Hi, Luciano and Michael
thanks for your reply. Actually I want to get a text reply from a URL.
Finally I found I can directly put the query text in the URL and open an
connection with URL url = new URL(http://url/querytext), then use
bufferedreader to read it in.
But now I have a new problem. I used JSDK2.0 before. Today I installed
JSWDK1.0.1 which includes JSDK2.1 and JSP1.0. But when I start server, I got
following err:
stella@lewis:~/java/JSWDK/jswdk-1.0.1 > startserver
Using classpath:
./webserver.jar:./lib/jakarta.jar:./lib/servlet.jar:./lib/jsp.jar:./lib/jspengine.jar:./examples/WEB-INF/jsp/beans:./webpages/WEB-INF/jsp/beans:./webpages/WEB-INF/servlets:./lib/xml.jar:/lib/tools.jar
stella@lewis:~/java/JSWDK/jswdk-1.0.1 > JSWDK WebServer Version 1.0.1
Loaded configuration from:
file:/home/stella/java/JSWDK/jswdk-1.0.1/webserver.xml
Can not start endpoint on localhost/127.0.0.1:8080 due to exception
java.net.BindException: Address already in use
do u have any idear about this?
cheers
Stella
