how caused , how can solve it?

that can happen if environment doesn't support el 2.2. invoking direct methods parentheses/arguments this

value="#{userbean.getall()}"

is supported since el 2.2, goes hand in hand servlet 3.0. if you're getting exception, can mean you're not deploying servlet 3.0 compatible container, or webapp's web.xml not declared conform servlet 3.0, or webapp's /web-inf/lib littered arbitrarily downloaded servletcontainer-specific jar files originating different servletcontainer make/version doesn't comply el 2.2.

there 2 solutions:

  1. use el 2.1 compatible syntax, works on servlet 2.5 compatible containers:

    value="#{userbean.all}"

  2. upgrade servlet 3.0 compatible container (tomcat 7, glassfish 3, jboss 6, etc), or fix web.xml comply servlet 3.0.

you should make absolutely sure webapp's /web-inf/lib not contain any servletcontainer-specific libraries such el-api.jar , friends (see this related question).

please note not jsf problem @ all. got exception javax.el/org.apache.el package, not javax.faces/com.sun.faces package. means it's el problem. it's saying el syntax wrong. encountered ( didn't expect that. expected characters/operators listed thereafter.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
