OpenSAML user discussion

Here are some steps when using Retroweaver:


Steps)

1) Start by getting the lastest versions
of the openSAML libraries.  You will need opensaml-#.jar, openws-#.jar,
and xmltooling-#.jar.  Place these files into a directory (e.g. C:\Weaver)

        Download URL = "http://shibboleth.internet2.edu/downloads/maven2/org

2) Download the latest version of RetroWeaver and unzip to your hard disk (e.g. C:\Dev\)

        Download URL = "http://retroweaver.sourceforge.net/index.html

3) Run the following command from within the retroweaver home directory (e.g. C:\Dev\retroweaver-2.0.5).  You may need to update the supporting jar file versions listed below if they have changed since version 2.0.5 of retroweaver.  

java -cp release\retroweaver-all-2.0.5.jar;lib\asm-3.1.jar;lib\asm-commons-3.1.jar;lib\backport-util-concurrent.jar;lib\asm-util-3.1.jar net.sourceforge.retroweaver.Weaver -jar C:\Weaver\opensaml-2.1.0.jar C:\Weaver\opensaml-2.1.0-jdk14.jar

This will take your opensaml-2.1.0.jar file as input.  Once the weaving process is complete it will output opensaml-2.1.0-jdk14.jar.

Repeat this process for the openws and xmltooling jar files.

4) Each run will count the number of files that were weaved.  You should end up with 3 new jar files that are now compatible under Java JDK 1.4.  You can now include these new jars within your web application.

5) If you want to confirm that the jar files are truely 1.4 compatiable there is an -verifyrefs option that can be added to the command above.  You will also need to include quite a number of supporting jar files along with your 1.4 runtime.  More info can be found in the /docs directory of the retroweaver install.

6) There is also a GUI front end to Retroweaver, but it only runs against class files and not jars.  Again, see documentation for more details.

7) Finally, when running your web application you will need to include the following supporting jar files.
       
        retroweaver-rt-2.0.5.jar and backport-util-concurrent-3.1.jar


Sample Run:
>> java -cp release\retroweaver-all-2.0.5.jar;lib\asm-3.1.jar . . . .
[RetroWeaver] Processing 510 classes
[RetroWeaver] 510 classes weaved.

> How can I get openSAML2.0 library for JDK 1.4?

You'll have to manually attempt to rebuild it all with retroweaver or some
other downleveling tool. I don't think there's going to be a prebuilt
version for that any time soon.

JDK 1.4 is EOL as of this October. Deploying something on it today is not
really a sensible thing to do IMHO.
