Re: Help with Debian solr/jetty install?

[Phillip Farber]

After following Otis' and Thorsten's advice, I still get:
HTTP ERROR: 500 No Java compiler available

running http://localhost:8280/solr/admin out of the Debian solr-jetty 
package.

I have *both* the sun 5 and 6 JDK and JRE installed and both have javac

/usr/lib/jvm/java-1.5.0-sun/bin/javac
/usr/lib/jvm/java-6-sun/bin/javac

I get the same error with JAVA_HOME set to either the sun JDK 5 or 6.

I have made sure to stop and start Jetty so it reads the environment.

% echo $JAVA_HOME
/usr/lib/jvm/java-1.5.0-sun

% echo $PATH
/usr/lib/jvm/java-1.5.0-sun:/usr/lib/jvm/java-1.5.0-sun/bin:/root/local/bin:/l/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

% which javac
/usr/lib/jvm/java-1.5.0-sun/bin/javac

% javac -version
javac 1.5.0_13

% cd /etc/init.d
% ./jetty stop
Stopping Jetty servlet engine: ...jetty.

% ./jetty start

% firefox http://localhost:8280/solr/admin &
HTTP ERROR: 500 No Java compiler available


I see in /etc/jetty/start.config some lines to put tools.jar into the 
classpath:

$(java.home)/lib/tools.jar    ! available com.sun.tools.javac.Main
$(java.home)/../lib/tools.jar ! available com.sun.tools.javac.Main

and noticed that java.home was not defined in this file.  I defined:

java.home=/usr/lib/jvm/java-1.5.0-sun

No change.

I see in /etc/jetty/webdefault.xml JSP servlet definition a note about 
compilers:

The JSP page compiler and execution servlet, which is the mechanism
used by Tomcat to support JSP pages.  Traditionally, this servlet is
mapped to URL patterh "*.jsp".  This servlet supports the following
initialization parameters (default values are in square brackets):

[...]
compiler      Which compiler Ant should use to compile JSP pages.  See 
the Ant documenation for more information. [javac]

I added "compiler" to the definition so in full that looks like:

  <servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
        <param-name>logVerbosityLevel</param-name>
        <param-value>DEBUG</param-value>
    </init-param>
    <init-param>
        <param-name>fork</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>xpoweredBy</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>compiler</param-name>
        <param-value>javac</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>

I still get the error.


Can anyone suggest where I go from here?

Thanks,

Phil

e.g. 

cd ~
vim .bashrc

...
export JAVA_HOME=/home/thorsten/opt/java
export PATH=$JAVA_HOME/bin:$PATH

The important thing is that $JAVA_HOME points to the JDK and it is first
in your path!

Subject: Help with Debian solr/jetty install?


Hi,

I've successfully run as far as the example admin page on Debian linux
 2.6.

So I installed the solr-jetty packaged for Debian testing which gives
 me 
Jetty 5.1.14-1 and Solr 1.2.0+ds1-1.  Jetty starts fine and so does the
 
Solr home page at http://localhost:8280/solr

But I get an error when I try to run http://localhost:8280/solr/admin

HTTP ERROR: 500
No Java compiler available

I have sun-java6-jre and sun-java6-jdk packages installed.  I'm new to 
servlet containers and java webapps.  What should I be looking for to 
fix this or what information could I provide the list to get me moving 
forward from here?

I've included the trace from the Jetty log, and the java properties
 dump 
from the example below.

Thanks,
Phil
