Generating font metricss file for Helvetica-Bold, Helvetica and Times-Roman?

["Sheldon Plankton" <sheldon.plankton@gmail.com>]

It looks like if I want to have embedded fonts I need to generate a
"font matrics file".
Here how I have been trying to do that ...

[plankton@dell002 BOOKS]$ cat MakeFontMatrixFile.sh
#!/bin/sh
JAVA_HOME=/usr/java/jre1.6.0_02
JAVA=$JAVA_HOME/bin/java
FOP_HOME=/usr/share/java
CP=$FOP_HOME/fop.jar:\
$FOP_HOME/avalon-framework.jar

#PFM_FILE=/usr/share/texmf/fonts/type1/urw/helvetic/uhvb8a.pfb
PFM_FILE=/usr/share/texmf/fonts/type1/public/lm/lmb10.pfm
$JAVA -cp $CP \
org.apache.fop.fonts.apps.PFMReader -enc ansi $PFM_FILE my_font_matrix_file.xml

... the problem I am having is that lmb10.pfm is not the pfm file for
Helvetic-Bold, Helvetica or Times-Roman.  Where are the pfm files for
these fonts?

Thanks
