java.sql.SQLException: User not found: SA [SOLVED]

WARN [org.jboss.system.ServiceController] Problem starting service jboss:service=Hypersonic,database=localDB
java.sql.SQLException: User not found: SA

It's possible that your jboss deployment has gone a bit squiffy.. try deleting the following:
jboss/server/default/tmp
jboss/server/default/data
jboss/server/default/work

Exception creating identity: domainName

caused by: java.lang.RuntimeException: Exception creating identity: domainName

Solution

your computer can't find itself

go to:

etc/hosts
make sure the loopback address refers to the name of the box you are running on ie
127.0.0.1 documentationServerBox localhost.localdomain localhost

Tomcat prunsrv.c javajni.c [error] - Service Error

When tomcat generates something similar to the following log output chances are its missing the Windows C dll MSVCR71.dll - Tomcat needs this to initialise java when the service starts. Put a copy in your c:\windows\system32 directory or wherever you want as long as its in your system path

Copy a file in Java

public static void copyFile(String sourceFile, String filePath, String destinationFile) {

try {
FileInputStream streamSource = new FileInputStream(sourceFile);
FileOutputStream streamDest = new FileOutputStream(filePath + destinationFile);

byte[] buffer = new byte[1024];
int i = 0;
while ((i = streamSource.read(buffer)) != -1) {
streamDest.write(buffer, 0, i);
}
streamSource.close();
streamDest.close();

} catch (IOException e) {
// LOG.debug("file(input|output)stream error: " + e);
}

Simple Regex replace in java and Striptags

replacing two chars using an or (pipes)

String p = "text to search.. through with = and , and ^

regex

System.out.println("result: "+ p.replaceAll(",|=", "") );

if you want to strip all the tags out you can use:

System.out.println("p: "+ p.replaceAll("\\W", " ") );

note.. that will strip spaces too hence we are replacing with " "

to strip tags properly and remove what's between them use

System.out.println("p: "+ p.replaceAll("<[^>]+>", "") );
