Hi,
in our deployment scripts we precompile jsps for live deployment.
However, we are in the process of switching from 5.0.x to 5.5.16 and
the precompilation fails.
I've searched the net and checked the 5.5 docs but haven't found any hints.
Here's the exception:
[EMAIL PROTECTED]:~/bin/testsystem$ ant -f build_web.xml

suspicious java.home property seems to point to the jre, whether
system JAVA_HOME variable point to the jdk:
/usr/local/java/ -> jdk1.5.0_06_32bit
I've checked the source code and found that the code in
org.apache.jasper.JspCompilationContext.createCompiler(JspCompilationContext.java:224)
tries to load the JDT or JAVAC compiler by name. Is it a classloading issue?
Thanx in advance
regards
Leon
