Scriptdispatch.oxt

with lo3.5 it is not possible to install script dispatch java extension.

steps to reproduce:

- try to install attached *.oxt from command line:

  unopkg add ScriptDispatch.oxt --shared --verbose

  [...]
  ERROR: Fehler beim Aktivieren von: ScriptDispatch
   Cause: (com.sun.star.lang.IllegalArgumentException) { {
   Message = "Failed to register package
   for vnd.sun.star.expand:$UNO_SHARED_PACKAGES_CACHE/
   uno_packages/lu145p4x.tmp_/ScriptDispatch.oxt/
   ScriptDispatch/", Context = (com.sun.star.uno.XInterface) @0 },
   ArgumentPosition = (short) 2 }
unopkg failed.
?????????????????????

with lo 3.4.5 same *.oxt can be installed without any problems.
to verify, open attached "StartScriptDispatch.odt" and press button.

Confirm. Also, preinstalled Java macroses (/opt/libreoffice3.5/share/Scripts/java) do not appear in the "Run Macro..." dialog (menu Tools/Macros/Run Macro...)

[Oliver-brinzing (oliver-brinzing)]

why is this bug not fixed in lo3.5.1?

[Pmladek-y (pmladek-y)]

I wonder if it is related to removing of the 3-layer structure.

It affects an extensions that is not installed by default => It most likely affects only limited group of users => It can't block the release => lowering the severity a bit.

[Sbergman (sbergman)]

Rather a regression introduced with gbuild'ification; ScriptProviderForJava.jar no longer contains a RegistrationClassName in its META-INF/MANIFEST.MF.

[Pmladek-y (pmladek-y)]

Also I do not see /opt/libreoffice3.5/share/extensions/script-provider-for-javascript. I am not sure if it is not longer needed.

using "ScriptProviderForJava.jar" from lo3.4.5 works for me

The script providers for Java (BeanShell) and JavaScript are not implemented as .oxt extensions (unlike the script provider for Python), so do not end up in share/extensions/.

So will it be fixed for 3.5.2 ? Added to most annoying 3.5 bugs ?

[Oliver-brinzing (oliver-brinzing)]

bugfix should be quite simple:

take "MANIFEST.MF" from lo3.4.6 and copy
into META-INF/MANIFEST.MF from lo 3.5.1's
"ScriptProviderForJava.jar"

However, this is not enough to make Java scripts actually work. (However, it apparently suffices to make this issue's original problem of a failing unopkg add go away -- even if subsequent testing of StartScriptDispatch.odt fails.)

fdo#46102: Fix Java script examples after gbuild'ification

[Sbergman (sbergman)]

@brinzing: With the above three commits, Java scripts in general work again (and esp. the preinstalled examples mentioned in comment 2).

However, your attached ScriptDispatch.oxt/StartScriptDispatch.odt still do not work for, but do not work for me in LO 3.4.5, either. In both versions I get an
error message "Cannot resolve script location for script = org.test.java.ScriptDispatch.execute."

I'm intending these fixes for inclusion in LO 3.5.x, potentially even still LO 3.5.2, see <http://lists.freedesktop.org/archives/libreoffice/2012-March/028759.html> "[REVIEW-3-5][REVIEW-3-5-2?] fdo#46102 script dispatch java extensions are broken."

[Oliver-brinzing (oliver-brinzing)]

you have to install the "ScriptDispatch.oxt" with "--shared" option, for example:

 unopkg add ScriptDispatch.oxt --shared --verbose

cause the command button url contains the location "share":

vnd.sun.star.script:ScriptDispatch.org.test.java.ScriptDispatch.execute?language=Java&location=share:uno_packages/ScriptDispatch.oxt"

[Sbergman (sbergman)]

OK, then it indeed works on my LO master.

Looks like <http://cgit.freedesktop.org/libreoffice/core/commit/?id=dd6c4f4db1d62268d73e09ae52d23f760a967dcc> "fdo#46102: Load Java scripts with class loaders that actually find them" was not necessary after all and rather caused new regressions, see bug 49517.
