Re: Ant Junit GwtTest
Hi, I applied all you suggestiones and it works !!. Thank you very much. Best regards. On 18 Wrz, 17:06, Charlie Collins [EMAIL PROTECTED] wrote: GWTTestCase based tests (and GWTTestSuite, which is a great time saver) can be run by ant, yes. Ant, after all, can run the test runner the same way the junitcreator generated shell script does. Your issue is probably related to the source path or classpath. Make sure you either put your test classes in your client package, or modify the module source-path so the SOURCE (even of the tests) can be compiled by GWT. (Remember, the default GWT source path is the client package for your module.) Also, make sure the source itself, even the test source, is on the classpath.

RPC host mode fine --- RPC deployed web mode fails
Hi ... I have a (relatively) simple project that demonstrates an RPC failure that I don't know how to fix. There are two remote calls. SimpleCall returns an integer and succeeds both in host mode and in deployed web mode. ClassReturnCall returns a class instance and succeeds in host mode but _fails_ in deployed web mode. The failure message is: Class Return Call Failure: com.google.gwt.user.client.rpc.StatusCodeException: The call failed on the server; see server log for details. I built this project from scratch to show this, and haven't used or done anything exotic. I created the SimpleService and ClassReturnService using the wizards, created the .WAR file using a menu item, and deployed with a straight copy into Tomcat 5.5's application directory. The return class is defined in its own class file, is a simple bean, and implements IsSerializable. Can someone take a look at this and give some suggestions/reasons?? I don't know what to do from here. Could this be some sort of security manager problem??? Below are the log details, but the project (as simple as it is) is too much to post, so I have put it on the web: http://www.tpsoft.com/RemoteServiceTest.zip The server log says: Sep 19, 2008 6:15:31 AM org.apache.catalina.core.ApplicationContext log INFO: org.apache.webapp.balancer.BalancerFilter: init(): ruleChain: [org.apache.webapp.balancer.RuleChain: [org.apache.webapp.balancer.rules.URLStringMatchRule: Target string: News / Redirect URL: http://www.cnn.com], [org.apache.webapp.balancer.rules.RequestParameterRule: Target param name: paramName / Target param value: paramValue / Redirect URL: http://www.yahoo.com], [org.apache.webapp.balancer.rules.AcceptEverythingRule: Redirect URL: http://jakarta.apache.org]] Sep 19, 2008 6:16:11 AM org.apache.catalina.core.ApplicationContext log SEVERE: Exception while dispatching incoming RPC call java.security.AccessControlException: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks) at java.security.AccessControlContext.checkPermission(AccessControlContext.java: 323) at java.security.AccessController.checkPermission(AccessController.java: 546) at java.lang.SecurityManager.checkPermission(SecurityManager.java: 532) at java.lang.reflect.AccessibleObject.setAccessible(AccessibleObject.java: 107) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeClass(ServerSerializationStreamWriter.java: 619) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeImpl(ServerSerializationStreamWriter.java: 655) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java: 582) at com.google.gwt.user.client.rpc.impl.AbstractSerializationStreamWriter.writeObject(AbstractSerializationStreamWriter.java: 105) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter $ValueWriter$8.write(ServerSerializationStreamWriter.java:146) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeValue(ServerSerializationStreamWriter.java: 520) at com.google.gwt.user.server.rpc.RPC.encodeResponse(RPC.java:573) at com.google.gwt.user.server.rpc.RPC.encodeResponseForSuccess(RPC.java: 441) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java: 529) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java: 163) at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java: 85) at javax.servlet.http.HttpServlet.service(HttpServlet.java:709) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java: 39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java: 25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.security.SecurityUtil$1.run(SecurityUtil.java: 244) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAsPrivileged(Subject.java:517) at org.apache.catalina.security.SecurityUtil.execute(SecurityUtil.java: 276) at org.apache.catalina.security.SecurityUtil.doAsPrivilege(SecurityUtil.java: 162) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java: 262) at org.apache.catalina.core.ApplicationFilterChain.access $0(ApplicationFilterChain.java:192) at org.apache.catalina.core.ApplicationFilterChain $1.run(ApplicationFilterChain.java:171) at java.security.AccessController.doPrivileged(Native Method) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java: 167) at

Re: OnFailure getting executed even though server code does not return any errors
Ok finally I found the error.
I overrode doUnexpectedFailure method of remoteserviceservlet to find
the source of the error.
@Override

super.doUnexpectedFailure(error);
error.printStackTrace();
}
The error it displayed me was

Re: Reporting tool and GWT
We have found BIRT to be very easy to integrate as a service that is invoked by a GWT RPC call. The resultant report (we standardise on PDF) is stored on the server and may be viewed in the browser and then printed, emailed etc. BIRT also has a jsp based report viewer that may be used independently of your GWT app, although we do not use it. BIRT report design files are stored on the server and the RPC call carries the parameter(s) that may be needed to configure the report. You may also need an if (GWT.isScript()) condition to set up the path to these files when in hosted mode.

I've been mostly back-end. Anyway, I'm currently trying to find a way to define the initial width for some dropdown lists, that is narrower than the length of their longest element. However, if i click on a dropdown, is there a way to automatically resize its width to match the with its longest element?

Load Testing of GWT applications (RPC)

Unfortunately I haven't found any java API that enables to encode client requests and decode server responses. As I understant this part of GWT RPC protocol is available only in javascript. I ended up reverse engineering part of the protocol and writing an application specific python script that emulates RPC client. Is there any better approach?

Re: GWT Maps API fails on host mode
Hi Same problem here : identical stack trace and warning messages. I was working on several little testing projects in gwt/gwt-ext/ gwtmaps a month ago. Now I'm unable to launch any of them using gwtmaps in the host mode. The platform environment (OS/eclipse/jars) didn't change - same PC, none used it. Thus, if I compile and deploy these projects under my Tomcat, all is working fine. One hour ago, I tried to launch the HelloMaps from the 290 release, with the inner launch-scripts. Same results : the shell command aborts with Einstein's trace, the compiledeploy test is OK Any kind of idea would be appreciated :o) ps : I've check that my IE network/proxy settings were still good On 18 sep, 02:16, Eric Ayers [EMAIL PROTECTED] wrote: I didn't use eclipse at all.

Problem with java.lang.ClassNotFoundException only when deployed
Hi all,
First off, I am a new user and have built a very simple application.
It works fine under hosted mode. It compiles with no errors. When I
deploy it to the web server and point a browser at it, it throws a
ClassNotFoundException. I suspect this is a really simple problem
(probably caused by a really stupid error). This is driving me crazy
and I would really appreciate ANY help or suggestions anyone could
throw my way.
I have included a lot of error logs, copies of web.xml, directory
structures etc. below.
Trying to work through this is a learning experience, but I am
stumped. The fact that the server is able to sort out the URL sent
from the client enough to know the name of the object is
ca.KeithFuller.server.CorpusServiceImpl suggests to me that the server
is finding the web.xml file, which suggests that it should be able to
find the object since I believe that WEB-INF/classes is always on the
search path. The file CorpusServiceImpl.class is in WEB-INF/classes,
and the corresponding java file starts with:
package ca.KeithFuller.server;
import java.util.*; // for Scanner
import java.io.*;// for println
import ca.KeithFuller.client.CorpusSearchReturns;
import ca.KeithFuller.client.CorpusSearchService;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class CorpusServiceImpl extends RemoteServiceServlet
implements CorpusSearchService
{
...
A whole pile of details follow:
I use GWT 1.4.61
I use Eclipse 3.2.2
My webserver uses Linux, Tomcat and Apache.
I use FireFox 3.0.1 and the URL is
http://www.keithfuller.ca:9108/CorpusSearch/CorpusSearch.html
The client code contains:
...
// Create the proxy object
final CorpusSearchServiceAsync serviceProxy =
(CorpusSearchServiceAsync)
GWT.create(CorpusSearchService.class);
// Cast the proxy object to ServiceDefTarget
String serviceUrl = GWT.getModuleBaseURL() + corpus-search;
// if (GWT.isScript()){
// serviceUrl = /corpus-search;
// }
((ServiceDefTarget)serviceProxy).setServiceEntryPoint(serviceUrl);
...

Re: Annoucement. PureMVC4GWT RC is available
On 17 sep, 12:34, Luciano Broussal [EMAIL PROTECTED] wrote: Hi All, I've created a tiny but powerful gwt project The Goal is to provide a MVC framework based on the simple, well designed and powerful PureMVC framework. I didn't know PureMVC, and I'm not very familiar with MVC either (well, I know the basics but I'm far from being used to MVC), but after throwing an eye at the puremvc overview docs and at your code (loginsample and then some of the framework's classes), it seems like I was having a similar idea for the next big rewrite of our GWT app: mainly having a single object to publish/subscribe to (Facade). However, I was rather thinking about using integers (or maybe a big Enum, not the best choice as far as SoC is concerned, but easier to maintain in order to prevent conflicts) rather than strings to identify notifications (allows switch/case in Java and probably leads to faster code than String comparisons; as was done with com.google.gwt.user.client.Event's constants). All in all, PureMVC seems a little bit over-engineered, bringing too much overhead to the constrained environment that a web browser is... Looks like a good and clean pattern, but I'd rather build my own specific implementation from a template project than use this generic impl... (for example: why having a Notification class and INotification interface if you don't ever subclass/implement them? why not just have onHandleNotification(String name, Object body, String type) methods all over the place?) Actually, I didn't spend much more than half an our reading PureMVC docs and your code, so I probably missed a lot of things (btw, where's the userguide you talked about? I couldn't find it on puremvc.org, or is what's called best practices?) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT popup query, a generic one
Thanks Thomas for the reply.
Your approach works on Mozilla and IE7, but behaves weird on IE6. In
my application, I override the PopupPanel.show() method, as follows :
public void show(){
setVisible(false);
super.show();
//following logic copied from Popup.center() to show popups in
center of page
int left = (Window.getClientWidth() - getOffsetWidth()) / 2;
int top = (Window.getClientHeight() - getOffsetHeight()) / 2;
setPopupPosition(Window.getScrollLeft() + left,
Window.getScrollTop() + top);
setVisible(true);
}
As can be seen, it is required that the popup shows roughly at the
centre of viewport. Works perfect in IE7 and Mozilla, but not in IE6.
Any light in this regard ..?

Hi all.
I have been going through PopupPanel docs, and there does exist ways
to set the popup-position, eg. through the PopupPanel.PositionCallback
and setPopupPosition() methods. But it seems that the position
parameters, correspond to the entire browser window. That is, let's
say I set the left and right parameters in setPopupPosition(int
left, int right) as 0,0. Thus, the popup will be displayed on top
left.
Now, consider that my page contains records. With time, the number of
records increase, and scrollbars then come into play. Now, what is
needed that upon pressing the Delete button attached to a particular
record row, the popup should appear. As there are scrollbars, if the
record happens to be the last one (or thereabout), the popup still
appears top left of the complete browser page area, wheras ideally
it should appear on the top left of the effective browser page area
that is visible to me. (I may repeat that since there are scrollbars,
the complete browser page area IS NOT EQUAL TO effective page area,
when I am looking at one of the last records).
Any ideas/hacks/workarounds, to get this going ..??
- use Window.getScrollTop() and Window.getScrollLeft() (avec a look
at the center() method's code)

Hello everyone, I wanted to apologize for a recent bunch of spam messages that made it to the Groups discussion forum.

Re: How to tokenize a string like foo|:bar where |: is the delimiter ?
I suppose that you need to use \||: As \| - the pipe you want to split with | - OR : - the colon you want to split with Though I am not very sure on this. :) Cheers, Amit On Fri, Sep 19, 2008 at 3:58 PM, Lothar Kimmeringer [EMAIL PROTECTED]wrote: guiii schrieb: does not work.

Re: Problem with java.lang.ClassNotFoundException only when deployed
Hi Keith,
Looking at your deployment structure:
The web server has the directory structure:
apache-tomcat-5.5.25/webapps
CorpusSearch
... a pile of html, rpc, js, html, css, and...
web.xml
WEB-INF
classes
CorpusSearch.class
CorpusSearchReturns.class
CorpusSearchServiceAsync.class
CorpusSearchData.class
CorpusSearchService.class
CorpusServiceImpl.class
web.xml
lib
gwt-servlet.jar
web.xml
the package structure ca.KeithFuller.server seems to be missing which
would explain why you get a ClassNotFoundException for
ca.KeithFuller.server.CorpusServiceImpl. I think you should copy the
entire directory structure under WEB-INF\classes.
Also I would recommend you take a little time to make an Ant build
script that creates a WAR file for you application and copies it
straight to your Tomcat deployment directory where it will
automatically redeploy. This will kill problems like this (because Ant
doesn't make mistakes) and save you a lot of time in the long run.
There are lots of examples of how to do this in the group - just
search for ant build WAR.

gregor

First off, I am a new user and have built a very simple application.
It works fine under hosted mode. It compiles with no errors. When I

and I would really appreciate ANY help or suggestions anyone could

Trying to work through this is a learning experience, but I am

ca.KeithFuller.server.CorpusServiceImpl suggests to me that the server
is finding the web.xml file, which suggests that it should be able to
find the object since I believe that WEB-INF/classes is always on the
search path. The file CorpusServiceImpl.class is in WEB-INF/classes,
and the corresponding java file starts with:
package ca.KeithFuller.server;

Re: No servlet's processed when extending GWTShellServlet (Spring integration)
Hi Juan,
I'm assuming that you're trying to use the specialized
Spring-supporting subclass in hosted mode?
If that's the case, the reason why this wouldn't work is because the
embedded Tomcat instance that the hosted mode shell uses is not
configured as a Spring container. If you wanted to use hosted mode
with your Spring servlets, you would need to have these servlets
defined on your own web server, say Tomcat, that you could then use in
hosted mode by passing in the -noserver flag.
You can read more about this at the FAQ linked below:
http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=FAQ_HostedModeNoServer
Hope that helps,
-Sumit Chandel

Hi,
In short, my problem is that GWT is unable to locate the servlet
annotations in the .gwt.xml descriptor when I intercept the call to
the GWT development servlet. Except for the servlets on the
descriptor, all the GWT calls are processed without problems.
My goal is to catch some petitions to handle them using Spring while
passing the rest to the GWT development servlet. For this I extend the
GWTShellServlet as a Spring MVC adapter. As a consequence of this it's
no longer a servlet. Spring instances class that extends
GWTShellServlet, gives the ServletContext to it and I overwrite the
getServletContext() method to return it.
Here it is in short:
public class GwtDevelopmentAdapter extends GWTShellServlet implements
HandlerAdapter, ServletContextAware {
private ServletContext servletContext;
public void setServletContext( ServletContext servletContext )
{
this.servletContext = servletContext;
}
// At one point I catch the Spring method handle and redirect the
call to the GWTShellServlet
public ModelAndView handle( HttpServletRequest request,
HttpServletResponse response, Object handler ) throws Exception
{
processFileRequest( request, response );
return null;
}
}
It works without problems except when you define a servlet in
the .gwt.xml module descriptor. It just doesn't find that servlet.
The code and idea are largely based on the post
http://blog.digitalascent.com/2007/11/gwt-rpc-with-spring-2x_12.html
Any comment, suggestion, different approach would be really welcome.
Thanks in advance,
Juan

Re: CRUD
Hi Satish, This question has come up before in various guises. The answer is basically: 1) GWT is a client side AJAX toolkit - it is back end agnostic and you do not access e.g. databases directly from GWT client code 2) Instead you use asynchronous calls to your server (using e.g. GWT RPC) that return Data Transfer Objects representing views of your database schema. 3) If you use GWT RPC, then you can manage your DB transactions from your remote RPC servlets server side using e.g. JDBC. There so many different use case situations that it is unrealistic to standardize examples of this, but there are plenty of tutorial resources available on how to use JDBC around. However in a simple case you might think of it like this: a) you have a set of database tables representing your domain entities. b) you write a DTO class for each of these tables representing one row of the table (i.e. you basically have a field for each column) c) you use JDBC to execute SQL query statements in your RemoteServlets (use PreparedStatement) to instantiate DTO's which you then return to your GWT client over RPC and you populate your widgets with the values of these DTO's. d) on the client side when you need to create/update and save a new/ changed entity instance, you strip vlaues from your UI widgets to create a new DTO instance for the entity and dispatch this DTO to the server over RPC for storage e) you use then JDBC to execute SQL update statements in a remote servlet using the values from this DTO. This is of course likely to be an over-simplification, but it is the basis of a typical approach for connecting a GWT client to a back end database resource. regards gregor On Sep 18, 10:15 am, satish [EMAIL PROTECTED] wrote: hi am new to this GWT is there any ready to run examples on CRUD in this gwt using derby as backend if yes please provide me any suggestions would be helpful for me thankhs --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: questions on Login Security FAQ
Reinier,
Thanks for the additional input. Can I get some more clarification
from you though?
First of all, I don't understand your (A) response. I said you
don't need to worry so much about passing session IDs since the app
server will pretty much handle that for you... and your response
seems to just reiterate what I said - but you stated it in a manner as
though you were disagreeing with me. I don't get it.
Secondly, BCrypt is not mentioned in the original author's post at
all, nor does it seem to be mentioned in the linked guide to
security. I was not intending to write an all encompassing guide here
but perhaps I should have been a little more clear. I said in
addition to what others have said and regardless of which hash
algorithm. Put those two together and this was meant to be taken
as: it doesn't hurt to concatenate the username+password+some-other-
string on hashed passwords stored in the DB, regardless of algorithm.
Why? Because if you happen to be using a weak algorithm or even a
strong one for which a weakness is later discovered, you are better
off with a concatenated string than just storing the passwords as
is... especially for brute force attacks targeting weak password
strings such as the word password or secret. So I was stating
that I prefer to do this than to put all my trust just in the
algorithm. By no means was I advocating to make up your own security
- I said in addition to what others have said... and by that I mean,
if BCrypt is the latest and greatest, then by all means - use it.
Just remember, there was a time when DES was considered the ultimate
encryption algorithm. A time could come when BCrypt was as well.
I find the best best practices advice described in timeless generic
terms - without specifying the names of algorithms or 3rd party
libraries. So my question to you is, could you please restate some
useful advice or a best practice in such a manner?
Thanks,
J

feel too insulted, you're like almost everyone else out there.
However, you should most definitely stop handing out security advice.
Seriously.
A) J2EE doesn't magically work without session keys. It just handles
them for you; they are still stuck in a cookie someplace. HTTP is
stateless. A session is by necessity involved.
B) BCrypt (and you should use BCrypt, or you Fail Security. Seriously.
Don't think about it, you failed the test. Use tools written by the
experts) - is a better take on a technique called 'salt hashing',
invented a few decades ago. With salt hashing, two people with the
same password do not have the same hash in the database. The fact that
you don't even know the principle of salt hashing means you're a few
decades behind the times.
C) You don't check HASH(username+password), because BCrypting 'abc123'
and BCrypting 'abc123' again does NOT result in the same hash value!
That's the whole point. You BCrypt('abc123') exactly once, and then
later, you get the hash from the db and ask BCrypt to verify that
'abc123' was used to generate that hash. Even if you somehow solved
this problem (by removing the salting from the equation which is very
stupid), then there's still the birthday paradox (wikipedia that) to
ensure that there are actual serious odds of a collision. In case of a
collision, some random user will log in as someone else, or if you add
a unique constraint, some user will someday pick/change his password
and get a persistent server error. Big whoops.

Hi Cresteb,
I have a couple of things to add to what others have said.
1 - I presume all of the session talk in this thread is in regards to
non-Java languages for the server-side. If you are using a J2EE
application on the back end you don't need to worry so much about
passing session IDs since the app server will pretty much handle that
for you once authentication has been established. In fact, you are
encouraged not to.
2 - When generating a password hash to store in a DB, regardless of
what hash algorithm is used I will typically hash the (username
+password) and place that in the password field. This offers a couple
of advantages. a) you get a single ticket by which a user can be
looked up if both values are known. b) if your data gets compromised,
even the passwords of users who stupidly use the same common password
(i.e. password, secret, etc...) won't show up the same in the
database. To make it even better you can add another element to the
mix (secret+username+password) so that the same username+password in
different applications shows up differently in the database.

Re: SerializationException error
Thanks Wanden for your attention! It's look like non-trivial way! Sorry but I don´t explain the solution completely. I use only Session Beans to implents bussiness logic and transaction context and persistence with Hibernate. In this case the solution is the same? Do you no about one application with the same architecture? I was thinking about change my project. May be implements a middleware broker to communicate with services under XML. What do you think about this solution? Have you another idea? Thanks Flávio 2008/9/19 walden [EMAIL PROTECTED] Yes, but it's not trivial. First, you need to construct a gwt module around the ejb classes you intent to share with the client. This involves placing a ejbname.gwt.xml file someplace in the folder structure above all those classes, and then using the source tags to point to all the places where ejb sources live. This can sometimes force you to reorganize folders a little. None of this will work unless you are on GWT-1.5, by the way. Next you need to see why the GWT compiler fails to compile your ejb sources. This is about dependencies that go outside your module and outside the GWT runtime emulation footprint. You'll have to rip all that out (and figure out how to live without it). Finally, you will have to deal with runtime serialization problems wherein the JPA has replaced Java collections objects in your entities with its own persistence lazy load variants, which are not known to GWT and cannot be known to GWT and therefore cannot serialize.

Re: gwt functionality to jsp page
I agree that hijacking JSP pages and wrapping elements with GWT widgets is not the best long-term approach. As an alternative to using JSNI to hijack the drop-downs, you could make the host JSP page simply contain empty placeholder div elements with known id values, insert your GWT ListBox instances in them using RootPanel. You could populate the list options with server data gotten via separate request (GWT RPC?). While it's true that this is an extra round-trip, you have to look at it in the overall context of developing a rich client, in which case you may already have need to fetch data from the server, and you could piggyback this request onto that. This approach has the added benefit that if the list box contents are at all dynamic, you now have the means to refresh them.

Re: SerializationException error
Flavio, The solution is essentially the same. I had assumed the classes you want to serialize are EntityBeans, but it sounds like they are Hibernate POJOs, but it's almost the same thing. The classes need to be moduled up and put on the GWT compiler classpath, they have to be clean with respect to JRE emulation, and since they are Hibernate objects, you will still have the lazy load proxy objects in there to contend with. I think rolling your own XML serialization of these objects is a nightmare, don't do that. Walden On Sep 19, 10:03 am, flavio faria [EMAIL PROTECTED] wrote: Thanks Wanden for your attention!

the package structure ca.KeithFuller.server seems to be missing which
would explain why you get a ClassNotFoundException for
ca.KeithFuller.server.CorpusServiceImpl. I think you should copy the
entire directory structure under WEB-INF\classes.
Also I would recommend you take a little time to make an Ant build
script that creates a WAR file for you application and copies it
straight to your Tomcat deployment directory where it will
automatically redeploy. This will kill problems like this (because Ant
doesn't make mistakes) and save you a lot of time in the long run.
There are lots of examples of how to do this in the group - just
search for ant build WAR.

It works fine under hosted mode. It compiles with no errors. When I

and I would really appreciate ANY help or suggestions anyone could

I have included a lot of error logs, copies of web.xml, directory

Trying to work through this is a learning experience, but I am
stumped. The fact that the server is able to sort out the URL sent
from the client enough to know the name of the object is
ca.KeithFuller.server.CorpusServiceImpl suggests to me that the server
is finding the web.xml file, which suggests that it should be able to
find the object since I believe that WEB-INF/classes is always on the
search path. The file CorpusServiceImpl.class is in WEB-INF/classes,
and the corresponding java file starts with:

Re: PopupListener
The center() method calls hide() which triggers the onPopupClosed.
I had this problem, but since I couldn't believe it hadn't been noticed in
testing before release, I assumed there must be a good reason for it, or
that *not* doing it means I had been following some evil coding practice.
Again.

I have noticed that the Popup has changed from 1.4 to 1.5
In 1.4 I could write
Popup popup = new Popup();
popup.addPopupListener(new PopupListener()
{
public void onPopupClosed(PopupPanel sender, boolean autoClosed)
{
Window.alert(HI);
}
});
popup.show();
and it would work
In 1.5 if I write it this way the onPopupClosed fires before the popup
shows. It will fire when I close the popup too late by now.
Is this now the new rule add the listener after the show or center
method is called.

Strange GWT / Prototype interaction on Safari???
Greetings, I'm seeing a strange situation using Prototip (a Prototype based tool- tip package) with GWT - only on Safari. Here's the setup: - both prototype.js and prototip.js included from my .gwt.xml file - jsni native call to new $win.Tip(...) to create the tooltip Works swell on Firefox, IE, Chrome - but throws an exception on Safari that observe is not defined. I've stuck the following bit of JS code into my native method to see: var test = $doc.createElement(div); $wnd.alert(test + .observe = + test.observe); Lo and behold, on FF, IE, Chrome, the alert box comes up saying that the div element has an observe method defined, but in Safari it says undefined. This observe method is a method added as part of the Protoype bootstrapping. I've added alerts to the prototype library to ensure it's bootstrapping and is surely is. I can't recreate this in hand-coded html - so it seems like some interaction with GWT? Can anyone enlighten me on this?

Re: Annoucement. PureMVC4GWT RC is available
Hi, Here is the documentation http://puremvc.org/component/option,com_wrapper/Itemid,174/. It is available on the PureMVC Home page. Maybe you don't like but i'm not sure you can do more simple than the 15 classes which compose PureMvc and help the developper to separate layers and the main design patterns it use : Proxy Facade. Medialor Commands View Controller Anyway, thank you for had a look to the project.

However, I was rather thinking about using integers (or maybe a big Enum, not the best choice as far as SoC is concerned, but easier to maintain in order to prevent conflicts) rather than strings to identify notifications (allows switch/case in Java and probably leads to faster code than String comparisons; as was done with com.google.gwt.user.client.Event's constants). All in all, PureMVC seems a little bit over-engineered, bringing too much overhead to the constrained environment that a web browser is... Looks like a good and clean pattern, but I'd rather build my own specific implementation from a template project than use this generic impl... (for example: why having a Notification class and INotification interface if you don't ever subclass/implement them? why not just have onHandleNotification(String name, Object body, String type) methods all over the place?) Actually, I didn't spend much more than half an our reading PureMVC docs and your code, so I probably missed a lot of things (btw, where's the userguide you talked about?

Communicating between php and GWT using JSON
Hi All,
I am trying to communicate between php and GWT, for which I have tried and
successfully used JSON, using the following code
if(!HTTPRequest.asyncGet(http://myurl/index.php;, new
JSONResponseTextHandler())) {
Window.alert(Error accessing index1.php);
}
Now I want to transfer data back to php from GWT. What is the right
procedure for this?
Further, is JSON a safe and the industry standard method of communicating???
Or shall I consider XML or something else...
Thanks in advance... :)

Re: Communicating between php and GWT using JSON
HTTPRequest is deprecated, you should consider using RequestBuilder
JSON is fine for trusted sources, and the parsing (de-serializing) is
actually pretty instantaneous if you use the JS Overlay techniques
(direct evaluation) available in GWT 1.5.
Of course, if you are getting JSON from a non-trusted source, you'll
want to be considerably more cautious about your parsing.

Re: RPC host mode fine --- RPC deployed web mode fails
Good call, Lothar -- I changed my private declarations to public and put an ominous looking comment next to each of them. Once I did that, the serialization worked fine ... both on my test case and my much larger application. I also tried setting security permissions for the security manager in Tomcat's policy file. That was a disaster ... I'll have to get with someone who knows Java Security Manager better. Thanks!

Re: iPhone toggle switch implementation
That's not how stylesheets work.
You have two options:
A) change the style of a given element. e.g. use add/removeStyleName,
to change the styling info of your widget. for example:
myWidget.setStyleName(someStyleClassThatIsAlwaysApplied);
if ( toggledOn ) {
myWidget.removeStyleName(toggledOn);
myWidget.addStyleName(toggledOff);
} else { /* you can guess what goes here */ }
B) Have two widgets, one for each 'toggle', and alternatively hide/
show them. Use the widget's .setVisibility(bool) method to do it.

Re: questions on Login Security FAQ
I don't know jasypt, so I can't make guarantees (actually, nobody can, but you know what I mean). However, there are two good signs: 1) The API is specifically for password checking. This is a lot better than using a generic hasher and doing the salting yourself. The authors of the library had password hashing in mind when they wrote it. If they did their job right, it should be good for password hashing. 2) The API call is checkPassword(thePassword, theHash). This is the 'right' form of such a library. Contrast to e.g. hash(thePassword).equals(theHashFromTheDB), which is the -wrong- form (because there's no salt in that mix at all), or even hash(saltFromDB +thePassword).equals(hashFromDB), which is probably okay, but requires more acts on behalf of the library user, including generating a cryptographically secure salt somehow. So, that very shallow review says: It's all good. But no guarantees on the jasypt author's security chops.

I don't get it. From a security point of view, which is what this thread is about, who does the sessionid passing is mostly immaterial. It should also be noted that the first servlet engine for tomcat started the boneheaded 'sessionid in the URL' security fart, so the userbase size of a j2ee container is no guarantee that the security is sorted out properly. Secondly, BCrypt is not mentioned in the original author's post at all, nor does it seem to be mentioned in the linked guide to security. Huh? (j)BCrypt is the first link mentioned on the LoginSecurityFAQ. I didn't just add that - that's been there since I posted the second draft, a long long time ago. It wasn't mentioned in the original author's post, which is exactly why *I* mentioned it. BCrypt is a fantastic idea. You should be using it when storing passwords in a database. I was not intending to write an all encompassing guide here but perhaps I should have been a little more clear. I said in addition to what others have said and regardless of which hash algorithm. Put those two together and this was meant to be taken as: it doesn't hurt to concatenate the username+password+some-other- string on hashed passwords stored in the DB, regardless of algorithm. No - you don't get it, evidently. 1) You -cant- query the database for HASH(username+password), because if that worked, you by definition have really bad saltless hashing. So what's the point, then? Why store the username as well? You're just making it harder to rename usernames (bad), and... 2) You risk collisions. Assuming that the idea is that this username +password combo is somehow a unique key, collisions can happen, and that's no good. But mostly: 3) my advice is: Use BCrypt. Your advice is: hash on username+password instead of just password, which is much worse than listening to me. Your point is basically: If you forget to listen to any (good) advice, then listen to MY advice. This makes no sense; the premise was already: Programmer did not listen to ANY advice. We've got three options here: A) Programmer doesn't listen to advice. Okay. We can chat here until the end of days, but he's not listening. Shame, but, we can't stop him. B) Programmer listens to the only advice that mattered: He uses BCrypt. Peachy. Your advice is now irrelevant and in fact slightly bad: He just lost the ability to rename his username and needs the username in his check routine which clutters his parameter lists. C) Programmer wanted to listen to advice but the chatter is starting to confuse him, and he turns into #A: He stops reading and just goes his own way, most likely doing it very wrong. This is important, as java tends to suffer a lot form this principle: Don't overwhelm people with 15 answers. Just give the best answer, and if that particular answer doesn't fit the asker's needs, let him get back to you about that. Don't throw half a book at him, especially if most of the advice in it is pretty much irrelevant or useless. That's another very good reason why you shouldn't mention your username+password hashing scheme. It doesn't add anything useful to the discussion: Either the user is doing his salt/hashing correctly, and your scheme doesn't add anything, or he's not doing it correctly, and your scheme adds very very little. Why? Because if you happen to be using a weak algorithm or even a strong one for which a weakness is later discovered, you are better off Just to set you straight on this one: If BCrypt's salt/hash concept is somehow broken, then a username+password hash is equally or even worse broken; BCrypt already uses different source material for the same passwords by different users. This is like screwing a highschool locker padlock on a $10,000 dollar safe door. If someone is going to get access to the safe's contents, you can be certain the padlock didn't stop the criminal for even a second. He either bypassed the lock entirely, or he got the code from someone, or he actually can pick locks; and if he can pick a safe, he can open that padlock in an instant. In the mean time, the padlock, which has added absolutely no value to your security setup, IS annoying you everytime you want access to the safe. Hence, just get rid of the bloody thing, it's making it harder for you in operation, and its making it harder for a security analyst because it obscures the true protection measures with irrelevancy. A time could come when BCrypt was as well. Again, your scheme adds nothing. Stop confusing people with fearmongering talk about BCrypt someday failing. DES never failed; it's just

Re: iPhone toggle switch implementation
Reinier,
Thanks for the help. I've been also thinking of creating my own
images and then just using ToglleButton.

That's not how stylesheets work.
You have two options:
A) change the style of a given element. e.g. use add/removeStyleName,
to change the styling info of your widget. for example:
myWidget.setStyleName(someStyleClassThatIsAlwaysApplied);
if ( toggledOn ) {
myWidget.removeStyleName(toggledOn);
myWidget.addStyleName(toggledOff);
} else { /* you can guess what goes here */ }
B) Have two widgets, one for each 'toggle', and alternatively hide/
show them. Use the widget's .setVisibility(bool) method to do it.

div class=toggle onclick= toggled=truespan
class=thumb/spanspan class=toggleOnON/spanspan
class=toggleOffOFF/span/div

I assume I can use a HorizontalPanel and setStyleName(row) and then
add a button with style toggle but how do I send the toggled=true
info to the CSS and add the 3 span elements?
Thanks in advance

Exception: This widget's parent does not implement HasWidgets
Hi!
I'm trying to make my class MenuHome as a container through the
abstract class com.google.gwt.user.client.ui.Composite.java but I
have always the same problem:
This widget's parent does not implement HasWidgets.
In the main class I want a panel that could contain all the widget
children (instances of other classes) and then be able to remove any
time a widget you do not have to see, perhaps with a command
vPanel2.clean()
When run my application, when I click on LOGIN shows this exception.
How could solve?
My code simplified:
-MenuHome.java---container
import com.google.gwt.user.client.Command;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.MenuBar;
import com.google.gwt.user.client.ui.VerticalPanel;
public class MenuHome extends Composite {
private VerticalPanel vPanel;
private Login login;
public VerticalPanel vPanel2;
public MenuHome() {
super();
Command cmd = new Command(){
public void execute(){
vPanel2.clear();
}
};
Command cmdOpen = new Command(){
public void execute(){
if(vPanel2.getWidgetCount() == 0){
login = new Login();
vPanel2.add(login);
}
}
};
vPanel = new VerticalPanel();
MenuBar menu = new MenuBar();
vPanel2 = new VerticalPanel();
menu.addItem(HOME, cmd);
menu.addItem(LOGIN, cmdOpen);
vPanel.add(menu);
vPanel.add(vPanel2);
initWidget(vPanel);
}
protected void onAttach() {
super.onAttach();
}
}

import com.google.gwt.user.client.ui.VerticalPanel;

import com.gwtext.client.widgets.Button;
public class Login extends Composite{
MenuHome mhome = new MenuHome();
private VerticalPanel panelVert;
private Button loginButton;
public Login(){
panelVert = new VerticalPanel();
panelVert.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
panelVert.setVerticalAlignment(HasVerticalAlignment.ALIGN_MIDDLE);
loginButton = new Button(Login);
panelVert.add(loginButton);
initWidget(panelVert);
mhome.vPanel2.add(panelVert); //-the error add
