Having an issue with a particular compiled class on Appian version 22.4.0

I don't know as far as it is an internal class as you said.

I would suggest to use appian sdk as a reference in your project (you will find it in _admin/sdk)

Got it. I think you are correct.
I am reading that the com.appiancorp.core.expr.portable.PortableNamedTypedValue is not publicly available since it is an internal class. Any idea what dependency/jar I can find it at ?

That's because in java, you can reference in your class classes located in another library- Probably the class PortableNamedTypedvalue is located in another jar.

That's why you add dependencies in your pom project, or the classpath if you are using a non maven project

The imported classes referenced in a compiled class coming from the jar should also be in that same jar.
The example I shared is the NamedTypedValue.class which I am able to find in the appian jar ver 22.4. But one of the classes referenced by the NamedTypedValue.class (com.appiancorp.core.expr.portable.PortableNamedTypedValue) is missing in the same jar.

Could you be missing some dependency in your POM file?

And could you get the SDK (which is included in the installation) and use it as a reference rather than using the dependency (which only encapsulates the call to the SDK)?

Hi David,

Thanks for the reply.
I didn't think that would solve my problem since it is able to locate the jar from my .m2 forlder.

This is the class that is not able to access another compiled class which it imports:

import com.appiancorp.core.expr.portable.PortableNamedTypedValue;

import com.appiancorp.type.NamedType;

import com.google.common.annotations.GwtCompatible;

import java.util.ArrayList;

import java.util.Collection;

import java.util.Iterator;

import java.util.List;

import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

import javax.xml.namespace.QName;

import org.apache.commons.lang.builder.EqualsBuilder;

import org.apache.commons.lang.builder.HashCodeBuilder;

import org.apache.commons.lang.builder.ToStringBuilder;

@XmlJavaTypeAdapter(NamedTypedValueJaxbAdapter.class)

@GwtCompatible

public class NamedTypedValue extends TypedValue implements NamedType, PortableNamedTypedValue {

The

import com.appiancorp.core.expr.portable.PortableNamedTypedValu is not contained in the appian plugin jar (v 22.4) that I am using.

In addition to the NamedTypedValue.class, I have another class which is also not able to access a number of imported classes and hence throws "cannot access... " error.

To verify if the classes are indeed missing i run " jar tf .\appian-22.4.0.jar | Select-String ".class" " command on the jar to list all the classes in the jar. I don't see the classes that are reported in the "cannot access..." error.

Does this mean Appain forgot to include those classes in the jar ?

Since version 22.4 jar is not available for download from the Appian site, how can I get an updated and latest of appian skd on version 22.4 ?

At this time we are not looking to upgrade to the latest version.

Why don't you reference the sdk library (as external libraru) directly in you project and check if it works?

Thanks for the response.
I am using appian version 22.4 and compiling using java 8.

<groupId>com.appiancorp</groupId>

<artifactId>appian</artifactId>

</dependency>

I am running it locally using version 22.4 jar in .m2 repository.

I don't see the following class:

import com.appiancorp.core.expr.portable.PortableNamedTypedValue;

When I try to search for the missing compiled class in the jar, using java's jdk command , the class is actually missing.
Yet the class appears as one of the imports of the "com.appiancorp.suiteapi.type.NamedTypedValue.class"

I hope that give you more context to my issue.

I am eager to try with an updated build for appian version 22.4.0 but how can I get it ?

Recommend, Recompile all plugins with SDK 22.4.0 and Java 8 to match your runtime environment.

Hey, this usually happens when the compiled plugin or class was built with a java or appian SDK version that doesn’t match what appian 22.4 expects. make sure you’re compiling with the java version that appian supports, and check that the SDK you used matches the version of appian you’re running. If the plugin came from a third party, see if there’s an updated build for 22.4. also have a look at the tomcat logs for errors like “unsupported class version error” to confirm if it’s a version mismatch.
