Re: ant problem when building Irmis

[Claude Saunders <saunders@aps.anl.gov>]

Hi Eric,

I'm not sure what the problem is, but it seems to have something to do 
with the java JDK version you have, or perhaps the CLASSPATH you have.

Both javax.crypto and javax.xml.parsers are built into the core JDK 
1.4.2 (but were not in older versions of java). The javax.xml.parsers 
are in rt.jar and the javax.crypto is in jce.jar, both of which are 
distributed with the JDK I get from java.sun.com (for Linux). I wonder 
if you have a JDK from somewhere else, or one which is missing these for 
some reason. I know there was a time when javax.xml.parsers was not 
distributed, and I suppose a European version of java might choose to 
omit javax.crypto due to export restrictions. But I know many others in 
Europe who have built IRMIS without a problem.

I don't use the environment variable CLASSPATH at all. I tested it, and 
apparently ant <javac> uses both the CLASSPATH and the paths specified 
by <classpath> element. I don't know what the precedence is, though. 
Perhaps if you have explicitly specified a particular rt.jar in 
CLASSPATH, this might cause a problem.

Although you should not have to, as a last resort you can download 
xml-apis.jar and jce.jar as separate java extensions I believe. I have a 
copy of xml-apis.jar in irmisBase/db/lib/java. jce.jar is available from 
java.sun.com as JCE package.

In general, IRMIS builds and runs fine with 1.5.x. The only problem with 
1.5.x is that there is some slightly different Swing behavior that seems 
to cause minor problems with the GUI. But nothing significant.

I hope this helps.
   Regards, Claude
