Really? My java compiler does not seem to have read that article:
C:\Users\Richard\Documents\eclipse>javac BaseTest.java
BaseTest.java:16: variable parent might not have been initialized
if (aParent == null || parent == null) {
^
1 error

yeah - and then I realized how time flew by. I updated my runtime from V1.0 to V6 and got aware of the eclipse project...

No it doesn't.
It provides a default initialization for class member variables.
That is not the case for local variables. The compiler is responsible for flagging uninitialized locals as errors.

Strang,e it works fine for me; perhaps there is something else that you have not explained.

The message is reasonably clear; the HTTP server encountered an error which is recorded in the server logs.

I have a reporting application pulls in data via a JDBC connection and fills my report. It can use any standard JDBC driver that supports Prepared Statements. I now have the need to query XML files directly. Does anyone have any suggestions on a JDBC driver that will read an XML File? What I am looking for is an XML equivalent to CSVJDBC.
So far I have found two options that don't fit my situation very well.
StelsXML - Looks promising but this project currently has no budget.
Ashpool - Open source license. Looks abandon and still has major issues.

There are of course ways to extract information from XML data which have nothing to do with JDBC.
|

Yes I could extract the XML data to a database and then query it from there. I am trying to avoid this because it will require changes to the process that I do not control. The goal is the load the XML file like a table the same way CSVJDBC lets you load a CSV file like a table.

Could.
That however has nothing do to with what I said however.

I am going to presume at this point that you know nothing about the available APIs suited to accessing XML. Following is some background.
http://en.wikipedia.org/wiki/Document_Object_Model[^]
You should then google for resources on using XML in java.

Did you read his question?
He has an existing reporting tool that uses JDBC. He would like to use that reporting tool to access data in XML format.
His question is: is there any JDBC driver that will allow him to use the reporting tool directly on the XML data? Failing that, he could extract the XML into a database and then run the reporting tool over that, but he would rather not.
He is not asking about how to manipulate XML data. He is asking how to read XML through JDBC because that is the constraint he has in place with his reporting tool.

Now that it was pointed out that that I misread your question...
What is the complexity level of the report -> xml interface?
If it isn't too significant then one option would be to write your own JDBC driver. Put only the functionality you need into it. Something like a select with some simple where clauses isn't that difficult to convert into a xpath with the result set spanning the result of that.

I was hopeful that I could avoid writing something custom/new, but it sounds like that is the case. I could rewrite the reader interface for CSVJDBC.

Not a bad idea actually. That gives some trivial functionality for SQL that you then would not need to create yourself.
|

As another thought...
You mentioned loading to a database would be a problem. Why specifically?
As one possibility on that route, use the embedded version of Derby. That wouldn't require external resources and it already has the JDBC driver. So the only problem is the load itself.

i have this in my code:
properties props = new properties();
props.put("mail.transport.protocol", "smtps");
How do i replace those "properties.put" without having to use the properties ?
|
|
|
|
|
cool - it took just 2 weeks to figure out properties - fantastic!
You can write your own properties-file. It is a basic ASCII text file.
Or you save your data on an object. This requires programming.

yes i managed to figure out. i am teaching myself programming. Yes i manage to learn how to write a properties file alrdy..

What does this sentence mean? Are you saying that you want to write into your properties file without using the properties class?

oh the "prooperties.put" refers to writing to the properties file without having to key it in the properites file?

 The key is "mail.transport.protocol" and the value is "smtp".

Still does not make sense. Try a full explanation of exactly what it is you are trying to achieve.
