RE: [HtmlUnit] Error when submitting a form based on javascript.s ubmit()

[Tom H. <Tom...@fu...>]

Ok.  What I have is a form that is submitted via an anchor tag.  The tag
calls javascript:formName.submit()

The exception I get here is this:
Exception class=[org.mozilla.javascript.JavaScriptException]
com.gargoylesoftware.htmlunit.ScriptException:
java.lang.NullPointerException
	at
com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine.execute(JavaScript

com.gargoylesoftware.htmlunit.html.HtmlPage.executeJavaScriptIfPossible(Html
Page.java:767)
	at
com.gargoylesoftware.htmlunit.html.HtmlAnchor.click(HtmlAnchor.java:68)

I have tried different approaches - like calling form.submit() in the test
harness - but this just does a javascript form submit().  If I do this I get
a different exception.  

java.lang.NullPointerException
	at
org.apache.commons.httpclient.HttpMethodBase.getResponseBody(HttpMethodBase.
java:670)

	at
com.gargoylesoftware.htmlunit.WebClient.getPage(WebClient.java:242)
	at
com.gargoylesoftware.htmlunit.html.HtmlForm.submit(HtmlForm.java:137)

What I am actually getting back from the server is a 100 - Continue -
presumably with no body.  What is actually happening is that the page should
be redirected to another page (struts forward).  So I'm a bit confused as
why I am getting errors?

You help is most welcome....

There isn't enough information here to be sure but I'd guess that this 
form contains an element with the name "submit".  HtmlUnit is then 
finding that element before it finds the submit() method and is trying 
to execute it.

Are you using 1.2.2 (the last released version) or the code in CVS?

This is happening inside commons-httpclient and it's quite possible that 
this is already fixed.  The version of commons-httpclient that ships 
with HtmlUnit-1.2.2 is alpha3.  They recently released beta1 which fixes 
a large number of bugs and may fix this problem.  Please try 
commons-httpclient-beta1 which can be found at:

http://www.ibiblio.org/maven/commons-httpclient/jars/commons-httpclient-2.0-beta1.jar

[HtmlUnit] building docs from CVS

[Christian S. <chr...@ne...>]

Hello,

I just downloaded the CVS source and built it using maven. So far so 
good. Now I am trying to find a way to also get at the documentation 
(assuming it is available).

I was not able to find anything like a "doc" target callable with maven 
(maven.. mystery). Calling the "site" target caused a CVS/SSh connection 
with sourceforge to be established under the user mbowler, whose 
password I did not have handy..

Is there a way to build/get documentation for HtmlUnit from CVS?

thanks,
Christian

"maven site" is the correct command.  The fact that it's hardcoded to 
use my username is a problem which I'll have to fix.

It's most likely trying to get to sourceforge to download the cvs logs. 
  Try building with the -o option - this tells maven that you are 
offline so it shouldn't attempt to connect to the cvs repository.  If 
you're going to be regularly running maven "offline" then you can set a 
property in build.properties to set this.  I think the property is 
"maven.mode.offline=true" but you'd have to double check that from the 
maven docs.

Mike,

thanks for the reply. This is what I get when running "maven -o site":

site:
     [echo] Generating the maven-changelog-plugin ...
maven-changelog-plugin:report:
     [echo] The Changelog is available in the online mode only.

     [echo] Generating the maven-changes-plugin ...

BUILD FAILED
null:-1:-1: <null> No goal [maven-changes-plugin:report]
Total time:  9 seconds

I also tried the ant build, but it created documentation with all broken
(empty) html files.

thanks,
Christian

I did see your previous private email but I've been having email 
problems this morning :-(  They seem to be fixed now  <crossing fingers>

Try "maven -e -o site".  The -e tells maven to dump out a full stack 
trace when something goes wrong.  This is usually enough to figure out 
what is failing.

I just tried "maven -e -o site" on my machine and it worked fine.  What 
version of maven are you using btw?  I'm currently using a version 
pulled from cvs sometime last week.

The targets for docs in the ant build are no longer usable and should be 
removed.  I'll add that to my todo list.
