Ant in the tomcat and the use of jikes
Jikes is a far faster than the speed of java javac compiler.
Ant integrated approach:
- JIKESHOME environment variable set the path for jikes
- Set ANT_OPTS =- Dbuild.compiler = jikes
- Jikes path will be added to the system in the PATH
Care to distinguish between upper and lower case.
Then all the ant task default jikes, and if you want to use in a single project in the ant, do not add ANT_OPTS environment variables, only need to amend the build.xml in the javac compiler for the label jikes, such as:
<Javac destdir = "$ () build.dir" debug = "true" deprecation = "false" optimize = "false" failonerror = "true" compiler = "jikes">
Jikes values can be set up as follows:
- Classic (JDK 1.1 or 1.2 standards) - javac1.1 and can also be used as an alias javac1.2.
- Modern (JDK 1.3/1.4/1.5 standards) - javac1.3, javac1.4, javac1.5 can be used as aliases.
- Jikes
- Jvc - that Microsoft's compiler
- Kjc - kopi compiler
- Gcj - in the GCC compiler gcj
- Sj - Symantec the java compiler
- Under the existing jvm extJavac decided to use modern or classic mode
In addition there are several additional jikes attribute settings:
Build.compiler.emacs = false
Build.compiler.fulldepend = false
Build.compiler.pedantic = false
Build.compiler.warnings = true
Build.compiler.warnings this attribute best use of labels in the javac nowarn attributes.
Build.properties for the preservation of documents in the build.xml in this call:
<Property file = "build.properties" />
Jikes can use the additional attributes.
Tomcat integrated approach:
As first set JIKESHOME PATH system and in the web application web.xml add:

If you want to use in all WEB use jikes, set environment variables CATALINA_OPTS =- Dbuild.compiler.emacs = true, then open TOMCAT_HOME $ () / conf / web.xml to find:
<servlet>?
????< Servlet-name> jsp </ servlet-name>?
