Hi folks -- I had this working but moved my server and, in rebuilding
I seem to have whacked something -- using tomcat 3.3.1 and Java HotSpot
Client VM Blackdown-1.3.1_02a-FCS)
have tried both the 1.2.6 and 1.3 builds of jacl
when I try calling tcl from a jsp I get an error like...
javax.servlet.ServletException: unexpected TclException:
tcl.lang.TclException: cannot read resource "/tcl/lang/library/init.tcl"
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:460)
I have tried putting init.tcl all over the place and cannot seem
to let it be seen.
Does anyone have any ideas how I can make the init.tcl visible
to tomcat? (tomcat-3.3.1 btw)
little snipit example would be like...
<html><head> <title>Test eval of tcl code in .jsp</title>
<%@ page import="tcl.lang.*;" %>
</head><body bgcolor="#ffffff"><h1>Test eval of tcl code in .jsp</h1>
Let's try evaluating some tcl code from within a JSP ...
<p>
<%
Interp interp;
interp = new Interp();
interp.eval("package require java");
String result = "";
try {
String s1 = "set a [split {kicker} {}];";
out.println("<p>==================<p>Test #1: Simple split<p>");
out.println("<b>" + s1 + " ==></b><br>");
interp.eval(s1);
result = interp.getResult().toString();
out.println(result);
etc. etc. etc.

Perhaps this post will help: http://sourceforge.net/mailarchive/message.php?msg_id=369779 Also, you might want to try a patch like the following. It is completely untested, but might provide better results in a JSP like env.

ok - neeeeevermind - found the ref to placing the jar's in $JAVA_HOME/jre/lib/ext
and removing form the CP and tomcat containers -- works fine now (even with the
jars in local WEB-INF/lib)

If you could also write up a little description of the problem and the solution, I could add it to the FAQ. cheers Mo |
