Vijay:
"System.err.println()" only displays that message in the console
telling you how to run the java application. Usage statements are
common in Java console programs, since they tell you how to use a new
program and what arguments should be passed to it when you don't invoke
it correctly. It looks like you have the right *idea*, but you don't
put those directories into the System.err call (that would just print
them out on the console with the message) - you pass them on the command
line. In Eclipse, you can pass them by clicking Run >> Open Run Dialog,
making sure the ExampleApplication is selected as your main class, and
adding the three paths (the analysis engine descriptor, input directory,
and output directory) to the Program Arguments box in the Arguments
tab. Make sure to surround each argument/directory with double-quotes
if they have spaces in them (it doesn't appear so in your example code
here).
As for the error about missing ")", you've sort of butchered the
quotation marks in that System.err call. Eclipse should be syntax
highlighting that for you, so you should be able to work out when the
string is closed with the correct quotation mark and when it isn't. I
would just change it back to the way it was though and save yourself
some time.
These aren't really UIMA errors, though, but fundamental Java ones,
so I don't know if this is really the place to discuss them (Sun's Java
forums may be better suited to some of the general Java questions).
Walk through the code of the ExampleApplication starting from the main()
method. If there are things you don't understand or are giving you
errors when you run it, do a quick google search to see if other folks
have had the same problem. Make a decent effort to debug on your own,
and then come back if you're up against a wall.
Sidestepping to your question about regular expressions, their used
to match patterns in strings, and I'm sure you'll find them very useful
both inside and outside of UIMA. I find the website
http://www.regular-expressions.info/ very helpful when reading up on the
subject, but again, Google is your friend.

Hi adam,
at last i found the java class,so i just added that class to
my project wrote as a java
class,there i am getting an lke this
Usage: java com.ibm.uima.example.ExampleApplication <TAE descriptor or TEAR
file name> <input dir> <output dir>""
actually i have tried this when i am doing my first example i got the same
error .now i have given here like this
System.*err*.println("Usage: java com.ibm.uima.example.ExampleApplication "+
"<AnalysisEngine.xml> + <D:"\"eclipse\vijay\workspace\exampleApplication\input>
<D:"\"eclipse\vijay\workspace\exampleApplication\output>")
i am getting an error like this
"Syntax error, insert ")" to complete MethodInvocation".
i have tried not my best.
AND my aim also develop full fleged compnent to search for unstructured
data,my people want to use this as search tool in their project.this one is
ultimate goal.
i don't how far i am going to suceed in this but i want give my best with ur
support.......

Hi Adam Lally ,
as per ur code below i have tried
analysisEngine.setConfigParameterValue("StringsToAnnotate",
new String[] {"Michael","UIMA","Vijay",....}); but it is
giving anerror like analysisEngine cannot be resolved. i am attching the
class what i wrote.
Vijay,
The setConfigParameterValue call does not go in the annotator. It
goes in your main program. The idea is that the main program sets the
configuration parameter values before calling the annotator. It
wouldn't make any sense for the annotator code to set its own
configuration parameter values, then it might as well just hardcode
the values it was searching for!
Did you look at ExampleApplication.java yet? You asked how to write a
Main program, and you were on the right track with that. In
ExampleApplication.java's main method you have this line of code:
AnalysisEngine ae = UIMAFramework.produceAnalysisEngine(specifier);
And you would put after it:
ae.setConfigParameterValue("StringsToAnnotate", new String[]
{"Michael","UIMA","Vijay"});
Regards,
