Heh, just in case anyone is ever as stupid as me in teh future:
I realised that I had put catalina-ant.jar into my TOMCAT_HOME\common\lib
directory, as well as my WEB-INF\lib directory... I have no idea why I did
that, but blame youthful stupidity.
Somehow, having catalina-ant.jar in the common\lib directory really messes
with tool.jar - why I don't know.
Anyway, removing the catalina-ant.jar from the conf\lib dir solves
everything!
Cheers

Hi, and thanks for reading this query - it isn't (at least to me)
anything
to do with putting tools.jar into web-inf/lib, or anywhere else, for that
matter.
Here is the problem:
2004-05-22 02:25:00 StandardWrapperValve[jsp]: Servlet.service() for
servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar
from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat
restart.
If using an alternate Java compiler, please check its installation and
access path.

Here is what has been happening:
I am doing a thesis involving using tomcat+hibernate+mysql to create a
web-site that auto-marks web applications.
Using Tomcat ver. 5.
Until yesterday I could fire up tomcat, run my code, make changes to .jsp
and .java files and, without restarting tomcat, see the changes. Yes,
tools.jar, and in fact ALL the necessary jar files for rinning my app are
in the right place. The application has been running smoothly for about 2
months now.
Today I began to use ant (in a java file - by importing
org.apache.tools.ant.*) to deploy .war files in a particular directory
when I wanted to.
To do so appeared to require the use of a manager setting, so I made on
up,
and added it to TOMCAT_HOME\conf\tomcat-users.xml. Here is the entry:
<user username="andrew" password="iyer" roles="manager"/>
Which was put with the other entries.
NOW when I went to the website 1.jsp in TOMCAT_HOME\webapps\thesis
(contents as follows) I got the above "org.apache.jasper.JasperException:
Unable to compile class for JSP" error.
1.jsp:
<%@ page language="java" contentType = "text/html"%>
<%@ page import="org.apache.tools.ant.*" %>
<%@ page import="org.apache.catalina.ant.*" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%
DeployTask deployer = new DeployTask();
deployer.setUsername("andrew");
deployer.setPassword("iyer");
deployer.setUrl("http://localhost:8080/manager";)
deployer.setPath("/demo");
deployer.setLocalWar("C:/struts-blank.war");
deployer.execute();
%>
Not being sure what the problem is, I made 2.jsp, to see if everything
was
going ok, put it in the same dir as 1.jsp, and visited it. Same error as
above, and here are the contents for 2.jsp:
<html>
<body>
moomoo!
</body>
</html>
Which is odd, because if I call the file 2.html and no error appears.
Finally, I started loading my application files to see if anything else
had
gone wrong - my application worked fine. To do so, I go to index.jsp to
log in, log in, play around and exit. No dramas.
I then edited index.jsp (this file worked fine 2 min ago) by hitting
enter
once at the top of the page, and then saving the file. Go to index.jsp
and I get the above error.
It appears to me that this is something to do with a tomcat config
problem
- it might be having trouble recognising .jar files, but I've checked and
all my jar files are where they should be! I suspect it might have
something to do with me adding the manager into tomcat-users, but that
seems pretty tenuous, as this hasn't been noted anywhere else on the web.
I can't see any other possibiliby except maybe timestamp issues?
Before any .jar questions are asked, here is my .jar file list:
.JAR Files in TOMCAT_HOME\common\lib:
ant.jar;
catalina-ant.jar
commons-collections.jar;
commons-el.jar;
commons-pool-1.1.jar;
jasper-compiler.jar;
jasper-runtime.jar;
jmx.jar;
jmx-remote.jar;
jmx-remote-tools.jar;
jsp-api.jar;
mysql-connector-jave-3.1.1-alpha-bin.jar;
mysql-resourcefactory.jar;
naming-common.jar;
naming-factory.jar;
naming-java.jar;
naming-resources.jar;
serlvet.jar;
tools.jar;
.JAR files in TOMCAT_HOME\webapps\thesis\WEB-INF\lib:
cglib-full-2.0.1.jar;
commons-collections-2.1.jar;
commons0logging-1.0.3.jar;
dom.jar;
dom4j-1.4.jar;
ehcache-0.7.jar;
hibernate2.jarl
jaxen-full.jar;
jstl.jar;
jta.jar;
jaxp-api.jar;
jdbc-2_0-stdext.jar;
log4j-1.2.8.jar;
odmg-3.0.jar;
sax.jar;
saxpath.jar;
standard.jar;
xalan-2.4.0.jar;
xerces-2.4.0.jar;
Any help would be greatly appreciated, I really have no idea why my
application is no longer running.
Cheers
Andrew
