Hello Sam,
thank you for your notice,after adding
import org.xml.sax.SAXException;
the ExampleFO2PDF.java compilation was successfull,
but the FopServlet.java failed:
% javac FopServlet.java
FopServlet.java:114: unreported exception org.xml.sax.SAXException; must be
caught or declared to be thrown
fopFactory.setUserConfig(new File("/opt/coolstack/fop/conf/fop.xconf"));
^
1 error
Here below is the modofication in my FopServlet.java
import org.apache.avalon.framework.configuration.Configuration;
import org.apache.avalon.framework.configuration.DefaultConfigurationBuilder;
import org.xml.sax.SAXException;
[...]

I'm sorry, I didn't mean to split this into 2 emails. If you don't have the
SAXException included, you need to import
org.xml.sax.SAXException
in your program.

Hi Al,
Have you made sure to include the SAXException in your imports?

Hello Andreas,
I've tried to replace the FOPException by SAXException as you said,
but it didn't work:
//public void convertFO2PDF(File fo, File pdf) throws IOException,
FOPException {
public void convertFO2PDF(File fo, File pdf) throws IOException,
SAXException {
fopFactory.setUserConfig(new File("/opt/coolstack/fop/conf/fop.xconf"));
OutputStream out = null;
try { ...}
Compilation: www-slave:root>javac ExampleFO2PDF.java

throws IOException, SAXException {

The same for the FopServlet.java program from the FOP 0.95 distribution :
In the directory {fop-dir}/src/java/org/apache/fop/servlet
I replaced FOPException by SAXException, and put there the configuration as
following:
------------------------------------------------------------
vi FopServlet.java
[...]
protected void configureFopFactory() {
fopFactory.setUserConfig(new File("/opt/coolstack/fop/conf/fop.xconf"));
//Subclass and override this method to perform additional configuration
}
[...]
protected void renderFO(String fo, HttpServletResponse response)
//throws FOPException, TransformerException, IOException {
throws SAXException, TransformerException, IOException {
When I compiled this servlet: javac FopServlet.java
------------------------------------------
I've got error:
FopServlet.java:184: cannot find symbol
symbol : class SAXException
location: class
org.apache.fop.servlet.FopServlet
throws SAXException, TransformerException, IOException {
^
FopServlet.java:242: cannot find symbol
symbol : class SAXException
location: class org.apache.fop.servlet.FopServlet
throws SAXException, TransformerException, IOException {
^
2 errors
Have you got any idea, how to compile the FopServlet.java using a configuration
?
btw, the FopServlet.java attached to the mail.
thank you,
Al

That's normal, and basic Java. FopFactory.setUserConfig() can throw a checked
SAXException, which means you either have to add it to the 'throws' clause to
the method signature, or you need to try-catch it explicitly.
Make it:
convertFO2PDF(...) throws IOException, SAXException {
Replacing FOPException with SAXException is sufficient, since a FOPException is
itself a
SAXException.
HTH!
Andreas
