Description
Hello,
I'm having a problem with one of the WMS sources I added -- and which was recently added to WMSplugin, i.e. "Sicily - Italy". While trying to understand what is happening, I tried, and it also happens with the Yahoo! imagery. Loading one of these WMS causes no tiles appearing in JOSM, and "image == null!" appearing in console.
Could this be related to network latency?
I tried with other WMS sources (i.e. Lodi - Italy), and they load just fine. Also, the failing WMS's work on other mappers' computer/networks.
If this is caused by network latency, could you please print a more explanatory message? And eventually increase the timeout :)
Thank you!
David

Even adding high timeout values, doesn't work. I suspect the culprit is the first Exception raised -- the messages "image == null!" appear immediately, without waiting for any timeout to happen.

Reading the Java API, I saw that it's possible to directly pass an URL to Image.IO.read(). I tried this too, but it still fails.
Any info on how I should debug this? I'm willing to provide more information, just I don't know how to do it.
Next thing I'm trying to do is reading the Java source, to see where Image.IO.read() could fail. However, for the tests with wmsplugin, I needed to recompile it each time. Please don't let me recompile Java N times. :)
Setting priority to critical: the wmsplugin is not at all usable with this bug.

And, it turns out that it works with Sun's Java. I'm using OpenJDK, and installing Sun's indeed works.
However, it worked before with OpenJDK as well, so I'm going to report this to them with a minimal testcase.
Thanks for the.. "attention" *grin*

same here on debian testing:
/usr/lib/jvm/java-6-openjdk/jre/bin/java
fails with WMS and Yahoo and runs a lot slower!
/usr/lib/jvm/java-6-sun/jre/bin/java
works fine.

I never got WMSplugin work, whether under Linux nor under Windows; using proxy or not

If enter this URL in Firefox, it works fine; in JOSM the console says "im == null!"

Please don't mix this up. Yahoo-access and WMS Sicily are two different things, as they use totally different ways of acquiring the data. For Yahoo you need a download tool, WMS is accessed by plugin directly.
@WillyTM: Your installation of the download tool is probably wrong. How to do this right has been discussed often enough. Use Google to find help.
comment:11 by , 15 years ago
Download tool in all cases is webkit-image. It semms to be found, when the path is changed to an inexistend path the console of JOSM mentions this: java.lang.Exception: Could not start browser. Please check that the executable path is correct.
This is the output of the console running JOSM 2890 with WMSPlugin 19626:
Grabbing HTML http://josm.openstreetmap.de/wmsplugin/YahooDirect.html?bbox=12.42 13836,51.2971698,12.4606918,51.3364780&srs=EPSG:4326&width=500&height=500 im == null!

In this case the instalation was under Windows, josm-latest.jar, webkit-image, Qtxxx.dll, mingwm10.dll and imageformats folder in one directory, starting from console from this directory
All installations done according to http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WMSPlugin

I think I have the solution: WMSplugin/Webkit-image does not like connections over proxies, when I use JOSM without a proxy WMS works as expected
But it is nowhere written that WMSplugin cannot be used with proxies
so it is still a defect either in WMSplugin/Webkit-image or in the documentation

WMS plugin does not use JOSM proxy. It needs to use either system setup or proxy environment variables.
I just tried connecting to my router via ethernet rather than wifi, to try reducing latencies, but this still happends.
I just attached the log of this session; this time I could see an Exception, which might be a good point to start investigating the bug.
Thank you!
