I am trying to evaluate what it would take to move an existing app from
WebLogic 8.1 to JBoss.
I am trying to get our app to initialize, and it's failing with FileNotFound
exceptions when trying to read property files stored in the EAR.
I've distilled things down to a very simple example to illustrate the problem.
I started with a very simple EAR that implemented a stateless session bean. My
EJB deploys, and I wrote a simple client app that sucessfully calls it. So all
of the deployment descriptors and InitialContext stuff works. I actually used
the MyEclipse plugin to create this enterprise project and deploy this to both
JBoss and WL.
Now, I need the path to a properties file (because as I scale this up, I need
that file name to initialize a Quartz StdSchedulerFactory). I took code from
our WebLogic deployed EJB and tried it in JBoss, but I get the FileNotFound
exceptions I described above.
Thing is, they go away if I deploy my EAR as an exploded EAR. This won't fly
for real, I want to deploy packaged.
Anyways - here what I get:
For an EAR packaged like so:
C:\jboss-4.0.2\server\default\deploy>jar xvf AdviceEAR.ear
extracted: advice.jar
extracted: APP-INF/classes/dao.properties
extracted: META-INF/MANIFEST.MF
extracted: META-INF/application.xml
This code works if deployed as an exploded EAR:
| public String getAdvice() {
| System.out.println("in getAdvice");
|
| InputStream daoProperties =
getClass().getClassLoader().getResourceAsStream("APP-INF/classes/dao.properties");
| Properties properties = new Properties();
| try {
| properties.load(daoProperties);
| if (properties != null) {
| for (Iterator it = properties.entrySet().iterator();
it.hasNext();) {
| Map.Entry entry = (Map.Entry) it.next();
| String value = null;
| String key = null;
| try {
| key = (String) entry.getKey();
| value = (String) entry.getValue();
| } catch (Throwable e) {
| System.out.println("Invalid dao
property for key [" + key + ", " + entry.getValue() + "] " + e);
| }
|
| System.out.println("Key: " + key + " Value: "
+value);
| }
| }
|
| } catch (Throwable e) {
| System.out.println("Failed to load dao properties file");
| }
|
| URL daoPropsURL =
getClass().getClassLoader().getResource("APP-INF/classes/dao.properties");
|
| if (daoPropsURL != null) {
| String daoPropsPath = daoPropsURL.getPath();
|
| if (daoPropsPath != null) {
| System.out.println("daoPropsPath is " + daoPropsPath);
| }
| else {
| System.out.println("daoPropsPath is null!");
| }
|
| String daoPropsFile = daoPropsURL.getFile();
|
| if (daoPropsFile != null) {
| System.out.println("daoPropsFile is " + daoPropsFile);
| }
| else {
| System.out.println("daoPropsFile is null!");
| }
|
| }
| else {
| System.out.println("daoPropsURL is null");
| }
|
|
| Properties urlProperties = new Properties();
| try {
| FileInputStream is = new FileInputStream(daoPropsURL.getFile());
| urlProperties.load(is);
| } catch (Throwable e) {
| System.out.println("Failed to load dao properties file: " +
e.getMessage());
| }
|
| if (urlProperties != null) {
| for (Iterator it = urlProperties.entrySet().iterator();
it.hasNext();) {
| Map.Entry entry = (Map.Entry) it.next();
| String value = null;
| String key = null;
| try {
| key = (String) entry.getKey();
| value = (String) entry.getValue();
| } catch (Throwable e) {
| System.out.println("Invalid dao property for
key [" + key + ", " + entry.getValue() + "] " + e);
| }
|
| System.out.println("Key: " + key + " Value: " +value);
| }
|
| }
| int random = (int) (Math.random() * adviceStrings.length);
| return adviceStrings[random];
| }
|
The result:
| 16:41:55,878 INFO [STDOUT] in getAdvice
| 16:41:55,898 INFO [STDOUT] Key: property4 Value: D
| 16:41:55,898 INFO [STDOUT] Key: property3 Value: C

But deployed as a packaged app, I get:

Why? It works fine both ways in WebLogic. That exclamation point in the path
and file name when calling getResource() obviously look suspicious. What am I
doing wrong?
