I was following http://code.google.com/appengine/articles/soap.html to create a Web Service in Google App Engine. After reach item no 4, where i need to run wsgen to generate wsdl file for my Web Service, I found the sample syntax was given for Linux. I managed to find the syntax for Window but when i run it, It creates a package called jaxws but no xsd and wsdl file created. It only creates package com.example.jaxws and no other java files created in side the package.
What I did:
1st I compile the java file in CMD
C:\Smartag_Eclipse_Project\HelloSOAPServer\src>javac com\example\Greeter.java
2nd I run wsgen
C:\Smartag_Eclipse_Project\HelloSOAPServer\src>wsgen -cp . com.example.Greeter -
wsdl
Appreciate if someone could help me on this. Thanks.
Problem solved.
wsgen -cp C:\Smartag_Eclipse_Project\HelloSOAPServer\war\WEB-INF\classes -wsdl -keep -r C:\Smartag_Eclipse_Project\HelloSOAPServer\war -d C:\Smartag_Eclipse_Project\HelloSOAPServer\war\WEB-INF\classes -s C:\Smartag_Eclipse_Project\HelloSOAPServer\src com.example.Greeter

I am using custom Nagios plugins for the first time and am running into this error when I create a service for the plugin.
(No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_load.py, ...) failed. errno is 2: No such file or directory
The plugin works when I run it on the command line, however does not work when it runs within Nagios.
I followed these steps to get the plugin into Nagios
https://assets.nagios.com/downloads/nagiosxi/docs/Managing-Plugins-in-Nagios-XI.pdf
Here is what it looks like in the Nagios UI
The plugin is in the correct path: /usr/local/nagios/libexec and the resource.cfg file has the same path within it.
I tried two separate plugins, both which work on the command line, and the result is the same error.
The error indicates the file location is incorrect, however the plugin is in the specified directory and runs with no errors within that directory.
I am totally stumped and appreciate any help.
For anyone reading this, I solved the problem.
The first time I added the plugin, I forgot to add the python extension. When I updated the already created plugin, Nagios still threw the error.
Once I completely deleted the plugin and re-created it the 'file not found', error went away.
I faced a similar issue when I was trying to add a custom plugin ( I had custom plugins in ruby and python ).
The issue was the missing shebang line at the start of the script (which determines the script's ability to be executed like a standalone executable).
For example, if you have a python plugin custom-plugin.py then make sure this script has shebang at the start of script #!/usr/bin/env python3. Also if you have other scripts (ruby, bash etc.) make sure to add the appropriate path at the start of your scripts.
Also, check the path for plugins Nagios version. For my setup path was /usr/local/nagios/libexec/ and make sure your custom plugin is executable and has correct ownership permissions.
Sample custom template I used :
define command {
command_name check_switch_health
command_line /usr/local/nagios/libexec/check_snmp.rb --host $HOSTADDRESS$ --model "$ARG1$" --community "$ARG2$"
}
The above workaround worked for me.
I need to convert wadl to java pojo, for that i have downloaded apache cxf 3.0.1 version. But when i run wadl2java bat file in my command prompt, i am getting following exception
D:\software\apache-cxf-3.0.1\bin>wadl2java -h
Error: Could not find or load main class org.apache.cxf.tools.wadlto.WADLToJava
Here this script file is looking for WADLToJava class. i have downloaded the apache cxf source distribution, i can see that wadl2java class is there. Please suggest me how i can use apache cxf to generate java files from wadl url.
You need to set CFX_HOME and CLASSPATH environments variables.
CXF_HOME should be your installation dir, in your example;
CXF_HOME=D:\software\apache-cxf-3.0.1\
CLASSPATH is variable used for setting java classpath for wadl2java script, in your windows example;
CLASSPATH=.;%CXF_HOME%\lib\*
I am trying to execute a TestNG Suite file via the command line in order to initiate a regression run.
Currently I am doing this through my Eclipse IDE successfully by right-click on the "testng.xml" file then selecting Run As > TestNG Suite.
However, when I try to run it via the command line, I get an error message. Steps below:
I navigate to the directory where my "testng.xml" file is saved. e.g. C:\Users\xxx\Documents\eclipse projects\Automated Testing\config
Run the command:
java org.testng.TestNG testng.xml
The above command generates the below response:
Error: Could not find or load main class org.testng.TestNG
I tried setting the classpath to include all of the selenium and testNG Jar files as per below:
set classpath C:/Users/xxxx/Downloads/selenium-java-2.25.0/selenium-2.25.0/libs/*
However, this generates the below error message:
Environment variable classpath C:/Users/xxxx/Downloads/selenium-java-2.25.0/selenium- 2.25.0/libs/* not defined
I have looked on the testNG Documentation (http://testng.org/doc/documentation-main.html) and this just says that testNG has to be in your classpath, so now I am a bit stuck. Any help would be greatly appreciated.
Either methods work :)
Method #1
cd C:\Workspace\projectname
java -cp C:\Workspace\projectname\lib\*;C:\Workspace\projectname\bin org.testng.TestNG testng.xml
Method #2
cd C:\Workspace\projectname
set ProjectPath=C:\Workspace\projectname
echo %ProjectPath%
set classpath=%ProjectPath%\bin;%ProjectPath%\lib\*
echo %classpath%
java org.testng.TestNG %ProjectPath%\testng.xml
Thanks #siemic, I have finally got it working now. Basically you just need
to run the two commands below:
set classpath=..\bin;C:\libs\selenium-java-2.25.0.jar;C:\libs\testng-6.0.1-nobsh
noguice.jar;C:\libs*
java org.testng.TestNG
It was the first command that I was having trouble with, so just to elaborate I needed to set the following three items on the classpath:
The BIN Directory of my project. This is because the java files that I have developed are located here.
The Selenium.jar file, this is because I am using the selenium framework
The testng.jar file, needed because this is my unit testing framework
Then finally I used a wildcard to include all other JAR files within my libraries folder. The weird thing
is I needed to fully specificy the name of the selenium and testng jar files, or else the tests don't work. Not too sure why.
Anyway it is working fine now and I am able to execute the tests via the command line.
I am a newbie.
I am trying to publish procedures which return refcursor as webservice.
As webservices do not support ref cursor return type so I chnaged the return type to pl/sql table.
I created the jax rpc in Jdeveloper studio 11.1.2.4.0 and tested it. This runs ok. I need to deploy it on tomcat server and am failing completely.
I copied the war file generated by Jdeveloper to the webapps directory in Tomcat and started Tomcat but this didn't work, as the following exception was thrown:
java.lang.ClassCastException: omsdevconn.MyWebServicetomcatUser cannot be cast to javax.servlet.Servlet
If someone has done it then can I get the steps for the process to deploy it on Tomcat 6.0.37?
Thanks in advance
Download jaxws-rt-2.0-SNAPSHOT.jar and jaxws-2_0.jar
Copy into $CATALINA_HOME/lib folder
Add the following in web.xml under web-app
<web-app>
**<listener>
<listener-class>
com.sun.xml.ws.transport.http.servlet.WSServletContextListener
</listener-class>
</listener>**
............<!--your other servlet definations-->
</web-app>
create sun-jaxws.xml under your applications web-inf folder and configure endpoints.You can have a look at jdeveloper generated xml file to get all the information
sample sun-jaxws.xml
<?xml version="1.0" encoding="UTF-8"?>
<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"version="2.0">
<endpoint name="fromwsdl"
interface="com.foo.yourserviceInterface"
implementation="com.foo.yourserviceClass"
wsdl="WEB-INF/wsdl/youservice.wsdl"
service="YourService"
port="YourServicePort"
url-pattern="/serviceAccessUrl" />
</endpoints>
create war for your application and deploy you application under tomcat/webapps
start tomcat
After starting tomcat you can access the service as
http:/host:port/yourservicename/methodInService
As you are calling oracle plsql code and IF you are using any oracle specific calls like OracleCallabelStatement then on run time you will get class cast exceptions from tomcat datasource when trying to cast callabelstatement to oraclecallabelstatement for that you need to configure oracledatasource in tomcat

Another way to deploy service generated by Jdeveloper when exposing a plsql procedure as webservice
I am not allowed to post more that 2 links so please add and extra "/" after http: to correct the links
This solution uses Apache Axis which allows you to call your web service(which is not exposed as restful) directly from browser by creating a SOAP request behind the scenes and involke the service method giving it soap message.
1)Generate a webservice in Jdeveloper .It will create java files and corresponding ".class" file , "wsdl file" in web-inf and some other xml files. Make a note of LOCATION of .class file and wsdl file.
2)Download eclipse and extract it on your hard drive (It needs java to run So you must have java installed on system .You can download eclipse from
http:/www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/junosr1
3)Download Axis plugin for eclipse from here :
http:/www.apache.org/dyn/mirrors/mirrors.cgi/axis/axis2/java/core/1.6.2/axis2-eclipse-service-plugin-1.6.2.zip
and install it in eclipse. Installation Instructions :
http:/axis.apache.org/axis2/java/core/tools/eclipse/plugin-installation.html
4)Generate the aar file via eclipse axis plugin. Instructions :
http:/axis.apache.org/axis2/java/core/tools/eclipse/servicearchiver-plugin.html#Operation
5)Make following changes in tomcat-user.xml file
<role rolename="tomcat"/>
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<role rolename="manager-jmx"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat,manager-gui,admin-gui,manager-jmx"/>
6)IF YOU ARE USING ORACLE SPECIFIC CLASSES IN CODE (Which most probably Jdeveloper will produce) : Configure a oracle data source in tomcat (server.xml or context.xml). Instructions :
http:/www.oracle.com/technetwork/articles/oem/ucp-jdbc-tomcat-355431.html
Make sure you have ojdbc6.jar and ucp.jar in Tomcat/lib folder.
7)Download axis war file to deploy in tomcat from here :
http:/www.apache.org/dyn/mirrors/mirrors.cgi/axis/axis2/java/core/1.6.2/axis2-eclipse-service-plugin-1.6.2.zip
Unzip the zip , it will have a axis2.war file in it. Put this war file under “\Tomcat\webapps” directory
8)Start tomcat. On tomcat console see if there are any errors in deploying axis. If everything is fine you should be able to see axis page on http:/yourhost:yourport/axis2/
9)Click on Administration link . Enter user id “admin” and password “Axis2” and login
10)Click upload and browse to the location of aar file you generate in step 4 and upload. After it shows you success click on Available service. It takes a bit of time but you should be able to see you service.Click on service to see wsdl to verify
11)Call your service method from browser and cross your fingers and toes.
Note that the link to hit will be something Like
http:/yourhost:yourport/axis2/services/YourServiceName/serviceMethod?arg1=blah&
Make sure your got the arg names right.you should be able to see the correct names from wsdl
I'm having a little trouble understanding how Solr fits in with Jetty, and why I can't seem to get the start.jar in the distribution package to work.
I can run all of the example configurations via java -jar start.jar. However, when I try to run something like the follwing --
java -Dsolr.solr.home=/Users/jwwest/solr -jar $(brew --prefix solr)/libexec/example/start.jar
-- the following error occurs:
java.io.FileNotFoundException: No XML configuration files specified in start.config or command line.
at org.eclipse.jetty.start.Main.start(Main.java:506)
at org.eclipse.jetty.start.Main.main(Main.java:95)
I opened up the start.jar file, and there is a start.config file located inside of the jar which I'm assuming should handle this configuration for me. I'm not understanding why it will work when run from inside of the distribution examples directory, but not outside of it.
You also need to define the jetty.home property. Try:
java -Dsolr.solr.home=/Users/jwwest/solr -jar $(brew --prefix solr)/libexec/example/start.jar -Djetty.home=$(brew --prefix solr)/libexec/example
You can see the effective command line start.jar generates by using the --dry-run command line flag.
java -jar start.jar --dry-run
That will output everything with full path names so you can run it from outside the directory.
Source: http://www.eclipse.org/jetty/documentation/9.0.0.M3/advanced-jetty-start.html
The start.jar is a jetty specific mechanism that works to build out all the classpath requirements for starting up Jetty. It is generally only used in the scope of the jetty distribution. Pulling the start.jar out of the configuration and placing it somewhere else renders the default configuration of the start.config rather moot.
My understanding of Solr is that it bundles itself with a distribution of jetty, placing what it needs to run into the distribution and repackages it as its own. They may have a custom start.config file that further adds its own locations for classpath resources and the like, or not.
The exception you are seeings stems from the start.config file expecting an etc/ directory containing jetty.xml formatted xml files which are used to configure the jetty process.
Jetty being often used in an embedded format has little to do with this issue, it is simply a common use case because jetty is incredibly easy to embed into an application. Embedded instances of jetty rarely (if ever) leverage a start.jar...instead it is up to the embedding application to manage its own classpath.
First, you need to change your folder where start.jar is located, then execute the same command.
Jetty is often used as embedded container. If you want to use the jetty, then a good start would be to copy the example directory and rename it to what you want it to be. The solr directory is the one for basic configuration.
Else it is recommended to use tomcat and the solr.war file.
