Re: how to proxy all the methods in my RemoteServiceServlet
Hi, If you don't want to give a try with Spring( or Guice), you could use AspectJ to weave your desired behaviour (handling security).

Re: GWT Timers - say no to it with IE
Right, sorry that I haven't posted code before.
And the broblem is actually not in timers, because I temporarily
removed them,
there's smth else.
Here is the code:
// file ChartItem.java
public class ChartItem extends AbsolutePanel implements
ChartItemChanger {
private PopupMenu pp = PopupMenu.getInstance();
private ChangeListener mouseOverListener, mouseOutListener,
mouseOnClickListener,mouseOnMouseDownListener,
mouseOnMouseUpListener;
public ChartItem () {
sinkEvents(Event.MOUSEEVENTS);
setMouseListeners();
}
private void setMouseListeners() {
mouseOnClickListener = new ChangeListener() {/* This
is the place where IE does not respond*/
public void onChange(final Widget wdgt) {
/* Sending link to an interface */
pp.setChartItemInterface(ChartItem.this);
/* Calling standard methods of PopupPanel
class*/
pp.setPopupPosition(getAbsoluteLeft(),
getAbsoluteTop() );
pp.show();
}
};
mouseOnMouseDownListener = new ChangeListener() {...}
mouseOnMouseUpListener = new ChangeListener() {...};
mouseOverListener = new ChangeListener() {...};
mouseOutListener = new ChangeListener() {...};
}
public void onBrowserEvent(Event event) {
super.onBrowserEvent(event);
int type = DOM.eventGetType(event);
switch (type) {
case Event.ONCLICK:
mouseOnClickListener.onChange(this);
break;
...
}
}
}
//
// file PopupMenu.java
/* A singleton class */
final public class PopupMenu extends PopupPanel {
private static PopupMenu INSTANCE;
private ChartItemChanger changer;
public static PopupMenu getInstance() {
if (INSTANCE == null) {
INSTANCE = new PopupMenu();
}
return INSTANCE;
}
private PopupMenu() {
super(true);
...
}
void setChartItemInterface(ChartItemChanger changer) {
this.changer = changer;
}
@Override
public void show()
{ if (Flags.ALLOW_POPUP_MENU_SHOWING)
super.show();
}
}
// file Flags.java
public class Flags {
boolean ALLOW_POPUP_MENU_SHOWING=true;
...
}
ChartItem also contains an image and when user clicks on it PopupMenu
should be shown.
It is ok in FF, but not in IE.

The W in GWT is for "Web", which precludes access to the "desktop". You can however use GWT to create an Adobe AIR application (eventually using the GWT-in-the-AIR project, but not necessarily: you can also use JSNI for your AIR API calls), which will have access to "desktop features" such as accessing the file-system. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: redirect problem
For GWT RPC and Spring integration, you may first look at the GWT Server Library http://gwt-widget.sourceforge.net/ . The GWT-SL provides a GWTHandler to handle the GWT RPC request and then invoke the corresponding service POJO. The configuration is rather standard and straight forward. To intercept the call between the GWT-SL GWTHandler and the POJO service, you can look at the Spring AOP, eg, BeanNameAutoProxyCreator ... sth like that.

What if you set a ClickListener on the Image?

Re: GWT Spring && Spring Security (ex acegi).
Hi, For the "my" GWT Dispatcher you don't need extra xml configuration to map the GWTHandler to the Managed bean: * the Spring configuration (application context) is unaware on the GWT-RPC underlying. * very simpler to maintain. This DispatchServlet resolve the Managed Bean that implements the RemoteService invoked without any configuration in your applicationContext.

Hosted mode ServletContextProxy not available in javax.servlet.Filter
Hi all, I've encountered a problem with the resolution of the Serialization file in hosted mode, because the shell servlet uses a ServletContextProxy which is not available in the a javax.servlet.Filter. My work around in hosted mode is to ask this resources (IUZIUZUI.gwt.rpc) to the shell servlet using an HTTP request (it's not very efficient, but in hosted mode in not a big deal).

Weird problem with shared code
Hello everybody, I have encountered a very weird problem with shared
code between client and server.
The client is GWT compatible Java code and the server is pure Java.
We have created a serializable class, Request (public class Request
implements IsSerializable) which we want to use to exchange data
between client and server code. The class was included in the .rpc
file generated by the compiler, so it's indeed serializable. Moreover,
inside this class we have a method that sets the object for this
request; inside this method, an encoding protocol is obtained via
object's class name (if this is a list, we typecast it to List and get
the first element's class name - if the size is != 0). The code for
all protocols is compatible with GWT, since it compiles successfully,
the request object arrives at the servlet and the response back.
However, writing any of the following lines of code has no effect:
request.setObject (o)
or
request.getObject ()
It acts as if they don't exist, in either client/server code. I have
print-lined before and after the request in servlet, and all prints
BEFORE the request sets a list of objects work, BUT all after DON'T;
this would indicate that setting an object is a problem, BUT then, the
function exists successfully, since client code receives the request.
You would ask 'if you get a new request back, what's the problem?'
The problem is handling this request, since I have agents that handle
the object inside this request,
so ... request.getObject () - again, something breaks, because I used
Window.alert("...") just before getting the object and again one just
after. The second one doesn't get executed, but no errors, no
exceptions!!
I should mention that hosted mode works just fine and I am able to
display the object (so it's handled correctly).
Is there any problem if I use a shared package/classes (within same
project) for both client and server code? How would I detect this
problem since I don't get any errors?
Sorry for the long post, I hope you have the patience to read it :)

colorating a tab
Hi folks,
I'm new to GWT (but I read the tutorial). I need to give my tabs a
different color, and this is what I see in my firebug:
.gwt-TabBar .gwt-TabBarItem {standard.css (line 870)
background:#D0E4F6 none repeat scroll 0%;
color:black;
cursor:pointer;
font-weight:bold;
margin-left:6px;
padding:3px 6px;
text-align:center;
}
.gwt-TabBar-Into .gwt-TabBarItem {main.css (line 55)
background:#EE none repeat scroll 0%;
color:#6F6F6F;
}
so the standard css background and color are overriding my locally
defined attrs in main.css.
Is it due to a bad configuration? or is it the way it is supposed to
work?
I added a style to the tab bar:
mainTabPanel.getTabBar().addStyleDependentName("Into");
But this doesn't affect each tab (I was also expeting a method such as
addChildrenStyleDependentName() )...
The only solution I found is to call setStylePrimaryName() and copy
all subsequent styles : for the tabbar, the bar, the items... from
standard.css changing only the colors: I don't think GWT was designed
this way...
Anyway, any help is very welcome.
Regards,
Zied Hamdi

Re: Severe performance problem after upgrading to GWT 1.5.2 (final)
Hi Manuel, It seems hbatista's slowdown in performance was related to a database change. In your case, are you still experiencing slowdowns on your RPC calls? Also, did these slowdowns occur when you went from 1.4.x to 1.5.2, or were you always facing slow RPC calls in your GWT application?

Re: GWT Menu Active Item Hightlighted
Hi Sumit, Thank you so much for getting back to me. The hovering works just fine. When hover over the menu item the class changes to gwt-MenuItem-selected. But when an actual item is selected, the class/id does not change. So I'm not sure how to change the class so that I can give it specific style. I'd really appreciate it if you could help.

Re: colorating a tab
GWT has default styles for all its widgets. For example, Button class has the style .gwt-Button. The same applies for other widgets, including more complex ones. What you see in firebug, .gwt-TabBar is the default style for TabBar, and .gwtTabBarItem (the next style on the same line) is the style for TabBarItem which is furthermore cascaded (derived) from .gwtTabBar. When you don't set any styles for a widget, it uses its default style (and further, cascades the style for complex widgets). You said the code overwrote your styles defined in main.css, this is because you don't have the required styles names in your CSS file (main.css). Otherwise, GWT would load the styles from your file. If you want other names for your styles, just define them and use setPrimaryStyleName (...). Furthermore (let's say you have a generic setting for a widget and you want further customization for a specific one), use setStyleDependentName (...). To finish, I haven't checked the following case: if I set a style name, let's say "shyStyle" for a TabBar, I don't know if GWT knows the styles for subitems, like ".shyStyle .getTabBarItem" Hope it helps, cheers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

No, beacuse the classes don't exist inside the compiled
Javascript-result. If the values are coming from the
server-side, you can format them there by adding a
parameter "locale" to the list of parameters of the
method:
public MyDataResult getServerStatus(String locale){
MyDataResult res = new MyDataResult();
res.startDate = getServerStatus().getStartDate();
Locale l = getLocale();
DateFormat formatter =
SimpleDateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.MEDIUM, l);
res.startDateFormatted = formatter.format(res.startDate);
return res;
}
private Locale getLocale(String locale){
StringTokenizer tt = new StringTokenizer(locale, "_");
Locale loc = new Locale(tt.nextToken(), tt.hasMoreTokens() ? tt.nextToken() :
"", tt.hasMoreTokens() ? tt.nextToken() : "");
return loc;
}
The locale passed to the servlet can be read using JSNI (I don't
know if there is a way to get it via GWT already) or the servlet
reads in the corresponding HTTP-request-header (then you can
leave away the parameter or you use it as default if the parameter
is null).

any plans to offer java bean support in future?
Hi All, I've been using a 3rd party wysiwyg tool to create my gwt interface, and one thing I've run into is that gwt does not support java bean type customization. The following was suggested: "General JavaBean support would be good which would include standardize support for property accessors, default constructors, custom editors, customizers, Beans.isDesignTime(), etc." see: http://www.instantiations.com/forum/viewtopic.php?f=11&t=2174&sid=301959ff86789c33cea2e71c1b58da83 The thing that I would need is custom editors. Would there be any plans in the future to support this kind of thing?

Re: Weird problem with shared code
Hi,
Since GWT 1.4, IsSerializable is not necessary, Serializable is enough.
1:) AFAIK the Type must be known at compile time so setObject(Object o) is
out !
You should have a base Serializable class (know at compile time)
2:) The JavaBean contract must be honored : That getThat / setThat(That
that).

Re: how to proxy all the methods in my RemoteServiceServlet

By looking into RemoteServiceServlet I see a couple of ways
that should be possible (I haven't tried, so I might be
wrong ;-)
/**
* Override this method to examine the serialized version of the request
* payload before it is deserialized into objects. The default implementation
* does nothing and need not be called by subclasses.
*/
protected void onBeforeRequestDeserialized(String serializedRequest);
Overwriting this method allow you to throw the NotLoggedInException
for every method that is going to be called.
If you want to throw the execption only for a list of methods
(e.g. to allow the login without creating a second servlet),
you might overwrite processCall instead. Here an example of how I
think it should be possible:
public String processCall(String payload) throws SerializationException{
try {
RPCRequest rpcRequest = RPC.decodeRequest(payload, this.getClass(), this);
if (!rpcRequest.getMethod().getName().equals("checkLogin")){
if (!isValidSession){
throw new NotLoggedInException();
}
}
}
catch(SerializationException se){
throw se;
}
catch(Exception e){}
return super.processCall(payload);
}
NotLoggedInException must be derived from SerializableException

Above should be usable in an abstract way, you can define the
list of allowed methods by using e.g. annotations or a list
of strings being set in the init-method of the derived servlets.
The only thing missing is a class implemeting AsyncCallback that
overwrites onFailure and checks for the NotLoggedInException to
"redirect" to the login-panel automatically.

How is the main.css included? It might be a "priority" problem: if
main.css is loaded before standard.css (which will probably be the
case if main.css is not GWT-injected with a in your
module's gwt.xml), given that the two selectors have the same
"specificity" [1], their rules are evaluated in the order they've been
loaded, so the background and color set in standard.css will override
the one set in your main.css.
Try adding an "!important" to your rules and see if they're applied
(with !important, the rules in standard.css won't override your own !
important rules, even though they are evaluated after them).
If that's the case, try to find a way for your stylesheet to be loaded
after standard.css (and remove the !important, which is bad practice
and recommended for user-stylesheets only [2]), either by getting your
main.css injected by GWT, or by inheriting StandardResources (instead
of Standard) and calling the standard.css by yourself...
If I were you however, I'd file a bug to have the injected stylesheet
come *before* the existing ones so that the ones already present in
the page override the injected stylesheets...

As Lothar said: no.
However, JavaScript's Date object has some handy methods:
toLocaleString(), toLocaleDateString() and toLocaleTimeString(), so
you could use JSNI to get the javascript Date used by the
java.util.Date emulation and call the toLocaleDateString or
toLocaleTimeString on it (java.util.Date::toLocaleString() already
maps to javascript's Date.prototype.toLocaleString):
public static native String toLocaleDateString(Date d) /*-{
return d.jsdate.toLocaleDateString();
}-*/;
You'd have to use some GWT.isScript()-protected code for the hosted-
mode (see below); and I don't know to what extent those methods are
supported in browsers... (they seem to be supported in Firefox and
IE6+ at least, so it shouldn't be a problem using them).
public static String toLocaleDateString(Date d) {
if (GWT.isScript()) {
return nativeToLocaleDateString(d);
} else {
// put your hosted-mode "pure Java" code here
}
}
private static native String nativeToLocaleDateString(Date d) /*-{
return d.jsdate.toLocaleDateString();
}-*/;
...note that this means too that you're quite limited in the formats
you can use...

Re: how to proxy all the methods in my RemoteServiceServlet
that doesn't work. I have tried that. If you throw an Exception in
onBeforeRequestDeserialized, the Exception never gets translated into
the GWT protocol as that code is lower down the stack and instead GWT
receives an InvocationException and doesn't know what happened.
overriding processCall is to high up and you get no translation
either.
To do what you are suggested, a new method in RPC called invokeMethod
would need to be created like so
(these two lines from RPC.java invokeAndEncodeResponse)
Object result = serviceMethod.invoke(target, args);
responsePayload = encodeResponseForSuccess(serviceMethod,
result,
serializationPolicy);
invokeAndEncodeResponse method would call that new method and I could
override that and then GWT would be translating the exception
correctly for me, BUT GWT does not have this. I have submitted this
change years ago but to no avail as I would LOVE to override that
method.I guess spring is the only way if only I can get some
example code.

Re: how to proxy all the methods in my RemoteServiceServlet
http://code.google.com/p/net-orcades-spring/ It's dispatching your GWT-RPC. Provides security including authentication && authorization around GWT service. There also some test to build some widget that can activate / deactivate when user login / logout. There is a sample as Featured download. Regards.

Re: Weird problem with shared code
The type must be known for instanced objects, not generic object
passing to methods.
In GWT, I can't do the following:
Object o = new Object ();
Instead, I can do this:
Object o = new ListBox (false); (altough I surely would typecast again
to ListBox so that I can do something with that object).
What is that thing about honoring JavaBean? :)
I don't know how, but we have solved the problem, but just by
coincidence. Up until now, I couldn't find a reasonable explanation
for what happened or what the problem was.

Sure, but if you write such code *only* on server side, the code will
compile, but GWT serialization won't works as "ListBox" (not a good example
...) will be unknown at GWT compile time.

Label + Hyperlink + Label
I'm wondering if this is really the best approach, of it I'm one widget short of a better idea. I'm just trying to write some text, a gwt Hyperlink, and more text. Basically trying to concatenate labels and Hyperlinks. I can do this by creating a HorizontalPanel, adding the label, then adding the Hyperlink, then adding more labels, more Hyperlinks, and so on. But is it really necessary for the HorizontalPanel to be there? Is there something else that would be better? Just off hand, I thought of things like taking the Hyperlink's .getHTML() and concatenating that with the label's text, but that isn't what I'm after.

Re: Safe to make *ServiceAsync a singleton?
I think it's reasonable to have a single instance of a *ServiceAsync, but I wouldn't put it into a singleton. As Miško Hevery puts it, "Singletons are Pathological Liars". Check out this blog post for why: http://googletesting.blogspot.com/2008/08/by-miko-hevery-so-you-join-new-project.html You'd be better off injecting the *ServiceAsync into objects that need it. However, as Essington pointed out, you might need to figure out a way to lazy load these *ServiceAsync if you have a lot of them.

By looking into RemoteServiceServlet I see a couple of ways
that should be possible (I haven't tried, so I might be
wrong ;-)
/**
* Override this method to examine the serialized version of the request
* payload before it is deserialized into objects. The default implementation
* does nothing and need not be called by subclasses.
*/
protected void onBeforeRequestDeserialized(String serializedRequest);
Overwriting this method allow you to throw the NotLoggedInException
for every method that is going to be called.
If you want to throw the execption only for a list of methods
(e.g. to allow the login without creating a second servlet),
you might overwrite processCall instead. Here an example of how I
think it should be possible:
public String processCall(String payload) throws SerializationException{
try {
RPCRequest rpcRequest = RPC.decodeRequest(payload, this.getClass(), this);
if (!rpcRequest.getMethod().getName().equals("checkLogin")){
if (!isValidSession){
throw new NotLoggedInException();
}
}
}
catch(SerializationException se){
throw se;
}
catch(Exception e){}
return super.processCall(payload);
}
NotLoggedInException must be derived from SerializableException

Above should be usable in an abstract way, you can define the
list of allowed methods by using e.g. annotations or a list
of strings being set in the init-method of the derived servlets.
The only thing missing is a class implemeting AsyncCallback that
overwrites onFailure and checks for the NotLoggedInException to
"redirect" to the login-panel automatically.

Re: Label + Hyperlink + Label
Tricky, but doesn't quite work in my attempts.
Both HTMLPanel.add() and HTMLPanel.addAndReplaceElement() puts a
newline before the link, so I end up with:
blah blah
link
blah blah
instead of: blah blah link blah blah
I'm putting the HTMLPanel in a FlexTable's cell.

Multiple *.gwt.xml in One Module
Hi, I was following Solution #6 (Drag and Drop) example from the book "Google Web Toolkit Solutions: More Cool & Useful Stuff". I used Intellij 7 with GWT 1.5 to compile the example but failed with the errors reported. I tried a few things unsuccessfully and finally I removed the line from /com/ gwtsolutions/DragAndDrop.gwt.xml (included below) and everything went smoothly. My question is, should this line be removed since we already inherited Components with this directive in the previous line? Both com.gwtsolutions.components.client.ui.Dnd and com.gwtsolutions.components.Components are in the same module where Dnd.gwt.xml is 2 level down drom Components.gwt.xml. Is it possible to have 2 gwt.xml files in 1 module? Thanks /lim/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

It has nothing to do with the HTMLPanel actually, but a problem with
the Hyperlink widget: it's made up of a DIV wrapping an A, that's this
DIV wrapper that's causing the line breaks, because a DIV is
display:block by default.
I'd suggest replacing the Hyperlink with an Anchor+ClickListener.
I'd also use a FlowPanel+InlineLabels but it's up to you, the
HTMLPanel should work like a charm too:
FlowPanel container = new FlowPanel();
container.add(new InlineLabel("some text ");
Anchor link = new Anchor("link", "#token");
link.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
History.newItem("token");
DOM.eventGetCurrentEvent().preventDefault();
}
});
container.add(link);
container.add(new InlineLabel(" some more text");
...and/or you could "vote for" (i.e. "star") the issue 2901:

Re: Label + Hyperlink + Label
If it weren't such pita, it'd be sweet. But yeah, that worked great.
Since I'm doing this on a number of links in a bunch of text, I
wrapped up the click listener as such instead of new'ing one each
time.
ClickListener linkClickListener = new ClickListener() {
public void onClick(Widget sender) {
History.newItem(((Anchor)sender).getHref().substring(1));
DOM.eventGetCurrentEvent().preventDefault();
}
};
Thanks much.

Re: how to proxy all the methods in my RemoteServiceServlet
If go for non-spring solution, yes, you should override the
processCall().
Just take a look at the source, you should invoke the
RPC.encodeResponseForFailure(method, ex)
to encode the Exception and send back to client.
I didnt test. It may not compile, you may try anyway ... :)
public String processCall(String payload) throws
SerializationException {
try {
RPCRequest rpcRequest = RPC.decodeRequest(payload,
this.getClass(), this);
if (isValidSession()) // may add other conditions when should
check, when should not check..
{
return RPC.invokeAndEncodeResponse(this,
rpcRequest.getMethod(),
rpcRequest.getParameters(),
rpcRequest.getSerializationPolicy());
}
else
{
return RPC.encodeResponseForFailure(rpcRequest.getMethod(),
new NotLoggedInException());
}
} catch (IncompatibleRemoteServiceException ex) {
getServletContext().log(
"An IncompatibleRemoteServiceException was thrown while
processing this call.",
ex);
return RPC.encodeResponseForFailure(null, ex);
}
}
private boolean isValidSession()
{
//...
}

Re: how to proxy all the methods in my RemoteServiceServlet
Dean, GWT RPC clearly does not have the security aspect designed in; it seems designed for use with an orthogonal security mechanism, such as found in the HTTP specs. A bit of a leap, but have you mentally walked through what would happen if you ditched SESSION-based security and went with Digest? I think this approach would sidestep a huge amount of custom programming for you. Question is, what would you be losing that you can't live without? In my application, if I start up a browser and type the URL of my RPC service (before authenticating), the JAAS system in JBoss issues a challenge from way down in the stack (my RPC code never sees it), and the browser puts up a login form. This is pretty much what should happen when your logged in user encounters a session timeout.

Re: Label + Hyperlink + Label
... and incidently, the horizontalpanel approach never did work well.
Before I could figure out the problem, I just did the flowpanel+anchor
+clicklistener approach. Who woulda thought inline links would be
such a pain.
I star'd that issue...

Re: Label + Hyperlink + Label
Why faff about with an anchor and clicklistener when you can just put this
.gwt-Hyperlink
{
display : inline;
}
in your css?
You can then throw one lot of text at the HTMLPanel with
placeholders.

Re: Severe performance problem after upgrading to GWT 1.5.2 (final)
We noticed a slow down by just switching from 1.5RC2 to 1.5.2 more specifically on FireFox 3. I recently tested on Chrome and Safari 3 and the performance there is significantly better it seems to be well over 10x faster. I think there might be a bug using the scripting engine on FireFox and also IE. Or it could be the java scripting engine on Safari is really that much better. The overall app is much faster on Safari, but i would say the biggest issue is with RPC calls.

IE 6 doesn't finish load page
Hi people, I have a serious problem I suggest to use the gwt technology for the new projects of my company I use gwt 1.5.2 and gwt-ext 2.0.5 every thing go fine but when I try to prove the app in IE 6 the page load don't finish, my CPU get more than 50% for iexplorer.exe and don´t finish never. This usually happens the first time, then I kill process I try again and wrko fine woth out error of js, but unexpectedly it happens again and kill process and work fine ... and another time crash. I navigate for many topics, forums, suggest but I can't fine the exactly same problem, and suspect that is not for RPC calls because the data some time appear but the loading doesn´t finish never.

Collation and java.text.* support in GWT
Hi fellows, Does anybody know anything about support for Collation in I18N? Is it a planned feature? I've just realized, that sorting and comparing strings with respect to Locale is a really hard task in GWT, this feature is not supported in emulation library.

Re: colorating a tab
Does anybody know if it's possible to specify one or more CSS file(s)
(not styles, but rather files containing styles) from client code?
(currently I link them within HTML file).

Re: GWT-Gadget same-origin security restriction
Hello Jose,
The solution to send data with the request builder is to use a POST:
RequestBuilder rb = new RequestBuilder(RequestBuilder.POST, url);
The difference of POST and GET ist:
GET: only the "address line" is sent to the server. If you want to
send data with a GET you must put it as a parameter into the URL:
http://www.xyz.de&data=thisisthedatata
POST: you can provide an URL and send additional data:
requestBuilder.sendRequest(data, new RequestCallback() {
...
}
OK, I have got a question, too:
What is this line doing? url = intrinsics.getCachedUrl(url, 1);
What does it do with the URL and why can it avoid the same origin
problem?
I'm not using gadgets but I'm looking for a possibility how to call a
web service from GWT that is not on the same server as my GWT site.
(E.g. calling the amazon web service from my site (client) which is
built with GWT).
One solution of course is that I make a call to my server and the
servlet then calls the webservice and answers to the GWT client with
the response data from the web service. But I explicitly wnat to avoid
to make a call to my server.
If you have any idea please let me know.
Regards
Andreas

SocketTimeOutException
I am developing a GWT-based client that accesses a database frequently to display status information about an application. After receiving the response of the RPC-request, the client displays the status information fetched, checks if the application has ended; if not, the client will send another request... and the whole game repeats. Technology used: - Tomcat 1.6.0.14 - Java 5 - GWT 1.5.2, RPC After a while - the elapsed time is not always the same - I get the following exception: 29.09.2008 14:54:26 org.apache.catalina.core.ApplicationContext log SEVERE: Exception while dispatching incoming RPC call java.net.SocketTimeoutException: Read timed out at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:129) at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java: 716) at org.apache.coyote.http11.InternalInputBuffer $InputStreamInputBuffer.doRead(InternalInputBuffer.java:746) at org.apache.coyote.http11.filters.IdentityInputFilter.doRead(IdentityInputFilter.java: 116) at org.apache.coyote.http11.InternalInputBuffer.doRead(InternalInputBuffer.java: 675) at org.apache.coyote.Request.doRead(Request.java:428) at org.apache.catalina.connector.InputBuffer.realReadBytes(InputBuffer.java: 297) at org.apache.tomcat.util.buf.ByteChunk.substract(ByteChunk.java: 405) at org.apache.catalina.connector.InputBuffer.read(InputBuffer.java: 312) at org.apache.catalina.connector.CoyoteInputStream.read(CoyoteInputStream.java: 193) at com.google.gwt.user.server.rpc.RPCServletUtils.readContentAsUtf8(RPCServletUtils.java: 146) at com.google.gwt.user.server.rpc.RemoteServiceServlet.readContent(RemoteServiceServlet.java: 335) at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java: 77) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java: 290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java: 206) at jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:118) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java: 235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java: 206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java: 233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java: 175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java: 128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java: 102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java: 109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java: 263) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java: 844) at org.apache.coyote.http11.Http11Protocol $Http11ConnectionHandler.process(Http11Protocol.java:584) at org.apache.tomcat.util.net.JIoEndpoint $Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:595) I have to add that this exception never occured in hosted mode.

It redirects to a proxy running on the same machine where the cached gadget
was retreived from. Print out the value of 'url' after you retrieve it. It
should show a url to a different IP address, with the "real" url you want to
go to as a URL command line parameter.

Unfortunately, this proxy is gadgets specific. You could setup such a
proxy on your web site, however.

Re: Project bin directory
>From what I can see, the bin directory gets created when you initially import your project into Eclipse. Once created, -compile updates the class files in this directory. I just tried deleting it's contents ($ rm bin/*). No amount of running -compile would recreate the contents. I had to close and delete the project (without deleting the files) and reimport it for it to work. Is this right? What have others discovered?

erroneous "call failed on server" when servlet is successful
I have two GWT projects, call them ProjectA and ProjectB, that I would like to keep separate. When ProjectA.war file is created, I'm integrating ProjectB as a subproject. Eventually, there may be multiple subprojects inside ProjectA, and ProjectB may also be used as a subproject elsewhere. In my integrated projects, anchors in ProjectA can now call "./ ProjectB.html?foo=bar" without creating a new HttpSession, which is grand because ProjectA already holds a login and license on a remote application and database, and can share this seemlessly with ProjectB. That part works fine. On load, a servlet call starts in ProjectB to attach to the database and pull up a file. It all works just like when ProjectB runs standalone, EXCEPT I always get an alert with the message "The call failed on the server; see server log for details". Tomcat's localhost.log shows "java.lang.IndexOutOfBoundsException: Index: 0, Size: 0". (The full trace is at the end of this message.) This exact same message occurs again when ProjectB makes a servlet call, although otherwise the call is behaves correctly. My distrib directory for ProjectA looks like a normal GWT distribution directory. I then insert ProjectB (using Robert Hanson's "GWT in Action" Ch 16 as a guide). I get this: ProjectA --distrib --**.cache.html, etc --ProjectA.html --ProjectA.css --ProjectB.html --ProjectB.css --ProjectB --**.cache.html, etc --WEB-INF --classes --lib --web.xml I have merged the web.xml files of both projects as well as the classes and lib directories. In web.xml, servlets from ProjectA look like aServices /servlet/aServices While ProjectB looks like bServices /ProjectB/servlet/bServices Any ideas what's happening? You can see from the message below that the error seems to be coming from GWT.

Re: Running Windows-built GWTTestCase on Sparc/Solaris ??
The error looks like the GWT tests are trying to use the Windows development kit on your Linux machine. To run tests on your Linux build machine, you need to switch your build to use the GWT Linux distribution. What's happening is that the GWTTestCase tests are trying to start up a headless hosted mode browser, which is different on each platform (Mac, Windows, Linux). Use the Windows dev kit on your laptop and the Linux dev kit on your build machine. To make this, you'll need to do some per-OS switching in your build scripts -- in Ant, you may need to use the with a conditional tag to set the appropriate libraries. See this thread for more information: http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/ecebc719ec7d2a10 Dan > Can't load library: .../libswt-win32-3235.so > java.lang.UnsatisfiedLinkError: Can't load library: .../libswt- > win32-3235.so > at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1650) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
