hi all, Is it really true that everything that is in the webapp context must be served by the webapp? Here our discussion with the support of ServletExec: -- Hi, Who has made that specification?? Because it it stupid. Apache/IIS must do the things they are goed at and that is serving static content. ServletExec/Tomcat/JRun to name a few must do things they are good at and that is serving jsp/servlets And saying that i must keep the images, static html ect ect in an other place is an enormous maintenance and development problem. I want everything to getter what belongs to each other. Apache with tomcat works perfectly the way i want. Je specify a Alias in apache: Alias /myprogram c:/tomcat/webapps/myprogram And in the conf files of apache that is included in the httpd.conf of apache you say this; JkMount /*.jsp ajp13 JkMount /*.do ajp13 That is the way it should work Only the JSP's and the .do (struts framework redirects) are handled by tomcat the rest by tomcat. And if i want to do the same with ServletExec then i must put the jsp ect in the webapps/myprogram and the rest in /myprogramstatic? And i must switch in both constantly pointing to each other? What happens if webapps/myprogram changes in webapps/myprogram2 ? Everything in /myprogramstatic my also change? Because i can't use relative url's anymore?? Not to mention that in development you must do the same but there i use Tomcat as http server and app server. And for every project i must have 2 context in tomcat. And they must be exactly the way be configured as the deployment server!

RE: Business Object Bean Persistence Strategies
Hi,
Because i want Database Objects to control them self completely (like Enity
beans)
I must have a way to get Transaction support and make sure that in on thread
the same connection is being used. For example:
class Person
{
private String name;
private Country country;
public static Person findByPrimaryKey(int i)
{
Connection connection = datasource.getConnection();
// Select
Person person = new Person();
person.setName(rs.getString(1));
person.setCountry(Countr.findByPrimaryKey(rs.getInt(2)));
connection.close();
}
}
class Country
{
privatge String name
public static Country findByPrimaryKey(int i)
{
// Now another connection is being taken from the datasource
// if max == 2 then another call in this thread to the datasource
// will present a deadlock!!
Connection connection = datasource.getConnection();
// Select
Country country = new Country ();
/// Filling
connection.close()
return country;
}
}
So i want a datasource to return a connection that is already attached to
the
current thread.
Same goes for updating or inserting of data for example a new Person with a
new Country object that i want to insert into the database
person clas:
{
public void store()
{
Connection connection = datasource.getConnection();
// Before storing the country id the country must first be stored:
country.store();
// if all goes well:
// Store the person (insert into person values(?,?,?,?)
ps.setInt(2,country.getPrimaryKey());
// if not all goes well the connection.rollback must be called.
// but one problem the country was stored under a different connection
// so it will not be rolledback!!
}
}
country class
{
public void store()
{
// Another connection is taken so if it goes bad then you can't
rollback
// everything!!
Connection connection = datasource.getConnection();
// Store the country (insert into person values(?,?,?,?)
}
}
To get around those above problems i am building a Transaction class.
This wraps around the Datasource
it has a static method:
public static Transaction startTransaction() // Only starts a transaction
onces for the current thread.
and the Transaction object has methods:
public Connection getConnection()
public void setRollbackOnly() // Error occured somewhere so only a rollback
allowed.
public int getStatus() // Must rollback, Healty.
public void rollback()
public void commit() // Can only do this if mustRollback == false else throw
exception
public void stopTransaction()
In the above examples i don't do
datasource.getConnection()
but
Transaction transaction = Transaction.startTransaction();
Connection connection = transaction.getConnection();
// Cannot call connection.close() , connection.rollback(),
connection.commit() directly!!!
transaction.stopTransaction();
If anyone is interrested or has some comments i am happy to hear it.

Subject: Business Object Bean Persistence Strategies
What strategies or patterns do people use to manage persistence
of business
object data in a Struts application when there is no EJB layer
and there is
a desire to keep the business objects as independent of the web
portion of
the application as possible? Do you use the Struts DataSource and pass
either it or a Connection as a parameter to bean methods that take
responsibility for managing persistence? Do you follow the J2EE
blueprint
and create separate Data Access Objects to support persistence? Are you
using an open-source framework to manage persistence? This seems like a
common problem, but I haven't seen much talk about common solutions.
Mike
Datasource proposal
Using another one is very difficult because how the properties are set.
(I want to use the org.apache.struts.sql one but this one has many more options
and totally different method names to set the properties (like url ect)
And also the open en close methods aren't called automaticly.
So i propose a new interface:
interface StrutsDataSource extends DataSource
{
open()
close()
setProperty(String str,String)
}
those property can be everything: url,driver class ect ect
exactly the things that can be specified in the struts-config.xml
Then the implementor must map the string "url" to it's own method.
Then struts must use this and handle this a bit different then now (it must
detect that the object is a StrutsDataSource and then not trying to set the properties
through PropertyUtil (or BeanUtil) but calling the setProperty method.

Re: Admin actions
This would be very nice but remember that the struts-config.xml sits inside the war file And you don't have any control over it then.

I almost have a graphical interface to the admin actions done, but in order to make it truly useful, I think automatic update of the config file needs to happen on unload (or even before). Is there a technical reason preventing this from happening, or is it just implemented this way for now? If it turns out to be an omission, I'll implement that as well to support the admin application. One other thing: I noticed that with Tomcat it's possible to get a list of webapps defined for the engine. It appears that this is not a J2EE standard. Is that correct? If so, the admin classes and config file changes would need to happen on a per-webapp basis. I'd prefer to walkthrough the webapps and have a "struts-admin.war" file to do all of the administration. I just don't think that will be feasible in a portable manner. Any opinions or advice? Thanks. -- Dan Miser
Re: Class reloading?
Tomcat 3.1 and 3.2 seem to reliably detect cases where the servlet class you are actually calling has been changed, but they do not always seem to catch the fact that other classes have been changed. Tomcat 4.0 uses a different mechanism that reliably catches *all* changes to classes found in WEB-INF/classes. But that is not needed.

bean:parameter question

If the bean:parameter is used and the request parameter (the name
specified)
isn't found i don't want an exeception but i want the bean parameter to use
a
empty string ("").
So that after that all bean:write prints that empty string if the paramter
wasn't there.
I want this behaviour because if a specifiek paramater is specified i want
the title to include this parameter. But this is not a requiredment! If it
isn't
specified then noting must be added to the title (the jsp does after that a
logic:present and shows something if it is there.
Can't a simple property be added to bean:parameter?
like defaultvalue=""
Then i can specify that that value must be used when the parameter isn't
there.

Re: GenericDataSource usage in non-servlet classes
You must have a reference to the servlet or servletcontext somehow.
You could do something like this (you should store the servlet not the session):
protected void process(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
HttpSession session= request.getSession(true);
SessionHandler.storeCurrentSession(session);
super.process(request, response);
SessionHandler.removeCurrentSession();
}
And the SessionHandler is this:
public class SessionHandler
{
private static java.util.HashMap _hmSessions = new java.util.HashMap();
public static HttpSession getCurrentSession()
{
return (HttpSession)_hmSessions.get(Thread.currentThread().getName());
}
public static void removeCurrentSession()
{
_hmSessions.remove(Thread.currentThread().getName());
}
public static void storeCurrentSession(HttpSession session)
{
_hmSessions.put(Thread.currentThread().getName(), session);
}
}
Then you can always call SessionHandler.getCurrentSession()
As long as you are in the same thread as the current request, which is very likely

Jsp Compilation question. (Want to load Jsp's from my own location=database)
Hi, My JSP files are stored in a database because it should be possible to change the jsp pages on the fly without deploying a complete new war file and/or shutting down the application server. And it must be possible to upload those jsp pages through our maintenance web pages of our application. The problem is how to develop a standaard way so that the (re)compilation of those jsp's works over different application servers. In tomcat i can override the jspCompilerPlugin param of the JspServlet to get what i want i believe!? init-param param-namejspCompilerPlugin/param-name param-valueorg.apache.jasper.compiler.JikesJavaCompiler/param-value /init-param But this is i believe Tomcat specifiek. So what i can do is make my own JspServlet and replace the default JspServlet of the application servlet by defining in my web.xml my own mapping and servlet: servlet-mapping servlet-name jsp /servlet-name url-pattern *.jsp /url-pattern /servlet-mapping and a servlet: servlet servlet-name jsp /servlet-name servlet-class my.package.MyJspServlet /servlet-class /servlet In tomcat 3.1 this works: Context log: path="/postbank" Removing duplicate servlet jsp Wrapper(my.package.MyJspServlet) Context log: path="/postbank" Removing duplicate *.jsp - Wrapper(jsp org.apache.jasper.runtime.JspServlet) So it seems that by default the JspServlet is attached to that context and when specified another one it removes that one and uses the specified one. Is this standard behaviour? But after that i come accross a problem: How can i parse and complile the Jsp to a Servlet??? Because then i need an application specifiek item. In tomcat i believe Jasper? So to make a large question short: If i want to load the Jsp pages from my own location how to implement the rest so that it works with more then one specifiek App Server?

Re: Datasource serializeable (Was: 1.0 status of MessageBundle and non-serializable application resources)
Why depend on this? Because it is the standard approach mandated for J2EE applications, to access all sorts of resources (including data sources). But i don't want to get dependend on a J2EE server. (it's already hard to find a JSP/Servlet ISP on the internet) But the problem is that i am writing a Web app at this time. And i want it to run on both environments. (A normal JSP/servlet container and a J2EE container) Because i want it to run on both environments i must just the lowest common denominator (do i say this right?) And that is using a Datasource. Why not make the GenericDatabaseSource also serializeable with externalizeable? I don't think just making it Externalizable (without also declaring Serializable) will meet the requirements of the app servers. Does anyone know? The interface Serializable is a super interface of Externalizable (it extends)! The only difference is that Externalizeable gives you complete control (i almost use Externalizable for everyting) then in the writeExternal(ObjectOutputStream) you close all the connections and save all the data (properties/maxcount/readOnly/ect/ect) when the readExternal is called you read all those properties and the connections will be created with the next call to getConnection() You could do the same (with only slightly more pain) by creating custom readObject() / writeObject() methods for serialization. I'd be willing to accept a patch that does this -- I'm not going to have time to do it in the short term. Yes that is my idee. Only the logWriter is a problem then. However, there's a bigger issue here. The reason an app server wants to serialize these things is to distribute them -- and there is no guarantee that the database URL, username, password etc. are valid from every single server you might distribute them to. You are also increasing the number of total connections that will be established to your database -- perhaps without knowing it -- even if the connection parameters are valid. I will check this out. thx for the info. It seems to me that data sources belong to an individual server instance. Not always why? If the server where it's getting distruted do have everywhere the same connections Then the database driver/ url and password should work over every server johan

Re: GenericDataSource Enhancement
Except that the javax.sql.DataSource API still includes this method signature, so we need to do something. I guess it would probably be better to return a "not implemented" exception of some sort, then just return a "regular" connection like it does now. Yes or just a normal connection that the user auto closes when he calls close, so won't be pooled or anything. What should be done is testing the isClosed() method before given the Connection to the request. If the database closes the connection will the connection.isClosed() return a boolean true then? My experience has been that this is not sufficient. You don't find out that the driver connection got closed until you try to submit an SQL statement for execution -- what we need to be able to configure is a very low-overhead SQL call that can be tried before returning the connection to the user. What about a extra rollback() call right before given it back to the request? Or is the driver/connection smart enough that the rollback doesn't do anything (because nothing happend) and it doesn't send it to the server? johan
Re: HTML tag library
Do it before the 1.0 release. Because after that is will be much more difficult. johan - Original Message - From: "Ted Husted" [EMAIL PROTECTED] To: "Struts List" [EMAIL PROTECTED] Sent: Monday, January 08, 2001 12:04 PM Subject: HTML tag library Did we decide to rename the FORM tag library as the HTML tag library in a 1.0 timeframe? I agree it makes sense, the library has outgrown just forms, but it seems to break my existing late-model JSPs. Worked on the third, now not. We've been assuring people for several weeks that the code-breaking changes were complete. Or, is there a top-level way we can get the JSP's to use the HTML lib instead without editing them all? The change is not mentioned in the release notes, and I didn't see anything here; at first I thought it was a new library that would hold additional non-form tags. If we have some other non-form tags in mind (image, et cetera), I would suggest we leave the form library as it is, and introduce a new HTML library (since the form library is big enough), where both libraries would support the :html, :base, :link tags, and tags on an interim basis. I would also consider moving the bean:message, logic:interate, and logic:redirect tags to a HTML library. Of course, this becomes a discussion of procedural versus functional cohesion, and reasonable people can disagree. In any event, seperate HTML and Form libraries does seem to have higher cohesion to me, since some people might want to use the HTML tags without the rest of it. Incidentally, I note the JAR has jumped in size a bit this week. Was that the addition of the bean property options, or something else?
Re: GenericDataSource Enhancement
I suppose besides adding datasources with different logins, we could also add entirely different DBMS's?, on entirely different servers? Yes that is what the current solution already offers. So the getConnection(String user, String pasword) doesn't have to be implemented, Because if you really need this make another datasource under some kind of key. What should be done is testing the isClosed() method before given the Connection to the request. If the database closes the connection will the connection.isClosed() return a boolean true then? Johan
RE: Template layout file with an include (bean or jsp) to a jsp with a form. (there are many tomcat developer here also i believe)
Hi,
I thought i shall be smart, i developed my own:
IncludeServletResponse that implements HttpServletResponse)
That one routes everything to the base servlet response of the pagecontext
except the outputstream ones:
The getOutputStream() returns not the default one of the first Response
but my own implementation but now the bug of Tomcat??:
IncludeResponse iResponse = new
IncludeResponse((HttpServletResponse)pageContext.getResponse());
RequestDispatcher rd=
pageContext.getServletContext().getRequestDispatcher(_sPage);
rd.forward(pageContext.getRequest(), iResponse);
iResponse is my own implentation.
The RequestDispatcher interface wants only a ServletResponse (and a
ServletRequest)
It compiles fine so how is it possible that the RequestDispatcher throws a
ClassCastException inside itself?
What kind of ServletResponse does it wants?

Subject: Template layout file with an include (bean or jsp) to a jsp
with a form.
Hi,
I will ask the basic question first so that you don't have to
read the whole
email:
So is there no way to use the same request over 2 or more jsp
files that are
nested in
each other?
Now my test case:
I have a template jsp file that has all the layout of my site.
in the right left corner will al the dynamic data.
like this:
// tag libs includes
form:html locale="true"
head
titlebean:message key="index.title"//title
/head
body bgcolor="#fce8a0" topmargin="0" leftmargin="0"
table width="100%" border="0" height="123" cellpadding="0"
cellspacing="0"
bgcolor="#0066ff"
tr
td
// standard layout of my site
// jadajadajadajada
/td
// The include logic.
logic:present name="%= JSP_INCLUDE_KEY %" scope="request"
bean:include id="subpage" name="%=
(String)request.getAttribute(Constants.JSP_INCLUDE_KEY) %"/
%= subpage %
/logic:present
logic:notPresent name="%= Constants.JSP_INCLUDE_KEY %"
scope="request"
bean:include id="subpage" name="/index.jsp"/
%= subpage %
/logic:notPresent
/tr
/table
/body
/form:html
This template file is always the ActionForward that i return as the next
page to see
after this action, something in the perform method of a Action:
request.setAttribute(Constants.JSP_INCLUDE_KEY,
mapping.findForward("pensioen3a").getPath());
return mapping.findForward("template");
The nicest thing about this is that if i want to change something
of my site
i only have to edit
one file and every page/view is changed also like the logon page or the
pages with the forms.
But now my problem.
An Action is mostly triggerd by the subpage (where the form is in).
That Action is testing the input (some validation) if that goes wrong that
a ACtionError is made and is attached to the request.
But when i forward it (to the same page) i forward it to the
template again
and that
template includes the page with the form.
But the include generates another request for that subpage so my
ActionErrors object
and other objects that i stored in the request aren't there!!
I also do this in te validate() of a Form:
String fromPage = request.getParameter("frompage");
mapping.setInput(mapping.findForward("template").getPath());
request.setAttribute(Constants.JSP_INCLUDE_KEY,
mapping.findForward(fromPage).getPath());
So that when there are errors returned it knows that the input is the
template and the
include is the same page it come's from.
But this also doesn't work.
I can't be the only one with this problem.
Are nobody else using subpages where the form/inputs are in an another one
that is the standard layout page?
I thought to be smart and made my own include tag:
public int doStartTag() throws JspException
{
try
{
RequestDispatcher rd=
pageContext.getServletContext().getRequestDispatcher(_sPage);
rd.forward(pageContext.getRequest(),
pageContext.getResponse());
} catch(Exception e)
{
throw new JspException(e.getMessage());
}
return SKIP_BODY;
}
But the problem is then that the subpage (the _sPage string) is displayed
first, above
the main page instead of in the main page. Why is this? Because
when i walk
through the code
then i see the main page that writes to the output and then the
subpage and
then the main
page again. I think this has something to do with flushing ect.
But if i flush first (right above the RequestDispatcher line i do this:
pageContext.getOut().flush();
Then i get the main page on to

Re: Form errors
Use my ErrorTag attached.
I copied almost from ErrorsTag but only generated it for the property that was set.
I hope this or another one just like it will be in the default struts lib.
(they can use mine attached)
The current implementation isn't used very much on the internet. Users want
to see what the did wrong and where to fix it.
And that's why the ErrorTag is much handier then the ErrorsTag.
If multiply errors are set for one property it will be comma seperated.
johan
I probably missed this in the documentation, but if I want to pull out the
error message for a specific field, how would I do it? Let's say I have a
username which was left blank and I create a new ActionError :
errors.add("username",new ActionError("error.username.required"));
Now, in my .jsp, rather than having all the errors displayed with
form:errors/, I want to put the
error.username.required error right next to the username field:
form:text property="username" size="16" maxlength="16"/ nbsp;
form:errors username-only
I don't want it to use errors.header or errors.footer either in this case.
Is that possible?
Thanks.

(Property)MessageResources proposed changes.
Hi,
( i am trying to subscribe to STRUTS-DEV but i don't get a confirmation message so i
post it first here)
When the new MessageResources class (and its sub) where introduced my app didn't
work anymore because of the changed behaviour in loading resouces.
I have 2 fixes that i have attached here:
First is the MessageResources.localeKey(Locale) method that is needed by both
PropertyMessageResources that i send in.
this:
protected String localeKey(Locale locale) {
if (locale == null)
return ("");
else if (locale.equals(defaultLocale))
return ("");
else
return (locale.toString());
}
is changed to this:
protected String localeKey(Locale locale) {
if (locale == null)
return ("");
else
return (locale.toString());
}
Because when it is the default locale or not that doesn't matter. First it must try to
load the right resources for the default locale.
For example if the default locale is nl_NL then i want it to try to load:
xxx.nl_NL.properties or xxx.nl.properties before it tries to load xxx.properties.
Because maybe now my webapp is on a system there the default locale is nl_NL
but maybe it's also getting deployed on a system with the default locale en_US.
Then suddenly the struts load the wrong properties file for the locale,
(What must be the xxx.properties file? English or Dutch?)
ResourceBundle it self does also try to load the nl_NL first it doesn't look
if the given locale is the default one or not.
PropertyMessageResources.getMessage(Locale,String) changes:
this piece of code:
// As a last resort, try the default Locale
localeKey = localeKey(defaultLocale);
messageKey = messageKey(localeKey, key);
loadLocale(localeKey);
synchronized (messages)
{
message = (String) messages.get(messageKey);
if (message != null)
{
if (addIt)
messages.put(originalKey, message);
return (message);
}
}
is changed to this:
// try the default Locale if current locale isn't default
if(locale != defaultLocale)
{
localeKey = localeKey(defaultLocale);
messageKey = messageKey(localeKey, key);
loadLocale(localeKey);
synchronized (messages)
{
message = (String) messages.get(messageKey);
if (message != null)
{
if (addIt)
messages.put(originalKey, message);
return (message);
}
}
}
// last resort: try loading de base
localeKey = "";
messageKey = messageKey(localeKey, key);
loadLocale(localeKey);
synchronized (messages)
{
message = (String) messages.get(messageKey);
if (message != null)
{
if (addIt)
messages.put(originalKey, message);
return (message);
}
}
So i my last resort isn't trying to get it with the defaultLocale
I test it first (maybe equals should be used in tead of == )
so that the loading and the synchronized lock isn't invane.
After that and still the message isn't returned i go to my last resort
and that is loading the base (xxx.properties)
But i thought why implement the exact same behaviour of the ResouceBundle?
So i made my own class.
Here are the 2 methods:
public String getMessage(java.util.Locale locale, String key) {
if(locale == null) locale = defaultLocale;
String localeKey = localeKey(locale);
String messageKey = messageKey(localeKey, key);
String message = null;
// first try to load a previous stored resource.
synchronized (messages) {
message = (String) messages.get(messageKey);
}
// if there was no previous stored resource.
if(message == null) {
// try loading the resources
loadMessages(locale);
// try getting it again.
synchronized (messages) {
message = (String) messages.get(messageKey);
}
}
// If still null.
if(message == null) {
// Return an appropriate error indication
if (returnNull) return (null);
else return ("???" + messageKey(locale, key) + "???");
}
return message;
}
protected void loadMessages(Locale locale) {
String localeKey = localeKey(locale);
// Have we already attempted to load messages for this locale?
synchronized (locales) {
if (locales.get(localeKey) != null) return;
locales.put(localeKey, localeKey);
}
ResourceBundle bundle =
java.util.ResourceBundle.getBundle(config,locale,this.getClass().getClassLoader());
if(bundle != null) {
synchronized (messages) {
Enumeration names = bundle.getKeys();
while (names.hasMoreElements()) {
String key = (String) names.nextElement();
messages.put(messageKey(localeKey, key), bundle.getObject(key));
}
}
}
}
I use the resoucebundle class to get the properties.
This has the following advantages:
1 Not having to implement and maintain the complete reading in code.
2 support for not only resource property files but also resource class files!!
3 No double keys for all the resouces when given locale = nl_NL and the properties
file = xx_nl.properties
explain 3:
Locale = nl_NL
propertie file = xxx._nl.properties
first messages aren't found for that locale key.

Does struts have a Dynamic Form.
Hi, Let's say i want to make something so that i can edit database tables. I don't want to write for every database table that must be editiable a special jsp page. For every database table i have a Java Mapping Object. Not all Columns are editable, only the specified ones. DynamicForm form = new DynamicForm() form.setDatabaseObject(javaMappingObject); form.setEditableColumns(String[]) When the user presses submit i can validate the form in the perfom() and get the updated database object back so that i can update the database. does struts have something like this?

vote for a Action.USER_KEY constant.
In many jsp/servlets apps there is somekind of user object. It would be nice to have a default constant for this. And with taht in mind it would also be usefull that i can define in the web.xml or struts_config.xml that is want to load that object as User object (using the Action.USER_KEY) whenever a Session object is created. Or is this possible already? Because now i must in every jsp page check if that object is there because i user can bookmark a page in the middle of my app. So defining something like this would be handy: servlet init-objects param scope=session keyorg.apache.struts.action.Action.USER_KEY/key objectcom.xxx.xxx.User/object /param param scope=application keycom.xxx.xxx..DATABASE_KEY/key objectcom.xxx.xxx.DatabaseHandler/object /param /init-objects /servlet Or defining an object for every request.

Where is the form:error property=xxxxx tag?
Hi,
I have attached 2 html files as an example;
Errors.html is the default one that i get when using: form:errors/ tag in a jsp file.
and a
Error.html is the one that i want to have.
form:errors/ has some drawbacks like:
1 The layout of the input screen suddenly changes.
2 You must link the error text and the right input field with each other. (the user
must, visually)
In the second approace the error text is right besides the input field.
You do store errors under it's property name:
errors.add("fromAddress", new ActionError("error.fromAddress.required"));
so with that in mind there must be somthing to get one specifiek error very easy
without much code.
something like this: (registration.jsp example from adress section)
tr
th align="right"
bean:message key="prompt.fromAddress"/
/th
td align="left"
form:text property="fromAddress" size="50"/
/td
/tr
becomes this:
tr
th align="right"
bean:message key="prompt.fromAddress"/
/th
td align="left"
form:text property="fromAddress" size="50"/
font color=#ffform:error property="fromAddress"//font
/td
/tr
The form:error property="fromAddress"/ returns the same error string that belowns
to that property or "" if none set.
Before i code this myself i thought let's ask it before i do something twice.

Why are there 2 ForwardTag classes (and someothers)?
logic and in taglib have both classes that are almost exactly the same.
one difference: In logic package exceptions are first added as an attribute of
pageContext:
pageContext.setAttribute(Action.EXCEPTION_KEY, e, PageContext.REQUEST_SCOPE);
and then the exception is thrown.
throw new JspException(messages.getMessage("forward.forward", name, e.toString()));
in taglib only the exception is thrown.
Why is this?

getting Locale strings in a ActionForm
hi,
I want to use a html select with a few options.
Those options are specified in resourcebundles for different locales.
I have a CustomForm class:
class CustomForm
{
public String[] getOptionValues()
{
return new String[]{"resourcekey1","resourcekey2"}
}
public String[] getOptionLabels()
{
String[] asValues = getOptionValues();
String[] asLabels = new String[_asValues .length];
org.apache.struts.util.MessageResources messages = servlet.getResources();
for (int i = 0; i asWaarden.length; i++)
{
asLabels[i] = messages.getMessage(asValues [i]);
}
return asLabels;
}
}
i use this in a JSP page:
struts:select property="optionvalue"
struts:options property="optionValues" labelProperty="optionLabels"/
/struts:select
This goes well for the default locale, but if i let the user changes it's locale then
everything changes with it except the options in the select!!
This is because the messages.getMessage(asValues [i]); call the
message.getMessage(Locale locale ,)
with the locale as a null property.
And when the MessageResources class gets a null locale it uses the default locale of
the server.
So when the server has a locale nl_NL and the users selects a different one: en_US
everything else that uses struts:message / changes but not the options.
Can i get the handle to the current session object in a ActionForm bean?
Why not set the Session object also so that we have much more power/data at our hands?

request)
{
// Is there a form bean associated with this mapping?
String attribute = mapping.getAttribute();
if (attribute == null)
return (null);
// Look up the existing form bean, if any
if (debug = 1)
