JSP-pages and reloadable
Hi!
I have a simple question. Is there a way to get Tomcat to handle
JSP-pages the same way it does classes in WEB-INF when you set
reloadable="true" in your Context-element. It is a bit cumbersome to
restart tomcat and apache every time I have made a change to my JSP-page...

Mattias

Change Classes during tests
Posted by Gianluca Gravina <g_...@virgilio.it>.
I sthere a way to change classes (I mean change code and recompile in
.class) in a web-app and see the results without restarting Tomcat??
I usually use "manager/reload" but it wouild be nicer if it can do it
automatically when a request is made.
The reloadable=true in context is set, ... Ideas?
Thanks in advance

It turned out to be a problem related to the dates on the jsp-files. I
was editing files shared with samba to my windows box using WinEmacs.
For some reason the dates on the files did not get updated correcty when
I saved them so I had to 'touch' them in order to get a good date. When
I did that everything worked fine.

Looks like Glenn Nielsen beat me to it. He just added this today.
Thanks Glenn!

I have had that problem before: included jsp's updating but the outer
one not compiling. Why doesn't this feature get added to tomcat?
I know weblogic does it and it is quite an annoyance in tomcat....

I have run into similar problems before. It turned out to be one of two
things. Either I had to force my browser to reload or I was making
changes in a JSP that was an include for another JSP. I am sure you have
tried the first. I don't know if the second is what you are doing, but
if it is, you will need to save the outer JSP so the timestamp changes.
Then both the outer and any included JSPs will be re-compiled. Other

RE: JSP-pages and reloadable

Should be the only way for it to work....
Why don't you try a test page in a new web app.
Goto tomcat's\webapp directory
create a directory called test
create a file in test called test.jsp
place
<%=executing jsp%>
in test.jsp
Navigate to it in the browser http://localhost:8080/test/test.jsp (this
is by default if you have changed your port or the server is on a
different machine it will be different...)
Monitor your work directory for the .java and .class file that will be
created. There should be a tomcat/work/hostname/test/test$jsp.java.
When you change test.jsp and access it again the test$jsp.java should
update.
I know this has been true on all of the versions of tomcat that I have
used. (3.3-4.0.3)
Hope this helps,
Abe

You don't have to restart Tomcat /Apache when the jsp-page is changed.
