[resolved] How to set the Config folder path at runtime?

Anonymous — Sat, 16 Nov 2024 12:56:04 GMT

Hi Shong,
While exporting the job, the source code containing the hard coded value of config folder path. How to pass the path value as a command line argument?
Code Snippet:
-----------------
Instead of this one:
java.io.InputStream inContext = Context.class.getClassLoader()
.getResourceAsStream(
"config/context_0_1/contexts/" + contextStr
+ ".properties");
i need the following oprtions:
java.io.InputStream inContext = Context.class.getClassLoader()
.getResourceAsStream(
contextStr+ ".properties");
or
java.io.InputStream inContext = Context.class.getClassLoader()
.getResourceAsStream(
configpath + contextStr
+ ".properties");

Thanks in advance...

Hi,
You can set up this path value as a context, ie. context.path.
When you execute the jar file, you can directly override a context variable from a commandline using --context-param path=mypath

Hi Shong,
I thought that you didn't understand my scenario. But i got your point. My scenario is to use the context variables in Context file. But path of the context file path should be passed as command line argument. It contains at the executable batch/shell file level.
instead of this one:
java -Xms256M -Xmx1024M -cp classpath.jar: config.sqljdbc_0_1.SQLJDBC --context=Default $*
i need the following one
java -Xms256M -Xmx1024M -cp classpath.jar: config.sqljdbc_0_1.SQLJDBC --context=<filepath>/Default $*
Because the source code cointains the hard coded context path as mentioned in the previous thread.
please see the screen shot below.

It is impossible, the path of .properties is fixed now. You can report a new feature on our bugtracker.
Best regards

If you use tContextLoad or implicit context loading in your jobs rather than the context group values preset within the studio you can specify the location of the file containing your context values at run-time. Within the job, set the location of the file to itself be a context variable and then set that location at run-time e.g.

java -Xms256M -Xmx1024M -cp classpath.jar: config.sqljdbc_0_1.SQLJDBC --context_param contextfile="C:/my context files/contextfileA.txt"

In the screenprint you can see that the Default values of the context have been overridden in running the job by those from c:\program files\vars.txt. The actual location of vars.txt is passed to the job from the command line.

Guys, You look at the below mentioned article:
How to pass the Parameters and context variables through command line
You can also go through following links to know more about context variables
1. Understand Context variables and define their value inside the Job.
2. Define context variables in Repository, which can be made available to multiple jobs.
3. Populate the values of context variables from file. (tContextLoad)
4. Pass context variables or parameters from Parent Job to Child Job.
