i am using liferay 7.4. when i need to using external jar, for example, poi, i will find the maven info, and modify build.gradle and bnd.bnd, after sync gradle, i can using the api.
but when i need using oracle plm api, i have both jars, AgileAPI.jar and pxapi.jar, but i don't know how to put the jars in my module.
i had readed https://liferay.dev/es/blogs/-/blogs/osgi-module-dependencies
, but i do not know how to use it in my case. please help me, thanks in advance.

I have a web (online calculator for an example) which developed by my fellow tem members. Now they want to deploy in PCF using manifests.
Languages used : python, php and javascipt.
I gone through the docs about pcf with manifest.yml
In that I don't have any idea about services and env.
What is that services and how can I find the services for the above project and also how can I find the environment variables?
And tell whether these fields are mandatory to run the project in PCF.
To your original question:
What is that services and how can I find the services for the above project and also how can I find the environment variables? And tell whether these fields are mandatory to run the project in pcf.
Does your app require any services to run? Services would be things like a database or message queue. If it does not, then you do not need to specify any services in your manifest. They are optional.
Similarly, for environment variables, you would only need to set them if they are required to configure your application. Otherwise, just omit that section of your manifest.
At the end of the day, you should talk with whomever developed the application or read the documentation they produce as that's the only way to know what services or environment variables are required.
In regards to your additional questions:
1)And also I have one more query...like in our application we used python ok! In that we use lots of pacakages say pandas,numpy,scipy and so on...how can I import all the libraries into the PCF ??? Buildpacks will contain version only right?
Correct. The buildpack only includes Python itself. Your dependencies either need to be installed or vendored. To do this for Python, you need to include a requirements.txt file. The buildpack will see this and use pip to install your dependencies.
See the docs for the Python buildpack which explains this in more detail: https://docs.cloudfoundry.org/buildpacks/python/index.html#pushing_apps
2)And also tell me what will be the path for my app name if Java I can enclose jar files
For Java apps, you need to push compiled code. That means, you need to run something like mvn package or gradle assemble to build your executable JAR or WAR file. This should be a self contained file that has everything necessary to run your app, compile class files, config, and all dependent JARs.
You then run cf push -p path/to/my-app.jar (or WAR, whatever you build). The cf cli will take everything in the app and push it up to Cloud Foundry where the Java buildpack will install things like the JVM and possibly Tomcat so you app can run.
what should I do for application devloped using pyhton , JavaScript and php....
You can use multiple buildpacks. See the instructions here.
https://docs.cloudfoundry.org/buildpacks/use-multiple-buildpacks.html
In short, you can have as many buildpacks as you want. The last buildpack in the list is special because that is the buildpack which will set the start command for your application (although you can override this with cf push -c if necessary). The non-final buildpacks will run and simply install dependencies.
3) we were using postgresql how can I use this in pcf with my app
Run cf marketplace and see if there are any Postgres providers in your Marketplace. If there is one, you can just do a cf create-service <provider> <plan> <service name> and the foundation will create a database for you to use. You would then run a cf bind-service <app> <service name> to bind the service you create to your app. This will generate credentials and pass them along to your app when it starts. You app can then read the credentials out of VCAP_SERVICES and use them to make connections to the database.
See here for more details:

I have an integration services project in which I use a script component as a source. In the script I read data from a Google sheet and in order to do that I have to authenticate using oauth protocol. I tried to make the necessary references using NuGet but receive errors and have been told that NuGet does not work with SSIS. I have tried to manually make the references and the script builds but when I run the package I get this runtime error:
Could not load file or assembly 'Google.Apis.Auth.PlatformServices,
Version=1.9.3.19383, Culture=neutral, PublicKeyToken=4b01fa6e34db77ab'
or one of its dependencies. The system cannot find the file specified.
Any ideas on how I can get this to work?
I was able to clear this error by adding all dll's in the NuGet package into the GAC and then referencing from there. I then faced a version dependency error which I overcame by adding a binding redirect in my machine.config. Not the most elegant solution but I just needed to make it work and other methods I tried weren't meeting with success.
I receive the error java.lang.NoClassDefFoundError: org.codehaus.jackson.map.ObjectMapper even after adding the Jackson jar files. In Android Studio?
Also tried a few links. Namely this, which did not help.
Edit:
After some research I discovered the root of the error. The dynamo-geo.jar library that is provided by Amazon is inherently flawed in that it refers to some sort of outdated Jackson version. Upon looking in I can see that the class that is called geoJsonMapper refers to a deprecated version of ObjectMapper from the old 1.x.x versions of Jackson. I opened source code from dynamo-geo.jar here and I edited the ObjectMapper import from the outdated version to import com.fasterxml.jackson.databind.ObjectMapper;.
Now the issue I have is I am not sure if there is a way to compile a JAR file in Android Studio? In order to get the newly updated library into my other Android Studio project?
EDIT:
Solution - read this.
If you are using Jackson 2 then you will want to import com.fasterxml.jackson.databind.ObjectMapper instead of org.codehaus.jackson.map.ObjectMapper. You may also have a mix of Jackson 1 and Jackson 2 JAR files in your classpath.
You should be able to fork dynamodb-geo, make your changes, and use Maven to package the new JAR file (run the command mvn clean package). The new JAR file would be located in /dynamodb-geo/target/.
I try to run OSGi application as a standalone application but it fails because it can not find the javax.swing bundle.
OSGi is typically used for web-based "thin" clients.
Java Swing is exclusively used for desktop-based "thick" clients.
Q: Is your UI intended to run in a web browser? Are you sure you need Java Swing at all?
If so, please do this:
1) Look at these links:
http://eclipse.dzone.com/articles/dynamic-swing-osgi-demo
How to create Swing OSGi bundles on AWT EventQueue with Spring DM
2) Please post:
a) the exact error message you're getting
b) Your Java version
c) You Eclipse version (if applicable; otherwise give us some information about your build environment)
I am using gwtprojsonserializer to convert objects to JSON. I've added the version 1.0.4 jar I downloaded from the website http://code.google.com/p/gwtprojsonserializer/ but although the source code on the website includes functionality for serializing arraylists, it is not included in the jar and hence i get the following error:
com.kfuntak.gwt.json.serialization.client.SerializationException: Can't find object serializer for java.util.ArrayList
Does anyone know how I can update the jar or use their latest source code?
Thanks in advance.
Its open source project. The entire source code can be easily downloaded from http://code.google.com/p/gwtprojsonserializer/source/browse/#svn%2Ftrunk
I am assuming the required code for serializing arraylists is in trunk. You can add/remove/modify on you local copy. Build the jar ( it just requires mvn clean install command)
If you are having local repository, use mvn deploy. Ensure your version id is different to avoid confusion.
