how bundle version @ running tomcat?

i seek getclass().getpackage().getimplementationversion() returns null. guess because war wasn't yet packaged , tomcat executes .classes (aka exploded war). meta-inf\manifest.mf nowadays in final war, not in target\<project.name>\meta-inf folder

java.lang.package

package objects contain version info implementation , specification of java package. versioning info retrieved , made available classloader instance loaded class(es). typically, stored in manifest distributed classes.

related how maven artifact version @ runtime?

update. before have added configuration war build. when running tomcat eclipse, null.

<plugin> <artifactid>maven-war-plugin</artifactid> <version>2.1</version> <configuration> <archive> <manifest> <adddefaultimplementationentries>true</adddefaultimplementationentries> <adddefaultspecificationentries>true</adddefaultspecificationentries> </manifest> </archive> <!-- moves classes \web-inf\classes new jar <archiveclasses>true</archiveclasses> --> </configuration> </plugin>

solved by 1) creating meta-inf\manifest.mf in webapp folder mvn war:manifest 2) coding

version = getclass().getpackage().getimplementationversion(); if (version==null) { properties prop = new properties(); seek { prop.load(getservletcontext().getresourceasstream("/meta-inf/manifest.mf")); version = prop.getproperty("implementation-version"); } grab (ioexception e) { logger.error(e.tostring()); } } logger.info("starting app version "+version);

thanks @javadude reply @ how read manifest file webapp running in apache tomcat?

java eclipse maven tomcat manifest.mf

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
