Eclipse to Java command line

[Srini -]

All

I developed a test program using xerces to parse xml. Under eclipse I
am able to run it. Now I am trying to run from a command line and I
cannot get java to open the xercesImpl.jar.

My dir structure:

top - xercesImpl.jar
+-----bin pdfHello.class

java -verbose -cp xercesImpl.jar -classpath .\:bin\ pdfHello %1

is the command I am using.

I have tried many combinations of specifying the classpath but java
always complains:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/
xerces/parsers/SAXParser
at pdfHello.parseConfig(pdfHello.java:22)
at pdfHello.main(pdfHello.java:47)
Caused by: java.lang.ClassNotFoundException:
org.apache.xerces.parsers.SAXParser

... 2 more

Any clues deeply appreciated.

Cheers, srini

Not sure why you're including the Xerces JAR in your classpath at all, but
regardless, your command line is totally out of line with the documented options:
<http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html>

You shouldn't specify the "classpath" option twice, and Windows doesn't
separate classpath entries with the colon character, but the semicolon.

Tell us what happens when you fix those two things.

Hello

If your class is not in a package and xercesImpl.jar is in the
previous folder, i think the correct line from command line in the bin
folder is :

windows:

java -verbose -cp .;../xercesImpl.jar pdfHello argument

linux:

java -verbose -cp .:../xercesImpl.jar pdfHello argument

many many thanks. i was misled by some clues.

I changed my command as follows:

java -cp xercesImpl.jar;bin pdfHello %1

and now it is working. I think I am beginning to get a hang of it.

Thanks once again, srini
