How to Fix Eclipse BIRT Font Problems

I faced two irritating font problems while using BIRT. They are:

1) Turkish character problems while exporting report as PDF. Some Turkish characters were not displaying well while using BIRT PDF engine(iText). Use Ariel font, it is an easy fix I know but it just works, and saves hours, that is all.

2) The other problem was using same width the fonts. You can find the full list of same width fonts here. I used Courier New, it worked.

Have fun ;)

How to Change Glassfish Ports

I wanted to change default http port other than 8080. (I am using tomcat with the same port)

To do so you should go to glassfish home directory

cd glassfish (this will be yours)


After than you should change the port to an other value. Write the command below

vim domains/domain1/config/domain.xml

Find 8080, and change to the desired port. Save and exit then.

to start web server write the command below

bin/./asadmin start-domain domain1

To stop you should write

bin/./asadmin stop-domain domain1

How to Solve Tomcat OutofMemory Error on Linux

Go to your tomcat home directory. Edit catalina.sh file using the command below.

vim bin/catalina.sh

Then find the line

CATALINA_OPTS="$CATALINA_OPTS $JPDA_OPTS"

And edit it like below

For mine memory is assigned to 1200Mb.(You can change the value according to your system configurations) I think it will be fine. Goog luck.
