RE: Hot deploying struts application

[George.Dinwiddie]

Yes, I'm using Tiles.  I've just got the Auto Update Interval set for
3000 milliseconds ("Configuration | Applications" on the WL console) and
I drop the war file into the incoming directory.  The appserver explodes
them and restarts the application.  Over time, it loses memory and I
have to restart the server.

>From your error message, it looks like Weblogic is replacing the
TilesRequestProcessor class but not initializing it.  I've had trouble
with WL deserializing classes that shouldn't be serialized as a shortcut
to reloading them.

RE: Query regarding file upload

You would have to control this on the client end, perhaps using
javascript to break the transaction into two HTTP requests.

RE: file download without opening a window

[George.Dinwiddie]

You need to serve the XML file, itself--not forward to a JSP.  In your action 
class, one of the parameters is an HttpServletResponse instance.  Call 
addHeader() on that object.  Then copy the file contents to the OutputStream 
returned by getOutputStream() on that object.  Finally, the action class should 
return null, indicating that it has taken care of responding to the request.

 Hope that helps,
   George

RE: Filter problem

[George.Dinwiddie]

How are you inserting your XML/HTML into the JSP?

I don't think the filter method is causing your problem.  I think you're
not expressing that the output should not be filtered.  If you're using
 you might want to add 'escapeXml="false"', for example.

RE: Handling breadcrumbs with Struts

[George.Dinwiddie]

Creating a working sample would be quite a bit of work, and I don't have time 
at the moment.  In a nutshell, I would have a bean something like:

public class Breadcrumb {
public String getName() {...}
public String getUrl() {...}
}

The BreadcrumbTileController would do something like

List breadcrumbList = getBreadcrumbsFromSession(request);
Breadcrumb breadcrumb = makeBreadcrumbFromRequest(request);
breadcrumbList.add(breadcrumb);
request.setAttribute("breadcrumbslist", breadcrumbList);

The BreadcrumbTile.jsp might contain something like





The tile definition would associate the controller with the tile:




Then define your default page layout to include the BreadcrumbTile.

A thousand variations are possible, depending on the context of your 
application.  Adjust to suit.

RE: Handling breadcrumbs with Struts

[George.Dinwiddie]

I would use a tile.  The tile controller can retrieve information from
the request and add it to a list kept in session scope.  The tile,
itself, can display that list as breadcrumbs.

RE: Struts2

[George.Dinwiddie]

It looks like you're requesting a page with suffix mapping ("helloWorld.do") 
but you've configured struts to use prefix mapping ("/*").  What happens if you 
change to "*.do"?

No, I wouldn't use referer for anything other than returning to a page
after intercepting an request (for login, perhaps).

I'm just suggesting having a filter in front of the pages that require
login and have it check the user's session for the appropriate
credentials for the page.

RE: Browser History by HTTP-REFERER

[George.Dinwiddie]

Do you realize that browsers are not required to send a Referer header?
And that many proxies strip out such a header?

You will have far better success if you create a robust application that
can do the correct thing even if URLs are received out of the expected
order.  Trying to hamstring the browser is an exercise in futility.

RE: Error with c:for Each and c:out

[George.Dinwiddie]

It's the javabean specification.  Normally the methods "getFoo()" and 
"setFoo()" operate on the property "foo".  The code doesn't really care what 
the property is called internally (it could even be calculated on the fly), but 
it infers the property name from the method name.

Normally variables in java begin with a lowercase letter.  See Sun's java 
coding standard for more, or William Wake's "Java Coding Standard on One Page" 
http://www.xp123.com/xplor/xp0002f/index.shtml

The method "getCheckPart()" will refer to a property named "checkPart".

A redirect is a message to the browser telling it to make a new request
for a different URL.  Since the browser is sending a new request, any
data you put into the old request goes away.  If you need to have data
available between browser requests, store it in the session, instead.

RE: interface for constants

[George.Dinwiddie]

One (of many) problems with this approach is that it may fail to
initialize, but that won't happen until the class is loaded at first
use.  If an application is broken because the database is inaccessible,
it's better to know at deployment.  I use a servlet startup listener
(javax.servlet.ServletContextListener) to perform initialization.

SSLEXT on a per-session basis

[George.Dinwiddie]

We have a situation where certain appservers are behind a webserver
proxy, but also available to internal users directly.  This means that
the SSLEXT plugin must sometime rewrite the URLs based on ports 80 and
443, and sometimes between 7001 and 7002.  This will remain constant
throughout a particular user's session.

I've taken a brief look at the SSLEXT code, and it doesn't look very
extensible (without modifications).  The SecureRequestUtils.computeURL
method is static, and the SecurePlugInInterface to which it delegates
the selection of port numbers is shared throughout the app (in
ServletContext) with no access to the incoming request.

Has anyone else ever slayed this particular dragon?  I'd hate to
reinvent the wheel unnecessarily.

RE: Junit tests on remote Struts application in Eclipse

[George.Dinwiddie]

Chris,

It sounds like you're trying to run the tests inside the container.  If
so, JUnit can't do that on it's own.  You can use Cactus to proxy from
the testrunner (outside the container) to the tests (inside the
container).

I've always found Cactus to be a bit of a PITA, however, and have
changed my testing strategy to avoid it.  My tests are split into three
groups:

 - POJO JUnit tests which test the java code and run very fast.  These
drive most of my development via TDD.
 - Tests that involve other systems, principally the database.  I
substitute a DAO factory that uses a local JDBC Connection instead of
getting a datasource from the container.  These tests check the
Persistence layer.  They're much slower than the ordinary JUnit tests
(particulary because they use DBUnit to set up test data), but they're
still faster and easier than in-container tests.
 - Acceptance or System tests that test the application as a whole,
running in the container, through the normal web interface (using
HttpUnit).  These don't have to test the edge conditions, because those
are tested in the other tests, above.

Hope that helps.

Use the pattern of redirecting to a GET after POST.  In other words, use

RE: The content of element type "web-app" must match

A. Lotfi asked:

[snip]

Generally that means that something is out of order or misspelled.  It's
a painstaking process to check the order of all the elements, but if
that's all the error message gives you, that's what you'll have to do.
I remember dealing with that with WebLogic 5.1, but it gave the line
number where the XML parser failed.

RE: Ejb

[George.Dinwiddie]

If you do a good job of separating your business logic from your
presentation, then it's quite easy to put that business logic into an
EJB behind a BusinessDelegate that implements the same API.  This ease
means that you can defer going to an EJB solution until you actually
need the advantages (principally transaction management, IMO) that EJB's
provide.

In pictures, I suggest going from

-- Presentation Layer --
-- Business Layer --

to

-- Presentation Layer --
-- Business Delegate --
-- EJB Remote Interface & Service Locator --
-- EJB Session Facade --
-- Business Layer --

You can even do this for only part of your Business API.  I've done that
where only part of the API needed the transaction services.

I'm not fond of Entity beans, but if you use a DAO interface, you can do
the same thing between the Business Layer and the Persistence Layer to
substitute Entity beans instead of some other DAO such as JDBC.

  Hope this helps,
George Dinwiddie

That sounds good.  I like to use a tile as the outer skin of the onion

I'm not sure about using 'DEBUG' as the name of an appender.  Why not
try something like 'logfile'?

I'm not very familiar with configuring Log4j using XML.  A simple

The directory needs to exist.  Log4j won't create it for you.

Do you see your log output on the console?

It will probably be relative to the current working directory where you
start Tomcat.

Commons-logging is most often used as a wrapper around Log4J, but it can
wrap other logging frameworks, too.  Maybe check what Tomcat uses

It's missing from log4j.properties (or xml).  See

you find it in your setup, add

log4j.logger.org.apache=DEBUG

and you'll get a bunch of logging.

I think you may need a  tag after the  to
make the value available.  See

html

I've blocked out much of this from my memory because JSTL is so much
easier.

RE: Struts with Eclipse 3.1

[George.Dinwiddie]

My point is that Eclipse does not, in the base IDE, have the knowledge to build 
and deploy a web-app.  You can get that capability with ANT, which gives you 
all the flexibility in the world about how you arrange your project, or with a 
plugin, which requires you to arrange your project in a particular way.

RE: Struts with Eclipse 3.1

[George.Dinwiddie]

If you don't want to build with ANT (or equivalent) then I think you must use 
one of the plugins with webapplication support.  These, in my experience 
(mostly with MyEclipse), require particular layouts of the source for it to 
work.

It seems to be your choice which work you want to do.

RE: Browser Back Button

[George.Dinwiddie]

I strongly recommend AGAINST that technique.

1. It's very narrow and easily circumvented (by turning off javascript, by 
opening an new window or tab instead of leaving the page you might want to come 
back to).

2. It's very user un-friendly.  It's against W3C recommendations.  It breaks 
the web paradigm.

In my opinion, it's better to learn to create web-apps that don't have an issue 
with the back button than to patch bad apps with bad bandaids such as that.

RE: Tiles without Struts

[George.Dinwiddie]

Hmmm...  You're right that http://struts.apache.org/ doesn't list any
1.3 versions in the menu.  If you go to the 1.2.x page and "download"
"development releases" you can find
http://svn.apache.org/dist/struts/action/ with later builds.

Standalone tiles may be downloaded at
http://cvs.apache.org/builds/jakarta-struts/nightly/sandbox/tiles-core/
per the short FAQ at
http://struts.apache.org/struts-action/struts-tiles/faq.html  See
http://wiki.apache.org/struts/StandaloneTiles for the status on this
project.

Hope this helps.

RE: Are layers 'that evil'?

[George.Dinwiddie]

It seems to me that the problem Paul Reedman describes isn't that of
building layers on top of frameworks, but of building frameworks on top
of frameworks.

I find that I often build an adapter layer around third-party subsystems
to create an interface written specifically in the terms of my
application.  That gives me a natural abstraction to use within my
application.  As a side benefit, I get a seam (to use Michael Feather's
term) for testing--I can test that my application uses the adapter the
way I expect and I can test that the third-party subsystem behaves in
the manner I expect.

Such an adapter is not a general purpose framework, however.  It's very
specific to the application.

I can't think of any time I've wrapped an MVC framework in this fashion,
however.  Instead, I wrap my application in an API that forms a
convenient Model for the framework.

Either way, I find it a good technique for keeping my business logic
distinct from, and not directly dependent on, the framework.

I don't thinks so.
 1. Object creation time is trivial compared with database access time.
 2. Keeping the resultset open hogs database connection resources.
 3. The gui and database should be independent, and free to evolve in
different ways.  There's hardly any point in using an MVC framework if
all you're going to do is make it a direct face of database tables.

You might want to consider using a single DTO at a time, based on the
needs of the GUI screen/process.  When running the GUI and Business
tiers in the same VM, I would skip the DTO altogether and use an
Interface, instead, for the Business API as seen by the GUI.  This can
be implemented by full-fledged domain objects.

RE: How to make work Log4j with Struts?

[George.Dinwiddie]

I don't see anything wrong, right off the bat, with your
log4j.properties file.  Where in the startup log are you seeing the "No
appenders" warning?  Could it be that something else is starting up
log4j prior to your application being loaded, and there's not
log4j.properties on the classpath at that time?

RE: White page flashing between request and response.

I would suggest sniffing the network traffic to see what's going on

If you're using Eclipse for J2EE development, MyEclipse is worth it even if you 
only use the JSP validation.  It's not perfect, but it's well worth the price.

As for the rest, I see you've already gotten some good answers and some 
irrelevant noise.  I can't understand why anyone would hang around a user list 
just to harrass the users of a framework they don't like.

I presume that you've never worked in a corporate environment.
Proceeding on that assumption, let me explain a little to you.

Scott Adams has made his fortune displaying the cynical view of managers
that you describe.  Indeed, from the point of view of the technical
staff or others with limited access to those managers, it often looks
like decisions are being made very arbitrarily.  In some cases, they
actually are.  Incompetent managers are probably as common as
incompetent developers.

In reality, most managers do have a brain and use it.  Most managers are
not merely trying to avoid drawing attention to themselves so they can
draw a salary for doing no work.  Believe it or not, most managers take
their jobs seriously and make the best decisions they can given the
knowledge they have and the circumstances in which they make them.  By
"knowledge they have" I don't mean technical ignorance.  Sure, some are
quite ignorant technically and most do not have the detailed technical
knowledge of a developer, but they also have knowledge of non-technical
issues of which most developers are rather ignorant.

You've extrapolated several suppositions, here.  Who says their beliefs
are misguided?  I presume from these statements that you're rather
young.  In my youth, I tended to believe that those who didn't agree
with my beliefs were misguided.  And I was not shy of telling them so.

But even supposing that I am right and they are wrong (and I no longer
believe that these are boolean values), I am unlikely to convince them
by announcing that they're all wrong.  They will naturally think, "On
the one hand, I have this kid without the experience to understand the
issues which I'm balancing telling me that I'm wrong.  On the other
hand, my view of the world and the way it works has done pretty well for
me so far."  Do you doubt everything you've learned when someone walks
up and says you're wrong?

I thought not.

Is your lack of success in convincing someone that they're wrong their
problem or yours?  Do you want to do something about that lack of
success?  Or do you like that status quo?

If you like futile arguments, then you seem to be doing a fine job on
your own.  But if you want to argue more effectively, then I can suggest
the AYE Conference (http://www.ayeconference.com/conference.html).  And
if you can't find the time or money to attend, there's still lots of
good information in the blogs and articles of the people who put on that
conference--more than you could assimilate in a lifetime.

Do you want to contribute to Struts and feel excluded?  Or are you
morally indignant based on higher principles?  I can't figure this out.

As for the technology, and the rules of running the project, in both
cases I'm glad that the wide world provides more than one choice.  I'm

I never said that the sky would fall in.  I just said that committing
code from a wide range of producers prior to review by a small group of
people deeply immersed in the project would reduce the trust in the
project.  You may have no objection to this, but you cannot make that
decision for others.  There are many companies using Struts for far more
important things than simple websites.  I believe that many of these
companies would be unwilling to trust Struts for these uses if the
project were to greatly open up the commit privileges.

Effectiveness of code review depends on the depth of that code review,
not merely the number of people who have reviewed it.  While broad
review, which any open-source project may have, can bring a benefit in
reducing errors, I have generally found it better for catching coding
errors than design errors.  In many cases, it weakens the review because
it dilutes the sense of responsibility.

I was using this as an example, and don't wish to debate the question of
open Wikis.  For the record, I have given up on maintaining the C2 Wiki
(after many years of contributing) because the cruft is added faster
than it can be cleaned, and it's no longer worth my time to work on it.
I rarely refer to it for reference, either, for the same reason.

You have an objective measurement of trustworthiness?  I thought that
trust was a human (or perhaps animate) value.

> George, I'm rather unconvinced by your arguments.

That's OK with me.  I'm rather unconvinced by your arguments.  I'm just
stating the case that, as it is, Struts is rather widely trusted for
enterprise systems.  I believe that much of that trust is due to the
empirical track record of the small team controlling changes to the
code.  I believe that much of that trust by those businesses would be
lost were this model of control to be radically altered.

I'm not saying that it would have more bugs.  I'm saying it would be
less trusted.  It's harder for me to trust a large group than a small
one.

There are other potential bad consequences than the two listed above.
Consider

3. Subtle errors and exploitable security holes get introduced, either
inadvertantly or intentionally.

While a revision control system allows backing out changes, each change
must be carefully considered.  A security hole or other error may not be
the result of a single change, but of multiple changes made in multiple
locations and, perhaps, at multiple times.

While open source allows a large number of eyes to see the code, it's
not that easy to review code in depth and spot such problems.  Much
trust is placed on the skill, attention, and thoroughness of the
committers.

Consider the C2 Wiki and Wikipedia as analogies.  Yes, it's easy to
delete obviously false information.  It's just as easy to reintroduce
it.  Keeping the worst of the cruft out is pretty much a full-time job
for volunteers who take on the task, and there's not even agreement
between them which is the cruft.  Subtle or infrequently viewed
incorrect information can, and does, remain for long periods of time.
Spectacular failures occur that make headlines in the mass news media.

I, for one, would never recommend to any business enterprise that they
use Struts for important applications if the source was not vetted and
controlled by a small, trusted committee.  Your needs may not have such
requirements for trustworthiness.

But if businesses were to abandon use of Struts for important
applications, would that be a reasonable trade-off for the contributions
of your talented, energetic person?  Or would the loss of talented,
careful people, who needed a framework for business use where large sums
of money are at risk, be a larger negative for the project?

You'll have to ask Microsoft why it works that way.

In the meantime, I would advise checking your site with Firefox so that

What browser are you using?  Note that a custom 404 page is still a 404
page, and Internet Explorer will insist on showing you its own 404 page
instead of the one sent by the server.

RE: html:link, etc, looking for full url, not just context name

[George.Dinwiddie]

Jim,

If you don't want advice, don't ask.  If you ask, don't get snippy about
the answers you receive.

Google and other indexing robots are perfectly capable of inferring the
full URL from a relative URL.  I may be wrong, but I think it's
significantly harder to "game" your Google placement than turning all of
your relative URLs into absolute ones.  No doubt you can find articles
and hire consultants who will recommend this, and other dodgy tactics,
that may have worked for a week or two in the distant past.

If you still want to tell me that I'm being a jerk for not giving you
the answer to the question as you phrased it, you might want to read
http://www.regdeveloper.co.uk/2006/02/27/perpetual_motion_apache/
starting with the part: 'why we may seem unhelpful when a question comes
across as "help me shoot myself in the foot".'

RE: html:link, etc, looking for full url, not just context name

[George.Dinwiddie]

FWIW, I've never had any trouble getting robots to index relative URLs.
In fact, it would seem pretty silly to me if all URLs on a site had to
be absolute.

The inclusion of query parameters in your URL is more likely to cause it
to be ignored than the use of relative URLs.

RE: BusinessObject and DataTransferObject

[George.Dinwiddie]

A Business Object is generally a part of the Domain Model (see
http://martinfowler.com/eaaCatalog/domainModel.html).  A Data Transfer
Object is a data "object" used to transfer information to/from a remote
system (see http://martinfowler.com/eaaCatalog/dataTransferObject.html).
I highly recommend Martin Fowler's book, "Patterns of Enterprise
Application Architecture."

I don't know Tomcat configuration, but with Weblogic, you can change the
context of the application with

/

in weblogic.xml.  I'd imagine that Tomcat has a similar setting.

Good!  I also recommend having the Session Bean methods call like-named
methods in a Business Logic class, doing similar catching of exceptions.
Then you can test your Business Logic without the container.  The
Session Bean is just a facade on the Business Logic, the same as the
Business Delegate is a facade on the Session Bean.  In fact, if I'm not
using EJBs, I'm likely to use the Business Delegate facade directly on
the Business Logic.  Then, if the transactional support of EJBs becomes
desirable, I just insert an extra facade layer in the code.

> We

Of course, but that can be done through the UI itself, rather than
inside the web container at the Action level.  It's more work in some
ways, but less in others.  And it gives you a warm fuzzy about the whole
application.

I don't think you'd have to throw and catch it.  I think it's sufficient
to create an instance of Throwable to check the stack trace.

Pretty much.  If your delegate API is defined as an interface, then it's
easy to create a mock or stub that implements that interface.  There are
even packages that will do it on the fly (EasyMock, for example).  You
can also do things like subclass your delegate and override certain
methods that might require container services.

Then you just need to have a way to insert these in place of the
production delegates.  If you're using dependency injection (a.k.a.
inversion of control) then you can inject them by that method.  If
you're using an abstract factory pattern, you can substitute a test
factory for the production factory.

No, but I'm saying that you'll likely find it messy and difficult to

I agree with Laurie that it's more practical to unit test in isolation,
and then system test the entire system.  If you cover all the boundary
conditions with your unit tests, then the system testing is a lot more
tractable.

Stubs, fakes and mocks are subtly different things.  For unit testing, I
think you'll still want to inject a fake or a mock that behaves (and in
the case of a mock, verifies the usage) the same as the real thing.  Not
only does this free you from difficult test setups, but it allows you to
create conditions that may be impossible to create using the real thing.

RE: [SHALE] Using the Test Framework

[George.Dinwiddie]

What Cactus does is allow your test code to run from within the
container, controlled by the same test code outside the container.  It
connects the two with a proxy arrangement.  It can call anything in your
code or available to your code.

Cactus *is* a PITA to work with, and complicated to think about, IMHO.
I've gotten away from using it in recent years by abstracting interfaces
that might need to do things like JNDI lookups and providing mock
versions for out-of-container testing.  In my experience, it things are
hard to test, it generally indicates design issues.  Usually the
dependency chains are long and concrete.  Constructs like a Business
Delegate or Abstract DAO Factory help break up the dependencies.

You'll probably still find Michael Feather's book worthwhile.  I
certainly did, even though I'd read some pre-publication excerpts.  For
dealing with the politics, I recommend the works of Gerald M. Weinberg.

Certainly.  And, as it's already posted on a public mailing list, it's
hardly necessary to make it anonymous.  The opinions expressed are those

Fargo.

I can imagine.  I think the key is to try to make progress on cleaning
up the system, without biting off more than you can chew.  Even the best
client with such a system is unlikely to find fixing everything
affordable.  The only strategy that can work, in my opinion, is to
attack the issues that cause the most problems for the enhancements that
you need to make, and wall off other areas to tackle later.  It can be
tricky to pull off.  Sometimes a "deprecation refactor" works for this:
create a new way for part of the system, and later migrate other parts
over to it.  This is a messy process, of course, and in the interim
leaves the system even a bit more confusing.  Again, this is stuff that
Michael Feathers has covered well.  You may want to check the yahoogroup
on the topic (dormant now, I believe) and other resources on the web.  I
still find the book a good reference, however.

Keep in mind that the goal is to deliver business value to the client,
while paying down the current debt.  There is no silver bullet to make
the problem go away--it takes discipline and effort.  The client
currently owns the problem.  Successful development teams rarely
propose, "If you pay us fairly for this bit of work, we'll do anything
else you need for free."  I wouldn't accept such a proposition, either.
But I would propose to work in the client's interest, and preferably in
close communication, to accomplish the client's goals in the most
economical means possible.  And "most economical" doesn't mean "quick
hack" because that quickly leads to higher costs as the code becomes
harder to work with.

I'm no expert in tuning database access, but even for a one-time use,
Oracle can do a better job if you use a PreparedStatement rather than a
Statement.  Of course, if you can re-use that PreparedStatement SQL,
Oracle can gain a lot more from its optimizations.

I recommend the book Working Effectively with Legacy Code, by Michael
Feathers.  And the book Refactoring, by Martin Fowler.  These two will
sharpen your tools for working on this system.  They'll also help you
concentrate on what you need to clean up for the work you're doing, and
leave aside cleaning up other parts until it's necessary.

Ward Cunningham calls this situation "Design Debt."  By not keeping the
code clean as you go along, you build up a balance of design debt.
Every thing you do becomes a little harder to do.  This is like paying
interest on the debt.  For short periods, this can be a reasonable
tradeoff, but many teams only make the minimum payment, letting the
mess, and resultant difficulty, grow over time.

Personally, I think it's irresponsible to hand the client a system
that's wallowing in design debt.  And many clients are not able to judge
this for themselves (as they might look at the balance carried on a
credit card).  Whether they paid less for the messy system than they
might have for a clean one is a moot point, after the fact.  (And
generally I think the answer is "no.")  The face is that they own a
system that's going to be harder, and therefore more expensive, to
maintain.

Who bears that cost depends on how it's presented to the client.  If the
estimator didn't take this situation into account when they negotiated
the job with the client, it can be very difficult to convince them
later.  And since they've probably already dealt with a development team
that delivered less than was purchased (i.e. the messy system), they'll
already be predisposed to distrusting development teams.  Gaining that
trust is the key, but it's not easy.

This is a question for your persistence layer, not Struts.  (Though you
will need to convert the image from a byte[] to an image.)

It sounds like you've not done any basic homework on filters.  You might
want to start with

RE: Populate action

[George.Dinwiddie]

I would use a UserCredentials interface that gets passed down to the DAO.  My 
action would be more like:

public void execute(...) {
// marshall the input 
UserCredentials userCredentials = new 
PresentationLayerUserCredentials(request);
// invoke the business layer
PapersList list = PapersList.find(userCredentials);
// save the results
request.setAttribute("PapersList", list);
// redirect
return mapping.findForward("success");
}

Note that
 1. The PresentationLayerUserCredentials knows how to extract the proper 
information from the request, encapsulating that knowledge.
 2. The business layer just uses the generic UserCredentials interface.
 3. The list to be displayed is encapsulated in an object, not a naked 
collection.
 4. The action doesn't call directly to the DAO.
 5. The UserCredentials interface has a method that returns a value useful for 
the DAO to use in a SQL WHERE clause.

The business layer class might PapersList include something like:

static PapersList find(UserCredentials userCredentials) {
PapersList results = new PapersList();  // create an empty list
dao.find(results, userCredentials); // fill the list from 
the dao
return results;
}

HttpUnit uses Rhino for its javascript support.  The problem is
principally that Rhino tries to implement the EcmaScript spec, which is
not at all what Internet Explorer does.  There are significant
differences, especially in the Document Object Model.  You'll run into
the same issue when testing with Firefox.

Since you're running on Linux, IE is not an option, and Watir is not yet
an option.  Perhaps Selenium (http://www.openqa.org/selenium/) would
help.

RE: Just adding log4j.jar to struts 1.2.7 project under weblogic causes stack trace

[George.Dinwiddie]

Could there be something outside your app that's using commons logging,
and therefore needs log4j once it's installed?  Try putting the
log4j.jar in your server classpath, e.g., weblogic81/server/lib, and see
if that helps.  I'm really grasping at straws, here.

Alternatively, could there be another log4j.jar in the server classpath?
See http://forums.bea.com/bea/message.jspa?messageID=200071715&tstart=0
and http://forums.bea.com/bea/message.jspa?messageID=200071922&tstart=0

Is your jar named "log4j.jar" and not something else?  I turned up a
this
(http://forums.bea.com/bea/message.jspa?messageID=200060394&tstart=0)
related to WLS 7.0.

Have you tried flushing out the .wlnotdelete directory?  We've had
numerous issues with WLS deciding that it didn't need to deploy the new
code because it thought the previously deployed version was good enough.

Have you looked in the server log (either in the console that starts the
server or through the management console), to see if there are any
clues?

Are you deploying this as a .war file or .ear file?

RE: Just adding log4j.jar to struts 1.2.7 project under weblogic causes stack trace

[George.Dinwiddie]

Are you using the jdk that comes with WebLogic?  Under WebLogic 8.1.2,
that was in C:\bea\jdk141_05 for my installation.  WebLogic plays some
intricate games with the ClassLoader.

RE: Just adding log4j.jar to struts 1.2.7 project under weblogic causes stack trace

[George.Dinwiddie]

None that are related to log4j.

It's curious that your stack trace doesn't name the class that can't be
instantiated.  What version of Java are you using?  This might be a
question for BEA.

RE: Just adding log4j.jar to struts 1.2.7 project under weblogic causes stack trace

[George.Dinwiddie]

I've used log4j 1.2.9 with struts 1.2.7 and Weblogic 8.1.2 without any
problems.  Do you have any indication of what class is not being found?
Are you missing a dependency for an appender that you're using?  (See
http://www.jguru.com/faq/view.jsp?EID=1007095, though this may be
out-of-date.)
