Thank you once again.  I have one (hopefully last) problem.  

 

LOG:  Exception

LOG:  in thread "main"

java.lang.NoClassDefFoundError: org/apache/xerces/dom/DocumentImpl

       at PGtoXML.OWDBtoXML.<init>(OWDBtoXML.java:19)

       at PGtoXML.PGtoXML.getXmlString(PGtoXML.java:7)

ERROR:  java.lang.NoClassDefFoundError:
org/apache/xerces/dom/DocumentImpl

 

I have installed the xerces xml parser the same way I installed the
PGtoXML jar file.  Is there something else I need to do in order to have
PGtoXML see xerces?  How do I set the classpath to be seen?  I've
already entered:

 

       SELECT sqlj.set_classpath('public', 'xercesImpl');

SELECT sqlj.set_classpath('public', 'xml_apis');

SELECT sqlj.set_classpath('public', 'PGtoXML');

 

Also, you were right; I was running pljava 1.0.0 on the windows box.  I
have replaced it with the latest version, and now both servers are
broken.  But I am sure that once I get this to work it'll be better than
what I used to have.

 

Once again thank you for you help.
