XML to get you started
Account Configuration
It is recommended for ease of development that you set up a similar configuration
on your own computers so you can do the bulk of your development and testing locally.
You can then FTP the files up to your account for final testing and production
deployment.
See what version of Java, Java Servlet SDK and Java API for XML parsing
Netmar is running. Currently you can see by issuing the following command
at the shell prompt: ls /opt/java (As of April 22nd, 2000, Netmar is
running Java 1.1.8, Java Servlet SDK 2.0, and Java API for XML Parsing 1.0).
You can download Java packages for various platforms from http://www.javasoft.com.
Activate Servlets in your account:
Click here to request that a zone be created in
your account. For this document, we will assume your account name is
account, your zone's servlet repository is located in the ~account/servlets
directory (/users/a/account/servlets), a servlet is launched by http://www.yourdomain.com/js.account/servletname.
Set your servlets directory and any servlets to be readable and executable
by all: chmod ugo+rx filename
If you wish to compile programs in your account, you should add java to your path
by set PATH=(/opt/java $PATH) or by adding it to your set path statement
in your .cshrc file. You will also want to add environment variables to
your .cshrc file: # for Java Servlets and Java API for XML Parsing setenv JAVA /opt/java setenv JAVA_HOME $JAVA/jdk1.1.8 setenv CLASSPATH .:$JAVA/jdk1.1.8/lib/classes.zip:$JAVA/jaxp1.0/jaxp.jar:$JAVA/jaxp1.0/parser.jar:$JAVA/JSDK2.0/lib/jsdk.jar
At the prompt type:
source .cshrc to activate the changes.
echo $CLASSPATH and echo $PATH to see if the changes in your
.cshrc took effect.
which java to see if you are finding the correct java file.
Testing Your Configuration
Once you have your account configured, you can FTP a servlet class file from your
copy of the servlet development kit into your zone and see if you can launch it
from your browser: http://www.yourdomain.com/js.account/servletname .
You can FTP a servlet or XML Java source file to your account and compile it by
javac file.java. You can run a non-servlet Java class by java
file . If you get a "core dump" message, try changing the line
limit coredumpsize 0 to limit coredumpsize 200 and then source your
.cshrc file.
