I am working with the ETrade Java API. I was able to use most of the functions but I am having trouble with the previewEquityOrder and the previewOptionOrder functions. Here are the error messages/ exceptions I get when I call these functions:
URL : https://etwssandbox.etrade.com/order/sandbox/rest/previewequityorder
? Java exception occurred:
com.etrade.etws.sdk.common.ETWSException
at com.etrade.etws.sdk.common.ETWSUtil.constructException(ETWSUtil.java:9)
at com.etrade.etws.sdk.core.ConnectionUtils.invoke(ConnectionUtils.java:90)
at com.etrade.etws.sdk.core.ConnectionUtils.invoke(ConnectionUtils.java:32)
at com.etrade.etws.sdk.client.OrderClient.previewEquityOrder(OrderClient.java:145)
For the previewOptionOrder:
URL : https://etwssandbox.etrade.com/order/sandbox/rest/previewoptionorder
? Java exception occurred:
com.etrade.etws.sdk.common.ETWSException
at com.etrade.etws.sdk.common.ETWSUtil.constructException(ETWSUtil.java:9)

The following Java code can reproduce the problem. You can compile this code on a Mac using the following command. On windows machine, replace the " : " with " ; " as the separator.
javac -classpath "./commons-codec-1.3.jar:./commons-httpclient-3.1.jar:./commons-httpclient-contrib-ssl-3.1.jar:./commons-lang-2.4-javadoc.jar:./commons-lang-2.4-sources.jar:./commons-lang-2.4.jar:./commons-logging-api.jar:./commons-logging.jar:./etws-accounts-sdk-1.0.jar:./etws-common-connections-1.0.jar:./etws-market-sdk-1.0.jar:./etws-oauth-sdk-1.0.jar:./etws-order-sdk-1.0.jar:./log4j-1.2.15.jar:./xstream-1.3.1.jar:" test.java
You can run the compiled class from command line using the following command:
java -classpath "./commons-codec-1.3.jar:./commons-httpclient-3.1.jar:./commons-httpclient-contrib-ssl-3.1.jar:./commons-lang-2.4-javadoc.jar:./commons-lang-2.4-sources.jar:./commons-lang-2.4.jar:./commons-logging-api.jar:./commons-logging.jar:./etws-accounts-sdk-1.0.jar:./etws-common-connections-1.0.jar:./etws-market-sdk-1.0.jar:./etws-oauth-sdk-1.0.jar:./etws-order-sdk-1.0.jar:./log4j-1.2.15.jar:./xstream-1.3.1.jar:" test <consumer_key> <consumer_secret>
You will need to pass in the ETrade consumer key and consumer secret as command line arguments to run this.
Notice that the authentication part works which is verified by getting the accounts list.

I posted this on the ETrade community forum but that forum is not very active. I also sent a request to ETrade and haven't gotten a reply yet. If I get a solution from them, I will come back and post it here. In the mean time any help is greatly appreciated.
