Natalia Kowalczyk commented on CACTUS-61:
-----------------------------------------
IWorkaround: To prevent NullPointerException when processing a page that
includes
JavaScript via src attribute, add following code at the beginning of the
endXXX() method before calling any HttpUnit methods that parse the
response:
public void endXXX(WebResponse webResponse) {
ServletUnitClient client = ServletUnitClient.newClient(
new InvocationContextFactory() {
public InvocationContext newInvocation(
ServletUnitClient client,
FrameSelector targetFrame, WebRequest request,
Dictionary clientHeaders, byte[] messageBody)
throws IOException, MalformedURLException {
return new InvocationContextImpl(request);
}
public HttpSession getSession(String sessionId,
boolean create) {
return null;
}
});
try {
webResponse = client.getResponse(
new InvocationContextImpl(webResponse));
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
}
// webResponse can be now queried
}
static class InvocationContextImpl implements InvocationContext {
private WebResponse webResponse;
public InvocationContextImpl(WebRequest webRequest)
throws MalformedURLException, IOException {
try {
webResponse = new WebConversation().
getResponse(webRequest);
} catch (SAXException e) {
e.printStackTrace();
throw new IOException(e.getMessage());
}
}
public InvocationContextImpl(WebResponse webResponse) {
this.webResponse = webResponse;
}
public HttpServletRequest getRequest() {
return null;
}
public HttpServletResponse getResponse() {
return null;
}
public void service() throws ServletException, IOException {
}
public Servlet getServlet() throws ServletException {
return null;
}
public WebResponse getServletResponse() throws IOException {
return webResponse;
}
public FrameSelector getFrame() {
return FrameSelector.TOP_FRAME;
}
public void pushIncludeRequest(RequestDispatcher rd,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException {
}
public void pushForwardRequest(RequestDispatcher rd,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException {
}
public void popRequest() {
}
public boolean isFilterActive() {
return false;
}
public Filter getFilter() throws ServletException {
return null;
}
public FilterChain getFilterChain() {
return null;
}
public void pushFilter(ServletRequest request,
ServletResponse response) {
}
}
> Cactus doesn't properly integrate w/HttpUnit. External Javascript generates

> Key: CACTUS-61
> URL: http://issues.apache.org/jira/browse/CACTUS-61
> Project: Cactus
> Type: Bug
> Components: Framework
> Versions: 1.5-rc1
> Environment: Operating System: Windows NT/2K
> Platform: PC
> Reporter: Evgeny Burya
>
> We've tried Cactus 1.4.1 and 1.5 Beta1.
> They both throw NullPointerException while trying to execute
> com.meterware.httpunit.WebResponse.getFormWithID() in endXXX() method. The
> problem is linked to Parsing of External JavaScript and Usage of window
> object
> (==null) in HttpUnit.
> This problem is really critical for us, So I'd like to get your quick
> response.
> Pls find the exception stack trace below (for 1.5 Beta1):
> There was 1 error:
> 1) testXXX(com.blablabla.UserSyncPrefActionHandlerTest)
> java.lang.NullPointerException
