RE: Newbie getting NoClassDefFoundError when running servlet
The .war is incomplete. You will need to add fop.jar (plus others) to the
WEB-INF/lib directory.
I also had problems with batik.jar, and ended up removing some of the sax
classes.
Good luck

Subject: Newbie getting NoClassDefFoundError when running servlet
I am getting the error message "java.lang.NoClassDefFoundError:
org/apache/fop/apps/XSLTInputHandler" when I try to run fop as a servlet.
Operating System: Windows 98
FOP Version: fop-0.20.4
Tomcat Version: 4.04
I have copied the file fop.jar (that contains "XSLTInputHandler" class) to
directories on my path, and to several Tomcat subdirectories all to no
avail.
The story:
1. Downlaoded fop-0.20.4 & unzipped it into a sundry directory. Got fop.bat
to convert a FO to PDF
2. Copied fop.war to Tomacat/webapps
3. Started Tomcat. Tomcat reported a problem:
"org.xml.sax.SAXParseException:The content of element type "servlet-mapping"
must match "<servlet-name,url-pattern>"". I found the problem in the
web.xml supplied with this relase (see below for the solution if you have
the same issue)
4. Fixed web.xml and started Tomcat again
5. In my browser, tried opening http://localhost:8080/fop/fop?fo=/article.fo
<http://localhost:8080/fop/fop?fo=/article.fo> ("article.fo" is my FO file
located in Tomcat/webapps/Root)
6. Got a ton of error messages, at the root of which seems to be
"java.lang.NoClassDefFoundError: org/apache/fop/apps/XSLTInputHandler".
Attempting the same url again, Tomcat tells me the servlet is currently
unavailable. I have to restart Tomcat to try again.
Can anyone tell me where I am going wrong?
Thanks!

ps Here is the solution to the web.xml problem:
The error message is saying that in a <servlet-mapping> element it is
expecting to see one <servlet-name> and one <url-pattern>. In the web.xml
that installed itself on my system, I had the entry:
<servlet-mapping>
<servlet-name>
Fop
</servlet-name>
<url-pattern>
/fop
</url-pattern>
<url-pattern>
/servlet/fop
</url-pattern>
</servlet-mapping>
There are two <url-patterns>'s for one servlet name. The solution is
simple. Create an additional <servlet-mapping> and put one of the
<url-patterns> in it as below:
<servlet-mapping>
<servlet-name>
Fop
</servlet-name>
<url-pattern>
/fop
</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>
Fop
</servlet-name>
<url-pattern>
/servlet/fop
</url-pattern>
</servlet-mapping>

That's faq actually, fo syntax has changed in xsl recommendation, now masters
have master-name attribute and master references have master-reference.

My interpretation is:
1. Evaluate each column width with proportional-column-width() set
to zero.
2. Subtract the sum of 1. from the table width.
3. Divide the result of 2. by the sum of all arguments of the
proportional-column-width() functions. The result is the proportional
width.
4. Evaluate the column widths again, this time
proportional-column-width(X) returning X times the proportional
width
This means:
- a table with
<fo:table-column column-width="proportional-column-width(1)"/>
<fo:table-column column-width="proportional-column-width(1)"/>
has two columns of equal width.
- a table with
<fo:table-column column-width="proportional-column-width(1)"/>
<fo:table-column column-width="proportional-column-width(2)"/>
has two columns, the second twice as wide as the first.
- a table with
<fo:table width="100mm">
<fo:table-column column-width="proportional-column-width(1)"/>
<fo:table-column column-width="40mm"/>
<fo:table-column column-width="proportional-column-width(2)"/>
has columns of 20mm, 40mm and 40mm width
- a table with
<fo:table width="100%">
<fo:table-column column-width="proportional-column-width(1)"/>
<fo:table-column column-width="40mm"/>
<fo:table-column column-width="proportional-column-width(1)"/>
has a the second column of 40mm width and rest width equally distributed
between the first and the third row.
- a table with
<fo:table width="100mm">
<fo:table-column column-width="proportional-column-width(1)"/>
<fo:table-column column-width="40mm+proportional-column-width(1)"/>
hastwo columns of 30mm and 70mm width.

20_0_1 vs higher version
Posted by Petr Hanek <pe...@kctdata.cz>.
Hi,
I have simple xml and xsl file.
It works on fop 0_20_1 but it doesn't run on higher version (0_20_3,
0_20_4).
I see this error:
[ERROR] org.apache.fop.apps.FOPException: 'master-reference' for
'fo:page-sequence'matches no 'simple-page-master' or 'page-sequence-master'
Thanks
