I've worked through the "Integrating Data" guide on the Spring website and have been trying to determine how to use configuration settings (substitution) in the integration.xml file rather than hard code various items. This is primarily driven by a desire to externalise some of the configuration from the XML and take advantage of Spring Boot's ability to allow for externalised configuration.
I've been trying to determine the solution for a while now and thought it's likely to be an easy answer (for those who know how).
In the snippet below (taken from the guide) I've used ${outputDir} as a placeholder for a configuration item I'll pass into the application:
<file:outbound-channel-adapter id="files"
mode="APPEND"
charset="UTF-8"
directory="${outputDir}"
filename-generator-expression="'HelloWorld'"/>
Essentially, I'm trying to determine what I need to do to get the ${outputDir} substitution working.
As part of working through the problem I reduced the code down to a demo that I've uploaded to BitBucket:
integration.xml will just copy files from a file:inbound-channel-adapter directory to a file:outbound-channel-adapterdirectory
The Application class uses Spring Boot to load the configuration into a DemoIntegration instance and it's the fields in that instance that I'd like to substitute into integration.xml at runtime.
Unless I'm mistaken (when I get this to work) I should be able to override the inputDir and outputDir items in integration.xml.
Your integration.xml references ${inputDir}, which is not there.
Just to make it work with the existing config, add/change the application.properties file in your classpath with inputDir=/tmp/in and outputDir. This way it matches with your used vars in the config file.
If you want to stick with your naming, then change the XML to use ${demo.inputDir}. These are the names you are using in your existing application.properties.
And if you want to stick to your #ConfigurationProperties, then you can put #{demoConfigration.inputDir} in the XML to access the bean, where your config is stored. Note, that your code currently fails (at least for me) as you basically define the bean twice (once per #EnableConfigurationProperties and once by #ComponentScan+#Component on the config.

I have two questions about cucumber frame work.
1-My .features files are not converting into feature format and showing as plan text file even though it works fine and I can run my TestRunner.
2- I have saved my all TestRunner files into a package Runner but in TestRunner file I have to give full path of my feature file in order to run TestRunner. e.g features= "Features" not working but
features="C:\Users\FourStar1\eclipse-workspace\com.freeTourTest\src\main\java\Features2\Addusers.feature"
works.
Take a careful look at the casing of your directory and package names. It's important you are consistent with these. It makes it easier to spot mistakes. Using lowercase is recommended.
Additionally tests and test resources should be put under src/test/java and src/test/resources respectively. Feature files are resources and will not be copied over target if you put them under java.
I would suggest learning the maven project layout by heart. It makes everything easier then making up your own organization.
I am using Liferay 6.2 GA5 Community Edition.
Sample case I have 2 entities in my service.xml, let's say entity A & B.
When I run Service Builder then it will generate many JAVA files in my source code, and also generate JAR file located in
".\my-app\liferay-plugins-sdk-6.2\portlets\my-app-portlet\docroot\WEB-INF\lib\my-app-service.jar"
I open it with 7-zip, and I can see in package com.mycompany.myapp.model contains classes of entity A & B.
Then I try to remove entity A in service.xml, and I have removed the corresponding JAVA files generated in my source code, then I run Service Builder again, but inside my-app-service.jar, entity A is still exist.
How do I completely remove it from JAR file? because in my case, Service Builder will not remove it, although I have remove generated JAVA files manually.
ServiceBuilder is a code generator, thus it only generates new code.
If you want to get rid of the once generated code, there's a lot more than just the java classes to get rid of: Spring configuration, Hibernate configuration etc. are there as well for you to take care of. All of these will have to be deleted manually. And if the code still remains in the jar, good old ant clean (or whatever build environment you use) should get rid of the my-app-service.jar file (which you otherwise also can also just delete manually, so that it will be rebuilt next time a build process or ServiceBuilder runs)
I recommend searching for occurrences of A in all your project's files to see if you still find leftovers, because otherwise some component might complain at runtime that a declarated class can't be found.
At this location in this jar file alfresco-remote-api-5.0.d.jar\alfresco\templates\webscripts\org\alfresco\slingshot\node-browser\ there is a webscript. But this webscript consist to 2 files (node-browser.get.desc.xml and node-browser.get.json.ftl ) There isn't the node-browser.get.js file.
I want to know what is done in this fil. I want to select categories and include certains aspects (i have added to categories) in the selection.
Thank you.
Javascript file is not mandatory while creating webscript.
Below is the URL of source file which is getting called on your specified webscript.
https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/COMMUNITYTAGS/V5.0.d/root/projects/remote-api/source/java/org/alfresco/slingshot/web/scripts/NodeBrowserScript.java
Below is context file for java file.
https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/COMMUNITYTAGS/V5.0.d/root/projects/remote-api/config/alfresco/web-scripts-application-context.xml
check bean with webscript.org.alfresco.slingshot.node-browser.node-browser.get
Id.
you need to change in that if you want to customize it.
Usually a webscript is made of 3 parts:
a description file (in your case node-browser.get.desc.xml) which
uses a description language to define many aspects of the
webscript, like security, transaction management and so on
a Server-Side Javascript js file that consists of the business logic that is performed by
the script. In your case you don't have the node-browser.get.js file
because this happens to be a Java backed webscript, that is a
webscript whose business logic is written in Java and not in
Server-Side Javascript.
a Freemarker Template file, node-browser.get.json.ftl, which contains
the presentation logic (view) that has to show the results of the invocation.
In order to achieve what you're looking for about selecting categories and include certains aspects, you'd better learn more about how webscripts work and moreover how to configure/customize Alfresco's interface.
You'd better look at these tutorials in order to get more info.
I'm working on a project and we want to handle our logging using log4j. I am running into some issues that I am not able to easily resolve looking at the log4j docs, or other documentation online.
I get the basic idea of putting logging code throughout the codebase and then having the properties file assort the logged data into a hierarchy of appenders and how to write out to a file. That's fine. This basically allows me to create greppable log files in one hard coded folder, such as this:
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
But I have two basic questions: I want to have the log location be dynamic, such as:
log4j.appender.R.File={$processDir}/example.log
Also, every time the user runs this app, a folder will be created with the output files. I would like to have the log file be placed there, and I'm not sure how to accomplish that.
The other issue (although I think this will be a lot easier once the first issue is addressed...) is about creating a formatted log that does not necessarily reflect the process of how the app ran...for example, a title, followed by a list of all input files, a list of all output files, any warnings encountered.
I think for that I would create an object that implemented ObjectRenderer and write a doRender method that gave me the info I wanted.
Does that sound correct?
Thanks!
You can use variable with this syntax
log4j.appender.R.File=${processDir}/example.log
You must define the variables as system properties (es. -DprocessDir=...) or manually (after creating folder) with
System.setProperty("processDir",logDir);
After installing my files using WIX 3.5 I would like to changes some values in one of my xml files.
Currently there are multiple entries like this:
<endpoint address="net.tcp://localhost/XYZ" .../>
I would like to change the localhost to the real servername wich is available due to a property. How can I perform this replacement on each entry inside this xml file? Is there a way to do this without writing an own CA?
Thanks in advance!
XmlConfig and/or XmlFile elements are your friends here.
UPDATE: Well, according to the comments below, it turns out that only part of the attribute (or element) value should be changed. This seems not to be supported by either of two referenced elements.
I would take one of the two approaches then:
Use third-party "read XML" actions, like this one
It's better than creating your own because you can rely on deeper testing in this case
Teach your build script to control the string pattern
Let's say you put `net.tcp://localhost/XYZ` to build file and your code is pointed out to take this value as a string pattern to use at install time. For instance, keep the string pattern as a Property in your MSI package. When it changes, e.g. to `net.tcp://localhost/ABC` you'll have to change nothing in your action. In this case from a XMLFile perspective you always know your FROM and TO attribute values.
If your XML configuration file is not large, you can load the file into memory and perform replace using JScript.
var s = "<endpoint address=\"net.tcp://localhost/XYZ\" .../>";
var re = /"net.tcp:\/\/localhost\//g;
var r = s.replace(re, "\"http://newhost.com/");
Here s is your complete XML file, re is the regular expression, and r would contain the result or replace.
You can read and write to public properties of Windows Installer using JScript. Yet there's still one problem: you have to read your XML file and to write it back to disk. To do it, you can use Win32_ReadFile and Win32_WriteFile custom actions from the AppSecInc. MSI Extensions library referenced by Yan in his answer.
However, it could be easier to write a complete Custom Action which will load your XML configuration file, do the replace, and write the file back to disk. To do it you can use XSLT and JScript (see an example code).
InstallShield has a built-in data driven custom action called Text Search. It basically allows for RegEx style replacements like what you are describing.
WiX doesn't have this functionality but you could write a custom action ( say using C#/DTF ) to do it for you.
There nothing in Wix, you can do to change something in a file without using a custom action. If you don't want to use CA, you can consider saving the settings in some other place e.g. User's registry and always read that setting from there
