I want to use canvas package classes ( SignedRequest etc.) in my app only by adding dependencies.
Could I talk you into extracting these classes as a library?

In the pom there is a version of jetty which is already EOL (https://wiki.eclipse.org/Jetty/Howto/CipherSuites)
If I replace the webapp with a new version (e.g. 9.4.35.v20201120) I get the following error when starting jetty.

I'm trying to use the example of the Canvas app on https://developer.salesforce.com/docs/atlas.en-us.platform_connect.meta/platform_connect/quick_start_run_the_app_locally.htm. At the point "Run the web App locally" I get the error message "SSL_ERROR_NO_CYPHER_OVERLAP".

I'm getting errors:

Problem accessing /examples/hello-world/index.jsp. Reason:

    PWC6033: Unable to compile class for JSP

PWC6199: Generated servlet error:
The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files

PWC6199: Generated servlet error:
The type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class files

Not sure what to do. Java 8 on Mac with MVN 3.5.2

I create a server and run it in local. Chrome and FireFox didn't accept passing https . (I use lastest version).

A question about using localStorage in CanvasApp, docs describes that localStorage is denied , but I tested a website with localStorage based token storage works well.
So I want to understand the purpose (or concerns) of the prohibition of the document statement here

hey

I've added the Javascript Canvas SDK(to be precise the canvas-all.js library) to my NodeJS project and there are some functions that seem to be missing like 'autogrow' that are referenced in the lates canvas dev docs.

For example:

 // Turn on auto grow with default settings.
Sfdc.canvas(function() {
    sr = JSON.parse('<%=signedRequestJson%>');
    Sfdc.canvas.client.autogrow(sr.client);
});

Throws the following error:

Uncaught TypeError: Object #<Object> has no method 'autogrow' 

Hope am not missing anything trivial.

The version attribute of the POM still reads 1.0-SNAPSHOT although the official version is 41.0. May I suggest to synchronize the values?

I cloned the git repository "https://github.com/forcedotcom/SalesforceCanvasFrameworkSDK” and hosted on heroku for Canvas demo.
For some reason index.jsp is getting the signed request as null from salesforce. (“ This App must be invoked via a signed request!" ). Can you please share any ideas to fix the issue?

Hi there, I tried both the Canvas App Heroku Quick Start and also the Advanced, following the exactly steps as describe on the Canvas Development Guide for version 40 '17, but in the Canvas Previewer I'm receiving the error message: "Unable to retrieve signed request from the server. Please try your request later".

I have configured the API (Enable OAuth Settings) and also the Canvas App Settings Access Method with Signed Request (POST), also have the "Admin approved users are pre-authorized" configured with the Administrator assigned to the Canvas App.

I spent several hours trying to figure out what else can be missing, any help is really appreciated,

Thanks,

[ERROR] error: Source option 6 is no longer supported. Use 7 or later.
The build was failing on running "mvn package"

I had to fix it by changing pom.xml to following

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
        <!-- 
            Not working 
        <source>${java.version}</source>
        <target>${java.version}</target>
         -->
    </configuration>
</plugin>

Please review if this is a good general fix for pom.xml, or any other change is needed else where.
