Database connectivity
Dear sir(s), I tried to connect to the database at 192.168.1.1:/crm through by configuring struts-config.xml. this is actualy my local system. I am using postgresql as my database back end. it is running on the default port of postgresql 5432. I am using pgjdbc.jar(for org.postgrsql.Driver). I had configured eclipse to use this driver and also copied pgjdbc.jar,commons-dbcp-1.2.1.jar,commopns-dbutils.jar etc. but when i executed the application(I am using tomcat) it shows an error null pointer exception in the LogonAction.java how this can be overcame? Thanking You, vineesh [EMAIL PROTECTED]
RE: I suspect this is a bad idea...so what's a better one?
Craig,
Thanks for the idea.
Only problem I see with this that I usually make my real actions some
flavor of a DispatchAction, usually a MappingDispatchAction.
So to keep that type of functionality, it appears that I'd have to
replicate a lot of the Struts dispatch/reflection logic inside of my
abstract Action subclass. Calling super.execute() gets me that, but that
is precisely what this concept seems to try to avoid. :-/
-Original Message-
:snip:
A useful design pattern for something like this is to create
a common subclass for your actions that does the
setup/teardown work in the
execute() method, and then delegates to the action-specific
work in some other method. For your scenario, it might look
like this:
public abstract class BaseAction extends Action {
public ActionForward execute(...) throws Exception {
Persistence persistence =
ActionHelper.getPersistenceObject(request);
try {
ActionForward forward = delegate(mapping,
form, request, response, persistence);
} finally {
persistence.release)(;
}
}
protected abstract ActionForward
delegate(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response, Persistence persistence)
throws Exception;
}
Then, your real business logic is implemented in a delegate()
method that is passed in for you, and you never have to
remember to allocate and release the persistence object.
public class RealAction extends BaseAction {
protected ActionForward delegate(...) {
... use the persistence object as needed ...
}
}
This is pretty close to what you've got now ... the key
difference is that it uses a local variable instead of an
instance variable to avoid sharing problems. Also, because
of the finally clause, it also ensures that the persistence
object is cleaned up, even if the
delegate() method throws an exception.

OptionsCollectionTag with ActionForm and a collection attribute
I am just studying the basic things about Struts, and have some trouble getting selectTag and optionsCollectionTag work as I would expect. Intention is to have two properties in a form: allChoices, that is a collection holding all possible choices for the select tag, and selectedChoicesCollection, that contains the currently selected ones. Each choice is modelled by a class Choice, that contains two attributes, id for identifying the selection and name, which is displaed to the user. SelectedChoicesCollection contains only the values of the Choices (as having it contain Choice objects did not seem to work at all). I have to actions, SimpleGetAction and SimpleSaveAction. User starts by calling a URL which maps to SimpleGetAction. This action populates the form object and moves on to the JSP page. This part works out as I excpect, and the correct choice(s) is highlighted. When user submits the form, SimpleSaveAction gets called - except that BeanUtils.populate throws an exception before action gets it's turn: 12:34:46,268 INFO [STDOUT] DEBUG [org.apache.struts.util.RequestUtils][1799] Get module name for path /SaveSimpleTest.do 12:34:46,268 INFO [STDOUT] DEBUG [org.apache.struts.util.RequestUtils][1821] Module name found: default 12:34:46,268 INFO [STDOUT] DEBUG [org.apache.struts.action.RequestProcessor][225] Processing a 'POST' for path '/SaveSimpleTest' 12:34:46,268 INFO [STDOUT] DEBUG [org.apache.struts.util.RequestUtils][764] Looking for ActionForm bean instance in scope 'request' under attribute key 'simp eForm' 12:34:46,268 INFO [STDOUT] DEBUG [org.apache.struts.util.RequestUtils][839] Creating new ActionForm instance of type 'jannen.form.SimpleTestForm' 12:34:46,268 INFO [STDOUT] DEBUG [org.apache.struts.util.RequestUtils][844] -- jannen.form.SimpleTestForm selectedChoicesArray: selectedChoicesCollection: 3] 12:34:46,308 INFO [STDOUT] DEBUG [org.apache.struts.action.RequestProcessor][372] Storing ActionForm bean instance in scope 'request' under attribute key 'si pleForm' 12:34:46,388 INFO [STDOUT] DEBUG [org.apache.struts.action.RequestProcessor][813] Populating bean properties from this request 12:34:46,388 ERROR [Engine] StandardWrapperValve[action]: Servlet.service() for servlet action threw exception javax.servlet.ServletException: BeanUtils.populate at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:256) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643) at org.jboss.web.tomcat.security.JBossSecurityMgrRealm.invoke(JBossSecurityMgrRealm.java:220) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:641) at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:246) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:641) at org.jboss.web.tomcat.tc4.statistics.ContainerStatsValve.invoke(ContainerStatsValve.java:76) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:641) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2417) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:171) at

I have a performance issue in this that the combo boxes on this JSP wherein data comes from the database are taking very long time to populate. I think the issue is with writing JDBC statements in the JSP directly. I need inputs on this. Is the presence of JDBC statements affecting the performance of this JSP ? Should I write a separate bean with all my queries in it and use this in the JSP? Regds Aditya
RE: mapping an action twice with Xdoclet
Hi David
Sorry... I haven't explained myself well... Xdoclet writes the two
action in config file, but the problem comes with
@struts.action-forward and @struts.action-exception, as Xdoclet writes
the forward and the exception in each action.
if I write something like that:
* @struts.action

* parameter=load
* validate=false

*path=/submitAdminUsersForm
*parameter=submit
*
* @struts.action-forward
* name=success
* path=/loadAdminUsersForm.do
*
*/
public class AdminUsersAction extends Action {

it generates this xml file

RE: I suspect this is a bad idea...so what's a better one?
Joe, you could move your business logic to a service layer which
also leverages the Command pattern. You could have a base command
which did something similar as Craig has outlined.
public abstract class BaseCommand {
public void execute() throws Exception {
try {
// set up transaction
doExecute();
} catch (Exception e) {
// abort transaction
} finally {
// clean up transaction
}
}
// implement actual work here.
public abstract void doExecute() throws Exception;
}
then
public class MyCommand extends BaseCommand {
public void doExecute() throws exception {
// put business logic here
}
}
in your action's execute method (be it DispatchAction, MappingDispatchAction, etc...)
public ActionForward execute(...) throws Exception {
ActionForward forward = // get appropriate forward
Command command = // get the appropriate command and initialize it
command.execute();
return forward;
}
You might also check out the Spring framework. It allows you to declaratively demarcate
transaction boundries (similar to EJB).

Struts and Websphere security - best practice
I have a struts app that I am deploying in WebSphere 5.1. Everything works fine, no issues with WAS per se. Now I am trying to activate security and I am running into some bumps in the road. The security setup is simple: With global security enabled on WAS, authenticating against ldap (openldap repository in the test environment), I only need to designate in my web.xml a security-constraint indicating which resources are protected, and a login-config which indicates the name of the login page to use. The login page must call a WAS servlet called j_security_check. When an unauthenticated user tries to navigate to a protected resource, WAS will redirect the user to the login page designated in the login-config tag, and process the login from there. If anyone is reading this, you probably know all this already. From the looks of things, using the above scheme, I do not need to define a path in struts-config.xml to the login page, as I would normally do. With index.jsp as my welcome page, which contains only a redirection to the entry point path in my struts-config.xml, I expect WAS to kick in and redirect any user trying to access sessionStart.do first to the designated login page before allowing access to the struts action. My security-contraint in fact protects *.do.

Localization within Tiles
Hi all, (sorry for a bit longer message) I have encountered an interesting problem. In my struts application I am using tiles and localization through ApplicationResources.properties files. In my jsp page I have messages written as: bean:message key=label.messageText/ however, sometimes I would like to refer to a value defined in tiles. Such as: tiles:getAsString name=messageText/ In the tilesDefinition.xml file I have e.g.: --snip-- put name=messageText value=Hello/ --snip-- What I would like to do is to combine these 2 approaches and have localized messageText without needing to rewrite it in tiles def. file. Because this is the case in the tiles-documentation example supplied with tiles: definition. put name=messageText value=Bye/ /definition and in another language in tiles def. _de: definition. put name=messageText value=Tshus/ /definition But this implies a lot of (imho) unnecessary typing. The solution I've had in mind would go something like this: definition put name=messageText value=label.messageText/ /definition and in the jsp there would be: bean:message key=tiles:getAsString name=messageText/ That way I would have all the localized strings in .properties files only. But unfortunately such nesting is not possible. I have tried using scripting variables (as I have been facing this kind of nesting problems more often) but did not succeed. I would appreciate any comments how to solve this issue. Thanks. Regards, Radek _ Ing. Radek Vclavk ICS Department - webmaster ZeNTIVA a.s.

is this a struts bug?
hihi,
i have a jsp with the following:
c:forEach var=i begin=0 end=5
html-el:text name=MyObj property=foo[${i}].bar/
/c:forEach
in MyObj i have these methods:
public Collection getFoo() {
return foo;
}
public Bar getFoo(int i) {
while(i = foo.size()) {
((ArrayList)foo).add(new Bar());
}
return (Bar)((ArrayList)foo).get(i);
}
when i request for the jsp, it calls the first getFoo() method. should
it not call the second getFoo(int) method instead, since the jsp is
using jstl to provide an index parameter?
the weird part is when i take out the getFoo() method and recompile,
then the jsp calls getFoo(int) correctly.
why is the behavior like this? is this a bug?
(when it calls the first getFoo() method i get an indexOutOfBounds
exception because my foo collection has nothing in it... i want the
collection size to be driven by the jsp page)
thanks in advance,
woodchuck

Re: Struts and Websphere security - best practice
On Mon, 9 Aug 2004 10:35:14 -0400, Tom McCobb [EMAIL PROTECTED] wrote: I have a struts app that I am deploying in WebSphere 5.1. Everything works fine, no issues with WAS per se. Now I am trying to activate security and I am running into some bumps in the road. The security setup is simple: With global security enabled on WAS, authenticating against ldap (openldap repository in the test environment), I only need to designate in my web.xml a security-constraint indicating which resources are protected, and a login-config which indicates the name of the login page to use. The login page must call a WAS servlet called j_security_check. When an unauthenticated user tries to navigate to a protected resource, WAS will redirect the user to the login page designated in the login-config tag, and process the login from there. If anyone is reading this, you probably know all this already. Yep :-). From the looks of things, using the above scheme, I do not need to define a path in struts-config.xml to the login page, as I would normally do. That is correct. With index.jsp as my welcome page, which contains only a redirection to the entry point path in my struts-config.xml, I expect WAS to kick in and redirect any user trying to access sessionStart.do first to the designated login page before allowing access to the struts action. My security-contraint in fact protects *.do. This is how IBM sets up its admin console for WAS, in fact, although they incorporate everything into a form bean/action class, and I instead detour out of struts just for the login process. I am not having much diffculty with authentication in this manner, although authorization is another matter. One thing to double check is that your welcome page really does do a *redirect* to sessionStart.do, rather than a jsp:forward. The latter will not kick in the container managed security, because they are only applied on the URL that is originally requested from the client (which will be the one for the welcome page in this scenario). Using *.do is the correct URL pattern for all the rest of the requests, since that is the URL that the form submit actually uses. However, it won't help you deal with fine-grained authorization (i.e. different people can execute different actions). For that, you can either define separate mappings in your security constraints (with different user roles required for access), or use the role attribute on the action element to ask Struts to check for the presence of that role. So my question is, what is the best way to do this? Should I protected the static index.jsp instead of any call to the action servlet, or both, or all resources (I have read through and tried to implement the IBM example of using SSL for unathenticated access to the login.jsp, and non-secure authenticated access to everything else)?

I have a performance issue in this that the combo boxes on this JSP wherein data comes from the database are taking very long time to populate. I think the issue is with writing JDBC statements in the JSP directly. I need inputs on this. Is the presence of JDBC statements affecting the performance of this JSP ?

RE: Localization within Tiles
You can do something like this : In your tiled definition : --snip-- put name=messageText value=message.text/ --snip-- In your jsp: Do something like tiles:getAsString name=messageText/ titlebean:message name=messageText//title So in the title... a value corresponding to the value of messageText which is message.text will be fetched in the resources and will be replaced. So in short in the tiles definition instead of the value of the messageText (Hello) put a key (message.text) of the resources for that particular message and later get it in the usual way as shown.

What I really want is this: input type=checkbox name=item[0].selectedAnswers value=0 input type=checkbox name=item[0].selectedAnswers value=1 input type=checkbox name=item[0].selectedAnswers value=2 input type=checkbox name=item[0].selectedAnswers value=3 input type=checkbox name=item[0].selectedAnswers value=4 input type=checkbox name=item[1].selectedAnswers value=0 input type=checkbox name=item[1].selectedAnswers value=1 input type=checkbox name=item[1].selectedAnswers value=2 input type=checkbox name=item[1].selectedAnswers value=3 input type=checkbox name=item[1].selectedAnswers value=4 Can I do this with the multi-box tag? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

One scenario might be to handle NestedException, You might override execute(Exception ex, ExceptionConfig config, ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) method of ExceptionHandler to show error messages for all the exceptiosn. * Here's an advice from jakarta: A common use of ExceptionHandlers is to configure one for java.lang.Exception so it's called for any exception and log the exception to some data store.. Is it really a nice strategy??? Well Sure, first a local ExceptionHandler is invoked if found, otherwise, the global ExceptionHandlers are searched, if not, the Exception's superclass are searched in a similar fashion. So, declaring a handler for java.lang.Exception, will always be there for you as a default handler for any type of Exception, if you haven't defined a specific handler for that particular exception.

Re: I suspect this is a bad idea...so what's a better one?

Comands are really a good Solution for acting on business logic. See the
common-chain framework also. It offers command and chains to access the
business logic in different manner.

Joe, you could move your business logic to a service layer which
also leverages the Command pattern. You could have a base command
which did something similar as Craig has outlined.
public abstract class BaseCommand {
public void execute() throws Exception {
try {
// set up transaction
doExecute();
} catch (Exception e) {
// abort transaction
} finally {
// clean up transaction
}
}
// implement actual work here.
public abstract void doExecute() throws Exception;
}
then
public class MyCommand extends BaseCommand {
public void doExecute() throws exception {
// put business logic here
}
}
in your action's execute method (be it DispatchAction, MappingDispatchAction,
etc...)
public ActionForward execute(...) throws Exception {
ActionForward forward = // get appropriate forward
Command command = // get the appropriate command and initialize it
command.execute();
return forward;
}
You might also check out the Spring framework. It allows you to declaratively demarcate
transaction boundries (similar to EJB).

Craig,
Thanks for the idea.
Only problem I see with this that I usually make my real actions some
flavor of a DispatchAction, usually a MappingDispatchAction.
So to keep that type of functionality, it appears that I'd have to
replicate a lot of the Struts dispatch/reflection logic inside of my
abstract Action subclass. Calling super.execute() gets me that, but that
is precisely what this concept seems to try to avoid. :-/
-Original Message-
:snip:
A useful design pattern for something like this is to create
a common subclass for your actions that does the
setup/teardown work in the
execute() method, and then delegates to the action-specific
work in some other method. For your scenario, it might look
like this:
public abstract class BaseAction extends Action {
public ActionForward execute(...) throws Exception {
Persistence persistence =
ActionHelper.getPersistenceObject(request);
try {
ActionForward forward = delegate(mapping,
form, request, response, persistence);
} finally {
persistence.release)(;
}
}
protected abstract ActionForward
delegate(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response, Persistence persistence)
throws Exception;
}
Then, your real business logic is implemented in a delegate()
method that is passed in for you, and you never have to
remember to allocate and release the persistence object.
public class RealAction extends BaseAction {
protected ActionForward delegate(...) {
... use the persistence object as needed ...
}
}
This is pretty close to what you've got now ... the key
difference is that it uses a local variable instead of an
instance variable to avoid sharing problems. Also, because
of the finally clause, it also ensures that the persistence
object is cleaned up, even if the
delegate() method throws an exception.

clone of ActionForm to DomainObject
hi all:
I get this problem for some week, It is very troubler.
Now I use xdoclet to generate the ActionForm form the DomainObject.
I want to implement some method convert it.
(1) Method 1 : only one ActionForm to changed to DomainForm
eg:
code
class SimpleActionForm () extends ActionForm
{
public getName ()
{...}
public setName ()
{...}
}
class Simple ()
{
public getName ()
{...}
public setName ()
{...}
}
/code
This is easy to use BeanUtils.copyProperties(target, o);to do it
(2) Method 2 : one-to-anotherone or one-to-many or one-to-anotherone-many . ?
how to deal with this kind of ActionForm to changed?
eg:
code
class OneActionForm () extends ActionForm
{
public getName ()
{...}
public setName ()
{...}
public getAnotherActionForm ()
{...}
public setAnotherActionForm ()
{...}
}
class AnotherActionForm() extends ActionForm
{
public getName ()
{...}
public setName ()
{...}
}
/code
code
class One ()
{
public getName ()
{...}
public setName ()
{...}
public getAnother ()
{...}
public setAnother ()
{...}
}
class Another()
{
public getName ()
{...}
public setName ()
{...}
}
/code
I think I can regiest a Convertor to ConvertUtils,
to dynamic changed the ActionForm Object to DomainObject.
do it?
--
how to do it? pls give some advice or some opensouce to solve,
thanks.
Regards,
charlse
EL question
I have a logic:iterate tag that is creating HTML table rows. I want to set a bgcolor variable to use for each row. If the row is even numbered, I want to use color A. If the row is odd numbered, I want to use color B. What tags should I use? What EL operation should I use to determine if the current iterator index is even or odd? I was thinking along the lines of: begin logic:iterate set bg color var to 'A' if iterator index is odd, set bg color to 'B' render the table row end logic:iterate I would appreciate some advice on how to implement this neatly, using the EL tags or JSTL tags. I'm trying to graduate from using scriptlets for stuff like this. Thanks, Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
