Hi all,
Our application has been running very well for about 3 years as
a desktop app, and now we're beginning to deploy it as an applet. That also is
working very well, except for one very strange thing.
We have renamed the Pivot .jar files to eliminate the version
number suffix (just for simplicity, since we have gone through several
revisions of Pivot already, and it simplified the installers). The main .jar
file has this as the manifest:
Main-Class: com.ingres.director.pivot.DirectorMain
Class-Path: pivot-core.jar pivot-wtk.jar pivot-wtk-terra.jar jh.jar
commons-logging-api.jar commons-vfs2.jar pivot-charts.jar pivot-jfree.jar
jfreechart.jar jcommon.jar sigar.jar hadoop-common.jar hadoop-auth.jar
hadoop-dfs.jar guava.jar commons-collections.jar commons-configuration.jar
commons-lang.jar commons-cli.jar commons-io.jar slf4j-api.jar slf4j-log4j12.jar
log4j.jar protobuf-java.jar
And the call to "deployJava.js" has this library list:
var libraries = [];
libraries.push("pivot-wtk.jar");
libraries.push("pivot-core.jar");
libraries.push("pivot-wtk-terra.jar");
libraries.push("director.jar");
libraries.push("commons-cli.jar");
libraries.push("commons-collections.jar");
libraries.push("commons-configuration.jar");
libraries.push("commons-io.jar");
libraries.push("commons-lang.jar");
libraries.push("commons-logging-api.jar");
libraries.push("commons-vfs2.jar");
libraries.push("guava.jar");
libraries.push("hadoop-auth.jar");
libraries.push("hadoop-common.jar");
libraries.push("hadoop-hdfs.jar");
libraries.push("jcommon.jar");
libraries.push("jfreechart.jar");
libraries.push("jh.jar");
libraries.push("log4j.jar");
libraries.push("pivot-charts.jar");
libraries.push("pivot-web.jar");
libraries.push("pivot-web-server.jar");
libraries.push("protobuf-java.jar");
libraries.push("slf4j-api.jar");
libraries.push("slf4j-log4j12.jar");
attributes.archive = libraries.join(",");
var parameters = {
codebase_lookup:false,
permissions:"all-permissions",
java_arguments:"-Dsun.awt.noerasebackground=true
-Dsun.awt.erasebackgroundonresize=true -Djnlp.packEnabled=true",
application_class_name:"com.ingres.director.pivot.DirectorMain"
};
var startupProperties = [];
startupProperties.push("language=en_US");
parameters.startup_properties =
startupProperties.join("&");
deployJava.runApplet(attributes, parameters, "1.7");
So, everything works fine and the applet displays the application perfectly,
just like in the desktop version.
But, at some point when we start to deploy a Pivot FileBrowser
I start to see these errors in the Java Console, where it is trying to find the
"pivot-wtk-terra-2.1.0.jar" file. Of course it does not find it, and
eventually realizes that the class is in the "pivot-wtk-terra.jar" file and
everything works. So, the question is: where is it getting the idea to look
for the version-numbered pivot-wtk-terra-2.1.0.jar file? I have found nothing
in any manifest or any other place that references this .jar file name...
Anyone have any clues (I'm assuming this is some kind of
classloader thing, because the code in Resources.readJSONResource is calling
this:
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
right before it gets the error, but I really don't know where else to look.
I have also checked the Java cache and there is no
"pivot-wtk-terra-2.1.0.jar" file there either.
Thanks,
~Roger Whitcomb
