JspC HOW-TO? (Was precompilations)
OK, I'm stumped! How do I use JspC to precompile a specific (or all of the)
.jsp file(s)?
I've tried the following:
jspc -uriroot c:\sfwr\tomcat\webapps\examples
-webapp c:\sfwr\tomcat\webapps\examples
c:\sfwr\tomcat\webapps\examples\jsp\num\numguess.jsp
and various other tries w/out success....
TIA,
Mike

You do not have to search for any tool.
you can compile the java files using "javac"
and give a mapping in the web.xml for each contexts
ex:
say the file name is test.jsp then an entry like this in web.xml
<web-app>
<servlet>
<servlet-name>jsp.test</servlet-name>
<servlet-class>jsp.test</servlet-class>
</servlet>
<servlet-mapping>
<url-pattern>/jsp/test</url-pattern>
<servlet-name>jsp.test</servlet-name>
</servlet-mapping>
</web-app>
This is automatically done if you use -webinf -webxml options in Jspc.sh/bat files
so all you hae to do is just run jspc.sh/bat with the -webinf -webxml options

Dear Mike,
It might help if you post what kind of error you are getting,
or what happens when you try.
For me,
tomcat.sh jspc -v -d /usr/local/tomcat/work/localhost_8080%2Fcontextname -webapp /usr/local/tomcat/webapps/myapp
works, it converts my *.jsp files to *.java files (which I
understand now contain the servlet source code).
What I'm looking for is a tool to convert the servlet
source code to servlet classes, using the unique-class-name generation
algorithm described in
http://archives2.real-time.com/pipermail/tomcat-users/2000-August/008481.html
so Tomcat doesn't have to do this work itself when it starts.
Is there such a tool? Or has anybody else run into Tomcat going into
500 server errors while trying to compile JSP pages under heavy load,
and if so, how did you deal with it, please?
Yours Sincerely,
Aleksey Tsalolikhin
