Having problem with compiling XMLGreeting.java

Dear whom it may concern,

I have following set up…
1)Tamino Database called “myDB” is created and running
2)jdom.jar, log4j.jar, TaminoAPI4J.jar, TaminoJCA.jar, JavaTaminoAPIExamples.jar, xercesImpl.jar, xmlParserAPIs.jar, are included

I have tried to compile source code by using command:
javac XMLGreeting.java,
Unfortunately I got the following message warning:

Note: ProcessXMLGreeting.java uses or overrides a deprecated API.

Note: Recompile with -deprecation for details

However I got XMLGreeting.class so I have tried to execute this file by executing command:

java XMLGreeting

Unfortunately, I got the following error message exception:

Exception in thread “main” java.lang.NoClassDefFoundError: XMLGreeting (wrong name: com/softwareag/tamino/db/api/examples/greeting/XMLGreeting)

at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:322)

Then I commented out the “package” line in the sample code and recompiled, but still got the same error messages…
Could you help me what I should do?
Thank you very much in advance,

/****Sample Code/

You raise three issues in your post.

First, the compiler messages about deprecation. These can be ignored. The most recent API has some changes to the way exceptions are handled. The examples use an older api which is now deprecated. You can read about the deprecated methods in the API documentation, but you don’t need to make any changes for the example code to work.

Next the package issue. You can either put the code into a directory structure that matches the package structure, or (as you have already done) comment out the package statement.

Finally, you still get an error when you run your non-packaged version of the example. I can’t reproduce that problem so could you please delete the example class file and recompile the source to rebuild the class. Then run the example and post the error to this forum.

Many thanks.

Thanks for answering my questions…

yeah… when I commented out the “package line” :
//package com.softwareag.tamino.db.api.examples.greeting;

I was able to compile XMLGreeting.java with following message…
Note: ProcessXMLGreeting.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details

then, when I ran the XMLGreeting.class, I got the different error message than before…
C:>java XMLGreeting
Exception in thread “main” java.lang.NoClassDefFoundError: com/softwareag/tamino/db/api/accessor/TQueryException

The code is the same as above. Could you help me figuring out how to fix this problem?

Thank you very much!

Hello Myong,

this looks like a CLASSPATH problem.

Generally you will need at least the TaminoAPI4J.jar, jdom.jar and log4j.jar files in your classpath to run a Tamino API for Java application.
(A parser is also required, but there is one included in JRE 1.4.1, so you probably do not need the Xerces Jar files in your classpath.)

You can find these Jar files in the SDK\TaminoAPI4J\lib directory of your Tamino installation.

I hope that helps,
