Bug ID: 55973
Summary: Failure to parse MergedWebXml when validation is
enabled in Jasper
Product: Tomcat 7
Version: trunk
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org
Reporter: knst.koli...@gmail.com
See e-mail on dev@:
"[7.0.x] Document is invalid: no grammar found. for MergedWebXml in Jasper"
http://markmail.org/message/jbnbmezbdegoufm5
This issue affects the current TC7 code (7.0.51-dev), since the following
commit: http://svn.apache.org/r1552826
It does not affect 7.0.50.
(The error is generated internally, but the list of error is not checked, so it
is effectively ignored).
Steps to reproduce:
1. Enable validation, by adding the following line to conf/catalina.properties
org.apache.catalina.STRICT_SERVLET_COMPLIANCE=true
2. Set JAVA_HOME variable to point a Java 6 JDK. I am using 6u45.
3. Start Tomcat
4. Go to http://localhost:8080/
Expected: index.jsp of the ROOT web application
Actual: Error 500, with the following message in localhost.DATE.log file:
08.01.2014 1:20:11 org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [jsp] in context with path [] threw
exception [org.apache.jasper.JasperException: XML parsing error on file
org.apache.tomcat.util.scan.MergedWebXml: (line 2, col 9)] with root cause
org.xml.sax.SAXParseException: Document is invalid: no grammar found.
