How to log useful error if scala play config files missing? - scala

Is it possible to give a better error message if the config filename is mistyped when using scala play.api.Configuration
e.g. if I run my application with sbt run -J-Dconfig.file=conf/my-config.conf but the file is actually called my_config.conf, there is no error raised about file not found, but instead the first time the error is raised is when applicationConfig.has(configPath) is called, at which point it is not clear how to determine programatically the difference between a missing config value in the file or a missing config file.


Here is what I do:
Wrap the configuration in a Config-Class.
Initialize that class on startup.
Log all property - values.
This will log exceptions on Startup. Here is an example: AdaptersContext.scala
As a remark:
If you have your config-file in the conf directory (on classpath), use:
config.resource=demo.conf

Install4j Check JDBC Connection Action SetDriver

In Install4j i call the CheckJdbcConnectionAction action and execute it.
But it dont works.
here is the code:
CheckJdbcConnectionAction checkConnection = new CheckJdbcConnectionAction();
checkConnection.setDriverClassName("org.postgres.Driver");
here is the log:
[ERROR] com.install4j.runtime.beans.actions.jdbc.CheckJdbcConnectionAction: Driver class org.postgres.Driver was not found. Add the JAR file to the "Installer->Custom code & resources" step.
I added the jar (postgresql-42.2.0.jre7.jar) into "Installer->Custom code & resources" but it still gives me the same error.
I changed the Value of setDriverClassName to postgresql-42.2.0.jre7 but still the same error
Whats the next step to get it work?
thanks

The driver class name is wrong, it should be org.postgresql.Driver.
Also, if you really want to execute this action programmatically, you have to set the properties setJdbcUrl(...), setUser(...) and setPassword(...) as well.

How to resolve undef error in ejabberd hook

I have added a customized module named mod_confirm_delivery in ejabberd which has compiled and added successfully but when i am sending a message an error is coming in my ejabberd error log file, That is:
2016-03-15 17:03:38.306 [error] <0.2653.0>#ejabberd_hooks:run_fold1:368 {undef,[{mod_confirm_delivery,send_packet,[{xmlel,<<"iq">>,[{<<"xml:lang">>,<<"en">>},{<<"type">>,<<"get">>},{<<"id">>,<<"aacfa">>}],[{xmlcdata,<<"\n">>},{xmlel,<<"query">>,[{<<"xmlns">>,<<"jabber:iq:roster">>}],[]},{xmlcdata,<<"\n">>}]},{state,{socket_state,gen_tcp,#Port<0.58993>,<0.2652.0>},ejabberd_socket,#Ref<0.0.1.25301>,false,<<"12664578908237388886">>,undefined,c2s,c2s_shaper,false,false,false,false,[verify_none,compression_none],true,{jid,<<"test1">>,<<"localhost">>,<<"D-5">>,<<"test1">>,<<"localhost">>,<<"D-5">>},<<"test1">>,<<"localhost">>,<<"D-5">>,{{1458,41617,630679},<0.2653.0>},{2,{{<<"test2">>,<<"localhost">>,<<>>},{{<<"test1">>,<<"localhost">>,<<>>},nil,nil},nil}},{2,{{<<"test2">>,<<"localhost">>,<<>>},{{<<"test1">>,<<"localhost">>,<<>>},nil,nil},nil}},{0,nil},undefined,undefined,{userlist,none,[],false},c2s,ejabberd_auth_internal,{{127,0,0,1},41928},[],active,[],inactive,undefined,undefined,1000,undefined,300,300,false,0,0,true,<<"en">>},{jid,<<"test1">>,<<"localhost">>,<<"D-5">>,<<"test1">>,<<"localhost">>,<<"D-5">>},{jid,<<"test1">>,<<"localhost">>,<<>>,<<"test1">>,<<"localhost">>,<<>>}],[]},{ejabberd_hooks,safe_apply,3,[{file,"src/ejabberd_hooks.erl"},{line,382}]},{ejabberd_hooks,run_fold1,4,[{file,"src/ejabberd_hooks.erl"},{line,365}]},{ejabberd_c2s,session_established2,2,[{file,"src/ejabberd_c2s.erl"},{line,1268}]},{p1_fsm,handle_msg,10,[{file,"src/p1_fsm.erl"},{line,582}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,240}]}]}
I have ejabberd 16.02.26 and my module code is:
mod_confirm_delivery.erl
This module is working fine with ejabberd 2.1.13 but i want to upgraded my ejabberd. I can't understand what is the problem and how can I resolve this error.

undef error means the function or module is not found. The most likely error is that the mod_confirm_delivery.beam file is not in Erlang VM path.
You should try moving the compiled beam file with other ejabberd beam files or try setting the path used to launch Erlang to the directory where your mod_confirm_delivery.beam file is located. This is the -pa option of the Erlang VM.
If your code if in right place, other option is that the function is undefined. The hook tries to call mod_confirm_delivery:send_packet/4. Your code is wrong as it indeed does not defined send_packet/4 but only send_packet/3. You need to update your code to match new signature for user_send_packet hook:
user_send_packet(Packet, C2SState, From, To) -> Packet
In case of doubt, you can refer to official hook list in ejabberd documentation: https://docs.ejabberd.im/developer/hooks/

Failed to load kafka module

I am trying out the nxlog kafka out module from below
Link
I get the below error message
ERROR Failed to load module from /usr/local/libexec/nxlog/modules/output/om_kafka.so, /usr/local/libexec/nxlog/modules/output/om_kafka.so: undefined symbol: rd_kafka_topic_new;DSO load failed
ERROR module 'outKafka' is not declared at /usr/local/etc/nxlog/nxlog.conf:65
ERROR route tcproute is not functional without output modules, ignored at /usr/local/etc/nxlog/nxlog.conf:65
I am using :
Nxlog Version - nxlog-ce-2.8.1248
Kafka Version - kafka_2.9.2-0.8.1.1
Latest librdkafka
Also the example programe of librdkafka (rdkafka) for both producer and consumer runs fine so I guess the environment is set correct for librdkafka ,
but am unable to determine what's causing this problem.

The problem is that om_kafka.so is not linked with librdkafka.
You will need this in Makefile.am:
om_kafka_la_LIBADD = $(LIBRDKAFKA) $(LIBNX)
The value of $(LIBRDKAFKA) should be properly set ,normally this is done in configure.in. Otherwise you could just use the full path to the library (.so or .la or .a )

Exception while creating sp.xml using ssoadmin

I am facing this exception when I trying to create the sp.xml using the ssoadmin :
com.sun.identity.cli.CLIException: AdminTokenAction: FATAL ERROR: Cannot obtain Application SSO token.

And I also tried adding something like this in the ssoamdin.bat :
-D"com.iplanet.am.naming.map.site.to.server=https://lb.example.com:443/openam=http://server1.example.com:8080/openam"
But the same exception...
How to fix it?
Thanks in advance,

The 'map-to-site' property is only needed if you have a site configured an the host where you run ssoadm is not able to talk to the siteURL.
You may set -Dcom.iplanet.services.debug.level=message -Dcom.iplanet.services.debug.directory=WRITABLE_EXISTING_DIRECTORY' as JVM options within ssoadm.bat.
You may then look into the debug directory you should find a pointer what's wrong.

The above got sorted in my case when i went to the ssoadmin folder openam/bin and found the ssoadm.bat file and opened it in the edit mode and added the following two lines in the java comaand :
-D"javax.net.ssl.trustStore=F:\tomcatsslkeystore" (tomcat keystore path)
-D"javax.net.ssl.trustStorePassword=tomcatsslkeystore" (tomcat keystore password)

FATAL org.apache.hadoop.conf.Configuration - error parsing conf file: org.xml.sax.SAXParseException

I'm trying to run pig locally, installed using homebrew, to test a script. However, I get the following error when I attempt to run a simple dump from the interactive prompt pig -x local:
2012-07-16 23:20:40,447 [Thread-7] INFO org.apache.pig.backend.hadoop.executionengine.util.MapRedUtil - Total input paths (combined) to process : 1
[Fatal Error] :63:85: Character reference "&#2" is an invalid XML character.
2012-07-16 23:20:40,688 [Thread-7] FATAL org.apache.hadoop.conf.Configuration - error parsing conf file: org.xml.sax.SAXParseException: Character reference "&#2" is an invalid XML character.
The same load/dump works fine on Elastic MapReduce.
I can't find any XML config files, and I've tried with both version 0.9.2 and 0.10.0
What am I missing?
Edit: Just checked a direct download (vs. homebrew) and it doesn't seem to work either

You should check that your Hadoop configuration files have correct configuration data.
Have a look in your hadoop/conf directory.
Have a look inside:
hdfs-site.xml
mapred-site.xml
core-site.xml

Finally worked out what the problem was. I ended up having to use dtruss -p on the pig/java process. This revealed a temporary directory and dynamically generated xml files. Once the temporary directory was discovered, it all fell quickly into place.
It was picking up the proxy excludes from my network connections, which had, as far as I can tell, &#2 (http://www.fileformat.info/info/unicode/char/02/index.htm) embedded in it. How this invalid value came to be in my network preferences in the first place, I haven't the faintest clue.
The value was then being pulled into dynamically generated files, for example /tmp/hadoop-vertis/mapred/staging/vertis-1005847898/.staging/job_local_0001/job.xml.
The offending lines:
<property><name>ftp.nonProxyHosts</name><value>localhost|*.localhost|127.0.0.1|h|*.h</value></property>
<property><name>socksNonProxyHosts</name><value>localhost|*.localhost|127.0.0.1|h|*.h</value></property>
<property><name>http.nonProxyHosts</name><value>localhost|*.localhost|127.0.0.1|h|*.h</value></property>
