Subject jasper is not working with jikes on windows
Date Sun, 01 Sep 2002 18:45:44 GMT
i tried this with tomcat 4.1.8 to 4.1.10 with JspServlet's config:
        <init-param>
            <param-name>compiler</param-name>
            <param-value>jikes</param-value>
        </init-param>
getting this error:
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


	at 
org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:120)
	at

	at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:240)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
...

in the log i got:
2002-09-01 20:13:09 Compiler jikes
2002-09-01 20:13:10 Error compiling file: 
C:\java\jakarta\tomcat\jakarta-tomcat-4.1.10\work\Standalone\localhost\_\/index_jsp.java 
     [javac] Compiling 1 source file

looking into the code i have found the method getServletJavaFileName() in 
JspCompilationContext:
    public String getServletJavaFileName() {

        if (servletJavaFileName != null) {
            return servletJavaFileName;
        }

        String outputDir = getOutputDir();
        servletJavaFileName = getServletClassName() + ".java";
	if (outputDir != null && !outputDir.equals("")) {
            if( outputDir.endsWith("/" ) ) {
                servletJavaFileName = outputDir + servletJavaFileName;
            } else {
                servletJavaFileName = outputDir + "/" + servletJavaFileName;
            }
        }
	return servletJavaFileName;
    }
...
i guess since outputDir is only checked for "/" and not window's file 
separator "\" the path to the generated jsp becomes wrong.

since i am not really a developer and more a tomcat user i would like to ask 
the tomcat-devs for any ideas (although I would have a simple solution with 
file separator ;-)
thanks
klaus
