Download java (Java SE for Embedded 6 Update 21 (Build 9) ARMv7 Linux - Headful, EABI, Hard Float (VFP), Little-Endian) from here: https://cds.sun.com/is-bin/INTERSHOP...-CDS_Developer

Extract ejre1.6.0_21 from the archive to MyDocs in N900
Move ejre1.6.0_21 to /opt (I was using MC)
Run in terminal as root:
ln -s /opt/ejre1.6.0_21/bin/* /usr/bin/
chmod 777 /usr/bin/java
ln –s /opt/ejre1.6.0_21/lib/arm/libnpjp2.so /usr/lib/browser/plugins/libnpjp2.so
ln –s /opt/ejre1.6.0_21/lib/arm/libnpjp2.so /home/user/.mozilla/plugins/libnpjp2.so
Then in microB and Firefox type about:config in address
Search for java
Change java.java_plugin_library_name to libnpjp2.so
I don’t know if changing in about:config is needed because I did this at the beginning.
After that chromium was running java without any changes.
