Dreaded No Java compiler available
Greetings,
I am launching an embedded Apache Tomcat 7.0.14, everything except
JSPs are working fine (static resources, servlets, filters, etc). I
have set JAVA_HOME to a location which does have bin/javac and
lib/tools.jar, and otherwise does appear to be a fully working JDK.
However, I take the following exception:
SEVERE: Exception Processing ErrorPage[errorCode=404,
location=/error-pages/404.jsp]

My project has the following Apache Tomcat dependencies (all 7.0.14):
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-util</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-logging-juli</artifactId>
</dependency>
I am not finding any corresponding jasper-compiler or
jasper-compiler-jdt with the 7.x version scheme. Sorry, but what am I
doing wrong?
Thanks,
-Jesse

JDK version? Platform? (Probably not relevant in this case, but it helps to know the full environment.)

The default Tomcat JSP mechanism hasn't used the Java compiler from the JDK for several years now.

Tomcat 7 JSP handling normally uses the Eclipse JDT compiler from lib/ecj-3.6.2.jar; is that jar accessible to the Tomcat classloader in your embedded environment?
Are you trying to run this from an IDE? What happens if you execute the application directly? (IDEs often obfuscate the situation by choosing to use their own configuration settings.)

Thank you, Konstantin! Adding the following solved my issue:
<dependency>
<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>
<version>3.5.1</version>
<scope>runtime</scope>
</dependency>
I am now able to compile my JSPs on the fly, automatically, in Apache
Tomcat. Despite Mark's comments about bulky downloads in the link you
gave earlier, I find it adds only ~1.5Mb to the already dense ~25Mb
executable jar which I'm building.
Thank you,
-Jesse

They do not exist. (Have you looked into zip distribution?)
Latest Tomcat 6 and Tomcat 7 do use the ecj compiler from Eclipse IDE
project directly, without repacking it.
If you are struggling with maven, some discussion of troubles with
downloading ecj is here:
https://issues.apache.org/bugzilla/show_bug.cgi?id=50604#c1
I think you can search for "ecj" in this mailing list archives and
find several discussions there.
