RE: Accessing External Java Library

Hi Michael,

I tried the -TJ flag but it didn't seem to provide me with any more
information:

C:\Documents and Settings\cbourne.LATITUDE-D620\My Documents\PGPJava>java -cp
c:
\ColdFusion8\javapgp -jar saxon8.jar -TJ test.xml test.xslt
Error at xsl:value-of on line 12 of
file:/C:/Documents%20and%20Settings/cbourne.
LATITUDE-D620/My%20Documents/PGPJava/test.xslt:
  XPST0017: XPath syntax error at char 58 on line 12 in {...exicon", "test
for",
 " ", "...}:
    Unknown system function pgp.encrypt()
Failed to compile stylesheet. 1 error detected.

Try the -TJ flag, which will help to distinguish between the different
reasons for not finding the method you want to call. The most common reasons
are:

class not on classpath (often caused by using -jar on the command line,
which means there is no classpath)

class not public

method name wrong

method not public

method not static (when the call assumes it will be)

method arguments have wrong type
