You can use
This command with print all Threads in application. Make request and if you see that tomcat is not returning make a couple Thread Dumps. Then search for your application package name eq( if you see the same method in a couple of Thread dumps it maybe your slow part.

I am try to log java.lang.Error, and for some reasons it is not logged using struts. I have situation where compiled files are not in right version and e.g class is using static filed from other class which is not synchnoized (excepted expetion: java.lang.Error: Unresolved compilation problem: )
Using simple servlets such exception will be in tomcat logs defined in $TOMCAT_HOME/conf/

So maybe struts handles such exceptions and some configuration is required ?

I have created database once againe and now it is working. Previously i have done manually some inserts to database, it think that there was problem but why could anyone explain.

I can't save date to database using hibernate. First i thought that it was sequence problem that can't get next value but in error message there is next sequence value.
What other thing can cause this problem.

i want to compare p2p(JXTA) vs client\server find advantagers ,disadvantage
and base on it write application in both architectures
the only advantage of using p2p which is my mind is computing speed

for example:user have 2 linear equations
client\server:client send request to server, server may have many other request to solve others linear equations ,one PC solve it
p2p: client send request to peer group(10 PC) ,peer group may have many request but there is 10 PC
(PC server = 1 PC p2p)
in p2p it will take less time

I need more examplers or maby complex one
thanks in advance

whata about add styles to AttributeSet i do somthin like this
Whene i click one of JToggleButons i add to string names of styles which
i deklar in addStylesToDocument method


Then i split this string to tables

String t[] = text.split("#");
String s[] = still.split("#");

for fist time i append to doc2

for to rest:
first i check which styles are to start style the differen beetwen
s.lenght - t.lenght give to where is start style

and append to doc like before

But the problem is tha this still String grow all the time so it the size of this will grow too i try to cut this string but the result was always bad

Maby there is better way to do this

but it loses styles
for exmaple i have bold after i insert icone it's change to regural

i have one more question it is possible to add Style to AttributeSet
becouse i need to send AttributeSet in byte array or string over network i
i try somthing like that but the size of byte array was to big from 13KB-300KB(if was a lot of styles in text)

My second option is to use style which are in addStylesToDocument() method
I can recognize style from string for example
i send String d = bold#italic#underline over network reciver it
and split it to table String [] dd = d.split("#") but whene i insert text

text will be one only bold or italic or underline it won't be italic and bold how to solve it
