java.lang.NoClassDefFoundError: org/w3c/tidy/Tidy in Linux box

Hi

I'm using BIRT 2.5.2 and created the report using eclipse.
When I deploy and run in Windows m/c , it is working fine.

But the same code was deployed in Linux m/c.
When I run the report I get the error

In windows it is working well.

Hi 
 
org/w3c/tidy/Tidy is available in Tiny.jar. I exclusively set the classpath for Tiny.jar 
 
/local/apps/gpb/domains/TMAdmin3/deployed_apps/tmadmin-SNAPSHOT/WEB-INF/platform/configuration/org.eclipse.osgi/bundles/60/1/.cp/lib/Tidy.jar 
 
It didn't work. 
 
Then I copied the Tiny.jar and put it in some other directory and set the classpath 
 
/local/apps/3rdparty/birt/Tidy.jar 
 
It didn't work. 
 
Why even after setting the classpath exclusively for Tiny.jar, the exception is thrown ???

As I have alredy mentioned, it works well in Windows Weblogic. 
Fails in Linux Weblogic ? I just copied and pasted the WEB-INF directory and subfolders from windows to Linux. 
 
Any reason why it behaves like this ???

JasonW

The tidy jar is already available as part of the report engine plugins.
Specifically in org.eclipse.birt.report.engine. If you add it again it will most likely fail. In your setup to have all the jars from the ReportEngine/lib in your classpath? Do you have all the plugins in your birt home directory?

Jason

sgeovar

All the ReportEngine/lib are in classpath.(WEB-INF/lib) directory.

Still getting error.

Should I change anything in WEB-INF/platforms/plugins/configuration/config.ini ??

config.ini has following entries

#Product Runtime Configuration File
eclipse.product=org.eclipse.birt.report.engine.ReportEngineSDK
osgi.bundles=org.eclipse.equinox.common@2:start, org.eclipse.update.configurator@3:start, org.eclipse.birt.core@start
osgi.framework.extensions=org.eclipse.birt.api
osgi.bundles.defaultStartLevel=4

How are you setting your BIRT home?

Jason

sgeovar

I didn't set the BIRT HOME because in Windows it worked well without setting BIRT HOME.

Code follows

EngineConfig config = new EngineConfig();
if (configProps != null) {
String logLevel = configProps.getProperty("logLevel");
Level level = Level.OFF;
if ("SEVERE".equalsIgnoreCase(logLevel)) {
level = Level.SEVERE;
} else if ("WARNING".equalsIgnoreCase(logLevel)) {
level = Level.WARNING;
} else if ("INFO".equalsIgnoreCase(logLevel)) {
level = Level.INFO;
} else if ("CONFIG".equalsIgnoreCase(logLevel)) {
level = Level.CONFIG;
} else if ("FINE".equalsIgnoreCase(logLevel)) {
level = Level.FINE;
} else if ("FINER".equalsIgnoreCase(logLevel)) {
level = Level.FINER;
} else if ("FINEST".equalsIgnoreCase(logLevel)) {
level = Level.FINEST;
} else if ("OFF".equalsIgnoreCase(logLevel)) {
level = Level.OFF;
}

config.setLogConfig(configProps.getProperty("logDirectory"),
level);
}

config.setEngineHome("");
IPlatformContext context = new PlatformServletContext(sc);
config.setPlatformContext(context);

try {
Platform.startup(config);
} catch (BirtException e) {
e.printStackTrace();
}

JasonW

did you write your own servlet?

Jason

sgeovar

Yes, I write my own servlet.
It calls the BirtEngine

BirtEngine Code

if (birtEngine == null) {
EngineConfig config = new EngineConfig();
if (configProps != null) {
String logLevel = configProps.getProperty("logLevel");
Level level = Level.OFF;
if ("SEVERE".equalsIgnoreCase(logLevel)) {
level = Level.SEVERE;
} else if ("WARNING".equalsIgnoreCase(logLevel)) {
level = Level.WARNING;
} else if ("INFO".equalsIgnoreCase(logLevel)) {
level = Level.INFO;
} else if ("CONFIG".equalsIgnoreCase(logLevel)) {
level = Level.CONFIG;
} else if ("FINE".equalsIgnoreCase(logLevel)) {
level = Level.FINE;
} else if ("FINER".equalsIgnoreCase(logLevel)) {
level = Level.FINER;
} else if ("FINEST".equalsIgnoreCase(logLevel)) {
level = Level.FINEST;
} else if ("OFF".equalsIgnoreCase(logLevel)) {
level = Level.OFF;
}

config.setLogConfig(configProps.getProperty("logDirectory"),
level);
}

config.setEngineHome("");
IPlatformContext context = new PlatformServletContext(sc);
config.setPlatformContext(context);

try {
Platform.startup(config);
} catch (BirtException e) {
e.printStackTrace();
}

IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);

birtEngine = factory.createReportEngine(config);

}
return birtEngine;

JasonW

I understand now. the line setEngineHome("") sets the birt home variable. I noticed in your post you had WEB-INF/platforms/plugins/configuration/ as a directory structure. Is it in the platforms directory or platform directory? You use a PlatformServletContext which requires the plugins to be in the platform/plugins directory. Also verify that when you start your servlet for the first time in your environment that the configuration directory only contains a config.ini. Additional files will be created in this directory which is ok, just make sure it only contains a config.ini the first time you run it.

It is in the platform/plugins directory. Sorry for the typo.

I removed all the files except config.ini from /WEB-INF/platform/configuration directory and stopped the weblogic server and started again.

I get the same error again.

The directory /WEB-INF/platform/configuration has only config.ini file after running the engine. No additional files are created.

is any refresh required ??

JasonW

Is there write permission on the configuration directory?

Jason

sgeovar

Hi Jason

configuration dir. doesn't have the write permission.
I changed it and the new files and directories are created.
Report is working well and I got the report.
Thank you very much for your help.

This is a web report (PDF) . When I hit the URL from the browser I get the dialog window first.
It asks me to save or cancel. I close the dialog window and again fire the URL. I get the report on the browser.
All the subsequent requests are working well.

But the when hit the servlet first time , I get the dialog box .

How to avoid this ? I want my report directly display on the brower in the first attempt itself.

Once again Thank you very much for you to fix the NoClassDefinitionFound error.

Thanks

sgeovar

Hi

I forget to mention one more thing.
This dialog box appears in Weblogic only.
If I run the same application in Tomcat, I don't get this error.

Thanks

JasonW

I believe that is a browser setting for the mime type.
