Hi Horacio,
I get similar problems (on debian woody) for the deployment of jar-files.
When I start tomcat (with jsvc) everythings fine and the webapp is
startet.
But I would like to unload and load the application with the manager
application. In this case the start of the webapp fails, because
tomcat cannot copy the jar-files (jstl beeing the first of them) into
work/Standalone/localhost/<webapp>/WEB-INF/lib
because it didn't create that dir.
I did a strace analysis which shows, that tomcat
- checks for the existance of .../localhost/<webapp>/WEB-INF/lib
- tries to create this directory and fails (No such file or directory)
(because .../localhost/<webapp>/WEB-INF does not exist)
- checks all paths up to .../localhost/<webapp>/WEB-INF
- finds that the path up to .../localhost/<webapp> exits
and .../localhost/<webapp>/WEB-INF is missing
- ignores this and tries to open the jar-File (for writing)
This fails and an IOException is thrown

Without jsvc it looks pretty much the same, except that the directory is
created as expected.

But I don't see any reason, why the mkdir is left out, when running with
jsvc.
The java-source for this seems to be (WebappLoader.java ~ line 1061)
File destDir = null;
if (absoluteLibPath != null) {
destDir = new File(absoluteLibPath);
} else {
copyJars = true;
destDir = new File(workDir, libPath);
destDir.mkdirs();
}
// Looking up directory /WEB-INF/lib in the context
try {
NamingEnumeration enum = resources.listBindings(libPath);
while (enum.hasMoreElements()) {
Binding binding = (Binding) enum.nextElement();
String filename = libPath + "/" + binding.getName();
if (!filename.endsWith(".jar"))
continue;
// Copy JAR in the work directory, always (the JAR file
// would get locked otherwise, which would make it
// impossible to update it or remove it at runtime)
File destFile = new File(destDir, binding.getName());
log(sm.getString("webappLoader.jarDeploy", filename,
destFile.getAbsolutePath()));
Resource jarResource = (Resource) binding.getObject();
if (copyJars) {
if (!copy(jarResource.streamContent(),
new FileOutputStream(destFile)))
continue;
}
JarFile jarFile = new JarFile(destFile);
classLoader.addJar(filename, jarFile, destFile);
}
so the directory should just be created with destDir.mkdirs().
How can this fail?
I'm using
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)
daemon 1.0
tomcat 4.1.30
on debian woody. The target system where this fails also is some suse
linux. Unfortunately I don't have direct access to this system yet.
Horacios question showed me that this is a problem on debian woody also.
