OpenSAML user discussion

["Kurt Werner" <>]

Hi Brent (and Chad),

I actually had already started down
the retroweaver path, so its good to know that I was at least going in
the right direction.  I weaved openSAML2.1, openWS and xmltooling,
and rebuilt and ran my webapp using those versions.  My webapp now
loads successfully, but I am currently running into the following error.
 Appears the Lock class is very specific to 1.5+ and not supported
through 1.4.  Would you have expected the weaving to have handled
this?  It looks like the code is using syncronized methods, both weaved
and unweaved, so not sure where Lock is getting referenced.

Subject	Re: [OpenSAML] Running openSAML2.1 under JDK 1.4

Just to help you out here, looks like you can do something
like this:

1) grab the Retroweaver dist from: http://retroweaver.sourceforge.net/

2) run something like this for each 1.5 jar you want to weave (paths 
assume you are in the exploded Retroweaver directory):


java
  -cp 
release/retroweaver-all-2.0.5.jar:lib/asm-3.1.jar:lib/asm-commons-3.1.jar:lib/asm-util-3.1.jar

  net.sourceforge.retroweaver.Weaver
  -jar /tmp/xmltooling-1.0.1.jar /tmp/xmltooling-1.01-weaved.jar


There's also an Ant task, you could easily make a little script to do 
it.  Or see our old build.xml (except that that weaved from the source,
the above operates on the compiled jar directly).


HTH,
Brent
