Re: css background image
Agree with Jens. You can also check the style in dev tools. If it's not being found, it's a problem with the path to the image. --- phone.brevity.typos.cheers On 6 Apr 2014 09:43, Jens jens.nehlme...@gmail.com wrote: Check your browsers dev tools to see if the image / css file gets loaded by the browser or if an HTTP 404 NOT FOUND occurs (see network tab in dev tools).

offsetheight not changing in button when fontsize is changed
Hi there, I am creating a button (b) and changing its font size. The offset width changes automatically, but the height is always the default. b.getOffsetWidth() changes accordingly to the font size, but b.getOffsetHeight() is always 26 (the initial size of the button). Anyone seen something similar? I am using GWT 2.5.1, but have tried with 2.6.0 with the same result. Am I using the offsets incorrectly? Many thanks for any info! -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: css background image
You can try using quotes around the name of the image, and using a relative
path. something like:
background-image: url(img/wood.jpg);
note that there is no / before img (a relative instead of an absolute path
to the image). Would that work?

Hello everyone) I've recently faced a problem. I don't know how to set the

What I did:
1) I've created a folder named img in the war folder of my gwt project
2) Then I've coppied there a.jpg image called wood.jpg.
3) Then in my css file I've got the following written:
body{
background-image: url(/img/wood.jpg) repeat;

4) Surely I've added a link to that css file in my HTML Welcome page
When I run this project the background is white. My java code has nothing
that affects the backround.
So, would you please help me to handle this problem?

GMaps controls not getting ClickEvents
I am no longer getting ClickEvents on google maps controls I add to
map
I have a simple GoogleMaps control, just an image in html:
HTML infoWidget = new HTML(div id='tip-of-the-day-control'img
src='/oeg/images/info_32.png' title='Helpful Tips'//div);
Which I place on the map using Mapitz (yes I know, but I have a
working version thats updated if anyone is interested), this code
literally just puts the html element on the map as a control.
GControlPosition infoPosition =
new GControlPosition(GControlAnchor.G_ANCHOR_TOP_RIGHT(), new
GSize(7, 30));
getGmap().addControl(new GControl(infoWidget, infoPosition));
to get ClickEvents I used to do this...
infoWidget.addClickListener(new ClickListener() {
public void onClick(Widget sender)
{
doTipOfTheDay();
}
});
which I changed to this in the 1.6.0 world,
infoWidget.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent ce)
{
doTipOfTheDay();
}
});
neither of which work in GWT-1.6.0/1.7.0 - anyone else run into event
issues w/ controls?
With other Gmaps objects I have no problems w/. I'm getting mouse
clicks on the map, on markers etc,
but controls, not so much

Re: Search Engine Indexing
Quick answer for me - no, never expected it to be indexed so there was never any wondering The trade off that Eric mentions was always made pretty clear by the search engines and in my case, we decided to render pages we wanted indexed outside of GWT and we have a parallel application structure to render these pages with a minimum of javascript. We still have some problems: 1. a slide show of multiple pictures is not so easy to deal with 2. we use a couple of 3rd party embedded components, that we like, but we'll have to replace at some point because the content in them doesn't get indexed I think your second question makes a presumption that a GWT rendered webpage has only a single URL. This is not necessarily the case. There are some GWT apps out there that have large URL spaces based on content that they render. They have an indexing problem if they cannot provide the same content sans GWT execution.

Re: Search Engine Indexing
Hi Bryan I recently had the chance to speak with some good SEO types and the subject of javascript did come up. The bottom line is don't hold your breath waiting for this to happen in any search engine. I think its easy to appreciate how difficult it would be for a search engine to do this. You'd essentially be creating a virtual browser machine which would be loading a page and executing it (as you point out) but it's not so simple, how much execution should be done? How to does the engine know when to stop? It's kind of a halting problem. The other thing we have to keep in mind is that the cost of this is pretty high and there are a *lot* of pages out there to index. I feel your pain, I'd like to create a commenting system using GWT, but any of the content in that commenting system is going to have to be sent down to the client in HTML if I want it indexed. I was discussing another similar problem I have where we use a component that is wrapped by an iframe, how much of the content in that iframe is going to get parsed? Not clear. jos On Jan 23, 11:59 pm, bryanb webbt...@gmail.com wrote: That's the point of my query/question, Why can't the Google bot understand Javascript ?

Re: RPC call returning ListString fails

the gwt-sl.jar version I was using (fairly old as previously stated) I
downloaded the 0.1.5b (latest version still using Hibernate4GWT) and
put everything back to ListString and it worked inside and outside
of eclipse. Given this was the only thing I changed, possibly a
problem in the old library.

fine.
Does anyone know, is it not OK to use ListString as a return
specifier?

Re: J2EE and debug in hosted mode
Bandesz, Gregor is pointing you in the right direction w/ option #1, and the link he gives is enough to eventually get you there, but there is one thing you have to do in your GWT code or it will never work. Your RPC servlets all have a setServiceEntryPoint() call that is made to tell them where they hookup. By default in hosted mode the GWT runtime will tell your GWT application that the app server is on localhost so you need to override that by changing the following code which should be in your onModuleLoad() method. The code example below is in my deployment setup, when I'm debugging the application I comment in the first two lines and comment out the 3rd line. Note in the second statement I'm telling GWT where the the service entry point really lives. The third statement would point it back to the localhost because that's where hosted mode lives. There is a second important step that I'll mention here. After compiling your GWT code, it does need to be deployed to your testing server so that the hosted mode browser takes the code from that server. Once you switch to -noserver the local tomcat goes away and there's nothing serving up your application. When you run the hosted mode debugger, you just need to type in the address of your application on the address bar like you would if you were really deployed, your application will be served by your test server and load up into the hosted mode debug browser. Try the GWT documentation link and these two points, and it should work. Admittedly it is a painful process the first time you try to get it to work, but it does work. /** ECLIPSE CODE - comment in the next 2 lines and comment out the line directly * after these three to run with backend server in eclipse System.out.println(GWT module base URL - + GWT.getModuleBaseURL()); geoServiceTarget.setServiceEntryPoint(http:// staging.abaqus.net/geo/gcb/geoservice); */ geoServiceTarget.setServiceEntryPoint(GWT.getModuleBaseURL() + geoservice); On Dec 7, 7:34 pm, gregor greg.power...@googlemail.com wrote: couple of approaches 1) Simply use -noserver option. You need a build script to deploy your RPC servlets and your EJB layer to Glassfish on demand and activate remote debugging to make this work effectively, but lots of people do it this way. See http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=goog... 2) You can run your RPC servlets in hosted mode Tomcat instance leaving your session beans on Glassfish with a bit more work. You need to use trad JNDI to try for a local reference to your session beans, and if that fails go for the remote reference instead. I don't think the new annotation stuff works for this.That way you get a local ref in production and a remote one in dev from the same code. If you use the ServiceLocator pattern it makes this easier. On Dec 7, 2:26 pm, Bandesz band...@blog.hu wrote: I'm developing a J2EE application with GWT using NetBeans 6.5, Glassfish v2.

Re: -noserver 1.5 RPC Help
Hi Christopher I had a tough time getting this to work at first too (using 1.5). One of the changes I made that I have not seen mentioned in this thread is that I had to change the service entry point to something different than what Bruce had in his initial post I had to use a full URL to my server, see example of my service entry point below. Also a couple of other things - you need to copy the compiled GWT application directory to the server directories (and recopy if you change the interface) and don't forget that you need to alter the address in the hosted mode browser to the actual page on your server or the application won't load. from bruce johnson's post 5) Make sure that your client-side code references the right service entrypoint using ServiceDefTarget. In this case, it would be something like serviceDefTarget.setServiceEntryPoint(/myproject/myservice). example of what I put in my code geoServiceTarget.setServiceEntryPoint(http://staging.abaqus.net/geo/ gcb/geoservice); hope this helps jos On Oct 14, 9:34 am, Christopher Venning [EMAIL PROTECTED] wrote: I cannot seem to get the -noserver mode working with RPCs. I got it to work in 1.4 but have changed environments in the last year. There don't appear to be any Group postings about getting it going since 1.5 was released. Bruce Johnson's original posting (http:// groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/ 338c4b765d7dfc39) doesn't appear to be the 1.5-supported method, based on the current Developer's Guide (yes, I tried it anyways and failed). Working off ofhttp://code.google.com/docreader/#p=google-web-toolkit-doc-1-5t=FAQ_..., Hosted Mode hooks in appropriately (changing Java code and refreshing the Hosted Browser changes content). However, the RPCs fail. I am probably doing something dumb, and would appreciate someone pointing that out.
