org.apache.jasper.jasperexception: java.lang.nullpointerexception monday, august 19, 2013, 09:19 pm - programming posted by administrator if your server can startup normally but when you try to access any jsp and the pages show the following exception. java.lang.nullpointerexception org.apache.jsp.index_jsp._jspinit(index_jsp.java:26) org.apache.jasper.runtime.httpjspbase.init(httpjspbase.java:52) org.apache.jasper.servlet.jspservletwrapper.getservlet(jspservletwrapper.java:164) org.apache.jasper.servlet.jspservletwrapper.service(jspservletwrapper.java:338) org.apache.jasper.servlet.jspservlet.servicejspfile(jspservlet.java:313) org.apache.jasper.servlet.jspservlet.service(jspservlet.java:260) javax.servlet.http.httpservlet.service(httpservlet.java:717) com.pahome.filter.characterencodingfilter.dofilter(characterencodingfilter.java:18) org.tuckey.web.filters.urlrewrite.urlrewritefilter.dofilter(urlrewritefilter.java:738) com.pahome.filter.checkloginfilter.dofilter(checkloginfilter.java:173) com.pahome.filter.characterencodingfilter.dofilter(characterencodingfilter.java:18) at line 26 it usually show something like this. _el_expressionfactory = _jspxfactory.getjspapplicationcontext(getservletconfig().getservletcontext()).getexpressionfactory(); it usually means that your web-inf contain duplicated jars especially jsp-api.jar and servlet-api.jar . remove them and restart your server will solve the problem. 11 comments ( 189 views ) | permalink | ( 2.9 / 649 ) configure generates .infig.status: error: cannot find input file tuesday, may 7, 2013, 11:31 am - system posted by administrator if you see error .infig.status: error: cannot find input file during ./configure it is properly due to msdos return character issue. if you system have dos2unix then just simple convert configure.ac/configure.in. if you don't have unix2dos ... you can try to use vi and run set ff=unix wq then run autoreconf -vif after that you can run configure again. btw it is suggest to also convert the shell scripts, sometimes they will also cause problems. 2811 comments ( 34653 views ) | permalink | ( 3 / 712 ) java outofmemoryerror cont. thursday, november 17, 2011, 09:00 pm - system posted by freddy chu if you still face the problem of java.lang.outofmemoryerror: permgen space event you have increase the -xx:maxpermsize. you can try the following jvm args. -xx:+cmsclassunloadingenabled -xx:+cmspermgensweepingenabled usually only java web container like tomcat / jboss / jetty with many contexts will need that flag. but remember enabling this will decrease the performance. use with care. p.s. java 1.6 seems do not support cmspermgensweepingenabled. 2 comments ( 176 views ) | permalink | ( 3.1 / 44 ) java out of memory problems sunday, september 18, 2011, 02:31 pm - programming posted by freddy chu java heap java.lang.outofmemoryerror: java heap just simply apply -xmx will fix the issue. but notice that one thing there have max. value for difference os. e.g. 32bit windows around 2g 32bit linux around 2.5g 64bit i only tried to use 4g, the limit seems much higher than 32bit systems. permgen space java.lang.outofmemoryerror: permgen space presenting the permanent generation by my understanding, permgen space is for loading classes specifications. usually you will not able to see this exception. expecte that you have many lib need to be load and use. using jboss with more than 1 big web application may hit this. you can change this limit by using -xx:permsize and -xx:maxpermsize e.g. -xx:permsize=128m -xx:maxpermsize=128m gc overhead limit exceeded i think this is most uncommon exception that will be hitted java.lang.outofmemoryerror: gc overhead limit exceeded excessive gc time and outofmemoryerror the parallel collector will throw an outofmemoryerror if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an outofmemoryerror will be thrown. this feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. if necessary, this feature can be disabled by adding the option -xx:-usegcoverheadlimit to the command line. source the best way is to solve the coding problem. it is believed that the code have genereated too many trivial object. especially in loops, if that is the case rather reuse the object than new an object. if you really don't want to change the code or you cannot found the problem you can try the following way. hopefully it will solve the issue, but not the best way and may require a long time to finish. jvm have 3 difference garbage collectors you can try switching between them. serial collector single processor jvm flag: -xx:+useserialgc parallel collector high throughput sometimes with pause jvm flag: -xx:+useparallelgc concurrent collector low lag time & moderate throughput jvm flag: -xx:+useconcmarksweepgc -xx:+useparnewgc 3019 comments ( 9792 views ) | permalink | ( 2.9 / 4398 ) my apache production checklist sunday, february 20, 2011, 04:23 pm - system posted by freddy chu apache (httpd) lower keepalivetimeout default usually around 15 but i will choose from 5-10 but remember do not set the value too low as it will cause tcp overhead reduce extra dns lookup for log hostnamelookups off disable directory listing remove "indexes" from options disable .htaccess files reduce file io to search and access permission files, put all access control into your apache configuration files just simply comment out all accessfilename lines make sure apache is not run by root remember to check the "user" and "group" in configure file hide system information servertokens prod serversignature off if you really want to hide the name of apache, you will need to modify the source code and compile for yourself. i believe it is not a necessary step as there still have many ways to discover your web server easily. disable weak cipher sslprotocol -all +sslv3 +tlsv1 sslciphersuite all:!adh:rc4+rsa:+high:+medium:!low:!sslv2:!export limit the use of mod_status if you really need that better change the location to non default links and make sure it is protected by source host or any authentication turn on followsymlinks but disable symlinksifownermatch which reduce disk io to check the file type but make sure that nobody put links in your server that point to your private files options followsymlinks remove "symlinksifownermatch" from options enable compress module (if application do not implement compression.) <location /> # insert filter setoutputfilter deflate # netscape 4.x has some problems... browsermatch ^mozilla/4 gzip-only-text/html # netscape 4.06-4.08 have some more problems browsermatch ^mozilla/4\.0[678] no-gzip # msie masquerades as netscape, but it is fine # browsermatch \bmsie !no-gzip !gzip-only-text/html # note: due to a bug in mod_setenvif up to apache 2.0.48 # the above regex won't work. you can use the following # workaround to get the desired effect: browsermatch \bmsi[e] !no-gzip !gzip-only-text/html # don't compress images setenvifnocase request_uri \ \.(?:gif|jpe?g|png)$ no-gzip dont-vary # make sure proxies don't deliver the wrong content header append vary user-agent env=!dont-vary </location> disable all useless apache modules in some os the default config files include many useless moduels e.g. ldap_module proxy_ajp_module proxy_balancer_module proxy_connect_module proxy_ftp_module proxy_http_module proxy_module speling_module install some protection modules (optional) mod_securitye mod_evasive os disable access time update set noatime to your web document root if your os support e.g. /dev/md0 /var/www ext3 defaults,noatime 0 0 tune network options of the os net.core.netdev_max_backlog = 3000 net.core.rmem_default = 16777216 net.core.rmem_max = 16777216 net.core.wmem_default = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net
