mapping paths to servlets doesn't work anymore in SP5 ??

[Olaf Klischat]

Hello,

see subject.

I have a small web application which is contained in a WAR-file named
"httpdump.war". Its deployment descriptor (web.xml) maps the servlet
httpdump.HttpDumpServlet to the path /servletpath/* with the following
XML statements:

<servlet>
<servlet-name>HttpDumpServlet</servlet-name>
<display-name>The HTTP Dump Servlet</display-name>
<servlet-class>httpdump.HttpDumpServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>HttpDumpServlet</servlet-name>
<url-pattern>/servletpath/*</url-pattern>
</servlet-mapping>

In weblogic.properties, I have:

weblogic.httpd.webApp.httpdump=httpdump.war

The WAR-file is structured as follows:

$ jar tf httpdump.war
META-INF/
META-INF/MANIFEST.MF
WEB-INF/classes/httpdump/HttpDumpServlet.class
WEB-INF/web.xml
dummy.jsp
$

Now a request like http://host:port/httpdump/servletpath/xyz should be
directed to my servlet, right?

This works flawlessly in WLS 5.1 SP 3. With SP 5, I get the following:

So, it seems the WLS has interpreted the <servlet-mapping> tag in the
DD correctly, but is then looking for the servlet class in the wrong
places..?

My system configuration:

$ java weblogic.Admin t3://localhost:7001 VERSION
WebLogic Build: 5.1.0 Service Pack 5 08/17/2000 07:21:55 #79895

$ uname -a
Linux localhost.localdomain 2.2.14 #1 Wed Aug 16 01:57:42 CEST 2000 i686 unknown

$ java -version
java version "1.2.2"
Classic VM (build 1.2.2-L, green threads, nojit)
$

Any hints?

Thanks,
Olaf

Yes, this is already a known problem in SP5.
Fix will be available in the upcoming service packs.
I guess the workaround is to put servlet classes in servlet classpath.

Sorry about the regression.

Hi,

we jared our servlets up and placed them in /WEB-INF/lib/....jar. The
mapping is working without any problems.
