hsqldb incompatibilty in admin search

Karl Zilles — Sat, 18 Jan 2003 03:36:02 -0000

Error using hsqldb. Works correctly under postgresql.

From
http://localhost:8080/melati/org.melati.admin.Admin/contacts/Main

Click the maginfying glass icon toward the middle of
the screen. Type anything in the "name" field. Hit
search.

I get the following exception thrown, probably because
of the "REGEXP" term in the sql:

org.melati.poem.ExecutingSQLPoemException: Executing
SQL ...
SELECT "id" FROM "contact" WHERE "name" REGEXP 'sdf'
ORDER BY "name", "owner"
Error reported by jdbc driver

org.melati.MelatiServlet.properties not found under Tomcat4

James Michael Wright — Sat, 04 Jan 2003 03:19:20 -0000

Install melati.war under Tomcat. E.g. in

/var/tomcat4/conf/server.xml

under Linux have:

...

where someDir/ROOT.war is a symlink to the latest
melati.war and melati is a virtual host defined
in /etc/hosts (or C:\WINDOWS\HOSTS ?)

service tomcat4 restart

Point your browser at http://melati:8080/

Click "database administration system" and the
error is:

javax.servlet.ServletException:
org.melati.util.ConfigException: The file
org.melati.MelatiServlet.properties could not be found.
Is it in your CLASSPATH? Full Error:
java.io.FileNotFoundException:
org.melati.MelatiServlet.properties: is it in CLASSPATH?

plus a stack trace. But we don't need that here
because

http://localhost:8080/tomcat-docs/class-loader-howto.html

explains that both classes and resources should be
placed under /WEB-INF and that the web application
class loader only looks under here. Hence why the file
is not found.

The 2.3 servlet spec is less clear to me because it
says in section 9.4 "recommended, but not required"
and suggests in section 9.5 that WEB-INF is for
stuff that should not be directly visible to a
browser rather than for stuff that *should* be
visible to a class loader.

Nevertheless I think both *.properties and
*.wm should be classified as resources rather
than static content and therefore go under WEB-INF.
(Project iVr would appear to agree.)

This can be arranged by changing one element in build.xml
from <fileset> to <classes>. Namely, in the "war" target:

<classes dir="${built.src}">
<patternset>
<include name="**/*.properties"/>
<include name="**/*.wm"/>
</patternset>
</classes>

Jetty works either way. This fixes the tomcat installation.
Don't know about JServ.

An alternative may be to configure a class loader for the
Tomcat web application, if there is a good reason for not
doing the above.

$contact.isIn($contact) undefined

James Michael Wright — Fri, 03 Jan 2003 04:06:00 -0000

ant go

Click:
Examples
Contacts Database
Add New Contact

This causes:

org.webmacro.PropertyException: Evaluation warning:
WARNING: #if: Error evaluating condition:
org.webmacro.PropertyException$NoSuchMethodException:
No public method isIn(property:category) on variable
$contact of class org.melati.example.contacts.Contact

The reference is in:

org/melati/example/contacts/ContactView.wm

The method is not defined in:

org/melati/example/contact/Contact.java

Cannot compile melati

jdk1.3 .1 (sun)
Build Environment Netbeans ( www.netbeans.org)
Machine Linux Redhat 7.1

Changed this to...

PoemTransaction p = database.poemTransaction(index);
Connection c = p.getConnection();

return new TransactionStuff(c);

Now

PoemTransaction p =
