Torsten, do you know what this means?
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null
Generated servlet error:
[javac] Compiling 1 source file
[javac] use: jikes [options] [@files] file.java...
[javac] For more help, try -help or -version.
[javac] Error: The option "-encoding" is unsupported in this build.
<snip>
I've unzipped the file jikes-1.18-windows.zip to C:\jikes-1.18
I've created the environment variables:
BOOTCLASSPATH=C:\j2sdk1.4.1_01\jre\lib\rt.jar
JIKESPATH=C:\jikes-1.18
CATALINA_OPTS="-Dbuild.compiler.emacs=true"
I've added C:\jikes-1.18\bin to my PATH variable.
I've edited conf/web.xml, adding the init-param "compiler" = "jikes" as
shown below:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>compiler</param-name>
<param-value>jikes</param-value>
</init-param>
<init-param>
<param-name>javaEncoding</param-name>
<param-value>UTF8</param-value>
</init-param>
<init-param>
<param-name>logVerbosityLevel</param-name>
<param-value>WARNING</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
Am I missing anything? I came across something about having to install IBM's
ICU4J. Is this correct?
Thanks
-Dan

a simply way.
don't set CATALINA_OPTS="-Dbuild.compiler.emacs=true"
restart tomcat and request a jsp page with a syntax error like following
BEGIN -----------------------
<% x = 10 %>
END ------------------------
jikes produce this error:
