If you want it sooner than WTP 3.5, or WTP 3.4.3 assuming there will be
one, then you could build a fixed version of the required plug-in.
While not trivial, it is pretty straightforward. If you want to pursue
this, you would begin by installing in your current Java EE SR2, or in a
temporary installation, the "WST Server Adapter Plug-in Develop
Resources" item, i.e.:
1. Execute Help -> Install New Software...
2. Select "The Eclipse Web Tools Platform (WTP) software repository"
3. Expand "Web Tools Platform SDK (WTP SDK) 3.4.2"
4. Select "WST Server Adapter Plug-in Develop Resources" and proceed
with finishing the installation.
Once you have this source installed it's straightforward to import a
project for the needed plugin, make the small change needed to fix the
issue, and build a drop-in replacement for the plug-in. I can provide
the details if you want to pursue this.
Cheers,
Larry

Would you mind to explain more details? I have the same issue and i want to solve it. Actually, i use the browser separately.
Somebody know if the new release will take much time?
Regards,
MV.

The WTP 3.5.0 release is due out near the end of June. I'm not aware
that any WTP 3.4.3 release is planned at this time. It is a fair number
of steps, but they are all straightforward, including the edit to fix
the bug. Once you have completed the four steps above, let me know and
I'll give you the remaining steps.
The general process will be to create plug-in project with the
appropriate source, make the edit to fix the bug, and then build the
plug-in. If done with the appropriate steps, you get a replacement
plug-in jar with the same version as the one it replaces. You switch
the jars, and you have the bug fix.
Cheers,
Larry

Sorry for the delay. Here are the steps:
Phase 1: Create a plug-in project for the plug-in you need to patch.
1. Create a new workspace (recommended) or open an existing one.
2. Select File -> Import...
3. Expand "Plug-in Development", select "Plug-ins and Fragments", then
click Next>.
4. In the "Import As" section, select "Projects with source folders",
then click Next>.
5. Enter (or copy & paste, no quotes)
"org.eclipse.wst.server.preview.adapter" into ID field at the top and
click "Add All->". This should move this one plug-in to the right pane.
6. Click Finish to import the "org.eclipse.wst.server.preview.adapter"
plug-in source into a project.
7. Expand the root of the project and ensure it contains a folder named
"src". You will only get the "src" folder if you have the "WST Server
Adapter Plug-in Developer Resources" installed.
Phase 2: Apply the changes needed to update the plug-in. Since there is
a bug with a patch attached that can be used to apply the changes, the
following steps will take advantage of that.
1. Open Bug 402848[1] in a browser.
2. Click on the "Patch v1.0 for 3.4.2p" attachment link to open the patch.
3. Starting with the second occurrence of a line starting with "---",
select this line through the end of the text and copy it to the
clipboard. This contains the changes to the
PreviewLaunchConfigurationDelegate.java file which is where the fix is
needed. You don't want the upper portion of the patch as that would
change the version of the plug-in, and that would complicate things.
4. Back in Eclipse, right-click on the
"org.eclipse.wst.server.preview.adapter" project and select Team and
"Apply Patch...".
5. Leave Clipboard selected and click Next>.
6. Ensure the "org.eclipse.wst.server.preview.adapter" project is
selected, and click Next>.
7. Set the "Ignore leading path name segments" to 3. The "Patch
Contents" window should change to have a blue left pointing arrow
instead of red x indicators.
8. Click Finish to apply the changes.
Phase 3: Create the replacement jar. Due to the approach in Phase 1, the
name of this jar will be identical to your current jar, which simplifies
updating the Eclipse installation.
1. Right-click on the "org.eclipse.wst.server.preview.adapter" project
in the Project Explorer or other navigator view and select Export...
2. Expand "Plug-in Development", select "Deployable plug-ins and
fragments", then click Next>
3. Click the Browse... button next to the Directory selection in the
Destination tab followed by OK. This will set the output directory to
be the same as your workspace.
4. Click Finish to build the replacement plug-in jar. It will appear in
a "plugins" folder under the root of your workspace.
Phase 4: Replace the installed plug-in jar with the fixed version.
1. Exit Eclipse if it is running.
2. Under the "plugins" folder of your Eclipse installation, move or
rename the
org.eclipse.wst.server.preview.adapter_1.1.101.v20121107_1651.jar if you
don't want to overwrite it with the patched version. If you have a
different version, it means you aren't using Juno SR2 and hopefully you
installed the "WST Server Adapter Plug-in Developer Resources" that
matched your version.
3. Copy the
org.eclipse.wst.server.preview.adapter_1.1.101.v20121107_1651.jar from
the "plugins" folder under your workspace and paste it to the "plugins"
folder of your Eclipse installation.
You should be able to run Eclipse now with the fixed plug-in. Because
the patched jar had the same version number, no additional changes are
needed. The steps above are pretty brief. If your environment diverges
from what these steps are expecting, let me know.
Cheers,
Larry
