答复: [Tomcat] Error page not work for 400 error.
Thanks Mark,
1. The web.xml is defind in the {$TOMCAT_HOME} /conf ， not in application.
2. I add some walk around code in the ErrorPageSupport.java
3. public ErrorPage find(int statusCode) {
4. log.info("before find, the length of statusPages
is:"+statusPages.size());
5.
6. log.info("in addErrorPage find by status Code code
is:"+statusCode );
7. log.info(Integer.valueOf(statusCode));
8. if ( statusPages.get(Integer.valueOf(statusCode)) == null )
9. log.info("cannot find for "+statusCode);
10. else
11.
log.info("find:"+statusPages.get(Integer.valueOf(statusCode)).getLocation() );
12.
13. if ( statusCode == 400 ) {
14. log.info("%% use custom errorpage");
15. ErrorPage ep =new ErrorPage();
16. ep.setErrorCode(400);
17. ep.setLocation("\400.html");
18. return ep;
19. }else
20. return statusPages.get(Integer.valueOf(statusCode));
21. }
This code was reached but the return was not worked.

No.

No.
What you are asking for is logically impossible.
The request parsing has failed. Therefore Tomcat can't (reliably)
identify the web application the request should be routed to. Therefore
you can't have an application error page generate a response.
If you are using 9.0.6 onwards, the ErrorReportValve can be configured
to return a custom *static* page for any specific error code and/or
Exception.

I tried Maven clean, install etc but the same error keeps coming and I can't continue my work. Those are warnings. There is nothing there that stops Tomcat from continuing. At a guess, you have a JAR file that contains a manifest that defines a class path and the JARs it lists are not present. If my guess is correct, you have a couple of options: 1. Look in the JARs you are using, figure out which one defines a class path in its manifest and configure Tomcat to skip that JAR. 2. Configure Tomcat to skip the JARs it can't find. 3. Disable manifest scanning in the StandardJarScanner Mark - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
