Extracted ear/war/jar file location in JBoss

How can I find out in runtime where JBoss extracted my ear/war/jar file?
I have a file inside my ear/war/jar file and I need to know the location of the file. I know that it is in the tmp/deploy directory but I need the exact application temporary name.

You can take out the common classes and bundle them in a jar library that can be bundled directly in APP-INF/lib (or library directory defined by <library-directory> in applicaton.xml if you are using JEE5 / WLS 10). Is it possible to do this re-arragement?

Putting unix utility visible version info into ear, war, jar files?

I would like to be able to use some unix utility (or java itself without a separate program) to display my version information for jar-like artifacts: ear, war, jar.
In other words, when I build one of these things, I'd like to put my SVN version, date, user name, and maybe some other stuff into it in a way that can be read without a custom program. This needs to be done as part of the ant build (without requiring a custom java program).
For example, one approach would be "strings | grep <special-string>" if I could put something, somewhere in the file that had this as 8-bit character encoding.
For jars, making the jar executable and having the main print it out works, but I don't think that's do-able for ears and wars, and it would be desirable to have a consistent approach.
Anyone already doing this?
Ideas?

For example, I don't think you can specify a mainline in the manifest of an ear or war.
They have pretty strictly defined formats, and I don't want to risk violating a standard by tinkering outside the standard.Possible, but you can always run it as java -cp myWar.war my.utility.Version.
There may be another possibility, but I'm unable to find any reference though:
In my early Java days, I used to work on a system where there was a Unix utility (called something like +"ident"+) that was able to extract version and description info stuffed in a .so file (under which "standard" or proprietary format was the info stored, I don't know).
I used to see it work on individual Java .class files too (from memory we had to put a String constant name "VERSION" in the class) and maybe jar files (I'm unsure).
One of my co-workers at that time had described that as a standard tool, but "ident" turns up nothing of that kind on Google... And I've never since encountered any description of the "VERSION" constant naming convention...
I was young and naive, I hope I were not bluffed by some alias in a custom setup... :o(

OK a bit more reserah turned up [that man page|http://man-wiki.net/index.php/1:ident]. Apparently ident is part of RCS (installed along with CVS), and works by grepping the target file for patterns such as "$keyword: text $" (which is RCS/CVS keyword substitution pattern). Now that it mentions it, I remeber that that's what we put into our VERSION constant's value ("$version : ...$", or something of that kind).
So:
1) it's not so standard after all, you have to install the rcs package on the target host (regardless of whether you use RCS for configuration management, which would probably be a bad idea nowadays)
2) you have to put such formatted strings somewhere in your code or configuration files (easy with Ant, if not genuinely through Subversion)
3) To have it work on jar, war, ear, files, you have to make sure that the file is not compressed (otherwise the pattern might not appear in clear). I don't know whether that's easy to configure using Ant's jar, war, ear tasks.
A bit of a hassle compared to stuffing your own utility class and using java -cp...

Problem parsing XML with schema when extracted from a jar file

I am having a problem parsing XML with a schema, both of which are extracted from a jar file. I am using using ZipFile to get InputStream objects for the appropriate ZipEntry objects in the jar file. My XML is encrypted so I decrypt it to a temporary file. I am then attempting to parse the temporary file with the schema using DocumentBuilder.parse.
I get the following exception:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element '<root element name>'
This was all working OK before I jarred everything (i.e. when I was using standalone files, rather than InputStreams retrieved from a jar).
I have output the retrieved XML to a file and compared it with my original source and they are identical.
I am baffled because the nature of the exception suggests that the schema has been read and parsed correctly but the XML file is not parsing against the schema.
Any suggestions?
The code is as follows:
public void open(File input) throws IOException, CSLXMLException {
    InputStream schema = ZipFileHandler.getResourceAsStream("<jar file name>", "<schema resource name>");
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = null;
    try {
      factory.setNamespaceAware(true);
      factory.setValidating(true);
      factory.setAttribute(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
      factory.setAttribute(JAXP_SCHEMA_SOURCE, schema);
      builder = factory.newDocumentBuilder();
      builder.setErrorHandler(new CSLXMLParseHandler());
    } catch (Exception builderException) {
      throw new CSLXMLException("Error setting up SAX: " + builderException.toString());
    Document document = null;
    try {
      document = builder.parse(input);
    } catch (SAXException parseException) {
      throw new CSLXMLException(parseException.toString());
    }

I was originally using getSystemResource, which worked fine until I jarred the application. The problem appears to be that resources returned from a jar file cannot be used in the same way as resources returned directly from the file system. You have to use the ZipFile class (or its JarFile subclass) to locate the ZipEntry in the jar file and then use ZipFile.getInputStream(ZipEntry) to convert this to an InputStream. I have seen example code where an InputStream is used for the JAXP_SCHEMA_SOURCE attribute but, for some reason, this did not work with the InputStream returned by ZipFile.getInputStream. Like you, I have also seen examples that use a URL but they appear to be URL's that point to a file not URL's that point to an entry in a jar file.
Maybe there is another way around this but writing to a file works and I set use File.deleteOnExit() to ensure things are tidied afterwards.

In PI 7.1 - Java UDF's Compiled Class files - Jar File location

Hi All,
In PI 7.1 Does anybody know where the compiled Java UDF's (which are used in Graphical mapping) class files stored in jar are located in integration server? I want to use this jar file in my XSLT mapping.

Hi,
I guess it would be under
\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\temp\classpath_resolver
or
\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\.\temp\classpath_resolver
Where SID is your XI instance name.
Thanks,

Calling class or jar file location

If you don't know what called your program, then there is no way.

Common jar files location

We have several "common" jar files that will be used across several of our existing
applications. We are currently trying to figure out the 'best' location for these
files. There is one school which feels that /opt/bea/wlserverX.x/ext is the proper
location for these files and others say /opt/bea/wlserverX.x/lib, yet a third
opinion is to put it at the same level as the aformentioned directories.
Has anyone run into this in the past and what was your solution?
any help would be greatly appreciated!!
Sebastian

Just put it in a commonly shared path of the classpath. For example the /lib folder of the application server in question. You only need admin rights on the appserver in question to be able to place the JARs in there.

im have having a problem on extracting mysql's

How to structure a JSF application (EAR/WAR/JAR)

Hi All,
How do you recommend I should structure a JSF application in terms of EARs, WARs and JARs?
Let me set the context for you: I have a fairly large project which consists of a number of sub components. Each of these sub components are JSF applications in the sense that they have JSF pages connected to each other. So, for instance, I have a company management sub component and a product management subcomponent. Most of these sub components share some Java libraries and/or entities.
Because of this I decided to have each sub component contained in its own WAR, with no universal libraries in its lib folder, and to then add these WARs to an EAR with all the library JARs in the EAR's lib folder, as so:
EAR
   |_ component1.WAR
   |_ component2.WAR
   |_ lib
         |_ sharedlib1.JAR
         |_ sharedlib2.JARUnfortunately I'm having more problems than I hoped I would with JSF with this setup. An alternative I have is to create one gigantic WAR which contains all the library archives and then to only deploy this WAR. Although this would probably work, it destroys the nice seperation I had between sub components, where I could for instance just remove the one WAR from the EAR if it was giving problems. That structure would look something like this:
WAR
   |_ <WebContent>
   |_ WEB-INF
             |_ classes
                       |_ <JSF classes>
             |_ lib
                    |_ sharedlib1.JAR
                    |_ sharedlib2.JARFinally, I have a third option where I add all the libraries required by a WAR to its lib folder and I have no shared libraries in the EAR's lib folder. The disadvantages are of course that the EAR will be huge as JARs get duplicated unnecessarily, and I'm not sure that this won't cause conflicts. The structure would look like this:
EAR
   |_ component1.WAR
                    |_ WEB-INF
                              |_ lib
                                    |_ sharedlib1.JAR
                                    |_ sharedlib2.JAR
   |_ component2.WAR
                    |_ WEB-INF
                              |_ lib
                                    |_ sharedlib1.JAR
                                    |_ sharedlib2.JARI believe the first way to be the best, but I'm struggling getting JSF to work like I expect (see [http://forum.java.sun.com/thread.jspa?threadID=5288069|http://forum.java.sun.com/thread.jspa?threadID=5288069] ). What are your suggestions?
Thank you,
Ristretto

Dear hiwa,
thank you very much for your response. I have had a look into the book and found out that it provides indeed half of the solution i need. Now I can generate a JSF response to my non-JSF request which has been issued by the main application.
Unfortunately this is only the first half of the solution, because the JSF framework of the child application will still render URIs into HTML-forms (e.g. for the <f:view>) that point to the faces servlet and not to the non-JSF servlet of the main application.
I'll try to solve this problem by providing my own ViewHandler that provides other URIs. But I still don't know how to encode the view ID into the generated HTML-form as a hidden field.
After all, I am really surprised at how difficult it is to integrate the JSF framework into a non-JSF application. I don't think this is a very uncommon scenario. In my case, we integrate into an existing large application of our customer in order to extend his application with our product. I would expect this to work out of the box with JSF (sigh).
I will post my progress in this matter if I found some interesting solution.
Bye, Marcus
