Steps to reproduce the behavior

Backtrace/logs

[backtrace/logs]

[chetan]

Can you describe how you started the application? Which method and command line/configuration options if any?

[mikkazan]

Downloaded windows version to my Windows 10 home machine. Started for the first time waited a little then exited the app. Started the app again. Still no issues. @rfikki Can you please provide full log as well the command you've started cakeshop with? Also, could you provide your version of java? My steps were pretty simple Downloaded war into directory where my user can execute files. Ran java -jar cakeshop-0.9.0-x86_64-windows.war

[chetan]

Please paste the full console output as a gist and paste the link here. I think the root cause may lie elsewhere

[rfikki]

So, steps to reproduce are I have a running completely synced latest version of geth 1.5.6 develop branch that I attach with. I first run "java -jar cakeshop.war example" command to create the initial files as stated in your wiki. After the directory has been created I open the application.property file per your wiki and change the rpc port to 8545 and make all the stated needed changes per the wiki. The application starts up and I can visit the application at the localhost location in the browser. However browser application does not display any of the data except for the incoming block numbers. Looking at the terminal the error provided in the original post above repeats itself over and over again.

[chetan]

So by 'completely synced' do you mean against the public Ethereum chain? This isn't really a use case we've tested in a while as we primarily target the local development of smart contracts (i.e., develop the contract locally and then take it and deploy it on some other chain). That said, I'll give it a try and see if I can reproduce that error.

[rfikki]

It is a running testnet ropsten geth that performs well with other smart contracts. Nothing wrong and it is fully synced when latest block is compared to etherscan.io, I run other smart contracts on it using truffle and know it is not a problem with my chain. Again as I have stated I am running your "java -jar cakeshop.war example" command. I then run "java --jar cakeshop which seems to find the running geth but outputs the error message as stated above. Java version is 8.

[rfikki]

This is the command I use to start geth:

"C:\projects\ethereum_develop_ropsten\geth.exe" --testnet --networkid 3 --identity "GETH DEVELOP ROPSTEN" --datadir C:\projects\ethereum_develop_ropsten\testnet_data --fast --jspath "c:\projects\ethereum_develop_ropsten\javascript" --unlock "0, 1" --shh --rpc --rpcaddr=127.0.0.1 --rpcapi "eth,net,web3,shh" --ipcapi "admin,debug,eth,miner,net,personal,shh,txpool,web3" --rpcport=8545 --verbosity=3 --minerthreads "2" --rpccorsdomain="*" --solc "C:\projects\solc\solc.exe" console 2>> C:\projects\ethereum_develop_ropsten\GETH_DEVELOP_ROPSTEN_CONSOLE.log 2^&1

[mikkazan]

I'm concerned about this --rpcport=8545. Shouldn't it be --rpcport 8545? Can you verify that rpc is actually up and listening on port 8545. Also, please use all rpc api endpoints points, which are in application.properties. For instance I do not see admin endpoint in your geth startup command.

[chetan]

@rfikki I think changing your startup command to the following should fix it:

"C:\projects\ethereum_develop_ropsten\geth.exe" --testnet --networkid 3 --identity "GETH DEVELOP ROPSTEN" --datadir C:\projects\ethereum_develop_ropsten\testnet_data --fast --jspath "c:\projects\ethereum_develop_ropsten\javascript" --unlock "0, 1" --shh --rpc --rpcaddr=127.0.0.1 --rpcapi "admin,debug,eth,miner,net,personal,shh,txpool,web3" --ipcapi "admin,debug,eth,miner,net,personal,shh,txpool,web3" --rpcport=8545 --verbosity=3 --minerthreads "2" --rpccorsdomain="*" --solc "C:\projects\solc\solc.exe" console 2>> C:\projects\ethereum_develop_ropsten\GETH_DEVELOP_ROPSTEN_CONSOLE.log 2^&1

Note the updated list passed to --rpcapi. I'll be updating the docs soon to clarify the settings we need enabled in geth for this scenario.

[rfikki]

Thanks @chetan, will give that a shot.

[rfikki]

I changed the --rpciapi flags as you have suggested to --rpcapi "admin,debug,eth,miner,net,personal,shh,txpool,web3" and got the following error, note I included a copy of application.properties at the end of the gist: https://gist.github.com/rfikki/b7f067b59d105a315ebb9efb5540c30b

[rfikki]

In addition to the above gist I want to let you know that running java -jar cakeshop.war spawns a running node.js server that does not get terminated when you exit the cakeshop inside the terminal. I have to manually go to the running applications in windows and terminate it before I can restart cakeshop. Just wanted to let you know this.

[chetan]

Ok, looks like geth is returning that 403 Forbidden when trying to call eth_sendTransaction for some reason. Are you still trying to connect to the public testnet? Was there any error output in the window where you ran geth?

In general, I would suggest running on an offline/private chain instead. I'll have to try connecting to testnet and see if I can reproduce myself (@mikkazan also reported having some issues with testnet).

[chetan]

re: node process -could be an issue cleaning it up on Windows. I'll open a separate issue to track that. Thanks!

[rfikki]

I am running the ropsten public ethereum testnet. and have no problem connecting to my running geth node with other applications.

[rfikki]

I see no errors at all in the terminal for my running geth ropsten node. My geth node runs like a charm. The issue is with cakeshop.

[rfikki]

I am a bit confused because when running geth --help these are the flags, they seem more limited then the flags you are using for --rpcapi.

API AND CONSOLE OPTIONS: --rpc Enable the HTTP-RPC server --rpcaddr value HTTP-RPC server listening interface (default: "localhost") --rpcport value HTTP-RPC server listening port (default: 8545) --rpcapi value API's offered over the HTTP-RPC interface (default: "eth,net,web3") --ws Enable the WS-RPC server --wsaddr value WS-RPC server listening interface (default: "localhost") --wsport value WS-RPC server listening port (default: 8546) --wsapi value API's offered over the WS-RPC interface (default: "eth,net,web3") --wsorigins value Origins from which to accept websockets requests --ipcdisable Disable the IPC-RPC server --ipcapi value APIs offered over the IPC-RPC interface (default: "admin,debug,eth,miner,net,personal,shh,txpool,web3") --ipcpath "geth.ipc" Filename for IPC socket/pipe within the datadir (explicit paths escape it) --rpccorsdomain value Comma separated list of domains from which to accept cross origin requests (browser enforced) --jspath loadScript JavaScript root path for loadScript (default: ".") --exec value Execute JavaScript statement (only in combination with console/attach) --preload value Comma separated list of JavaScript files to preload into the console

[rfikki]

I guess you will update your docs to reflect that you cannot run --rpcapi with the default flags.

I do have one more question when I attach to my local running testnet with cakeshop, do I need to change the datadir flag to the location of my running geth's datadir inside the application.properties file?

[ice09]

I had this error, for me went away with

geth --datadir datadir --networkid 3 --rpc --rpcapi admin,db,eth,debug,miner,net,shh,txpool,personal,web3 --rpccorsdomain "*"

for connecting to Ropsten

[rfikki]

Hey @ice09 what changes did you make to your applications.properties file? Can you share the settings?

[ice09]

Sure, but as I understand, these settings have no effect due to geth.auto.start=false and the geth.url? This is quite confusing, because in the webapp, eg. the network-id is shown from the settings, but it is 3 for Ropsten in fact.

[rfikki]

You are on ubuntu? I am pretty sure this might be an issue with running on windows.

[ice09]

yes, Ubuntu 16.04 LTS

[rfikki]

Ok, will give it a try in my 16.04 virtual machine when I get a chance.

[ice09]

ok, but as I said, I don't have this error anymore, with the settings I git rid of it, I am sure that it was due to some missing rpcapi params, that's why I posted it here.

[ice09]

sorry, now I get it, you wanted to reproduce without the error :) I have a different error (https://github.com/jpmorganchase/cakeshop/issues/4), but not this one anymore. I am pretty sure that it was about the rpcapi params.

[rfikki]

Okay, was able to get a bit further along by making a few adjustments. Cakeshop is now connecting to the local geth, but after a few seconds still crashes. At least I can see it creating the contracts and connecting to my local node running ropsten testnet now. Now to figure out what is causing it to crash here is the latest error: c:\projects\cakeshop>java -jar cakeshop.war Defaulting to spring profile: local Extracting geth to C:\projects\cakeshop\data\geth INFO 2016-12-19 15:17:37,390 [main] (StartupInfoLogger.java:48 ) Starting SpringBootApplication on ASUS with PID 16248 (started by Rocky in c:\projects\cakeshop) INFO 2016-12-19 15:17:37,393 [main] (SpringApplication.java:670) The following profiles are active: container,spring-boot,local WARN 2016-12-19 15:17:40,328 [main] (ConfigurationClassEnhancer.java:347) @Bean method AppConfig.propertySourcesPlaceholderConfigurer is non-static and returns an object assignable to Spring's BeanFactoryPostProcessor interface.

It is indeed a bit confusing at present. Cakeshop was originally developed under the premise of using an internally bundled version of geth to make it easier for first-time developers to bootstrap the environment. The geth.auto.start/stop settings were added as a sort of escape hatch for working with an "unmanaged" version of geth and thus the UI isn't entirely consistent when in this mode.

[rfikki]

Ok, I have it running on Windows, but it is throwing a bunch of warnings in the terminal. At least I can check it out in the browser: These are the warnings that keep repeating: WARN 2016-12-19 15:38:15,274 [BlockSaver-42] (SavingBlockListener.java:118) Failed to load transaction details for tx com.jpmorgan.cakeshop.error.APIException: Contract does not exist at 0xc47aa6c1987ec4737b40a327620c31fd1995602f at com.jpmorgan.cakeshop.service.impl.ContractServiceImpl.get(ContractServiceImpl.java:228) at sun.reflect.GeneratedMethodAccessor77.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:302) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:190) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:157) at org.springframework.cache.interceptor.CacheInterceptor$1.invoke(CacheInterceptor.java:52) at org.springframework.cache.interceptor.CacheAspectSupport.invokeOperation(CacheAspectSupport.java:320) at org.springframework.cache.interceptor.CacheAspectSupport.execute(CacheAspectSupport.java:353) at org.springframework.cache.interceptor.CacheAspectSupport.execute(CacheAspectSupport.java:302) at org.springframework.cache.interceptor.CacheInterceptor.invoke(CacheInterceptor.java:61) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:208) at com.sun.proxy.$Proxy98.get(Unknown Source) at com.jpmorgan.cakeshop.service.impl.EventServiceImpl.processEvents(EventServiceImpl.java:86) at com.jpmorgan.cakeshop.service.impl.TransactionServiceImpl.processTx(TransactionServiceImpl.java:137) at com.jpmorgan.cakeshop.service.impl.TransactionServiceImpl.get(TransactionServiceImpl.java:202) at com.jpmorgan.cakeshop.db.SavingBlockListener.saveBlock(SavingBlockListener.java:115) at com.jpmorgan.cakeshop.db.SavingBlockListener$BlockSaverThread.run(SavingBlockListener.java:48)

@rfikki FYI, I just cut 0.9.1. Please give it a try and let me know how it goes. I also updated the configuration documentation at https://github.com/jpmorganchase/cakeshop/blob/master/docs/configuration.md
