Hello,
Not sure if it is the right mailling list but here we go anyway.
I am currently using the Entities.java class (well I am using the
StringEscapeUtils.java which uses that class). Works really good, saved me a
lot of time. My thanks to the people who wrote it.
I have encountered a little problems with it taught. Nothing major but I just
taugth I would share since it migth be of interest to you.
I have an heavily multithreaded process that runs on a really under powered
server. All those threads access the StringEscapeUtils.escapeXml() methods
pretty much at the same time. What happens is that by the time the Second or
Third Thread calls the StringEscapeUtils.escapeXml() the static initialization
in the Entities.java class has not completed yet. That block in particular.
static
{ XML = new Entities(); XML.addEntities(BASIC_ARRAY); XML.addEntities(APOS_ARRAY); }I don't get a NullPointer so it seems that XML = new Entities() is actually
being executed before the other Thread starts but the
XML.addEntities(BASIC_ARRAY) on the other hand is not executed before the other
thread starts. So when the second or third thread calls the
StringEscapeUtils.escapeXml() it doesn't escape the BASIC_ARRAY or APOS_ARRAY
entities. To fix it, in my code, I just make sure to call
StringEscapeUtils.escapeXml() before I start any threads and it solve the
problems but if anyone is ever to re-work the class this might be something to
look at.
Just to share.
Thank
David
