Re: Gwt RequestBuilder + Servlet issue

2011-09-03 Thread suresh babu
use Window.open(/pdfUrl,  _blank, );  in gwt to call the servlet, in
servlet write the code for generating pdf.

 So you want to send some data to the servlet and want to display a PDF
 (which is generated by the servlet based on the data sent) in the browser?

 There are two ways of how to do it:

 1.) Using RequestBuilder you could generate a AJAX call to your Servlet (as
 you did it). However in the callback method of the RequestBuilder you will
 get the response from the servlet (probably the PDF binary data) and then
 you could use that to open a new window with the binary PDF data.

 however I think the easier approach is the following:

 2.) Have either a form or a URL which points to the URL of the servlet
 responsible for generating the PDF. The data you want to pass to the servlet
 can bei either passed by POST (form) or GET (url) and in the servlet make
 sure that response headers are set properly (application/PDF).

 second appraoch is easier.

Re: HTML5 Offline Web-Application

2011-09-03 Thread -sowdri-
Hi, 

The above solution was working fine, i even deployed a version and tested it 
live!

But suddenly i've started getting this error: 

DevMode warning: Clobbering appcache.nocache.manifest to allow debugging. 
Recompile before deploying your app!

And the appcache.nocache.manifest_*user-agent *doesn't contain the js file 
name! 

Any idea what is causing this???

Re: DevMode warning: Clobbering appcache.nocache.manifest to allow debugging. Recompile before deploying your app!

2011-09-03 Thread Thomas Broyer
I guess the linker detects the DevMode and adds an entry for hosted.html in 
the manifest; and because DevMode does not compile the permutations, the 
manifest is missing the *.cache.html.
Running GWT Compiler would fix this.
This is actually not much different from the DevMode generating a dummy 
*.nocache.js; except that I guess the linker always replaces the manifest, 
contrary to DevMode (which only generates the dummy file when it doesn't 
already exist –or it's timestamp is older than the one of the GWT SDK, which 
would mean it's from a different GWT version–)

…only guessing though; didn't look at the code.

Undeployed GWT

2011-09-03 Thread pete
Hello,

since I sometimes just play around with client side GWT, creating some
pure javascript to display sth. in the browser, I wondered, if it is
possible to comile/arrange the project in a way that I don't need a
server? Obviously normally just clicking the html file doesn't work,
instead I get

Unsafe JavaScript attempt to access frame with URL file:///path/blabla.html
from frame with URL 
file:///path/blabla/war/blabla/3C6B7EC5C425BB1E705BE5E8FE20CE6D.cache.html.
Domains, protocols and ports must match

Can anyone provide help on how to run the javascript without needing
any server? (meaning really no server, not just no server calls, I
don't want to deploy the project at all, just run it inside a local
html page)

Greetz,
Peter

Re: GWT 2.3 XSRF Invalid RPC token (Session cookie is not set or empty! Unable to generate XSRF cookie)

2011-09-03 Thread Ali Jalal
Hi,

I see this error sometimes (not always), so for solving this problem, I
first send a Rpc and fixing JSESSIOID cookie on server-side by setting it to
getThreadLocalRequest().getRequestedSessionId(). So I'm sure that JSESSIONID
cookie exists. Then calling XSRF to generate XSRF token and it works.

Note that JSESSIONID should not be changed (Session on server-side should
not be invalidated). If JSESSIONID being changed (by calling
httpSession.invalidate() method) you should generate new XSRF token and set
it to all XSRF-protected service async objects.

SimpleRequestProcessor call findDomain twice

2011-09-03 Thread Andy
Hi,

I have an example class

public class Employee {

public static Employee findEmployee(ObjectId id) {
.
System.out.println(find);
return employee;
}
..
}

When triggering the findEmloyee from the client side via
RequestContext, the line 'System.out.println(find);' was called
twice, I check that it is called from the class
SimpleRequestProcessor, from the two method

method createReturnOperations, triggered by the line
 } else if (!service.isLive(domainObject)) {
in the method

method processInvocationMessages, triggered by the line
domainReturnValue = service.invoke(domainMethod,
args.toArray());

Both this method is triggered from the method
void process(RequestMessage req, ResponseMessage resp)

The questions is why createReturnOpration need to find the employee
again which i think is unnecessary.

It is just loaded from the database and then it will hit the database
again for the same query? Am I doing something wrong here ?

Kind Regards
Andy

Re: SimpleRequestProcessor call findDomain twice

As the code says: it tries to determine whether the object still isLive 
(in order to tell the client that it has been deleted, or possibly updated).

If you have a better algorithm to determine liveness, use a Locator and 
override its isLive method.

JAXB + GWT

2011-09-03 Thread Kyle Anderson
I have an XML Schema defined in XSD format.  Basically, there are a
whole lot of objects with attributes associated with them.  The
attributes have various types (strings, enumerated types, integers).
The restrictions on these attributes are all defined in the XSD
format.   I would like to create an editor in GWT which allows the
user to edit a file in XSD format.  The editor should be able to
create a form using the XSD.  For example, if there is an enumerated
type attribute, the editor should create a drop down menu.

I experimented with JAXB to generate the java bean classes from the
XSD format.  The problem with this is that you cannot do reflection in
GWT, so there's no great way to view the attributes of the class in
order to create the editor window.

I imagine people have done similar things before.

Thanks!!
Kyle

you need to use JAXB on the server side, not on the client side. There you
can use reflection. Parse your XML and set to POJOs and get back to client.

nocache JavaScript file in the HTML file, hence the blank page. For
some reason the GWT plugin will not create a GWT HTML file after
clicking on the Finish button in the wizard. Problem exists for both
Google Web and Dynamic Web projects. Can only get a GWT HTML file by
grabbing one from a Google Web project (just an ordinary Java project)
that is created with samples.

Good way to strip a string of tags?

2011-09-03 Thread darkflame
Sorry if this is already covereddidnt have much luck searching.

I need a way to return a simple plane text version of a string that
may or may not contain other formatting.
Ideally this would cover formatting from a RichTextBox, HTML tags or
something pasted in from Word.
Basically anything not normal text I want removed.

After googleing I got suggestions of various Regexs, but also warnings
that it isnt a very good way to do it and you need a full HTML parser.
So I'm now wondering whats the best way to do it in GWT.

Thanks,
