Subject JSP on-server compilation: classpath problem?
Date Wed, 08 Sep 2004 18:44:38 GMT

When I deploy a JSP document with Tomcat 5.5.1 without precompiling, I 
get an error message when accessing the corresponding web page.

I can precompile the document without a problem. If I don't precompile, 
the jasper compiler does everything it's supposed to do. The following 
files all exist

$CATALINA_HOME/work/Catalina/localhost/myapp/org/apache/jsp/test_jspx.java
$CATALINA_HOME/work/Catalina/localhost/myapp/org/apache/jsp/tag/web/selection_tagx.java
$CATALINA_HOME/work/Catalina/localhost/myapp/org/apache/jsp/tag/web/selection_tagx.class

For some reason, the JDTCompiler doesn't find the compiled 
selection_tagx.class.
