Someone else set up my eclipse environment. I would like to know which of the many Oracle instances available it is pointing to and change the password it is using. Where can I find this in Eclipse? Can I point to two Oracle instances at the same time? How hard is it to switch back and forth?

I found an example at
http://weblogs.java.net/blog/dwalend/archive/2004/11/amazing_xlint.html
<javac compiler="${build.compiler}" srcdir="${source.delivery}" destdir="${build.delivery}" deprecation="yes" debug="yes">
<compilerarg value="-Xlint"/>
<classpath refid="classpath" />
</javac>

seems to have gotten past the compiler

Has Xlint quit working for newer java.

my java -version shows as "1.5.0_04"

I can use -deprecation by itself

I cannot complete my canned Ant build with out using the xlint:unchecked and it is not listed with javac -x

does not work

<javac compiler="${build.compiler}" srcdir="${source.delivery}" destdir="${build.delivery}" debug="on" >
<compilerarg value=" -Xlint:unchecked -Xlint eprecation" />
<classpath refid="classpath" />
</javac>

does not work

<javac compiler="${build.compiler}" srcdir="${source.delivery}" destdir="${build.delivery}" debug="on" >
<compilerarg value=" -Xlint:unchecked -Xlint eprecation" ></compilerarg>
<classpath refid="classpath" />
</javac>

and many other even sillier permutations. I have looked at the documentation and lots of web sites. What incredibly stupid thing am I doing incorrectly.

Coming from the IBM mainframe I got a lot out of Thinking in Java

I am trying to change existing code to JAVA 5 and getting part way there but some paths lead back to modules for which I have no source, only class files. For example com.efsol.util.AtributeContent

Any ideas on how to proceed?

I also broke the Friki Wiki
I wanted to save my data (new pages) on a share drive which is not a server so I entered its address. Start up shows.

But before the first page can be displayed a regular expression throws up.

description The server encountered an internal error () that prevented it from fulfilling this request.

The following looks a little funny because '\n' was used to break the line.

Poking around I am sure my address did it but I cannot figure out how to change the regular expression to allow the address or how to remove the address (short of reinstalling).

Regular Expression was in the original wiki.transform

Any help appreciated.

I also am looking for an explanation of the tilde (~) in above &~1 vs &1

still wandering

I am working through a tutorial http://javaboutique.internet.com/tutorials/Struts/jsp_page.html
and of course it does not work immediately so I am comparing the bits to struts-blank and struts-example as distributed. My error is:

org.apache.jasper.JasperException: Cannot retrieve definition for form bean null
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
etc

Here are my bits and pieces

SubmitForm.java

package playground;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.*;

public final class SubmitForm extends ActionForm {

============

struts-config.xml

<form-beans>
<form-bean name="submitForm"
type="playground.SubmitForm" />
</form-beans>

<global-forwards>
<forward name="submit"
path="/submit.do"/>
</global-forwards>

<action-mappings>
<action path="/submit"
type="playground.SubmitAction"
attribute="submitForm"
scope="request"
input="/submit.jsp"
validate="false">
<forward name="success" path="/submit.jsp"/>
<forward name="failure" path="/submit.jsp"/>
</action>
</action-mappings>

============
Submit.jsp

<html:form action="submit" >
Last Name: <html:text property="lastName"/><br>
Address: <html:textarea property="address"/><br>
Sex: <html:radio property="sex" value="M"/>Male
<html:radio property="sex" value="F"/>Female<br>
Married: <html:checkbox property="married"/><br>
Age: <html:select property="age">
<html ption value="a">0-19</html ption>
<html ption value="b">20-49</html ption>
<html ption value="c">50-</html ption>
</html:select><br>
<html:submit/>
</html:form>

I enter http://localhost/strutsApp/index.jsp

which does
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<logic:redirect forward="submit"/>

the URL changes to http://localhost/strutsApp/submit.do

I tried adding some of the parameters mentioned above to the form but they all produced new errors. For example when I added attribute there was a message about the tld. I have not found discussion of when it is name="myform" and when it is attribute="myform". Also find the changes from dots to slashes in URL/ URI / directory description mysterious.
Any wise words welcome.

Well so much for that theory. Found sourceDataLine.available() and displayed it as REMAINDER.
In PlayThread - cnt= 10000
remainer= 8192
In PlayThread - cnt= 10000
remainer= 6192
In PlayThread - cnt= 10000
remainer= 188
In PlayThread - cnt= 10000
remainer= 2176
In PlayThread - cnt= 8024
remainer= 168

The full buffer is not used every time and the remaining bytes vary without seeming logic.

I get the error on the last iteration of a loop such as follows

while((cnt = audioInputStream.read(
tempBuffer,0,tempBuffer.length)) != -1
&& stopPlayback == false){
System.out.println("In PlayThread - cnt= " +
cnt + "\n");

if(cnt > 0){
//Write data to the internal buffer of
// the data line where it will be
// delivered to the speaker.
sourceDataLine.write(tempBuffer, 0, cnt);
}//end if
}//end while

the display shows the first so many passes of the loop with cnt = 10000
When the last iteration is less than 10000 it is I A.S.S.U.M.E. not an "integral number"

Messy --- is there a cure.
