Re: datetimepicker does not work
If you use the datetimepicker in date format I can preset the date value using an action and I can use the displayFormat to format the date. If I use it in type=time the time is always 12:00. I can't adjust the time or the time display format. - Original Message From: David Harland [EMAIL PROTECTED] To: user@struts.apache.org Sent: Thursday, March 29, 2007 10:21:48 PM Subject: datetimepicker does not work I am trying to use the datetimepicker but I am getting the following error 22:03:16,676 INFO [STDOUT] 22:03:16,666 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:50) at org.apache.jsp.WEB_002dINF.decorators.layout_jsp._jspx_meth_s_url_0(layout_jsp.java:151) at org.apache.jsp.WEB_002dINF.decorators.layout_jsp._jspService(layout_jsp.java:78) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:334) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672) at org.apache.catalina.core.ApplicationDispatcher.doInclude(ApplicationDispatcher.java:574) at org.apache.catalina.core.ApplicationDispatcher.include(ApplicationDispatcher.java:499) at com.opensymphony.module.sitemesh.filter.PageFilter.applyDecorator(PageFilter.java:156) at com.opensymphony.module.sitemesh.filter.PageFilter.doFilter(PageFilter.java:59) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595) 22:03:16,926 INFO [STDOUT] 22:03:16,926 ERROR [[default]] Servlet.service() for servlet default threw exception java.lang.NullPointerException at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:50) at org.apache.jsp.WEB_002dINF.decorators.layout_jsp._jspx_meth_s_url_0(layout_jsp.java:151) at org.apache.jsp.WEB_002dINF.decorators.layout_jsp._jspService(layout_jsp.java:78) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:334) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672) at
[OT] problem with displaytag column sorting in struts 1.2 web project
Hi All, In my Struts 1.2.x webapp, I am getting some Patient records from backend using my PatientManager businessObject (which uses Hibernate) to send back a populated Patients List in the request scope. (Patient is my bean). I am feeding this patientsList to Displaytag table, to show the data in a table. Here's the code snippet for my jsp containing displaytag table. http://rafb.net/p/artIJr98.html Now, I want to sort this table based on the PatientID when I click on the PatientID column. I read in the Displaytag docs http://displaytag.homeip.net/displaytag-examples-1.1/example-sorting.jsp where it mentions the following : If you want to allow the user to sort the data as it is coming back, then you need to just do two things, make sure that the data returned from your property implements the Comparable interface (if it doesn't natively - use the decorator pattern as shown a couple of examples ago), and then set the attribute sortable=true on the columns that you want to be able to sort by. Following the above suggestion, I changed my Patient class to implement Comparable interface and implemented the following compareTo method (as following) http://rafb.net/p/t0CR4Q98.html Then I re-build my app and restart it on the server, the displaytag table shows up fine. But when I click on the first column PtId, it doesn't sort the table. I just get the Http404 error page. Am I missing something ?

fired my debugger to see whether the request object would even be set (with

redirect-action configuration!
My only remaining option is to create my own redirect class that taps into
the ServletRequest object via the invocation object. Rigth now S2 is looking
very very unattractive as a web framework, because the OGNL features are not
well documented (esp in relation to struts results), and because the given

problem extending the ComposableRequestProcessor process chain
Hello Everyone, I've been working on a web application here and I've come up with a situation where I feel that extending the AuthorizeAction command class would be a quality solution to a challenge I am facing. When I complete this I would be willing to contribute this back for others to use. Here is some necessary background on what I am trying to do. Sorry for the length on this: The application I am working on has complex requirements for role-based authorization checks. When the check fails and the user is not authorized, we do not want to just throw an exception or report an error. We want to direct the user to a page with instructions on how they can become authorized. Many of the actions will have different requirements, and therefore different checks and different pages with different instructions. I came up with what I thought was an elegant and cheerfully easy way to do this, but it has not been so easy as I thought. In the struts-config.xml file I define the action, including its roles, and I include a forward for where the instructions are located for users who fail the authorization checks. Here is an example of one of these actions: action path=/orders/create type=mypkg.CreateOrderAction roles=createOrders forward name=unauthorized path=/help/ordersHowTo.do redirect=true/ /action I then wrote a class to replace the default AuthorizeAction class which is part of struts. It contains the complex logic which checks to see if the user has the createOrders role or not. If they do, it would return false to allow the chain to continue. If not, it would retrieve the ForwardConfig for unauthorized, add it to the context, and then return true to break what I was hoping was the process-action sub-chain, and then the process-view chain which executes next would retrieve the ForwardConfig from the context and then send the user there. Unfortunately this does not work the way I was anticipating :-( What happens is that the chain stops completely at that point. This is where I get into trouble and I am hoping someone can point me in the right direction. Here is what the default servlet processing chain looks like for me: chain name=servlet-standard !-- Establish exception handling filter -- command className=org.apache.struts.chain.commands.ExceptionCatcher catalogName=struts exceptionCommand=servlet-exception/ lookup catalogName=struts name=process-action optional=false/ lookup catalogName=struts name=process-view optional=false/ /chain Is there a way that I can terminate the process-action chain early but still have it execute the process-view chain after? I will greatly appreciate any help or suggestions that you can offer. Best Regards, Aaron Titus - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: resume after login feature
It turns out that ${ServletRequest.requestURI } is the correct OGNL
expression. Of course you need to have a getServletRequest method in your
action superclass, which means all of your actions for your application that
requires a login will have to implement that method or subclass from a class
that does.
Dale, the parse param is set to true by default so I didn't have to set
it.
The second part requires redirecting to the origurl location after a
successful login. This the OGNL expression I have so far, but it's not
working yet. I'll post again once i fix it.
param name=location${#ServletRequest.parameter[origurl] == null ?
Welcome.do : #ServletRequest.parameter[origurl]}/param

As a proof of concept, I did (more or less) the
following, just as a sanity check:
- IRolesAware
Actions requiring login implement this (contains
get/setRoles) and are given a roles param.../ in
their struts config. Not a perfect solution, but for
demonstration purposes it's fine.
- RolesInterceptor
If the invoked action impls IRolesAware it checks for
login, if not logged in it puts the requested URL
(with query string) into session and returns the login
page's global result.
- LoginAction
If login succeeds puts the original url from session
into a property originalUrl and returns a SUCCESS
result, which is a result for LoginAction that looks
like:
result type=redirect${originalUrl}/result
...also set loggedIn indicator and removes
originalUrl.
So there is nothing special going on; you check for a
login in the interceptor (and can check for specific
roles against the roles the action expects, but that's
not really part of the discussion). Not logged in,
save URL and go to login. (Optionally if not right
role, go to wherever you need to based on whatever
criteria you want.) Logged in and/or have the role,
process the invocation normally.
It just seems cleaner; what am I missing?

Re: resume after login feature
Thanks Dave for that sanity check. The only difference between your
implementation and mine is that you put the originalUrl in a session whereas
I store it away in the client. They're both the same 'cleanlinest' i think.
Dale, I was considering ACEGI / SecurityFilter, but I still had to make sure
that this feature was *possible* before deciding to use Struts. If the
framework can't handle login-resume easily, then it can't be a good
framework. Fortunately everything works fine.

role, go to wherever you need to based on whatever
criteria you want.) Logged in and/or have the role,
process the invocation normally.
It just seems cleaner; what am I missing?

Re: [s2] Struts Dependency Injection and EJB3 - support ? or how can i Do it?
I coded this today, just used the field instead of a setter method. Your
pseudo code was very helpful, thanks :-)
Maybe the following snippet is useful for someone with the same problem.
Should I post this on the wiki as well? I am not sure if it is a good
solution - but it works for me.
Can someone please tell me if it is ok to call this every time an action needs
the service, or would it be better to cache the service somewhere in
application scope? I am quite new to this whole ejb thing.

EJBInterceptor.java
public class EJBInterceptor extends AbstractInterceptor implements Interceptor
{
public String intercept(ActionInvocation actionInvocation) throws
Exception {
Object action = actionInvocation.getAction();
for (Field f : action.getClass().getDeclaredFields()) {
if (f.isAnnotationPresent(EJB.class)) {
f.setAccessible(true);
String serviceName = f.getType().getName();
Object service = null;
try {
InitialContext ic = new InitialContext();
service = ic.lookup(serviceName);
} catch (Exception ex) {
System.out.println(Error: +ex.getMessage());
}
f.set(action, f.getType().cast(service));
break;

return actionInvocation.invoke();
}

From here you would need to ensure that the interceptor is applied to
the actions that need ejb's.

Re: resume after login feature

The only difference between your implementation and
mine is that you put the originalUrl in a session
whereas I store it away in the client. They're both
the same 'cleanlinest' i think.
If you say so; it sure seemed like yours was a lot of
work, and frankly I'd rather role and/or login-aware
actions implemented something specific to that
functionality, for a couple of reasons.
So when I compare these chunks:
param name=location
${#parameters['origurl'] == null ?
'Welcome.do' : #parameters['origurl']}
/param
s:form action=Login.do validate=true
s:if test=${param.origurl ne null}
s:hidden name=origurl
value=${param.origurl}/
/s:if
etc. to:
action name=login class=resume.LoginAction
result name=input
/WEB-INF/jsp/resume/login.jsp
/result
result name=success type=redirect
${originalUrl}
/result
/action
action name=page1 class=resume.Page1Action
param name=rolesrole1, role2/param
result/WEB-INF/jsp/resume/page1.jsp/result
/action
... and a ~50-line interceptor I can't help but like
it. If you chain the login action result it's even
easier and more encapsulated, but so far I prefer the
login url appears for login rather than holding on to
the original request URL; I'm still undecided.
Dale, I was considering ACEGI / SecurityFilter, but
I still had to make sure that this feature was
*possible* before deciding to use Struts.
I think S2 handles this trivially, but if something
else handled it better, then what would it matter?
Regarding OGNL documentation, bear in mind that OGNL
is a *completely* separate project. The basics are
mostly covered on the Wiki, if you need more
information than that then the OGNL reference
documentation would be the reasonable place to look.

Hello Dave:
in terms of work, yours and mine are about the same complexity. However, I
prefer my solution because it doesn't require sessions for guest users, and
this is a good measure for performance. To each his own. :)
I think S2 handles this trivially, but if something
else handled it better, then what would it matter?
Now I see that S3 handles it trivially, but how would a beginner to S2/OGNL
know without implementing it for himself? Whether or not somethign else
handles it better is irrelevant. The question was whether S2 is flexible
enough for the tasks that I need done.
Regarding OGNL documentation, bear in mind that OGNL
is a *completely* separate project. The basics are
mostly covered on the Wiki, if you need more
information than that then the OGNL reference
documentation would be the reasonable place to look.
I'm aware, the wiki makes it pretty clear. On the other hand, the overlap
between Struts and OGNL (i.e. what variables are available in the stack for
OGNL expressions etc) is NOT documented well, and that documentation belongs
squarely in the Struts wikis. For example, the Struts wiki does not explain
what the 'request' stack value is (I thought it was the session request
object, but it is not), and some important stack values are not listed.
(such as 'parameters'). Last but not least, it is not obvious that the OGNL
expressions need to be enclosed in ${} when used in the struts config file.
(Is this even true? I don't know since it's not documented! It certainly
isn't documented so in the OGNL documentation).
This is why I asked about wiki authorship permissions.
Anyways, are you a developer for Struts Dave? You've been very helpful,
thanks.
