Missing dependent jar file while uploading custom action (MII 12.2)

[shaji_chandran]

Hi Experts,

I am trying to develop a custom action at MII 12.2 version. I have packaged my required java classes files inside a jar file with a catalog xml file mentioned below. I have  added the dependent jar files inside the main jar file which is ReadActions.jar. At MII 12.2 I do not see any place where I can upload the dependent jar files. So I added those inside the Assembly jar file. But while uploading custom action jar file I am getting and error as com.sap.xmii.Illuminator.logging.LHException: Missing dependency file xxx1.jar

Can anyone help me on this? Did I mention the dependent jar files correctly (comma separator) in the catalog.xml ?

<?xml version = "1.0" encoding="utf-8" ?>

<ComponentCatalog>

<Category Name="ReadActions" Description="ReadActions">

<Component Type="Action"

Name="ReadData"

Description="Reading"

Label="ReadData"

ClassName="xxx.xxx.ReadActions"

AssemblyName="ReadActions.jar"

Dependencies="xxx1.jar,xxx2.jar,xxx3.jar,xxx4.jar"

HelpFileName="" />

</Category>

</ComponentCatalog>

Thanks

Hi Shaji,

You can zip up all the jar files and upload them as a single file to the custom actions screen,

You have mentioned the dependencies correctly.

Hi Anushree,

I have done the same only. But my file type is jar. This jar files includes all java classes for custom action and dependent jar files as well. Should I change the file type to Zip?  Will that make any difference?

Thanks

Hi Shaji,

Can you please tell us what is the file structure inside the jar file you are uploading.

Hi Anushree,

Thanks for you time to respond.

Please see the file structure of jar file

META-INF/

META-INF/MANIFEST.MF

excel/

excel/action/

excel/action/ExcelActions.class

excel/action/ExcelConfigurationDialog.class

catalog.xml

xxx1.jar

xxx2.jar

xxx3.jar

xxx4.jar

Thanks

Hi Shaji,

Try making a separate jar file such that it has:

META-INF/

META-INF/MANIFEST.MF

excel/

excel/action/

excel/action/ExcelActions.class

excel/action/ExcelConfigurationDialog.class

catalog.xml

Zip the jar file with :

xxx1.jar

xxx2.jar

xxx3.jar

xxx4.jar

Your final zip file should have 5 jars only. Let us know if it works.

Hi Anushree,

No luck this time as well.

Here is my catalog xml

<?xml version = "1.0" encoding="utf-8" ?>

<ComponentCatalog>

<Category Name="ExcelActions" Description="ExcelActions">

<Component Type="Action"

Name="ReadData"

Description="Reading Data "

Label="ReadData"

ClassName="excel.action.ExcelActions"

AssemblyName="ExcelAction.jar"

Dependencies="main.jar"

HelpFileName="" />

</Category>

</ComponentCatalog>

Hi Shaji,

Your jar file structure should look like:

META-INF/

META-INF/MANIFEST.MF

excel/

excel/action/

excel/action/ExcelActions.class

excel/action/ExcelConfigurationDialog.class

catalog.xml

all bundled up as XYZ.jar

Then XYZ.jar and main.jar should be bundled up as a jar or a zip say ABC.zip.

If you unzip ABC.zip you should see XYZ.jar and main.jar.

Hi Anushree,

I applied the change which you mentioned. Now I am able to deploy custom action at MII 14.0 where I can upload the dependency file separately. But at MII 12.2 I am still getting the same error (com.sap.xmii.Illuminator.logging.LHException: Missing dependency file main.jar ). Also I could not find any place in MII 12.2 upload dependency jar files.

Please help

Thanks

Hi Shaji,

So you have created a .zip(or jar?) file which has both your ExcelActions.jar and Main.jar as mentioned by me above but still you are not able to upload your action?

It should work. If it doesn't, maybe its a system bug. Could you mention your complete MII version.

Regards,

Anushree

It may be caused by the 12.2 server using an older version of the Java JRE than your action or libraries were compiled with.

Hi Christian,

Yes I had received such error (Unsupported minor version) earlier. But I fixed it by compiling at right version.

Anyway thanks for your response

Thanks

Hi Anushree,

Now I realized the issue. I was accessing my MII server through Remote Desktop Connection and my jar files were stored on local machine. I used to upload the custom action jar files from my local machine. I think while browsing jar files from local machine created the issue (jar files might have corrupted). Now I copied the jar files to the MII server and browsed from there which worked.

Sorry for wasting your time.

I appreciate your continuous support again

Thanks

Hi

I am able to deploy the custom action succesfully. But while running the custom action I am getting java.lang.NoClassDefFoundError. I am sure that this java class exists inside the jar file through which I deployed the custom action.

Do we need to set any classpath or put jar in a particular folder?

Thanks

Shaji

At last it worked. I can't have 3 level hierarchy\compression inside jar files

I kept all my actions jar and dependent jars inside one jar file and uploaded the same. This approach worked.

Thanks
