It would appear that a page refresh is being triggered every time the 
page gets loaded and that you're consequently in an infinite loop. 
Refresh can be triggered by javascript (onload handler) or a <meta> tag 
or a refresh header in the http response.

I assume that this page loads fine in a browser btw.

The first thing I'd try would be a breakpoint or print statement in 
HtmlPage.executeRefreshIfNeeded() to see what specifically has triggered 
the refresh each time.

Re: [Htmlunit-user] Javascript Error

[Alexei G. <al...@go...>]

Hello Dave and Mike,

I had to implement some methods for some host objects at the time of 
HtmlUnit 1.2.3, and I used to modify SimpleScriptable get(...) and  
put(...) methods to dump javascript execution step by step. I think this 
methods did not change with HtmlUnit 1.3, so you con probably use my 
code from patch '[ 852838 ] Couple of javascript features for HtmlUnit 
1.2.3' for SimpleScriptable. This produces very comfortable step by step 
dump with a lot of information about how javasctipt is executed, and you 
will see the exception or 'null' returned somewhere in the dump, which 
is the reason for your JavascriptException.

Detailed description (changes.html)  is also in the patch.

Have fun

Alexei

[Mike B. <mb...@Ga...>]

The question I should have asked right off the bat is "what version of 
HtmlUnit are you using?".  If you're using something older than 1.3pre1 
then I'd recommend upgrading - there have been a lot of fixes put in 
since then.

There are tests for form["somename"] that are working in the latest code 
so I'm wondering if you're stumbling across something that's already 
been fixed in cvs.

Re: [Htmlunit-user] Javascript Error

[Dave S. <dav...@ca...>]

It is attribute ie name of the input field. form is the HtmlForm object.
So the first iteration should translate into like ...

var field = form["consols.file_num"];

All the standard javascript functions are implemented by the Rhino 
engine so I'd guess that Array and Function aren't the problem.  The 
parts that HtmlUnit needs to implement are the browser specific host 
objects like Form and Window and Frame.

It might be the array indexing part of Form that is the problem.

 > var field = form[oRequired[x][0]];

It would appear that field is null so form[] is not returning the object 
you need.  What is the value being passed into form[]?  Does it match 
the name attribute of an object inside that form?  Or is it an index?

This is a fairly generic symptom that means "some javascript object that 
you're trying to use hasn't been implemented yet".  The trick is to 
discover what javascript host object you're referencing so that we can 
implement it (or at least stub it out as a temporary fix).

Can you share the javascript (and the HtmlUnit code you're using to hit 
it)?  Even better, is this on a publicly available server that we could 
hit on remotely?

[Htmlunit-user] Javascript Error

[Dave S. <dav...@ca...>]

I saw this in the archives but no response so I guess I will ask it
again. I am testing an application that uses struts with javascript
field required checking when a form is submitted. When the user presses
save it checks that all of the required fields and filled in and if not
pops up an alert box with the fields that are required. I get the
following back trace when running my test.

There shouldn't be any connections left open between requests - what 
we're doing is supposed to be stateless.

Can you try a different version of commons-httpclient to see if that 
fixes the problem?  That's the part that actuallly makes the connection 
to the server.

http://jakarta.apache.org/commons/httpclient/

[Htmlunit-user] Connection Leak in 1.3

[<mbr...@vi...>]

There appears to be a connection leak in 1.3.  My test suite is running IIS out 
of connections.  I then get 403 errors.  I am creating a WebClient in my setUp
() function and setting it to null in my tearDown() function.  I don't see any 
API to directly close the connection.

RE: [Htmlunit-user] Performance Problems

[Mike B. <mbr...@vi...>]

Are you reusing the same WebClient instance?  As I remember, it caches some
data and the only way to flush it is to dump the WebClient instance and
create a new one.  This was pre 1.3 though.

Are you using the same WebClient or a new one each interation?

[Htmlunit-user] Performance Problems

[Biju A. <bij...@ya...>]

I am also observing some performance problem with
htmlUnit1.3, ,my requirement is to submit a form
500,000 thousand times

But after 10,000 or so it gives java out of memory
exception, I tried to execute the program by givimg
more memory 1GB (java -xm 1GB ProgramName), it goes
further more iteration but never reaches 500,000,
There is some memory leak in HTML Unit sources.

Thanks,
bijua

That fixed it.  Thanks again!

That's quite possible, most of it is being generated by ASP.NET server controls 
and we're dealing with Microsoft after all.  Have you ever looked at the HTML 
MS Word generates?  Egads yuk!

It wouldn't surprise me if ASP.NET intentionally generates HTML code that is 
hard to parse by Nekohtml.  Ok, call me a conspiracy theory nut.

Of course I am still unable to test the validators, but that is probably a 
whole new project.

Try adding this line before the tests run:
    System.getProperties().put(
       "org.apache.commons.logging.Log",
       "org.apache.commons.logging.impl.SimpleLog");

This will force commons-logging to use SimpleLog.  I'm guessing that 
it's defaulting to a different logger and as a result is ignoring the 
system property that you set.

I actually see my tests running 5-10% faster than before. Could it be that 
the HTML you're testing against is highly malformed and nekohtml must spend 
longer fixing it?

I would have expected "warn" to not show "info" messages but perhaps that is a 
misunderstanding of mine.  In any case, I changed the logging level to "fatal" 
and I still see messages like the following:

.Mar 23, 2004 12:22:52 PM org.apache.commons.httpclient.HttpMethodBase 
readResponse
INFO: Discarding unexpected response: HTTP/1.1 100 Continue

No.  I haven't timed my tests recently but they're certainly not in the 
4-5 second range.  I don't have any HtmlUnit tests on this machine but 
I'll pay attention when I next run my tests.

I would expect "warn" to allow warn, info, error and fatal to pass 
through.  Am I missing something?

The logging shouldn't have changed in any case.
