JSP won't compile... error contains no info......

hi,

I've been working on this project for about two weeks now, all of a sudden since last Sunday evening my JSP's won't compile (sometimes what happens is JSP loads fine, but if I reload it I get this error..)
usu when a JSP won't compile it's a syntax error and error-msg says what the syntax error is, but this time error-msg is not giving me any info whatsoever as to why JSP is not compiling:

org.apache.jasper.JasperException: Unable to compile class for JSP
org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:97)

org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:346)
org.apache.jasper.compiler.Compiler.generateClass(Compiler.java:414)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:472)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:451)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:439)
org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:511)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:295)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

further down it says:

Compile failed; see the compiler error output for details.

.....

The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs.


------------------------------------------

this is on my website (in my local Tomcat JSP's compile fine..), I don't know where logs files are, and I don't know where to look for "compiler error output"... if there's a syntax problem, shouldn't it say what it is? (no unusual API's or anything, that I might have forgotten to upload; as I mentioned above, I started getting this error only two days ago; before that JSP's were compiling fine..)

thank you........
