I want to use a webservice in C code. I am trying to make a client. I need something to do what Axis2java does and generates the classes from a wsdl files.
I found that Axis2c makes (.c) files generated from wsdl file.
I downloaded it from here . unzipped it. I created the environment variable for AXIS2C_HOME and I created AXIS2C_CLASSPATH.
but I can't make it work.
when I type this command :
WSDL2C -uri -ss -sd -d none -u -f -o
I get this error :
echo off
Error: Could not find or load main class org.apache.axis2.wsdl.WSDL2C
how can I solve this problem. and please tell me how to use this Axis2c tool properly.
Thank you in advance.
#loentar : I installed Axis2/Java and I set the environment variable for it. now I run the wsdl2c.bat I get this :
E:\dev\Tools\axis2c-bin-1.6.0-win32\bin\tools\wsdl2c>WSDL2C.bat
E:\dev\Tools\axis2c-bin-1.6.0-win32\bin\tools\wsdl2c>echo off

after that I run this command :

-u -uw

Unrecognized option: -uri
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
what can I do ?
I'm using windows 8 by the way.
In addition to Axis2/C you must have Axis2/Java installed.
AXIS2_HOME must point to Axis2/Java installation.
For details please see README of codegen.
The complete list of commands to create and compile client is:
# create stubs
sh $AXIS2C_HOME/bin/tools/wsdl2c/WSDL2C.sh -uri Calculator.wsdl -u -uw
# implement main() in src/your_client.c
# see samples/codegen/client/calculator for example
# compile and link client
gcc -o calculator_client src/*.c -I$AXIS2C_HOME/include/axis2-1.6.0 -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver -ldl -Wl,--rpath -Wl,$AXIS2C_HOME/lib
I set the envinroment variable for JAVA_HOME, AXIS2_HOME, AXIS2C_HOME, and added their lib folder to CLASSPATH. after running this command:
WSDL2C.bat -uri hello.wsdl -u -uw
I got this message:
echo off
Error: Could not find or load main class org.apache.axis2.wsdl.WSDL2C
I found the solution myself. :)
I double checked if I had created the environment variable for AXIS2_HOME and I saw that it is there, correctly.
in spite of it's existence I tried to set it again in command prompt. so I typed:
SET AXIS2_HOME=E:\dev\Tools\axis2-1.6.2
then I typed the command for WSDL2C code generator:
WSDL2C.bat -uri hello.wsdl -u -uw
And BAM ! it worked properly.
Now I can generate C files from WSDL file.

After booting SWUpdate yocto-generated image for the first time, executing swupdate results in error message:
Error parsing configuration file: 'globals' section missing, exiting.
I tried to strictly follow SWUpdate's documentation, but it gets short when it comes to yocto integration. I'm using meta-swupdate, meta-swupdate-boards, and meta-openembedded layers together with poky example repository all at Kirkstone tag, building via bitbake update-image and having modyfied local.conf as:
MACHINE ??= "raspberrypi4-64"
ENABLE_UART = "1"
RPI_USE_U_BOOT = "1"
IMAGE_FSTYPES = "wic ext4.gz"
PREFERRED_PROVIDER_u-boot-fw-utils = "libubootenv"
IMAGE_INSTALL:append = " swupdate"
Is there anything else I need to modify to generate the configuration file and be able to run SWUpdate binary properly?
Side question: In the documentation, it's recommended to append swupdate-www to achieve a better web server. However, if I append it, there is no swupdate-www binary inside the `/usr/bin' directory.
As with other recipes folders the recipes-support/swupdate/swupdate/raspberrypi4-64 folder was missing inside the meta-swupdate-boards layer. Therefore, an empty config file was always generated. After adding this folder and all related files, strongly inspired by raspberrypi3 folder, the error was gone and swupdate -h provided the expected output.
There was also one new error during build process thrown by yocto. It was related to missing systemd requirement and was solved by adding:
DISTRO_FEATURES_append = " systemd"
to local.conf
I added iptables package to my device image, using CORE_IMAGE_EXTRA_INSTALL += "iptables".
I tried to run it on the device and get the following error message:
modprobe: FATAL: Module ip_tables not found in directory /lib/modules/4.9.11-1.0.0+gc27010d
iptables v1.6.1: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Seems like I have missing kernel module.
Need your help in adding standard kernel module to the image (Where can I find all modules files and how should I add and load it to the image).
You must add the iptables module to your kernel. I had the same problem and I could solve it with these steps:
Run bitbake -c menuconfig virtual/kernel
Activate CONFIG_IP_NF_IPTABLES module (you can search its location on that menu typing slash '/').
Save it and run bitbake -c savedefconfig virtual/kernel for saving that file as a defconfig.
Copy defconfig file from returned path to yocto-distro/layer-name/recipes-kernel/linux/files/ (make this directory if it does not exist).
Create a .bbappend file inside yocto-distro/layer-name/recipes-kernel/linux/ with the same name as your original recipe file from meta layer.
Edit your file and append lines below:
SRC_URI += "file://defconfig"
KERNEL_DEFCONFIG = "${WORKDIR}/defconfig"
FILESEXTRAPATHS_prepend := "${THISDIR}/files"
~
Relaunch bitbake your-image-name
It worked on my situation. Btw, I got that info from the following webs:

Have a nice day! :D
Running chef-solo (Installing Chef Omnibus (12.3)) on centos6.6
My recipe has the following simple code:
package 'cloud-init' do
action :install
end
log 'rpm-qi' do
message `rpm -qi cloud-init`
level :warn
end
log 'yum list' do
message `yum list cloud-init`
level :warn
end
But it outputs the following:
- install version 0.7.5-10.el6.centos.2 of package cloud-init
* log[rpm-qi] action write[2015-07-16T16:46:35+00:00] WARN: package cloud-init is not installed
[2015-07-16T16:46:35+00:00] WARN: Loaded plugins: fastestmirror, presto
Available Packages
cloud-init.x86_64 0.7.5-10.el6.centos.2 extras
I am at a loss as to why rpm/yum and actually rpmquery don't see the package as installed.
EDIT: To clarify I am specifically looking for the following string post package install to then apply a change to the file (I understand this is not a very chef way to do something I am happy to accept suggestions):
rpmquery -l cloud-init | grep 'distros/__init__.py$'
I have found that by using the following:
install_report = shell_out('yum install -y cloud-init').stdout
cloudinit_source = shell_out("rpmquery -l cloud-init | grep 'distros/__init__.py$'").stdout
I can then get the file I am looking for and perform
Chef::Util::FileEdit.new(cloudinit_source.chomp(''))
The file moves based on the distribution but I need to edit that file specifically with in place changes.
Untested code, just to give the idea:
package 'cloud-init' do
action :install
notifies :run,"ruby_block[update_cloud_init]"
end
ruby_block 'update_cloud_init' do
block do
cloudinit_source = shell_out("rpmquery -l cloud-init | grep 'distros/__init__.py$'").stdout
rc = Chef::Util::FileEdit.new(cloudinit_source.chomp(''))
rc.search_file_replace_line(/^what to find$/,
"replacement datas for the line")
rc.write_file
end
end
ruby_block example taken and adapted from here
I would better go using a template to manage the whole file, what I don't understand is why you don't know where it will be at first...
Previous answer
I assume it's a compile vs converge problem. at the time the message is stored (and so your command is executed) the package is not already installed.
Chef run in two phase, compile then converge.
At compile time it build a collection of resources and at converge time it execute code for the resource to get them in the described state.
When your log resource is compiled, the ugly back-ticks are evaluated, at this time there's a package resource in the collection but the resource has not been executed, so the output is correct.
I don't understand what you want to achieve with those log resources at all.
If you want to test your node state after chef-run use a handler maybe calling ServerSpec as in Test-Kitchen.
After successfully installation of Apache2(2.4.4) i tried to start https server but i am getting below error
bimlesh#server:/usr/local/apache2/bin$ ./apachectl start

I looked at /usr/local/apache2/modules/ and really those .so files are not available.
Can anyone please help that how to get rid off.
if i look at /usr/local/apache2/modules/ folder then i see:(no .so files available)

Run
find / -type f -name mod_authn_core.so
or install updatedb ( mlocate, slocate, findutils or sth ) if needed and run
updatedb
and then ( or before )
locate mod_authn_core.so
To find out if these files are somewere else than they should be, and possibly fix location with symbolic link or moving files where they're expected to be.
If there is no file you need, you may need to comment it in httpd.conf ( if it's specific module ), or (re)install apache package(s). I believe mod_authn_core should be in basic package, not in separate module though. Possibly someone removed it blindly or accidentally, or some intruder messed up with system, or disk got broken or whatever else.
PS. Modules usually are under "lib" e.g. /usr/local/lib/apache2 or /usr/lib/apache2, or /usr/lib/apache2/modules or similar, not in /usr/local/apache2/modules, though it usually depends on compilation of package..
You might also run
apache2ctl -t -D DUMP_VHOSTS
to find out what modules were compiled as shared or static. You should also include information about distribution, and note you're building/installing from source.
Also, have look here: http://httpd.apache.org/docs/2.4/install.html#configure
I'm working with net-snmp C API , i create a MIB file ( containt a table of information ).
After that i used the mib2c that gives me two file "myproject.h" and "myproject.c"
I copy this two files in the directory : /net-snmp/agent/mibgroup
and i compile like this :
1) ./configure --with-mib-modules=myproject
2) make
3) sudo make install
and from a terminal i run this command : snmpd -f -L -Dmyproject
and i get the message below : registered debug token myproject,1
Turning on AgentX master support
NET-SNMP version 5.7.2
My question is :
that when i try to run snmptable for this table i get the messsage : NO ENTRIES
and when i try to make snmpset to this table : i get this massage
Error in packet. Reason: notWritable (That object does not support modification)
*NOTE : in my file myproject.c i followed the example given by the net-Snmp :data_set.c
http://www.net-snmp.org/dev/agent/data__set_8c-example.html
but my table has not been initialisated
please i need help
thanks in advance
thanks K1eran for your reply .
the problem that i have it's not because of a badcommunity , here is my community configuration in the file of snmpd located in /usr/local/share/snmp:
full access from the localhost
rocommunity public localhost
rwcommunity private
really i don't know what is the problem ?
Possibly related to community strings i.e. snmpset's -c flag . It would be better to see details of snmpset and snmptable commands however as described at :
net-snmp snmpset tutorial ...
Note that if you don't have write permission to the object ...
% snmpset -v 2c -c badcommunity test.net-snmp.org ucdDemoPublicString.0 s "hello"
Error in packet.
Reason: notWritable
`
In snmpd.conf file the "#rocommunity public localhost " default settings will be commented(meaning localhost public not permitted read/write),
so
UnComment the "rocommunity public localhost" and change to "rwcommunity public localhost" then restart the snmpd service and check
