That works!! Thanks very much for your help. Really appriecated.

I just got tomcat 5.5.7 setup and just did my testing servlet. The path to access the servlet is:

http://localhos:8080/servlet/HelloWorld

Thanks for your reply.

I have done what you told me: having "/testWml.html" in the url-pattern in web.xml.

I also have debug statements in the doFilter() but when I access http://server:8080/imsld/COMP200/testWml.html, there is nothing printed out.

Tomcat is not recognizing the url-pattern. Has anybody have the similar problem? Any solution?

Thanks.

Hi all,

I am trying to use a filter in Tomcat 4.1.30 (servlet 2.3 compatible). My problem is in the web.xml at the url-pattern tag.

I have the following filter and filter mapping:

<filter>
<filter-name>transcoderFilter</filter-name>
<filter-class>com.cj.h2w.transcoderFilter</filter-class>
<init-param>
<param-name>dir</param-name>
<param-value>/home/bwoo/workspace/imsld/COMP200_wml</param-value>
</init-param>
<init-param>
<param-name>url</param-name>
<param-value>http://192.168.2.6:8080/imsld/COMP200</param-value>;
</init-param>
</filter>
<filter-mapping>
<filter-name>transcoderFilter</filter-name>
<url-pattern>testWml.html</url-pattern>
</filter-mapping>

However, the filter will not startup and give the following exception:

SEVERE: End event threw exception
java.lang.reflect.InvocationTargetException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...
Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> testWml.html in filter mapping
at org.apache.catalina.core.StandardContext.addFilterMap(StandardContext.java:1509)

But why? I have read the Sun's Servlet 2.3 Spec and it says it's possible to specify whole file name to match, but it's not working at all. Is it a bug in Tomcat 4.1.x?

Thanks very much.
