It shouldn't matter, but the browser might be deciding something wonky based
on the fact that that url doesn't end .css...you could either add css as an
action extension or maybe use urlrewrite to make a .css url actually result
in your .action request.
Tried it both ways -one as an action class, one as a css. The headers
didnt' vary enormously (or relevantly).
public void getConfiguredStylesheet() throws IOException, Exception {
Shouldn't all action methods return String? What's the action mapping
associated with this?
-should-, but all this class is doing is writing to the
HttpServletResponse object.
resp.getWriter().write(sb.toString());
resp.getWriter().flush();
resp.getWriter().close();
The appropriate return value for actions that generate their own output is
null. This is rarely the best solution, though, as there's more to the http
protocol than the content of the response. You're returning no header
information.
That's not the case actually - the http headers are there (curl -i shows
them).
curl http://localhost:8080/congo/public/getConfiguredStylesheet.action
try curl -i to see the header info. Compare that output to a curl -i request
for a .css file delivered by your web app through more conventional methods.
resp.setContentType(text/css);
I believe that since you're generating the response yourself this has no
effect.
If you want to return a stream, there is a stream result type that'll help
you out:
http://struts.apache.org/2.2.1/docs/stream-result.html
It's not -really- a stream. I perhaps used the wrong name there. See
other comments in this thread (or comments taht'll be there in a few

Re: Bizarre sporadic problem with streaming a stylesheet. [Solved?]
So this got weird. I tried everything. Rewrote the method, changed the responses, put debugging all over - nada. I could reproduce the problem by rapid-firing ^R at the browser, and the home would render with the stylesheet about half the time. It was interesting seeing it flip back and forth. My JSP's had two stylesheet lines in them, like this: LINK REL=StyleSheet href=getStylesheet.action type=text/css LINK REL=StyleSheet href=getConfiguredStylesheet.action type=text/css The first one would have loaded the 'default' style, with the configured oversion overriding / updating the sheet as necessary. I removed the first one. And it all started working perfectly. I don't know if it's a bug in the first action class (which HAD been working perfectly on it's own until I added the second line), or what - but I'm running now. How.

Bizarre sporadic problem with streaming a stylesheet.
Help me obi-wan struts-geeks. This one is puzzling me.
I need to 'stream' a stylesheet out to the browser. Due to the app,
that stylesheet is sort of generated on the fly from the database, so I
can't just point the browser at a static file.
In the document, I have:
head
meta http-equiv=Content-Type content=text/html; charset=UTF-8
LINK REL=StyleSheet href=getConfiguredStylesheet.action
type=text/css
/head
Here's the method mapped to this (note this is at the moment reading
from a file off the filesystem, not from the db - but even the comment
in the StringBuffer doesn't show up)
public void getConfiguredStylesheet() throws IOException, Exception {
logger.info(Fetching configured stylesheet...);
sessionData = ActionContext.getContext().getSession();
// Open up the .css file specified in the event
try {
InputStream is =
sc.getResourceAsStream(/public/web-emphasis.css);
logger.debug(inputstream for stylesheet should not be null. It is:
+ is);
BufferedReader br = new BufferedReader(new
InputStreamReader(is));
logger.debug(Setting up sb with basic stylesheet info...);
StringBuffer sb = new StringBuffer(/* Read via CSSFetcher from
web-emphasis.css */\n);
String s ;
int counter=0;
while ((s = br.readLine()) != null) {
counter++;
sb.append(s + \n);
}
logger.debug(Stringbuffer counted + counter + lines, and is +
sb.length() + bytes long.);
is.close();
logger.debug(Writing it to the response...);
resp.getWriter().write(sb.toString());
resp.getWriter().flush();
resp.getWriter().close();
} catch (Exception e) {
logger.error(e);
logger.error(e.getMessage());
e.printStackTrace();
throw e;
}
}
Here's the problem.
The stylesheet shows up in the browser - only about 4 times out of 5.
Every 3rd, 4th, 5th, sometimes 6th webhit, there's no stylesheet. The
log, however, shows that the stylesheet went out - no matter whether
it's available in the stylesheet viewer on the browser or not, the log
always says:
2010-09-20 23:30:20,743 INFO [CSSFetcher] Fetching configured stylesheet...
2010-09-20 23:30:20,743 DEBUG [CSSFetcher] inputstream for stylesheet
should not be null. It is: java.io.bufferedinputstr...@23b35955
2010-09-20 23:30:20,744 DEBUG [CSSFetcher] Setting up sb with basic

lines, and is 4889 bytes long.
2010-09-20 23:30:20,745 DEBUG [CSSFetcher] Writing it to the response...
My guess is there's some weird interraction with timing with how the
stylesheet is being loaded and when the browser is expecting it to be
completed. I can't for the life of me figure out what it is. The
flush() and close() lines in the method were added to attempt to 'finish
up' the connection, but they made no difference.

Session variables in s:radio buttons - preselection and formatting?
I have a twofold question.
The first is I have a session variable called 'sendto' which contains a
string ('registrant','none', or 'everyone'). When the page with the
radio buttons is rendered, I want to preselect based on whatever the
value in the session hash for 'sendto' is set to.
Code:
div style=float: right; width: 150px;
bNotifications/bhr
Send email to:br
s:radio
list=#{'none':'None','registrant':'This
Registrant','everyone':'Everyone on this invoice'}
value=#{sendto} name=sendto /
/div
I woudl have thought the value=#{sendto} would have done that, but it
doesn't. I've checked and the session key 'sendto' does have the value
'registrant' in it.
Secondly - These render on a straight line, one right after another.
I'd like line breaks br between each radio button. Is this possible?
Thanks!

Simple redirect, OFF-site.
Hey folks, I was just searching the archives (lots of requests for
redirects, but not one similar to what I need).
I'm implementing a Paypal payment gateway, which requires an HTTP call to
get a URL from a remote webservice, then I need to redirect the user to
that URL.
I have the URL (that part is all coded), now all I need to do is redirect
the users browser to http://something.paypal.com/someparameter.
In scriptlet mode, I'd just do:
%
String redirectURL = http://something.paypal.com/someparameterB;;
response.sendRedirect(redirectURL);
%
To do this in the struts-way I'd need to make my action responseaware and
feed data into it. I'd rather just do something like
String target = http://somewhere.paypal.com/;;
return redirect;
then in struts.xml
result name=redirect type=redirect-action
/WEB-INF/jsp/Redirect.jsp/
and have my Redirect.jsp have a ${target} in it
How to do this? In short, how do I have a struts action redirect the
users browser to an arbitrary (off-site) URL?

My struts.xml has... !DOCTYPE struts PUBLIC -//Apache Software Foundation//DTD Struts Configuration 2.0//EN http://struts.apache.org/dtds/struts-2.0.dtd; struts include file=struts-editevent.xml package name=CONGO extends=struts-default interceptors [blah blah blah] /interceptors (more actions) /package /struts The 'struts-editevent.xml' has: action name=coconut/viewEditEvent method=load class=com.stonekeep.congo.coconut.EditEvent interceptor-ref name=mystack / result name=success/WEB-INF/jsp/coconut/EditEventForm.jsp/result result name=login type=redirect-actioncoconut/showloginpage/result /action action name=coconut/postEditEvent method=update class=com.stonekeep.congo.coconut.EditEvent interceptor-ref name=mystack / result name=success/WEB-INF/jsp/coconut/Maintenance.jsp/result result name=input/WEB-INF/jsp/coconut/EditEventForm.jsp/result result name=login type=redirect-actioncoconut/showloginpage/result /action A basic block of actions.

Referring to Properties object via OGNL?

I'm storing the Properties object up into the ApplicationMap (heck it could be in the SessionMap, I'm easy), but i can't seem to switch JSP behaviour based on information in the Properties map. I'm wondering if this is because Properties isn't exactly a HashMap, so the #attr.mapname.somekey isn't working.

ApplicationAware not triggering setApplication? Or, how best to reference a Connection pool?
Hi folks - i'm trying to write an interceptor in struts2 that has access
to the ApplicationMap in the application context.
My understanding is that the webwork API for ApplicationAware means that
the interceptor will have it's setApplication(Map applicationData);
triggered when the interceptor is run, thereby giving me access to the
applicationcontext.
Problem is, it isn't :)
Here's the relevant parts...
public class DBInterceptor extends AbstractInterceptor implements
ApplicationAware {
...
@Override
public void setApplication(Map arg0) {
logger.info(Receiving applicationMap...);
this.applicationMap = arg0;
}
That logger is never triggered, 'applicationMap' is always null.
My struts.xml is:
interceptors
interceptor name=dbsetup
class=com.stonekeep.congo.interceptors.DBInterceptor /
interceptor-stack name=mystack
interceptor-ref name=dbsetup /
interceptor-ref name=defaultStack /
/interceptor-stack
/interceptors
(The goal here is to store a c3p0 connection pool object in the
application context, so that I can get a connection from it on every hit
- I assume this is the proper way to do this?)
Thanks, any help would be appreciated...

ApplicationAware should be used with Actions not with interceptors, to
access application just use
public String intercept(ActionInvocation invocation) {
Map appScope = invocation.getInvocationContext().getApplication();
}
That's done it, thank you very much. I was really stymied.

Noob question(s). Interceptor breaking forms, and Connection handling?
Hi folks, I have two questions, and I apologize for the n00b approach. I'm just teaching myself struts2, coming from a PHP background (but I've done plenty of JEE and Java Swing programming, so the language isn't completely alien :) Question 1... I have a Logon form that works fine without an interceptor, but as soon as I add one, my getUsername() and other methods fail (the username is null). Struts.xml: http://pastebin.stonekeep.com/1893 DBInterceptor: http://pastebin.stonekeep.com/1894 Logon.java: http://pastebin.stonekeep.com/1895 If I uncomment the interceptor line in my struts.xml file, the Logon form validator fails. Line 29 shows 'null' in Logon.java. If i leave it commented out, it works fine. Question 2... In Logon.java, I'm using the execute() method to set up my JDBC connection (as pulled from my JBoss container datasource), setting up the Connection, and making the call. Wouldn't it make more sense to do that in an interceptor around every class, and do something like ic = new InitialContext(); dataSource = (DataSource)ic.lookup(java:JQuoDEV); c = dataSource.getConnection(); Logon action = (Logon)invocation.getAction(); action.connection = c; return invocation.invoke() ; I tried doing this, and saw the connection start up, but the Action class kept having the connection as 'null'. I think I'm either misunderstanding how the interceptor / action sequence works, or doing something blatantly stupid.
