Hey folks... I'm having a real pain of a problem here... vital stats:
JRE 1.6.0-b105 (JDK 6)
Tomcat 6.0.10
I have a filter that compiles fine but will not initialize... error that
appears on Tomcat startup:
Apr 2, 2007 1:04:38 AM org.apache.catalina.core.StandardContext filterStart
SEVERE: Exception starting filter MasterControlFilter
java.lang.NoClassDefFoundError: javax/servlet/Filter
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
at
java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)
at java.net.URLClassLoader.defineClass(URLClassLoader.java:260)
...and so on...
The filter is contained within a JAR in my webapp's WEB-INF/lib
directory. I've verified the filter is in the correct package, and that
web.xml specifies the correct class name.
I've spent about an hour Googling, and I've found numerous references to
seemingly similar problems, but no answers... I've verified that there
is no other servlet-api.jar floating around... I did notice a number of
places that said servlet-api.jar should be in CATALINA_HOME/common/lib,
but it's in CATALINA_HOME/lib in my installation (that's how it came out
of the distro)... I assume that's just some old documentation I'm
finding, but maybe not?
For completeness, environment variables I have:
CATALINA_HOME=k:\tomcat6010
JAVA_HOME=c:\java15
Path=c:\java15\bin;k:\tomcat6010\bin;x:\classes\apache-ant-1.7.0\bin
...NO classpath defined...
I don't think there's any other relevant env vars. Can anyone point me
in the right direction? I'm pretty well stuck at the moment until I get
this resolved. Thanks!
Frank
