Subject Re: SessionExamples from the examples webapp
Date Wed, 27 Apr 2011 15:25:07 GMT
Hi,

During a good night sleep I realized that I have to compile the modified .java file :-)

This is my current directory:

bml0065:classes administrator$ pwd
/usr/local/tomcat/webapps/examples/WEB-INF/classes


When I do it I am getting the following errors:

<nyissz>

What am I doing wrong ?  

My guess is that I need a -classpath option, so  javac can find all those definitions it needs.
 What should that be on OSX 10.6.6 ?

Thanks ahead,
