content assist -> UnknownHostException [message #473709]

Hi!

I use eclipse with wtp + jsf behind a firewall.
If I try to use the content assist in EL parts to get some beans or
their properties, I get an UnknownHostException: java.sun.com.
Content assist on taglibs is working fine.

What's wrong here?

Are you also behind an http proxy? If so, you will need to go to
Windows->Preferences->Internet->Proxy Settings and configure your proxy.
This is a known issue where the logic that processes the faces-config file
to load bean information tries to cache the DTD for the config file. If
it fails to connect it can cause these sorts of problems.

You can monitor https://bugs.eclipse.org/bugs/show_bug.cgi?id=154439 to
track this issue.

java.sun.com ist not in the list of allowed web sites.
Is there something else I can do?
Nevertheless the JSF plugin trys to load a DTD from java.sun.com and
freezes my eclipse.
Can I install this DTD local or on a server in our intranet to prevend
the plugin from looking to an adress outside of our network?

Hi Tino,

I'm trying to get an answer for you on that. One thing you could try as a
workaround is to hack the WTP internet cache. The files are in in your
workspace directory under
metadata/.plugins/org.eclipse.wst.internet.cache. I get an entry in the
cache.xml file that looks like this:

<entry expirationTime="1162506301968" lastModified="1080458708000"
location="302164523.cache"
uri="http://java.sun.com/dtd/web-facesconfig_1_1.dtd"/>

The location attribute points to a file of that name in the same directory.

Hi Cameron,

this doesn't help much. Everytime when I press CTRL+SPACE I get this
error again. :-(
It seems that the wtp internet cache is not used.

We have received a patch from Matthias Fuessel at GMX that appears to at
least partially address the problem. Stay tuned in the New Year when we
will apply this. You can monitor
https://bugs.eclipse.org/bugs/show_bug.cgi?id=154439 for updates.
