Re: How do others configure classpath? - /Qibm/ProdData/Java400/ext directory question

["Bruce Jin" <brucej@xxxxxxxxxxxxxxxxxxxx>]

There are more than a dozen jar and zip files in my
/Qibm/ProdData/Java400/ext directory but only 4 of them showed up in the JVM
classpath. I used the API "System.getProperty("java.class.path")"   to
retrieve the CLASSPATH in my java program and servlets.

This lists all jar/zip files retrieved from a java program running in
Qshell:

/QIBM/ProdData/Java400/jdk118/lib/jdkptf118.zip
/QIBM/ProdData/Java400/jdk118/lib/classes.zip
/QIBM/ProdData/Java400/ext/IBMmisc.jar
/QIBM/ProdData/Java400/ext/db2_classes.jar
/QIBM/ProdData/Java400/ext/jssl.jar
/QIBM/ProdData/Java400/ext/ibmjssl.jar
/QIBM/ProdData/Java400/jt400ntv.jar
/QIBM/ProdData/Java400/
/qibm/proddata/http/public/jt400/lib/jt400.zip (this came from ENVVAR
CLASSPATH)

This lists all jar/zip files retrieved from a servlet running in WAS 2.03

/QIBM/ProdData/Java400/jdk118/lib/jdkptf118.zip
