Hi all !
Hehe, I finded solution, that is simple.
- The first : modify file run.bat in JBOSS_HOME\bin.
Remove "rem" in line :
"rem set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m"
-> "set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m".
Because default size of heap memory in JBoss server is 64MB therefore you can increase size by modify digit 128 and 512 depending on size of RAM on your computer.
128 - that is total memory reserved for JVM.
512 - that is max memory reserved for JVM.
- The second : Run file run.bat in folder JBOSS_HOME\bin in order to start JBoss server, not start JBoss server in JBoss Eclipse (remember).
In order to check result modified, you can access web-console screen of JBoss at address : http://localhost:8081/web-console/.
Look and feel result.
Thanks all.
