Re: how to lock the access to an array till a method is finished ...
Yes Adrian,
if I synch ON THE OBJECT and only the access code for that object on both
sides, it works...
Many thanks.

Re: how to lock the access to an array till a method is finished ...
I have already do this but does not help. The synch in this case does not help, as it LOCKS the object that calls the method and NOT THE the array that is used by the method and also by the jsp page. (my use of 'volatile' also does not help). Ionel. > Syncronize the code/method that populates the array as well as the > code/methods that access it.

how to lock the access to an array till a method is finished...
Hi, I have the following situation: In a bean, I have a method that populates an array with a large, very large amount of data (required for some operations). >From my jsp page I do not want to allow any web clients to see the length of this array, till the process of population is finishedI mean that otherwise one can see intermediary results and I want to avoid this. (I have tried to mark volatile the array but this helps me only to keep the correct value in all the threads, does not lock me also the object). Do I have to use a complicated wait/notify mechanism to achive this or how can I do ? Many thanks, Ionel C. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Thread dumps with weblogic
Hi, IF you have done a 'kill -3 PID' than the core dump of the memory will be in a file called 'core' that is located in the directory from where the killed process (java) was started. So if your process was started (just an example) from /usr/bin/... and you are trying to kill it from /home/myaccount and you don't have the write permission to /usr/bin, IMHO the core will not be created even if the process will be killed, so you have (the right to kill it). (at least works in this way on redhat linux).

Re: obtaining date and time in suitable format for MySQL
No way Hugo !!!
You should use the java.util.GregorianCalendar class , as follows:
Calendar calendar = new GregorianCalendar();
Date trialTime = new Date();
calendar.setTime(trialTime);
System.out.println("YEAR: "+calendar.get(Calendar.YEAR));
here your code...
For any reference, please consult
http://java.sun.com/j2se/1.3/docs/api/java/util/GregorianCalendar.html
and you will find all the methods() that you need.

TEXTAREA behavior in IE and Netscape
Hi, Here is my problem: In a textarea a user must be able to inputs (to paste) a text document than sends the form (which contains some other Input elements) to the server using post. In Netscape the textarea limits myself to introduce more than approx. 24376 chars (I can't TYPE more chars). But the problem is in IE: I introduce less than approx 2000 chars, works ok but if I try to introduce let's say the number of chars allowed in netscape the IE is not able to sent the info to the server, sometimes gives me a timeout operation, otherwise "...cannot open site, terminated" and otherwise simply does nothing, just tries to send ...than... back to my page. The problem is that I HAVE TO use IE asap, so how can I solve the problem ? Do you know if it is related to HTTP or simply a different convention in IE and netscape, as seems for me.

Re: How do I Change the Sort Order?
Hi,
I am not absolutely sure but I think that in the class which inherits this class
you should
explicitly write "<" or " >" in the overriden method compareElementAt(...)
ex.
public int compareElementsAt(int beginLoc, int endLoc) {
if(beginLoc>endLoc)
return -1;
else return 1;
}
or for reverse order:
public int compareElementsAt(int beginLoc, int endLoc) {
if(beginLoc How do I change the sort order in this code?

Re: minutes ,seconds????
Hi, If you refer to the methods of the java.util.Date class, they are deprecated (considerate old), since it is encouraged the use of the java.util.Calendar class or better the java.util.GregorianCalendar. If you refer to the methods of java.sql.Date class, they are deprecated because an SQL JDBC Date object does not contain time information, only date. For the time information you must use the java.sql.Timestamp class.

JSP & DB2
Hi, If someone uses IBM DB2 as his DBMS for JSP here is a question: I have two databases, each with a few tables. Somewhere in a bean I write a query which must use a table from DB1 and a table from DB2 is a select statement. Does anyone know how to configure DB2 (grant statements I suppose) in order to succeed... I mean one of the DB to see also the tables from the other DB. I have done the same thing in Oracle by allowing rights on a scheme but I don't know how can be done in DB2. Please give me an example. Thanks, Ionel Condor. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Can I read a text file thru a bean
You may use a format as follows:
file.ini
---
driver=namedriver
db=namedb
.
this is the classical format of a properties file.
Than you just open a stream to that file and use the load function of a java.util.
Propeties object to load the whole file.
than do something like:
name=prop.getProperty("db");
driver=prop.getProperty("driver");
Example:
java.io.FileInputStream is = null;
java.util.Properties p = new java.util.Properties();
String propertiesFilename = "settings.ini";
try {
is = new java.io.FileInputStream(propertiesFilename);
p.clear(); // not realy necessary
p.load(is);
//System.out.println("pr:" + Prop.properties.toString());
} catch (java.io.IOException ioex) {
System.out.println("Can't read the settings file");
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (is != null) {
try {
is.close();
} catch (java.io.IOException ioex1) {
ioex1.printStackTrace();
}
is = null;
}
}
than
even you use an: Enumeration e = p.keys();
or simply get a value of a property as I have shown you above.

Re: This is very ***important*** for me ..please help.
Just a suplementary note, not a solution to your problem:
You forgot to close the connection; take care that this is a serious problem
for a web site using jdbc as after a time all the objects will be alocated by the
DBMS and you will get an error.
Always close the connection after a comit or rollback... (and other jdbc objects)
or better use a connection pool.

JRun233 vs JRun3
Hi, Does anyone know what version of Servlet's API does know JRun233 ? Shall I upgrade to version 3 ? Has version 3 significant improvements?

Re: Prob of Servlet objects in JSP functions
Hi, I am using Visual Age for Java integrated with Tomcat and the debugging process works very vell. I think that any IDE support jsp/servlets.

sending via POST
Hi, I have a form which sends some data via POST. I want to know a modality to see what is realy sent to the server without changing the post to get. I have no access to the server all the time, so I can't assume that I read these values on server... I need a way to intercept the communication, something like C raw sokets I think... Do you know such a method or a utility program that does such a job of showing the query as it was send by a get method? (I don't need a sniffer application for reading pwd and so on).
