Hello folks,
I have a couple of questions concerning Jo! running as a
.sar-application under Phoenix:
1) There is this passage in the config.xml:
<policy>
<grant code-base="file:${app.home}${/}SAR-INF${/}lib${/}*">
<permission class="java.security.AllPermission" />
</grant>
</policy>
However, when starting Phoenix with avalon-jo.sar I get this message:
java.security.AccessControlException: access denied
(java.io.FilePermission
/usr/local/avalon/apps/avalon-jo/etc/server.properties read))
The file is globally readable in the filesystem. What's wrong here? Is a
security directive missing? But shouldn't Jo! be able to read/write its
own files? Jo! does write to its logfiles, for example.
2) Suppose I get Jo! up and running. Then I want to write a servlet that
basically just deals with incoming requests and loads off the real work
to a custom .sar application that also runs under Phoenix. How could the
servlet communicate with this other .sar-application? Or would I have to
write this other application as a bunch of blocks and integrate it
within the avalon-jo.sar?
Kind regards,
Ulrich
