Installation Problems
Q: Under Mac OSX Lion (10.7.x): On JavaView launch several error messages
are printed in the console of the type
java[31185] <Error>: CGContextGetCTM: invalid context 0x0
java[31185] <Error>: CGContextSetBaseCTM: invalid context 0x0
java[31185] <Error>: CGContextGetCTM: invalid context 0x0
java[31185] <Error>: CGContextSetBaseCTM: invalid context 0x0
A: This bug seems to appear on OSX Lion and newer, but apparently it
does not have any serious impact, so you may ignore it.
Q: I have installed Eclipse and Java but every time I try to run Eclipse
it says "A Java Runtime Environment (JRE) or Java Development Kit
(JDK) must be available in order to run eclipse. No Java virtual machine
was found after searching the following locations: C:\eclipse\jre\bin\javaw.exe. javaw.exe in your current path"
A: Usually the Java installation automatically sets the Java installation
path in a global environment variable. What is most likely is that you
have downloaded Eclipse and Java for different architectures, e.g. Eclipse
for 64bit Windows and Java for 32bit Windows. Under Windows 7, 64bit
software is typically installed under Program Files whereas 32bit software
is installed under Program Files (x86). Make sure that your versions are
for the same architecture, i.e. if Java 64bit is installed then use Eclipse
64bit and vice versa. If Java 32bit is installed then use Eclipse 32bit and
vice versa.
Note that you can have both versions installed at the same time, but the
default Java runtime environment is probably set to only one of them.
