Installation

From solution directory execute:

$ mvn clean package

Deploy:

1. Copy services, db, jpa and web jar/war files (declared in the plan file) to $VWS_HOME/repository/usr directory
2. Copy *.property files from etc/properties directory to $VWS_HOME/repository/usr directory
3. Copy etc/plans/greenpages.solution.plan to $VWS_HOME/pickup directory

Deploy (old):

1. Copy the solution/target/greenpages*.par to $VWS_HOME/pickup directory
2. Copy the solution/target/par-provided/*.jar to $VWS_HOME/repository/usr directory

Manifest Creation

Bundlor

• Virgo's Bundlor uses the template.mf file to create the manifest in target/classes/META-INF/MANIFEST.MF
• IMPORTANT - The Maven war configuration MUST reference the generated MANIFEST and ignore the one in src/main/webapp/WEB-INF/
• Added Bundle-Description to the template.mf and MANIFEST.MF files. Once the packaging is done, the resulting packaged MANIFEST.MF files should be have been generated by the Bundlor.
• Changed Bundlor to run in the "process-classes" phase to ensure it is done before packaging to avoid inadvertant overwriting by the static MANIFEST.MF file.
