RES: RES: Problem Trying call LibreOffice from Java

2013-05-14 Thread Fernando Digitaldoc
Good Afternoon Stephan,
We managed to solve the problem. We do not know if it is the most suitable
solution, but for now it worked.

Following, new sample project now a project with a Java Web and a JNLP
application.
https://dl.dropboxusercontent.com/u/30314039/JavaCallLibreOfficeWeb.rar

Well, I'll explain the workings ...
We are using a old applet and not the JNLP, made an adaptation, almost
simulating a JNLP.

The initial method of the applet calls the method downloadAndInject() ... 
- This makes the applet open a http connection to the server (through a
servlet) and make the download of the required DLLs and JARS for execution.
- They are written in a user directory and then we create a ClassLoader that
will knows that paths. 
- This classloader is injected into Java classloaders and this libs become
available, as they would be if there was a statement classPath.
(A solution is complicated, and not recommended, we want to leave, but .. it
works.)

Well, a next step is the Start method of the applet and it performs
basically two steps.
1 - Start OpenOffice - method initOpenOffice ()
Starts soffice from the command line with some parameters.

2 - Call a Text Editor - new WriterEditor (destFilePath)
It is just getting all the logic directly in the constructor ... 

Well, it creates a ooBean and a frame in StartUI() and then is called the
swriter in method loadDocument ()

To run the test simply turn the project into a web container such as Tomcat
and access the application ..
http://localhost:8080/JavaCallLibreOfficeWeb/

The main index is loaded with jnlp libre.nocache.jnlp that is in the
folder: WebContent / applets / .. This folder is also the jar applet
checkout.jar that is generated with ant buildApplet.xml that lives in
the ant folder.

Currently as I said, we can fix, or work around the problem.
Ubuntu occurred in an error saying that the library officebean could not
find or load the library libjawt.so that comes with java.
java.lang.UnsatisfiedLinkError:  /home/gha/myapp/lib/libofficebean.so:
libjawt.so: cannot open shared object file: No such file or directory

What we did was take this lib and put together the project.
Now besides the jars and we also do officebean.so and libjawt.so
download and load (with a injection gross)

Now i want some help in some points:

* JNLP - Now we want instead of the old applet, use the JNLP really, but we
can not load library (dll or .so), even if it is inside a jar that stated in
resources (currently commented lines or unused)
Maybe, if we use a normally resources from JNLP and can load officebean .dll
or .so , the problem whit libjawt will not occur.

* Path Installation LibreOffice on LInux - On Linux unable to use the class
SWT Program to find the program use. Odt and then find your installation
path (like we use on windows). How can we find the installation path of the
program that is opening the files by default?

* Libre 3.6 and 4.0, we found that some parameters are not used anymore in
new versions, such as -- bean, which recommendation? and how can we
differentiate these versions of old?

* Time wait for soffice starts - we need take a Thread.sleep(5000) for wait
soffice really starts .. sometimes when try to call swriter this says that
no have soffice connection .. have another code we can use ? like a while
is connected  or another ?

Such problems are hard to diagnose into the blue, without a complete (yet
minimal), working example (with instructions how to produce from source).
If you can give us that, somebody with a Ubuntu box might have a look,

That rar does not make it obvious what your relevant test code is and how to
build a failing scenario from source.

Problem Trying call LibreOffice from Java

2013-05-07 Thread Fernando Digitaldoc
Hi,
We have a java application that calls the LibreOffice to make creating and
editing files.
That works fine in old 3.2 version when it was a OpenOffice.

Whats wrong in code now? 

In Windows says:  UNO_PATH environment variable is not set (required system
path to the office program directory)

And in Linux says: 
Error 1:
Could not initialize class com.sun.star.comp.beans.LocalOfficeConnection 

Error 2:
Invalid URL connection UNO

We are running that on one applet, but here we make a simple project with
the source.
We are using WriterEditor.java for tests..

https://dl.dropboxusercontent.com/u/30314039/JavaCallLibreOffice.rar

Anyone can help ? Ty :)
