Got a solution. It looks like the groovy version 2.4.6 does not support both output parms and resultset.
The fix is available in 2.4.7 with callwithRows() method.

Thanks knute for the help provided so far

My stored procedure, gives output both as result set and in output parameter.
Yes, I am using rs inside the for loop to get the result set output , which is working fine.
To get the output parameter values, I am not able to get it.
Note:When I print input parameter values using .value , it works fine.

Thanks for the response Knute.
The stored procedure is returning the value 5 in the output parameter . I am trying to get the value from my groovy dao layer.
I tried different parsing options for the params , but nothing seems to work out

For params1 , I getting the value as groovy.sql.Sql$7@3ec4d8f6
For params2 , I am getting the below exception

stack_trace":"groovy.lang.MissingPropertyException: No such property: value for class: groovy.sql.Sql$7\n\tat org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:53) ~[groovy-all-2.4.6-indy.jar:2.4.6]\n\tat org.codehaus.groovy.vmplugin.v7.IndyGuardsFiltersAndSignatures.unwrap(IndyGuardsFiltersAndSignatures.java:177) ~[groovy-all-2.4.6-indy.jar:2.4.6]\n\tat org.codehaus.groovy.vmplugin.v7.IndyInterface.selectMethod(IndyInterface.java:228) ~[groovy-all-2.4.6-indy.jar:2.4.6]\n\tat com.etc.MyDAO.getSPValues(MyDAO.groovy:61)

Hi
I am calling a stored procedure using groovy sql to fetch the output result set and output parameters. Below is my high level code. When i am trying to print my output parameter,I am not getting the output as a readable object. Any thoughts on how can I parse the output parameter.
def params = [ Sql.INTEGER(500), //input parm to stored proc Sql.SMALLINT(1), //input parm to stored proc Sql.INTEGER //output parm to stored proc ] def sqlCall = "{CALL SP1234(?,?,?)}" //prepare stored proc call statement List<GroovyRowResult> rows = sql.execute(sqlCall, params) //invoke stored proc for (GroovyRowResult rs : rows) { //logic to iterate result set - able to get output records } println "params1 "+params[2].value //expecting integer output from stored proc but not able to get the output value println "params2 "+params.get(2) //expecting integer value from store proc output but getting a data not in readable format.

Hi,
I have a dockerized container of camel router which does sftp from remote host to VM local folder. If I just run my code in VM in conventional way (ie java -jar my-sftp-camel-router.jar), it downloads all 5000 files. However, when I run the same as docker image using docker run -P /tmp/:/tmp/ my-sftp-camel-router-image it fails after downloading around 12 files. Both cases works fine in my local machine, but not on VM.Any thoughts on this.

Hi,
I am trying to add few few objects to treeset, but it is giving me an exception "Exception in thread "main" java.lang.ClassCastException: demo.People cannot be cast to java.lang.Comparable"
Any idea on this? Below is the code snippet that I am trying.

package demo; import java.util.ArrayList; import java.util.Collection; import java.util.List; import java.util.SortedSet; import java.util.TreeSet; class People { private String name; People(String name) { this.name = name; } public String toString() { return name; } } public class DemoCollections { public static void main(String[] args) { List<People> arrayList = new ArrayList<People>(); SortedSet<People> treeSet = new TreeSet<People>(); addValues(arrayList); addValues(treeSet); showValues(arrayList); System.out.println(); showValues(treeSet); } private static void addValues(Collection<People> cols) { cols.add(new People("Sue")); cols.add(new People("Bob")); cols.add(new People("Steve")); cols.add(new People("Clare")); } private static void showValues(Collection<People> cols) { for (People element : cols) { System.out.println(element); } } }

Hi,

For Integer class, if I compare 2 objects with == , it compares the values of the object, but for Double,it compares only the location of the objects rather than values.
I can overcome in Double object by overriding .equals method. But my question is though both Integer/Double are classes and both implement .equals, why == works fine for Integer object and not for Double.
Any ideas?

Integer myInt1 = 7; Integer myInt2 = 7; System.out.println("Both objects are "+(myInt1 == myInt2)); //returns true, how? Double myDouble1 = 7.2; Double myDouble2 = 7.2; System.out.println("Both objects are "+(myDouble1 == myDouble2));//returns false

The database is an embedded one and comes along will spring boot.

Hi, I was trying hands on in creating a batch service from spring.io site. While executing the batch, I was getting the following error

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [insert into people (first_name, last_name) values (?, ?)]; nested exception is java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: PEOPLE

I am suspecting this could be a previlage issue since the database is running as user 'su'. But I not sure how I change the user name since everything is embedded in spring boot config Or is this is different issue

Hi, I have 2 classes, Quote and Value. In Quote class, I have an variable for type Value. In both classes , I have implemented toString() method.
Now I am calling the toString() method using below code.

Quote quote = new Quote(); System.out.println(quote);

I was expecting the values in both Quote and Value classes readable. But the toString() method from Value class is not getting invoked. The code is below. Could you please help why it is not invoking.

package webservice; import com.fasterxml.jackson.annotation.JsonFormat.Value; import com.fasterxml.jackson.annotation.JsonIgnoreProperties; @JsonIgnoreProperties(ignoreUnknown=true) public class Quote { private String type; private Value value; public Quote(){ } public String getType() { return type; } public void setType(String type) { this.type = type; } public Value getValue() { return value; } public void setValue(Value value) { this.value = value; } @Override public String toString() { return "Quote [type=" + type + ", value=" + value + "]"; } }

package webservice; import com.fasterxml.jackson.annotation.JsonIgnoreProperties; @JsonIgnoreProperties(ignoreUnknown = true) public class Value { private Long id; private String quote; public Long getId() { return this.id; } public void setId(Long id) { this.id = id; } public String getQuote() { return this.quote; } public void setQuote(String quote) { this.quote = quote; } @Override public String toString() { return "Value [id=" + id + ", quote=" + quote + "]"; } }

Hi , I was learning multithreading concepts from a tutorial. I tried the below code.


class Runner extends Thread { public void run() { for (int i = 0; i < 3; i++) { System.out.println(i); } try { Thread.sleep(1000); } catch (InterruptedException e) { System.out.println("Exception in thread"); } } } public class App { public static void main(String[] args) { Runner runner1 = new Runner(); runner1.start(); Runner runner2 = new Runner(); runner2.start(); } }

I was expecting the output as
0
0
1
1
2
2

but I am getting as

0
1
2
0
1
2

It is working sequentially and I don't find to observe any threading concept. Any idea
