Tomcat Jasper Compiler ant task not working - missing tag lib
validator
Hi,
I have a large java jsp and servlet web application. Started about 20
years ago and still going strong. It uses an ant build process. One of
the ant tasks is to compile all the .jsp files. This is done using the
following task:
<jasper validateXml="false"
uriroot="cc"
addWebXmlMappings="true"
webXmlFragment="CCjaspercompiler/WEB-INF/web.xml.generated"
strictQuoteEscaping="false"
classpath="${classpath}"
outputDir="${jspOutput}" />
This used to work on a tomcat 7. A while ago, we upgraded to 8.5.15 and
I think at that stage, the above ant task stopped working.
When running the ant task, I get the following error:
[jasper] Jul 07, 2021 11:22:32 PM
org.apache.tomcat.util.scan.StandardJarScanner scan
[jasper] WARNING: Failed to scan

It seems like the ant task is trying to scan the full classpath as a
single "file:" specification. Or something like that. When I output
(echo in ant) the ${classpath}, it does not include the "file:" part at
the start. However within the jasper task, that gets added to the
classpath attribute on the jasper ant task. I'm not sure if this is
relevant or if there is some other underlying issue.
I realize this is maybe sort of an ant question and not tomcat, but I
think the issue arose when upgrading tomcat, so I'm posting to this list
as a starting point.
Any suggestions you have would be greatly appreciated.
Thanks!
Alex.

Re: Tomcat Jasper Compiler ant task not working - missing tag lib validator
Posted by Builder Lynx Demo <bu...@gmail.com>.
Hi Chris, Mark,
Returning to an old thread...
I was able to figure this out. My application uses axis2 for web
services. Asix2 has .JSP files in:
WEB-INF/views/admin
WEB-INF/include
These .jsp files are the ones causing the problem. I'm not sure why.
My application doesn't use taglibs itself. The axis2 package does for
these files. So it seems like axis2 doesn't include the
javax/servlet/jsp/tagext/TagLibraryValidator.java, nor is my ant task
able to find it in tomcat.
I was able to fix the problem by removing the axis2 .jsp files from the
japser compile process. Not quite ideal.
Mostly just sending this into the list for someone else's benefit in the
future.
Thanks for your help.
Alex.

I suspect multiple instances of the same class. I don't see anything
obvious in the class path that was cause that but I do see instances of
what looks like duplicate JARs. For example: ecj.jar and jdt-compilier.jar

Hi Chris, Mark,
Thank you for pointing that out. I never would have guessed that.
Updating the separator addresses that issue. However now the jasper
task throws an exception:

The class "javax/servlet/jsp/tagext/TagLibraryValidator" is in the file
{$TOMCAT_HOME}/lib/jsp-api.jar
I have verified that the jar is in the ant's <jasper classpath="...">
value. For reference the full classpath variable is below.
It seems the not found class is not the "TagLibraryValidator" (I'm
pretty sure that is on the classpath). Maybe it is some other class
that "TagLibraryValidator" references? Any idea how to determine
exactly which class can not be found?
Thanks
Alex.

Or, better yet, have ant compute the "classpath" value for you by
building a path-like structure, like this:
<jasper validateXml="false"
uriroot="cc"
addWebXmlMappings="true"
webXmlFragment="CCjaspercompiler/WEB-INF/web.xml.generated"
strictQuoteEscaping="false"
outputDir="${jspOutput}">
<classpath>
<pathelement location="${webapp.path}/WEB-INF/classes"/>
<fileset dir="${webapp.path}/WEB-INF/lib">
<include name="*.jar"/>
</fileset>
</classpath>
</jasper>
Then you can port it between systems and not worry about the separator.

It looks like the Windows path separator ";" is being used rather than
the Linux path separator ":". Try changing those semicolons to colons.
