Moving .bxml outside the package its called from.

[David Heard <da...@gmail.com>]

Hello All,

I am new to apache-pivot although I do work with Spring MVC & Hibernate.

Before I pose this question I did go through the archive, from Jan. 2011 to
current and I did not see an answer, and I did try Stackoverflow as well.
What I would like to do is move the .bxml files to a separate directory -
for example: /xml in the project.

eclipse is the IDE (Keppler) and the plugin is installed.

To make this shorter I'll use the excellent example of HelloBXML and just
the relevant snippet of code;

@Override public void startup(Display display, Map<String, String> arg1)
throws Exception {
       BXMLSerializer bmxlSerializer = new BXMLSerializer();
       window = (Window) bmxlSerializer.readObject(HelloBXML.class,
"xml/hello.bxml");
       window.open(display);
       }

I can get hello.bxml to load if I include it in the classpath as
com.dwh.pivot.tutorial.xml or by itself as hello.bxml in
com.dwh.pivot.tutorial where HelloBXML.java resides.

When I tried creating the xml directory and calling hello.bxml from it I
got the error: " I get an java.lang.IllegalArgumentException: could not
find resource "/xml/hello.bxml". "

I also tried using window = (Window)
bmxlSerializer.readObject(getClass().getResource("xml/hello.bxml"));
and I get a different error,  "java.lang.IllegalArgumentException: location
is null."

After a little thought, I tried creating a separate package named xml and
added hello.bxml to it. I received the same location is null error.

What I would like to know is if it is possible to separate the files like
that using pivot? My reasoning is I am trying to isolate the gui portions
from the data or model. Maybe I am way out in left field and over thinking
it.

Thank you for taking time to look at this, if I am off base let me know :)
I won't take offense. If I missed something somewhere point me at it and
smack my hand.

Peace,
-Dave

I don't have a full answer for you, but I have a pointer. Note that
BXMLSereializer.readObject() uses Class.getResource() to find the file.
This StackExchange question may be helpful:

Sorry not to give you a better answer, but its Friday night and I've got
beer to drink =)

Hi David,
     Welcome to Pivot!  Hopefully we can help you get some useful work 
done with it....
     So, the BXMLSerializer class isn't doing anything particularly 
fancy to load a file.  It will be calling (under the covers) the 
HelloBXML.class.getResource("xml/hello.bxml"...), which is just standard 
Java resource stuff.  If you are running out of a .jar file, then the 
.bxml file would need to be in the .jar where the HelloBXML.class file 
is and accessible from the com/dwh/pivot/tutorial/xml path.  The code in 
our application has lots of BXML resources located in various 
directories (within the .jar file), all underneath the main class 
location, so yes, it is definitely possible.  You just need to follow 
the standard rules for locating Java resources.
     That first error you show ("could not find resources 
"/xml/hello.bxml") (if that is exactly the message) would have to have 
come from using a path of "/xml/hello.bxml", which is probably not what 
you want.  The code you're showing (with the path of "xml/hello.bxml") 
should work if the file is placed (as I said) in the 
com/dwh/pivot/tutorials/xml directory.
     Bottom line, this isn't anything unique to Pivot -- we just use the 
class' package location as a starting point for locating the resource 
using the standard Java mechanisms.

HTH,
~Roger Whitcomb
