File Upload and Download in RWT standalone [message #119963] |

I'm having difficulty implementing File up and download in a RWT
standalone app. Most of the existing threads on this topic uses plugin and
therefore plugin.xml. The only helpful thread I can find is the one I
pasted below, where Rüdiger responds to someone else that had the same
exact issue as me currently while trying to use the download widget:
Could not evaluate javascript response:
Object expected
So I tried following Rüdiger's suggestion as best I could, and I think I
have the upload servlet up. Here's the piece of web.xml I added:
<servlet>
<servlet-name>FileUploadServlet</servlet-name>
<servlet-class>org.eclipse.rwt.widgets.upload.servlet.FileUploadServlet </servlet-class>
<load-on-startup>0</load-on-startup>
<init-param>
<param-name>org.eclipse.rwt.resources</param-name>
<param-value>
org.eclipse.rwt.widgets.internal.resource.UploadButtonResour ce,
org.eclipse.rwt.widgets.internal.resource.UploadResource,
org.eclipse.rwt.widgets.internal.resource.UploadFieldResourc e,
org.eclipse.rwt.widgets.internal.resource.UploadFormResource
</param-value>
</init-param>
<init-param>
<param-name>httpcontextId</param-name>
<param-value>org.eclipse.rap.httpcontext</param-value>
</init-param>
</servlet>
But I'm guessing I'm not setting the httpcontextId correctly, or something
else is wrong. I can see the servlet is deployed when I go to JMX console
and when I try to go to /upload I get:
<?xml version="1.0" encoding="utf-8" ?>
<response />
If anyone can give me some pointers, I would be eternally grateful. :D
Any instructions or example code for setting up upload and download server
would be much much appreciated as well!
Cheers,
Howard
====================== previous thread pasted ==========================
the error occurs because the Javascript files for the upload widget are
missing.
Usually they are registered via the extension point
'org.eclipse.rap.ui.resources'. An IResource implementation must be given
there that describes the resource. RAP puts all Javascript resources
together and delivers them in the index.html to the client.
In your case this information is never evaluated.
But there is more. All what is currently specified in the plugin.xml of
org.eclipse.rwt.widgets.upload needs to be specified otherwise.
Here is what you would need to do when using RWT standalone (without
having actually tried it)
* specify web.xml
<init-param>
<param-name>org.eclipse.rwt.resources</param-name>
<param-value>
[comma-separated list of IResource implementations]
</param-value>
</init-param>
Take the class names from the plugin.xml of
org.eclipse.rwt.widgets.upload
* register the /upload servlet (also see plugin.xml)
* the org.eclipse.rap.ui.themeableWidgets extension needs a
replacement too, but right now, I can't find where to specify
this in the web.xml. With some luck, the upload widget may
work without theming.

Hi Howard,
it's difficult for me to reproduce this problem because I don't have the
setup of running a RAP app without Equinox. Maybe, you can post a small
example WAR file that you use?
Registering the FileUploadServlet in your web.xml is no longer necessary
because it isn't used any longer (marked as deprecated). Instead the
class FileUploadServiceHandler is used. This ServiceHandler is
registered automatically when the Upload-Widget is used. However, this
should not be the reason of your problem...
Regards,
Stefan.

Thanks for the reply Stefan. At least I know I don't have to worry about
setting up the servlet correctly, that's helpful info!
What about theme/branding? Does Upload Widget still require themeing? If
so, any idea on how to do theme in css with RWT standalone?
I've attached a simple war file as requested. A couple of notes:
I'm using HEAD in Upload Widget, and RAP 1.2 M4, deployed in JBoss. To
access the servlet: deploy in web server, url is
https://localhost:8080/rap/main
Instead of including my actual code, which I'm not allowed to share, I
simply changed the upload demo code to create a new Display instead. The end
result is a similar, although slightly different, error. See below.
I didn't find a jar for the upload widget, so I just manually zipped it up
and called it upload.jar. This seems to work fine.
I largely followed the example given in the FAQ to setup my RWT standalone
app, and so far it's working quite well.
The war is too large to attach, so I've stripped out the library jars. It
needs:
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
org.eclipse.core.commands_3.5.0.I20081202-0800.jar
org.eclipse.equinox.common_3.5.0.v20081201-1815.jar
org.eclipse.rap.jface_1.2.0.20081223-1131.jar
org.eclipse.rap.rwt.q07_1.2.0.20081223-1131.jar
org.eclipse.rap.rwt_1.2.0.20081223-1131.jar
Those are the jars I normally include.
I'm starting to hit a wall...not sure what else I can do. My only hope is
someone in the newsgroup will be kind enough to help!
Cheers,
Howard

Howard,
the following is justa guess, I haven't tried it myself. The
Javascript error *may* be caused by the fact that the upload widget
is not known as a themeable widget.
When running the Workbench, themeable widgets are registered via the
org.eclipse.rap.ui.themeableWidgets extension point. A similar
mechanism is currently missing for RWT standalone.
You could try the following to work around this:
1. register a new ServletContextListner in your web.xml
*before* any other context listener
2. in this context-listeners' contextInitialized() method
call ThemeManager.getInstance().addThemeableWidget()
and pass in the upload-widget-class

Re: File Upload and Download in RWT standalone [message #120991 is a reply to message #120972] |

Hi,

Right, but the content of this file is delivered only if the RWT theming
knows about the themeable widget. As the themeableWidgets extension does
not work in standalone mode, the appearance will be missing. This should
result in a Javascript error or warning at some point (apart from a
different look of the embedded text field), but this is obviously not a
problem in your case.
Regards, Ralf
