I have a Java class that saves a bunch of Java object from a group of Database tables encrypting them and saving to an output file as a backup. The problem I am having is I not sure where to call the Java class from with install4j to be able to perform this task before I do an uninstall of the previous version of the Application. Do I need to do a script or a custom application within instll4j to do this?
Simply add the single class or a JAR file with all the required classes on the "Installer->Custom code & Resources" step. Then, add a "Run script" action to the "Uninstallation" screen or the uninstaller. In the script, you can call your classes directly.

I have a question about eclipse and make. I have created a make environment which acts as follow:
I have a batch file (Start.bat) which SET´s variables for further usage (e.g. SET TOOL_PATH = blabla).
After calling this I use my make.bat <option>, which calls the make.ext -f Makefile.mak <option> with the given option e.g. make.bat all -sj4. The environment variables which are set in Start.bat are very important for the running of the overall make environment.
This works very fine and now I would like to import this in eclipse but I am not familiar with eclipse. I need from eclipse that when I would like to run a make, first the Start.bat is called and then the make.bat <option> is called.
What I need to do?
You can import your project as 'existing make file project'
In the project settings you should be able to define pre-biuld steps and call the batch there or define a specific target (e.g. start) that calls the start batch and is executed before your 'make'.
I dont know exactly at the moment how to do this the best way, but I think you are fast into it.
I'm using code first migrations with my context class in a class library (ie not the startup project) and I want to make batch files for the common operations to save having to pass in the parameters each time I want to add-migration and update-database. I ran the "dir" command in the console and it appears to be in the solution root folder so I have tried creating a .bat,.cmd or .ps1 file in the Solution Items folder but the package manager powershell doesn't seem to be able to find it?
At this very moment I am happening to read this from Bruce Payette's "Powershell in Action" (Wonderful book) so share something with you, lucky guy:
"In this example (Poster: an example in the book), even though hello.ps1 is in the current directory, you had to put ./ in front of it to run it. This is because Powershell doesn't execute commands out of the current directory by default. This prevents accidental execution of the wrong command."
Looks like I needed to just put a ".\" on the beginning of the batch file name - not sure if Powershell requires this to execute?
If I compile a script for distribution as a standalone exe, is there any way I can store settings within the exe itself, to save having to write to an external file? The main incentive for this is to save having to develop an installation process. I only need to store a few bytes.
Also, can resources such as images be compiled into the exe?
Using alternate data streams opens up a can of worms so i wouldn't go that way. Writing back config data into the exe itself won't work as the file is locked for write access during execution.
What i usually do is to store config data under %A_AppData%\%A_ScriptName%\%A_ScriptName%.ini
When the script starts i use IniRead which also provides a default value if the key isn't found - which is the case the script is executing for the first time.
The complementing IniWrite's in a OnExit subroutine/function will create the ini file if necessary.
This way no installation is needed and the config is stored in the proper, familiar place.
The autohotkey forum has dealt with this question before.
In that case, the user didn't want extra files -- period.
The method was to use the file system to save alternate data.
Unfortunately I can't find the post.
A simpler method is to use fileinstall command.
When the script is compiled, the external file is stored within the exe.
When the script executes the same command as an exe, the file is copied to the same
directory as the running script. It is a simple yet effective 'install'.
With a little testing for the config file, the fileinstall command can be skipped.
Skipping the fileinstall could allow changes to be made to the configuration after 'installation'
I have not tried saving settings within the compiled exe file, but I have included resources. I'm not sure which version of AHK you're using or how you are compiling, but I can right-click my scripts to compile. There's an option to compile with options, where you can include resources in your compiled exe.Compile with options
I have a Java rich client desktop app. that I want to distribute on some computers at work, but I've never done something like this before. People aren't too computer-savy at my workplace and since it is a student job, I won't be there for much longer and I'd like it if I could make my program easy to run by making it runnable when people double-click on it.
I also don't want to have to manually install a JRE to have it run. Basically, what I'd like to know is how to make my java application runnable easily by double-clicking (even if it's only on windows, it's okay). I'm pretty sure I'm going to need to package the correct JRE version alongside, but I don't know what's the correct way of doing this.
I read on some sites that you should not package a JRE along with your program because it makes people have multiple different versions, some of which are outdated, and it causes security issues, but this is not a problem in this case since the computers that are going to run my application are not connected to the internet and are only used to run this program anyway.
Somewhat related question: Since my application is currently an Eclipse project, I get my resources such as icons, images, SQLite database (for read and write), etc. using relative paths (e.g.: img/test.png).
Am I going to have to change any of those paths to have them keep working even while packaged?
What you're looking for is a JAR file. In eclipse, it's quite easy to make a Jar file. Specifically, you'll want to right click on your project, go to Export, and then select "Runnable Jar." Be careful with paths to folders. You may need to keep a resources folder next to the Jar file. You may need to provide some more specifics to get an exact answer on that. Typically, a Resources folder is located in the same spot as the JAR file (in the same folder on your computer).
A better option for easy install of a Java app. with a GUI is to launch it using Java Web Start. For the user, JWS is the 'one click' installation option that can (install & launch the app. then) add desktop shortcuts and menu items. A JWS launch would mean some more work for you, but it is a breeze for the end user.
To ensure a suitable JRE is present to run the app., use deployJava.js (see the JWS link for more details). The script would need to be reconfigured to get the JRE installer from your local network - the default is to get it from Oracle.
Most of the resources should be packaged in Jar files and supplied along with the app., but for the DB, use the JNLP ExtensionInstallerService to call the DB installer.
..Java Web Start is kind of a link (or I can make it a shortcut on the desktop) that the users will click to either install the JRE and run the program if the JRE isn't installed, or just run the program if the JRE is present on the computer.
The way it would work is to have a web page on the local intranet. When the user visits the page, the script checks for a suitable JRE.
If it is present, it writes the link to the launch file.
If there is no JRE, or the version is too low, it will guide the user through installing it (just a matter of them clicking 'OK' when prompted). Then it will put the link to the app.
I can then configure the link to grab the JRE from the server on our network.
That's the part where you need to reconfigure the script. AFAIR the script exposes an URL at which to look for JREs - that can be changed to point to a place on the intranet.
..So "Web" is only just in the name, the computers don't have to be connected to the internet to have this work, right?
Yes. JWS is a great launch technology for Java rich clients, but is a poorly chosen name.
To make the problem run by double clicking it you can distribute it as a jar file or a batch file to call the jar file.
For the installation part you can make a batch file that checks if java is present and then call the installer if it isn't.
Edit:
The batch code:
IF DEFINED JAVA GOTO ok
java-installer.exe
GOTO end
:ok
your-application.jar
:end
If you are finding it tough to implement the above mentioned methods. You can proceed with this simple approach.
Create a folder lib at a location. Place all the jars that your application uses into this. If you are able to create a jar for your application, you can very well place your application.jar into the lib folder too. Create a batch file at the same location that will contain the java command for your main class in it. The text within your batch might look something similiar to this :
set path="\lib\"
java -cp %path% package1.package2.MainClass
If you have any other dependencies, for ex: if you use images in your code under img/icon.jpg. Then you just have to shift the img folder to this location too.
Just zip these files using winrar and share it across. Running the batch file after extracting the zip would launch your java MainClass irrespective of the location in which it is placed in the client system.
PS : If you are unable to create a jar for your application and placing it in lib folder, just copy your bin folder with class files and paste it in the location and change the batch file accordingly to look for classes inside bin.
I want to include the Application Loader process in a software installation, to ensure that users get our software installed on their Blackberry by the time our installer software finishes.
I know this is possible, because Aerize Card Loader (http://aerize.com/blackberry/software/loader/) does this. When you install their software, if your Blackberry is connected the Application Loader will come up and force the .COD file to install to the device.
I can't make it work. Looking at RIM's own documentation, I need to:
Place the ALX and COD files into a subfolder here: C:\Program Files\Common Files\Research In Motion\Shared\Applications\
Add a path to the ALX file in HKCU\Software\Research In Motion\Blackberry\Loader\Packages
Index the application, by executing this at the command line: loader.exe /index
Start the force load, by doing this: loader.exe /defaultUSB /forceload
When I execute that last command, the Application Loader comes up and says that all applications are up to date and nothing needs to be done.
If I execute loader.exe by double-clicking on it (or typing in the command with no parameters), I get the regular Application Loader wizard. It shows my program as listed, but un-checked. If I check it and click next, it will install to the Blackberry. (This is the part that I want to avoid, and that Aerize Card Loader's install process avoids.)
What am I missing? It appears that the Aerize installer is doing something different but I haven't been able to ascertain what.
You can do it easily with the following command:
C:\RIM\JDE_4.7.0\bin\JavaLoader.exe -u load <.cod file>
With this command you don't need an alx at all, just the cod file. Look at JavaLoader usage help to see full options.
JavaLoader.exe can upload one code file. What about two or more cod files?
