Are httpSessions thread safe?
Not sure how OT this question is. My current plan (unless this is bad for some reason, but if so, Ted H should change his example app :-) is to stash the hibernate Session for a user into his httpSession, and reuse it on each request. A Hibernate Session instance isn't threadsafe. I imagine if two really quick http requests got generated out of the same browser, all hell could break out. I guess I want to know if mortals like me need to worry about this. Does Struts (or the Servlet container FAIK) prevent this from occuring, or do I need to ensure this doesn't happen? If so, how? With a token or is there a better strategy? TIA -Joe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Check-boxes and formbeans
And it wont populate the unchecked ones... which means if each checkbox
doesnt have a unique value (ie: they all have value "true" or "on") you will
get an array containing n instances of "on" where n is equal to the number
of checked checkboxes of that name. Not very helpful.
Best bet is to give them individual values, or individual names, so you can
tell them apart when submitted.
ie: submission of the following:
will give you:
bob == String[] { "on","on","on","on" }
The idea is to use something like:
which will give you:
bob == String[] { "1","3","4","5" }
OR
bob1 == "on"
bob2 == null (assuming you reset it or its a request scoped form etc...)
bob3 == "on"
bob4 == "on"
bob5 == "on"
OR (maybe)
You could probably make use of indexed property names too (and init the
array of appropriate length in the reset method)
to get:
bob == String[] { "on",null,"on","on","on" }
Though I havent tried this variant, so I could be wrong, or the semantics
could be subtly different!

RE: Are httpSessions thread safe?
The sessions essentially just a sort of Map. Access to it may be threadsafe,
but the stuff thats in it is another matter entirely. Multiple requests
associated with the same session will execute simultaneously.
If you have >1 threads playing with the same unsafe object (which you just
happened to pull out of the session) then of course you will need to
synchronise their access to it externally.
ie:
Garthop unsafeObject = (Garthop)session.getAttribute(THE_GARTHOP);
synchronized(unsafeObject)
{
garthop.nargle();
}

I think using only one jsp wherein the number of form elements vary according to what you are doing can be considered as "anti-pattern" and is more of a JSP Model 1 design. The best way to make things work is to use a separate JSP for each form so that you can properly associate a separate ActionForm with each ActionMapping. If you wish to continue with the single jsp solution and still wish to use DynaValidatorForm, you can write your own Validator class and declare it in the validator-rules.xml. That way you can control how it will behave and validate the parameters... -Yves a.k.a. the witness to your long debates with Chad regarding morality and politcs :o) -Original Message- From: Marco Mistroni [mailto:[EMAIL PROTECTED] Sent: Thursday, December 18, 2003 1:30 AM To: 'Struts Users Mailing List' Subject: RE: validation and DynaActionForm / concrete question Hi Wendy, Only a little problem..

Re: Enhancement Request or Possible Alternative?
I have a commercial Struts product that includes an event that is generated when a new action is called. I built it so that one can clean up any session stuff when going to another action for large projects. We could work out something VERY reasonable. .V Hookom, Jacob wrote: We are doing a lot of module switching or multistep workflows (which we handle fine through session beans) but at the same time, users are allowed to jump to different pages and we would like to capture a "leave" event when they aren't within a set of mapping(s). I'm wondering if anyone has solved this problem because it would also allow for constraints on workflows at the action level (if you leave pages X,Y,Z then fire Action 'CheckSession').

Data transfer From Struts to JavaScript
Hi All,
I have jsp code below try to implement dynamic dropdown list
I utilize javascript code Dynamic Option List from
http://www.mattkruse.com/javascript/
I want 4 line hard code below (from that jsp code)
listB.addOptions("1","bpp2","7","bpp3","8");
listB.addOptions("2","bdl1","4","bdl3","5");
listB.setDefaultOption("1","7");
listB.setDefaultOption("2","4");
to be replace with dynamic value extract from:
become something like below
listB.addOptions( location[1].locationId, machine[1].machineName,
machine[1].machineId, machine[2].machineName, machine[2].machineId, ...,
machine[N].machineName, machine[N].machineId );
listB.addOptions( location[2].locationId, machine[1].machineName,
machine[1].machineId, machine[2].machineName, machine[2].machineId, ...,
machine[N].machineName, machine[N].machineId );
...
listB.addOptions( location[M].locationId, machine[1].machineName,
machine[1].machineId, machine[2].machineName, machine[2].machineId, ...,
machine[N].machineName, machine[N].machineId );
listB.setDefaultOption( location[1].locationId, machine[1].machineId );
listB.setDefaultOption( location[2].locationId, machine[1].machineId );
...
listB.setDefaultOption( location[M].locationId, machine[1].machineId );
THE PROBLEM is:
All properties I need, inside
But I don't know how to transfer Location property (locationId) --as Object
array at Collection locations-- and Machine properties (machineId,
machineName) --as Object array on each Location-- into dynamic code above to
replace 4 line hardcode above.
Anyone expert out there can help?
Really appreciate your help.
TIA

RE: Enhancement Request or Possible Alternative?
Hi, Did you have a look at the workflow extention for struts?I wil advice you to have alook at the demo application to see if this is what you are looking for. http://www.livinglogic.de/Struts/demoApp.html And also the site has some introductory material...And best of all it is Open Source as well...:-)) It has some similar concept.You can configure actions to make them part of a workflow.And then you can catch when the user leaves the workflow.And then there are various alternatives like you can force them to stay in a workflow or allow them to branch to another workflow. It is highly configurable and does need any code change, just twicking the ActionMappings... regards, Shirish. -Original Message- From: news [mailto:[EMAIL PROTECTED] Behalf Of Vic Cekvenich Sent: Thursday, December 18, 2003 10:42 AM To: [EMAIL PROTECTED] Subject: Re: Enhancement Request or Possible Alternative?

html:select default value problem
Hi, I know this has been talked about before, and I'm pretty sure I understand the concept, but I don't know why this is not working. The default option for an html:select is not being displayed. I have an ActionForm in request scope called "BusinessForm" that is populated. The "status" property has a value of "1" as verified by sticking in a bean:write, but the select list shows the value="0" option as the default item when I load the page. I have twelve other html elements on the page, and they all show the correct defaults, except for this html:select. Am I not seeing something in the code below... thanks...keith --- 0 - INACTIVE 1 - ACTIVE ...

You are missing this one:

That's because you were missing the JSTL taglib directive
above.

Why are you defining an action path at all.
Once you add the JSTL taglib directive the following
line places the value in the session. There is no
need to submit.

You could use Struts-EL and do something like:
The Struts-EL taglib and jar file can be found in the /contrib directory
of the Struts distribution.

Once again, this is because the JSTL taglib directive is missing.

RE: Help needed in form beans
You may want to consider creating a separate object to hold these values in the session and use your form beans for data input. This way you can decide when to populate your form beans with the data that you've captured in the session. To control when reset() affects my form properties I subclassed the action form and subclassed ActionMapping to add an isReset() setReset(boolean reset) methods so I can declaratively define when reset is to be used by adding the following line in my struts-config file: robert > -Original Message- > From: vasudevrao gupta [mailto:[EMAIL PROTECTED] > Sent: Thursday, December 18, 2003 12:30 AM > To: 'Struts Users Mailing List' > Subject: Help needed in form beans > > > > Hi All, > > I have a same form bean for 5 JSP's(JSP1,JSP2,JSP3,JSP4,JSP5) > > All the JSP's use the same form bean.I am keeping the form bean in the > session scope. > > When ever I use JSP1, JSP3, I want to see the blank screen even if there > are some values in the formbean. > But, in other JSP's, I want to see the screen with prepopulated values. > I tried using reset() for this and I have set all the values in formbean > to null.But reset is getting called > for all the action.I want reset to be called only for JSP1,JSP3. > > Please provide any direction on this > > Regards > VasudevRaoGupta > > > Confidentiality Notice > > The information contained in this electronic message and any > attachments to this message are intended > for the exclusive use of the addressee(s) and may contain > confidential or privileged information.

RE: Are httpSessions thread safe?
If Hibernate sessions are not thread-safe by design, then stuffing one in a web
app session and wrapping it with your own synchronization doesn't seem like the
right approach. I've never actually used Hibernate, so I could be way off base,
but it sounds more like a job for a filter. The filter would initialize the
Hibernate session and store it as a request attribute before any other request
processing. It would then also tear down the Hibernate session at the end of the
request. Are Hibernate sessions expensive enough resources to warrant creating
only one per web app session? Another approach might be to set up Hibernate
sessions as thread-local variable...

Using Iterate Tag !
Hi All,
I am new to struts world.
I have a problem in the iterate tag. Here's the code snippet..
My reset method & other methods in the createAbstractForm class are:
public void reset(ActionMapping mapping, HttpServletRequest request)
{
reqdEquipmentList = new ArrayList();
this.rowCount = request.getParameter("rowCount");
int count = 0;
if (rowCount != null) {
count = Integer.parseInt(rowCount);
for (int i = 0; i < count; i++) {
reqdEquipmentList.add(new
RequiredEquipmentVO());
}
}
public void setRowCount(String string) {
this.rowCount = string;
}
public String getRowCount() {
if (this.reqdEquipmentList != null) {
return "" + reqdEquipmentList.size();
}
return rowCount;
}
public ArrayList getReqdEquipmentList() {
return reqdEquipmentList;
}
public void setReqdEquipmentList(ArrayList reqdEquipmentList) {
this.reqdEquipmentList = reqdEquipmentList;
}
I am not able to get the values entered on the screen back in action
class
Any one, please help tell me what is wrong in the settings or code.
Thanks & Regards
Shree

Re: Validate method in action form
Another approach would be to create a base ActionForm with the properties, and then extend it for each validation instance. You can also use the came ActionForm class in multiple form-bean elements, and then use the Struts Validator to give each form-bean it's own validation suite.

Re: Tiles in Struts 1.1 - TilesRequestProcessor
The PlugIn takes the liberty of setting your RequestProcessor to the TilesRequestProcessor for you. You only really need to worry about it if you choose to use a custom RequestProcessor of your own; in that case, you'd need to extend the TilesRequestProcessor if you want to use Tiles functionality -- the PlugIn class is not "self-contained". Since the TilesRequestProcessor is totally compatible with non-tiles use, I wonder if we ought not just merge it in with the base RequestProcessor and eliminate the confusion? There is an ongoing effort to break up the request processing cycle to make it more flexible, but until then, I wonder if this would be worth pursuing...? joe At 7:50 AM +0100 12/18/03, Jan Dirksen wrote: Hi i am using Tiles with the Plugin.tag in the struts-config.xml now i saw in the source, that TilesPlugin <> the TilesRequestProcessor. okay, however - but i saw in one config-file, that i could add the TilesRequestProcessor in the config of struts. since now i only "used" the plugin in the config. is it better to use the TilesRequestProcessor instead? -in sources i didn´t found anything like deprecated in the TilesPlugin.

RE: Are httpSessions thread safe?

The sessions essentially just a sort of Map. Access to it may be threadsafe,
but the stuff thats in it is another matter entirely. Multiple requests

There's nothing in the specs that guarantee threadsafe access to
session attributes.
A pattern I've become quite fond of is to create a single object (we
call it a "shell", analogous to an operating system shell) which
encapsulates everything you want in session context for a given user;
then put just this object into session scope, and use methods on it
to do everything else. This helps you apply synchronization where
appropriate. There's still a risk of a race condition involving the
initial creation of the shell (assuming you do something like check
the session to see if there's a value under the key you use for the
shell) -- you can put that in a block synchronized on the session
object:
MyAppShell shell = null;
synchronized (session)
{
shell = (MyAppShell) session.getAttribute(SHELL_KEY);
if (shell == null)
{
shell = new MyAppShell ();
session.setAttribute(SHELL_KEY, shell);
}
}
If the "shell" concept seems like high overhead to you, you can still
synchronize accesses on the session object along those lines; you may
just have more trouble keeping track of all the places it needs to
happen.

Re: Weblogic 8.1 - Error in using tag library
I am sending this message so that if somebody else faces a similar problem they will have an answer to it instead of a hanging thread. The project I am dealing with was purchased and I pulled that project from a version control system on to JBuilder. Since I wanted to use the "struts visualization" capacity of Jbuilder, I mentioned that to JBuilder that this is a Struts Project. And JBuilder overwrote all the tld files with its own version, which clashed with the struts.jar I had. Meanwhile I was deleting certain "attribute" elements from the struts-html.tld file to get rid of the errors for setter methods for those attributes. It did help me understand the issue though!

RE: URGENT - Help defending Struts
This question comes up periodically, so I started a list of Struts-powered sites. http://simonpeter.com/techie/java/struts/sites.html I hope this helps. I know that I wouldn't like to think about not using it on the Intranet application that I head up the development team for. It has greatly aided our productivity and has now come through it's second peak season with flying colours. We started with Struts 1.0 and with a little help from Chuck Cavaness we were early adopters of 1.1. :-) Simon >-Original Message- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] >Sent: Thursday, December 18, 2003 9:49 AM >To: [EMAIL PROTECTED] >Subject: URGENT - Help defending Struts >Importance: High > > >All: > > > >Our CIO is currently fighting the use of Struts by saying that >it is not >widely used in B2C sites.

Re: URGENT - Help defending Struts
what frame work does he want to use then? Im not a struts user yet, but from what i see the framework is not BtoC / BtoB specific. imo. im guessing the cio hasnt even looked at struts to see if it would help provide support to the project. next my question is how big is the site? if its just a few pages. i would guess jsp with beans would do it struts would most likely be over kill. but if it has a larger group of features/functions struts would serently in that development. does that make a valid argument with out knowing much about the project. - Original Message - From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, December 18, 2003 10:48 AM Subject: URGENT - Help defending Struts All: Our CIO is currently fighting the use of Struts by saying that it is not widely used in B2C sites.

RE: Are httpSessions thread safe?
Synchronizing on the session object may cause you all sorts of grief...or it may
not. It all depends on your container. The spec makes no guarantees about the
identity of the object returned by methods like PageContext.getSession or
HttpServletRequest.getSession. For example, here's a test JSP:
<%@ page contentType="text/plain" %>
<%
out.println("session:" + session);
out.println("pageContext.getSession: " + pageContext.getSession());
out.println("request.getSession: " + request.getSession(false));
out.println("request.getSession: " + request.getSession(false));
%>
Here's the output from TC 4.1.24:
session:[EMAIL PROTECTED]
pageContext.getSession: [EMAIL PROTECTED]
request.getSession: [EMAIL PROTECTED]
request.getSession: [EMAIL PROTECTED]
And that's just within the same thread! I'm pretty sure TC 4.1.29 does return
the same instance, but just remember it's not guaranteed.

Re: URGENT - Help defending Struts
Our CIO is currently fighting the use of Struts by saying that it is not widely used in B2C sites. Does anyone know of any sites, preferably commerce sites that are using Struts? This would be extremely helpful. The CIO of a company as big as Accenture is going to decide whether Struts should be used or not based on whether or not anyone else is doing it? That's pretty weak. You'd think he'd at least have some trusted technology advisers that could help him decide based on the merits instead of just watching the crowds. Isn't innovation a big buzzword for consulting companies like that? My last project, a collaborative commerce project with a major lawn and garden equipment manufacturer, is built entirely upon Struts, and is already available for dealer registration; the public should be able to use the client's site to purchase tractors and accessories from local dealers in Q1 2004. My company has also developed a number of applications in the home appliances industry for direct to consumer and manufacturer-collaborative appliance sales which were either built from the ground up with Struts, or are gradually being ported to Struts. We also use Struts to run the primary consumer facing sites for companies in home furniture, office furniture, and personal healthcare products which don't currently have commerce components. But hey, if he wants you to write your own web application frameworks from the ground up, and internally perform all the testing that a large user community has already done on the Struts codebase and train all your new employees on the internal way to do it instead of hiring people who might come in already experienced in a framework well, that's one way to do it.

When you add in that they're a consulting company whose clients are big companies, it even makes a sort of sense. Big companies like Accenture's clients are risk-aversive.

Re: Are httpSessions thread safe?
Even though you got a few different objects with those calls, they all
represent the same conceptual "session" underneath. The concept of a session
would be worthless otherwise. In other words, if you stash a reference to
some object in the session, you will be able to get a reference to that same
object from any of the session objects returned by those calls (even though
the object representing the session itself may be different from call to
call).

Re: URGENT - Help defending Struts
I am sure part of it is just that he doesn't want to choose something that doesn't have a lot of mind/market share. How many people use something is a decent (but not perfect) indicator of how likely it will be that support will be available in the future, and that the skills acquired in learning and using the tool will have value in the future. Perhaps a good supporting argument for the CIO would be how many messages have been posted in response to your question in such a short period of time -- or how many messages are posted on this list per day. Struts is about as active as any project that I know of, and has been for long time. :-) -Max - Original Message - From: "Joe Germuska" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Thursday, December 18, 2003 8:13 AM Subject: Re: URGENT - Help defending Struts > >Our CIO is currently fighting the use of Struts by saying that it is not > >widely used in B2C sites.

Re: Are httpSessions thread safe?
The point is about synchronizing on the session object, in which case it makes
all the difference in the world that different instances are used to represent
the same conceptual session.

RE: Are httpSessions thread safe?
Yuck. And may I say, "Yuck", again?
It's not the Session object per se, as much as it is the particular
attribute I want to store there.
It does strike me that the storage of a Hibernate Session in the
httpSession is a fairly common thing, so I doubt this bites people very
often. It does seem to have the potential to do so.
In the "real world" why is this not too big of a deal? Or should it be
considered one?
I suppose that unless you've got time consuming requests, or the user
hits some button on the browser twice in rapid succession, it's probably
okay. A token could effectively prevent this type of condition I
suppose.

The concept of a session would be worthless otherwise. In other words, if you stash a reference to some object in the session, you will be able to get a reference to that same object from any of the session objects returned by those calls (even though the object representing the session itself may be different from call to call). Sure, but Kris is right -- that doesn't mean that you are correctly synchronizing access to the session -- object locks are based on object identity, not the conceptual identity of something they contain. Thanks to Kris for pointing that out -- I'd say that furthers the rationale for using your own objects to encapsulate the session "environment" in your application. If you moved my code block into a PlugIn or other expert who was responsible for instantiating and retrieving the shells, then you could just synchronize the access methods on the expert. You might still run into issues if you were running in a clustered environment -- I don't have much experience in that kind of deployment.

Hello Russell, you might want to have a look at http://nagoya.apache.org/wiki/apachewiki.cgi?StrutsWebLinks I also found the following site: http://www.isdcards.com ..but you'll probably find many more searching the Internet (for example, if you search google for "powered by Struts").

Struts test cases
Hi,
Has anyone used WSAD 5.0 with StrutsTestCase 2.0 ?
I've only succeded to make it work after several operation which don't inspire
me much confidence, or maybe is just me taking the hard way.
Is there anyone there who used this and can give me some hints?
Thanx,
Ovidiu
PS: For anyone interested here are the steps I took to make it work the way it
does
[1]. in setUp() add
setContextDirectory(new File("D:\\workspace\\strutsJunit\\jsp"));
setConfigFile("/WEB-INF/struts-config.xml");
[2.]Replace the servletunit.ServletContextSimulator getRessource() method
content with
try {
return this.getClass().getResource(path);
} catch (Exception e) {
return null;
}
[3.]execute ant to build a new strutstest-2.0.0.jar (the new one has 42K)
[4.]replace in the /WEB-INF/lib/ strutstest-2.0.0.jar (38K) with the new one
[5.]In your /WEB-INF/classes/ create a directory called /WEB-INF/ and copy
struts-config.xml and web.xml there
Run your tests

logic:iterate inside a logic:iterate ??
Hi
I'am a Struts newbie, sorry if it is a "classic" question.
My question is about logic:iterate
I have a vector of documents.
In my application a document is a vector of LabelValueBean. I wish to
write both the label and the value.
I wish to write all my documents so I iterate through my vector of documents.
But after that how can I iterate through my vector of LabelValueBean ???
Basically here's what I want to do :
for_each_document
{
for_each_LabelValueBean_in_the_current_document
{
write LabelValueBean.Label;
write LabelValueBean.Value;
}
}
thanks for you help

RE: Are httpSessions thread safe?
I saw these. I just had this grand idea of minimizing the Hibernate
connections by doing what Ted did in his example -- not actually
discarding a user's Hibernate Session until his httpSession expired.
I've never messed with ThreadLocals before but I suspect that the
attempt to put a ThreadLocal into a httpSession I suspect would be funny
to watch.

Re: Are httpSessions thread safe?
Agreed. I wasn't thinking that the question was to literally synchronize on the session object itself. I see now that that may have been the original intent. Synchronizing on the session object itself seems like a really dangerous idea to me (invitation for deadlock, performance issues). And Kris's test shows it probably wouldn't do what you expect it to anyway. -Max - Original Message - From: "Kris Schneider" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Thursday, December 18, 2003 8:32 AM Subject: Re: Are httpSessions thread safe? > The point is about synchronizing on the session object, in which case it makes > all the difference in the world that different instances are used to represent > the same conceptual session. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Are httpSessions thread safe?
That second one actually works great, 43.html. Since each request is
running in its own thread it has the possiblity to create a new hibernate
session for every request, but it only creates it if you call the getSession
method on the filter. And at the end of the request that session is
destroyed.

That second one actually works great, 43.html. Since each request is
running in its own thread it has the possiblity to create a new hibernate
session for every request, but it only creates it if you call the
getSession
method on the filter. And at the end of the request that session is
destroyed.

RE: Are httpSessions thread safe?
I guess creating Hibernate Sessions and Destroying them on every request
isn't as bad as I imagine it is?
I figured creating the session when the user showed up, destroying it
when his httpSession expired, and reconnecting/disconnecting on each
request was strictly better.
I guess doing this isn't quite worth the effort? No one else seems to
mind :)

Re: Are httpSessions thread safe?
Most (all?) containers pool the request-handler threads, so it won't be
creating hibernate sessions for each request. It would still be thread safe,
since a single thread won't be used to process two requests simultaneously.
This sounds like a good approach to me -- safe and likely to perform just
fine.

Re: Are httpSessions thread safe?
Well what that plugin does is IF you request a session from it, it binds a
Hibernate Session to your current executing thread. thus if you are using
actions, anywhere in that action and in the resulting jsp the same session
is used if you requested it again. And on requests for images or whatever
since its never requested it doesn't get created. If you are using a
connection pool like DBCP or something it shouldnt be a problem at all.

Vic, I did notice that there is pattern matching now available on the CVS head, but I was wondering if your solution was done with Struts as is, or if you had to make modifications to the Struts Config DTD and/or RequestProcessor?

From the "${area.name}" it looks like you're using Velocity Templates. I
thought Velocity couldn't mix with JSP's like that (My impression from ch 17
of 'Struts in Action'. How are you mixing the two? (Or is there a Velocity
update which allows it?)
I should have noted that I am using tomcat 5.0 also. I am not using
Velocity, but merely JSP EL. So no mixing. In debugging, the EL is
returning the right thing. Struts is stripping the last .something

I guess barring any other comment I will just add a bogus extension to
make sure I have no more conflicts.

Re: Is there a way to set variable using Struts?
I think that this way is not good. First step (if=1) woks fine, but after
that it always will have value equal 2 so not equal 1 then second step will
always be executed and finally counter will have value 1.
I would prefer defining another bean on start, something like this
tableCounter = 2;
tableCounter = 1;

action local forward to a tile
hey all, i'm running into an issue I just cannot seem to figure out. It deals with trying to define an action local forward whose path is a tile. I searched the mailing list and found all sorts of questions and comments on this, but none of the solutions helped with my problem. I am using struts version 1.1.0. In web.xml I have defined the servlet section using the standard org.apache.struts.action.ActionServlet class: contoller org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml convertNull true validating true 2 In struts config, I have both defined the tiles plugin: as well as the tiles request processor (supposedly optional, i know, but just to be sure): However, with this setup, if i try to setup a forward to a tile i keep getting invalid path errors: ... I have verified about a hundred times that ".home.revenue" really is a valid tile name within my tile def: Can anybody please point out where I am going wrong? Thanks a bunch in advance...

RE: Disable INFO Log messages in struts
The debug action init param has no effect. Struts totally does logging through commons logging, which you've said you've set up to use log4j. So in your log4j config file, add a logger for org.apache.struts and set it to an appropriate level. You may also have to set additivity appropriately depending on how your root logger is defined. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, December 18, 2003 3:01 PM To: [EMAIL PROTECTED] Subject: Disable INFO Log messages in struts I have set DEBUG to Zero in the action init parms.
