[jira] [Created] (CONFIGURATION-478) Cannot write to files within
an app server directory
Cannot write to files within an app server directory
----------------------------------------------------
Key: CONFIGURATION-478
URL: https://issues.apache.org/jira/browse/CONFIGURATION-478
Project: Commons Configuration
Issue Type: Bug
Components: Build
Affects Versions: 1.8, 1.7
Environment: Java , Linux, Jboss
Reporter: raghutpk
Hi
This issue is really grappling me. I use Apache commons configuration to read the configuration for my application. I expose my configuration through a jmx client so that I can change the configuration at runtime and would like to persist the changes to the original load form.
I have multiple configuration sources so I use a CombinedConfiguration object to read in my config.xml file. I have wrapped custom logic and rules to save the confgiuration to the persistent store.
I use Jboss AS5 to deploy my application.
All is well when I have configuration files in the filesystem outside $JBOSS-HOME/server/default/deploy. I am able to read fine and write back to the config files fine too.
but the problem is when I bring in the Config files in the following directoy $JBOSS-HOME/server/default/deploy/{application-name}/..
I can read the configuration fine, but when I try to write the configuration back to the persistent store using the save method of the respective configuration(like PropertiesConfiguration & XMLConfiguration) using a jmx client(I also tried to harcode and save within code immediatly after reading my configuration). I keep getting the follwing exception :
java.net.UnknownServiceException: protocol doesn't support output
at java.net.URLConnection.getOutputStream(URLConnection.java:792)
at org.apache.commons.configuration.DefaultFileSystem.getOutputStream(DefaultFileSystem.java:113)
at org.apache.commons.configuration.AbstractFileConfiguration.save(AbstractFileConfiguration.java:461)
at org.apache.commons.configuration.AbstractFileConfiguration.save(AbstractFileConfiguration.java:402)
at org.apache.commons.configuration.AbstractFileConfiguration.possiblySave(AbstractFileConfiguration.java:737)
at org.apache.commons.configuration.AbstractFileConfiguration.clearProperty(AbstractFileConfiguration.java:784)
at org.apache.commons.configuration.AbstractConfiguration.setProperty(AbstractConfiguration.java:483)
at org.apache.commons.configuration.AbstractFileConfiguration.setProperty(AbstractFileConfiguration.java:774)
......
Please throw some light on the exception because it is helping me nowhere in understanding the issue
If I am able to read it, I should also be able to save it back..but it is not happening within JBOSS directory(I can only read). Moment I shift my configurations outside that to a different place in the Filesystem say /home/../Config and also keep the config.xml(containing the reference to the Configuration sources)it is perfectly working fine.
This is being a blocker for me. I may have completely misread the scenario, so please throw light on the same if I am missing anything or more details are needed.
Following is the piece of code used to read the configuration :
...
builder.setFile(new File(Path to CONFIG_DIRECTORY +
CONFIG_DEFINITION_FILENAME(config.xml)));
CombinedConfiguration combinedConfig = builder.getConfiguration(true);
sample config.xml file :
<?xml version="1.0" encoding="ISO-8859-1"?>
<configuration>
<header />
<override>
<properties
fileName="db.properties"
autoSave="true" config-name="properties1" />
<properties
fileName="jms.properties"
autoSave="true" config-name="properties2" />
<properties
fileName="test.xml"
autoSave="true" config-name="properties3" />
<xml fileName="gui.xml"
autoSave="true" config-name="xml1" />
</override>
<additional />
</configuration>
Following is sample code used to write back updated values to the persistent store :
xmlConfig = (XMLConfiguration) combinedConfig.getConfiguration("configuration source name");;
if (xmlConfig.containsKey(key)) {
try {
// Update the value.
xmlConfig.setProperty(key, value);
xmlConfig.save();

[jira] [Commented] (CONFIGURATION-478) Cannot write to files within

Oliver Heger commented on CONFIGURATION-478:
--------------------------------------------
Can you log the URL of the configuration you want to save: xmlConfig.getURL() ?
Without knowing too many details about JBoss's deployment mechanism, I assume that your application is not directly executed from the deploy folder, but copied into a working directory. Therefore, you probably end up with a URL pointing to a file in a virtual JBoss file system. That this file cannot be written is pretty clear.
In general, I do not think that it is a good idea to manipulate content of an application folder which has been deployed to a server. The directory is under control of the application server, and changing it - if possible at all - may have undesired side effects.
Further, I doubt that this issue is specific to Commons Configuration. You can check whether you are able to read, manipulate, and save any other file from your application directory.
